<p>An access terminal and a method for binding the access terminal to an operator are provided. The method mainly includes the following steps. A broadband access server (BAS) receives a packet, encrypts private information in the packet using an agreed encryption algorithm, and then sends the encrypted information to the access terminal through a response packet. The access terminal encrypts the private information using the agreed encryption algorithm, and compares the encrypted private information with the encrypted information carried in the response packet. If the two are different, a dial-up process is ended or a link is removed. The technical solutions of the present invention can effectively prevent the user from using an access terminal provided by the current operator to access networks of other operators, so as to avoid vicious competition between the operators. Moreover, the present invention is simply achieved without changing the networking mode and the user's habit, and has no demand of service distribution.</p> |
