Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0030]According to the technical scheme of the present invention, according to the different Tag values ​​of the From and To header field pairs of different terminals in the Dialog (dialogue) of each branch, on the basis of the current bill association field, add or Extend the AVP header field, and add the [From-Tag, To-Tag] value pair in the SIP message packet to the billing information, so as to solve the problem of bill association and bill distinction when multiple terminals answer in the case of parallel fork. The specific instructions are as follows:

[0031] Add a new mandatory AVP to the charging information generated by the network element, defined as Dialog-FlagAVP, and its structure is as follows:

[0032] ::=＊＊＊ >

[0033] [Calling-Party-Tag]

[0034] [Called-Party-Tag]

[0035] Among them: 1) If the Calling-Party-Address ...

Abstract

A method for associating and distinguishing the account bill in the Fork scene. The method includes the steps of : a. sets the information about each fork embranchment responding terminals in the account message transmitted from IMS to CCF; b. CCF collects said account message, if the information of each fork embranchment responding terminals are same, then belongs to the same fork embranchment, otherwise it does not belong to the same fork embranchment. A system for associating and distinguishing the account bill in the Fork scene.

Description

technical field [0001] The present invention relates to the technical field of IMS (IP Multimedia Subsystem), and specifically relates to the charging technology in the IMS. Background technique [0002] IMS is a multimedia service subsystem introduced in the 3GPP R5 (3rd Generation Partnership Project R5 version) stage. According to the separation of access and control, the IMS core network should be connected to various types of SIP (session originating protocol) terminals, including Early IMS (early IMS) terminals and fixed network terminals, such as IAD (Integrated Access Device) terminals. [0003] IMS is composed of network entities that control multimedia sessions. In UMTS (Universal Mobile Telecommunications System), IMS is the core for providing IP multimedia services. The main functional entities of the IMS include: CSCF (Call Control Server), MGCF (Media Gateway Control Server), IM-MGW (IP Multimedia-Media Gateway), MRF (Multimedia Resource Function) and BGCF (Eg...
