27、7.0.0 Release 7 1 Scope The present document specifies the stage three (protocol description) of the Explicit Communication Transfer (ECT) simulation service, based on stage one and two of the ISDN ECT supplementary service. Within the Next Generation Network (NGN) the stage 3 description is specifi

28、ed using the IP Multimedia Call Control Protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either spec

29、ific (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. In the case of a reference to a 3GPP document (including a GSM document), a non-speci

47、ption 4.2.1 General description The Explicit Communication Transfer (ECT) service provides a party involved in a communication to transfer that communication to a third party. There are three actors active in a transfer, they are acting in the following roles: transferor, the party that initiates th

48、e transfer of the active communication that it has with the transferee; transferee, the party which stays in the communication which is transferred; and transfer target, the party which the communication is transferred to and which replaces the transferor in the communication. Assumption is that ini

49、tially the transferee and the transferor are involved in a communication. In the present document: the party that originated the original communication before transfer is tagged with UE-A; the party that terminated the original communication before transfer is tagged UE-B; and the party that is newly introduced into communication with the transferee, e.g. the transfer Target is tagged UE-C. There are two initial situations possible in which transfer shall be possible: The transferor has no ongoing consultation communication
