8、 beyond IMT-2000. ii ITU-T Rec. Q.1762/Y.2802 (09/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is

9、 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 Assembly (WTSA), which meets every four years,

10、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 which fall within ITU-Ts purview, the necessar

11、y 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 this Recommendation is voluntary. However, t

12、he 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 language such as “must“ and the negative equival

13、ents 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 this Recommendation may involve the use of a clai

14、med 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 of approval of this Recommendation, ITU had n

15、ot 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 the TSB patent database at http:/www.itu.int/I

Q.1762/Y.2802 (09/2007) 1 ITU-T Recommendation Q.1762/Y.2802 Fixed-mobile convergence general requirements 1 Scope and purpose This Recommendation is inten

22、ded to be used as the general requirements document leading to the development of recommendations and implementation guidelines for the realization of fixed-mobile convergence (FMC). This is to ensure that all elements required for interoperability and the associated network capabilities to support

23、applications globally across an FMC environment are adequately addressed by ITU-T standardization activities. The scope of this Recommendation is to provide FMC principles, high-level service requirements and capabilities. More specifically, this Recommendation identifies the fundamental characteris

24、tics, requirements and capabilities that FMC supports. As next generation networks (as described in ITU-T Y.2011) evolve, they will increasingly support the general FMC requirements and capabilities defined in this Recommendation. NGN specific FMC requirements will be captured in releasing specific

25、NGN requirements Recommendations. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

34、where: 3.1.1 identifier ITU-T Y.2091: An identifier is a series of digits, characters and symbols or any other form of data used to identify subscriber(s), user(s), network element(s), function(s), network entity(ies) providing services/applications, or other entities (e.g., physical or logical obje

35、cts). Identifiers can be used for registration or authorization. They can be either public to all networks, shared between a limited number of networks or private to a specific network (private IDs are normally not disclosed to third parties). 3.2 Terms defined in this Recommendation This Recommenda

36、tion defines the following terms: 3.2.1 fixed mobile convergence: In a given network configuration, the capabilities that provide services and application to the end user defined in ITU-T Y.2091 regardless of the fixed or mobile access technologies being used and independent of the users location. I

37、n the NGN environment ITU-T Y.2011, it means to provide NGN services to end users regardless of the fixed or mobile access technologies being used. 3.2.2 fixed network: A network that provides wire-based (e.g., copper, fibre) or wireless access to its services. The fixed network may support nomadism

38、, but does not support mobility. 3.2.3 mobile network: A network that provides wireless access to its services and supports mobility. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: 2G Second Generation API Application Programming Interface AS Applicat

46、mmendation refers to the IMS concept in ITU-T Y.2021 and as updated in the most recent versions of ITU-T Q.1741 and ITU-T Q.1742. 6 Objectives of FMC 6.1 General objectives of FMC The following points provide the general objectives for FMC: Seamless service operation from the end user perspective ac

47、ross heterogeneous fixed networks (i.e., PSTN, ISDN, PSDN, WAN/LAN/CATV, etc.) and mobile networks (i.e., GSM, CDMA2000, WiMAX, etc.), subject to any limitations imposed by the characteristics of the particular access technology being used. ITU-T Rec. Q.1762/Y.2802 (09/2007) 5 Seamless service provi

48、sioning from the service providers perspective across heterogeneous fixed and mobile networks, subject to any limitations imposed by the characteristics of the particular access technology being used. Generalized Mobility defined in ITU-T Y.2001 is supported in FMC (i.e., terminal device mobility, u

49、ser mobility and session mobility). For a given scenario, different levels of mobility may be needed. Ubiquity of service availability where the end users can enjoy virtually any application, from any location, on any terminal device subject to any limitations imposed by the characteristics of the particular access technologies and terminal devices being used, given that the service has been subscribed. Support of multiple user identifier and authentication/authorization mechanisms. 6.2 Objectives fro
