6、he 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 7“. Earlier releases, known as “3GPP Release 99“, “3GPP Release 4“, “3GPP Release 5“, and “3
7、GPP Release 6“, of this Family Member are specified in Recommendations ITU-T Q.1741.1, Q.1741.2, Q.1741.3, and Q.1741.4, respectively, while other IMT-2000 Family Members are specified in other ITU-T Recommendations in the Q.174x series. This Recommendation combines and associates the relevant stand
8、ards from a number of Standards Development Organizations for the core network for this IMT-2000 Family Member into a global Recommendation. Source Recommendation ITU-T Q.1741.5 was approved on 14 October 2008 by ITU-T Study Group 19 (2005-2008) under Recommendation ITU-T A.8 procedure. Keywords Cor

ITU-T Q.1741.5 (10/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Teleco
10、mmunication 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 Telecommunication Standardization As
11、sembly (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 information technology w
12、hich 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 agency. Compliance with
13、 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 some other obligatory la
14、nguage 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 RIGHTS ITU draws attention to the possibility that the practice or implementation of thi
15、s 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 process. As of the date
16、 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 strongly urged to consult

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 7“. The core network interfaces identified in this Recommendation and the radio int
38、erfaces and radio access interfaces which are identified in ITU-R M.1457-7 constitute a complete system specification for the 3rd generation mobile system for terrestrial usage of this IMT-2000 Family Member. It is the intent of the ITU-T that the references in this Recommendation are only to specif
39、ications that specify the network aspects of this IMT-2000 Family Member. In the event that a referenced specification also includes material that specifies any of the radio aspects of this IMT-2000 family member, ITU-R M.1457-7 shall take precedence. NOTE The structure and content of this Recommend
40、ation have been organized for ease of use by those familiar with the original source material; as such, the usual style of ITU-T Recommendations has not been applied. 2 References1The following ITU-T Recommendations and other references contain provisions which, through reference in this text, const
