ETSI ETSI TS 100 925 V8.2.1 (2005-07) 5 3GPP TS 02.68 version 8.2.1 Release 1999 1 Scope The present document specifies the stage one description of the Voice Group Call Se
22、rvice (VGCS) which allows speech conversation of a predefined group of service subscribers in half duplex mode on the radio link taking into account multiple mobile service subscribers involved in the VGCS call per cell. The VGCS is applicable to all mobile stations in a certain network and area whi
23、ch have the technical capability and the corresponding subscription, respectively, to participate in a VGCS 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 subscribers and use
24、rs 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 make
25、s reference to the appropriate Global System for Mobile Communications (GSM) specifications. The present document defines a teleservice of the digital cellular telecommunications system GSM. Any interaction with other services and/or networks not dealt with in clauses 7 or 8 are outside the scope of
26、 the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

29、 Release 1999 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 VGCS. Service provider: Entity which offers
30、 the VGCS for subscription. The network operator may be the service provider. Voice group call: An instance of the VGCS initiated by a subscriber. This term is used synonymously with the term “VGCS call“. Service subscriber: Mobile subscriber which subscribes to the VGCS. Group identification (group
31、 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 combined is 108, Service subscriber shall be provided with one or up to 50 g
32、roup IDs. Dispatcher: Particular fixed line or mobile users are identified within the network as dispatchers. Dispatchers shall receive all voice group 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 group calls
33、to a group ID in a group call area. Dispatchers shall be connected to a voice group 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 group calls, they shall call a particular MSISDN number whi
34、ch 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 particula
35、r voice group call. Destination service subscriber: Service subscriber to which the VGCS call is directed. Calling service subscriber: Service subscriber which originates the VGCS call. Calling dispatcher: dispatcher which originates the VGCS call. Destination dispatcher: Pre-registered dispatcher t
36、o which the VGCS 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 VGCS call is distributed. The maximum number
37、 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 combined is 108, The composition of a group call area is predefined in the network by the service provider. Changing of cell
38、allocation in the network due to operational reasons will need an adaptation of the group call area definition. The group call area may include more then one MSC area and cells of more than one PLMN. Group call member: Any service subscriber or dispatcher participating in an on going voice group cal
39、l. 3.2 Abbreviations Abbreviations used in the present document are listed in TS 01.04. 4 Description The VGCS is defined in the following. Figure 1 gives an explanation of the logical concept of the VGCS. ETSI ETSI TS 100 925 V8.2.1 (2005-07) 7 3GPP TS 02.68 version 8.2.1 Release 1999 a) The VGCS e
40、nables a calling service subscriber or calling dispatcher to establish a voice group call to destination subscribers belonging to a predefined group call area and group ID. Applications for voice group call services typically involve multiple group members in a small group call area, for which the V
41、GCS should provide spectrum efficient solutions. b) The calling service subscriber as well as the destination service subscribers may be any service subscriber which has subscribed to the related group ID. The calling dispatcher may be any dispatcher who is entitled to originate VGCS calls to the re
42、lated call reference. c) Destination subscribers are all destination service subscribers or a group of destination service subscribers identified by the called group ID which have their present location in the group call area, and pre-registered destination dispatchers. Destination service subscribe
43、rs shall be notified with the group ID, not by paging the subscriber individually. Destination dispatchers shall be called individually with their identity. Service subscribers may become late destination subscribers when entering the group call area within 500 ms after reception of the first notifi
44、cation message related to the VGCS call. Service subscribers which leave the corresponding group call area during an on going VGCS call of which they are member cease to be destination subscribers. d) The voice group call shall be established in a group call area which is comprised of one or a clust
45、er 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 VGCS, the group call area is uniquely identified by the actual cell in which the service subscriber resides at the mome
46、nt of VGCS call initialization and by the group ID they issue. A calling dispatcher initiating a VGCS 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 group call management by verification of
47、 the calling identity. Since a dispatcher may be registered to more than one group call area and group ID an indication of the wanted group call area and group ID has to be given in form of a dedicated address called by the dispatcher. e) The service shall permit only one talking service subscriber
48、at any moment; additionally up to five dispatcher can be talking simultaneously at one time. Dispatchers should hear all combinations of voices other than their own. Listening service subscribers shall hear the combination of all voices. The talking service subscriber shall be given some indication
49、if any dispatchers are also talking. NOTE 1: The indication may be just the dispatchers voice. A dispatcher shall be able to talk at any moment , but the network operator may require him to signal the wish to talk to the network. If the network operator requires a dispatcher to indicate his wish to talk then a dispatcher in that network shall also indicate that he has finished speaking. Service subscribers who wish to talk shall indicate this. They shall only be able to become talking subscribers if there is no other talking service subscriber. The right to be a
