摘要： PURPOSE:To realize regulation immediately responding to the actual occurring status of a call by issuing an instruction to an outgoing exchange by the operations of an outgoing connection regulation rate decision means, a regulation release judging means, a congestion factor ground limitation judging means, an outgoing congestion/incoming congestion judging means, and a total quantity distribution means by using the tabulated number of outgoing calls. CONSTITUTION:When the number of outgoing calls and congestion information are inputted from each exchange, they are received with the information reception part 41 of a congestion controller 40, and a regulation data extraction part 49 extracts a regulation code and a regulation area from the congestion information, and stores them in a storage part 403, and identifies the exchange in the regulation area, and outputs the instruction for each outgoing exchange to an instruction transmission part 50. The number of outgoing calls is tabulated at an outgoing call number tabulation part 42, and is stored in a storage part 401. A regulation quantity is decided at a regulation quantity decision part 46 based on regulation data in the storage part 403. Thereby, it is possible to realize the regulation immediately responding to the actual occurring status of the call.

摘要： PURPOSE:To prevent confusion of a network without releasing a number requiring restriction by deciding restriction command information based on the congestion state at the restart of a congestion controller and resetting the information to an exchange without release of the restriction. CONSTITUTION:A restriction number management memory decoding device section 8 receiving a start from a congestion control restart processing section 1 sets a control restart processing period to start a timer having a restart processing period for the control restart processing period. On the setting of the congestion control restart processing period, the timer is started and the content of a counter counted for the time set by the timer is checked to discriminate whether or not the period reaches the congestion control restart processing period. when the period is within the restart processing period, congestion information is received from a congestion information reception section 7 to discriminate the restriction start and to decide the restriction quantity and the content is set to a restriction number management memory. Thus, the content of the restriction number management memory is used as an initial value, the content of all restriction number management memories of all exchanges is commanded to a control command section 2.

CONSTITUTION:A central control unit CP and a control processor CCP are provided at a congestion controller 20, and the transmission of congestion information C from congestion exchanges 22-27 to the congestion controller 20, and that of regulation information R from the congestion controller 20 are executed via a common line signal device CSE. The total quantity of calls is outputted to a distribution decision part 33 and a relative quantity decision part 35, and the distribution decision part 33 decides the distribution quantity to the relay system exchange, and informs it to the relay system exchange of each controlled system periodically. The regulation rate is informed from a relative quantity instruction part 36 to each relating subscriber system exchange periodically. In such a way, it is possible to perform the regulation utilizing the connecting performance of the incoming side exchange at its maximum even when a large number of outgoing side exchanges exist.

摘要： PURPOSE:To enable a system to meet diversified restriction requirements by deciding an alpha combination ratio (r) between prescribed adjacent restriction rates alphaA, alphaB in which a weighting mean value of both prescribed adjacent restriction rates alphaA, alphaB is a required restriction rate alphaX when the restriction rate alphaX being a median of the two prescribed adjacent restriction rates alphaA, alphaB is on request. CONSTITUTION:When a connection request is concentrated onto a subscriber 2 accommodated in an exchange 11 and congestion takes place in the exchange 11, a restriction exchange decision section 41 decides exchanges I2-In to be restriction objects and a restriction rate decision section 42 decides a required restriction rate alphaX to be 98%, then the restriction exchange decision section 41 informs the restrict object exchanges I2-In to a high restriction rate generating section section 44 and the restriction rate decision section 42 informs the required restriction rate alphaX=98% to the high restriction rate generating section 44. Moreover, the high restriction rate generating section 44 finds the combination ratio (r) between prescribed adjacent restriction rates alphaA=95% and alphaB=100% adjacent to the required restriction rate alphaX=98% informed from the restriction rate decision section 42 and each exchange 1 executes the designated restriction rate alphaF by using a dialing restriction section 11.

摘要： PURPOSE:To prevent congestion at an incoming side from being generated and to prevent excessive control from being applied on traffic intensity, by distributing the traffic intensity of upper limit to an outgoing side exchange or an adjacent exchange based on the traffic intensity possible to be processed by a congested exchange or the traffic intensity possible to be processed by a congested subscriber, and limiting call connection. CONSTITUTION:A controller 13 in a traffic control device 3, when receiving congestion information, retrieves the traffic intensity of upper limit between the outgoing side exchange 1 and a congested area from a memory device 19, and informs respective traffic intensity of upper limit to each outgoing side exchange 1 via a signal device 18, a signal line 22, etc. The outgoing side exchange 1 receiving the traffic intensity of upper limit controls traffic for the congested area so as not to exceed the traffic intensity of upper limit by a controller 11. Furthermore, the traffic control device 3 monitors the exchange 2 in which the congestion is detected and the state of the outgoing side exchange 1, and when a congested state is completed, informs the release of control to the outgoing side exchange 1.

摘要： PURPOSE:To prevent the possibility of reducing a traffic for priority calls due to a widespread increase in the quantity of traffic of nonpriority calls by comparing respectively a call loss rate of each call type and an average using frequency of a resource with respective threshold values and increasing/decreasing the call holding frequency in response to the result of comparison. CONSTITUTION:A call loss rate of each call type is measured by a call loss rate measuring circuit 35 of a holding line number change control section 1, compared with a threshold value stored in registers 31, 32 by comparators 37, 38, the average use frequency of the resource of each call type is measured by an average use line number measuring circuit 36 and compared with a threshold value stored in registers 33, 34 by comparators 39, 40. The result of comparison of the call loss rate and the average line use frequency is outputted from control lines 57-60, logical values of the control lines 57, 59 are ANDed by an AND circuit 41, logic values of the control lines 58, 60 are ORed by an OR circuit 42, the result is outputted to a line holding control section 2 by control line 61, 62, in which the quantity of an idle resource to be held is increased or decreased.
