Patent ID: 8755830

Claim:
A central control system for supplying spectrum access information for use in wireless communications to radio devices that request spectrum access from the central control system, comprising: an interface to communicate with the radio devices; and a processor that executes a spectrum allocation function that is stored in a non-transitory computer readable medium and, by execution of the spectrum allocation function, the central control system configured to: receive a request from one of the radio devices, the request specifying a location of the radio device; determine spectrum that is available for use by the radio device at the location of the radio device and at the time of the request; determine when some of the available spectrum becomes protected from use by the radio device by commencement of a protected venue located at least in part in a time zone adjacent a time zone corresponding to the location of the radio device, the central control system normalizing a time at which the protection of the protected venue commences to a universal time; establish a re-request time duration specified as an amount of time that is less than an amount of time until the protection of the protected venue commences, elapsing of the re-request duration serving as a command to the radio device to transmit a new request to the central control system; and transmit an identification of the available spectrum and the re-request time duration to the radio device.
