DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system in which a control station device for controlling a base station and a plurality of base station devices are connected via a general network, and the base station device is remotely operated from the control station device. The present invention relates to a method for performing a reset.

[0002]

2. Description of the Related Art In a communication system in which a control station device and a plurality of base station devices are connected via a general network, there is a case where the control station device wants to reset an arbitrary base station device for maintenance or the like.

[0003] This type of base station reset method includes a technique described in Japanese Patent Application Laid-Open No. 5-37448.

First, in a first method, in a communication system in which a control station device for controlling a base station and a plurality of base station devices are connected by a line, reset information is transmitted from a communication signal processing unit of the control station device. The signal including the reset information is transmitted to the base station device to be reset via a line, and the signal including the reset information is transmitted to the base station device by a communication signal processing unit which largely depends on software processing. The reset information is recognized by receiving and decoding. After the recognition, the inside of the own base station device is reset according to a predetermined procedure.

In a second method, in a communication system in which a control station device and a plurality of base station devices are connected by a dedicated line, the control station device controls the electrical physical state of each base station line on / off. The base station is provided with detection means for detecting the on / off state of its own line, and the control station device turns off the line connected to the base station to be reset, and The base station was reset by detecting this.

[0006]

In the above-described first conventional base station reset method, the communication signal processing section of the base station device which has received the signal including the reset information transmitted by the control station device has the above configuration. If the signal cannot be decoded by software processing, or if the signal falls into a state that cannot be decoded by software processing, resetting is not performed and remote operation becomes impossible. In addition, there is a possibility that an erroneous operation may affect the entire system. The reason is that the communication signal processing unit of the base station device decodes the signal.

In the second conventional base station reset method, the control station apparatus and a plurality of base station apparatuses use a dedicated line to turn on / off the electrical physical state of the line. Therefore, when a new base station is installed, a dedicated line is required, which increases the cost. In addition, if a conventional line network is used, this method cannot be realized, and the effectiveness of this method is limited. In the case of the daisy chain system in which a plurality of base stations are connected to one dedicated line, there is a disadvantage that all the base station devices connected to the line are reset.

[0008] It is an object of the present invention to provide a base station reset method capable of reliably performing resetting, reducing malfunctions of a base station apparatus by remote control, and improving maintenance efficiency.

It is another object of the present invention to provide a base station reset system which can use a conventional line without being restricted by a line when installing a base station apparatus.

Still another object of the present invention is to make it possible to reset only a base station device to be reset even in a daisy chain system in which a plurality of base station devices are connected to one line. To provide a base station reset method.

SUMMARY OF THE INVENTION In a communication system in which a control station device for controlling a base station and a plurality of base station devices are connected via a general line network, the control station device communicates with the general line network. And a communication signal processing unit for decoding and transmitting information in the line. The base station apparatus includes a line control unit for communicating with a general line network, A communication signal processing unit that decodes and sends information at a timing assigned to the own base station, and a reset pattern detection unit that detects reset pattern information including reset pattern information by a hardware decoding circuit. doing.

According to the present invention, since the reset pattern information including the information of the reset pattern is decoded by hardware, it is not necessary to decode the signal, and only the base station device to be reset can be reliably reset. It is possible. In addition, since communication is performed using a general network, a dedicated line is not required.

The base station device includes an ATM control unit 6 for communicating with an ATM line network, a reset pattern detection unit 7 for detecting information including reset pattern information by a hardware decoding circuit, A communication signal processing unit 8 for decoding and transmitting information at a timing assigned to the base station from the ATM line.

In order for the communication signal processing unit 10 of the control station apparatus 4 to send signals to the base station apparatuses 1, 2, and 3, respectively, as shown in FIG. 2, each base station in the header of an ATM cell (Cell) , And sends the signal to the ATM network 5 via the ATM line 11.

In the ATM network 5, the V of the header of the transmitted cell is
Decode the PI and VCI to obtain the respective base station devices 1,
The call is distributed to ATM lines 12, 13, and 14 connected to 2,3.

In the base station devices 1, 2, 3 the ATM
The control unit 6 determines whether the cell is addressed to the own base station device by VPI, V
Judging by looking at the CI, if it is addressed to the own base station apparatus, it is transmitted to the reset pattern detecting section 7 and the communication signal processing section 8.

The above is a description of general information transmission. Next, an operation when a specific base station apparatus is reset from a control station apparatus will be described.

Now, it is assumed that the base station device 1 is reset. In this case, the communication signal processing unit 10 of the control station device 4, as shown in FIG.
The reset pattern information is put in the header of the cell to which the CI is assigned, and sent to the ATM line 11.

In the ATM network 5, the V of the header of the transmitted cell is
The PI and VCI are decoded and distributed to the ATM line 12 connected to the base station device 1.

In the base station device 1, the ATM control unit 6
The VPI and VCI are used to determine whether the cell is addressed to the own base station apparatus, and if it is addressed to the own base station apparatus, the cell is transmitted to the reset pattern detecting unit 7 and the communication signal processing unit 8.

The reset pattern detecting section 7 decodes the reset pattern of the header of the ATM cell by hardware, and when a match is detected several times in succession, recognizes that a reset instruction has been received, generates a reset signal, and generates a reset signal. Reset the inside.

[0025]

According to the present invention, since the reset cell containing the information of the reset pattern is decoded by hardware, the circuit can be easily realized, and the communication signal processing greatly depends on the software processing. Since the reset is not related to the unit, the reset is reliably performed, and the malfunction of the base station device due to the remote control can be reduced, and the maintenance efficiency can be improved.

Further, according to the present invention, since the control station device and the base station device are not connected by a dedicated line, the installation of the base station device is not restricted by the line, and the conventional line is used. Because it is possible, the line usage fee is reduced. Further, even in the case of a daisy chain system in which a plurality of base station devices are connected to one line, it is possible to reset only the base station device to be reset. The reason is that communication is performed using standard cells on the ATM network, and a reset cell including reset pattern information can be transmitted to a base station device to be reset. is there.
