specific Embodiment approach

[0080] According to this schematic diagram, the specific implementation is as follows:

[0081] The present invention will be described below in combination with specific processing scenarios.

[0082] In this example, if Figure 5 As shown, the hypothetical scenario is: user A initiates a call to user B, and then user B puts the call on hold, and the session between user A and user B has been established, that is, the Start bill CDR has been generated on each network element .

[0083] Steps 501-507: A continues to call B, initiates B to hold the call, and in the Re-INVITE message, its SDP information contains a=send-only or c=0.0.0.0); AS forwards the Re-INVITE message to the called side ; Before CSCF_A and CSCF_B respectively trigger the AS, mark their respective calling and calling marks in the route field of the Re-INVITE message. Here, when CSCF_A triggers the AS, it marks the calling party mo, and when CSCF_B triggers the AS, it marks the called party mt;

Abstract

The invention discloses an offline charging method and an offline charging system for an IP multimedia subsystem. The method comprises the following steps that: during service charging, a call session control function triggers an application server and carries a node role identification of the call session control function in a session initial message; the application server carries a user role identification of a user for carrying out service in a charging request sent to a charging data function by the application server, and notifies the user role identification to the charging data function; the charging data function generates an application server bill according to the user role identification, and generates a call session control function bill according to the node role identification; and a charging gateway function carries out correlative charging of the application server bill and the call session control function bill according to an IP multimedia subsystem charging identification (ICID) and a calling / called role identification. The offline charging method and the offline charging system can effectively solve the problem of charging correlation on both calling and called sides existing in application server session triggered by the call session control function.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to an off-line charging method and system for an IP multimedia subsystem. Background technique [0002] IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) was first defined in the 3GPPR5 version, it is a system based on IP technology and Session Initiation Protocol (Session Initialization Protocol, SIP) technology, integrating voice, data, mobile and Internet services , whose goal is to integrate the Internet and mobile communication networks. [0003] At present, the traditional fixed-line operators (Fixed-Mobile Convergence) with 3G licenses are more urgent for IMS in the world. The IMS network structure is characterized by access independence, and its business, control, and bearer are separated from each other. [0004] figure 1 Shows the hierarchical structure of the current IMS system. [0005] Such as figure 1 As shown, in the IMS system, the core contro...
