Abstract
A base station (10), in a radio communication network having at least two telephone lines (111 to 11n) and a plurality of radio telephone sets (121 to 12m), includes radio transceivers (131 to 13k) capable of selecting one of a control channel and a plurality of communication channels. A producing arrangement (16, 141, to 14n) is coupled between the radio telephone lines and the radio transceivers for producing, in response to a first arrival signal arriving at one of the telephone lines, a first call signal which is sent by a first selected transceiver through a first selected channel towards the radio telephone sets. The first selected channel is selected from the idle channels of the communication channels by a selecting arrangement (16 and 17). Responsive to a second arrival signal arriving at another of the telephone lines while the first call signal is sent through the first selected channel, the producing arrangement adds a channel code of a different one of the idle channels to make the first selected transceiver send the first call signal and the channel code of the different one of the idle channels over the first selected channel. In this manner, traffic is reduced on a control channel and the base station can rapidly respond to an arrival signal which arrives while the base station is sending a call signal.
