Problems solved by technology

[0025] Shortcomings of the prior art: the existing PCC architecture is used to solve the problem of policy and charging control in the existing system architecture of 3GPP, and all data flows (comprising SIP signaling data flow and media data flow) of an AF session only in one For transmission on the IP-CAN session, for an AF session, the mobile user will only be assigned one IP address
The existing PCC architecture cannot solve this situation

Embodiment Construction

[0067] In the SAE system architecture, when assigning different IP addresses to users for an IMS service, which are used for SIP signaling transmission and media data transmission respectively, in order to optimize the routing of user media data, for an AF session, there can be Corresponding to multiple IP-CAN sessions, one IP-CAN session is used for the transmission of SIP signaling data stream, or the transmission of SIP signaling data stream and some media data streams, and one or more IP-CAN sessions Used for the transmission of media data streams. The embodiments of the present invention are not only applicable to roaming scenarios, but also applicable to scenarios where a mobile user changes location in a larger area in the same PLMN. In the embodiment of the present invention, only two IP addresses are assigned to the user in the roaming scenario, one is used for the transmission of SIP signaling data streams, and the other is used for the transmission of media data str...

Abstract

The invention discloses a strategy and charging control processing method, which comprises the following steps: whether the AF dialog is corresponding to more than two IP intercommunication access network IP-CAN dialogs is judged according to application function (AF) dialog information; according to the AF dialog information, the IP-CAN dialog information is obtained; the AF dialog and the IP-CAN dialog are bound; and according to the AF dialog information and the IP-CAN dialog information, corresponding strategy and charging control PCC rule of the more than two IP-CAN dialogs are generated. The invention also discloses a strategy and charging control system and a device. In the embodiment of the invention, operators are enabled to conveniently perform strategy and charging control on grouped data optimized by a router.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a processing method, a switching method, a system and a device for controlling policy and charging of a routing optimization packet data flow. Background technique [0002] In order to ensure the competitiveness of the 3GPP (3rd Generation Partnership Project, third-generation cooperation project) system for 10 years or longer, a SAE (System Architecture Evolution, System Architecture Evolution) work is being carried out within the 3GPP organization. In particular, in order to enhance the ability of the 3GPP system to process rapidly increasing IP (Internet Protocol, Internet Protocol) data services, the use of packet technology in the 3GPP system requires further enhancement. Some of the most important parts of this type of technological evolution include: reduced delay and response time; higher user data rates; enhanced system capacity and coverage as well as reduc...
