Method and device for re-authenticating terminal

Abstract

The invention provides a method for re-authenticating a terminal, which aims to optimize an access process of the re-authentication of the existing WiMAX terminal and solve the problems of relatively slower re-authentication of the existing WiMAX terminal and higher pressure of an AAA server. The method comprises the following steps: sending an authentication start message (namely an EAP-Start message) to an authentication client (such as Supplicant) by firmware (which can be a chip embedded in the terminal such as WiMAX chip); generating an authentication response message and sending the authentication response message to the AAA server by the authentication client; sending a challenge message of a preset algorithm to the authentication client by the AAA server; sending a response message of the preset algorithm corresponding the challenge message of the preset algorithm to the AAA server by the authentication client; and sending a successful authentication message to the authentication client by the AAA server, wherein the authentication response message carries the identification information of the terminal. In addition, the invention also provides a device for re-authenticating the terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically, to a method and device for re-authentication of a terminal. Background technique [0002] The full name of WiMAX is World Interoperability for Microwave Access, that is, global interoperability for microwave access. It is a broadband wireless access metropolitan area network (Wireless Metropolitan Area Network, WMAN) technology based on IEEE 802.16 series standards. A new air interface standard proposed by the frequency band. The basic goal of WiMAX is to ensure the interconnection and interworking of wireless devices from different manufacturers in the access environment of the metropolitan area network. Personal mobile communication services. Compared with other broadband wireless access technologies, WiMAX has the advantages of wide coverage, strong scalability, and controllable quality of service (QoS). [0003] WiMAX is the standard for mobile broadband...

Problems solved by technology

[0016] The purpose of the present invention is to optimize the access process of existing WiMAX terminals in re-authentication, and solve the problems of relatively slow re-authentication of current WiMAX terminals and high AAA pressure. In order to solve these problems, the present invention proposes a The method for the terminal to perform re-authentication includes the following steps: Firmware (which may be a chip embedded in the terminal, such as a WiMAX chip) sends an authentication start message (ie, an EAP-Start message) to an authentication client (such as , Supplicant); the authentication client generates an authentication response message, and sends the authentication response message to the AAA server; the AAA server sends the challenge message of the predetermined algorithm to the authentication client; the authentication client will match the challenge message of the predetermined algorithm The response message of the predetermined algorithm corresponding to the message is sent to the AAA server; the AAA server sends the authentication success message to the authentication client, wherein the authentication response message carries the identification information of the terminal
