Overview

SIST EN 300 926 V6.0.1:2003 defines the Voice Broadcast Service (VBS) for the digital cellular telecommunications system (GSM Phase 2+), in alignment with GSM 02.69 version 6.0.1, Release 1997. This European Standard, adopted by the Slovenski inštitut za standardizacijo (SIST), outlines the functional stage 1 service description for VBS, which enables the distribution of speech or compatible signals from a single subscriber to a predefined group of users within a specified geographical area.

The standard specifies how the VBS operates within the GSM infrastructure, its interactions with other GSM services and network features, as well as service provisioning, configuration, and withdrawal. The upgrade it details transitions the service from previous GSM Phase 2+ implementations to the requirements and enhancements specified for Release 1997, contributing to improved group communication capabilities in GSM networks.

Keywords: Digital cellular telecommunications, GSM, Voice Broadcast Service, VBS, telecommunications standard, group communication, mobile network, GSM Phase 2+, Release 1997.

Key Topics

• Voice Broadcast Service (VBS):
  VBS allows a subscriber (service subscriber or dispatcher) to initiate a unidirectional voice call to all group members within a designated area. This is useful for scenarios such as public safety, railway communications, and other group-oriented applications.

• Service Subscription and Group Management:

  • Subscribers can be assigned up to 50 group IDs.
  • Group call areas are predefined by the network provider and linked with group IDs.
  • Dispatchers can be assigned special roles, including initiating and receiving group calls.

• Call Establishment and Operation:

  • Calls are established automatically when a subscriber or dispatcher initiates a VBS call by dialing a specific short code or address.
  • Notification and paging mechanisms are used to alert all eligible group members without paging individual subscribers.

• Interaction with GSM Services and Features:
  VBS interacts with a wide range of GSM services (e.g., call forwarding, caller line identification, barring, and eMLPP for prioritization). The standard details how these services are applied or restricted during broadcast calls.

• Roaming and Inter-network Coordination:
  The VBS supports roaming by allowing "supra-PLMN" group IDs, coordinated across multiple network operators.

Applications

The Voice Broadcast Service (VBS) offers significant practical value for organizations and users requiring efficient group communications over GSM networks. Key use cases include:

• Public Safety and Emergency Services:
  Enables emergency services, such as police, fire departments, and railway operators, to broadcast critical voice messages to teams spread across large geographical areas, supporting rapid response and coordination.

• Railway and Transportation:
  Facilitates communication among train drivers, dispatchers, and operational staff to enhance safety and operational efficiency.

• Enterprise and Industrial Communications:
  Suitable for large organizations needing to convey information quickly to multiple teams or units, such as in utilities, logistics, or field operations.

• Roaming Support:
  Enables subscribers to participate in group calls even when outside their home network, so long as group IDs are coordinated.

The flexibility and scalability provided by VBS, paired with its integration in the global GSM ecosystem, make it an essential service for critical communications and group broadcasting needs.

  Digital cellular telecommunications system (Phase 2+); Abbreviations and acronyms.

• GSM 02.67:
  Digital cellular telecommunications system (Phase 2+); enhanced Multi-Level Precedence and Pre-emption service (eMLPP) - Stage 1.

• GSM 12.05:
  Digital cellular telecommunications system (Phase 2); Subscriber related event and call data.

• ETSI EN 300 926 (all versions):
  Defines requirements for VBS service in different GSM releases.

Organizations implementing VBS should ensure compliance with these and other relevant telecommunications standards to guarantee interoperability, security, and service efficiency within GSM networks. For more comprehensive technical specifications, cross-reference with the relevant release documents and guidelines from ETSI and GSM standardization bodies.

The network operator may be the service provider.service subscriber: Mobile subscriber which subscribes to the VBS.voice broadcast call: An instance of the VBS initiated by a VBS subscriber. This term is used synonymously with theterm "VBS call".group identification (group ID): A numerical classification. The maximum number of group IDs which can be definedin one PLMN depends on the maximum number of group call areas defined in this PLMN. The maximum number ofgroup IDs and group call areas shall be 108, Service subscriber shall be provided with one or up to 50 group IDs.dispatcher: Particular fixed line or mobile users are identified within the network as dispatchers. Dispatchers shallreceive all voice broadcast calls to a certain group ID in a group call area (this shall be done automatically by thenetwork). In addition they can initiate voice broadcast calls to a group ID in a group call area.Dispatchers shall be connected to a voice broadcast call by means of standard links via radio or via an ISDN.They shall be called by their ISDN or MSISDN number, respectively. When dispatchers initiate voice broadcastcalls, they shall call a particular MSISDN number which is related to a group ID and group call area. Dispatchersusing the GSM network can be located outside of this group call area.The identities of the dispatchers are exclusively predefined in the network by the service provider. There will benone or up to five dispatchers involved in a particular voice broadcast call.destination subscriber: Service subscriber or dispatcher to which the VBS call is directed.calling subscriber: Service subscriber or dispatcher which invokes the VBS call.group call area: Predefined area composed of one or a cluster of cells, to which a particular VBS call is distributed.The maximum number of group call area IDs which can be defined in one PLMN depends on the maximum number ofgroup IDs defined in this PLMN. The maximum number of group IDs and group call areas combined shall be 108, Thecomposition of a group call area is predefined in the network by the service provider. Changing of cell allocations in thenetwork due to operational reasons will need an adaptation of the group call area definition. The group call area mayinclude cells of more then one MSC area and cells of more than one PLMN.3.2AbbreviationsAbbreviations used in the present document are listed in GSM 01.04.4DescriptionThe VBS is defined in the following.
