Being the system which controls the congestion which is generated with the congestion control system and the telecommunication network which possesses congestion

摘要

PROBLEM TO BE SOLVED: To preferentially pass a call type, having a higher priority order from a call type having lower priority order, while alleviating the congestion of a congestion unit and to prevent excess restrictions for a divided loss due to restrictions of each call type.;SOLUTION: When congestion occurs in the exchange, a line or the like of a communication network, a control amount of the call to be passed to the congestion unit (30) is distributed to the restriction executing exchange 1 and each call type by a restriction number-of-calls distributor 5. In the exchange 1, a call for passing one call is decided, as a call of own call type or a call of a call type having higher priority order than that of the own call type in a restricted passing time interval of each call type for the control amount of each call type by a number-of-calls density priority sharing controller 2 which has a restriction deciding unit 3 and a registration table 4 for priority order according to call-type.;COPYRIGHT: (C)2002,JPO
