28、428 version 7.2.0 Release 7 1 Scope The present document describes the stage three protocol for basic communication procedures common to several services when at least one Application Server (AS) is included in the communication. The common procedures are based on stage three specifications for serv
29、ices. The present document contains examples of signalling flows for the common basic communication procedures. 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
30、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-specific reference implic
31、itly 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, information sufficient to ide
32、ntify 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 shall include the method
33、 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 Normative reference

49、port the progress of a communication request. The announcement may be of any type of media e.g. an audio announcement or a video clip. Clause 4.2 describes the announcement common procedure and annex A shows examples of signalling flows for some announcement scenarios. Some services are triggered by a users busy condition e.g. the Communication Forwarding on Busy service. The busy condition may be determined by the network i.e. the Network Determine User Busy (NDUB) condition or by the user i.e. the User Determine User Busy (UDUB) condi
