The user profile functions support the identified service and control functions in the service stratum, as well as the network access control functions in the transport str

This Supplement provides details concerning user data to be stored in the service user profile functional entity and other functional entities to enable user services and applications.

Keywords NGN, service user data, user data. ii Q series Supplement 56 (04/2007) 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
9、 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, es
10、tablishes 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 necessary
11、standards are prepared on a collaborative basis with ISO and IEC.

26、d elsewhere This Supplement uses the following terms defined elsewhere: 3.1.1 NGN service stratum ITU-T Y.2011: That part of the NGN which provides the user functions that transfer service-related data and the functions that control and manage service resources and network services to enable user se
27、rvices and applications. 3.2 Terms defined in this Supplement This Supplement defines the following terms: 3.2.1 user data: All information that specifies identification, authentication, subscribed services, service provisions, access configuration, location management, routing and charging for the
28、NGN user. Some user data are referred to as permanent user data, i.e., they can only be changed by administration means. Other data are temporary user data which may change as a result of normal operation of the system. 3.2.2 service user data: The user data that is stored, handled and maintained by
29、 the functional entities in the service stratum. 2 Q series Supplement 56 (04/2007) 4 Abbreviations and acronyms This Supplement uses the following abbreviations and acronyms: AGCF Access Gateway Control Function AKA Authentication and Key Agreement AMG Access Media Gateway APL-GW-FE Application Gat

32、e stratum associated with a NGN user which is required to represent the user and to provide subscribed services of the user. The objectives for NGN release 1 are to provide an extensible platform and architecture supporting: multimedia services (including PSTN/ISDN simulation services); PSTN/ISDN re
33、placement support (emulation services); data communication services; public interest aspects (for both multimedia services and PSTN/ISDN replacement support) ITU-T Sup.1-Y. The overall architecture of the service stratum of NGN release 1 is designed to support the above NGN services in ITU-T Y.2012.
34、 In addition, three visualized architectures are designed for more intelligibility and operability, namely, Call Server-based PSTN/ISDN emulation subsystem ITU-T Y.2031 and IMS-based PSTN/ISDN emulation subsystem ITU-T Y.2031 and IP multimedia subsystem ITU-T Y.2021. Except public interest aspects s
35、ervices that should be supported in all architectures, the PSTN/ISDN emulation subsystem is designed to provide PSTN/ISDN emulation services, while the IP multimedia subsystem is focused on offering multimedia services (including PSTN/ISDN simulation services). Q series Supplement 56 (04/2007) 3 Sin
36、ce the three architectures vary in functional entities, service capabilities and supporting user types, which are important factors impacting the organization, storage and invoking of service user data, it is supposed to describe NGN service user data in three categories: user data for Call Server-b
37、ased PSTN/ISDN emulation subsystem; user data for IMS-based PSTN/ISDN emulation subsystem; user data for IP multimedia subsystem. NGN service user data is stored in a set of functional entities of the three architectures. Some user data are referred to as permanent information while some as temporar
38、y information. 6.1 User data for Call Server-based PSTN/ISDN emulation subsystem The basic user data should consist of: subscription, identification and numbering; registration; service and service triggers; core network services authorization. Functional entities In Call Server-based PSTN/ISDN emul
39、ation subsystem, user data are potentially stored in functional entities of SUP-FE, CCF, SPF and AS-FE ITU-T Y.2031. 6.2 User data for IMS-based PSTN/ISDN emulation subsystem The basic user data should consist of: subscription, identification and numbering; registration; location information; servic
40、e sessions; charging; authentication. Functional entities In IMS-based PSTN/ISDN emulation subsystem, user data are potentially stored in functional entities of SUP-FE, CSCFs, AGCF and ASF ITU-T Y.2031. 6.3 User data for IP multimedia subsystem The basic user data should consist of: subscription, id
41、entification and numbering; registration; location and presence information; service sessions; charging; authentication. Functional entities In IP multimedia subsystem, user data are potentially stored in functional entities of SUP-FE, CSCFs and AS-FE ITU-T Y.2021. 4 Q series Supplement 56 (04/2007)
42、 7 User data for Call Server-based PSTN/ISDN emulation subsystem 7.1 Data related to subscription, identification and numbering 7.1.1 User identity The user identity is an E.164 number and stored permanently in the SUP-FE and CCF. 7.2 Data related to registration 7.2.1 AGCF ID The AGCF ID identifies
43、 the AGCF currently serving the user equipment of Call Server-based PSTN/ISDN emulation user. The AGCF ID is stored permanently in the SUP-FE and CCF. 7.2.2 AMG-FE ID The AMG-FE ID identifies the AMG-FE to which the user equipment of Call Server-based PSTN/ISDN emulation user is connected. The AMG-F
44、E ID is permanent data stored in the AGCF. 7.2.3 CCF name The CCF name identifies the CCF allocated to the user when the user is registered to Call Server-based PSTN/ISDN emulation subsystem. The CCF name shall be in the form of a SIP URL IETF RFC 3261. The CCF name is temporary data and is stored i
45、n the SUP-FE. 7.3 Data related to service and service triggers 7.3.1 Data related to value-added service and service triggers 7.3.1.1 Initial filter criteria A set of initial filter criteria are stored for each user, for each application or service that the user request may invoke. Each set of filte
46、r criteria includes the application server address (identifier for AS-FE, APL-GW-FE or legacy IN SCF), priority of the filter criteria, default handling, trigger points and optional service information. The initial filter criteria are stored permanently in SUP-FE and temporarily in the CCF. 7.3.1.2
47、Application server information The SUP-FE may store application server-specific information for each user. This information may include service key, trigger points, and service scripts, etc. The application server information is stored permanently in one or more AS-FE, APL-GW-FE or SCF. 7.3.1.3 Serv
48、ice-related data The service-related data is used by some value-added service logic. The service-related data is stored permanently in one or more AS-FE or SCF. 7.3.2 Data related to supplementary service and service triggers 7.3.2.1 Service subscription information The service subscription informat
49、ion is used to indicate which supplementary services are subscribed by a user. Q series Supplement 56 (04/2007) 5 The service subscription information is stored permanently in either the SPF or SUP-FE. When stored in the SUP-FE, this information may be downloaded to the SPF and stored temporarily. 7.3.2.2 Service-related data The service-related data is used by some supplementary service logic, such as call forwarding number. The servic
