A strategy for flexible channel assignment in mobile communication systems

Design concepts and procedure for flexible channel assignment in large-scale mobile radio systems are proposed and discussed. The procedures consist of the analysis process for offered traffic distribution and the transmitter/receiver (TRX) allocation process. The algorithm for the TRX allocation process significantly reduces the total number of TRXs necessary for carrying offered traffic. The number of radio channels necessary for the whole system is derived using these algorithms. In these design procedures, the formidable combinatorics problem of allocation is reduced to a comparatively simple optimization problem. Simple examples applying these algorithms are used for explanation. These algorithms are also effective for the scheduled channel assignment scheme, which is efficient for traffic distributions whose transitions can be definitely estimated
