摘要： A technique is disclosed, by which it is possible to achieve the reduction of power consumption of each wireless node and to perform efficient access control in wireless communication system. According to this technique, a given period with a beacon transmitted from a gateway (GW) 100 at the foremost position is divided to an active period where each wireless node (P2P tag) transmits and receives a frame and a sleep period where transmitting and receiving of the frames are stopped. Further, the active period is divided to a plurality of timeslots each with a fixed length, and the period is partitioned to sub-periods where each type of a GW, a fixed node (P2P-S tag), and a mobile node (P2P-M tag) can transmit frames respectively. Each of the P2P tags selects a timeslot at random from the period for each type, and after waiting for a waiting period at random at the selected timeslot, it transmits a frame including information to identify the selected timeslot or the waiting period in addition to its own ID.

摘要： Disclosed is a technique which reduces the packet loss and the band consumption for data transfer when a mobile terminal conducts the handover between a fixed base station and a mobile base station for group movement. According to this technique, when an MH (mobile terminal) 320 conducts the handover from a fixed base station (E-LSR 230) positioned at an edge of an access network 200 to a mobile base station (MEB 310) located in a train or the like, a predetermined flag is appended to a frame addressed to the MH in a label switching router (P-LSR 210) positioned at a core network 100 side edge of the access network. The frame having the appended flag is copied in the E-LSR 230. One frame after copied is transmitted directly from the E-LSR to the MH while the other frame after copied is transferred from the E-LSR to the MEB and then transmitted from the MEB to the MH, thus realizing the soft handover.

摘要： There is disclosed an access network system capable of improving throughput even when a single relay device is arranged for different communication routes between an ISP device and a plurality of subscriber terminal devices. In this system, each of the subscribers (111 to 114) and relay stations (105) sets a VLAN so that one VLAN becomes a line. By VLAN-tagging to the packet of the subscriber data, the subscriber data is transferred via the VLAN. The access network system (100) generates MAC address tag information having a destination MAC address indicating the subscriber station which is an edge of the route of the VLAN, a source MAC address indicating the subscriber station corresponding to the route of the VLAN, and a VLAN tag and adds the MAC address tag information to the subscriber data.

摘要： A central processing unit for executing instructions of variable length in which an operand specifier for specifying the addressing mode of an operand is independent of an operation code for ascertaining the kind of an operation and the number of operands. Each operand specifier is formed of one or more data bytes, and has a stop bit flag indicating whether or not the particular operand specifier is the last operand specifier. By adding the stop bit flag, the operand specifier can be shared, and different processing can be executed with an identical operation code. In a case where, when operation code decoding means has provided an output indicative of the last operand, the stop bit flat is not detected in the corresponding operand specifier, the corresponding instruction is detected as an error.

摘要： A data processing system for supporting a virtual memory is disclosed. Prior to the start of main memory write operation, a processor checks to see if a store buffer has a vacant area to store data to be written into a main memory to execute a current instruction. If a page fault occurs during the main memory write operation, the processor continues to store the subsequent write data for the current instruction and the corresponding virtual or logical addresses in the store buffer to complete execution of the current instruction.
