Techniques are provided for controlling overload conditions using two values; an acceptance rate fraction allowed value and an occupancy fraction allowed value. The inventive techniques allow quick response to the sudden onset of overload conditions, are robust enough to be used when processor speeds are increased and compare favorably to known techniques.

Methods and devices for providing fast and robust overload control

The invention provides a telecommunication system that allows communication between a circuit-based wireless telephony network and a packet-based Internet telephony network without requiring access to the Public Switched Telephone Network. The system includes a circuit-based wireless telephony network providing wireless access to the system, a packet-based Internet telephony network providing Internet telephony access to the system, and a base station gateway controller for providing an interface between the wireless telephony network and the Internet telephony network. The invention further provides methods for facilitating communication between a first device, the first device being a packet-based Internet telephony network based device, and a second device, the second device being a circuit-based wireless telephony network based device, by facilitating connection of a call from the first device to the second device, without requiring access to the public switched telephone network.

Internet protocol based wireless call processing

Overload conditions affecting a processor of a network switch or the like are substantially eliminated, and the processing of traffic is gradually allowed to increase, by inserting, and then monitoring one or more probes which are placed into a queue of the processor. During a given measurement interval, if the number of probes exceeds a threshold then an overload condition exists. This condition is subsequently reduced using 'multiplicative decrease' techniques. Conversely, if the threshold is not exceeded and there is little or no chance an overload condition can quickly reappear, traffic is allowed to once again be processed gradually using 'additive increase' techniques.

METHODS AND DEVICES FOR PROVIDING EARLY DETECTION, CONTROLLED ELIMINATION OF OVERLOAD CONDITIONS AND THE RETURN OF A CONTROLLED LEVEL OF TRAFFIC AFTER SUCH CONDITIONS HAVE BEEN SUBSTANTIALLY ELIMINATED
