Abstract

The subscriber communication system includes a base station in a network with a number of subscriber stations, where control information is communicated between the base station and the subscriber stations over a radio control channel (RCC) at a frequency selected by the base station from a number of predetermined frequencies. The a base station transmits control messages including a unique network number over the RCC. Each subscriber station processes the network number in the control message received over the RCC to enable the subscriber station to process the control message in accordance with whether the subscriber station is in the same network as the base station. The timing of communications transmitted by a subscriber station over a given communication channel between a base station and the subscriber station is refined upon initial establishment of the communication channel.
