PACKET CONTROL DEVICE, AUTHENTICATION SERVER, AND RADIO COMMUNICATION SYSTEM

摘要

It is possible to reduce the time required for switching from a first network to a second network. A packet control device (106) includes: 3G authentication server communication means (201) for receiving a report on switching of a terminal switched from a mobile communication network to a WLAN network by communication with the 3G authentication server (108) performing network authentication; terminal address decision means (202) for deciding an address usable by the WLAN network; and WLAN switching management means (204) for allocating an address decided by the terminal address decision means (202) for the terminal specified by correlation of the authentication information contained in the switching report with the authentication information contained in a table managing information on a terminal capable of accessing the mobile communication network and the WLAN network, and switching the transmission destination of the packet via the mobile communication network to the WLAN network.
