36、5.0.0 (2018-07)93GPP TS 23.278 version 15.0.0 Release 15functionality that was present in the HLR in previous 3GPP releases for storing the information relevant to the current subscription regarding CAMEL Subscription Information for IMS. The HSS sends IM CAMEL Subscription Information data to the I
37、M-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 state models. The IM-SSF also provides the CAMEL interface to HSS for downloading the subscribers CAMEL Subscriptio
38、n 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 users. As such, it identifies a set of basic call activities in a CSCF and shows how these activities are join
39、ed 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: IP Multimedia session and IP Multimedia call are treated as equivalent in this specification. Originating IP Mul
40、timedia 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 Multimedia CAMEL Subscription Information (O-IM-CSI): O-IM-CSI identifies the subscriber as having originating I
41、P 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 associated with the terminating party. Terminating IP Multimedia CAMEL Subscription Information (T-IM-CSI): T-IM-CSI id
