1 Scope
®
The present document is part of the MirrorLink specification which specifies an interface for enabling remote user
interaction of a mobile device via another device. The present document is written having a vehicle head-unit to interact
with the mobile device in mind, but it will similarly apply for other devices, which provide a colour display, audio
input/output and user input mechanisms.
The TmNotificationServer service is an UPnP service that allows control points to receive diverse notifications from the
devices that support the TmNotificationServer service.
The TmNotificationServer service enables the following features to:
• send a notification to the head unit;
• get an action described in the notification.

4 Service Modeling Definition
4.1 Service Type
The following service type identifies a service that is compliant with the present document:
urn:schemas-upnp-org:service:TmNotificationServer:1
TmNotificationServer defined in the present document refers to the same service type. The TmNotificationServer service
shall follow defined UPnP behaviour within the UPnP Device Architecture 1.1 [1].
4.2 TmNotificationServer Service Architecture
This service provides the features for a MirrorLink UPnP Control Point to receive notifications from a MirrorLink
UPnP Server Device.
Based on information of the notification evented to the MirrorLink UPnP Control Point, the MirrorLink UPnP Control
Point may launch the applications to bring it to foreground on the MirrorLink Server or may create its own native user
interface. In both cases, this does allow the end-user to act on the given notification.

X = Non-standard.

4.3.2 ActiveNotiEvent
ActiveNotiEvent is an evented state variable of type A_ARG_TYPE_NotiID, which contains the most urgent notification
that needs to be handled from the MirrorLink UPnP Control Point. ActiveNotiEvent shall originate from an application
(as given in appID), which has been set using the SetAllowedApplications actions.
It is the responsibility of the MirrorLink UPnP Server to decide on the most urgent notification.
If a notification event A gets overloaded by another notification event B, the notification event A may become
pending again, once notification event B is cleared and A is still pending. In that case the MirrorLink UPnP
Server shall again provide an event update for the notification event A.
If the state variable is an empty string, no notification is available on the MirrorLink UPnP Server to be handled from
the MirrorLink UPnP Control Point.
On receiving an AcitveNotiEvent event, the MirrorLink UPnP Control Point can query specific notification by invoking
the GetNotication action. The MirrorLink Client shall immediately respond to an incoming notification, unless safety
related or other higher priority tasks currently require the user's attention. Notifications from unsupported applications
shall be immediately cleared, sending an InvokeNotiAction with ActionID set to "0x00".
Implementation Note:
A MirrorLink 1.1 Client may not immediately respond to an incoming notification.
The MirrorLink UPnP Server shall clear the active notification if the MirrorLink UPnP Control Point has responded to
the notification by either using the InvokeNotiAction action or by launching the respective application using
TmApplicationServer:1 service LaunchApplication action. The MirrorLink UPnP Server shall clear the active
notification if the notification is not available on the MirrorLink UPnP Server anymore.
When the event is issued the first time, the ActiveNotiEvent value shall contain either a single value of type
A_ARG_TYPE_NotiID, in case a notification is available, or of an empty string, in case no notification is available.
4.3.3 NotiAppListUpdate
NotiAppListUpdate is an evented state variable of type A_ARG_TYPE_String, which contains a comma separated list of
applications identifiers of applications, supporting notifications. Each application identifier is of type
A_ARG_TYPE_AppID.
The state variable is evented, implying that clients can subscribe to receive notifications every time the variable changes
using UPnP standardized eventing mechanisms. It is important to note that this variable only contains the application
identifiers of those applications, whose entries in supported applications list have changed since the last time an event
notification was sent out (i.e. applications which either have added or removed notification support).
On receiving a NotiAppListUpdate event, a MirrorLink UPnP Control Point can retrieve the supported application list
by invoking the GetSupportedApplications action, to validate, whether an application has removed or added notification
support.
NotiAppListUpdate value shall consist of a comma separated list of all application identifiers from applications
supporting notification, when the event is issued by the TmNotificationServer service for the first time.
