摘要： The present invention discloses a technique for avoiding a signal collision in a wireless medium to improve communication throughput. According to this technique, in a radio communication system composed of a plurality of radio communication devices in such a manner that other radio communication devices exist within the communication area of a radio communication device, a given radio communication device is assigned a time slot periodically so that it can access the wireless medium in the time slot at higher priority than the other radio communication devices. This is achieved as follows: The radio communication device monitors the wireless medium, detects other radio communication devices operating within the communication area of the radio communication device, and divide communication time on the wireless medium into time slots of equal width according to the number of other radio communication devices. Then, each radio communication device selects one of these time slots so as not to share the selected time slot with any other radio communication device, and uses a waiting time shorter than those of the other radio communication devices to access the wireless medium in the selected time slot.

摘要： A technology is disclosed for reducing the number of encapsulations required when MAP forwards a packet to a mobile node which is layered within mobile networks, with mobile networks nested and multiple mobile routers chained behind MAP (Mobility Anchor Point). When a node 420 with Address A wants to send a packet to a node 450 with Address D, the node with Address A inserts a list of immediate addresses into the packet. The list includes a node 430 with Address B and a node 440 with Address C, and the destination address of the packet is set to a next hop destination Address B. The node with Address B receives the packet and swaps the destination address with Address C described in the list of immediate addresses. Similarly, the node with Address C processes the same swapping process, and then the packet reaches the node with Address D.

摘要： According to the present invention, connection can be always maintained between the mobile node and the access router, and disruption of on-going transport session can be prevented by making effective use of two architectures (hierarchical and mesh architectures). The mobile nodes 1000-1, 1000-2 and 1000-3 are attached to the access router 1100-1. When the mobile node maintains link layer connectivity with the access router, it is in the hierarchical mode, whereas when the link layer connectivity is lost, it enters the mesh mode. In the mesh mode, the mobile node attempts to establish virtual link layer connectivity with the access router through other nodes by using mesh network protocol such as MANET. In the mesh mode, the packet is capsulated between the mobile node and the access router when the mobile node and the peer 1400-1 communicate with each other.

摘要： A mobility condition determination unit, provided in an MIP controller that manages moving of a communication node, obtains and examines various conditions that have occurred as the communication node is moving, selects an appropriate HoA (e.g., the home address of an MN1) for the current connection situation, and transmits, to a multihoming controller, a notification indicating that a set of the selected HoA and a CoA constitutes appropriate addresses to be used. Upon receiving the notification from the mobility condition determination unit, the multihoming controller transmits, to the MIP controller, an address (Addr2) consonant with the received HoA, and the MIP controller performs packet communication using the HoA or the CoA consonant with the address.

摘要： A technology is disclosed for reducing the number of encapsulations required when MAP forwards a packet to a mobile node which is layered within mobile networks, with mobile networks nested and multiple mobile routers chained behind MAP (Mobility Anchor Point). MAP 120 manages the binding information between RCoA and LCoA for each of lower-level nodes and grasps the prefixes of each of lower-level mobile routers, for example, the prefix of mobile network 104 of MR 140 or the prefix of mobile network 106 of MR 142. For example, MAP 120 informs MR 140 of the prefix of the mobile network 106 and the binding information between RCoA and LCoA. In this way, MR 140 can grasp a next forwarding destination of the packet transmitted from MAP 120 to MN 150, and the packet can be reached at MN 150 unless the packet is encapsulated multiple times.

摘要： A technology is disclosed for achieving fast and reliable handover. According to this technology, in the network composition where a network coverage area of the cellular base station 105 and network coverage areas of plural WLAN AP (Wireless LAN access point) 110, 115, 120 and 130 overlaps, the roaming mobile node (mobile terminal) 100 stores the listened beacon information from each WLAN AP. The mobile node can promptly perform the handover procedures without waiting for listening to the next beacon by acquiring the beacon information of WLAN AP which is a handover target from the stored information at the instant of determining to do handover to a new WLAN AP. Furthermore, the mobile node can store information on stability of the network connection if it would be connected to each WLAN AP, and determine which WLAN AP is suitable for a handover target by considering the stability.

摘要： A technology is disclosed for providing the global connectivity to the mobile node which is connected to the mobile access router forming the mobile network. According to the technology, it is possible for the mobile node 1000-1 to acquire the global address of the access router (the mobile access router 1200-1) the mobile node is connected through the local fixed router 1100-1. For example, the mobile node sends a Binding Update message which a special marking is embedded, or the mobile node sends a special packet. When the mobile access router receives the message or packet sent from the mobile node, it learns from the received message or packet that the mobile node does not know the primary global address of the mobile access router, and then it informs the mobile node about its primary global address.
