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

摘要

A database stores updated information concerning protected communications services. A base station for a coexisting, and potentially co-channel, non-protected communications service makes an inquiry of the database requesting an identification of geographically relevant protected services along with the database stored information pertinent to each of those identified protected services. The returned information is processed by the base station to determine what channels are available for use by the non-protected service. An available channel is identified by the base station as the working channel for the non-protected service and the base station initiates a process to establish a communications network using the non-protected service and the selected working channel.
