ADAPTIVE SPECTRUM ALLOCATION METHOD USING SPECTRUM SHARING AMONG MULTI-BAND WIRELESS ACCESS SYSTEM, AND SYSTEM CONTROLLING METHOD USING IT

摘要

1. the art that the invention set forth in the claims ; The present invention relates to a multi-band wireless access will adaptive system via a shared spectrum between the frequency assignment method and system using the same control method in a mobile communication system. ; 2. The invention is to solve the technical challenges ; The present invention moves to set the service provided to this to change the call requirements of the users of voice services and low-speed data service in accordance with the time easy, the system-specific shared frequency band in accordance with the real-time user request in a communication system, and the change with time by responding to the call request quantity to occupy the shared frequency band of the other system, to provide an adaptive spectrum allocation and system control method using the same that can improve the spectrum utilization efficiency that is an object. ; 3. The gist of the solution of the invention, ; The present invention according to the spectrum allocation method in a mobile communication system, a base station placed at the same position placing the base stations of heterogeneous wireless systems in the cell service area overlapping; By allocating a part of the fixed allocation of spectrum for each wireless system to share a frequency band, the frequency allocation method comprising: setting a fixed frequency band assigned to a fixed spectrum and a shared frequency band; And the cell area when requesting an user terminal the service in the first to allocate money supply channels and the carrier frequency in a wireless system adaptively to the user terminal, the second if there is an available frequency band of the radio system, the user terminal and a step of adaptive spectrum allocation ever occupy the shared frequency band of the second wireless system. ; 4. important use of the invention ; The invention yiyongdoem like a mobile communication system. ; Adaptive spectrum allocation, frequency sharing, dynamic spectrum allocation, dynamic channel allocation
