Abstract: 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.

Abstract: A method and system for accessing to a network through public equipment are provided. The method includes: after an access service node (ASN) receives a network access request message from a user on public equipment, the ASN sending the network access request message to an authentication center (AC), wherein, the network access request message comprises at least the user's account and password; the AC verifying validity of the account and the password, if the verification is passed, sending the user's access identifier (AID) to the ASN; and after the ASN receives the user's AID, the ASN sending the user's AID to the public equipment, the public equipment taking the user's AID as a virtual AID and using the virtual AID to send and receive user's messages. By the present invention, users who access to the network through the public equipment can be tracked and traced effectively.

The method includes: after receiving a network access request message transmitted by a user over a public device, an Access Service Node (ASN) transmitting the received network access request message to an Authentication Center (AC), wherein, the network access request message comprises identifier information of the user; the AC initiating inquiring to an Identity Information Center (IIC) according to the identifier information of the user, and authenticating the legal validity of the user according to an inquired result, and if the authentication passes, transmitting the user's Access Identifier (AID) to the ASN; and after receiving the user's AID, the ASN sending the received AID to the public device, and the public device using the user's AID as a virtual AID, and using the virtual AID to transmit/receive packets of the user.
