Problems solved by technology

[0006] However, when the functions of PCEF are distributed to multiple network element devices, that is, there are multiple PCEF nodes, the following problems will arise: how to make PCRF correctly find all PCEF nodes belonging to a certain IP connection of a certain mobile terminal
[0008] The shortcoming of the PCRF using the above method to obtain the IP address information of the second PCEF node connected to the IP is: since the second PCEF node will be switched during the mobile terminal movement process, it is necessary to update the IP address information in the PCRF after the switch. Relevant registration information increases the complexity of the process

[0044] figure 2 It is a flow chart of the PCEF node positioning method according to the first embodiment of the present invention.

[0045] This embodiment describes that when the mobile terminal (UE) is within the coverage of 3GPP, and the 3GPP core network adopts the EPC architecture; in EPC, the interface protocol between S-GW and P-GW is based on PMIP, that is, S-GW The GW and the P-GW establish a PMIP tunnel, and the S-GW includes the second PCEF node, which provides policy decision-making functions related to QoS / bearer, such as establishment of IP bearer, modification of IP bearer, release of IP bearer, etc. And the UE has established a default IP bearer to the service network through the S-GW and the P-GW. If the PCRF decides to provide bearer policy decision and / or charging service for the new service from the UE to the above-mentioned service network (for example, when the PCRF receives a request from the service network to establish a new service), the PCRF will i...

Abstract

A wireless communication network strategy and charging implementing function node positioning method. The method is applied in the PCRF and P-GW wireless communication network containing the 3GPP evolved packet system, the main PCEF node containing partial strategy and charging implementing function exists in the P-GW, and the main PCEF node is connected with the slave PCEF node in the other network element device containing the other part of strategy and charging implementing function through the network, when the P-GW receives the message provided by the first strategy and charging rule transmitted by the PCRF and used to perform bearing strategy and charging control to the mobile terminal service, the IP address of the slave PCEF node is acquired, and the IP address is contained in thefirst strategy and charging rule responding message and transmitted to the PCRF. The adoption of the method of the invention can position the second PCEF node conveniently and accurately when the newservice is established for the mobile terminal and when the bearing strategy and charging control is performed to the existing service.

Description

technical field [0001] The present invention relates to a strategy and charging execution function node positioning method of a wireless communication network, in particular to a 3GPP (3rd Generation Partnership Project, third generation partnership project) evolutionary packet system network strategy and charging execution function node positioning method method. Background technique [0002] 3GPP Evolved Packet System (EPS for short) consists of E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network), MME (Mobility Management Entity), S-GW (Service Gateway, Serving Gateway), P-GW (Packet Data Network GateWay, data network gateway), HSS (Home Subscriber Server, Home Subscriber Server), 3GPP AAA server (3GPP Authentication Authorization Accounting Server), PCRF (Policy and Charging RulesFunction, Policies and charging rule functions), and other supporting network element equipment. Among them, MME is responsible for ...
