System and method to facilitate time management for protected areas

摘要

Spectrum that will become venue-protected in the future is made available to radio devices by a central control system with which the radio devices requests spectrum access information for use in wireless communication. The central control system establishes a re-request time duration specified in an amount of time that will elapsed at or before the spectrum becomes protected. The elapsing of the re-request duration serves as a command to the radio device to transmit a new channel request to the central control system.

主权项

1. 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; andtransmit an identification of the available spectrum and the re-request time duration to the radio device.
