Abstract: A server suitable for a vehicle having a first wireless interface providing a connection on a customer basis for local user terminals to the server, to enable access to local content on the server, and a second wireless interface providing a connection to an external mobile network, to enable access to remote content on remote servers.

Abstract: There is provided a terminal that is capable of not sending a useless probe request to detect a stealth access point. The terminal communicates with a normal access point that reports a network identifier and a stealth access point that does not report a network identifier. The terminal includes an access point information accumulating section 103 for accumulating access point information that indicates whether each access point is a normal access point or a stealth access point, a beacon signal detecting section 101 for listening for and detecting a beacon signal, a probe request sending section 105 for sending a probe request, and an access point finding control section 102 for controlling the beacon signal detecting section 101 to detect the beacon signal with respect to the normal access point, and controlling the probe request sending section 105 to send the probe request with respect to the stealth access point.

Abstract: A wireless packet communication system that enables a wireless terminal to move from one wireless LAN to another while maintaining packet communication. The wireless terminal detects the electric field strength of a carrier signal from each base station during at least one back-off period, creates move destination information based on a carrier signal having the greatest electric field strength and the IP address of the currently used base station, and transmits the created Information and IP address to a server. The server writes the IP address of the wireless terminal into an edge router connected to a base station at the move destination in accordance with the information and IP address created by the wireless terminal to ensure that the packet data from a remote party is transmitted from the base station at the move destination.

Abstract: A communication system in which a mobile terminal MT communicates with a home agent HA by way of a cellular communication network and a WLAN includes a processor in communication with the HA and the cellular communication network. The MT communicates with the HA via the cellular communication network and the processor receives handover history information of the MT from the cellular communication network. As the MT moves within the cellular communication network, the processor predicts when the MT will enter an area covered by a WLAN and pre-registers the MT with the WLAN so that when the MT enters the WLAN covered area, the MT can immediately start receiving information from the WLAN. By having a processor perform the pre-registration, the radio resources of the MT are preserved.
