INTRODUCTION
It is noted that the markets and industries on infotainment services for vehicles (known as in-
vehicle infotainment services) have been growing rapidly. It is envisioned that a variety of
infotainment (or multimedia) devices and services will be newly developed for personal and
public vehicles in the future. Such devices include navigations, cameras, speakers, headrest
displays, air-conditioners, thermometers and heated seats, and lights.
A set of standards have so far been developed on configurable car infotainment services (CCIS)
with the IEC 63246 series. However, the CCIS standards have been basically designed for
personal users, such as car owners. In the meantime, there is also a crucial need to provide a
variety of infotainment services for public vehicles (PVIS) such as bus or train.
PVIS services have different requirements and features from CCIS services. For user type,
CCIS is targeted for one or two users (such as car owner), whereas PVIS are for a large number
of guests or passengers within the public vehicle. For device type, CCIS deals with the personal
devices (property or belonging) in the car, whereas PVIS will be targeted for a variety of public
devices that are contained in a public vehicle. Some PVIS services can be provisioned by
interworking with the external networks, as shown in the bus information service. For service
duration, CCIS usually provide long-term services, whereas PVIS can provide short-term
service during which a guest stays within a public vehicle.
From these observations, it is noted that there are many different features and requirements
between CCIS and PVIS. Accordingly, there is a need for standardization on PVIS. In particular,
PVIS will employ a set of agents to effectively manage a large number of users or devices.
The PVIS series (IEC 63479) describes infotainment (multimedia) services for terrestrial public
vehicles, such as bus, train, or subway. It is not applicable to public vehicles, such as airplane
or ship. For this purpose, the following issues are addressed: 1) identify a variety of functional
requirements for provisioning of PVIS, 2) design the PVIS framework, based on the identified
requirements. The PVIS standards are expected to provide guidelines on PVIS services for a
large number of users/devices, and to encourage development of new (enhanced) PVIS
services (possibly by interworking with the external systems).
The IEC 63479 consists of the following parts:
– Part 1: General
– Part 2: Requirements
– Part 3: Framework
IEC TR 63479-1 describes general considerations and system model for PVIS, with some
examples of PVIS services.
IEC 63479-2 describes the functional requirements for PVIS.
IEC 63479-3 describes the framework, including the functional information flows between
functional entities.

4 Overview
PVIS consist of a diverse ecosystem of entities, each contributing to the system's operation and
functionality. These entities can be categorized into two main groups:
– PVIS support entities: these entities are responsible for supporting the core functions
required by the PVIS. They include the PVIS master, PVIS agent, and PVIS devices. The
PVIS master serves as the central command, controlling and coordinating activities within
the system. The PVIS agent facilitates the connection between the master and the devices,
while the PVIS devices deliver the actual infotainment content to the passengers.
– PVIS user entities: these entities engage with the PVIS system on a more transient basis.
They include passenger devices, content providers, and external applications. Passenger
devices enable users to interact with the system, content providers supply the infotainment
materials, and external applications offer additional functionalities to enhance the overall
user experience.
The PVIS framework defines the functions that the PVIS master, agent, and devices shall
support in order to manage infotainment services effectively and deliver them to passengers
seamlessly.
Figure 1 illustrates how each entity has a specific set of PVIS functions to ensure the smooth
operation of PVIS. It is noted in the figure that the PVIS master should be able to perform the
functions of the PVIS agent, and the PVIS agent includes the functions of the PVIS device.
Figure 1 – PVIS entities and functions
Figure 2 presents a reference architecture of the PVIS system, which includes the six core
functions and the three interworking functions. The core functions are specifically designed to
meet the functional requirements of each entity, while the interworking functions enable smooth
interaction between these entities. The details of these functions are described in Clause 5,
Clause 6 and Clause 7.
Figure 2 – Overview of reference function model
5 Reference model for core functions
5.1 General
The PVIS reference model for core functions comprises several functional modules that
facilitate efficient management and utilization of infotainment services. As illustrated in Figure 3,
PVIS encompass the following modules: authentication management, profile management,
device management, content management, connectivity management, and history management.
Figure 3 – PVIS reference model for core functions
5.2 Authentication management function
The authentication management function within PVIS is responsible for delivering customized
services to authenticated users by leveraging their registered information. This function consists
of two crucial subfunctions: certification and permission.
The certification subfunction ensures the identification of each entity within the system and
generates access tokens that grant specific privileges for a limited duration. These access
tokens shall be included in all exchanged messages by the entity, enabling secure and
authorized communication.
The permission subfunction is responsible for validating exchanged messages and governing
the permissions associated with devices and content. Different entities within the PVIS service
can have varying levels of permission to operate devices and access content. The validation
process relies on the access tokens issued by the certification module, ensuring that only
authorized entities can perform permitted actions.
5.3 Connectivity management function
In PVIS, the connectivity information associated with the various PVIS entities plays a crucial
role in delivering efficient and secure services. This connectivity information is represented by
connection and session data.
Within a PVIS system, all functional entities, except for the PVIS master, are required to register
either with the PVIS master or the PVIS agent. During this registration process, a session token
is assigned to each entity. This session token is then included in all subsequent communications,
enabling the PVIS to maintain session context and track entity activities. For instance, a session
for a PVIS device includes details about the device's current state and occupant. Similarly, a
session related to a passenger's device encapsulates information such as the specific PVIS
device being used and the content currently being accessed. This session information forms
the foundation for maintaining effective and personalized interactions within the PVIS.
Furthermore, it facilitates the verification of entity permissions, ensuring secure and authorized
interactions within the system.
A connection is established between two entities to facilitate the exchange of messages.
5.4 History management function
The history management function is an essential component of the PVIS framework,
responsible for recording, maintaining, and utilizing historical data related to the usage of
infotainment services. It plays a critical role in improving service quality, enabling personalized
experiences, and supporting decision-making processes.
The module for service usage analytics focuses on acquiring and managing key usage
information, such as the most frequently accessed types of services by users. This data serves
as a foundation for enhancing user convenience and enables functions like content
recommendation and service personalization. Additionally, this information can be shared with
content providers to improve their services.
Furthermore, the history management function oversees the management of system historical
log information. Log information is vital in diagnosing and resolving system errors within the
PVIS. By providing a comprehensive record of system activities and events, it facilitates timely
identification, analysis, and resolution of any issues, contributing to the stability and reliability
of the system.
5.5 Profile management function
Profile management function serves as a repository for storing and organizing pertinent details
associated with devices, agents, and content. These profiles encompass a range of information,
including device specifications, connectivity attributes, access permissions, preferences, and
historical usage data. By collecting and managing such information, PVIS can effectively adapt
its services to meet the specific needs and preferences of individual entities.
5.6 Device management function
In PVIS, device management involves registering devices with a PVIS master or PVIS agent.
The device management function comprises three subfunctions: provisioning, monitoring, and
control.
– Provisioning: the provisioning subfunction handles the configuration process when
registering a PVIS device. This includes assigning a unique identifier to the device, setting
up its network connections, and installing any necessary software. It also covers updating
or decommissioning devices as required.
– Monitoring: PVIS entities registered in the system should always have their latest status
accessible. This is achieved through the following operating procedures:
• Periodic status reporting: PVIS devices periodically send their status to the relevant
PVIS agent or PVIS master. This ensures continuous and controllable connection
between the entities through message exchange. By consistently reporting status, the
PVIS system maintains an up-to-date understanding of the device's status and its
surrounding environment, allowing for identification and pre-emption of potential issues.
• Status reporting on status change: when a status change is detected, the PVIS system
quickly prepares for unexpected situations.
• Querying status: The PVIS master or PVIS agent managing a PVIS device can request
the device's status at any time by sending a status report request. This is useful when a
passenger device requests the list of available devices or when an expected status
report is not received within a specific time threshold.
– Control: the device management function provides a list of available PVIS devices and
supports control operations for those devices. Passengers should obtain an access token
through the certification procedure to access this list. The request message should include
the access token and session information of the passenger device.
The PVIS master or PVIS agent verifies the validity of each request message before processing
it. If the message is valid, the passenger is allowed to control the PVIS device. When the
passenger stops using the service, the PVIS master or PVIS agent initializes the device and
makes it available for other passengers.
5.7 Content management function
The content management function enables passengers to seamlessly access and engage with
a range of content provided by different content providers, enhancing their travel experience.
This function comprises three critical subfunctions: deployment, maintenance, and delivery.
– Deployment: the deployment subfunction handles the proces

INTRODUCTION
Il est à noter que les marchés et les industries des services d'infodivertissements pour véhicules
(également appelés services d'infodivertissements embarqués dans les véhicules) ont connu
une croissance rapide. Le développement d'un éventail de dispositifs et de systèmes
d'infodivertissements (ou multimédia) pour les véhicules personnels et publics est envisagé
dans les années à venir. Ces dispositifs incluent les systèmes de navigation, les caméras, les
haut-parleurs, les écrans sur appuie-tête, les climatiseurs, les thermomètres et les sièges
chauffés, ainsi que les éclairages.
Un ensemble de normes couvrant les services d'infodivertissements configurables pour les
voitures (CCIS, Configurable Car Infotainment Services) ont été élaborées dans le cadre de la
série IEC 63246. Toutefois, les normes CCIS ont été essentiellement conçues pour les
utilisateurs personnels, comme les propriétaires de voitures. Il existe par ailleurs également un
besoin crucial de fournir une variété de services d'infodivertissements pour les véhicules
publics (PVIS, Infotainment Services for Public Vehicles), comme les bus ou les trains.
Les services PVIS ont des exigences et des fonctionnalités différentes de celles des services
CCIS. En ce qui concerne le type d'utilisateur, le CCIS s'adresse à un ou deux utilisateurs
(comme le propriétaire de voiture), tandis que le PVIS s'adresse à un grand nombre de clients
ou de passagers dans le véhicule public. En ce qui concerne le type de dispositif, le CCIS
couvre des dispositifs personnels (biens ou effets personnels) dans le véhicule, tandis que le
PVIS couvre un grand nombre de dispositifs publics qui se trouvent dans un véhicule public.
Certains services PVIS peuvent être fournis en interagissant avec des réseaux externes,
comme dans le service d'informations sur les bus. En ce qui concerne la durée du service, les
CCIS fournissent habituellement des services à long terme, tandis que les PVIS peuvent fournir
des services à court terme pendant qu'un client reste dans un véhicule public
Il ressort de ces observations qu'il existe de nombreuses fonctionnalités et exigences
différentes entre les CCIS et les PVIS. Par conséquent, il est nécessaire de normaliser les PVIS.
En particulier, les PVIS emploient un ensemble d'agents pour gérer efficacement un grand
nombre d'utilisateurs ou de dispositifs.
La série PVIS (IEC 63479) décrit les services d'infodivertissements (multimédia) pour les
véhicules publics terrestres, comme les bus, les trains ou les métros. Elle ne s'applique pas
aux véhicules publics, comme les avions ou les navires. À cette fin, les aspects suivants sont
traités: 1) identifier une variété d'exigences fonctionnelles pour la fourniture de PVIS, 2)
concevoir le cadre PVIS en fonction des exigences identifiées. La série de normes traitant des
PVIS est présumée fournir des lignes directrices sur les services PVIS pour un grand nombre
d'utilisateurs/de dispositifs et favoriser le développement de nouveaux services PVIS
(améliorés) (éventuellement en interagissant avec des systèmes externes).
L'IEC 63479 est composée des parties suivantes:
– Partie 1: Généralités
– Partie 2: Exigences
– Partie 3: Cadre
L'IEC TR 63479-1 décrit les considérations générales et le modèle de système pour les PVIS,
avec quelques exemples de services PVIS.
L'IEC 63479-2 décrit les exigences fonctionnelles pour les PVIS.
L'IEC 63479-3 décrit le cadre, y compris les flux d'informations fonctionnelles entre entités
fonctionnelles.

4 Vue d'ensemble
Les PVIS sont constitués d'un écosystème d'entités différentes, chacune contribuant au
fonctionnement et à la fonctionnalité du système. Ces entités peuvent être classées en deux
groupes principaux:
– Entités de prise en charge PVIS: ces entités sont responsables de la prise en charge des
fonctions principales exigées par le PVIS. Elles incluent le PVIS maître, l'agent PVIS et les
dispositifs PVIS. Le PVIS maître sert de commande centrale, de contrôle et de coordination
des activités au sein du système. L'agent PVIS facilite la connexion entre le maître et les
dispositifs, tandis que les dispositifs PVIS délivrent le contenu d'infodivertissement réel aux
passagers.
– Entités utilisateur PVIS: ces entités dialoguent avec le système PVIS sur une base plus
transitoire. Elles incluent les dispositifs passagers, les fournisseurs de contenu et les
applications externes. Les dispositifs passagers permettent aux utilisateurs d'interagir avec
le système, les fournisseurs de contenu fournissent le matériel d'infodivertissements et les
applications externes proposent des fonctionnalités supplémentaires pour améliorer
l'expérience utilisateur globale.
Le cadre PVIS définit les fonctions que le PVIS maître, l'agent et les dispositifs doivent prendre
en charge pour gérer efficacement les services d'infodivertissements et les livrer aux passagers
de manière transparente.
La Figure 1 représente la manière dont chaque entité dispose d'un ensemble spécifique de
fonctions PVIS pour assurer le bon fonctionnement du PVIS. Il est noté dans la figure qu'il
convient que le PVIS maître soit capable d'exécuter les fonctions de l'agent PVIS et que l'agent
PVIS inclut les fonctions du dispositif PVIS.
Figure 1 – Entités et fonctions PVIS
La Figure 2 représente une architecture de référence du système PVIS, qui inclut les six
fonctions principales et les trois fonctions d'interconnexion. Les fonctions principales sont
spécifiquement conçues pour satisfaire aux exigences fonctionnelles de chaque entité, tandis
que les fonctions d'interconnexion permettent une interaction fluide entre ces entités. Les
détails de ces fonctions sont décrits dans l’Article 5, l’Article 6 et l’Article 7.
Figure 2 – Vue d'ensemble du modèle fonctionnel de référence
5 Modèle de référence pour les fonctions principales
5.1 Généralités
Le modèle de référence PVIS pour les fonctions principales comprend plusieurs modules
fonctionnels qui facilitent la gestion et l'utilisation efficaces des services d'infodivertissements.
Comme cela est représenté dans la Figure 3, les PVIS englobent les modules suivants: gestion
d'authentification, gestion des profils, gestion des dispositifs, gestion de contenu, gestion de la
connectivité et gestion de l'historique.
Figure 3 – Modèle de référence PVIS pour les fonctions principales
5.2 Fonction de gestion d'authentification
La fonction de gestion d'authentification au sein du PVIS est responsable de la fourniture de
services personnalisés aux utilisateurs authentifiés en tirant parti de leurs informations
enregistrées. Cette fonction se compose de deux sous-fonctions essentielles: la certification et
la permission.
La sous-fonction de certification garantit l'identification de chaque entité au sein du système et
génère des jetons d'accès qui accordent des droits spécifiques pour une durée limitée. Ces
jetons d'accès doivent être inclus dans tous les messages échangés par l'entité, ce qui permet
une communication sécurisée et autorisée.
La sous-fonction de permission est responsable de la validation des messages échangés et
des permissions associées aux dispositifs et au contenu. Les différentes entités au sein du
service PVIS peuvent avoir différents niveaux de permissions pour faire fonctionner des
dispositifs et accéder au contenu. Le processus de validation repose sur les jetons d'accès
émis par le module de certification, garantissant que seules les entités autorisées peuvent
effectuer les actions autorisées.
5.3 Fonction de gestion de la connectivité
Dans le PVIS, les informations de connectivité associées aux différentes entités PVIS jouent
un rôle crucial dans la fourniture de services efficaces et sécurisés. Ces informations de
connectivité sont représentées par des données de connexion et de session.
Dans un système PVIS, toutes les entités fonctionnelles, à l'exception du PVIS maître, doivent
s'enregistrer auprès du PVIS maître ou auprès de l'agent PVIS. Au cours de ce processus
d'enregistrement, un jeton de session est attribué à chaque entité. Ce jeton de session est
ensuite inclus dans toutes les communications ultérieures, ce qui permet au PVIS de maintenir
le contexte de session et de suivre les activités de l'entité. Par exemple, une session pour un
dispositif PVIS inclut des détails sur l'état actuel du dispositif et sur l'occupant. De manière
similaire, une session relative au dispositif d'un passager encapsule des informations telles que
le dispositif PVIS spécifique utilisé et le contenu actuellement accessible. Ces informations de
session constituent la base du maintien d'interactions efficaces et personnalisées au sein du
PVIS. De plus, elles facilitent la vérification des permissions des entités, garantissant des
interactions sécurisées et autorisées au sein du système.
Une connexion est établie entre deux entités afin de faciliter l'échange de messages.
5.4 Fonction de gestion de l'historique
La fonction de gestion de l'historique est un composant essentiel du cadre PVIS, responsable
de l'enregistrement, du maintien et de l'utilisation des données historiques relatives à
l'utilisation des services d'infodivertissements. Elle joue un rôle déterminant dans l'amélioration
de la qualité des services, la mise en place d'expériences personnalisées et le soutien des
processus de prise de décisions.
Le module d'analyse de l'utilisation des services se concentre sur l'acquisition et la gestion des
informations d'utilisation clés, comme les types de services les plus fréquemment consultés par
les utilisateurs. Ces données servent de base pour améliorer la commodité des utilisateurs et
permettent des fonctions telles que la recommandation de contenu et la personnalisation des
services. De plus, ces informations peuvent être partagées avec les fournisseurs de contenu
afin d'améliorer leurs services.
En outre, la fonction de gestion de l'historique surveille la gestion des informations historiques
de journal du système. Les informations de journal sont essentielles pour le diagnostic et la
résolution des erreurs système dans le PVIS. En fournissant un enregistrement complet des
activités et des événements du système, elles facilitent l'identification, l'analyse et la résolution
en temps utile de tous les problèmes, contribuant ainsi à la stabilité et à la fiabilité du système.
5.5 Fonction de gestion des profils
La fonction de gestion des profils sert de référentiel pour le stockage et l'organisation des
informations pertinentes associées aux dispositifs, aux agents et au contenu. Ces profils
englobent une série d'informations, y compris les spécifications des dispositifs, les attributs de
connectivité, les permissions d'accès, les préférences et les données d'utilisation historiques.
En collectant et en gérant ces informations, le PVIS peut effectivement adapter ses services
pour répondre aux besoins et préférences spécifiques de chaque entité.
5.6 Fonction de gestion des dispositifs
Dans le PVIS, la gestion des dispositifs implique l'enregistrement des dispositifs auprès d'un
PVIS maître ou d'un agent PVIS. La fonction de gestion des dispositifs comprend trois sous-
fonctions: le provisionnement, la surveillance et le contrôle.
– Provisionnement: la sous-fonction de provisionnement gère le processus de configuration
lors de l'enregistrement d'un dispositif PVIS. Cela inclut l'attribution d'un identifiant unique
au dispositif, la configuration de ses connexions réseau et l'installation de tout logiciel
nécessaire. Elle couvre également les dispositifs de mise à jour ou de mise hors service,
selon les exigences.
– Surveillance: Il convient que les entités PVIS enregistrées dans le système aient toujours
leur état le plus récent accessible. Les procédures opérationnelles suivantes permettent
d'atteindre cet objectif:
• Rapports d'état périodiques: Les dispositifs PVIS envoient périodiquement leur état à
l'agent PVIS ou au PVIS maître concerné. Cela assure une connexion continue et
maîtrisable contrôlable entre les entités par l'échange de messages. En signalant l'état
de manière constante, le système PVIS maintient à jour une compréhension de l'état du
dispositif et de son environnement environnant, ce qui permet d'identifier et d'anticiper
les problèmes potentiels.
• Rapport d'état en cas de changement d'état: lorsqu'un changement d'état est détecté,
le système PVIS se prépare rapidement à faire face à des situations inattendues.
• Interrogation de l'état: Le PVIS maître ou l'agent PVIS qui gère un dispositif PVIS peut
demander l'état du dispositif à tout moment en envoyant une demande de rapport d'état.
Cela est utile lorsqu'un dispositif passager demande la liste des dispositifs disponibles
ou lorsqu'un rapport d'état attendu n'est pas reçu dans un délai spécifique.
– Contrôle: la fonction de gestion des dispositifs fournit une liste des dispositifs PVIS
disponibles et prend en charge les opérations de contrôle pour ces dispositifs. Il convient
que les passagers obtiennent un jeton d'accès via la procédure de certification pour accéder
à cette liste. Il convient que le message de demande inclue le jeton d'accès et les
informations de session du dispositif passager.
Le PVIS maître ou l'agent PVIS vérifie la validité de chaque message de demande avant de le
traiter. Si le message est valide, le passager est autorisé à contrôler le dispositif PVIS. Lorsque
le passager cesse d'utiliser le service, le PVIS maître ou l'agent PVIS initialise le dispositif et
le rend disponible pour les autres passagers.
5.7 Fonction de gestion de contenu
La fonction de gestion de contenu permet aux passagers d'accéder en toute transparence à
une variété de contenus fournis par différents fournisseurs de contenu et d'améliorer leur
expérience de voyage. Cette fonction comprend trois sous-fonctions essentielles: le
déploiement, la maintenance et la livraison.
– Déploiement: la sous-fonction de déploiement gère le processus d'envoi des métadonnées
associées et leur gestion par le biais de la fonction de gestion des profils lorsque de
nouveaux contenus sont disponibles auprès des fournisseurs de contenu préenregistrés.
De plus, cette sous-fonction gère les images de contenu afin d'assurer des services
optimaux aux passagers, en tenant compte des ressources disponibles et des
caractéristiques distinctes telles que le type et la taille de l'image.
– Maintenance: le contenu déployé peut ne plus être pris en charge ou avoir différentes
versions au fil du temps. Pour maintenir des services de haute qualité, il est nécessaire que
les métadonnées de contenu soient constamment à jour. Par conséquent, la sous-fonc

INTRODUCTION
It is noted that the markets and industries on infotainment services for vehicles (known as in-
vehicle infotainment services) have been growing rapidly. It is envisioned that a variety of
infotainment (or multimedia) devices and services will be newly developed for personal and
public vehicles in the future. Such devices include navigations, cameras, speakers, headrest
displays, air-conditioners, thermometers and heated seats, and lights.
A set of standards have so far been developed on configurable car infotainment services (CCIS)
with the IEC 63246 series. However, the CCIS standards have been basically designed for
personal users, such as car owners. In the meantime, there is also a crucial need to provide a
variety of infotainment services for public vehicles (PVIS) such as bus or train.
PVIS services have different requirements and features from CCIS services. For user type,
CCIS is targeted for one or two users (such as car owner), whereas PVIS are for a large number
of guests or passengers within the public vehicle. For device type, CCIS deals with the personal
devices (property or belonging) in the car, whereas PVIS will be targeted for a variety of public
devices that are contained in a public vehicle. Some PVIS services can be provisioned by
interworking with the external networks, as shown in the bus information service. For service
duration, CCIS usually provide long-term services, whereas PVIS can provide short-term
service during which a guest stays within a public vehicle.
From these observations, it is noted that there are many different features and requirements
between CCIS and PVIS. Accordingly, there is a need for standardization on PVIS. In particular,
PVIS will employ a set of agents to effectively manage a large number of users or devices.
The PVIS series (IEC 63479) describes infotainment (multimedia) services for terrestrial public
vehicles, such as bus, train, or subway. It is not applicable to public vehicles, such as airplane
or ship. For this purpose, the following issues are addressed: 1) identify a variety of functional
requirements for provisioning of PVIS, 2) design the PVIS framework, based on the identified
requirements. The PVIS standards are expected to provide guidelines on PVIS services for a
large number of users/devices, and to encourage development of new (enhanced) PVIS
services (possibly by interworking with the external systems).
The IEC 63479 consists of the following parts:
– Part 1: General
– Part 2: Requirements
– Part 3: Framework
IEC TR 63479-1 describes general considerations and system model for PVIS, with some
examples of PVIS services.
IEC 63479-2 describes the functional requirements for PVIS.
IEC 63479-3 describes the framework, including the functional information flows between
functional entities.

4 Overview
PVIS consist of a diverse ecosystem of entities, each contributing to the system's operation and
functionality. These entities can be categorized into two main groups:
– PVIS support entities: these entities are responsible for supporting the core functions
required by the PVIS. They include the PVIS master, PVIS agent, and PVIS devices. The
PVIS master serves as the central command, controlling and coordinating activities within
the system. The PVIS agent facilitates the connection between the master and the devices,
while the PVIS devices deliver the actual infotainment content to the passengers.
– PVIS user entities: these entities engage with the PVIS system on a more transient basis.
They include passenger devices, content providers, and external applications. Passenger
devices enable users to interact with the system, content providers supply the infotainment
materials, and external applications offer additional functionalities to enhance the overall
user experience.
The PVIS framework defines the functions that the PVIS master, agent, and devices shall
support in order to manage infotainment services effectively and deliver them to passengers
seamlessly.
Figure 1 illustrates how each entity has a specific set of PVIS functions to ensure the smooth
operation of PVIS. It is noted in the figure that the PVIS master should be able to perform the
functions of the PVIS agent, and the PVIS agent includes the functions of the PVIS device.
Figure 1 – PVIS entities and functions
Figure 2 presents a reference architecture of the PVIS system, which includes the six core
functions and the three interworking functions. The core functions are specifically designed to
meet the functional requirements of each entity, while the interworking functions enable smooth
interaction between these entities. The details of these functions are described in Clause 5,
Clause 6 and Clause 7.

5 Reference model for core functions
5.1 General
The PVIS reference model for core functions comprises several functional modules that
facilitate efficient management and utilization of infotainment services. As illustrated in Figure 3,
PVIS encompass the following modules: authentication management, profile management,
device management, content management, connectivity management, and history management.
Figure 3 – PVIS reference model for core functions
5.2 Authentication management function
The authentication management function within PVIS is responsible for delivering customized
services to authenticated users by leveraging their registered information. This function consists
of two crucial subfunctions: certification and permission.
The certification subfunction ensures the identification of each entity within the system and
generates access tokens that grant specific privileges for a limited duration. These access
tokens shall be included in all exchanged messages by the entity, enabling secure and
authorized communication.
The permission subfunction is responsible for validating exchanged messages and governing
the permissions associated with devices and content. Different entities within the PVIS service
can have varying levels of permission to operate devices and access content. The validation
process relies on the access tokens issued by the certification module, ensuring that only
authorized entities can perform permitted actions.
5.3 Connectivity management function
In PVIS, the connectivity information associated with the various PVIS entities plays a crucial
role in delivering efficient and secure services. This connectivity information is represented by
connection and session data.
Within a PVIS system, all functional entities, except for the PVIS master, are required to register
either with the PVIS master or the PVIS agent. During this registration process, a session token
is assigned to each entity. This session token is then included in all subsequent communications,
enabling the PVIS to maintain session context and track entity activities. For instance, a session
for a PVIS device includes details about the device's current state and occupant. Similarly, a
session related to a passenger's device encapsulates information such as the specific PVIS
device being used and the content currently being accessed. This session information forms
the foundation for maintaining effective and personalized interactions within the PVIS.
Furthermore, it facilitates the verification of entity permissions, ensuring secure and authorized
interactions within the system.
A connection is established between two entities to facilitate the exchange of messages.
5.4 History management function
The history management function is an essential component of the PVIS framework,
responsible for recording, maintaining, and utilizing historical data related to the usage of
infotainment services. It plays a critical role in improving service quality, enabling personalized
experiences, and supporting decision-making processes.
The module for service usage analytics focuses on acquiring and managing key usage
information, such as the most frequently accessed types of services by users. This data serves
as a foundation for enhancing user convenience and enables functions like content
recommendation and service personalization. Additionally, this information can be shared with
content providers to improve their services.
Furthermore, the history management function oversees the management of system historical
log information. Log information is vital in diagnosing and resolving system errors within the
PVIS. By providing a comprehensive record of system activities and events, it facilitates timely
identification, analysis, and resolution of any issues, contributing to the stability and reliability
of the system.
5.5 Profile management function
Profile management function serves as a repository for storing and organizing pertinent details
associated with devices, agents, and content. These profiles encompass a range of information,
including device specifications, connectivity attributes, access permissions, preferences, and
historical usage data. By collecting and managing such information, PVIS can effectively adapt
its services to meet the specific needs and preferences of individual entities.
5.6 Device management function
In PVIS, device management involves registering devices with a PVIS master or PVIS agent.
The device management function comprises three subfunctions: provisioning, monitoring, and
control.
– Provisioning: the provisioning subfunction handles the configuration process when
registering a PVIS device. This includes assigning a unique identifier to the device, setting
up its network connections, and installing any necessary software. It also covers updating
or decommissioning devices as required.
– Monitoring: PVIS entities registered in the system should always have their latest status
accessible. This is achieved through the following operating procedures:
• Periodic status reporting: PVIS devices periodically send their status to the relevant
PVIS agent or PVIS master. This ensures continuous and controllable connection
between the entities through message exchange. By consistently reporting status, the
PVIS system maintains an up-to-date understanding of the device's status and its
surrounding environment, allowing for identification and pre-emption of potential issues.
• Status reporting on status change: when a status change is detected, the PVIS system
quickly prepares for unexpected situations.
• Querying status: The PVIS master or PVIS agent managing a PVIS device can request
the device's status at any time by sending a status report request. This is useful when a
passenger device requests the list of available devices or when an expected status
report is not received within a specific time threshold.
– Control: the device management function provides a list of available PVIS devices and
supports control operations for those devices. Passengers should obtain an access token
through the certification procedure to access this list. The request message should include
the access token and session information of the passenger device.
The PVIS master or PVIS agent verifies the validity of each request message before processing
it. If the message is valid, the passenger is allowed to control the PVIS device. When the
passenger stops using the service, the PVIS master or PVIS agent initializes the device and
makes it available for other passengers.
5.7 Content management function
The content management function enables passengers to seamlessly access and engage with
a range of content provided by different content providers, enhancing their travel experience.
This function comprises three critical subfunctions: deployment, maintenance, and delivery.
– Deployment: the deployment subfunction handles the process of dispatching associated
metadata and managing it through the profile management function when new content
becomes available from pre-registered content providers. Additionally, this subfunction
manages content images to ensure optimal services to passengers, considering available
resources and distinct characteristics such as image type and size.
– Maintenance: deployed content can become unsupported or have varying versions over
time. To maintain high-quality services, the content metadata needs to be consistently up-
to-date. Therefore, the maintenance subfunction regularly queries content providers to
refresh this information, eliminating outdated metadata and images. The content
management function ensures the ongoing maintenance of deployed content.
– Delivery: The delivery subfunction efficiently delivers content to passengers. While the PVIS
master manages all deployed content, the PVIS agent also supports content delivery to
distribute the load. The content management function recommends a content list based on
the passenger's information and the PVIS device in use, and delivers the content to the
PVIS device according to the passenger's request. When receiving a content delivery
request, the PVIS agent downloads the content from either the PVIS master or content
provider, delivers it to the PVIS device, and temporarily stores the content to enhance the
passenger experience.
6 Reference model for interworking functions
6.1 General
The PVIS reference interworking model defines the functions that are used to communicate with
a PVIS system. Figure 4 shows the interworking functions, which consists of transport function,
message function, and interface function.
Figure 4 – PVIS reference model for interworking functions
6.2 Transport function
The transport function of the interworking function oversees the transfer of data between two
PVIS entities. The communication within PVIS is facilitated through three different message
types: report, notification, and request. Each type has distinct characteristics and a particular
process.
– Report messages serve the purpose of exchanging frequently occurring, low-criticality
information such as device status reports. Each report message is processed independently,
ensuring an uninterrupted flow of regular updates within the system.
– Notification messages signal specific events, like a change in a device's status. As they rely
on a persistent connection between the sender and receiver, they offer a high level of
reliability throughout the duration of the connection. To ensure delivery, each notification
message carries a unique message identifier and, upon successful receipt, an
acknowledgment message is sent by the receiving entity's message function.
– Request messages within the PVIS serve the purpose of seeking specific data or prompting
certain actions, such as requisitioning a content list. Each request message is designed to
generate a corresponding response. The transport function is tasked with forwarding the
received requests to the core function. If a response is not forthcoming within a designated
threshold, an error message is dispatched. In addition, the transport function should ensure
the reliable delivery of both the request and the response message it sends with
retransmission mechanism.
6.3 Message function
The message function is responsible for formatting and sending messages between PVIS
entities. Messages are used to exchange data, such as profile, status, command, and content.
– Representation: the message function in the PVIS converts data from core functions into a
standardized message format and verifies the format of received messages. Ensuring
uniform representation of messages across all entities is vital for common comprehension
and effective communication within the PVIS framework. Each message is composed of two
primary parts: a header, encapsulating metadata specific to the message, and a payload,
which houses the data pertinent to the message's purpose.
The message header comprises fields of predetermined lengths, encapsulating key
information such as the message type, length, and a unique identifier. This ensures an
organized and standardized format for all messages, promoting efficient processing and
interpretation.
On the other hand, the message payload contains a diverse range of data types, from text-
based data like content lists and device statuses, to binary data for content. Accompanying
this data is information specifying the data's representation format. Popular multipurpose
internet mail extensions (MIME) types can be employed to signify the data representation.
– Argument: various types and categories of messages necessitate specific arguments within
the PVIS framework. For instance, a notification message requires a unique message
identifier used to ensure delivery, while a request message necessitates a token
corresponding to the response and session information for authorization checks.
The message function manages this complexity by verifying that the necessary arguments
are included, tailored to the type and nature of each message. This guarantees proper
structure and context for every message, enhancing the effectiveness and reliability of
communication within the system.
6.4 Interface function
The interface function within the PVIS framework plays a crucial role in filtering messages based
on pre-defined policies or rules. This function oversees both network and application interfaces,
ensuring efficient and secure communication.
The PVIS infrastructure utilizes two distinct networks: the in-vehicle network and the external
network. It is worth noting that communications via the external network can request additional
firewall rules to bolster security compared to the internal in-vehicle network.
The interface function allows PVIS to implement differentiated policies for each network,
ensuring messages align with respective rules. This targeted approach not only elevates the
system's security but also tailors message processing to each network's unique needs and
characteristics, enhancing the efficiency and security of PVIS operations.
Furthermore, the interface function enables the definition of application-level interfaces,
facilitating appropriate message processing. This empowers PVIS's core functions to provide
selective functionality and information, ensuring a robust service provision.
7 Information flows for functional operations
7.1 General
Clause 7 shows the information flows for the typical service scenarios of PVIS. These
information flows illustrate how information and operational steps of core functions are
exchanged and performed through the interaction abilities of each PVIS entity.
7.2 Device provisioning
A PVIS device shall be provisioned by the PVIS master or PVIS agent before it can operate.
Figure 5 shows how the information is exchanged for PVIS device provisioning.
a) Before the registration of a new PVIS device can commence, the PVIS administrator shall
prepare a configuration profile for initializing and setting up the device. This profile contains
essential software and firmware updates, as well as information about the vehicle type and
network environment in which the device will operate. The necessary data for this process
will be collected from external applications such as device providers or administrators. The
tasks associated with this process are performed by the following core functions:
1) Device subfunction of profile management function provides an interface for creating
and updating the PVIS device configuration profile and stores and manages the created
profile.
2) Log subfunction of history management function records the log of the creation of the
new profile.
b) The PVIS device requests registration with the nearby PVIS master or PVIS agent, and upon
receiving the request, the PVIS master or agent checks the possibility of registration and
responds with a message containing information necessary for initialization and
authentication. These tasks are performed by the following core functions:
1) Permission subfunction of authentication management function confirms whether the
request message from the PVIS device has been sent by an authorized device.
Registration of a PVIS device should be carried out by a user with administrator-level
permissions, and the registration request message must include an authentication key
from an authorized user.
2) Provisioning subfunction of device management function performs initialization of the
PVIS device based on the configuration profile and registers the PVIS device.
3) Device subfunction of profile management function stores the profile of the registered
PVIS device.
4) Certification subfunction of authentication management function generates a unique
authentication key to identify and authenticate the registered PVIS device.
5) Log subfunction of history management function records the log of the registration of the
PVIS device.
c) The PVIS master regularly checks whether the registered PVIS devices require updates to
ensure they operate at optimal performance and acquires the necessary update information.
These tasks are performed by the following core functions:
1) Device subfunction of profile management function periodically checks with the external
application for updates and, if there are updates, downloads the new configuration profile.
2) Log subfunction of history management function records the log of the configuration
profile update.
d) The PVIS master notifies PVIS devices that require updates, ensuring they are aware and
prepared for the new updates. This task is performed by the following core functions:
1) Control subfunction of device management function delivers notifications to the PVIS
devices that require updates.
e) PVIS devices that are ready for an update request the updated configuration profile from
the PVIS master. The device then performs the necessary updates based on this profile.
These tasks are performed by the following core functions:
1) Provisioning subfunction of device management function executes the update of the
PVIS device based on the new configuration profile.
2) Device subfunction of profile management function stores the updated profile of the PVIS
device.
3) Log subfunction of history management function records the update log of the PVIS
device profile.

7.3 Device monitoring
Device monitoring is a crucial operation of the PVIS, ensuring the continuous and reliable
operation of the system. This process involves the surveillance and analysis of PVIS device
health, activity, and performance within the PVIS.
Figure 7 shows how the information is exchanged for PVIS device monitoring.
Figure 7 – Information flow for PVIS device monitoring
a) PVIS devices maintain a connection with the PVIS master or agent and periodically send
status report messages to keep them informed of their current state. Similarly, the PVIS
agent regularly sends status report messages to the PVIS master. These tasks are executed
by the following core functions:
1) Monitoring subfunction of device management function periodically generates status
report messages that include status information of the PVIS device and transmits them
to the PVIS master or agent where the PVIS device is registered.
2) Connection subfunction of connectivity management function carries out regular
message exchanges to maintain the connection between the PVIS device and the PVIS
master or agent. If no message is received from the PVIS device within a certain
timeframe, the connection is considered lost, thus the connection subfunction resets the
disconnection timer whenever a status report message is exchanged.
b) If the PVIS master or agent does not receive a status report message after the set interval
following the most recent status report message, it transmits a status report unreachable
notification. This task is executed by the following core functions:
1) Monitoring subfunction of device management function generates and sends a status
report unreachable notification if there is no status report message from the PVIS device
for a certain amount of time.
c) Upon receiving this notification, the PVIS device or agent immediately sends a message for
status reporting. The core functions for this task are the same as in the first step.
d) When the status of PVIS device is changed, the PVIS device sends a status change report
message immediately to PVIS master through the PVIS agent. This task is executed by the
following core functions:
1) Monitoring subfunction of device management function generates and sends a status
report unreachable notification if there is no status report message from the PVIS device
for a certain amount of time.
2) Device subfunction of profile management function updates the PVIS device’s profile
based on the information contained in the status report message.
3) Connection subfunction of connectivity management function this subfunction resets the
disconnection timer when a status changed report is exchanged.
4) Log subfunction of history management function records the log of the PVIS device
profile update.
Figure 8 illustrates the PVIS core functions corresponding to the information flow.
Figure 8 – PVIS core functions for PVIS device monitoring
7.4 Device control
Within PVIS, the device control operation is integral to providing passengers with an interface
through which they can interact with a range of infotainment services. This operation focuses
on ensuring that the infotainment terminals, which passengers use to access content, are
responsive, customizable, and secure.
Figure 9 shows how the information is exchanged for PVIS device control.
a) Passengers intending to utilize the services offered by PVIS begin by requesting registration
with the PVIS master. In response, the PVIS master generates an authentication key for
verifying the passenger and a session to manage the passenger's service context. These
tasks are performed by the following core functions:
1) Certification subfunction of authentication management function checks the request by
verifying details such as the passenger ID and seat number. Based on this information,
it generates an authentication key for the duration of the service use, ensuring
passenger verification.
2) Session subfunction of connectivity management function creates a session for the
authenticated passenger. The session is used to manage interactions with PVIS, track
service usage, and provide an improved and personalized service. If the passenger
discontinues the service, the session subfunction ensures all related information is
cleared to maintain security and privacy.
3) Log subfunction of history management function records the registration logs of the
passenger.
b) Once verified, the passenger requests a list of available PVIS devices from the PVIS master,
which responds with the list. This task is performed by the following core functions:
1) Permission subfunction of authentication management function verifies that the request,
based on the passenger's authentication key, has been transmitted by an authorized
user and is appropriate for the user's permissions.
2) Device subfunction of profile management function generates a list of PVIS devices
