Abstract
A radio communications apparatus includes a network position detector for detecting information on the position of the communication device on a radio telecommunications network, a network connection detector for detecting the disengagement of the device from the network, and a controller for controlling the transmission timing of join signals. The controller is adapted to vary a transmission timeout period, upon expiring of which a join signal is sent out, depending on the information about the positions on the network. The radio communications device is thus able to decrease the probability of occurrence of collision to thereby reduce the time taken for reestablishing the network.
