DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with the operation of the structural means of the present invention with reference to the drawings.

2 is a flowchart illustrating a method for converting a protocol of the present invention, FIG. 3 is a system environment diagram of a method for storing voice data using the protocol conversion method of the present invention, and FIG. 4 is a flowchart illustrating a method for storing voice data using a protocol conversion method of the present invention. 5 is a system environment diagram of a remote diagnosis method using the protocol conversion method of the present invention, and FIG. 6 is a flow chart of a remote diagnosis method using the protocol conversion method of the present invention.

First, a preferred embodiment of the protocol conversion method used in the voice data storage method and the remote diagnosis method, which is one of the present inventions and another invention, will be described with reference to FIG. 2.

FIG. 2 (a) shows a procedure flow of a method of converting an Ethernet packet into serial data (hereinafter referred to as "Ethernet to Serial Conversion"). Ethernet packet is input through S10 (hereinafter, the protocol converted to send a 'packet' entered into the LAN port to the serial port is defined as 'data').

When the packet arrives to perform a series of operations for converting the Ethernet packet through the LAN port of the gateway into serial data, an interrupt is applied (S11) (hereinafter, referred to as a packet arrival interrupt). Then, it is determined whether a packet arrives at a predetermined port in advance (S12).

This means that the protocol conversion function works only when the port is entered in advance, and the Ethernet packet enters the port other than the designated port.

As a result of the determination, when the Ethernet packet does not enter the predetermined port in advance, voice processing or signal processing is performed as in the operation of a general gateway (S13). When the Ethernet packet enters the predetermined port, the protocol conversion function is performed. It works.

The Ethernet packet entering the designated port is continuously stored in the serial storage means (meaning the storage means used for converting the Ethernet packet into serial data) by the operation of the Ethernet task. The Ethernet task refers to a task that performs a protocol conversion function and performs an operation of storing an Ethernet packet coming into a LAN port in a serial storage means while continuously operating (S14).

The storage means may be a general memory, and may be interpreted as a register or a buffer.

A serial interrupt is generated to perform an operation for converting the Ethernet packet continuously stored in the serial storage means into serial data and sending it to the serial port (S15).

When the serial interrupt occurs, the packets stored in the serial storage means are transferred to the serial port in order by the operation of the serial task. The serial task refers to a task that performs an operation of sequentially transferring Ethernet packets in the serial storage means to the serial port (S16).

Next, the protocol conversion method related to the case where the serial data transferred to the serial port by the Ethernet-to-serial conversion as described above performs a corresponding function in the specific device and then delivers the specific data to the gateway again.

Figure 2 (b) is a method of converting the serial data input to the serial port of the gateway into an Ethernet packet transmitted to the outside by the LAN port by the protocol conversion method (hereinafter referred to as "serial to Ethernet conversion") Shows the flow of the procedure.

When serial data is input to the serial port of the gateway from the outside to the serial, an interrupt indicating that the serial data has arrived for protocol conversion of the serial to Ethernet conversion occurs (S20 to S21).

After the interrupt is generated, it is determined whether the serial data is input to the designated serial port, which is reserved in advance, and when the serial data is not input to the designated serial port, the operation of the general gateway is performed (S22 to S23). ).

If the serial data is input to the designated serial port as a result of the determination, the protocol conversion function of serial-to-Ethernet conversion is performed. Therefore, serial data inputted to the designated serial port by the operation of the serial task continues in order to the Ethernet storage means. Save (S24).

The serial task is a task for continuously storing serial data coming into the serial port in the Ethernet storage means in order in the protocol conversion function of serial-to-Ethernet conversion. The storage means generally means a memory, and a register or buffer This is an example.

Generates an Ethernet interrupt to convert the serial data stored in the Ethernet storage means into an Ethernet packet and outputs it to the LAN port, and when the Ethernet interrupt occurs, the serial stored in the Ethernet storage means by performing an operation of the Ethernet task. Output data to LAN port as Ethernet packet (S25 ~ S26).

The Ethernet task is a task that performs an operation to continuously output the Ethernet packet stored in the Ethernet storage means to the LAN port.

By the protocol conversion method consisting of the Ethernet-to-serial conversion and the serial-to-Ethernet conversion as described above, the gateway can operate as an effective gateway by connecting the LAN port and the serial port.

Next, an embodiment of a voice data storage method using the protocol conversion method described above with reference to FIGS. 3 and 4 will be described in detail.

As shown in FIG. 3, an IP phone extension subscriber 1 and an external caller 2 want to talk to each other through a gateway 4. At this time, the voice of the extension subscriber is converted into a network packet 6 and arrives through the LAN port 7 of the gateway 4.

The packet 6 is converted into an analog voice signal 9 by the gateway 4 and sent to the PSTN interface unit to make a call with the external caller 2. On the contrary, the analog voice signal of the external caller is received from the PSTN interface unit. Packetized over the RTP network, routed to the final destination of the station subscriber to make a call.

An embodiment for storing the contents of a call in a predetermined storage means while the call is in progress will be described with reference to FIG. 4.

First, the extension subscriber presses the function button of the start of the call storage to send the IP packetized call voice to the serial port and store the call in the storage means of the PC (S30). Then, the information that the function button is pressed is packetized and transmitted to the central processing IP module (S31).

The central processing IP module, which has received the packet having the information of the storage start function button press, analyzes the packet, and if it is determined that the packet information is required for voice storage, the voice call made by the IP extension subscriber and the external caller to the gateway. Creates and sends an event packet to start the storage of the data of the content (S32).

The gateway, having received the event packet through the LAN port, generates predetermined command data with the PC application software through the serial port and starts sending the data to the PC connected through the serial port in order to start storing voice data in the storage means of the PC (S33). ).

Then, the event data corresponding to the start of storing voice data is sent. When the PC is activated in advance and event data corresponding to the start of voice data storage arrives from the serial port of the gateway while the PC serial port is also initialized, the PC opens a file and prepares to store voice data (S34).

In such a situation, the IP extension subscriber and the external caller will continue to talk, and the call contents will be delivered through the gateway.

After the gateway is ready to store the data in the PC and waits for the voice data, the gateway converts the voice packets received through the LAN port of the gateway into serial data by a protocol conversion method (Ethernet to Serial) and transmits them to the serial port. (S35 to S36).

When the serial data (voice data) transmitted through the serial port is received from the serial port of the PC, voice data is recorded and stored in a file of the storage means by the operation of the PC application software (S37). Subsequently, if the call of the IP extension subscriber and the external caller continues, voice call data is continuously recorded in the file and continues until a command corresponding to the end of voice data storage is received (S38).

If the IP extension subscriber ends the call while the voice data storage operation is continuously performed, the event signal for ending the call is sent to the central processing IP module or the voice data storage end function button is pressed. The event packet of the press is transmitted to the central processing IP module (S39).

The central processing IP module receiving the call termination event packet transmits a packet (voice data storage termination command packet) of the information indicating that the call is terminated to the gateway, and the gateway sends a predetermined command to notify the serial port of the termination of voice data storage. Create and send data (S40 ~ S41).

Upon receiving the voice data storage end command data from the serial port, the PC terminates the voice data storage by the operation of the PC application software and closes the data storage file (S42).

As described above, the voice call data can be sent to the serial port of the gateway by a protocol conversion method (Ethernet-to-serial conversion) at the gateway, and stored in a PC having a storage means.

Next, with reference to Figures 5 and 6 will be described in detail a preferred embodiment of a remote diagnostic method using a protocol conversion method of one of the present invention.

5, the serial port 54 of the gateway 52 and the serial port of the specific device installed in the same exchange to diagnose the status or problems of the specific devices 55 in the exchange without the network function (the LAN port is not present). The port is connected to the serial line 56.

In this state, the administrator remotely connects to the LAN port 53 of the gateway 52 by using the PC 50, and serially sets the gateway 52 to a specific device 55 to be diagnosed using a protocol conversion method. Remote diagnostics can be made by passing a command.

Referring to Figure 6 will be described in detail a preferred embodiment of the remote diagnostic method using the protocol conversion method in the above system environment.

Once the administrator runs the administrator's PC to diagnose the device remotely, run the communication software to enable communication and connect to the gateway connected serially with the device to be diagnosed. In this case, the communication connection is made to the TCP port of the gateway via TCP / IP communication (to the communication port designated in advance with the IP address of the gateway at the remote place) (S60 to S61).

When the gateway receives an access request by the administrator and confirms that the connection is made to the designated TCP port in advance, the gateway detects that the connection is for serial port switching, converts the incoming packet to serial, and delivers it to the serial port. I am preparing (S62 ~ S63).

In this state, the administrator (who developed a device without a LAN port) inputs a diagnostic function or a problem tracking command for the device to be diagnosed, and the command is transmitted as an Ethernet packet to the gateway through the Internet ( S64 ~ S65).

The Ethernet packet inputted to the gateway is converted into serial data by the protocol conversion method of the gateway, and the converted serial data is output to the serial port (S66 to S67).

When the serial data corresponding to the command output to the serial port of the gateway is input to the serial port of the device to be diagnosed and performs functions corresponding to the command, and outputs the execution result through the serial port of the device to be diagnosed. The serial port of the gateway receives serial data as a result of the diagnosis (S68).

The gateway receiving the serial data as the diagnosis result converts the serial data into an Ethernet packet so that the serial data can be transmitted through the LAN port and transmits the serial data to the administrator (S69 to S70).

By viewing the delivered diagnosis result, the administrator may grasp the diagnosis and take necessary measures (S71).

According to the present invention having the configuration operation and embodiment as described above, by providing a protocol conversion method has an effect that can provide an improved efficient gateway by connecting the LAN port and the serial port in the gateway.

In addition, by the protocol conversion method, the communication switch has been extended to the serial port and the LAN port by the development of a gateway or access board into which a network (LAN port) enters as the current exchange is advanced. Since only a serial port exists, existing boards also have the effect of operating as if they had a LAN port.

In addition, if a serial port is connected between the gateway and the existing board to operate the existing board as if it is a LAN port, the access board without the LAN port can also be remotely diagnosed and the engineer who developed the existing board needs to diagnose the board. It can be usefully used for remote diagnosis and tracking.

On the other hand, the use of LAN port in the exchange is the majority of the use of Voice Over IP (VOIP) call processing, so when a packetized voice needs to be stored, serial data is relayed to the storage medium of the PC without any special equipment. Can be stored on a PC, which can be used as evidence for future problems.
