Malfunction detection method and base station apparatus utilizing the same
First Claim
1. A base station apparatus, comprising:
- a control unit which allocates a predetermined channel to a terminal apparatus to be communicated and allocates another channel, which differs from said channel allocated to the terminal apparatus, to a control signal;
a communication unit which communicates with the terminal apparatus to which the predetermined channel is allocated to and which transmits periodically said control signal to which a channel other than said channel is allocated;
a measuring unit which receives periodically, via said communication unit, a control signal from another base station apparatus through the channel other than the channels allocated to the terminal apparatus and the control signal, and which measures the quality of the thus received control signal; and
a detection unit which detects a malfunction, if any, of the communication unit based only on the quality of the control signal measured by said measuring unit.

Abstract
A measuring unit inputs a detection received signal and measures a received RSSI value as the detection received signal. A first comparator inputs a plurality of received RSSI values measured by the measuring unit and compares them with a predetermined threshold value. A signal difference deriving unit derives a relative relationship among the plurality of RSSI values. A second comparator compares the relative relationship with a predetermined value. If the first comparator and the second comparator detect any malfunction, a decision unit receives notification accordingly from the first comparator and the second comparator and finally judges the malfunction of communication functions associated therewith.

15. A malfunction detecting method characterized in that a control signal is received periodically from another base station apparatus by a predetermined channel allocated to a terminal apparatus to be communicated and another channel, which differs from the channel allocated to the terminal apparatus, the another channel differing from the channel allocated to the control signal, the quality of the received control signal is measured, and a malfunction of functions to communicate with the terminal apparatus is detected based on the measured quality of control signal.
