<p>An access method and a system for cellular mobile communication networks are provided. The method includes the following steps: after a terminal finishes a distance measurement with a base station (BS), the terminal performs a basic capabilities negotiation with the BS. After the basic capabilities negotiation is finished, the BS performs a WLAN Authentication and Privacy Infrastructure (WAPI) access authentication with the terminal. After the access authentication is finished, the terminal performs the subsequent access process to access the cellular mobile communication network. The WAPI access authentication includes the following steps: the terminal sends the BS an access authentication request packet, which includes the certificate of the terminal and the signature of the terminal. After receiving the access authentication request packet, the BS authenticates the signature of the terminal. After a successful signature authentication, the BS includes the certificate of the terminal in a certificate authentication request packet and sends the packet to an authentication server for authentication. After a successful authentication of the certificate of the terminal, the BS sends the terminal an access authentication response packet and negotiates with the terminal for a unicast session key.</p> |
