<p>A method for access control in a wireless network having a base station and a plurality of remote hosts includes the optional abilities of making dynamic adju stments of the uplink/downlink transmission ratio, making dynamic adjustments of the total number of reservation minislots, and assigning access priorities by message cont ent type within a single user message stream. The method of the invention further provides for remote wireless host paging and for delayed release of active chann els by certain high priority users in order to provide low latency of real-time packets by avoiding the need for repeated channel setup signaling messages. In the preferre d embodiment, there are N minislots available for contention in the next uplink fr ame organized into a plurality of access priority classes. The base station allows m access priority classes. Each remote host of access priority class i randomly picks one contention minislot and transmits an access request, the contention minislot pic ked being in a range from 1 to N i where N(i+1) < N i and N 1=N. In an alternate embodiment of a method for access control according to the present invention, ea ch remote host of access priority class i and with a stack level that equals 0, the n transmits an access request with a probability P i where P(i+1) < P i and P1 = 1 .</p> |
