Integrated Services Digital Network (ISDN); Digital Subscriber Signalling System No. One (DSS1) ans Signalling System No.7 (SS7) Protocols; Call Fowarding on Not Reachable (CFNRc) Supplementary Service for Cordless Terminal Mobility (CTM) Phase 1; Part 1: Protocol Specification

This first part of EN 302094 specifies the stage 3 of the Signalling application for the mobility management service for the phase 1 of Call Forwarding on Not Reachable (CFNRc) supplementary service. The mobility management service functions include Cordless Terminal Mobility (CTM) for CTM phase 1 (DECT/GAP limitation) and DECT access to GSM via an ISDN user-network interface at the T reference point or coincident S and T reference point (as defined in ITU-T Recommendation 1.411 [3]) by means of the Digital Subscriber Signalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures and switching functions needed to support a telecommunication service (see CCITT Recommendation 1.130 [1]).

The Call Forwarding on Not Reachable (CFNRc) supplementary service enables a served user to have the network redirect to another user calls which are addressed to the served user's ISDN number. After the Call Forwarding on Not Reachable (CFNRc) supplementary service has been activated, calls are forwarded only if the served user's cordless terminal is not reachable. The Call Forwarding on Not Reachable (CFNRc) supplementary service operates on all calls. The served user's ability to originate calls is in principle unaffected by the Call Forwarding on Not Reachable (CFNRc) supplementary service.

NOTE: Practically the served user's ability to originate calls is affected if there is radio congestion or if the served user's cordless terminal is for example out of radio coverage

The signalling application for phase 1 describes the mobility management procedures required to allow users of cordless terminals to be mobile within and between networks. Whenever radio coverage is provided and the cordless terminal has appropriate access rights, the user is able to make calls from and to receive calls at any location within the network.

The signalling application for phase 1 is applicable to the telephony 3,1 kHz teleservice [7], speech bearer service [5] and 3,1 kHz audio bearer service [6].

Further parts of EN 302 094 specify the method of testing required to identify conformance to the present document.

The present document is applicable to equipment supporting the signalling application for the alpha interface or the beta interface, to be attached at either side of a T reference point and coincident S and T reference point when used as an access to the public ISDN or GSM.
