1 Scope
This standard specifies the stage 1 description for the CAMEL feature (Customised Applications for Mobile network
Enhanced Logic) which provides the mechanisms to support services consistently independently of the serving network.
The CAMEL features shall facilitate service control of operator specific services external from the serving PLMN. The
CAMEL feature is a network feature and not a supplementary service. It is a tool to help the network operator to
provide the subscribers with the operator specific services even when roaming outside the HPLMN.
If an IPLMN or VPLMN supports CAMEL Phase 4, it shall also provide the functionality of all previous CAMEL
phases.
Phase 4 network signalling shall support interworking with CAMEL Phases 3 and 2.
The CAMEL feature is applicable
- To mobile originated and mobile terminated call related activities;
- To supplementary service invocations;
- To SMS MO, to GPRS sessions and PDP contexts, to the control of HLR subscriber data, to the control of
network signalling load.
The mechanism described addresses especially the need for information exchange among the VPLMN, HPLMN and the
CAMEL Service Environment (CSE) for support of such operator specific services. Any user procedures for operator
specific services are outside the scope of this standard.
This specification describes the interactions between the functions of the VPLMN, HPLMN, IPLMN and the CSE.
The second phase of CAMEL enhances the capabilities of phase 1 where the following capabilities have been added:
- Additional event detection points;
- Interaction between a user and a service using announcements, voice prompting and information collection via in
band interaction or USSD interaction;
- Control of call duration and transfer of Advice of Charge Information to the mobile station;
- The CSE can be informed about the invocation of the supplementary services ECT, CD and MPTY;
- For easier post-processing, c
