The present document is part 1 of a multi-part deliverable covering the signalling application for the mobility

Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";

This first part of EN 301 144 specifies the stage 3 of the signalling application for the mobility management service on

the alpha interface. The mobility management service functions include Cordless Terminal Mobility (CTM) for CTM

phase 1 (DECT/GAP limitation) and DECT access to GSM via an Integrated Services Digital Network (ISDN)

user-network interface at the T reference point or coincident S and T reference point (as defined in

ITU-T Recommendation I.411 [18]) 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

The signalling application for the alpha interface 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

The signalling application for the alpha interface is applicable to the telephony 3,1 kHz teleservice (see

ETS 300 111 [3]), speech bearer service (see ETS 300 109 [1]) and 3,1 kHz audio bearer service (see ETS 300 110 [2]).

Further parts of EN 301 144 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, 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
