20、duced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) and originally published as parts of ETSI TS 181 005 11. It was transferred to the 3rdGeneration Partnership Project (3GPP) in July 2008. The contents of the present do
21、cument are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present 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 wher
22、e: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under 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 i
23、ncremented when editorial only changes have been incorporated in the document. Introduction The present document specifies the requirements that need to be fulfilled by NGN technical specifications to provide services in an NGN. The present document considers one service set: IP Multimedia Services.
24、 Other service sets and generic network requirements to support service deployment and interoperability, are contained in ETSI TS 181 005 11. The present document provides generic requirements on networks from a services point of view. Specific details of individual services and capabilities are pro
25、vided in other documents. ETSI ETSI TS 122 495 V7.0.0 (2008-11) 6 3GPP TS 22.495 version 7.0.0 Release 7 1 Scope The present document specifies network requirements in terms of service-related capabilities for a TISPAN NGN incorporating an IMS. The present document places requirements for TISPAN NGN
26、 Release 1 subsystems. The present document provides generic requirements for services and interoperability in a TISPAN NGN incorporating an IMS in terms of the capabilities for a network or networks. Requirements on service-related subsystems provide sufficient detail for architecture, networking r
27、equirements and protocols to be specified. Specific service requirements may be contained in other documents, as identified in the present document, and by other documents referencing the present document. The present document does not define services, only capabilities and requirements. The present
28、 document does not place requirements on terminals or other customer-owned equipment. The present document specifies the service-related requirements on an IMS that are used to determine the network architecture, requirements and control protocols for a network interface to a customer environment. N
29、OTE: The present document uses the term “NGN“ only in the context of ETSI TISPAN. 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 n
30、umber, 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 implicitly refers to the latest vers
