Abstract:
PURPOSE: A resource management system and a method thereof in a communication system are provided to efficiently use frequency band in a plurality of systems by share of usable frequency band. CONSTITUTION: System information is transmitted and received between a CE(Coexistence Enabler)(140) and a DIS(Coexistence Discovery and Information Server)(110). A plurality of systems uses a usable frequency band through coexistence and frequency share in a first frequency band.
Abstract:
PURPOSE: A resource management system in a communication system and a method thereof are provided to use available frequency in the frequency bandwidth which is being used, thereby enhancing the efficiency in using the limited frequency resources. CONSTITUTION: When an available frequency bandwidth of systems in a first frequency bandwidth is searched, a CM(Coexistence Manager)(120,130) manages a plurality of systems for coexistence and frequency sharing. A CE(Coexistence Enabler)(150,170) transceives information of the systems and the CM. A CDIS(Coexistence Discovery and Information Server)(110) supports the control of the CM for the systems.
Abstract:
PURPOSE: A frequency allocating method for a frequency sharing system is provided to recognize available channel information in a frequency sharing system or a frequency allocation device by classifying each sub frequency resource. CONSTITUTION: If available sub frequency resources do not exist, an apparatus determines the existence of conditional available sub frequency resources(520, 530). If the conditional available sub frequency resource exists, the apparatus decides whether the regulation is satisfied(540). If so, the apparatus allocates conditional available sub frequency resources to a frequency sharing system(541). The apparatus determines the existence of the allocated sub frequency resource using RAT(Radio Access Technology)(550).
