1 Scope
The present document 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.
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.
The present document does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the
appropriate Global System for Mobile communications (GSM) specifications.
The present document 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 the present document.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and 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
8
number of group Ids and group call areas shall be 10 , 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 MSISDN or ISDN 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 may be none,
one or more dispatchers involved in a particular voice broadcast call.
As a mandatory network requirement, configuration of up to 5 dispatchers shall be supported. Optionally, up to a
maximum of 20 dispatchers may be configured for a particular group call reference.
Destination service subscriber: Service subscriber to which the VBS call is directed.
Calling service subscriber: Service subscriber which originates the VBS call.
Calling dispatcher: Dispatcher which originates the VBS call.
Destination dispatcher: Pre-registered dispatcher to which the VBS call is directed.
Destination subscriber: Destination dispatcher(s) and/ or destination service subscriber(s) to which the VGCS call is
directed.
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
8
group Ids defined in this PLMN. The maximum number of group Ids and group call areas combined shall be 10 , 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.
Originator-to-dispatcher information: Information sent by the service subscriber originating a voice group call to the
network during call setup for distribution to the dispatchers to be attached to the group call during call setup.
Listener: see Listening service subscriber
Listening service subscriber: Service subscriber who is listening to an ongoing voice group call.

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 service subscriber or calling dispatcher to send speech unidirectional and
simultaneously to all entitled dispatchers and to destination service subscribers belonging to a predefined group
call area who have a subscription to the applicable group ID.
b) The calling service 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. The calling dispatcher may be any dispatcher who
is entitled to originate VBS calls to the related call reference.
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 cells. Group
call areas shall be predefined in the network by the service provider, co-ordinated by the network operator.
In case of a calling service subscriber initiating a VBS call, the group call area is uniquely identified by the
actual cell in which the service subscriber resides at the moment of VBS call initialization and by the called
group ID.
A calling dispatcher initiating a VBS call will be connected to a related predefined group call area. The
entitlement of the dispatcher is checked by the network element responsible for the voice broadcast call
management by verification of the calling identity. Since a dispatcher may be registered to mo
