Overview

SIST ETS 300 926 E1:2003 is a European Telecommunication Standard developed by the Slovenski inštitut za standardizacijo (SIST). It provides the stage one description for the Voice Broadcast Service (VBS) in the digital cellular telecommunications system (GSM Phase 2+), outlining the service from the user and subscriber perspective. The standard defines how a service subscriber can distribute speech or compatible signals to all or a specific group of subscribers within a predefined geographical area.

VBS plays a key role in public mobile networks, enabling efficient and simultaneous delivery of voice broadcasts to multiple recipients. The service is essential for group communication, particularly in situations where rapid dissemination of information to a designated set of users is required.

Key Topics

• Service Scope: VBS allows a subscribed user or dispatcher to transmit a voice message across a defined group call area, reaching all subscribers associated with a particular group ID in that area.
• Group IDs and Areas: The concept of group IDs classifies subscribers and defines the target audience in each group call area, which may consist of several GSM network cells.
• User Roles:
  • Service Subscriber: Individual mobile users authorized to receive or initiate VBS calls depending on their subscription.
  • Dispatcher: Predefined fixed or mobile users with wider privileges, such as initiating VBS calls across multiple group IDs or areas.
• Call Establishment and Notifications: VBS calls are initiated via specific addressing methods. Notifications are broadcast to all target group members, and dispatchers are alerted individually.
• Mobility Management: The service supports changes in subscriber location, automatically adding or removing users from a broadcast session as they move in or out of the group call area.
• Priority and Pre-emption: Different levels of call priority and pre-emption are supported, coordinated with services like enhanced Multi-Level Precedence and Pre-emption (eMLPP).
• Interoperability with GSM Features: VBS interacts with several GSM supplementary services such as Call Barring, Call Hold, Call Forwarding, and Calling Line Identification. However, integration specifics vary depending on user role and broadcast scenario.

Applications

• Public Safety and Emergency Communications: VBS is crucial for rapidly informing first responders, emergency teams, or the public during critical incidents.
• Industrial and Transportation Sectors: The service can support coordinated operations in sectors like railways, utilities, and logistics by broadcasting instructions or warnings across teams.
• Group Coordination: Enterprises, government agencies, and service operators can leverage VBS for efficient communication during planned events, maintenance, or crisis management.
• Roaming Support: VBS extends functionality for users traveling outside their home network with dedicated supra-PLMN group IDs, enabling seamless voice broadcasts across networks with appropriate coordination.

Related Standards

• GSM 02.67: Defines the enhanced Multi-Level Precedence and Pre-emption service (eMLPP), relevant for prioritizing calls within VBS.
• GSM 01.04 (ETR 350): Offers standard abbreviations and acronyms used in GSM networks, including those referenced in VBS.
• GSM 02.40: Outlines procedures for call progress indications, serving as a reference for handling VBS call notifications and failures.
• GSM 12.05 (ETS 300 616): Specifies event and call data requirements, including charging and data logging for VBS calls.

1 Scope
This European Telecommunication Standard (ETS) specifies the stage one description of the Voice
Broadcast Service (VBS) which allows the distribution of speech (or other signals which can be
transmitted via the speech codec), generated by a service subscriber, into a predefined geographical area
to all or a group of service subscribers located in this area.
[Remark: A similar service might be provided for the distribution of data messages. This service is not
treated in the present stage 1 description. However, the principle requirements and realizations should be
co-ordinated and synergies with the respective work item on General Packet Radio Service (GPRS)
regarded.]
The Voice Broadcast Service (VBS) is applicable to all mobile stations in a certain network and area which
have the technical capability and the respective subscription to receive a VBS call.
NOTE: It is not considered as requirement that normal GSM phase 2 mobile stations will be
able to be used for this service.
The service is described from the service subscriber's and user's point of view; in particular:
- the procedure for normal operation with successful outcome;
- the action to be taken in exceptional circumstances;
- the interaction with other GSM services and features.
This ETS does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the
appropriate Global System for Mobile communications (GSM) specifications.
This ETS defines a teleservice of the digital cellular telecommunication system GSM. Any interaction with
other services and/or networks not dealt within clauses 8 or 9 are outside the scope of this ETS.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
network operator: Entity which provides the network operating elements and resources for the execution
of the VBS.
service provider: Entity which offers the VBS for subscription. 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 the term "VBS call".
group identification (group ID): A numerical classification. The maximum number of group IDs which
can be defined in one PLMN depends on the maximum number of group call areas defined in this PLMN.
The maximum number of group IDs and group call areas shall be 10 -1, 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 shall receive all voice broadcast calls to a certain group ID in a group call area (this shall be
done automatically by the network). 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 broadcast calls, they shall call a particular MSISDN number which is related to a group
ID and group call area. Dispatchers using 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 be none 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 of group IDs defined in this PLMN. The maximum number of group IDs and group
call areas shall be 10 -1, The composition of a group call area is predefined in the network by the service
provider. Changing of cell allocations in the network due to operational reasons will need an adaptation of
the group call area definition. The group call area may include cells of more then one MSC area and cells
of more than one PLMN.

4 Description
The VBS is defined in the following. Figure 1 gives an explanation of the logical concept of the VBS.
a) The VBS enables a calling subscriber to send speech unidirectional and simultaneously to all
entitled dispatchers and to destination subscribers belonging to a predefined group call area who
have a subscription to the applicable group ID.
[Remark: calls with the possibilities of semi-duplex conversation between the service subscribers
involved are not subject to the VBS but are treated in an additional stage 1 description on Voice
Group Call Service (VGCS).]
b) The calling subscriber may be any service subscriber which has subscribed to the related group ID
and is entitled to establish a voice broadcast call by his subscription or any dispatcher who is
entitled for it by his identity which shall be registered in the network.
The destination subscriber may be any service subscriber which has subscribed to the related
group ID or any dispatcher who is entitled for it by his identity which is registered in the network.
c) The broadcast call shall be established in a group call area which is comprised of one or a cluster of
