摘要： A mobile IP data communication system is provided, which is capable of preventing dropouts of packet addressed to the mobile station at the time of switching the packet control station as a result of movement of the mobile station. A packet on an IP data connection that is used by the above-stated mobile station is forwarded to a next packet control station from a previous packet control station of the mobile station. The order of packets is correctly maintained by executing a process that a packet delivered to the next packet control station from the access router while the forwarding is in progress is buffered and a forwarding packet is put through ahead of such buffered packet or is forwarded only up to a time point when a packet from the access router is delivered.

摘要： A wireless communication system comprises a relay system including a plurality of relay devices and a plurality of wireless terminal devices. Each relay device transmits control information to the wireless terminal device which is registered in the own relay device, and each wireless terminal device selects, based on the control information received from the relay device which registers the own wireless terminal device, a channel which is currently able to relay a communication among channels respectively allocated to the relay devices to establish a communication between the wireless terminal devices. Each relay device acquires information configuring the control information via a communication line and causes a downlink signal wirelessly transmitted by the own relay device to synchronize with a communication signal, and each wireless terminal device maintains, when shifting a channel for communication to another channel, a synchronized state established in a channel prior to shifting.

摘要： When no synchronization signal is transmitted over a system bus (115), a master repeater is arbitrarily selected from a plurality of repeaters (1112 to 111n), starts transmitting a synchronization signal over the system bus (115), and transmits information to the system bus (115) in synchronization with the synchronization signal. Other slave repeaters transmit information to the system bus (115) in synchronization with the synchronization signal transmitted by the master repeater.

摘要： Plural repeaters (1111 to 111n) are connected one another via a system bus (115), and each of which detects the state of another repeater by checking a signal transmitted over the system bus (115). When stopping the operation of home repeater (e.g., the repeater (1111)) which performs relaying process among wireless terminal devices (TA) to (TH), a secondary repeater (e.g., the repeater (1112)) set beforehand detects that the home repeater breaks down as the secondary repeater becomes unable to detect the signal over the system bus (115). The secondary repeater responds to the detection and bears the relaying process instead of the home repeater.

摘要： Before software for a routing protocol in a second wireless terminal receives a routing packet between a first wireless terminal and the second wireless terminal that are both included in an ad hoc network, stability determining software determines whether or not a link between the first wireless terminal, which is the source of the routing packet, and the second wireless terminal is stable. When the link is determined to be stable, the software for the routing protocol in the second wireless terminal processes the routing packet. This allows building of a route using only a stable link between adjacent nodes.
