MOBILE WIMAX NETWORK SYSTEM INCLUDING PRIVATE NETWORK AND THE MOBILE IP TERMINAL PROCESSING METHOD

摘要

A mobile Wi-Max (WiMax) network system including private network and a mobile IP terminal processing method are provided to process the intranet service and the public network core network(CN) service with one private access control router. An initial access processor(211) performs the initial access procedure of the arbitrary Wi-Max terminal requesting the initial access. The mobile IP determining unit(212) determines whether the mobile IP address is set up in the Wi-Max terminal or not. The Wi-Max terminal performs the initial access procedure through the initial access processor. If the IP address is set up in the Wi-Max terminal requesting the initial access through the mobile IP determining unit, the mobile IP processor(213) determines the confirmed Wi-Max terminal as the Wi-Max terminal in which the mobile IP address is allocated. The mobile IP registration procedure of the Wi-Max terminal according to the mobile IP standard is performed. The private Wi-Max terminal determining unit(214) determines whether the corresponding Wi-Max terminal is the private user Wi-Max terminal or not. The IP mapping table(216) maps the mobile IP address and virtual IP address and registers it. It maps the mobile IP address and virtual IP address and the IP mapping table registers. If the corresponding Wi-Max terminal is the private user Wi-Max terminal, the IP mapping processor(215) registers the virtual IP address for accessing to the private network in the IP mapping table.
