Broadca
37、st call channel: downlink channel to be allocated in each cell of the group call area for a particular broadcast call. All MSs of the listening service subscribers in one cell shall listen to the common downlink. Broadcast call: is used in the same sense as “voice broadcast call“. Calling user: BCC
38、entity in the Mobile Station (MS) initiating or having initiated a broadcast call. ETSI ETSI TS 144 069 V14.0.0 (2017-04)73GPP TS 44.069 version 14.0.0 Release 14Clearing the context related to the broadcast call establishment: all running BCC timers in the relevant BCC entity are stopped, all attri
39、butes in the relevant BCC entity are deleted. Downlink: network to MS direction. Group receive mode: See 3GPP TS 44.018. Originating mobile station: MS initiating or having initiated the broadcast call. Uplink: Mobile station to network direction. 3.2 Abbreviations For the purposes of the present do
40、cument, the abbreviation defined in 3GPP TR 21.905 1a and the following applies: BCC Broadcast Call Control 4 Applicability Support of the broadcast call protocol is optional in the MS and in the network. 5 Main concepts The present document describes the broadcast call control (BCC) protocol, which
41、 is one of the protocols of the Connection Management (CM) sublayer (see 3GPP TS 24.007). There is in general more than one MS engaged in a broadcast call. Consequently, there is in general more than one MS with a BCC entity engaged in the same broadcast call, and there is one BCC entity in the netw
42、ork engaged in that broadcast call. Under which conditions a BCC message is passed from lower (sub-)layers to the BCC entity is defined in the specifications of the sub-layers. The MS shall ignore BCC messages that it receives which were sent in unacknowledged mode and which explicitly specify as de
43、stination a mobile identity which is not a mobile identity of the MS. Higher layers and the MM sub-layer decide when to accept parallel BCC transactions and when/whether to accept BCC transactions in parallel to other CM transactions. The broadcast call may be initiated by a mobile user or by a disp
44、atcher. Specification of a protocol for dispatchers is out of the scope of the present document. Hence, in the scope of the present document, there are: - one BCC entity in the network; and - one or more than one BCC entities in different MSs; engaged in a broadcast call, and one ore none of the MSs
45、 is the originator of the broadcast call (called the originating MS in the present document). NOTE: Whereas for the Group Call Control (GCC) protocol (see 3GPP TS 44.068), in certain situations, the GCC entity in a MS assumes to be the originator of a broadcast call without being the originator, thi
46、s is not the case for the BCC protocol. The originator of the BCC transaction chooses the Transaction Identifier (TI). A MS not assuming to be the originator of the transaction will chose the transaction identifier received from the network, setting the TI flag to 1+x mod 2 where x is the received T
47、I flag. ETSI ETSI TS 144 069 V14.0.0 (2017-04)83GPP TS 44.069 version 14.0.0 Release 14The present document describes the broadcast call control protocol only with regard to two peer entities, one in a MS, the other one in the network. The call control entities are described as communicating finite
48、state machines which exchange messages across the radio interface and communicate internally with other protocol (sub)layers. In particular, the BCC protocol uses the MM and RR sublayer specified in 3GPP TS 24.008 and 3GPP TS 44.018. The BCC entity in a MS that is not the originator of the broadcast
49、 call shall not send messages to its peer entity. This description in only normative as far as the consequential externally observable behaviour is concerned. For simplicity, instead of using the terms “BCC entity in the MS“ and “BCC entity in the network“, the present document often uses the terms “MS“ and “network“ if no confusion may arise. Certain sequences of actions of the two peer entities compose “elementary procedures“ which are used as a basis for the description in the present document. These elementary procedures are defined in clause
