A method for realizing network access control

Abstract

This invention provides a method for realizing control of network access including: a network access device receives a request message transmitted from a network terminal to determine the access position information of the terminal according to the information carried in the message and authenticates said network terminal only according to the access position information of the terminal and controls network access to it, which authenticates a network terminal according to its access position information directly not according to the name of a user and ciphered codes and can get on-line information of network terminals, besides, it can generate related information of user names and ciphered codes automatically so management of network terminals becomes more flexible.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing network access control. Background technique [0002] With the rapid development of computers and computer communication networks, it has become an important part of people's work and life to use computers to surf the Internet and carry out information exchange in the network. [0003] Computer network terminal users can access the Internet through broadband, dial-up, etc. When network terminal users access the Internet, they can be authenticated and allowed to access the network after passing the authentication; they can also be directly allowed to access the network without authentication. [0004] The authentication of network terminal users is generally based on the user name information input by the network terminal user, such as user name and password. The user name can be used as the account information of the network terminal user to a...

Problems solved by technology

[0007] With this method of accessing the Internet without authentication, network operators do not authenticate network terminal users because they are monthly or yearly subscriptions, so network operators are relatively weak in monitoring network terminal users Know when the network terminal user starts to surf the Internet, when to stop surfing the Internet and the traffic of the network terminal user during the period of surfing the Internet, etc.

Therefore, although this way of accessing the Internet does not need to authenticate the user name and password of the network terminal user, it is still not applicable to the above-mentioned hotel environment.
