6、 Q.1741.9 identifies a release of the IMT-2000 family member, “GSM evolved UMTS Core Network“. This release of the family member is known to the standards development organizations (i.e., ARIB, CCSA, ETSI, ATIS, TTA, TTC) as the “3GPP Release 11“. Earlier releases, known as “3GPP Release 99“, “3GPP
7、Release 4“, “3GPP Release 5“, “3GPP Release 6“, “3GPP Release 7“, “3GPP Release 8“, “3GPP Release 9“ and “3GPP Release 10“, of this family member are specified in Recommendations ITU-T Q.1741.1, Q.1741.2, Q.1741.3, Q.1741.4, Q.1741.5, Q.1741.6, Q.1741.7 and Q.1741.8, respectively, while other IMT-20
8、00 family members are specified in other ITU T Recommendations in the ITU-T Q.174x series. This Recommendation combines and associates the relevant standards from a number of standards development organizations for the core network for this IMT-2000 family member into a global Recommendation.

ITU-T Q.1741.9 (06/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies
11、(ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T 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 Telecommunicat
12、ion Standardization Assembly (WTSA), which meets every four years, establishes the topics for study 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 in
13、formation technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative 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 a
14、gency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain 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 s
15、ome other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or
16、 implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. 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 p
17、rocess. As of the date of approval of this Recommendation, ITU had not received notice of intellectual 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 stro
