Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

The wireless management system for the data service proposed in the present invention is basically implemented simply by adding one monitor board (m-CDPA) to the IWF for the existing wireless data service, and the added monitor board is a circuit data processor assembly. (Circuit Data Processor Assembly; hereinafter abbreviated as CDPA) The board is used as it is, but a task is added to bypass the data exchanged with the operating system (OS) and application through the input / output port to the modem.

In the present invention, when a data call attempt by a mobile terminal occurs, the called party number is analyzed. Virtual Terminal) function.

1 is a flowchart illustrating a data call setup procedure for monitoring an IWF according to the present invention.

Referring to FIG. 1, FRICC (4) / FRIL2 (2) / FRIL3 (3) is a software block responsible for linking, call processing, packet processing, etc. between the IWF and the ASS-F of the switching center 1, and the CDICC (5). ) / MDMCC 6 is a software block responsible for call processing and resource management in the IWF.

The CDPA 7 has eight modem channels and is a board having protocol and data traffic related applications with a mobile terminal.

After the protocol setup procedure is completed between the mobile terminal and the application of the CDPA (S1 to S18), and the Transmission Control Protocol / Internet Protocol (TCP / IP) is opened, the modem resource management and call processing block MDMCC (6) analyzes the called number.

At this time, if the called number is a predetermined specific number, i.e., a number indicating a call for the system monitor, the MDMCC 7 activates the m-CDPA 8 to activate the traffic for actual data. The allocated modem and the modem in m-CDPA 8 are switched and connected (S19 to S24).

Accordingly, the Monitor Task according to the activation of the m-CDPA 8 enables the Modem Control Task to process the input / output address of the board.

In this case, the data terminal (laptop) connected to the mobile terminal can monitor the m-CDPA (8) board, and then call the virtual terminal function to monitor the corresponding block and board.

Referring to FIG. 2, the CDPA 30 board in the IWF is an 8-modem channel and an application for data paths, protocols, and data traffic between the mobile terminal 10 and a public switched telecommunication network modem. It consists of.

When attempting a data call of the mobile terminal 10, a modem channel is allocated from a higher level, a radio link protocol (RLP), a point-to-point protocol (PPP), Opening traffic paths through Transmission Control Protocol (TCP) and Internet Protocol (IP) procedures, and also through the Primary Rate Interface (PRI) resources, Alternatively, a data path with another mobile terminal 10 is opened.

M-CDPA (40) board according to the present invention is a board for monitoring only the other upper block in the IWF, the same as the conventional in hardware, but software communication with the conventional CDPA (30), the input and output data of the board It is a simple shape having only a module that bypasses the modem 41 added for monitoring.

Referring to the operation of the m-CDPA (40) board shown in Figure 2 as follows.

The CDPA modem 31 assigned by the mobile terminal 10 to show the call number reports the called number to a higher call processing block through a protocol setup procedure with the mobile terminal 10.

At this time, if the called number is a specific number for a predefined system monitor, the call processing block switches the modem 41 in the m-CDPA 40 and the modem 31 assigned in the CDPA 30 to switch both boards. Set the data path between (30 and 40).

When the data path between the two boards 30 and 40 is established, the m-CDPA 40 generates a monitor task and calls a virtual terminal function.

As a result, the path A-B-C using the virtual terminal of the m-CDPA 40 is established. That is, the traffic path between the mobile terminal 10 and the BSCA main processor assembly (hereinafter, abbreviated as BMPA) 50, which is a target board to be monitored, is set, and thus the mobile terminal 10 Can be monitored as if the cable according to RS-232C standard is connected to the target board.

Here, referring to the monitor task of the m-CDPA 40, the screen provided by the operating system (OS) and the application of the m-CDPA 40 can be substantially seen in the terminal connected to the mobile terminal 10. Is a monitor screen, which is implemented by a monitor task.

As shown in FIG. 3, the monitor task 44 of the m-CDPA 40, which is a method proposed by the present invention, is a traffic data control task for processing traffic data in an existing CDPA using data written in an input / output address. Handle Task (43) directly, through a personal computer (especially a laptop) connected to a mobile terminal, such as data input and output on the data path through the RS-232 input / output serial port 45 described above. To do the same.

In addition, the monitor task 44 allows the modem control task 42 to process input / output addresses of the board as the m-CDPA 40 is activated as described in FIG. 1. .

In this case, the data terminal (laptop) connected to the mobile terminal can monitor the m-CDPA 40 board, and then call the virtual terminal function to monitor the block and board.

A virtual terminal is a function that allows you to monitor one board, rather than connecting a serial cable to that board to monitor it.

As shown in FIG. 4, when the A board 100 specifies a system address of the B board 200 to be monitored through a command, the B received a designation through inter-processor communication (IPC). Operating system (OS) 220 of the board 200 is a raw data (Raw Data) form the data output through the RS-232 input and output port 210 of the magnetic board 200 through an inter-processor communication (IPC) packet To send to the A board 100 that performed the command.

In addition, the user's command received through the RS-232 input / output port 110 of the A board 100 is similarly transmitted to the B board 200 through an interprocessor communication (IPC) packet. For this to be possible, the operating system (OS) 120 must provide a Kernel Call that can utilize it at the application level.

As described above, the present invention adds a monitor line data processor assembly (m-CDPA) in the network interlocking device to monitor the status of each system board, so that an overall system of the system is not required even if the engineer or the manager is located. The status and error conditions can be monitored via their personal computer (or laptop), which has the effect of properly managing the system.
