34、 the subscription related information to support the network entities actually handling calls/sessions. For subscribers requiring CAMEL support, the HSS includes some functionality that was present in the HLR in previous 3GPP releases for storing the information relevant to the current subscription
35、regarding CAMEL Subscription Information for IMS. The HSS sends IM CAMEL Subscription Information data to the IM-SSF and CSE using a MAP interface. IP Multimedia Service Switching Function (IM-SSF): CAMEL functional entity that provides the interworking between SIP session control and the CAMEL stat
36、e models. The IM-SSF also provides the CAMEL interface to HSS for downloading the subscribers CAMEL Subscription Information data for IMS. IP Multimedia Basic Call State Model (IM-BCSM): IM-BCSM provides a high-level model of CSCF activities required to establish and maintain communication paths for
37、 users. As such, it identifies a set of basic call activities in a CSCF and shows how these activities are joined together to process a basic call. IP Multimedia CAMEL Subscription Information (IM-CSI): IM-CSI identifies the subscriber as having IP Multimedia CAMEL services. IP Multimedia session: I
38、P Multimedia session and IP Multimedia call are treated as equivalent in this specification. Originating IP Multimedia Basic Call State Model (O-IM-BCSM): originating half of the IM-BCSM. The O-IM-BCSM corresponds to that portion of the IM-BCSM associated with the originating party. Originating IP M
39、ultimedia CAMEL Subscription Information (O-IM-CSI): O-IM-CSI identifies the subscriber as having originating IP Multimedia CAMEL services. Terminating IP Multimedia Basic Call State Model (T-IM-BCSM): terminating half of the IM-BCSM. The T-IM-BCSM corresponds to that portion of the IM-BCSM associat
40、ed with the terminating party. Terminating IP Multimedia CAMEL Subscription Information (T-IM-CSI): T-IM-CSI identifies the subscriber as having terminating IP Multimedia CAMEL services. 3.2 Abbreviations Abbreviations used in the present document are listed in 3GPP TR 21.905 1.

48、for IP Multimedia session requiring CAMEL support. General registration procedure is detailed in 3GPP TS 23.228 6. Upon notification of a UEs registration, the IM-SSF requests O-IM-CSI, D-IM-CSI, VT-IM-CSI data from the HSS over the Si interface. Figure 4.1: Functional architecture for support of CA
