Abstract: A method for controlling an overload in a hybrid full electronic switching system, capable of maintaining a stable service condition for an overload control interval and realizing a priority control depending on the type of call by sorting an overload occurring in the system into an overload associated with processors adapted to execute services in a centralized manner and an overload associated with processors adapted to execute same services in a distributed manner and thereby automatically calculating numbers of calls to be accepted respectively for control intervals for two kinds of overloads in different control manners. The method includes two different control procedures respectively applied to a case wherein a reduction in overload can be carried out in a processor involving the overload and a case wherein a reduction in overload can be carried out by limiting services to be executed in other processors.
