`Foreword
`
`This Global System for Mobile communications Technical Specification (GTS) has been produced by the
`Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards
`Institute (ETSI).
`
`This specification defines the stage 2 description of Customized Applications for Mobile network
`Enhanced Logic (CAMEL) within the digital cellular telecommunications system (Phase 2/Phase 2+).
`
`The contents of this TS are subject to continuing work within TC-SMG and may change following formal
`TC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI
`with an identifying change of release date and an increase in version number as follows:
`
`Version 5.x.y
`
`where:
`
`the third digit is incremented when editorial only changes have been incorporated in the
`specification;
`
`the second digit is incremented for all other types of changes, i.e. technical enhancements,
`corrections, updates, etc.

`
`Scope
`
`This Technical Specification (TS) specifies the stage 2 description for the first phase (see GSM 02.78 [2])
`of the Customized Applications for Mobile network Enhanced Logic (CAMEL) feature which provides the
`mechanisms to support services of operators which are not covered by standardized GSM services even
`when roaming outside the HPLMN.
`
`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.
`
`In this specification, the GSM Service Control Function (gsmSCF) is treated as being part of the HPLMN.
`The regulatory environment in some countries may require the possibility that the gsmSCF and the
`HPLMN are controlled by different operators, and the gsmSCF and the HPLMN are therefore distinct
`entities.
`
`In the first phase the CAMEL feature supports:
`mobile originated and forwarded calls;
`-
`mobile terminating calls;
`-
`any time interrogation;
`-
`suppression of announcements;
`-
`
`Note that CAMEL is not applicable to Emergency Setup (TS 12), i.e., in case an Emergency call has been
`requested the gsmSSF shall not be invoked.
`
`The mechanism described in this standard addresses especially the need for information exchange
`between the VPLMN or IPLMN and the HPLMN for support of operator specific services. Any user
`procedures for the control of operator specific services are outside the scope of this standard.
`Subscribers who have subscribed to operator specific services and therefor need the functional support of
`the CAMEL feature shall be marked in the HPLMN and VPLMN. In case a subscriber is marked to need
`CAMEL support, the appropriate procedures which provide the necessary information to the VPLMN or to
`the HPLMN are invoked. It is possible for the HPLMN to instruct the VPLMN or IPLMN to interact with a
`gsmSCF which is controlled by the HPLMN.
`
`The specification of operator specific services in HPLMN are outside the scope of this standard.

`3 Definitions and abbreviations
`
`3.1
`
`Definitions
`
`For the purposes of this GTS, the following definitions apply:
`
`Basic Call State Model (BCSM): The BCSM provides ahigh-level model of GMSC- or MSC/VLR-
`activities required to establish and maintain communication paths for users. As such, it identifies a set of
`basic call activities in a GMSC or MSC/VLR and shows how these activities are joined together to
`process a basic call.
`
`Detection Points (DP): The points in processing at which notifications (to the service logic) can occur
`and transfer of control (to the gsmSCF) is possible are called Detection Points (DPs).
`
`GSM Service Control Function (gsmSCF): A functional entity that contains the CAMEL service logic to
`implement OSS. It
