The field data measurement system 40 is connected with the operator management system 10, the mobile terminal 30, and the receiver 40 using the GPS, and receives the base station shape, system parameters, measurement data, and location information data therefrom, respectively. In addition, the configuration file provides a convenient user environment of the system.

Accordingly, the field data measurement system 20 can automatically detect the location and time that the system is currently measuring, allowing the field data analysis system 50 to be described later to accurately analyze the local distribution of CDMA field data. . Here, the CDMA field data is compared with the pilot energy Ec accumulated during one pseudo noise (PN) chip period for the reception level (Rx Level), the transmission level (Tx Level), and the total power spectral density (Io) in the reception bandwidth. Rate (Ec / Io) data, Frame Error Rate (FER) data, Adjust data, and the like.

The field data measurement system 20 uses the map data to provide information for displaying the measurement position as well as information on the distribution of CDMA field data in each region. In addition, the longitude and latitude of the current measuring position, the measurement time and the measured data value are displayed and saved as a file. In this case, the measurement data on the screen is displayed as a number and a graph on a portion of the screen or as a symbol along with the location and information of the base station on the map. Here, the symbol is filled with the color designated by the operator according to the size of the value.

2 is an exemplary view illustrating a configuration of a field data analysis system to which the present invention is applied.

The field data analysis system 50 displays CDMA field data obtained from the field data measurement system 20 or other devices on the screen and analyzes the same. For example, the measurement data from the field data measurement system 20 and the base station location and associated database received on-line or off-line from the operator management system 10 are simultaneously analyzed. .

The main functions of the field data analysis system 50 include processing and displaying measurement data, inputting and managing base station data, analyzing measurement data, and inputting / outputting other format data.

As described above, the field data measurement and analysis system 20 and 50 implements a function of measuring and displaying CDMA field data on a map in real time, reproducing the measurement data, and analyzing the measurement data so that the user can easily use it. In addition, many additional features can be added as required by field engineers.

3A and 3B are flowcharts of an embodiment of a field data analysis method according to the present invention.

First, a workspace is created in the field data analysis system 50 (301). At this time, the measurement data composed of binary data from the field data measurement system 20 is decoded in the workspace to generate a data module (DM) file and a message file.

The workspace is then opened (302) to determine if there is a field data (TOT) file (303). Here, the field data (TOT) file includes the data location, pilot energy / total power spectral density (Ec / Io), reception (Rx), transmission (Tx), adaptation, finger values, and the like. have.

As a result of the inspection, if there is no field data (TOT) file, the field data (TOT) file is generated from the data module (DM) file (304). If the field data (TOT) file is present, the field data (TOT) file is generated once more. Since there is no need to make the above, the field data (TOT) file for the data is loaded (305).

Next, a base station file database is constructed to display a function of displaying a base station on a screen based on a field data (TOT) file, an indication of hand-off, and information about each base station (306). Here, the base station file database is configured by reading information from files made for each Message Sequence Chart (MSC) based on a file made of Excel.

Next, when the data is reproduced or when the message is selected, a map in vector format suitable for the data is selected according to the latitude and longitude (307). Here, the map used may be cut into rectangles in a vector format and separated into regions of Seoul, Busan, and the nation. Therefore, after reading the data, it selects the area to which the data belongs, finds out which of the rectangles it divides, and loads the map automatically.

Then, it is determined whether there is a message file to show a message corresponding to each data (308).

As a result, if there is no message file, the data module (DM) file is analyzed (309) after generating a message file (310) and the workspace is stored (313), and if there is a message file, the workspace is immediately stored (313). .

If there is a user input in the field data analysis process, the user input process is performed according to the user's input. The processing of the user input is as follows.

First, it is analyzed whether there is a user input process (311).

As a result of the analysis, if there is no input processing by the user, the user waits for input processing by the user.

As a result of the analysis, if the user's input is a general input, a general input processing process is performed according to the requirement (312), and the state transitions to the standby state.

As a result of the analysis, if the user's input is an end input, the user input processing is terminated.

The general input processing process 312 according to a user's request is as follows.

If the user's input is input for statistical processing to process statistical operations on the data, select the data to be statistical and the statistical method (321, 322) to obtain the statistics of the selected data (323), and then display the output on the map. Output to the screen and the printer (324). Here, the statistical methods include cumulative probability statistics, probability density statistics, and profiles, and the statistics may be selected by selecting only a part of the data.

If the user's input is a change on the data display method to change the display of the data, the method of data to be displayed is selected (325), and the size, shape, type of data to be displayed, and filtering are performed. After changing the method of displaying the data in a manner (326), the data and the map are redrawn (327).

If the user's input is an input relating to the sequential display of the data in order to display the already measured data sequentially over time, the start point of the data is determined (328) until the user's interruption input (330), one data The output is repeated (329). Here, the hand-off of the base station is displayed while data is taken, and the change of the graph or the like is displayed.

If the user's input is an inquiry about the base station database in order to view various information about the base station, the user selects a desired base station and an inquiry item (331,332), and inquires the base station selected by the user from a pre-made base station database (333). Is displayed on the screen (334).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention shortens the time from measurement to analysis, and analyzes the location and base station information in real time in parallel, thereby enabling accurate analysis regardless of the user, and by analyzing the parameters between the terminal and the base station by location. It is efficient and economical with the ability to easily add multiple add-ons as required by field engineers.
