摘要： PURPOSE:To prevent the communication contents from being transferred to a communication opposite party from whom the content is kept a secret by a simple method by comparing the reception security level of the communication opposite party and the information security level on a transmission side and connecting the transmission side with the only communication opposite party having the reception security level which is higher than the information security level. CONSTITUTION:The information security level SL stored in a field 16 is inputted in a comparator 14 via a control line 56, and a reception security level sl and an information security level SL are compared. In the case of (reception security level sl) >= (information security level SL), the logic of a control line 58 becomes 1, the communication opposite party number TN stored in a field 17 via a control line 57 is inputted in an AND line 15 and the communication opposite party number TN is outputted to a control line 59 via the AND circuit 15. The communication opposite party number TN outputted from the control line 59 is outputted to the central control unit, etc., of a communication network or an exchange and a communication is set.

摘要： PURPOSE:To eliminate the need of providing a centralized control center and to construct a communication network by notifying an exchanger on the calling side of regulation information by means by the backword of a call, performing a regulation control and utilizing the feedback control of the exchange on the calling side and on the receiving side. CONSTITUTION:The device consists of a call processing module 101, a congestion detection module 102, a regulation control module 103 and interfaces 104 and 105 between the modules. The congestion control system adopts a decentralized control system. When the congestion is detected, the exchanger on the calling side is notified of the regulation information and actuated, and the change of a regulation amount in the congestion exchanger and the exchanger on the calling side are automatically performed by means of the feedback control, and accordingly, the traffic control is enabled quickly and efficiently. Since a congestion control center is not required, the necessity for the center facilities and their operation management is eliminated and thus, econimical traffic congestion control having econimical efficiency can be enabled.

摘要： PURPOSE:To set the number of lines responding immediately to the traffic by deciding the congestion state of the communications network, providing a regulation control means indicating the start of regulation to an exchange device and a line setting means, automatically calculating the necessary number of lines according to the state of traffic and the state of fault to decide the combination of control to be applied. CONSTITUTION:An entire control part 11 applies a line design technology to calculate the symmetry value of the line from the on-line regulation information and routine information, and to perform the line setting at real time. For example, when a regulation control part 13 performs the regulation start by detecting the congestion against a certain route, the entire control part 11 collects the routine information from a routine control part 12, synthetically deciding them from the other traffic data, network construction, etc., delivering the command to a line setting control part 14 to allocate an empty line to the route under the congestion, and the line setting control part 14 performs a new line setting at the real time. When the line is out of order, a control exchanging the lines by searching the line to the other route with less traffic is performed. Thus, the line setting according to the traffic can be performed.

摘要： PURPOSE:To prevent pressing of a traffic and to control the priority to a desired value by using a holding number Ri of a call kind 1 as a function of resource using number for each call kind and revising the priority of a call kind (i) dynamically in response to the number of use of ressources of each call kinds. CONSTITUTION:When a call kind 1 of a call connection 1 section 1 requires to acquire the resource, the call connection section 1 outputs a call kind (i) to a control line 21, number of use of resources ni of each call kind to a control line 22 and an idle resource number X to a control line 23 respectively. Upon the receipt of call kind (i) and the number of use of resources ni of each call kind, a function calculation circuit 11 calculates the holding number Ri of a call kind (i) according to the programmed function fi in advance and outputs the result to the control line 24. A comparator circuit 12 compares the idle resource number with the holding number Ri and brings the level of the control line 25 to logical '1' in the case of X>Ri and the level of the control line 25 to logical '0' in other cases. The call connection section 1 applies acquisition of resource to the said call.

摘要： PURPOSE:To perform the optimum control by evading over-regulation or under- regulation by providing a regulation control data base, and performing a processing corresponding to the quantity of regulation by the regulation control data base when the incoming number of a call coincides with a regulation candidate number registered at an exchange. CONSTITUTION:The exchange 4 always monitors exchange congestion information, for example, the activity ratio of an exchange processor, etc., and the number of overflow calls from a subscriber, and transfers a representative subscriber number, a slave number, and the exchange congestion information to a traffic congestion control center 11 via a control link 13 when those information and number exceed threshold values. The traffic congestion control center 11 judges it as subscriber congestion with respect to the subscriber 2, and sets 509-9900 that is the representative subscriber number and the slave number 509-9800 to 9855 as regulation numbers to control the congestion of the subscriber 2, and also, sets the common high-order number 509-9 of those regulation numbers as the regulation candidate number. Furthermore, the quantity of regulation is decided, and the regulation information are sent to the regulation control data base 12 via a data link 17.
