Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] in such as figure 1 In the PCC architecture shown, PCRF102 has the functions of policy control decision-making and flow-based charging control; PCEF101 is responsible for service data flow detection, policy execution and flow-based charging functions; AF (ApplicationFunction, application function entity) can be set On the service platform 103, dynamic policy / charging control is mainly performed on IP-CAN (IP Connectivity Access N...

Abstract

The invention relates to the field of wireless communications, in particular to a method for determining a PCRF (Policy and Charging Rules Function), access equipment and DRA (Diameter Routing Agent)equipment. The method comprises the following steps: replacing, by the access equipment, a public network IP address in a request message by an NAT (Network Address Translation) domain according to afirst corresponding relation between a preset IP address and the NAT domain, and sending the request message to the DRA equipment of an agent node to enable the DRA equipment to perform PCRF addressing according to the NAT domain. As the NAT domain of the DRA equipment corresponds to one or multiple public network IP addresses, the DRA equipment in the embodiment of the invention does not need toperform the PCRF addressing according to a "multiple-to-multiple" corresponding relation between the public network IP addresses and a PCEF (Policy and Charging Enhancement Function) host number during NAT domain-based addressing, and the look-up difficulty of the DRA equipment during the PCRF addressing can be reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for determining PCRF (Policy and Charging Rules Function, policy control and charging rule functional entity), access equipment and DRA (Diameter RoutingAgent, routing agent node) equipment. Background technique [0002] In order to provide users with differentiated services, a Policy and Charging Control (PCC) architecture is introduced into the communication network, and its structure is as follows: figure 1 shown. Among them, after the user attaches, a Gx session will be established between the PCEF (Policy and Charging Enforcement Function) 101 and the PCRF 102, and when PCC control is performed, the UE (user terminal) will request through the service platform 103 The message is sent to the PCRF through the Rx session. Only when the Gx session and the Rx session of the same user are associated with the same PCRF, can the PCRF generate a control policy a...
