<p>PROBLEM TO BE SOLVED: To reserve many more radio channel numbers without increasing frequency bands by using a cell multiplex signal resulting from multiplexing communication signal cells each provided with header information including address identifier different from each mobile set for a communication signal between a base station and each mobile set. SOLUTION: A base station controller 20 is connected to a public network PSTN via a wired communication line 50 and a mobile communication exchange 10, and connected to base stations 30, 45 via wired communication lines 60, 65 to conduct call processing with mobile sets 40-42. The base station 80 is connected to the mobile sets 40-42 through radio channels 70, 80, 90 that are label-multiplexed by using the same frequency and the same spread codeνto send/receive communication data. That is, the base station is communicated with the different mobile sets 40-42 by using the cell multiplex signal resulting from multiplexing communication signal cells each provided with header information including destination addresses AD#0-#2 different from each mobile set. Thus, many radio channels can be reserved without using the frequency multiplexing technology.</p> |
