Abstract

Competition between subscriber stations attempting to access reverse channels in response to Temporary Equipment Identifier (TEI) messages is limited by requiring the subscriber stations to wait for a predetermined amount of time. The time delay is selected on the basis of a random number and a factor based upon the number of TEI messages broadcast. The method for determining response opportunities for subscriber stations also includes a back-off phase at the first stage. The time delays to the defer phase is based upon a random period of time and a predetermined maximum based upon the time needed for the microslots containing a TEI message.

Claims

1. A method of controlling wireless subscriber station responses to Temporary Equipment Identifier (TEI) messages in a wireless communication system having at least one base station for controlling a communication stream broadcast to said wireless subscriber stations, said method comprising the steps of:

(a) dividing said communication stream into a plurality of segments;

(b) dividing said segments into a plurality of blocks;

(c) placing all pending TEI messages for a base station in a first block in each said segment in a predetermined order for transmission by said base station on a forward channel; and

(d) assigning on a reverse channel a block corresponding to each said TEI message transmitted on said forward channel, whereby each subscriber station receiving an associated TEI message responds only in said block assigned for said corresponding TEI message.

2. A method of controlling wireless subscriber station responses to Temporary Equipment Identifier (TEI) messages in a wireless communication system having at least one base station for controlling a communication stream broadcast to said wireless subscriber stations, said method comprising the steps of:

(a) dividing said communication stream into a plurality of segments;

(b) dividing said segments into a plurality of blocks;

(c) placing all pending TEI messages for a base station in a first block in each said segment in a predetermined order for transmission by said base station on a forward channel; and

(d) assigning a block on a reverse channel corresponding to each TEI message transmitted on said forward channel for response by each subscriber station associated with each said TEI message, wherein each said block on said reverse channel begins after a time delay starting from said TEI messages on said forward channel, where the time delay comprise a random number and a number of TEI messages broadcast on said forward channel.
