Similarly, MSC B, VLR B and HLR B are the network elements pertaining to Destination B when Destination B is a GSM mobile. Origin

SSAP is the protocol used for CCBS procedures on the interface between the originating and destination network. Communicati

41、on across this interface is performed using SCCP Connectionless Signalling (Refer to ETS 300 358). Subscriber A: The user of MS A, requesting CCBS. Similarly, MSC A, VLR A and HLR A are the network elements pertaining to Subscriber A. ETSI ETSI TS 123 093 V14.0.0 (2017-04)73GPP TS 23.093 version 14.

42、0.0 Release 14Subscriber B: The user of destination B, who may not necessarily subscribe to CCBS. Subscriber C: The user of MS C, who is the forwarded-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

43、 that manages CCBS requests for a subscriber, when that subscriber is the target of CCBS Requests.

44、isted 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 when destination B becomes idle and to have the network automatically generate a CCBS call to destination B, if subscriber A desires. Subscriber A may mak

45、e distinct CCBS requests for calls to the same destination B for different basic services. 4.2 Architecture Figure 4.2.1 is an architectural overview of the CCBS service when interworking between the originating and the destination networks involved. The originating network may be a mobile network o

46、r 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 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 pro

47、tocol, which is signalled on the following interfaces: HLR A - HLR B; HLR A - DLE; OLE - HLR B.

48、the originating subscriber A or the destination subscriber B or both may be located outside of their HPLMNs during the CCBS service. 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

49、 refer to clause 10 where the exceptions are described in more detail. The signalling between different networks described in the subclause 4.2 applies also during roaming. HLR A and HLR B belongs always to the HPLMN of the subscriber whereas VLR A and MSC A and GMSC, VLR B and MSC B respectively may belong to a HPLMN or VPLMN. Refer to TS 23.018 where call handling in the mobile network is described in more detail.
