A method for allowing new traffic on a wireless data network. A service request is received from a mobile station (,). An effective bandwidth of the service request is estimated (,) using a recursive estimator (,). If there is enough surplus capacity on the wireless data network to accommodate the service request, the service request is granted. In response, a discrete adjustment, based on the effective bandwidth, is applied (,) to the recursive estimator (,).

Method for an admission control function for a wireless data network

The disclosed system is capable of allocating plural subchannels based on user data priority. In one embodiment, after receiving a system parameters such as a current priority level from a base station, a subscriber determines whether to send an access request for plural subchannels. Upon receipt of the access request(s), the system determines from the access request(s) whether to allocate the subchannel(s) to the subscriber. Further access requests are received periodically and scheduled, and when a higher priority message is received, completion of a lower priority message is deferred and the higher priority request allocated. Thus, an improved access procedure is provided accommodating multiple priority requests in an efficient manner. In a further embodiment, the system parameters include persistence/probability values for each service priority level, and each transmitting unit applies the appropriate value for the data priority to be sent in determining when to send an access request.

Method and apparatus for communicating in a wireless communication system

The disclosed system is capable of allocating plural subchannels based on user data priority. In one embodiment, a subscriber determines the throughput it would like and fragments a data packet in that number of service data units, and requests that number of subchannel allocations from a serving base station. Upon receipt of the access request(s), including any priority indicators, the system determines from the access request(s) whether to allocate the subchannel(s) to the subscriber. Further access requests are received periodically and scheduled, and when a higher priority message is received, completion of a lower priority message is deferred and the higher priority request allocated. Thus, an improved access procedure is provided accommodating varying throughput rates with a more robust transfer because of the packet fragmentation and multiple-subchannel transfer.

Method for communicating data in a wireless communication system

A method of data message delivery for single frequency reuse data communications systems wherein the system after attempting a data message delivery on a reuse path and detecting an absence of a data message confirmation reattempts the data message delivery on a non-reuse path where the non-reuse path is successively selected as one of; the reuse path in a non-reuse mode, a last used path, and a registered, as determined by a portable, path.
