【発明の名称】ディジタル式移動無線周波数監視
Document Type and Number:
Japanese Patent JP3073015
Kind Code:
B2
Abstract:
The frequency stability of the signals transmitted by a plurality of mobile stations to an associated base station within a radio network is supervised by first generating a reference signal at the base station. The signals received from the mobile stations are compared to the reference signal and a difference signal is generated. The difference signal is compared to first and second error values and if the difference exceeds the first error value, the mobile is summoned for a service adjustment. If the difference exceeds the second error value, the mobile is disabled from further transmissions.
