摘要： When packet sending and receiving apparatus 21 sets a connection, timing control apparatus 22 generates a timing information Tf as the packet is dispersed equivalently. Timing control apparatus 22 notices the timing information Tf to packet sending and receiving apparatus 21 and base station 3. Packet sending and receiving apparatus 21 carries out a packet generating processing in accordance with a frame offset value which is indicated by the timing information Tf. Therefore, the packets in which a packet transmission timing is averaged in a packet transmission period arrives to packet multiplex apparatus 23. Consequently, it is possible to decrease a waiting time of the packet multiplex transmission. Therefore, it is possible to use efficiency a transmission link L1, while being satisfied the required service quality.

摘要： A traffic control unit and a traffic control method are provided. They carry out, in a first shared resource (like a radio base station in a mobile radio network) of a network including besides the first shared resource, a second shared resource (like a transmission path between a radio base station and a local switch) and a local switch, which are shared by a plurality of users, traffic control of data to be transmitted to the local switch through the second shared resource. This makes it possible to positively achieve the traffic control, and to prevent the shared resources in the network from being wasted. Appropriate control is implemented by carrying out, for data taking place in a burst mode at a period proper to the data, traffic control such that a cumulative transmission volume in a traffic monitoring period determined by taking account of the proper period does not exceed an allowed transmission volume based on a traffic rate.

摘要： A timing controller (22) generates timing information Tf when a packet transceiver (21) sets up a connection so that packets may be evenly dispersed, and informs the packet transceiver (21) and a base station (3) of the timing information (Tf). The packet transceiver (21) generates a packet in accordance with a frame offset value specified by the timing information (Tf). Therefore packets arrive at a packet multiplexer in a packet transmission period at averaged timings. The waiting time of the packet multiplex transmission is shortened. Therefore, a transmission link (L1) can be efficiently used while satisfying the service quality demanded.

摘要： A multiplex system for multiplexing packets into ATM cells to be transmitted, which can implement effective use of channels corresponding to irregular traffic qualities in services with various types of quality conditions in an actual environment. In response to a connection establishment request (S402), current required bandwidths B1, ..., Bm are changed to B'1, ..., B'm by adding the new connection, which causes bandwidths X1, ..., Xm which are assigned to the channels to be changed. When the desired bandwidth including the requested connection is less than an available bandwidth of the corresponding channel, an assigned bandwidth change processing (S406) is activated to assign new bandwidths in accordance with desired bandwidths. The bandwidth assignment change is carried out by changing ratios of extraction rates of packets from the buffers in the multiplex system.

摘要： A concrete circuit configuration is proposed of a multiplex transmitter for loading a standard ATM cell with multiplexed micro-frames which are each shorter than the standard ATM cell. The input micro-frames are delivered to a distributor (504) in the input order through an interface (503). The distributor (504) distributes the input micro-frames using distributing information input. The distributing information accords with the service condition of each connection or micro-frame. An extracting circuit (506) selects buffers in accordance with predetermined buffer selection logic. A cell cancellation monitor circuit (508) relinquishes micro-frames exceeding cell tolerable time periods T2-1 - T2-m. A multiplexing processor (507) transfers the cell or a idle cell to a sender (511) in accordance with the cell transfer timing of the sender (511).
