The present document specifies the CAMEL Application Part (CAP) supporting the fourth phase of the network feature Customized Applications for Mobile network Enhanced Logic for IP Multimedia CN subsystems. CAP is based on a sub-set of the ETSI Core INAP CS-2 as specified by
EN 301 140-1 [4]. Descriptions and definitions provided by
EN 301 140-1 [4] are directly referenced by this standard in case no additions or clarifications are needed for the use in the CAP.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
-
References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
-
For a specific reference, subsequent revisions do not apply.
-
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

Terminating CAMEL BCSM for IMS
The CAP stage 3 specification for IMS re-uses the ASN.1 definitions of CAP version 3 as specified in 3GPP Rel-99
TS 29.078 with modifications for CAMEL/IMS interworking. A new Application Context has been created for IMS for Release 5.
For general specifications including lower layer services (i.e. TC and SCCP procedures) , refer to specifications found in
TS 29.078.
For IMS, the MRFC plays the role of a gsmSRF. The CAP operations sent between the gsmSCF and the MRFC are sent via the IM-SSF. The IM-SSF shall map the CAP operations intended for the MRFC into a SIP based protocol and sent to the MRFC via the S-CSCF. Standardization of the MRFC interface via S-CSCF is outside the scope of this specification.
