<p>Apparatus and method for reducing collisions on an enhanced access channel in a high bandwidth wireless network during a push-to-talk (PTT) communication between a plurality of user devices. A random delay field is introduced to a set of access parameters and the random delay is generated at each user device when the user devices are ready to transmit an access probe through the enhanced access channel to a base station. At the end of the random delay, the user devices send the access probe through the enhanced access channel to the base station. A maximum random delay field may be set by the base station. ® KIPO & WIPO 2008</p> |
