Full Description

This standard specifies the stage 1 description for the first phase of 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. The CAMEL feature is applicable to mobile originated and mobile terminated call related activities. 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. The specification of operator specific services in HPLMN are outside the scope of this standard. This specification describes only the interactions between the VPLMN, HPLMN, IPLMN and the CSE.
