ETSI ETSI TS 124 615 V15.0.0 (2018-07)63GPP TS 24.615 version 15.0.0 Release 151 Scope The present document specifies the stage 3, Protocol Description of the Communication Waiting (C
31、W) service, based on stage 1 and stage 2 of the ISDN call waiting supplementary services. It provides the protocol details in the IP Multimedia (IM) Core Network (CN) subsystem based on the Session Initiation Protocol (SIP) and the Session Description Protocol (SDP). The Communication Waiting (CW) s
32、ervice enables a user to be informed, that very limited resources are available for an incoming communication. The user then has the choice of accepting, rejecting or ignoring the waiting call (as per basic call procedures). The present document is applicable to User Equipment (UE) and Application S
33、ervers (AS) which are intended to support the CW supplementary service. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, v

If the status of the user is “approaching NDUB“, the network presents the waiting communication to the destination user; or - terminal based CW, the network may be informed of the communicatio
