Abstract
A method and system for controlling overload at a network processor in a communications system. Messages relating to a plurality of types of calls, functions or processes (collectively, 'calls') received at a processor seeking access to processor resources are granted normal access when the delay in processing such messages does not exceed threshold values. When such delay exceeds a threshold, messages are blocked in numbers relating to, among other things, the number of messages allowed in a reference interval, message delay, the total number of blocked calls, the number of blocked calls of each type, the number of calls allowed in one or more preceding intervals and preferences between types of calls.
