3、asers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Publications shall not in any respect preclude any member or non-member of TIA from manufa

Neither shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically or internationally. TIA DOCUMENTS TIA Documents contain information deemed to be of technical value to the industry, and

10、 defines a transport protocol for use in the IP multimedia (IM) Core Network (CN) 2 subsystem based on Diameter. 3 The present document is applicable to: 4 - The Sh interface between an SIP AS and the AAA. 5 - The Sh interface between an SCS and the AAA. 6 Whenever it is possible this document speci
11、fies the requirements for this protocol by reference to 7 specifications produced by the IETF within the scope of Diameter. Where this is not possible, extensions to 8 Diameter are defined within this document. 9 2 References 10 The following documents contain provisions, which through reference in
12、this text constitute provisions of 11 the present document. 12 References are either specific (identified by date of publication, edition number, version number, 13 etc.) or non-specific. 14 For a specific reference, subsequent revisions do not apply. 15 For a non-specific reference, the latest vers

Unless
21、otherwise specified, the procedures (including error handling and unrecognised 24 information handling) are unmodified. 25 Note: The MSISDN represented in this document is similar to the MDN in 3GPP2. 26 5 Use of the Diameter base protocol 27 The same clarifications of section 5 of 6 shall apply to
22、the Sh interface. An exception is that the 28 application identifier for this application is defined in chapter 6. 29 6 Diameter application for Sh interface 30 This clause specifies a Diameter application that allows a Diameter server and a Diameter client: 31 - to download and update transparent a
23、nd non-transparent user data 32 - to request and send notifications on changes on user data 33 The Sh interface protocol is defined as an IETF vendor specific Diameter application, where the vendor is 34 3GPP. The vendor identifier assigned by IANA to 3GPP ( http:/www.iana.org/assignments/enterprise
24、-35 numbers) is 10415. 36 The Diameter application identifier assigned to the Sh interface application is 167772152 . 37 6.1 Command-Code values 38 This section defines Command-Code values for this Diameter application. 39 Copyright Telecommunications Industry Association Provided by IHS under licen
