JPH104381A - Automatic block system for radio transmitter-receiver - Google Patents

Abstract

PROBLEM TO BE SOLVED: To allow all of a plurality of radio transmitter-receiver sets connecting to a faulty radio transmission amplifier on the occurrence of a fault to be automatically blocked so as not to cause assignment of a call to a plurality of the radio transmitter-receiver sets connecting to the faulty radio transmission amplifier on the occurrence of a fault. SOLUTION: When a combination among radio transmitter-receiver sets 17 to 22 and radio transmission amplifiers 9, 11, 13 amplifying signals from the radio transmitter-receiver sets 17 to 22 is n (n is an integer 2 or over):1, the combinations are stored. Thus, on the occurrence of a fault in any of the radio transmission amplifiers 9, 11, 13, all of the radio transmitter-receiver sets in combination with a faulty radio transmission amplifier are blocked based on the stored combinations.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for automatically closing a radio transceiver, and more particularly to a system for automatically closing a radio transceiver affected by a failure of a radio transmission amplifier in a radio base station apparatus in a mobile communication system.

[0002]

2. Description of the Related Art A conventional automatic closing system is disclosed in
As disclosed in Japanese Patent Application Laid-Open No. 1-50453, in a device having a one-to-one relationship, a confirmation signal is periodically transmitted from one device to another device, and the response to the confirmation signal is interrupted. In some cases, one configuration (a line in Japanese Patent Application Laid-Open No. 61-50453) connected to a device that has stopped responding is closed.

[0003] A radio transceiver (hereinafter referred to as "T") in a radio base station apparatus (hereinafter referred to as "BTS") in a mobile communication system.
RX)) and a wireless transmission amplifier for amplifying a wireless signal (hereinafter referred to as “TXAMP”), the TRX and the TXAMP have conventionally corresponded one-to-one. Therefore, when a failure occurs in TXAMP,
Cell site controller (hereinafter “CSC”)
Is the TRX corresponding to the failed TXAMP
Was closed to prevent call assignments.

[0004]

However, recently,
The relationship between TRX and TXAMP is not one-to-one, but an n-to-one configuration in which a plurality (n) of TRXs are connected to one TXAMP is being studied.
The combination of X and TXAMP can be changed in various ways. In such a case, the device that sends the confirmation signal is CSC, and the device to be confirmed is BSC.
The devices that are TXAMPs in the TS and are closed when the confirmation signal is interrupted are a plurality of TRXs connected to the TXAMP. However, since CSC does not manage the combination of TRX and TXAMP, even if a failure occurs in TXAMP and the response to the confirmation signal is interrupted,
It is not known whether or not to perform the blocking control on the TRX. Therefore, there is a problem that a call is assigned to an unusable TRX. Thus, the failed TXAM
If a call is assigned to the TRX connected to the P, the TXAMP will be mistaken for the completion of the transmission even though the transmission has not been performed correctly due to the failure of the TXAMP. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has been made in the event of a failure in a radio transmission amplifier so that calls cannot be assigned to a plurality of radio transceivers connected to the radio transmission amplifier in which the failure has occurred. An object of the present invention is to provide an automatic closing system for a wireless transceiver in which all of a plurality of wireless transceivers connected to an amplifier are automatically closed.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an automatic blocking system for a radio transceiver in a radio base station apparatus in a mobile communication system. When the combination with the wireless transmission amplifier for amplifying the signal is n (where n is an integer of 2 or more) to 1, this combination is stored, so that when a failure occurs in the wireless transmission amplifier, Based on the stored combination, all of the wireless transceivers combined with the failed wireless transmission amplifier are closed.

[0007] The central control and monitoring device in the radio base station device constantly monitors the status of the radio transceiver and the radio transmission amplifier. In the present invention, the central control and monitoring device also manages the combination of the wireless transceiver and the wireless transmission amplifier, and utilizes the fact that the cell site controller performs blocking control on the wireless transceiver that has reported the error. In the event that a failure occurs in the wireless transmission amplifier, the radio base station apparatus voluntarily reports errors of all the related radio transceivers, and shuts down the radio transceiver by prompting the cell site controller to shut down, This is to prevent a new call from being assigned.
