Patent ID: 8838798

Claim:
A system for managing resources in a communication system including a plurality of systems not having permission for a first frequency band, comprising: a memory; a processor coupled to the memory configured to execute programmed instructions stored in the memory comprising: a coexistence manager managing the plurality of systems for coexistence and frequency sharing of the plurality of systems in available frequency bands when the available frequency bands by the plurality of systems are searched in the first frequency band; a coexistence enabler transmitting and receiving information of the plurality of systems and information of the coexistence manager, wherein the information of the plurality of systems includes wireless access type, transmission power, spectral sensing threshold value, and position; and a coexistence discovery and information server (CDIS) supporting a control of the coexistence manager for the plurality of systems, wherein the coexistence manager is present in plural corresponding to each of the plurality of systems, and a first coexistence manager in the plurality of coexistence managers identifies the available frequency bands to allocate an operating channel of the plurality of systems based on channel information of the available frequency bands and channel information of neighbor coexistence managers, wherein the first coexistence manager allocates the operating channel by classifying the available frequency bands of the neighbor coexistence managers in classes including individual TV channel allocation type, shared TV channel allocation by television band device (TVBD) of same wireless access type, and shared TV channel allocation by TVBD of dissimilar wireless access type, and wherein the first coexistence manager receives the channel information of neighbor coexistence managers in response to at least one request by the first coexistence managers to the neighbor coexistence managers for the channel information of the neighbor coexistence managers, including TVBD Information of each TVBD registered in each respective neighbor coexistence manager, and wherein allocation of systems to classes, including the individual type, the shared same type, and the shared dissimilar type Is based upon providing efficient coexistence of the systems among the available frequency bands.
