scope:

This European Telecommunication Standard (ETS) describes the stage two of the location handling services for Private Telecommunication Networks (PTNs) which provide Cordless Terminal Mobility (CTM) user mobility capability.

The Cordless Terminal Location Registration Supplementary Service (SS-CTLR) enables a CTM user to register at, or deregister from, the current location within the PTN. The ability to register at different locations in the PTN at different times enables the CTM user to maintain the provided services (including the ability to make and receive calls) at different access points. Deregistration is used to inform the PTN that the CTM user is temporarily unable to make use of the provided services (including the receipt of incoming calls).

The Transfer of Service Profile Additional Network Feature (ANF-CTSP) enables different parts of the PTN to transfer or access service profiles, thereby allowing CTM users to maintain their service profiles when changing location within the PTN.

Supplementary service specifications are produced in three stages according to the method specified in ENV 41005 [3]. Stage 2 identifies the functional entities involved in the feature and the information flows between them.

The purpose of the stage 2 specification is to guide and constrain the work on signalling protocols at stage 3, while fulfilling the requirements of stage 1. Stage 1 and stage 3 are defined in separate standards.

This ETS applies to CTM only within a single PTN. The specification of information flows between the PTN and cordless terminals is beyond the scope of this ETS.

Conformance to this ETS is met by conforming to a stage 3 standard which fulfils the requirements of this ETS that are relevant to the equipment for which the stage 3 standard applies. Therefore, no method of testing is provided for this ETS.
