Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0045] figure 1 It is a flowchart of a method for associating policy control and charging control sessions provided by the present invention. figure 1 The methods shown include:

[0046] Step 101, PCEF obtains PCRF, wherein the PCRF is used to establish the PCRF used by the Gx session of the user equipment;

[0047] Step 102, the PCEF sends the PCRF corresponding to the user equipment to the PA.

[0048] In the method embodiment provided by the present invention, when there are multiple PCRFs and no DRA equipment is deployed, the PCEF selects the PCRF suitable f...

Abstract

The invention provides a policy and charging control session association method and device. The method comprises the following steps of: obtaining a policy and charging rule function PCRF through a policy and charging enforcement function PCEF, and sending the PCRF corresponding to user equipment to a policy agent, wherein the PCRF is used for establishing a Gx session of the user equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for associating policy control and charging control sessions. Background technique [0002] In order to provide users with differentiated services, the PCC (Policy and Charging Control) architecture is introduced in the network, and the policy and charging rules function PCRF (Policy and Charging Rules Function) through the interface Rx and the operator's IP The business network is connected to obtain business information; the PCRF is connected to the gateway device PGW (Packet DataNetwork Gateway, PDN Gateway) of the packet data network through the Gx interface, and is responsible for initiating the establishment of IP bearer to ensure the service quality Qos (Quality of service) of business data. And carry out billing control. Among them, the PGW is responsible for the execution of policies and charging rules, which is the PCEF (Policy and Charging Enforce...
