Document Type and Number:
Japanese Patent JP2004528761
Kind Code:
A
Abstract:
A mobile device roams between homogenous or heterogenous wireless networks while maintaining a communication connection with a home network server for the mobile device. A gateway system for a wireless local area network (WLAN) includes gateway servers and manages roaming of a mobile device between homogenous wireless networks. The gateway system maintains a secure connection to a home gateway server for the mobile device while the mobile device roams between homogenous WLAN's. A network gateway manages roaming of a mobile device between heterogenous network systems. The network gateway obtains an access identifier from another heterogenous network system so the mobile device can roam to the other heterogenous network system while maintaining its connection to the home network gateway for the mobile device.
