22、 modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates

23、 TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document.

24、-04)63GPP TS 29.335 version 14.0.0 Release 141 Scope The present document specifies the stage 3 of the Ud interface between the Front-Ends (FEs) and the User Data Repository (UDR) in the User Data Convergence (UDC architecture). This 3GPP Technical Specification (TS) specifies the protocol and inter

25、actions between the FE and the UDR for Ud reference point, in particular: - The details of the LDAP protocol that are to be considered - The details of the SOAP envelope that provide support for subscriptions to notifications and notifications about data changes service (S/N operations). The User Da

26、ta Convergence Stage 2 description (architecture and information flows) is specified in 3GPP TS 23.335 10. The UDR data model used with LDAP (i.e. attributes, object classes and directory information tree) is implementation specific and is left outside the scope of 3GPP specifications. For multivend

27、or interoperability between FEs and UDR specific integration projects are needed. Some examples of Ud data models are described in 3GPP TR 29.935 19. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - Refere

28、nces are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GS

29、M document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TR 41.001: “GSM Release specifications“. 3 3GPP TR 21 912 (V3.1.0): “Example 2, using fixed text“

36、purposes of the present document, the terms and definitions given in 3GPP TR 21.905 1 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 1. LDAP Session: starts with LDAP Bind Operation and ends with LDAP U

37、nbind Operation or Notice of Disconnection. Front End: a core network functional entity or service layer entity or provisioning entity that can access user data stored in a unique repository. Front End Identifier: A name that uniquely identifies an FE within the set of all FEs accessing an UDR. Fron

38、t End Cluster: FEs handling the same application may be grouped in clusters to differentiate between them e.g. with regard to geographical location, feature support, vendor, or other characteristics. All FEs within a cluster are treated equally for required purposes (e.g. authorization, notification

39、s, etc.). Application type: The application handled by a FE (e.g. HLR) determines the application type of the FE. The application type is derived from the name indicated by a FE. Front End Cluster Identifier: A name that identifies a cluster grouped with FEs supporting the same application. User Dat

40、a Repository: facility where user data can be accessed stored and managed in a common way. 3.2 Symbols For the purposes of the present document, the following symbols apply: Ud reference point between a FE and the UDR 3.3 Abbreviations For the purposes of the present document, the abbreviations give

For an existing session,

45、UDC messages are exchanged between the FE and the UDR. See figure B.1-1 in Annex B for general LDAP message flows. 5.2 Open Link for a LDAP Session To initiate a LDAP session, a Front-End shall first establish a transport connection with the UDR. The transport connection shall be a TCP connection. T

46、he IP Layer may be secured according to section 8. When IPsec is used, an IPsec connection may support several TCP connections, each supporting a LDAP session. After establishment of the transport connection, the FE shall initiate a LDAP session by sending a LDAP BindRequest message. The establishme

47、nt of the LDAP session shall comply with IETF RFC 4511 8. It shall be done before sending any other LDAP message. FE Identifier or FE Cluster Identifier shall be included in the BindRequest message. The UDR shall support the “unauthenticated authentication mechanism of simple Bind“ and the “name/pas

48、sword authentication mechanism of simple Bind“ in the “simple authentication method“ specified in IETF RFC 4513 16. The UDR derives the application type from the FE Identifier or the FE Cluster Identifier. If the FE provided the Front End Identifier the UDR may also derive the Front End Cluster Iden

49、tifier. NOTE: As security is handled at IP Layer (see section 8), optional security mechanisms (TLS, SASL) described in IETF RFC 4513 16 specification are not required for Ud. 5.3 Close Link for a LDAP Session Termination of the LDAP session may be initiated by the FE by sending an UnbindRequest message or by the UDR by sending a Notice of Disconnection message. The termination of the LDAP session shall comply with IETF RFC 4511 8 5.4 Transactions In order to allow FEs to relate a number of update ope
