(Main)Digital cellular telecommunications system (Phase 2+) (GSM); Technical realization of Supplementary Services (GSM 03.11 version 7.0.1 Release 1998)
- Abstract
This ETS describes the general aspects on how supplementary services in the GSM system are realized from a technical point of view. Description of technical realization for specific supplementary services can be found in GSM 03.8x and 03.9x-series technical specifications. All supplementary services may require signalling on the radio path. Signalling procedures and messages used are defined in the GSM 04.8x and 04.9x-series of technical specifications. For some supplementary services information needs to be transferred between the home location register (HLR), the visitor location register (VLR) and the mobile services switching centre (MSC). Signalling procedures for such information transfer are defined in technical specification GSM 09.02. Definitions and descriptions of supplementary services are given in the GSM 02.8x and 02.9x-series of technical specifications. Definitions are given in technical specification GSM 02.04. NOTE: The technical specifications on the technical realization of supplementary services do not distinguish between subscriber, user and customer, since all three do not fully cover the textual needs. Generally the term subscriber is used, even if this person is not having the subscription.

SIST EN 300 928 V7.0.1:2003 is the Slovenian adoption of ETSI EN 300 928 V7.0.1 for GSM supplementary services. It describes the technical realization of supplementary services in the digital cellular telecommunications system (Phase 2+) and is mainly about how the network, HLR, VLR, MSC and mobile station handle service state, signalling and password-controlled operations.
What does SIST EN 300 928 V7.0.1:2003 specify?
SIST EN 300 928 V7.0.1:2003 specifies the general technical realization of supplementary services in GSM. It gives the common handling rules that apply across services, while the detailed behaviour of individual services is left to the GSM 03.8x and 03.9x series.
The document covers signalling on the radio path, information transfer between HLR, VLR and MSC, and the way supplementary service state is represented and exchanged. It is organized into clause 1 references and abbreviations, clause 2 service state and basic service group handling, clause 3 password handling, clause 4 supplementary service data management, clause 5 the description format, and Annex A on change request history.
What are the key requirements of SIST EN 300 928 V7.0.1:2003?
SIST EN 300 928 V7.0.1:2003 defines the common procedures for activation, deactivation, registration, erasure, interrogation and invocation. In practice, this means implementers must follow the service-specific GSM 03.8x and 03.9x rules, but use the shared handling model in this document.
Service state handling
The standard introduces a state vector made up of ProvisioningState, RegistrationState, ActivationState and HLRInductionState. This matters because the network uses these logical states to decide whether a supplementary service can be invoked and how its status is reported.
SS-Status coding and use
Clause 2.1.2.1 defines how the HLR encodes service state into SS-Status using the P, R, A and Q bits. The VLR must store enough information to support invocation, interrogation and notifications, and when it returns SS-Status it passes through the same bit values it received from the HLR.
Invocation rules at HLR, VLR and MS
At the HLR, a service can be invoked only when its ActivationState is Active and Operative. At the VLR, invocation depends on the A and Q bits, with A=1 and Q=0 required. The MS is guided to interpret P, R, A and Q together, which helps terminals display the right service state to the user.
Basic service group processing
Clause 2.2 requires requests for registration, erasure, activation, deactivation or interrogation to refer to a basic service group (BSG). The destination entity splits a BSG into elementary basic service groups (EBSG) when needed, ignores EBSGs that are not provisioned or not applicable, and returns general, partial or complete responses according to what was accepted.
Exceptional handling of basic service codes
Clause 2.3 says that if an MS sends an individual teleservice code or bearer service code instead of an EBSG, the network treats it as the corresponding EBSG. This avoids rejecting requests just because the terminal used a more specific service code.
Password handling for protected supplementary services
Clause 3 defines password-controlled supplementary services. The HLR stores the password and the Wrong Password Attempts counter (WPA), checks the password on protected operations, and changes the subscriber’s control option to service-provider control after too many failed attempts. For operators, this is the core rule set for protecting sensitive service changes.
Provisioning-related data handling
Clause 4 states that for supplementary services activated as a result of provision, the HLR sends Provisioned and Active indicators to the VLR and to the MS when interrogated. That gives consistent network and terminal views of services that become active when provisioned.
What terms does SIST EN 300 928 V7.0.1:2003 define?
- Home Location Register (HLR) - The master network database for subscriber service state and related supplementary service data.
- Visitor Location Register (VLR) - The serving location register that stores enough service information for local invocation, interrogation and notifications.
- Mobile services Switching Centre (MSC) - The switching node that handles supplementary service procedures together with the location registers.
- SS-Status - A four-bit status parameter used to carry provisioning, registration, activation and quiescent/operative state information.
- Basic service group (BSG) - The basic service set a supplementary service request refers to.
- Elementary basic service group (EBSG) - The finer-grained basic service unit used for separate handling of requests.
- Wrong Password Attempts (WPA) - The counter in the HLR that tracks repeated incorrect password entries.
Who uses SIST EN 300 928 V7.0.1:2003?
Telecom engineers use this standard when implementing supplementary service behaviour in GSM network nodes and mobile stations. It is also used by HLR, VLR and MSC implementers, protocol testers, service designers and quality teams that need to verify service state handling, call-independent supplementary service procedures and password-controlled service operation.
What changed in SIST EN 300 928 V7.0.1:2003 from the previous edition?
SIST EN 300 928 V7.0.1:2003 is identified as GSM 03.11 version 7.0.1 for Release 1998, and the foreword says that version 7.x.y uses the x digit for substantive changes and the y digit for editorial changes. Annex A provides the change request history leading up to version 7.0.1.

What does the SIST EN 300 928 V7.0.1:2003 document contain?
The document contains the shared GSM rules for supplementary service state, SS-Status encoding, call-independent request handling, and password-controlled operations. It also includes process figures for request handling and password control, including the service state model and the decision flows used by the HLR and VLR.
Clause 5 defines the structure used to describe individual supplementary services in the companion specifications: functions and information flows, information stored in the HLR, information stored in the VLR, and handover. Annex A gives the change request history for the technical specification.
