ADAPTIVE SPECTRUM ALLOCATION METHOD USING SHARING SPECTRUM BETWEEN DIFFERENT OPERATORS IN MULTI-BAND MOBILE COMMUNICATION SYSTEM

摘要

1. TECHNICAL FIELD OF THE INVENTION; The present invention relates to an adaptive spectrum allocation method using spectrum sharing between heterogeneous operators in a multiband mobile communication system.; 2. The technical problem to be solved by the invention; The present invention shares frequency bands individually allocated to each operator in a multi-band mobile communication system as one single spectrum, and maximizes frequency utilization efficiency by adaptively allocating users belonging to other operators according to call rejection rate and traffic conditions. The purpose of the present invention is to provide an adaptive spectrum allocation method using spectrum sharing among heterogeneous operators in a multiband mobile communication system.; 3. Summary of Solution to Invention; The present invention relates to a spectrum allocation method in a multi-band mobile communication system in which frequencies are individually assigned and operated for each service provider. Determining the other station access order according to the call rejection rate; And when the user terminal to which the call was rejected re-requests a call to the base station of the third party vendor, the base station of the third party vendor provides the available frequency to the user terminal according to the priority determined in the step of determining the access point of the other station and the current base station traffic state. Includes an adaptive FA reassignment step to reallocate.; 4. Important uses of the invention;The present invention is used for spectrum allocation in a multiband mobile communication system.;CDMA, multiband mobile communication systems, adaptive spectrum sharing, dynamic spectrum allocation, frequency sharing, spectrum sharing, call rejection rate, FA reallocation
