A method and system for accessing a network over a public device are provided in the present invention. The method includes: a user inputting an Access Identifier (AID) and authentication information over the public device, and initiating a network access request; after receiving the network access request, an Access Service Node (ASN) transmitting the received network access request to an Authentication Center (AC) to authenticate validity of the User's AID information, and forwarding a network access response returned by the AC to the public device; and after the public device receives the network access response, if the User's AID information is authenticated by the AC to be valid, the public device using the User's AID as a virtual AID, and using the virtual AID to transmit/receive messages of the user.. Utilizing the uniqueness of the user AID within the whole network, the present invention achieves that a user accesses a network over a public device, and can achieve effectively tracking and tracing the user accessing the network over the public device. |
