Inter-SAS spectrum allocation synchronization

A method for a first spectrum allocation system (SAS), the method comprising the first SAS:

• controlling existing first spectrum allocations to first base stations associated with the first SAS;
• accessing a spectrum-allocation database from a non-SAS spectrum-database server to retrieve information in the spectrum-allocation database about one or more existing second spectrum allocations to second base stations associated with a second SAS different from the first SAS, wherein (i) the non-SAS spectrum-database server is separate from the first SAS and the second SAS and (ii) the first and second SASs are operated by two different companies;
• and
• using the retrieved information to control new spectrum allocations to one or more of the first base stations associated with the first SAS, wherein the information comprises a geographical location of a second base station associated with an existing second spectrum allocation, an amount of spectrum allocated, a time of grant of the existing second spectrum allocation, a time of continued use of the existing second spectrum allocation, and a time of spectrum deallocation.

A first domain proxy comprising a proxy processor and proxy communication hardware, wherein the proxy processor is configured to control the first domain proxy to:

• receive, via the proxy communication hardware, a SAS-to-base station message from a first SAS and transmit the SAS-to-base station message to one of first base stations associated with the first SAS, wherein the SAS-to-base station message includes a first spectrum-allocation-related message related to an existing first spectrum allocation to the first base station associated with the first SAS;
• detect receipt of the first spectrum-allocation-related message;
• and
• transmit, via the proxy communication hardware, information related to the existing first spectrum allocation to a spectrum-database server that is separate from the first SAS, wherein, for the existing first spectrum allocation, the first domain proxy is adapted to transmit to the spectrum-database server information that identifies a geographical location of the first base station associated with the existing first spectrum allocation, an amount of spectrum allocated, a time of grant of the existing first spectrum allocation, and, if available, a time of continued use of the existing first spectrum allocation and a time of spectrum deallocation.
