<p>The present invention discloses a method for monitoring A interface circuit in wireless communication system, in each TRAU unit it set an persistent unactivated state timer of TRAU unit, for which an operation and maintenance unit of Base Station Controller (BSC) set a threshold value; simultaneously, set said timer to remain in nontiming state when the TRAU unit performs regular service, to start timing when the TRAU unit is set in nonservice state, and to remain in timing state during the TRAU unit is in nonservice state; when for said timer current timing value is equal to the threshold value being set, the TRAU unit reports the timeout information for locating the problems occurring in A interface circuit. Thus, abnormality that causes A interface circuit unusable, and break of upstream landline transmission from the BSC to the TRAU unit for various reasons, can be identified in time, to avoid wasting A interface circuit resources, to increase access success ratio in busy period, and to improve service quality and maintainability for Base Station Subsystem and even wireless communication network.</p> |
