摘要： PURPOSE:To efficiently operate a communication resource without setting a class as required or over by setting a range of quality on request belonging to a call in which a predicted traffic is in existence depending on a threshold level. CONSTITUTION:A quality on request applied to a communication system is received by a caller reception section 3 when a terminal equipment 1 makes dialing, a reception discrimination section 4 makes class discrimination according to the quality on request and implements reception discrimination depending on communication resource of a class dependent communication resource management section 5 and connection call information of a class dependent connection call management section 6. Cell delay quality, cell abort quality and a call loss rate are used to warrant the quality equal to all calls and the quality on request by the call is a maximum speed/mean speed. A traffic distribution warranting the quality on request is obtained based on an estimated traffic by using past statistic traffic information and deduction function. Then a threshold level being a 0 or over is provided to the call traffic and a class is set to the quality on request being traffic in excess of the threshold level.

摘要： PURPOSE:To realize the communication system utilizing effectively a cell by connecting plural communication nodes with a different address with a transmission line and circulating the cell comprising control information and user information through the transmission line. CONSTITUTION:When a cell reaches via a transmission line 1, it is received by a cell reception section 3. When a reception destination of the cell is its own communication node address, the information is transferred to a reception buffer 6 and stored tentatively. The stored information is read by a terminal adaptor section 8 and sent to a terminal equipment 9 as user information. Moreover, the cell reception section 3 transfers the control information of the received cell to a management section 5. The management section 8 checks idle/ busy information of the arrived cell and the information to be sent from a transmission buffer 7 stores into a user information field of the cell when the information represents an idle state and sets the idle/busy bit to the busy state, and sets the reception sender and the reception destination respectively.

摘要： PURPOSE:To easily increase a switchboard scale by letting each exchange module have independently a resource managing function, an exchanging function and a call controlling function, etc., and constituting these exchange modules into building block constitution. CONSTITUTION:A call accepting part Bq receives call origination from a front stage switchboard or a terminal, and transfers call origination information to a call controlling function part Bj. The call controlling function part Bj inquires a resource managing function part Bi about the propriety of the use of the resource of an intermodule coupling mechanism Bf to an outgoing exchange module Bd selected by translating a number. A call setting signal transmitting receiving part Bk sends a call setting signal to the designated outgoing exchange module Bd. The call setting signal transmitting receiving part Bm of the outgoing exchange module Bd receives the call setting signal from an incoming exchange module Bd, and transfers it to the call controlling function part Bo. A call sending part Br sends the call setting signal to the switchboard of a next stage or a remote party terminal.

摘要： PURPOSE:To effectively use intra-network resources such as a transmission line capacity and a buffer capacity by preliminarily generating a resource assignment table for resource management parameters which can satisfy the communication quality prescribed by each service class. CONSTITUTION:An exchange leads out a maximum degree of multiplexing, which can satisfy the communication quality prescribed by each service class, for the traffic (call) having attribute of values T1 and T2. A link capacity is divided by the maximum degree of multiplexing and the result is defined as the assigned resource quantity, and the resource assignment table where this resource quantity is the table value for values T1 and T2 is generated for each service class. At the time of network operation, the resource assignment table corresponding to the service class requested by a call connection request call is retrieved to determine the rate of the assigned resource quantity each time when call connection is requested.

摘要： PURPOSE:To process a packet without limiting traffic by sending the packet of a small delay class with priority normally and when the packet of a small loss class is accumulated in a sending matrix for a long time, sending such a packet with the priority. CONSTITUTION:For a matrix control circuit 170. by the output of a header analyzing circuit 120, the packet of the small delay class to have a severe request to a delay time is read from a memory 140 and outputted with the priority to the packet of the small loss class to have the severe request to a packet abandon rate. On the other hand, when the waiting time of the packet of the small loss class goes over a time T1 to be determined in advance, the control circuit 170 outputs the packet with the priority to the packet of the small delay class. When the waiting time of the small delay class goes over a time T2 to be determined in advance, the packet is abandoned.

摘要： PURPOSE:To suppress the difference in the observation accuracy due to the speed and to eliminate the observation error by setting an observation period for respective calls and observing at the arbitrary section. CONSTITUTION:An observing point of time the is the holding time unit of a fixed length packet and the observation of the traffic on a line is executed by an observing part 10. A counter part 15 holds the number of the packets to arrive in a past observation period time T up to the present time point as an observation value at the counter part 15. A value sum of the counter part 15 at a certain observation point of time shows the number of the arriving packets for the past observation period time from the time point. At a deciding part 16 to judge whether or not the observation result at the observing part 10 exceeds an arriving packet number specified value max in the observation period set to a specified value holding part 18 beforehand, the value sum of the counter part 15 and the value of the specified value holding part 18 are compared in a control part 17 and at the time of sum>msx, a specified value exceeding signal is generated.

摘要： PURPOSE:To eliminate the need for adding function for absorbing fluctuation by temporarily setting the clock of a reception terminal again on a basis of the clock of a transmission terminal at the time of communication start to delay the output start of packet information until time information in a header coincides the time measured by the clock of the reception terminal itself. CONSTITUTION:A call controller 29 in the reception terminal starts a packet decomposition control circuit 44 and a decoder 28 in a packet decomposer 27 by the completion of call setting. If a taken-out packet is the first packet, the packet decomposition control circuit 44 sets the value, which is obtained by subtracting R from a time T in the packet header, to a time (t) of a reception clock 47 and starts the clock. Thereafter, the packet decomposition control circuit 44 waits until the time (t) of the reception clock 47 coincides with the header set time T in accordance with elapse of time. Thus, it is unnecessary to add special functions to repeating nodes in a network.

摘要： PURPOSE:To reduce deterioration of the channel availability caused by a channel dividing loss by changing the number of channels of each channel in response to the traffic fluctuation, etc. of a transmitting device. CONSTITUTION:A channel allocation controller 3 informs a transmitting device to perform rearrangement of channels the head channel number, the number of channels and the allocated channel number of a communication call within a channel block for the channel blocksset before and after the transmitting device rearranges channels. At the transmitting device a central processing circuit 7 sets the transmission gate control data to a transmission gate control circuit 12 and also the transmission buffer control data to a transmission buffer control circuit 5 respectively. Then the control data on the circuits 12 and 5 are switched when a channel rearrangement executing time point is informed from the controller 3.
