24、iginally published as ETSI TS 183 029 20. It was transferred to the 3rd Generation Partnership Project (3GPP) in December 2007. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the p
25、resent document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under
26、change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document.

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
30、fic reference implicitly refers to the latest version of that document in the same Release as the present document. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. For online referenced documents, informati
31、on sufficient to identify and locate the source shall be provided. Preferably, the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the reference should, as far as possible, remain valid for the expected life of the document. The reference shal
32、l include the method of access to the referenced document and the full network address, with the same punctuation and use of upper case and lower case letters. NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee their long term validity. 2.1

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
