Description

APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA OF A FULL ELECTRONIC SWITCHING SYSTEM

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic switching system, and more particularly, to an apparatus and method for transmitting and receiving data of an electronic switching system which reduces a load between internal processors of the electronic switching system in the process of transmitting and receiving data with an external remote system.

In connection with the present invention, Figure 3 is a block diagram of the electronic switchboard schematically showing the process of transmitting and receiving data with an external remote device in a conventional electronic switchboard, the file recording controller 311, the first hard An operating maintenance processor 310 composed of a disk 313, a first memory 315, and a remote matching processor 320 composed of a data communication device 321, a second memory 323, and a second hard disk 325. Include.

Referring to FIG. 3, when the electronic switch 300 transmits a large amount of data to the remote system 400, the file recording controller 311 in the operation maintenance processor 310 is connected to the first hard disk 313. The stored file is read in a packet unit of a predetermined size (for example, 7 Mbtye) and temporarily stored in the first memory 315, and then, again, the file name and file content of the temporarily stored data through IPC (Inter Processor Communication). Data) is transmitted to the remote matching processor 320 in a packet unit (for example, 280 bytes) of a predetermined size.

The data communication device 321 in the remote matching processor 320 writes the data received from the file recording controller 311 into the second memory 323. That is, the data communication device 321 receives data provided from the file recording controller 311 by a predetermined packet unit (280 bytes, which is an IPC transmission unit), and stores the data in the second memory 323. At this time, the data communication device 321 transmits to the file recording controller 311 a signal ack indicating that the data is received every packet unit.

In addition, data of a predetermined size preset in the second memory 323, for example, data of a predetermined recording unit size for recording on the second hard disk 325 or data corresponding to a capacity of the second memory 323 is stored. Once stored, the data is read again and recorded on the second hard disk 325.

When the data from the operation maintenance processor 310 is completed through the above process to the remote matching processor 320, the data communication device 321 in the remote matching processor 320 stores the data stored in the second hard disk 325. Read it back and send it to an external remote system (not shown) using a communication protocol such as TCP / IP or X.25. At this time, when the communication protocol with the external remote system matched through the network is X.25, the transmission unit becomes 128 bytes.

Meanwhile, referring to the process of the electronic switch 300 receiving data from an external remote system, the data communication device 321 in the remote matching processor 320 transmits data from an external remote system through a network. If received, data transmitted using a communication protocol such as TCP / IP or X.25 is received and recorded in the second memory 323. As in the above-described example, the received data stored in the second memory 323 is recorded in the second hard disk 325.

When all data received from the external remote system through this process are recorded on the second hard disk 325, the data communication device 321 manages the data recorded on the second hard disk 325. The file recording controller 311 is transferred to the file recording controller 311, and the file recording controller 311 records the data on the first hard disk 313, thereby ending the reception process for the data transmitted from the remote system.

On the other hand, in the data communication process between the conventional electronic switch 300 and the external remote system as described above, the IPC between the processors (310, 320) in the electronic switch 300 to increase the There is a problem that the load is increased. That is, in the process of transmitting and receiving data in the unit of packet between the processors 310 and 320, an acknowledgment message (ack) is generated every time a packet is transmitted and received, thereby increasing the load of the system due to the increase of IPC. .

In addition, a separate memory means for temporarily storing data is required in the process of transmitting and receiving data between the processors 310 and 320, and a hard disk for storing the received data is also separately provided, thereby reducing economic efficiency due to system implementation. There is a problem. In the data transmission / reception process, since each processor 310 or 320 rewrites data to each of the memories 315 and 323 and the second hard disk 325 and then transmits and receives data, a transmission delay occurs as much as that. There is a problem that cannot be transmitted in real time.

The present invention has been made to solve the above problems, the data transmission and reception apparatus of the electronic switchboard which can reliably transmit and receive data by reducing the load on the system in the process of transmitting and receiving data with an external remote system in the electronic switchboard. And to provide a method.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

1 is a block diagram showing the configuration of a data transmission and reception apparatus of an electronic switch 100 according to a preferred embodiment of the present invention, the file recording controller 111, hard disk 113, IPC controller 115 And a remote matching processor 120 composed of a configured operational maintenance processor 110, a data communication controller 121, a data communication processor 123, and a memory 125.

Referring to FIG. 1, first, in the case of transmitting data from the electronic switch 100 to an external remote system 300, the file recording controller 113 in the operation maintenance processor 110 may include the hard disk 113. If there is an untransmitted file (data), the file name for the file is transmitted to the data communication controller 121 in the remote matching processor 120, and the data communication controller 121 in the remote matching processor 120 transmits the file. The file name transmitted from the recording controller 111 is transmitted to the data communication processor 123.

The data communication processor 123 in the remote matching processor 120 transmits data corresponding to the file name transmitted from the IPC controller 115 from the hard disk 113 by IPC transmission amount (280 bytes) by the IPC controller 115. Read and convert to TCP / IP or X.25 protocol to external remote system (not shown).

In this case, the memory 125 performs a function of buffering the data transmitted from the operation maintenance processor 110. In detail, the memory 125 is used to transmit data from the electronic switchgear 100 to an external remote system. When the communication protocol is X.25, the transmission unit becomes 128 bytes, which is different from the IPC transmission amount, that is, 280 bytes in the unit for transmitting data from the operation maintenance processor 110 to the remote matching processor 120. do. Accordingly, the memory 125 temporarily stores data at the time of transmission delay and performs buffering.

On the contrary, when the electronic switch 100 receives a data transmitted from an external remote system (not shown), the external remote system may first check file information (file name and loading information) regarding data to be transmitted. Information) is transmitted to the data communication controller 121 through the data communication processor 123 in the remote matching processor 120, and the data communication controller 121 stores the received file information (file name and loading information). It transfers to the file recording controller 111 in 110.

When the contents (data) of the corresponding file are received from the external remote system through the network to the data communication processor 123 in the remote matching processor 120, the data communication processor 123 stores the received data in the operation maintenance processor ( The hard disk 113 is recorded through the IPC controller 115 in the 110. At this time, the IPC controller 115 reads the contents of the file recorded on the hard disk 113 in the operation maintenance processor 110 of the electronic switchboard 100 or records the data received from the outside.

2A and 2B are flowcharts illustrating a data transmission / reception process of an electronic switching system according to a preferred embodiment of the present invention. A series of processes described above with reference to the accompanying drawings will be described below.

First, referring to FIG. 2A, a process of transmitting data from the electronic switch 100 to a remote system, not shown, is described. Referring to FIG. 1, the electronic switch 100 including each component as shown in FIG. With the overall operation in stand-by mode for transmitting and receiving data to and from a matched external remote system over the network (step 201), the file recording controller 111 reads the hard disk 113 to omit the illustration. It is checked whether data to be transmitted to the remote system is present in the hard disk 113 (step 203).

As a result of the check, if there is data to be transmitted, the file recording controller 111 reads the file name of the data to be transmitted and transmits it to the data communication controller 121 (step 205), and the data communication controller 121 again returns the data. The file name is transmitted to the communication processor 123 (step 207), where the data communication controller 121 also transmits a file transfer request message for the file.

In response to the file transfer request message, the data communication processor 123 reads out the corresponding data recorded in the hard disk 113 through the IPC controller 115, that is, the data corresponding to the file name (step 209), and then TCP / IP or X .25 send to a remote system not shown using a communication protocol (step 211).

Through this process, the data exchanged on the hard disk 113 is transferred from the electronic switch 100 to a matched remote system through a network. When the transmission is completed (step 213), the data communication processor 213 generates a data transmission process completion message and notifies the IPC controller 115, thereby ending the overall processing according to the data transmission (step 215).

On the other hand, a process of receiving and recording data from an external remote system in the electronic switchgear 100 will be described with reference to FIG. 2B. The standby state of the electronic switchboard 100 shown in FIG. When the data transmitted from the remote system (step 251) and the corresponding file information (file name, whether the file is loaded, etc.) are received by the data communication processor 123 in the remote matching processor 120 (step-by) (step 251) (step 251). 253), the data communication processor 123 transmits the received file information (file name, loading information) to the file recording controller 111 of the operation maintenance processor 110 through the data communication controller 121 (step 257). .

Subsequently, the data communication controller 123 records data received from an external remote system on the hard disk 113 in the unit of IPC transmission amount (280 bytes) through the IPC controller 115.

When the reception and recording of data transmitted from the remote system is completed through this process (step 263), the data communication processor 123 generates a data reception completion message and notifies the IPC controller 115 (step 265). At this time, the file recording controller 111 determines whether or not to load the data received from the file information transmitted in the above-described step (257) (step 267), if the determination result, the received data is the data to be loaded In this case, the system operates by loading the data recorded on the hard disk 113 (step 269).

As described above, according to the present invention, by providing a separate path for controlling the IPC between each processor and the actual data transmission and reception in the electronic switchboard to reduce the load on the system, it is possible to improve the stability of the system There is an effect, and by minimizing the hardware related to the conventional data transmission and reception is an effect that can improve the economics according to the system configuration.
