Method for achieving session content charging

Abstract

The invention discloses a method for achieving session content charging. The method relates to a charging information collecting network element and a CDF network element. The charging information collecting network element has an IBCF, or P-CSCF or ATCF. The method comprises the following steps that a combination type charging property AVP structure for expressing IMS point-to-point session service charging information is expanded in a Diameter protocol charging message structure; in the process of IMS point-to-point session service, the charging information collecting network element records the charging information of a user through the AVP structure and sends the AVP to the CDF network element. The method for achieving session content charging solves the problem in IMS point-to-point session service charging, and content expansion is further easily expanded according to technology development in the future.

Description

technical field [0001] The invention relates to an IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) service charging method in the communication field, in particular to a method for implementing charging for IMS multimedia point-to-point session content. Background technique [0002] IP Multimedia Subsystem (IMS) is composed of all functional entities that can provide multimedia services, including a set of functional entities related to signaling and bearer. The IP Multimedia Subsystem structure includes the following functional units: Call Session Control Function (CSCF), Media Gateway Control Function (MGCF), IP Multimedia Gateway Function (1M-MGW), Multimedia Resource Function Controller (MRFC), Multimedia Resource Function Processor (MRFP), Subscription Location Function (SLF), Exit Gateway Control Function (BGCF), Application Server (AS), and Signaling Gateway Function (SGW). [0003] At present, the existing IMS service charging method can perform offline or on...

AI Technical Summary

Problems solved by technology

[0004] 1) In an IMS multimedia point-to-point session, there may be a scenario where the calling side and the called side of a network element use different signaling plane protocol types, but the current protocol standards cannot be based on the different signaling plane protocol types, or according to Identify and sort billing bills based on the difference in the direction of the call initially requested by the session

[0005] 2) In the IMS network, there may be a scenario where one physical network element entity is virtualized into multiple logical network element entities, and these multiple logical network element entities share one Rf charging interface. Different meta-entities, identify and sort billing bills

[0006] 3) An IMS multimedia point-to-point session may have the scenario of media type conversion (trandcoding) between the calling side and the called side. The operator needs to provide the calling side and the called side of the media plane of the IMS multimedia point-to-point session in the billing bill. media traffic and media quality measurement data on the side, so that it can formulate a more flexible billing strategy, but the current protocol standard is still unable to distinguish the media of the IMS multimedia point-to-point session provided by the calling side and the called side in the billing bill. Flow, media quality measurement data

[0007] 4) After an IMS multimedia point-to-point session enters the call phase, there may be a media switching scenario, but the current protocol standard is still unable to provide the media flow and media quality measurement data of the media plane before and after the media switching in the billing bill, resulting in This prevents operators from being able to formulate more flexible billing strategies based on different media traffic and media quality before and after media switching
