Multi-network element fusion charging method and system, and charging gateway function

Abstract

The invention discloses a multi-network element fusion charging method, a multi-network element fusion charging system and a charging gateway function. The method comprises that: after receiving call charging stopping requests from a plurality of related network elements in a call process, the charging gateway function generates multi-network element fusion charging data records related to the call process and transmits the multi-network element fusion charging data records to a billing domain; and the billing domain charges the call process according to the multi-network element fusion charging data records. In the scheme, in the process of participating in a call by a plurality of network elements of an Internet protocol multimedia subsystem (IMS), the charging gateway function (CGF) performs charging data record fusion on the plurality of network elements related to the call process and uniformly transmits the multi-network element fusion charging data records to the billing domain to save signaling traffic before the CGF and the billing domain (BD), reduce complexity in the interaction of the network elements of the subsystem and simultaneously avoid the billing domain associating call detail record (CDR) lists of independent network elements again to reduce the complexity of the billing domain.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a multi-network element fusion charging method and system in an IP Multimedia Subsystem (IMS for short), and a charging data gateway functional entity. Background technique [0002] IMS is a next-generation network standard defined by the 3rd Generation Partnership Project (referred to as 3GPP). Its notable feature is the adoption of the Session Initial Protocol (SIP) system, communication and access It can have multiple capabilities such as separation of multimedia service control function and carrying capacity, separation of call and service, separation of application and service, separation of service and network, and integration of mobile network and Internet services. [0003] figure 1 is a schematic diagram of an IMS charging system according to related technologies, such as figure 1 As shown, the whole framework includes User Equipment (UE for short) 101, Prox...

AI Technical Summary

Problems solved by technology

[0020] It can be seen from the above process that when multiple network elements participate in the IMS call process, the CGF needs to issue a CDR bill to the billing center for each network element involved in the call process. The center needs to correlate the CDR bills of all network elements in the call process, and finally perform comprehensive billing. The billing center needs to analyze and correlate the bills of all network elements, and the system complexity is high.
