ITU-T RECOMMENDATION 4.1721 INFORMATION FLOWS FOR IMT-2000 CAPABILITY SET 1 Summary This Recommendation specifies Stage 2 information flow procedures for the support of end-to-end inter-family and inter-system IMT-2000 Capability Set 1 (CS- 1) services and
6、network capabilities. The areas covered are mobility management, call and bearer control, services control, and over-the-air authorization services. Source ITU-T Recommendation 4.1721 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution 1 procedure on 15 June 2
7、000. Keywords CN, CS-1, IMT-2000, LMFh, LMFv, MT, “I, RAN, UIM, VHE. Recommendation 4.1721 (06/2000) 1 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a perma
8、nent organ of the ITU. The 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 Conference (WTSC), which meets every four years
9、, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall withi
10、n ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS T
11、he ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by
12、 ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned tha
13、t this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2000 All rights reserved.

27、0 Capability Set 1 (CS-1) services and network capabilities. It is specified according to the Stage 2 methodology described in ITU-T Recommendation 4.65 i. Companion ITU-T Recommendations, Q. 1701 2 and Q. 171 1 3, form the basis for this Recommendation. Used together, these Recommendations form a S
28、tage 2 description that identifies the functional capability and information flows needed to support the Stage 1 IMT-2000 services and network capabilities. This Recommendation covers information flows for the UIM to MT interface, the MT to RAN+CN interface, and the CN to CN interface (also known as
29、 the “1.) The information flows described cover the successful cases only. The unsuccessful cases are outside the scope of this Recommendation and are best handled as part of the Stage 3 development. Companion Q-series Recommendations Q. 173 1, Q. 174 1 and Q. 175 1 complement the end-to-end view of
30、 Recommendation Q. 172 1 by addressing interface specific aspects of these interfaces. This Recommendation does not include Radio Resource Management (RRM), Base Station Management (BSM) or RAN-CN information flows. RRM is covered elsewhere. BSM and RAN-CN information flows are outside the scope of
31、IMT-2000 CS-1 per section 8.l/Q. 1701. The following paragraphs provide a brief overview of the contents of each of the clauses of this Recommendation. Clauses 2, 3 and 4 provide references, definitions and a list of abbreviations and acronyms relevant to the content of this Recommendation. Clause 5
32、, “Introduction“, provides context for the remainder of this Recommendation. It includes the overall protocol architecture, identification of the functional models used from Recommendation Q. 17 1 1, an end-to-end network model, information flow sequence types and the information flow template. Clau
33、se 6, “Mobility Management“, describes the information flows for managing authentication, including UIM holder verification, user and network authentication and terminal identification. It then addresses location management, including geographic positioning, subscriber data management, user profile
34、interrogation, identity retrieval, registration management and location data fault recovery. Clause 7, “Call and Bearer Control“, describes basic incoming and outgoing mobile calls, including terminal paging, routing, emergency calls and priority calls. Clause 8, “Multimedia Call and Bearer Control“
35、, describes information flows and procedures for changing a teleservice during a call (switching between voice and data communications), adding and dropping a medium within an existing call, and changing communication configurations by adding and dropping a party in a data call. Access to the Intern
36、et is also covered in this clause. Clause 9, “Virtual Home Environment“, provides the information flows for the Direct Home Command (DHC) and Relay Service Control (RSC) methods. (The use of IN to support supplementary services within a network is outside the scope of this Recommendation.) Clause 1
37、O, “Messaging Service Applications“, describes short message services, teleservice message broadcast and message waiting notification information flows and procedures. Recommendation 4.1721 (06/2000) 1 Clause 1 1, “Generic Supplementary Service Procedures“, provides information flows for a suite of
38、general purpose procedures that may be used by various supplementary services. Clause 12, “Over-the-Air Service Provisioning“, describes information flows for over-the-air service provisioning procedures. Clause 13, “Definitions of Information Elements“, defines what the various information elements
39、 used in this Recommendation mean. Annex A provides a listing of all the common procedure modules used within this Recommendation and the clause number where they are described. Appendix I, “Q. 172 1 Coverage of Table l/Q. 170 1, Capability Set 1 Requirements“, provides linkage between Table UQ.1701
40、, the capabilities required of IMT-2000 Capability Set 1 and the contents of this Recommendation. Appendix II, “A-Key Generation“, provides a brief overview of this topic, including the Diffie-Hellman algorithm. Appendix III, “Bibliography“, provides a list of additional references to supplement the
41、 specific references listed in clause 2. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

48、d to the mobile terminal. The anchor core network may be either the home or the visited network. 3.2 man machine interface: The interaction of the user and network via a subscriber device. 3.3 request indication: The information flow sent rom one functional entity to another requesting a specific ac
49、tion. This is referred to as req.ind. 3.4 response confirmation: The information flow sent by the requested functional confirming that the requested action has been successfully completed. This is referred to as resp.conf. 3.5 service application: The provision of services by general purpose capabilities, such as Intelligent Network capabilities as applied at the home location or at a visited location as part of a Virtual Home Environment. 3.6 service control: Functions that set or modify the context, in which basic calls and bearers are established, modified and released. 3.7 subscr
