Method for monitoring a communication system
First Claim
1. A method of monitoring operational performance of a mobile telephone unit in operation within a communications system involving a plurality of control stations by detecting signals passing between the mobile telephone unit and a particular control station during such operation, the method including the steps of establishing an identity of the mobile telephone unit from said detected signals and utilizing predetermined operational parameters of the detected signals as a source of information for monitoring operational performance of the communications system to identify a faulty mobile telephone unit automatically during normal operation of the mobile telephone unit and control station.

Abstract
A method is provided for monitoring operational performance of a communication system including a mobile telephone unit and a plurality of control stations, while the mobile telephone unit is in operation within the communication system. The method makes use of signals passing between the mobile telephone unit and one of the plurality of control stations during such operation. The method including the steps of establishing an identity of the mobile telephone unit from said signals and utilizing predetermined operational characteristics of the signals as a source of information for monitoring operation of the mobile telephone unit. Therefore, the method can detect automatically a faulty mobile telephone unit or control station during operation of the mobile telephone unit.

7. A method of automatically monitoring operational performance of a mobile telephone unit while the mobile telephone unit is in operation within a communications system including a plurality of base stations, the method comprising the steps of:
-
detecting a first signal transmitted by the mobile telephone unit to a particular base station; determining an identification number of the mobile telephone unit from the first signal; detecting a second signal transmitted by the mobile telephone unit to the particular base station during normal operation of the mobile telephone unit; decoding the second signal to determine an actual operational parameter of the second signal from the mobile telephone unit; and monitoring the actual operational parameter of the second signal to identify a faulty mobile telephone unit during normal operation of the mobile telephone unit. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of automatically monitoring operational performance of a mobile telephone unit while the mobile telephone unit is in operation within a communications system including a plurality of base stations, the method comprising the steps of:
-
detecting a signal from the base station, determining an identification number of the mobile unit from the signal detected from the base station, determining an allocated channel for the mobile telephone unit from the base station signal, detecting a signal transmitted by the mobile telephone unit to the base station on the allocated channel during normal operation of the mobile telephone unit, decoding the signal from the mobile telephone unit to determine an actual operational parameter of the signal from the mobile telephone unit, and monitoring the actual operational parameter of the signal to identify a faulty mobile telephone unit during normal operation of the mobile telephone unit.
