Patent ID: 8737207

Claim:
A system for managing resources in a communication system including a plurality of systems which do not have a permission for a first frequency band, the system comprising: a coexistence manager configured to, when a frequency band available for the plurality of systems is searched from the first frequency band, manage the plurality of systems for coexistence and frequency sharing of the plurality of systems in the available frequency band; a coexistence enabler configured to transmit and receive information of the plurality of systems and information of the coexistence manager; and a coexistence discovery and information server configured to support control of the coexistence manager over the plurality of systems, wherein a plurality of coexistence managers are provided to respectively correspond to the plurality of systems, and wherein the coexistence managers transmit and receive predetermined messages to and from the coexistence discovery and information server and the coexistence enabler, perform channel classification for the first frequency band, and determine operating channels of the plurality of systems on the basis of the channel classification.
