Abstract
A high priority system access technique is provided in which an MS () instead of relying on its open loop power level routine to determine its power level for transmission of a system access request uses a higher power level to transmit its access request, such as its RACH preamble. The power level used for transmission of the RACH preamble can be dependent on the particular user and/or in the application (e.g., dispatch, streaming video, etc.). By using a higher power level than the other MSs () operating in the system (), MS () has a higher probability of gaining system access and a channel grant in an expeditious fashion. This priority access technique is very helpful for applications that require quick channel grants.
