17、 present document. Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction This edition of TS 101 878 differs from previous editions in the following key areas: I

18、t has been modified to technical report format. Only textual descriptions of the capabilities are given serving as requirements for the definition of the service capabilities in meta-protocol using semi-formal tools (UML, ASN.1, SDL where appropriate). Service capabilities have been added to better

19、support harmonization with the service suite of UMTS. Attribute names have been reviewed for consistency and presented in plain English (i.e. no programming constructs are used). ETSI ETSI TR 101 878 V5.1.1 (2004-02) 6 1 Scope The present document, specifies the requirements for the range of service

20、 capabilities necessary to implement the services identified in TR 101 301 1. Service capabilities are invoked either singly or in combination by independent applications to construct recognized or novel communication services. The requirements expressed in the present document apply to all TIPHON-c

21、ompliant products and are realized in the service capability meta-protocols specified in TS 101 882 2. 2 References For the purposes of this technical report (TR) the following references apply: 1 ETSI TR 101 301: “Telecommunications and Internet Protocol Harmonization over Networks (TIPHON) Release

22、 3; Release Definition; TIPHON Release 3 Definition“. 2 ETSI TS 101 882: “TIPHON Release 5; Protocol Framework Definition and Interface Requirement Definition; General“. 3 ITU-T Recommendation E.164: “The international public telecommunication numbering plan“. 4 ETSI TS 123 228: “Digital cellular te

26、cal description which, when combined with a commercial arrangement, specifies a service service capability: specified function that is used either alone or in combination with other service capabilities to realize a complete service application NOTE: A single service capability may be used in more t

27、han one service application.

28、k QoS Quality of Service SDL Specification and Description Language SIP Session Initiation Protocol SpoA Service point of Attachment UML Unified Modelling Language UMTS Universal Mobile Telephony Service VPN Virtual Private Network 4 Service capability model 4.1 Groupings Service capabilities are gr

29、ouped according to the information they manipulate. Analysis of the suite of services required for the support of UMTS-IMS (ETSI TS 123 228 4) and examination of the current provision of those services in the ISDN and the Internet for SIP: RFC 2543 5 and ITU-T Recommendation H.323 6), suggest that t

30、he following groupings of service capabilities are required: Profile: the information and actions required to support operations on the user profile, e.g. registration and authentication. Call: the information and actions required for the establishment, modification, and clearing of a multi-media co

31、nnection between two (or more) users, e.g. call setup and call release. Bearer: the information and actions required for control of connection based service domain operations, e.g. create and join. Media: the information and actions required to enable communications payload encoding and characteriza

32、tion, e.g. allocate media encoding. Message: the information and actions required for control of message handling in the service domain, e.g. storage and retrieval. Event handler: the information and actions required to capture events and trigger responses to those events. 4.2 Other entities in the

33、model 4.2.1 TIPHON User The TIPHON user is an entity, generally outside of the TIPHON model, that initializes and terminates transactions such as telephone calls. NOTE: Although there are signals required to be sent to the user these do not form capabilities as defined in other parts of the present

34、document. Therefore other than recognizing the existence of the TIPHON user as an entity in the system that uses service capabilities no further specification of the TIPHON user is given. ETSI ETSI TR 101 878 V5.1.1 (2004-02) 8 5 Profile service capabilities The profile group contains those service

35、capabilities required to examine, establish or modify data relating to the provision of services against a named user. 5.1 Profile data element 5.1.1 Profile The profile contains the following data elements: Current location of the user. Current status of the user, e.g. busy, reachable, not-reachabl

36、e. The identity of the user to whom the profile refers (may be considered as profile owner). Authentication data. Specific details of this element are to be found in TS 102 165-2 7. A list of services to which the user can be attached. For each service in the list of services there is also a “servic

37、e descriptor“ element that defines additional elements specific to the service: Service name: - Identifies the service. Service status: - Indicates the status of each service (may be different from the overall status found in the “Current status“ element). Service authorization: - Used to verify the

38、 authorization of the user to use the service. Service provider identity: - Indicates the identity of the server providing the service (the identity of the Service point of Attachment (SpoA). Service specific parameters: - Additional data maintained in the profile that may be used to shape how the s

39、ervice is hosted (and may be used to populate bearer or call descriptors when combined in a particular application). An example may be the “forwarded to number“ information for call forwarding services. 5.2 Service capabilities 5.2.1 Register The register service capability allows a user to activate

40、 the profile and to request the provision of a specific service at a specific location. If successful the user receives service attachment credentials including the identity of the SpoA. 5.2.2 Attach The attach service capability allows the user to attach to a service provider using credentials rece

41、ived during registration. ETSI ETSI TR 101 878 V5.1.1 (2004-02) 9 5.2.3 Authenticate The authenticate service capability formally validates the identity of a user or service provider. 5.2.4 Get user status The get user status service capability allows an authorized user to query the current status o

42、f a user (the requesting user or another). 5.2.5 Deregister The deregister service capability terminates the user registration. 5.2.6 Transfer The transfer service capability moves a users profile from one location to another. 5.2.7 Authorize The authorize service capability is used to establish a u

43、sers permission to use a specified service. 5.2.8 Set user status The set user status service capability allows a user to change the current status of a user profile (where the status may take a number of values including Available, Do-not-disturb, Not available). 5.2.9 Interrogate location The inte

44、rrogate location service capability returns the current location maintained in the profile belonging to the user identified as its owner. 5.2.10 Update location The update location service capability updates the current location maintained in the profile belonging to the user identified as its owner

45、. 5.2.11 Update service status The update service status service capability modifies the service status where the service status may take values including available and unavailable. 5.2.12 Add service to profile The add service to profile service capability adds a service to the profile of the user.

46、 5.2.13 Remove service from profile The remove service from profile service capability removes a service from the profile of the user. ETSI ETSI TR 101 878 V5.1.1 (2004-02) 106 Call service capabilities 6.1 Overview The call group contains those service capabilities required to manage an end-to-end

47、connection between two parties, or between many parties, where the topology of the connection may be point-to-point, point-to-multipoint, broadcast and/or point-to-multipoint. 6.2 Call attribute definitions 6.2.1 Call Identity A call identity is assigned when a call is established and is used as a u

48、nique identifier of the call in subsequent operations. The call identity may include additional attributes to qualify the identity (e.g. operator verified, user supplied). 6.2.2 Call descriptor The call descriptor identifies and specifies the call using the following attributes: Call Type: - Variati

49、on of simple call type that may have extended or modified behaviour. Called User Identifier: - Identity of the called party. May be of numeric, alpha or alphanumeric format. Calling User Identifier: - Identity of the calling party. May be of numeric, alpha or alphanumeric format. Identity Presentation Restriction Indication: - Indicator of whether the calling party identity should be offered to the called party Priority: - Priority to be used for call processing/retention. Used, for example, in emerge
