Abstract

PURPOSE:To accurately perform the fault processing by depressing a service abnormality switch to temporarily hold the connection control data conducted just before and referring to this data. CONSTITUTION:If service abnormality is discriminated during communication and a service abnormality switch 4 is depressed, a control circuit 8 temporarily stores call processing data related data related to the abnormal communication call in a memory circuit 6. When normal communication is possible, a fault information transmission circuit 7 automatically transmits a signal to a data base device 19 of a centralized operation maintenance center 20 and reads out related data from the circuit and transmits it through a radio transmitter-receiver 9. This data are received by a radio transmitter-receiver 12 in a base station 2 and is transmitted from a radio base station control circuit 13 to a data reception circuit 14 of an exchange 3 for moving body communication. A central processing unit 16 reads related data from the circuit 14 and transmits it from a data transmission circuit 15 to a data reception circuit 17. An index number 18 is added to this data, and it is recorded in the device 19, and fault trace analysis, statistical processing of fault contents, etc., are performed based on this data.
