System for managing frequency resources in multiple radio access networks and method thereof
First Claim
1. A system for managing frequency resources in a communication environment including multiple radio access networks employing various radio access schemes, the system comprising:
- a spectrum relay apparatus, wherein the spectrum relay apparatus calculates each frequency bandwidth to be allocated to the networks in consideration of priorities of the networks and priorities of service classes of each network, when a sum of frequency bandwidths requested from spectrum managers managing frequency resources for the networks is larger than an entire remaining bandwidth of the spectrum relay apparatus, and reports results of the calculation to corresponding spectrum managers;
conducts negotiation among the spectrum managers for a portion of the entire remaining bandwidth when the spectrum managers request an auction for frequency bandwidth allocation in response to results of the calculation, and allocates the entire remaining bandwidth to the spectrum managers according to a result of the negotiation;
makes a portion of the entire remaining bandwidth available for auction to the spectrum managers when the negotiation does not result in an agreement, and allocates the entire remaining bandwidth to the spectrum managers according to a result of the auction; and
allocates the frequency bandwidth to the spectrum managers according to the result of the calculation when no spectrum manager requests the auction in response to the result of the calculation.

Abstract
Disclosed is a system and method for managing frequency resources, that is, a system and method for dynamically allocating and managing frequency resources in multiple radio access networks (RAN). In multiple radio access networks, the system and method manages frequency resources in consideration of the priorities of radio access networks and the priorities of service classes of each radio access network, and manages the frequency resources through negotiation and auction for frequency resources among the radio access networks.
