Abstract:
A method for detecting a failure mobile station forming a wireless communication network together with at least one base station, comprising:a) determining the electric power of a first signal supplied from said failure mobile station to said at least one base station by said at least one base station;b) supplying a transmission power control instruction from said at least one base station to said mobile station;c) changing the electric power of a second signal to be supplied from said mobile station to said at least one base station by said failure mobile station in response to said transmission power control instruction;d) determining the electric power of said second signal supplied from said mobile station to said at least one base station by said at least one base station;e) comparing said electric power of said second signal with said electric power of said first signal to see whether or not a relative relation therebetween is consistent with said transmission power control instruction by said at least one base station; andf) diagnosing said mobile station as a failure station by said at least one base station when said relative relation is inconsistent with said transmission power control instruction.
