Device for initialising a communication channel between a subscriber set and a base station in a communication system

摘要

The system comprises a base station 104 in a network with a multitude of subscriber sets 41, where control information is communicated between the base station and the subscriber sets via a radio control channel at a frequency chosen by the base station from a multitude of frequencies. The base station transmits control messages comprising a single network number via the control channel. Timing of the communications transmitted by a subscriber set via a communication channel between a base station and the subscriber set is the subject of a refinement during initial establishment of the communication channel. <IMAGE>
