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

Embodiment Construction

[0027] FIG. 1 and FIG. 2 have been described in the background technology, and will not be repeated here.

[0028] Referring to Fig. 3 and Fig. 4, a charging method in an IMS network comprises the following steps:

[0029] Step 1: When the charging trigger condition is satisfied, the integrated network element constructs an integrated ACR message, and sends the integrated ACR message to the CDF.

[0030] Wherein, the charging trigger condition may be that the combined network element receives a confirmation response to the session invitation request message sent by other network elements. The ACR message constructed by the integrated network element includes the configuration mode of the integrated network element and the types of network elements included in the integrated network element. Among them, the setting method of the integrated network element is represented by the NE-Integration-Flag field, and the type is an enumerated value. The value of this field is Separated-...

Abstract

The invention discloses a billing method in an IP multimedia subsystem network, which comprises the following steps: 1. When the billing trigger condition is satisfied, a combined network element constructs a combined billing information message, and the combined billing The information message is sent to the billing data processing function; 2. The billing data processing function constructs the billing bills corresponding to each network element included in the unified network element according to the received unified billing information message or The integrated billing bill corresponding to the integrated network element. The technical solution of the present invention provides a converged charging method in the IP multimedia subsystem network, which simplifies the charging processing logic, so that when the network elements of the IP multimedia subsystem network control layer are integrated, the network elements and charging data Traffic between processing functions 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 ...
