[0004] However, the new PCC policy information is issued by the PCRF during the handover process. According to the requirements of the 29274 protocol, the handover message cannot carry the bearer establishment or update process, that is, the PGW handover process cannot simultaneously trigger the bearer creation or update, and the PGW cannot simultaneously Handover process and new PCC policy information are processed. Therefore, the new PCC policy information needs to be cached first, and there are too many special processing branches when processing the cache, which makes the message processing of PGW network elements very complicated and unorganized, resulting in the workload of the staff increase

Embodiment Construction
[0071] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0072] refer to figure 1 , figure 1 It is a schematic diagram of the network topology of the System Architecture Evolution (SAE) of the Long Term Evolution (LTE) network, which can show the interfaces between various devices, such as: Serving gateway (SGW) and PDN Gateway (PGW ) is the interface between S5.
[0073] The description of the Gx interface is as follows:
[0074] The position of the Gx interface in the schematic diagram of the network topology is between the policy charging rule function entity (PCRF) and the policy charging enforcement function entity (PCEF, which is a submodule of PGW), and is used to create and delete PCC information and transmit services face event.
[0075] The functions supported by the Gx in...

The embodiment of the present invention provides a method and device for processing dynamic policy charging control PCC information, the method includes that after the switching process is completed, the packet data gateway PGW receives the reauthentication request RAR message sent by the policy charging rule function entity PCRF ; The RAR message includes new dynamic policy charging control PCC information; the PCRF is used to find new PCC information in the handover process, and generates a RAR message according to the PCC information; PGW uses the new PCC information Perform bearer binding; PGW initiates corresponding bearer processing according to the result of the bearer binding; PGW generates a re-authentication response RAA message for the RAR message according to the result of the bearer processing, and sends the RAA message to the Described PCRF. The invention can make the message flow processing clear, reduce the special processing process inside the PGW, reduce the processing complexity of the PGW, and facilitate the development and maintenance of staff.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method for processing dynamic policy charging control PCC information and a processing device for dynamic policy charging control PCC information. Background technique [0002] With the development of the mobile Internet, there are more and more users of mobile data services, and the traffic is increasing. When users use mobile data services, the user's location information is constantly changing, which requires the billing system to be able to Carry out business-based policy control according to the supplier's policy and user's needs, and can realize the switching of different business data flows. [0003] At present, when the location information of the user UE (User Equipment, user equipment) changes, in the process of sending the handover, after receiving the handover request message, the PGW (Packet Gateway, packet data gateway) sends a message to the PCRF (...
