scope:

This final draft European Telecommunication Standard (ETS) describes the stage one of the location handling services for Private Integrated Services Telecommunication Networks (PISNs). It comprises two related but distinct service descriptions. The first is a service allowing a Cordless Terminal Mobility (CTM) user to register or deregister at a location area in the PISN (SS-CTLR). The second is an Additional Network Feature (ANF) used by different parts of the PISN to transfer or access service profiles (ANF-CTSP). Stage one is an overall service description from the user's point of view, but does not deal with the details of the human interface itself, see CCITT Recommendation I.130 [5].

The Cordless Terminal Location Registration Supplementary Service (SS-CTLR) enables a CTM user to register at, or deregister from, the current location area within the PISN. The ability to register at different location areas in the PISN 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 PISN that the CTM user is temporarily unable to make use of the provided services (including the receipt of incoming calls).

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

This ETS contains the stage 1 specification of the location handling services. Service specifications are produced in three stages according to the method described in ETS 300 387 [4].

The purpose of the stage 1 specification is to guide and constrain the work at stage 2 and stage 3. Where the text indicates the status of a requirement (i.e. as strict command or prohibition or as authorisation leaving freedom as a capability or possibility) this is reflected in the text of the relevant stage 2 and stage 3 standards.

This ETS applies to CTM only within a single PISN.

Conformance to this ETS is met by conforming to the stage three standards with the field of application appropriate to the equipment being implemented. Therefore, no method of testing is provided for this ETS.
