Channel allocation in protected service areas

A machine-readable, non-transitory, storage medium, having encoded thereon program code, wherein, when the program code is executed by a machine, the machine implements a method of allocating operating channels by a remote device, the remote device within a geographic area having a plurality of protected classes of service, comprising:

• determining a location of the remote device;
• transmitting to a server a query message having a device identification, at least one query location, and one or more desired channels of operation corresponding to each query location based on the location of the remote device;
• and
• receiving a channel list from the server,
• wherein the server forms the channel list for each query location by:
• (i) retrieving pre-computed nested, classified tiles of successive levels of resolution, each tile classified as to channel availability based on verification of protection requirements for protected service contours corresponding with one or more protected classes of service;
• (ii) identifying, beginning with a first level and searching successive levels of the nested, classified tiles of successive levels of resolution, a classified tile classified as available with the query location based on the one or more desired channels of operation;
• and
• (iii) allocating channels, if available, associated with the identified, classified tile with the query location to the channel list.

Apparatus for allocating communication channels by a remote device, the remote device within a geographic area having a plurality of protected classes of service, comprising:

• a location module configured to determine a location of the remote device;
• a processor of the remote device configured to form a query message having a device identification, at least one query location, and one or more desired channels of operation corresponding each query location based on the location of the remote device;
• and
• a wireless module of the remote device configured to transmit the query message to a server;
• and
• receiving, by the processor, a channel list from the server,
• wherein the server forms the channel list for each query location by:
• (i) retrieving pre-computed nested, classified tiles of successive levels of resolution, each tile classified as to channel availability based on verification of protection requirements for protected service contours of the plurality of protected classes of service;
• (ii) identifying, beginning with a first level and searching successive levels of the nested, classified tiles of successive levels of resolution, a classified tile classified as available with the query location based on the one or more desired channels of operation;
• and
• (iii) allocating channels, if available, associated with the identified, classified tile with the query location to the channel list.

A remote device in communication with a channel allocation system, the remote device operating within a geographic area having one or more protected classes of service, the remote device comprising:

• a location module configured to determine a location of the remote device;
• a processor configured to form a query message having a device identification, at least one query location, and one or more desired channels of operation corresponding to each query location based on the location of the remote device;
• and
• a communication interface configured to transmit the query message to the channel allocation system and to receive a channel list from the channel allocation system,
• wherein the channel allocation system forms the channel list for each query location by:
• (i) retrieving pre-computed nested, classified tiles of successive levels of resolution, each tile classified as to channel availability based on verification of protection requirements for protected service contours corresponding with one or more protected classes of service;
• (ii) identifying, beginning with a first level and searching successive levels of the nested, classified tiles of successive levels of resolution, a classified tile classified as available with the query location based on the one or more desired channels of operation;
• and
• (iii) allocating channels, if available, associated with the identified, classified tile with the query location to the channel list.
