Abstract
A system implements a method of allocating a mobile communications device, such as a mobile end station, to packet channels, such as packet control channels within a cell. A mobile communications device identifies for access a packet channel by executing an algorithm, such as a hashing algorithm. The mobile communications device then reads a loading message broadcast for that packet channel. If the loading message indicates to the mobile communications device that another packet channel or PCCH should be sought, the mobile communications device tunes to a beacon frequency and reads information for each packet channel or PCCH broadcast at the beacon frequency. The mobile then tunes to a suitable channel. The processing to select a suitable channel is accomplished in the mobile communications device, thereby relieving other system elements, such as the mobile data base station (MDBS) from carrying out that processing and reducing the information traffic on overloaded channels.
