METHOD AND SYSTEM FOR ACCESSING NETWORK ON PUBLIC DEVICE

摘要

A method and a system for accessing a network on a public device are provided. The method includes: after receiving a network access request message transmitted by a user through a public device, an access server (ASN) transmits it to an authentication center (AC), wherein the network access request message includes the user identifier information; the AC initiates a query to an identifier information center (IIC) according to the user identifier information, verifies the validity of the user according to the query result, if it is verified to be valid, the AC transmits the user AID to the ASN; after receiving the user AID, said ASN pushes it to the public device, consequently the public device uses the user AID as the virtual AID, and utilizes said virtual AID to transmit/receive user packets. The effective tracking and source tracing for the user accessing a network with a public device can be performed by the present invention.
