A billing method in IP multimedia subsystem network

Abstract

The present invention discloses an accounting method in an IP multi-media subsystem network, which includes two steps. Firstly, when the trigger condition of accounting is satisfied, a unification network element constructs a message of unification accounting information, which is then sent to an accounting data processing function; and secondly, according to the received message of unification accounting information, the accounting data processing function constructs corresponding accounting telephone bills of each of the network elements contained in the unification network element or corresponding unification accounting bills of the unification network element. By providing a syncretic accounting method in the IP multi-media subsystem network, the present invention simplifies the accounting processing logic, and as a result, when the network elements on the control layer of the IP multi-media subsystem network are unified, the flow between the network elements and the accounting data processing function is greatly reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a charging method in an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network. Background technique [0002] IMS includes three layers in the network element structure: bearer layer, control layer and service layer. Among them, the network elements included in the control layer are: S-CSCF (Serving Call Session Control, serving call session control function), P-CSCF (Proxy Call Session Control, proxy call session control function), I-CSCF (Interrogating Call Session Control, Query call session control function) and BGCF (Breakout Gateway Control Function, border gateway control function). [0003] As shown in Figure 1, in the service processing process of the IMS network, the above-mentioned network elements generate corresponding ACR (Accounting Request, charging information) according to the pre-configured charging trigger conditions, and transfer these charging information ...

AI Technical Summary

Problems solved by technology

[0006] 1. Multiple network elements are physically integrated, so the data source that generates billing data is also shared. In this case, the billing function is still processed separately according to each network element, which increases the processing complexity;

[0007] 2. In the case of the integration of network elements, each network element still sends its own ACR, which does not effectively reduce the message flow of the Rf reference point, thereby reducing the transmission cost
