Method and apparatus for establishing a communication link

A method and apparatus whereby a communication unit (10) transmits a first communication channel request signal at a first power level. If a communication link with a base site (12) is not established within a predetermined period, the communication unit transmits a second communication channel requ...

Zusammenfassung:	A method and apparatus whereby a communication unit (10) transmits a first communication channel request signal at a first power level. If a communication link with a base site (12) is not established within a predetermined period, the communication unit transmits a second communication channel request signal at a second level which is higher than the level of the first communication channel request signal. This process may be continued for a predetermined number of times or until a communication link is established. Thus, the probability that a nearby base site, rather than a more distant base site, grants the communication channel is greatly enhanced.
