  • Patent number: 8139539
    Abstract: In a system and method for handoff using a hybrid network, a wireless local area network (WLAN) terminal determines its own position information through communication with a code division multiple access (CDMA) base station and a global positioning system (GPS) satellite, and a cell mapping server obtains information about a WLAN cell where the WLAN terminal is currently located from the WLAN terminal position information, determines information about a cell to which the terminal is expected to be handed off from the current position of the WLAN terminal, and provides the cell information to the WLAN terminal. This allows handoff to be performed without scanning a destination access point, thereby significantly reducing WLAN handoff time.
