<p>In a cell-site base station, a received broadcast message is stored in a memory and traffic channels and a control channel are monitored. If at least one traffic channel, a traffic channel is established and data is read from the memory and transmitted on the established channel to mobile stations. If a call request is placed on the established traffic channel during the broadcast transmission and if the control channel is available, the control channel is established instead of the traffic channel to continue the broadcast transmission. If at least one traffic channel becomes available, the control channel is replaced with a traffic channel to continue the broadcast transmission. For transmitting command messages from the base station to the mobile stations, a broadcast control channel is used. <IMAGE> <IMAGE> <IMAGE></p> |
