<p>A telecommunication system 20 is provided in which communication devices 3-1, 3-2, 3-3 selectively receive and store network information broadcast by a base station 5 over a beacon channel, e.g. cognitive pilot channel (CPC), based on the communication device's current position, speed and heading, and on route data relating to transport routes that are in the vicinity of the communication device 3-1, 3-2, 3-3. The network information relates to specific geographic localities, or meshes 10, and each communication device 3-1, 3-2, 3-3 stores network information from received messages if the network information relates to geographic regions 10 in to which the communication device 3-1, 3-2, 3-3 is deemed likely to move. Thus, the need for a communication device 3-1, 3-2, 3-3 to obtain and store network information from each sequential broadcast they are capable of receiving, which includes a large quantity of redundant information, is avoided.</p> |
