34、TS 02.69. Voice broadcast channel: Downlink to be allocated in each cell of the group call area for a particular voice broadcast call. All mobile stations of the destination subscriber being service subscribers in one cell shall listen to the common downlink. Group members: Service subscribers entit
35、led to belong to a particular group classified by a certain group identification (group ID). Voice broadcast call member: Any group member or dispatcher participating in an on going voice broadcast call. Broadcast call attributes: Group call area, dispatcher identities. Group Call Register (GCR): A
36、functionality in the network containing the broadcast call attributes. Group call anchor MSC: The MSC responsible for managing and maintaining a particular voice broadcast call. The group call anchor MSC is determined as the one controlling the cells of the group call area (see also group call relay
37、 MSC). For voice broadcast services where the group call area exceeds an 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 broadcast services wher
38、e the group call area exceeds one MSC area. Notification: Notifications are given on common 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 broadcast call on the existence of voice broadcast
39、calls. 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.

41、ce 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 receive voice broadcast calls associated with that group ID. In addition, certain group members are entitle
42、d by their subscription to initiate voice broadcast calls. Certain dispatchers connected to external networks also require the capability to initiate or receive voice broadcast calls. In addition to subscriber details in the HLR, it is necessary for the mobile station to be aware of its group member
43、ship by storing details on the SIM. This is required because it shall respond to notification messages 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 se
44、veral group IDs on the SIM. In active state the subscriber can initiate voice broadcast calls to that group ID. When in deactive state the subscriber can not make voice broadcast calls to the group and the mobile station ignores any notification for that group ID. 4.2 Broadcast process 4.2.1 Broadca
45、st call initiation 4.2.1.1 Normal operation with successful outcome A group call area can be restricted to a single MSC area or can exceed one MSC area (implementation option). A voice broadcast call shall be initiated by a calling service subscriber by a related input function, e.g. via MMI, specif
46、ying the selected serviceand the group ID dialled or by a calling dispatcher by the MSISDN address (see subclause 9.2). The MSC in which the voice broadcast call is initiated obtains (by requesting the Group Call Register (GCR, see clause 5) the group call attributes. This GCR interrogation after ca
47、ll initiation also determines whether the MSC shall act as anchor- or as relay MSC. If the MSC is not the anchor-MSC then the call will be “forwarded“ from the relay to the respective anchor-MSC (information also delivered by GCR) and further “call-establishment“ is done by the anchor-MSC as describ
48、ed in the following. When a calling service subscriber or calling dispatcher initiates a voice broadcast call, one voice broadcast channel shall 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 broadcast
49、 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. The calling service subscriber shall have a dedicated standard uplink/downlink. All mobile stations of the listening service subscribers in one cell shall only listen to the same common downlink (voice broadcast channel). Only one voice broadcast channel shall be established in each cell for any given
