[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 invention provides a method and device for processing policy control and charging (PCC) information. The method comprises the steps that after handover process is completed, a packet gateway (PGW) receives a re-authentication request (RAR) message sent by a policy and charging rules function (PCRF), wherein the RAR message comprises new PCC information and the PCRF is used for finding the new PCC information in the handover process and generating the RAR message based on the PCC information; the PGW conducts bearing binding on the new PCC information; the PGW starts corresponding bearing processing according to a bearing binding result; the PGW generates a re-authentication answering (RAA) message for the RAR message according to a bearing processing result and sends the RAA message to the PCRF. By the adoption of the method and device for processing the PCC information, the message processing procedure is clear, inner special processing procedures in the PGW are reduced, the PGW processing complicity is reduced, and development and maintenance by workers are facilitated.
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, the PGW (Packet Gateway, packet data gateway) receives the handover request message, and charges to the PCRF (Policy and ...
