Embodiment Construction

[0030] The present invention will be further described in detail through specific embodiments below in conjunction with the accompanying drawings.

[0031] see figure 1 , the network entities involved in the present invention include: an authentication server, a base station and a terminal; the steps and processing flow of the present invention are as follows:

[0032] 1. After the base station and the terminal complete the access authentication defined in the 200810027930.0 patent "A Secure Access Method for Wireless Metropolitan Area Network" through the authentication server, the authentication server side records the identity of the terminal and the access base station and their corresponding relationship, and the base station Perform business communication with the terminal.

[0033] 2. During the communication process, if the authentication server considers that the identity of a certain terminal is invalid, or the administrator determines that a certain terminal is an ...

Abstract

The invention relates to the technical fields of wireless communication network and network security, in particular to a method and a system for a WMAN (wireless metropolitan area network) entity exiting from a network. The method of the invention comprises the following steps that: a terminal accesses a base station on the network side after passing the identification of an authentication server, and the authentication server records the IDs of the terminal and the base station and corresponding relationship thereof; a service communication is carried out between the base station and the terminal; the authentication server revokes the certificate of the terminal; the authentication server sends a 'notice information for terminal exit' according to the recorded local IDs of the terminal and the connected base station and corresponding relationships thereof; the base station removes the service connection with the terminal to be exited from the network, and interrupts the service communication; and the base station sends a 'response information for terminal exit' to the authentication server. In the invention, when the ID of some terminal of the wireless metropolitan area network fails, or some terminal is set as an illegal user by a manager, the method and the system of the invention can make the terminal timely exit from the communication network so as to ensure the safety ofthe communication network.

Description

technical field [0001] The invention relates to the technical field of wireless communication network and network security, in particular to a method and system for a wireless metropolitan area network entity to withdraw from the network. Background technique [0002] As an important development direction of wireless access technology in the future, wireless metropolitan area network has attracted widespread attention from all walks of life. However, safety issues have always restricted its further promotion and development. IEEE 802.16d defines an authentication protocol based on the public key encryption algorithm (RSA) and digital certificates, which can realize the authentication of the base station BS to the user station BS. The patent "A Secure Access Method for Wireless Metropolitan Area Network" (hereinafter referred to as WMAN-SA) with application number 200810027930.0 provides a secure access method for wireless metropolitan area network. In the process of authent...
