41、called by subscriber A. Similarly, MSC B, VLR B and HLR B are the network elements pertaining to Destination B when Destination B is a GSM mobile. Originating queue: The queue that manages CCBS requests for a subscriber, when that subscriber is the originator of those CCBS Requests. SSAP: Supplement

42、ary Service Application Part. SSAP is the protocol used for CCBS procedures on the interface between the originating and destination network. Communication across this interface is performed using SCCP Connectionless Signalling (Refer to ETS 300 358). Subscriber A: The user of MS A, requesting CCBS.

43、 Similarly, MSC A, VLR A and HLR A are the network elements pertaining to Subscriber A. Subscriber B: The user of destination B, who may not necessarily subscribe to CCBS. ETSI ETSI TS 123 093 V15.0.0 (2018-07)73GPP TS 23.093 version 15.0.0 Release 15Subscriber C: The user of MS C, who is the forwar

44、ded-to-party when call forwarding applies. Similarly, MSC C, VLR C and HLR C are the network elements pertaining to Subscriber C. Target queue: The queue that manages CCBS requests for a subscriber, when that subscriber is the target of CCBS Requests. Timers: For each of the service timers, the loca

45、tion, start and stop conditions and action on expiry are given - Refer to subclause 5.1. 3.2 Abbreviations Abbreviations used in this specification are listed in 3GPP TR 21.905. 4 General 4.1 Overview The CCBS service allows a calling subscriber A, encountering a NDUB destination B, to be notified w

46、hen destination B becomes idle and to have the network automatically generate a CCBS call to destination B, if subscriber A desires. Subscriber A may make distinct CCBS requests for calls to the same destination B for different basic services. 4.2 Architecture Figure 4.2.1 is an architectural overvi

47、ew of the CCBS service when interworking between the originating and the destination networks involved. The originating network may be a mobile network or a fixed network and the destination network may also be a mobile network or a fixed network. The call related signalling for CCBS is performed on

48、 ISUP links on the following interfaces: VMSC A - GMSC B; VMSC A - DLE; OLE - GMSC B; whereas the specific CCBS procedures are performed via the SSAP protocol, which is signalled on the following interfaces: HLR A - HLR B; HLR A - DLE; OLE - HLR B.

When all the involved networks support CCBS service the normal handling described in this specification applies. When some network entities do not support CCBS service refer to clause 10 where the exceptions are described in more detail. The signalling between different networ
