Method for realizing policy and charging rule decision

Abstract

The core of the method is that when uniform triggering decision-making condition for roaming subscriber and not roaming subscriber is satisfied, using interacted information between application serverand PCRF unit of strategy and charging rule decision-making function determines result of arbitration corresponding to strategy and parameter of charging rule service for roaming subscriber / not roaming subscriber; and result of arbitration is transferred to access equipment. Through the said uniform triggering decision-making condition for roaming subscriber and not roaming subscriber, the invention makes PCRF carry out decision-making for roaming subscriber / not roaming subscriber at same occasion; moreover, the invention lowers complexity of equipment as well as decision-making cost.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing policy and charging rule decision-making. Background technique [0002] The connection schematic diagram of the user equipment accessing the IMS network through a specific access gateway is shown in the attached figure 1 shown. [0003] figure 1 In the IMS network, when AF (Application Server) and AGW (Access Gateway) are combined, it is necessary to make local decisions on user policies such as QoS (Quality of Service), charging rules and other business parameters, so as to provide users with corresponding access into the service. [0004] At present, the specific implementation process for making decisions on user policies and charging rules is shown in the attached figure 2 And attached image 3 shown. figure 2 In the roaming scenario, the IMS network makes decisions on user policies and charging rules, image 3 In the non-roaming ...

Problems solved by technology

[0025] From the above description of the process and the cooperation sequence of each functional unit, it can be seen that because the timing of PCRF making decisions on roaming users and non-roaming users is different, the processing flow of AF and PCRF making decisions on roaming users and non-roaming users is different. The upper service layer such as the application layer of AF and the policy decision-making layer of PCRF need to perceive the roaming attributes of users, and carry out different decision-making processes according to different roaming attributes, which increases the complexity of the decision-making process and increases the complexity of the application layer and policy decision-making layer. design complexity, which increases the implementation complexity of specific equipment, and ultimately leads to high decision-making implementation costs
