Abstract

<P>PROBLEM TO BE SOLVED: To provide a relay base station apparatus for stopping transmission of a radio carrier when the relay base station apparatus falls into a state of disabling the normal operation due to abnormity in a wired transmission line so as to avoid confusion of the system operation caused by useless accesses of radio terminals thereby avoiding wasteful power consumption of the relay base station apparatus. <P>SOLUTION: A radio base station 1 for exchanging data with a host controller 3 connected to the radio base station 1 via a wired transmission line 2 is provided with: a means 15a for detecting the abnormity in the wired transmission line 2; and a means 16c for turning off the radio transmission power in response to the detected abnormity. The means 16c turns off the transmission power on the occurrence of the abnormity in the wired transmission line 2 to stop transmission of the radio carrier. Further, the means 16c turns off the transmission power after a timer 16b counts a time so as to avoid a time loss for operation restart when the abnormity of the wired transmission line is momentary. <P>COPYRIGHT: (C)2004,JPO

The base station device 1 wirelessly connects to a wireless terminal 4 in a wireless area. Then, between the backbone network N and the wireless terminal 4, the user data is stored in the wireless base station device 1, the wired transmission path 2,
It is transmitted via the wireless network control device 3. In the example shown in FIG. 1, a plurality of wireless base station apparatuses 1 are connected to one wireless network control apparatus 3 via a wired transmission path 2 and controlled. In such a system configuration, the wireless base station apparatus 1 mainly has functions related to wireless communication such as a wireless signal processing function and a wireless modulation / demodulation function, and the wireless network control apparatus 3 mainly has a wireless line control function. It has other functions necessary for communication such as a function, an exchange control function, an error control function, an interface function with the backbone network N, and the like, and the wireless base station device 1 and the wireless network control device 3 cooperate. Thereby, communication between the wireless terminal 4 and the backbone network N is realized. [0005] Here, in the relay base station apparatus 1 operating under the control of the control device 3 connected by the wired transmission path 2 as described above, an abnormality on the wired transmission path is considered. Occurs and hinders data exchange with the control device 3, the wireless connection service to the wireless terminal 4 cannot be performed normally. That is, the relay base station apparatus 1
Cannot receive the control data from the device, and the control becomes impossible. [0006] Even when the situation where normal operation cannot be performed due to an abnormality in the wired transmission path is depressed as described above, the relay base station apparatus 1 continues transmission of a wireless carrier, so that service cannot be performed. There is a problem that confusion in system operation that the wireless terminal 4 accesses the relay base station apparatus 1 occurs, and that the relay base station apparatus 1 itself consumes useless power. . [0007] The present invention has been made in view of the above-described conventional circumstances, and has as its object to provide a relay base station apparatus capable of rationally solving the above-mentioned problem with respect to an abnormality in a wired transmission line. . Further objects of the present invention will be apparent in the following description. According to the present invention, there is provided a relay base station apparatus for exchanging data with a control device connected via a wired transmission path, the apparatus comprising: And means for turning off the wireless transmission power in response to the abnormality detection. Therefore, when the relay base station apparatus falls into a state in which the relay base station apparatus cannot operate normally due to an abnormality in the wired transmission path, the transmission of the wireless carrier from the relay base station apparatus is stopped, so that the wireless terminal does not needlessly access. Can be avoided, and wasteful power consumption of the relay base station device can be avoided. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A relay base station apparatus according to the present invention will be specifically described based on embodiments. FIG. 1 shows a configuration of a CDMA radio base station apparatus according to an embodiment of the present invention, and FIG. 2 shows an example of a control processing procedure for occurrence of an abnormality in a wired transmission path. Since the system configuration shown in FIG. 3 is the same in the present example, the same reference is made to FIG. 3 as needed, and the same portions are denoted by the same reference numerals and redundant description is omitted. As shown in FIG. 1, a CDMA radio base station apparatus 1 includes an antenna 11, a transmission amplifier unit 12, and a radio unit 1.
3, a baseband signal processing unit 14, a wired transmission line interface unit 15, and a control unit 16. In FIG. 1, illustration of other wireless base station apparatuses is omitted. In the radio base station apparatus 1, user data from the backbone network is input from the wire transmission line interface unit 15 via the radio network control device 3 and the ATM wire transmission line 2, and the user data is subjected to baseband signal processing. The error correction coding, data modulation, and spread modulation are performed by the unit 14 and the D / D
The signal is converted into a radio frequency signal by A-conversion, further amplified by the transmission amplifier unit 12, and transmitted from the antenna 11 to the radio area. On the other hand, on the other hand, the data received from the antenna 11 is A / D-converted by the radio unit 13 and subjected to despreading, error correction decoding, data demultiplexing and the like by the baseband signal processing unit 14, and The signal is output from the transmission line interface unit 15 to the wireless network control device 3 via the wired transmission line 2. The transmission / reception processing as described above is executed under the control of each of the functional units 12 to 15 by the control unit 16, and the control unit 1
6 is provided with a system data storage unit (SDM) 16a composed of a non-volatile memory.
A control process is executed based on various parameters stored in M16a and control data received from the wireless network control device 3 via the wired transmission line 2 as needed. In addition, SDM
16a, various parameters are set and stored by local operation, or FTP (File Transfer Protocol) is used.
l) Wireless network controller 3 by file transfer
And received via the wired transmission path 2 and stored. The wire transmission line interface unit 15 of the present embodiment
Detects an abnormality (interruption of input data signal, abnormal operation of data signal exchange, etc.) occurring in the wired transmission line 2 in addition to a function of inputting / outputting user data and control data to / from the ATM wired transmission line 2 at high speed. It has an abnormality detection function 15a that performs Here, each of the functional units 12 to 15 including the control unit 16 may be configured by executing a predetermined program by a processor, and each function may be configured as dedicated hardware. In the example, the wired transmission line interface unit 15 is configured as dedicated hardware in the form of a card, and is mounted on the wireless base station device 1. Thereby, even when the normal operation cannot be performed due to the abnormality of the wired transmission line 2, the abnormality detection function 15a detects the occurrence of the abnormality, and the handling processing functions 16b to 16d of the control unit 16 necessary for the processing shown in FIG. Can be started. The control unit 16 includes, in addition to the control functions of the functional units 12 to 15, a timer 16b for measuring a predetermined time, a transmission amplifier unit 12, a radio unit 13, and a transmission process to be supplied to the baseband signal processing unit 14. A power control function 16c for turning on / off the power for the power supply, and a reset control function 16d for restarting the wireless base station device 1 itself.
The time measured by the timer 16b can be arbitrarily changed by parameters set and stored in the SDM 16a.
When the abnormality detection function 15a detects an abnormality in the wired transmission path 2, these functions 16b to 16d cooperate to execute a coping process shown in FIG. During operation of the wireless base station apparatus 1, the abnormality detecting function 15a constantly monitors the communication state of the wired transmission line 2 (step S1). The control unit 16 determines whether the failure is in the wireless base station device 1 itself (step S2). That is, when an error occurs in the hardware or software of the wireless base station device 1 itself and appears as a transmission error in the wired transmission path 2, the reset control function 16d resets the wireless base station device 1 itself ( Step S3). Instead of or together with the reset process, the power control function 16
The transmission power supply may be turned off (cut off) by c.
This makes it possible to avoid confusion due to useless access of the wireless terminal and to avoid wasting power consumption of the wireless base station apparatus. On the other hand, if there is no abnormality in the wireless base station device 1 itself, the timer 16b starts counting time (step S).
4) When the timer 16b finishes measuring the predetermined time (step S6), the power control function 16c turns off the supply of the transmission power (step S7), and the recovery of the wired transmission path 2 to the normal state is performed. It waits (step S8).
The normal recovery of the wired transmission line 2 is detected by the abnormality detection function 15a, the supply of the transmission power is restarted by the power control function 16c, and the control processing is restarted by re-reading the setting data of the SDM 16a. Here, even during the time counting process by the timer 16b, the abnormality detection function 15a monitors the state of the wired transmission line 2 (step S5), and confirms that the wired transmission line 2 has recovered to a normal state. Upon detection, the timer 16b stops the timekeeping process (step S9), and the functional units 11 to 15 cooperate under the control of the control unit 16 to restart the operation of the wireless base station device 1 (step S10). . That is, if the transmission power is cut off or the reset processing is performed, it takes some time to restart the operation of the wireless base station apparatus 1 such as rereading the system data. ), The operation can be resumed immediately if the abnormality of the wired transmission line 2 is instantaneous. Although the CDMA wireless base station apparatus has been described as an example, the present invention provides a PDC (Personal Dig).
