Inquiring of a protected communications services database to address concerns over blind base station operation in conflict with protected communications services

A method for a base station to establish a service network providing a non-protected wireless bi-directional telecommunication service operable on a plurality of frequencies, comprising:

• inquiring by the base station of a protected services database to retrieve stored information concerning the existence and operation of at least one protected wireless unidirectional broadcast service operating on a reserved one of said plurality of frequencies in a given geographic area;
• evaluating the retrieved information;
• selecting frequencies from the plurality of frequencies based on the evaluation which would not interfere with the frequency reserved in the given geographic area for use by the at least one protected wireless unidirectional broadcast service;
• and
• establishing the non-protected wireless bi-directional telecommunication service using the selected frequencies.

A system configured to provide a non-protected wireless bi-directional telecommunication service operable on a working channel that is reserved for use by at least one protected wireless unidirectional broadcast service, comprising:

• a base station configured for operation, prior to establishing the non-protected wireless bi-directional telecommunication service, to:
• inquire of a protected service database for the identification of protected wireless unidirectional broadcast services which could potentially be adversely affected by base station establishment of the non-protected wireless bi-directional telecommunication service on said working channel,
• evaluate a received database response to the inquiry, and
• determine at least one available working channel for the non-protected wireless bi-directional telecommunication service which would not interfere with the identified protected wireless unidirectional broadcast services.
