ETSI ETSI TS 124 615 V14.0.0 (2017-04)63GPP TS 24.615 version 14.0.0 Release 141 Scope The present document specifies the
29、 stage 3, Protocol Description of the Communication Waiting (CW) 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 Sessio
30、n Description Protocol (SDP). The Communication Waiting (CW) service 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 d
31、ocument is applicable to User Equipment (UE) and Application Servers (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
32、specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.

46、ction The Communication Waiting (CW) service enables a UE to be informed that no resources are available for an incoming communication. The user then has the choice of accepting, rejecting or ignoring the incoming communication (as per basic communication procedures). 4.2 Description 4.2.1 General d
47、escription Two cases can occur depending on the networks ability to validate the status of the destination user upon receipt of an incoming communication and where the CW condition is determined (i.e. “approaching NDUB“ condition): - network based CW, i.e. sufficient information on the user is avail
48、able at the time a communication is to be delivered to the user, the network validates the status of this user. 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 communic
49、ation waiting situation upon receipt from the destination user of a communication waiting indication (i.e. the CW condition is determined by the UE using UDUB). When a communication arrives at the destination user, the UE validates the status of the user. If the user is already involved in one or more communications, the terminal notifies the served user of a communication waiting situation. The user then has different possibilities to react, for example if it may decide to free some resources and accept the incoming communication. NOT
