Problems solved by technology

[0020] Then, in step 303, when PCRF requests policy information from SPR, it uses a pseudo-identity, and the PCC information of subscribers in SPR is based on real identification, so it is definitely impossible to find the policy information of the corresponding user.
However, for the above problems, the prior art has not yet proposed an effective solution.

Embodiment Construction

[0054] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0055] In order to realize in the PCC framework of WiMAX network, under the situation that SPR and AAA server are separated, query user policy information based on real user identification, a kind of method for obtaining user identification provided by the present invention mainly comprises: in IP-CAN session During the establishment process, the PCRF requests the user's real identification from the AAA server, and the AAA server returns the user's real identification to the PCRF; or, during the establishment of the IP-CAN session, the SPR requests the user's real identification from the AAA server, and the AAA server sends SPR returns the real identity of the user.

[0056] The above-mentioned method for obtaining a user ID will be further elaborated below in conjunction with specific embodiments.

Abstract

The invention discloses a method for obtaining a user identifier and a system for obtaining the user identifier under a policy and charging control (PCC) frame in a worldwide interoperability for microwave access (WiMAX) network. The method comprises the following steps: when an internet protocol-connectivity access network (IP-CAN) conversation is built, a policy and charging rules function (PCRF) entity requests a real identifier of a user from an authentication authorization accounting (AAA) server, and the AAA server returns the real identifier of the user back to the PCRF; or when the IP-CAN conversation is built, a subscription profile repository (SPR) requests a real identifier of the user from the AAA server, and the AAA server returns the real identifier of the user back to the SPR. User policy information based on the real user identifier is realized under the condition that the SPR is separated from the AAA server in the PCC frame of the WiMAX network.

Description

technical field [0001] The present invention relates to the technical field of Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access), and in particular to a method and system for acquiring user identification under the framework of Policy and Charging Control (PCC, Policy and Charging Control) in a WiMAX network . Background technique [0002] The existing Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access) network usually consists of three parts: WiMAX terminal (referred to as terminal, or mobile station / fixed station), access service network (ASN, Access Service Network) and Connect service network (CSN, Connect Service Network), such as figure 1 shown. [0003] Among them, the ASN mainly completes the following functions: completing the Layer 2 (L2) connection of the terminal, transmitting the Authentication Authorization Accounting (AAA, Authentication Authorization ...
