Abstract

PURPOSE:To detect a fault of a radio base station externally and to attain the setting of a communication line and the initial setting of the system at an exchange by providing a fault detector of the radio base station to a radio line controller in a mobile communication network where the ratio base station and the ratio line controller are connected by the exchange. CONSTITUTION:When a fault affecting the entire ratio base station (MBS) 1 takes place, a fault detector in the station 1 cannot detect the fault. Then a ratio base station fault detector 7 in a radio line controller 5 is used to always observe the transmission reception of the information between the MBS 1 and an exchange (AMS) 9. If any abnormity is recognized, fault information is sent and the said information is received by a fault information receiver 6 and reaches a line initial setting device 10 of the AMS 9. The device 10 identifies all communication lines 11 of the MBS 1 with the fault occurred therein, the charging processing is stopped to the communication line 11 in use and applies the initial setting.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

A wireless base station (hereinafter referred to as MBS) 1 that communicates with a mobile terminal has a failure detection device 2 that detects when a part of the base station function has failed, and a failure information device that sends out the failure information. It has a sending device 3.

The radio line control unit (hereinafter referred to as MCU) 5 is an MBSI
It monitors the operation of the fault information transmitting/receiving device 6 and MBSI, which have the function of relaying the fault information sent from the MBSI and the control information sent from the switching device 9, respectively, and detects faults separately from the fault information from the fault detection device 2. The wireless base station failure detection device 7 has a function of transmitting failure information. The switching device (hereinafter referred to as AMS) 9 has a function of identifying all call lines 11 accommodated in the AMS 9 and determining whether or not they are in use. The system has a line initial setting device 10 which has a function of once receiving fault information on a call line 11 in which a call is being made for the MBSI associated with the fault information and initializing it again. Between MBSI and MCU3, MBS-MCU

Connect via MCU-AMS control line 8. The maintainer 12 is
Maintenance work is being performed on AMS9.

FIG. 2 is a signal sequence diagram of one embodiment of the present invention.

Next, the operation will be explained.

Now, failures that occur in MBSI can be roughly classified into cases where the failure is a partial failure that is limited to a part, and cases where the failure is a total failure that affects the entire MBSI.

Normally, if the fault is a partial fault, the fault detection device 2 in the MBSI detects the fault and sends an MBS fault notification signal (
(hereinafter referred to as MTBL signal) from the failure information sending device 3 to M
It is sent to the fault information transmitting/receiving device 6 via the BS-MCU control line 4, and further reaches the line initial setting device 10 of the AMS 9 via the MCU-AMS control line 8. MT
When the line initial setting device 10 that has received the BL signal learns of the MBSI in which the failure has occurred, it further identifies all the call lines 11 accommodated in that MBSI and determines whether each call line is in use or not. . Next, open call line 11
No particular action will be taken for the call line 1 that is in use.
1, the billing process is first stopped, and then the telephone line 11 is initialized. At the same time, AMS9 maintainer 12
At the same time, the MBS failure notification confirmation signal (hereinafter referred to as MTBLA signal) is sent back to the MBSI.

In addition, if it is a general failure that affects the entire MBSI, either the failure detection device 2 in the MBSI where the failure has occurred is unable to detect the failure, or even if the failure can be detected, the MTB
Unable to detect L signal. Therefore, we used the radio base station failure detection equipment 7 in MCUS to detect MBSI and AMS.
The transmission and reception of information to and from 9 will be constantly observed. If an abnormality is detected in the transmission and reception of the SOP information, it is determined that a failure has occurred and the failure information is sent. After the fault information is received by the fault information transmitting/receiving device 6, it is sent to the MCU-AM as an MTBL signal.
Line initial setting device 1 of AMS9 via S control line 8
Let it reach 0. When the line initial setting device 10 that has received the MTBL signal learns of the MBSI in which the failure has occurred, as in the case of the above-mentioned partial failure, it further identifies all the call lines 11 accommodated in that MBSI and determines whether they are in use. For the telephone line 11, charging processing is first stopped, and then the telephone line 11 is initialized. At the same time, AMS9 maintainer 12 is notified of the MBS failure, and MTBL
Returns the A signal. This MTBLA signal is in this case M
It is not sent back to BSI and stops at MCU3.

When the faulty MBSI is restored normally, when the fault detection device 2 of the MBSI determines that the device is normal, the fault information sending device 3 sends a normal recovery signal (hereinafter referred to as MRT).
signal) is sent to the fault information transmitting/receiving device 6 via the MBS-MCU control line 4, which further transmits the signal to the MCU-A.
It reaches the line initial setting device 10 of the AMS 9 via the MS control line 8, and notifies the maintenance person 12 of the AMS 9 that the MBSI has been restored normally.
