J.366.0 (11/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T
5、 is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study
6、 by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a co
7、llaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain ce
8、rtain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express require
9、ments. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right.
10、 ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectu
11、al property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

14、 industries IMS initiative to the needs of the cable industry. A delta Recommendation references another document and then shows only the changes necessary to adapt the other document to the current needs. It is an important objective of this work that interoperability between IPCablecom 2.0 and 3GP
15、P IMS is provided. IPCablecom 2.0 is based upon 3GPP IMS, but includes additional functionality necessary to meet the requirements of cable operators. Recognizing developing converged solutions for wireless, wireline, and cable, it is expected that further development of IPCablecom 2.0 will continue
16、 to monitor and contribute to IMS developments in 3GPP, with the aim of alignment of 3GPP IMS and IPCablecom 2.0. 2 References 2.1 Normative references None. 2.2 Informative references ITU-T Recommendation J.360 (2006), IPCablecom2 Architecture Framework Main document. 3GPP TS 23.002, Network archit

18、n Protocol TS Technical Specification 5 Introduction Interworking with other networks, particularly wireless networks, and reducing development cost are two of the main factors driving the choice of technologies for IPCablecom2. With these objectives in mind, it was agreed to base IPCablecom2 on Rel
19、ease 6 (the latest available at the time work started) of the IP Multimedia Subsystem (IMS) as defined by the 3rd Generation Partnership Project (3GPP). 3GPP is a collaboration agreement between various standards bodies. The scope of 2 ITU-T Rec. J.366.0 (11/2006) 3GPP is to produce Technical Specif
20、ications and Technical Reports for GSM and 3rd Generation (3G) Mobile System networks. The scope of 3GPP includes development of a SIP-based IP-communications architecture for mobile networks. The resulting architecture, dubbed the IP Multimedia Subsystem, defines how various protocols (e.g., SIP an
21、d DIAMETER) can be used in a system-level architecture to provide SIP-based communication services. While many of the functional entities and reference points defined in the IMS have broad applicability in other industries, Release 6 of the IMS is a wireless-centric architecture, designed to meet th
22、e business and operational needs of the wireless industry. Therefore, it does not meet all of the needs of the cable industry. IPCablecom2 enhances the IMS to support the unique technology requirements of the cable industry, and also addresses cable operator business and operating requirements. 3GPP
23、 is developing newer releases of the IMS specifications. Future updates to IPCablecom2 will align with these newer releases as necessary. Refer to 3GPP TS 23.002 (Network architecture) for additional information on the 3GPP IMS architecture and to ITU-T Rec. J.360 for additional information on IPCab
24、lecom2. Since the changes to the 3GPP specifications are relatively minor, the 3GPP specifications have been referenced with only the changes needed by the cable industry shown: hence the use of delta Recommendations. 6 Recommendations IMS Delta Recommendations Document Name J.366.0 IPCablecom2 IP M
