Abstract

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.
