Consolidation method for manifold billing data records in IP multimedia sub-system

Abstract

The utility model discloses a comprehensive approach for multiplex charging data record in the IP multimedia subsystem; the charging is achieved by combining the redundant fields and sending the charging data records of every network element to the account domain. The charging data records sent to the account domain are comprehensively manipulated by the charging gateway of the IP multimedia subsystem; the public field in the charging data records of each network element associated with the called side or the calling side is merged by the charging gateway, and the charging data record files combined by making segmented records of the public fields and the special fields of each network element are sent to the account domain. By adopting the utility model, the communication expenditure of the CDR file transfer between the CGF and the BD can be reduced, the handling burden of the BD is eased, and integrated charging information can be provided to the network operators to implement a more reasonable and accurate charging pattern.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a comprehensive method for recording multiple billing data in an IP multimedia subsystem. Background technique [0002] In order to support the universal mobile telecommunications system (Universal Mobile Telecommunication System, referred to as "UMTS") network in the bearer, IP Multimedia Subsystem (IP Multimedia Subsystem, referred to as "IMS"), the charging function of each layer, the UMTS network monitors the resources of each layer in real time usage, thereby detecting related billing events. [0003] In an IMS network, each network element generates a charging data record (Charging Data Record, CDR) according to its own role in a session and available session information. There are 7 network elements that can generate charging information in the IMS network: [0004] Serving Call Session Control Function (Serving Call Session Control, S-CSCF); [0005] Proxy...

AI Technical Summary

Problems solved by technology

[0013] From the above description of the prior art, it can be seen that using the prior art, it is difficult to implement flexible charging schemes for services in the IMS network, which cannot meet the requirements of different charging principles for the establishment of IMS sessions and the use of session resources, and for a session Flexible charging requirements for differentiated charging for various media or services with different Quality of Service (QoS)

Moreover, the CDR generated by the charging data function CDF for a single IMS network element in an IMS session does not contain all the information of the session. After these CDRs are sent to the billing domain BD, BD receives all the IMS network elements from the same session After generating the CDR file, it is necessary to associate and merge the charging information of multiple network elements in a session, and the processing burden will be heavy
