摘要： In packet communications between a mobile terminal and a base station, the mobile terminal checks a priority level of a traffic and judges a type of the traffic, and transmits a reservation signal for a transmission request to the base station when the type of the traffic is a high priority level or realtime type, and does not transmits it when the type of the traffic is a low priority level or non-realtime type, while the base station determines a resource amount to be reserved for packet transmission according to a resource utilization state and the reservation signal for the traffic of the high priority level or realtime type, or an average transmission interval or transmission rate for the traffic of the low priority level or non-realtime type according to margins in remaining resources, and notifies the resource amount or the average transmission interval or transmission rate to the mobile terminal.

摘要： A network system implements paging control in which the control apparatus, upon receiving a packet destined for a mobile terminal, transmits a paging notification packet to a paging area of the mobile terminal, so as to obtain location information of the mobile terminal and to determine a transfer destination of a received packet. The control apparatus is configured to transmit the paging notification packet to a plurality of router devices included in the paging area. Each of the plurality of router devices is configured to transmit a received paging notification packet to a plurality of access points by multicasting. Each of the plurality of access points is configured to transmit a received paging notification packet to the mobile terminal through a link connection by multicasting, when it is judged that an IP address in the paging notification packet is a predetermined IP address.

摘要： A packet transmission system is provided to achieve a higher throughput in downlink packet transmission to a mobile node. When there is a packet call directed to the mobile node, a transmission node in a network in this packet transmission system retrieves information as to a connection point of the mobile node from a distribution location information holder of a home agent. Packets are inputted to a packet distributor situated at the logical location designated by the retrieved connection point information. The packets are then distributed by the packet distributor to radio transmission devices, and are transmitted at once.

摘要： In a state I, a link layer of a mobile host is connected to an access router and a default router is set to the access router such that data packets (P1) and (P2) reach the access router and are routed to a correspondent host. In states II and III, data packets (P3) to (P8) are not transmitted but are buffered. When the mobile host switches the default router from the access router to an access router upon reception of a router advertisement from the access router, processing moves to a state IV and the buffered data packets (P3) to (P8) are transmitted. Since the link layer of the mobile host is connected to the access router and the default router is set to the access router, the data packets (P3) to (P8) reach the access router and are routed to the correspondent host.

摘要： A packet transmission system includes a home agent providing a home link and a home address to a mobile node, one or more access routers, each providing a foreign link and a c/o address to the mobile node, and one or more mobility support routers that relay a packet to the destination between the mobile node and the home agent or a counterpart correspondent node. When the mobile node moves into a new foreign link, the corresponding access router transmits a registration request to the home agent and/or the correspondent node. When acquiring a registration request on the way to the destination, each mobility support router stores an entry having the home address of the mobile node and the c/o address contained in the registration request, and produces and transmits a new registration request updating the c/o address to its own address. When receiving a packet addressed to the home address recorded in the entry, the mobility support router encapsulates this packet to produce a tunneling packet and relays the tunneling packet to the c/o address that is recorded in the entry in association with the home address, thereby correctly forwarding the data packet to the destination.
