Hereinafter, an overall flowchart of diagnosing a service quality using the network service quality diagnosis system of the portable Internet system according to the present invention will be described.

3 is a flowchart illustrating in detail an overall algorithm for diagnosing network service quality using a wireless network service quality diagnosis system of a portable Internet system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, when executing a diagnostic measurement, a diagnostic command (hereinafter, referred to as DM) is input to a diagnostic server 100. A trace command is input (S100).

Then, the diagnostic server 100 performs an information search of the portable terminal (hereinafter, referred to as 'DM measurement terminal' in FIG. 2) of the diagnostic device for portable terminal to be measured DM. (S200) At this time, the diagnostic server Inquiring the database (DB) of the DM measuring terminal (100) (S210), and inquiring (S220) the status information of the terminal to be measured DM through the interworking network management server 110, the DM measuring terminal database (DB) Information on the normal state, power on / off, and corresponding service base station of the terminal to be measured in DM can be checked.

After performing the step S200, when the DM measurement terminals that can be measured are confirmed, N DM terminals to be measured are selected among the DM measurement terminals. (S300) After the corresponding terminal to measure the DM is selected, the test scenario in the diagnostic server 100 Each measurement condition is input (310). In step S310, when the measurement condition is inputted, it is linked with the GIS Map (S400), and when the latitude, longitude, base station name and address are input, the measurement section and location are determined on the map of the corresponding area. The set time, call retention time, etc. are determined.

When the input of the measurement condition is confirmed to the terminal to be measured such DM (S320), the user sets the desired measurement data logging mask (Logging Mask) setting input (S330). Here, the meaning of 'logging mask' means to select and store only the measurement result to be stored among the measurement results. For example, if there are 20 items that can be stored in the measurement result (receive strength, signal-to-interference ratio, terminal transmission power, base station related parameters, etc.), the user may select only the desired measurement items (receive strength, signal-to-interference ratio) from 20 items. will be.

 If there are more terminals to measure DM (340), if there is more, return to step S300 to select another terminal to measure the DM and performs the procedure from step S300 to step S330. In the present embodiment, it will be described assuming that there are N terminals 310 to measure DM. As such, the input of the measurement conditions and the measurement data for the N DM terminals 310 to be measured is completed.

Next, the diagnostic server 100 generates a DM test scenario task according to the measurement condition (S400), and transmits a DM test scenario to each base station 200 (S410). The transmitted DM test scenario is transmitted to the N DM measuring terminals 310 through the base station 200 (S420), and the N DM measuring terminals 310 are tested by the diagnostic server 100 through the base station 200. In operation S430, the diagnostic server 100 waits for the measurement result in the standby mode to collect the measurement result after acknowledgment S440.

Next, the N DM measurement terminal 310 and the interface device 320 analyzes the contents of the DM test scenario and waits for the DM measurement in order to perform the DM measurement according to the DM test scenario. DM measurement is performed. (S500) N units of DM measurement terminals 310 transmit the measurement results measured according to the respective measurement conditions to the diagnosis server 100. (S510) In steps S500 and S510, A detailed execution procedure will be described in detail later with reference to FIG. 4.

Finally, the diagnostic server 100 collects / stores the measurement results transmitted from the N DM measurement terminals 310 (S600), and the administrator outputs and analyzes the measurement results (S610), and then the diagnostic server 100. Terminate the DM trace (S700).

4 is a flowchart illustrating a procedure of performing measurement according to a driving algorithm of a DM measurement terminal and an interface device according to a DM test scenario in steps S500 to S510 of FIG. 3 according to an exemplary embodiment of the present invention.

Referring to FIG. 4, first, a DM test scenario command of the diagnostic server 100 is received (T100) or a user directly inputs a DM test scenario in a field (T110).

The DM measurement terminal 310 and the interface device 320 receive a DM test scenario (T120) and transmit whether or not to receive the DM test scenario (T130). In this case, in the case of inputting a measurement command (T110) by the field user, the step T130 may be omitted.

Next, the measurement standby mode is displayed through the diagnosis apparatus 330 and at the same time, the measurement is switched to the standby mode, and transmits the measurement standby mode to the diagnostic server 100. (T200)

The measurement standby mode checks and determines whether the conditions according to the DM test scenario are met when the conditions match the latitude and longitude, the measurement start time, and the corresponding local address of the measurement section set in the DM test scenario. )

If the condition is not set in the DM test scenario, it is the measurement standby mode (T200), and if the condition is met, the network service quality measurement is performed according to the DM test scenario. (T300) At this time, the diagnostic server 100 or a real-time user from the field user A command is received and the measurement result is transmitted to the diagnostic server 100 in real time. (T305) Here, a block diagram of transmitting the measurement result to the diagnostic server 100 and the user in real time will be described in detail with reference to FIG. 5. .

Receiving a command in real time from the diagnostic server 100 and the field user is to reflect the measurement changes caused by the command when an event such as a scenario change request occurs during the measurement. In addition, when an event such as forced termination occurs, when the user wants to re-measure later, the process returns to the state of step T120 again and eventually switches to measurement standby mode (T200).

When the DM test scenario measurement execution step is completed by transmitting the real-time measurement result without the event such as the scenario change or forced termination described above, it is determined whether the DM test scenario measurement is completed.

The criterion checks whether the measurement meets the conditions defined by the DM test scenario, and checks whether or not the logging is completed for the measurement result upon completion (T400). Here, logging means the measurement result. It says to save. At this time, whether or not logging is performed by checking whether logging is performed through command transmission / reception with the diagnostic server 100 or checking a memory state in the diagnostic device 300 for a portable terminal.

Finally, the mobile terminal 310 and the interface device 320 reports the measurement completion to the diagnostic server 100 and the field user. (T410) Then, the measurement completion command is received from the diagnostic server 100 or the field user. Measurement of the DM test scenario is terminated (T420), and the measurement of the DM test scenario is terminated (T430). If the measurement completion command is not received from the diagnostic server 100 or the field user, the measurement is switched back to the measurement standby mode and the diagnostic server 100 is returned to the diagnostic server 100. Informs the measurement standby mode. (T200)

5 is a block diagram (a) of a transmission flow in which a DM measurement terminal transmits a DM test scenario measurement result in real time in step T305 of FIG. 4, according to an embodiment of the present invention; b).

Referring to FIGS. 5A and 5B, first, the DM test scenario measurement result of FIG. 5A is received from the receiver P100 of the DM measurement portable terminal 310 from the receiver P100 of the interface device 320. The data is stored in the buffer or the storage device D200 through the I100.

The interface device transmitter I200 transmits the measurement result to the DM measurement portable terminal 310 transmitter P200.

The DM measurement portable terminal 310 transmits (P200) traffic data including control signals for maintaining a communication channel with the base station 200 and measurement results received through the interface unit 320 transmit unit I200 ( Traffic Data) is transmitted together.

As a result, as shown in FIG. 5 (b), the measurement results are changed in real time according to the quality of the wireless section while changing from the picture form of O100 to the form of O200 according to the wireless environment. That is, when the quality of the wireless section is good, the communication data can be transmitted a lot, so that the measurement result is loaded on the control signal and the maximum data that can be transmitted in the communication channel and transmitted (see FIG. 5 (a)). 0100), in a state in which the wireless section is in a bad state, only a control signal for the purpose of maintaining the minimum communication is not transmitted (FIG. 5 (b) 0200).

Since the amount of data to be transmitted changes according to the quality change of the wireless section as described above, the transmitter P200 of the DM measurement mobile terminal 310 transmits the measurement result according to the amount of traffic data allocated or transmitted. ) To transmit to the channel.

The transmitted measurement results are sent by extracting only the data for real-time transmission defined in the field user or DM test scenario. In actual implementation, the interface device 320 transceiver unit (I100 ~ I200) and the buffer or storage function unit (D200) and the diagnostic S / W block and S / W manager (D100) for the portable terminal is developed by including in the actual mobile terminal Alternatively, as shown in the block diagram of FIG. 4, it may be implemented in the form of an exterior.
