6、service access Summary This Supplement specifies the (Session level) information and computational model of the Consumer-Retailer reference point. It provides information and computational specification for service access defined in Signalling and Protocol Framework for an Evolving Environment (SPFE
7、E). The information and computational specifications are described in informal and formal description languages such as Interface Definition Language (IDL). Source Supplement 28 to ITU-T Q-series Recommendations was prepared by ITU-T Study Group 11 (1997-2000) and approved under the WTSC Resolution
8、5 procedure on 3 December 1999. Keywords Access, computational model, IDL, information model, ODP, reference point, session. Q series - Supplement 28 (12/1999) i FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The
9、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 Telecommunication Standard
10、ization Conference (WTSC), 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 WTSC Resolution 1. In some areas of information
11、technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELL

36、act object which represents the generic information required to establish and support access between two domains. 3.2 User Domain Access Session (UD-AS): An object managed by the user and representing the collection of capabilities and configuration that the user employs to contact a provider. Q ser
37、ies - Supplement 28 (12/1999) 1 3.3 Provider Domain Access Session (PD-AS): An object managed by the provider and created when the user becomes a recognized, identifiable entity with specific capabilities and data within the provider domain. 3.4 Provider Service Session (PSS): A central view of the
38、service session, including all members and any additional provider information and logic necessary to execute service requests and maintain the session. 3.5 Usage Service Session (USS): A session members (e.g. an end-users) customized view of a service. 3.6 Domain Usage Service Session (D-USS): An a
39、bstract object which represents generic information required to establish and support a service between two domains for an associated session member. 3.7 User Domain Usage Service Session (UD-USS): Functionality and information present in an end-user domain, e.g. a consumer domain, to support the us
40、age service session and allow the end- user to interact with the service. 3.8 Provider Domain Usage Service Session (PD-USS): Functionality and information present in a provider domain (e.g. retailer, third party provider) to support the usage service session in a usage provider role. 3.9 Domain Usa

Q series - Supplement 28 (12/1999) 3 5.1 Sessions, Services and Domains This subclause presents the information model as related to session related services2. As a session related service may extend over multiple domains, which are treated as busi
48、ness administrative domains, it is useful to model the service as an aggregation of one or more domain services, where each domain service represents a part of a service confined to a single domain. A session is an instance of a service. Just as a session may represent an instance of a service, a do
49、main session represents an instance of a domain service. Domain sessions may interact to establish services extending over multiple domains. Figure 5-2 shows the relationship between domain, service and session objects. A session related service is an aggregation of other session related services and domain services. Each domain service is instantiated by one domain session, which is established in and managed by its associated domain. A domain session may be bound to another domain session via a domain session binding, which represents the dynamic information used
