Abstract
A method of requesting a communication resource by a wireless communication unit operating in a wireless communication system. The wireless communication system provides for uplink and downlink channels. The method includes the steps of: allocating a dedicated communication channel to said wireless communication unit by a wireless communication serving unit; transmitting a communication resource request message (130) on said dedicated uplink channel by said wireless communication unit (110) to said wireless communication serving unit (120); and transmitting an access allocation message (140) to said wireless communication unit (110) from said wireless communication serving unit (120) on said dedicated downlink channel. A communication system and communication unit are also provided.This provides the advantage that a dedicated channel is used for requesting shared resources thereby avoiding various problems, including clashes, associated with using a random access channel.
