How to get this document?

Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller and radio resource manager. A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager, which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.
