The present invention relates to a method and system for monitoring and notifying a plurality of RF parameters in a DM (Diagnostic Monitor) of a wideband code division multiple access (WCDMA) system. More specifically, the DM determines a plurality of RF parameters to be monitored, sets monitoring conditions for the RF parameters, selects a notification method for notifying when the measured values of the plurality of RF parameters meet the monitoring conditions, and then directs the DM to the mobile communication. Connect to the terminal and measure a plurality of RF parameters and if the measured values of the RF parameters meet the monitoring conditions, the operator will be notified of the abnormality of the radio wave environment by the measured values of the plurality of RF parameters by the selected notification method. A method and system for monitoring and notifying a plurality of RF parameters in an apparatus.

As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while providing a text message service to complement the voice call service, a wireless Internet service has recently emerged to provide an Internet communication service to a user of a mobile communication terminal through a wireless communication network.

Accordingly, mobile communication service subscribers can receive various types of information such as news, weather, sports, stocks, exchange rates, and traffic information in various forms such as text, voice, still image, and video through wireless Internet service.

As a result of the development of mobile communication technology, the service provided by the mobile communication system is developing not only a voice service but also a multimedia communication service for transmitting circuit data, packet data, and the like.

In order to provide such a service, a mobile communication system has been developed through a first generation analog AMPS (Advanced Mobile Phone System) method and a second generation cellular (PCS) / personal communication service (PCS) method. For example, IMT-2000 (International Mobile Telecommunication 2000) (eg, CDMA2000 1X, 3X, EV-DO, WCDMA, etc.), which is a third generation mobile communication system established by ITU-R, is commercially available.

IMT-2000 is CDMA 2000 1X, 3X, EV-DO, WCDMA, etc., and supports data transmission in IS-95A and IS-95B networks using IS-95C network, which has evolved from IS-95A and IS-95B networks. It is a service that can provide wireless Internet at a transmission speed of 144 Kbps much faster than the speed of 14.4 Kbps or 56 Kbps. In particular, by using IMT-2000 service, it is possible to provide various multimedia services (AOD, VOD, etc.) at higher speed as well as improving existing voice and WAP service quality.

Here, the WCDMA method is a mobile communication system asynchronously implemented in the IMT-2000 system. The wireless access method for communication between the base station and the mobile terminal uses the CDMA method, but the mobile communication network related technology is GSM (Global System for Mobile Communications). Is based on network technology. The WCDMA method does not need to use Global Positioning System (GPS) to synchronize the entire base station, supports international roaming service, widens the frequency bandwidth to 5 MHz, and has a data transmission rate of 2 Mbps, which is suitable for high-speed data transmission. In addition, by providing diversity according to the reverse call quality which cannot be provided in the conventional IS-95 and GSM methods, the call and data transmission performance is relatively good even in a poor communication environment. However, since the WCDMA method does not support backward compatibility with the existing CDMA and GSM methods, a new mobile communication network must be established and a mobile communication terminal supporting the WCDMA method should be used.

On the other hand, DM is a device that collects and analyzes radio wave environment data such as call quality between the mobile communication terminal and the base station and whether there is an abnormality in the mobile communication network, and optimizes the mobile communication network so that the mobile communication services provided by the WCDMA system can maintain stable quality. It is a device for obtaining data for trouble shooting.

Here, the radio wave environment data collected and analyzed by the DM may include RF parameters. The RF parameter is a factor for knowing the propagation environment of the measurement area, and when the DM is used, the RF parameter can be measured by analyzing radio signals transmitted and received between the mobile communication terminal and the base station. Here, the radio wave environment refers to a radio communication environment of a corresponding area determined in consideration of the strength of a wireless signal transmitted and received between a mobile communication terminal and a base station, noise intensity, transmission error rate when transmitting and receiving wireless Internet data, and the like. The better, the higher quality wireless communication services can be provided in the area.

In order to collect the radio wave environment data in a specific area by using a DM, a field test is conducted. For this purpose, after connecting the DM with a mobile communication terminal, the radio environment of a specific area is observed while moving to a specific area by car. Done. The DM stores the measurement result in the measurement log, and may analyze the measurement log to determine whether there is an abnormality in the propagation environment.

In this case, when one driver performs the field test, it is difficult to find the abnormality of the radio wave environment by continuously observing the DM while driving. Therefore, the measurement log of the DM is analyzed after the field test. There is a problem that is difficult to analyze. In addition, even in the case of field tests in which two people work in groups and one person observes the DM, when the observer's concentration and attention decrease after a long time, the presence or absence of the radio wave environment at a specific point is observed. There is a problem in that the propagation environment cannot be accurately analyzed in real time because there is a case where it is impossible to pass.

In addition, the measurement result of the DM only tells only the measurement value of one RF parameter, there is a problem that there is no function to inform the propagation environment of the measurement area by analyzing the measurement value of a plurality of RF parameters.

Therefore, if there is an error in the radio wave environment of the measurement area, it is possible to detect and inform the operator in real time and to set the monitoring conditions for the plurality of RF parameters and analyze the measured values of the plurality of RF parameters. There is a need for a method that can notify the user in real time.

In order to solve this problem, the present invention determines a plurality of RF parameters to be monitored by the DM, sets a monitoring condition, and sets up a notification method for notifying when the monitoring conditions are met, and then the plurality of RF parameters measured by the DM. DM of the WCDMA system that can inform the operator of the radio wave environment condition by the measured value of a plurality of RF parameters by the set notification method when the measured value satisfies the set monitoring condition, and can determine whether there is an abnormality in the radio wave environment in real time.

5 is a flowchart illustrating a method of determining a plurality of RF parameters to be monitored by a DM and setting a monitoring condition and a notification method of the RF parameters according to a preferred embodiment of the present invention.

As shown in FIG. 5, when the initial screen is displayed by applying power to the DM 300, the DM 300 may provide a menu for setting a condition for monitoring RF parameters (S500).

In the above menu, it is determined whether to select a plurality of RF parameters or individual RF parameters (S502). When selecting a plurality of RF parameters, a list of RF parameters is displayed on a menu, and a plurality of RF parameters to be monitored can be determined from the list (S504).

 Here, the selectable RF parameters include RX Power, TX Power, RSCP, BLER, SIR, Ec / Io and TPC History, etc., and define new RF parameters according to the needs of the operator and measure them in the DM 300. Can be added to the list of parameters.

When the DM 300 determines a plurality of RF parameters to be monitored, a monitoring condition of the determined plurality of RF parameters is set, and a notification method for notifying when the measured values of the plurality of RF parameters meets the monitoring conditions is set (S506). ). The monitoring conditions of the plurality of RF parameters can be set by specifying a range of measured values. For this purpose, the upper and / or lower limits of the plurality of RF parameter measurement values may be set so that the monitoring condition may be set when the measurement value is above the specified value and / or below the specified value.

After setting the monitoring condition, a notification method for notifying the measured value of the plurality of RF parameters meeting the set monitoring condition is selected. The notification method may include a notification method using a text, a notification method using a voice, a notification method using an image, and the like, and may use a plurality of RFs to an operator using one of the above-described notification methods or two or more at once.

For example, if RX Power and Ec / Io are selected as RF parameters to monitor, and the measured values are smaller than the specified values as monitoring conditions, and the notification method is selected, RX Power and Ec / Io are selected. If the measured value of satisfies the set monitoring condition, input the message 'RF environment bad' as the radio wave environment of the measurement area to inform the operator that the measured value of RX Power and Ec / Io is low and the RF environment is bad. The operator can be notified by the set notification method.

The case of smaller than 13 was set as a detection condition, and the notification method was set to the notification method by text, voice, and video. Each notification method uses 'Bad RF' for text, 'RF environment bad' for voice, and 'right hand pointing with finger' for video, and the radio wave environment status by measured values of RX Power and Ec / Io. Will be displayed.

Therefore, if the conditions for monitoring RX Power and Ec / Io are set under the above-described conditions, the above-mentioned notification is provided when the RX Power value measured by the DM 300 is less than -90 dBm and the Ec / Io value is less than -13. The operator will be informed of the radio wave environmental status of the measuring area.

When the measured plurality of RF parameter values meet the set monitoring conditions, the operator is notified of the radio wave environment state by the measured values of the plurality of RF parameters using text, voice, or video according to the designated notification method ( S706). Here, the DM 300 measures a plurality of RF parameters in real time, and when the measured values of the plurality of RF parameters meet the set monitoring conditions, the radio wave environment state by the measured values of the plurality of RF parameters using the above-described notification method. The notification may inform the measurement area and measurement time of the plurality of RF parameters.
