[0055] figure 1 It is a schematic diagram of networking of the terminal equipment access control system provided by the first embodiment of the present invention, which is composed of figure 1 It can be seen that the terminal device access control system provided in this embodiment includes: multiple access devices, and the wireless local area networks of the multiple access devices form a public local area network; wherein, the access devices communicate directly or indirectly through third-party devices to perform Data interaction;

[0056] The access device is used to provide a wireless local area network; after detecting the access request of the terminal device to access the wireless local area network, obtain the device identification of the terminal device, judge whether the device identification is the device identification of the device on the network, and if so, connect the terminal device to the network. The access request is a request initiated by the terminal dev...

[0230] The present invention will be further explained in combination with specific application scenarios and taking the access device as a CPE (Customer Premise Equipment, customer terminal equipment) device as an example.

[0231] With the rapid development of the Internet, CPE equipment has been widely used as a relatively portable communication terminal, but CPE is usually used as equipment in a narrow environment (such as homes, small cafes, etc.), and CPE equipment is usually relatively Independence does not have the characteristics of unified management, especially when accessing multiple users, as long as these users have the authentication information of the current CPE, they can log in. The security is poor, and these authentication information can be changed on the CPE. When a CPE is used for networking, it seems powerless. In view of these problems, this embodiment proposes a method for managing CPE user access based on radius (remote authentication dial in user se...

Abstract

The embodiment of the invention provides an access device, an authentication server, a terminal device access control method and a terminal device access control system, the method comprises the following steps: when it is detected that the terminal device requests to access a wireless local area network according to access parameters of the wireless local area network, acquiring a device identifier, judging whether the terminal device is a registered device, and executing different control operations for the terminal device according to difference of judging results, for example, if the terminal device is the registered device, directly enabling the terminal device to access, and when the terminal device is not the registered device, authenticating the terminal device through the authentication server, and enabling the terminal device to access only if the terminal device passes through authentication. Thus, even if wireless parameters of the access device providing the wireless localarea network are leaked, access of unauthorized terminal devices is denied due to failure in terminal device authentication when the unauthorized terminal devices access to the wireless local area network with the wireless parameters, and a problem of low security of the existing wireless local area network is solved.

Description

technical field [0001] The invention relates to the field of local area network applications, in particular to an access device, an authentication server, and a terminal device access control method and system. Background technique [0002] In real life, there are such application scenarios. In order to meet the needs of users to access wireless LANs such as WiFi, businesses such as hotels and stations will set up multiple access devices. The WiFi provided by these access devices is interconnected and covered to achieve Seamless coverage of the scene. [0003] While this method satisfies the user's access requirements, there will be such a problem. In order to facilitate the user terminal to access WiFi, all access devices use the same wireless parameters such as the WiFi name and password to authenticate the user. The WiFi name and password Once leaked, other personnel can use WiFi wantonly, affecting the use of normal customers in the business, and bringing unnecessary ne...
