Abstract

A method for optimizing the performance of the code division multiple access system and the air field environments is disclosed. The invention includes the step of connecting a CDMA mobile station to a PC (Personal Computer), the step of connecting a GPS (Global Positioning System) to the PC, the step of operating a DM (Diagnostic Monitor) under a windows OS (Operating System), the step of requesting desired data to be transmitted to the mobile station by the DM, the step of measuring corresponding items and the present state [OF WHAT?] and transmitting the measured data to the DM, the step of requesting the data of the present position to the GPS by the DM, the step of transmitting the data of the present position to the DM by the GPS, the step of analyzing the data received from the mobile station and the GPS by the DM, and the step of displaying the analyzed results.

Claims

1. A method for optimizing the performance of the CDMA (Code Division Multiple Access) system and air field environments, comprising the steps of:

(i) connecting a CDMA mobile station to a Personal Computer (PC) having a hard disk drive for collecting data;

(ii) connecting a Global Positioning System (GPS) to the PC;

(iii) operating a DM (Diagnostic Monitor) under a windows Operating System (OS) in said PC;

(iv) making a data request to the CDMA mobile station by the DM; and

(v) measuring said requested data and the state of said mobile station, and transmitting said measured data to the DM;

(vi) making a request for present position data to the GPS by the DM;

transmitting the present position data to the DM by the GPS;

(vii) analyzing the transmitted data received from the mobile station and the GPS by the DM; and

(viii) displaying said analyzed results,

wherein said analyzed results are displayed on the screen through a PN (Pseudo random Noise) histogram and a voice activity function.

2. The method as set forth in the claim 1, wherein the DM is a Samsung Diagnostic Monitor (SDM).

3. The method as set forth in the claim 1, wherein the mobile station and the GPS are connected to the PC through respective communication ports of the PC.

4. The method as set forth in the claim 1, wherein the DM periodically requests data from the mobile station and the GPS.

5. The method as set forth in the claim 1, wherein a scan size of the searcher window and the output range of the Ec/Io may be adjusted.

6. The method as set forth in the claim 5, wherein said adjustment of the scan size and the output range of the Ec/Io is performed by direction keys of the PC searcher window.

7. The method as set forth in the claim 6, wherein the received data to be analyzed is transmitted to the mobile station.

8. The method as set forth in the claim 7, wherein the received data includes:

status display information, comprising mobile station information, the call status information, and channel information;

searcher information, for displaying the Ec/Io information received from the mobile station to the screen, the Ec/Io information being scanned as large as the size of the windows defined for each PN offset;

finger information, for displaying the Ec/Io information for each finger when receiving the finger information of the mobile station;

AGC (Automatic Gain Control) display information, for displaying the transmitting and receiving power and the value of the gain adjustment;

frame information for displaying the frame information of the paging channel, the access channel, the reverse traffic channel, and the forward traffic channel; and

voice activity information according to a voice rate.

9. The method as set forth in the claim 1, wherein when a log is started, the log masked items transmitted from the mobile station and the GPS are collected.

10. The method as set forth in the claim 1, wherein the display screen to display the analyzed results can be aligned to allow an operator to view the results.

11. The method as set forth in the claim 10, wherein said alignment of the display screen is performed by selection of the corresponding tool bar through a function key or the mouse of a PC.

12. The method as set forth in the claim 1, wherein the PN histogram can display the Ec/Io histogram for each PN offset in periodic time intervals.

13. The method as set forth in the claim 1, wherein the voice activity function is performed the fixation according to a voice rate.

14. The method as set forth in the claim 1, wherein communication between the mobile station and the GPS and the DM is asynchronous HDLC (High level Data Link Control) RS-232C.

15. The method as set forth in the claim 1, wherein said DM arranges and unifies the collected data when optimizing a field.

16. The method as set forth in the claim 1, wherein when the DM is in use, other tools of the PC can be concurrently utilized.

17. The method as set forth in the claim 1, wherein the capacity of the DM to collect the data is limited only by the capacity of the hard disk drive.

18. A method for optimizing the performance of a CDMA (Code Division Multiple Access) system and air field environments, comprising the steps of:

(i) connecting a CDMA mobile station to a Personal Computer (PC) having a hard disk drive for collecting data;

(ii) connecting a Global Positioning System (GPS) to the PC;

(iii) operating a DM (Diagnostic Monitor) under a windows Operating System (OS) in said PC;

(iv) making a data request to the CDMA mobile station by the DM;

(v) measuring said requested data and the state of said mobile station, and transmitting said measured data to the DM;

(vi) making a request for present position data to the GPS by the DM;

(vii) transmitting the present position data to the DM by the GPS;

(viii) analyzing the transmitted data received from the mobile station and the GPS by the DM; and

(ix) displaying said analyzed results,

wherein a scan size of the searcher window and the output range of the Ec/Io may be adjusted, said adjustment of the scan size and the output range of the Ec/Io is performed by direction keys, the data to be calculated is transmitted to the mobile station, and

wherein the data includes;

status display information, comprising mobile station information,

the call status information, and channel information;

searcher information, for displaying the Ec/Io information received from the mobile station to the screen, the Ec/Io information being scanned as large as the size of the windows defined for each PN offset;

finger information, for displaying the Ec/Io information for each finger when receiving the finger information of the mobile station;

AGC (Automatic Gain Control) display information, for displaying the transmitting and receiving power and the value of the gain adjustment;

frame information for displaying the frame information of the paging channel, the access channel, the reverse traffic channel, and the forward traffic channel; and

voice activity information according to a voice rate.
