34、nitions used in the present document are also defined in 3GPP TS 02.68. For the purposes of the present document, the following terms and definitions apply. voice group call channel: Combined uplink/downlink to be allocated in a cell of the group call area for a particular voice group call. The upli

35、nk can be used by the presently talking service subscriber only. All mobile stations of the listening service subscribers in one cell shall listen to the common downlink. group members: Service subscribers entitled to belong to a particular group classified by a certain group identification (group I

36、D). voice group call member: Any group member or dispatcher participating in an on going voice group call. group call attributes: Group call area, dispatcher identities, and the non-activity time which results in the release of the voice group call by the network. Group Call Register (GCR): A functi

37、onality in the network containing the group call attributes. group call anchor MSC: The MSC responsible for managing and maintaining a particular voice group call. The group call anchor MSC is determined as the one controlling the cells of the group call area (see also group call relay MSC). For voi

38、ce group call services where the group call area exceeds one MSC area, the group call anchor MSC is predefined in the network. group call relay MSC: MSC controlling cells of a group call area which are not under control of the group call anchor MSC for those voice group call services where the group

39、 call area exceeds one MSC area. notification: Notifications are given on common control channels or dedicated channels in order to inform group members which are either in idle mode or in dedicated mode or participating in a voice group call or voice broadcast call on the existence of voice group c

40、alls. Notification Channel (NCH): Common control channel on which the notifications are sent by the network (equivalent to a paging channel). 3.2 Abbreviations Abbreviations used in the present document are also listed in 3GPP TS 21.905. For the purposes of the present document, the following abbrev

41、iations apply: eMLPP enhanced Multi-Level Precedence and Pre-emption GCR Group Call Register NCH Notification Channel VBS Voice Broadcast Service VGCS Voice Group Call Service ETSI ETSI TS 100 933 V8.6.0 (2005-06) 8 3GPP TS 03.68 version 8.6.0 Release 1999 4 Main concepts 4.1 Group definition Servic

42、e subscribers can become group members on a PLMN wide basis to one or more groups pre-defined in the network by a corresponding group identification (group ID). The membership enables them to initiate or receive voice group calls associated with that group ID. Certain dispatchers connected to extern

43、al networks also require the capability to initiate or receive voice group calls. In addition to subscriber details in the HLR, it is necessary for the mobile station to be aware of its group membership by storing details on the SIM. This is required because it shall respond to notification messages

44、 which include only the group ID (i.e. no IMSI or TMSI details). Having become a group member, each service subscriber can set to active state or deactive state the group ID or any one out of his several group IDs on the SIM. In active state the subscriber can initiate voice group calls to that grou

45、p. When in deactive state the subscriber can not make voice group calls to the group and the mobile station ignores any notification for that group. 4.2 Group conversations 4.2.1 Group call initiation 4.2.1.1 Normal operation with successful outcome A group call area can be restricted to a single MS

46、C area or can exceed one MSC area (implementation option). A voice group call shall be initiated by a calling service subscriber by a related input function, e.g. via MMI, specifying the selected service and the group ID dialled or by a calling dispatcher by the MSISDN address (see subclause 9.2). T

47、he MSC in which a voice group call is initiated obtains (by requesting the Group Call Register (GCR, see clause 5) the group call attributes. This GCR interrogation after call initiation also determines whether the MSC shall act as anchor or as relay MSC. If the MSC is not the MSC then the call will

48、 be “forwarded“ from the relay to the respective MSC (information also delivered by GCR) and further “call-establishment“ is done by the anchor MSC as described in the following. When a calling service subscriber or calling dispatcher initiates a voice group call, one voice group call channel shall

49、be established in each cell of the group call area and notifications for that call shall be sent in each of these cells. As an alternative, voice group call channels may only be established in cells in reaction to responses received from mobile stations on the notifications. At the same time standard connections to dispatchers in the mobile network or in an external network shall be established. A voice group call channel shall consist of a combined uplink/downlink. The uplink will be used exclusively by the presently talking service subscriber
