Method, system and apparatus for expanding policy and charging control rules

Abstract

The invention discloses an expansion policy and charging control rule method comprising that a policy control and charging rule function device (PCRF) generates the policy and charging control rule containing an expansion seven-layer analytical filtrating rule, and transmits the rule to a policy and charging execution function device (PCEF) to execute. The invention also discloses an expansion policy and charging control rule system comprising a PCRF and a PCEF; as well as a PCRF. The method of the invention realizes the transmission of the policy and charging control rule containing the seven-layer analytical filtrating rule from the PCRF to the PCEF, so that the user visiting position PCEF can be executed according to the policy and charging control rule containing the seven-layer analytical filtrating rule of the user ownership PCRF, the policy and charging control is accurately and fully implemented and the network appliance resource is saved at the same time of convenient centralization management.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, system and device for expanding policy and charging control rules. Background technique [0002] The telecommunication network is an operable network. Therefore, it is necessary to control the services in the network and the resources used by the network in a timely, accurate and comprehensive manner. Policy and charging control (PCC, Policy and Charging Control) is one of the important contents. one. [0003] figure 1 It is a schematic diagram of an existing PCC architecture. Such as figure 1 As shown, the existing PCC system includes an application layer functional entity (AF, Application Function), a policy control and charging rule functional entity (PCRF, Policy Control and Charging Rules Function), and usually set in a gateway (GW, Gateway) Policy and Charging Enforcement Function (PCEF, Policy and Charging Enforcement Function), offline charging system and ...

AI Technical Summary

Problems solved by technology

[0035] The first problem is that when the UE is roaming and the visited PCEF (V-PCEF) requests the home PCRF (H-PCRF) for policy and charging control rules through the visited PCRF (V-PCRF), the H-PCRF The policy and charging control rule information predefined on the V-PCEF may not necessarily be saved. At the same time, since the existing Gx interface cannot transmit policy and According to the policy and charging control rules saved by V-PCEF and H-PCRF at the same time, the policy and charging control of business data flow can be carried out, or only the policy and charging control rules based on IP5 tuple filtering rules can be executed to control the business data. Flow execution policy and charging control, therefore, when the UE is in a roaming situation, policy and charging control cannot be accurately and comprehensively implemented

[0036] The second problem is that because the Gx interface cannot transmit the policy and charging control rules containing extended layer 7 parsing and filtering rule information, such policy and charging control rules can only be configured on the PCEF and saved on the PCRF at the same time When it is necessary to use such rules for charging, PCRF controls PCEF to execute the corresponding rules by sending the relevant information of such rules

With the increase of user personalized features, each user may have different feature configurations. If the same policy and charging control rule information is saved on PCEF, PCRF, and SPR, the policy and charging control rules are modified according to the user's personalized settings. The billing control rules need to be modified at the same time, so it is not convenient for unified management; at the same time, because the policies and billing control rules with different personalized settings need to be saved for each user on the PCEF, PCRF and SPR, it will cause a waste of network resources
