Provide a method.

Hereinafter, the present invention configured as described above will be described in detail with reference to the accompanying drawings.

That is, FIG. 1 is a diagram illustrating a configuration of a system for monitoring and analyzing poor voice quality of a mobile communication service according to an exemplary embodiment of the present invention.

As shown in Figure 1, the call sound quality failure monitoring and analysis system of the present invention, a plurality of mobile communication switch (M1 ~ Mn), billing data collection server 10, configuration DB server 20, sound quality monitoring / It consists of the analysis processing part 30, the client terminal 45, and the remote web terminal 50. FIG.

The plurality of mobile communication switch (M1 ~ Mn) is the billing data collection server as the call data for retry call analysis of the raw billing data (CDR1 ~ CDRn) generated by the call origination of the mobile subscriber terminal through the mobile communication network It will be transmitted to (10) in real time.

Here, the retry call means that the subscriber of the mobile communication terminal attempts to redial the call immediately after the call is shortly terminated due to poor voice quality or the like during the call setup with the other party. The call status can be identified by the billing data of the subscriber.

On the other hand, the billing data (CDR1 to CDRn) includes a terminal number (MIN), a prefix, a base station (BTS), a base station controller (BSC), a mobile communication exchange (MSC), and a route of a corresponding mobile communication terminal. ), The call type information is included, and whether the call is terminated normally at the end of the call, as well as the cause of the failure in case of a call failure or drop.

The billing data collection server 10 is equipped with a billing data database 15 for storing billing data, the billing data received in real time from each of the mobile communication switch (M1 ~ Mn) for a predetermined time (for example 5 minutes or 15 Minutes) and collectively transmit the sound quality to the sound quality monitoring / analysis processing unit 30.

The configuration DB server 20 is a configuration that stores the overall device information about the device constituting the mobile communication network, such as the base station, the base station controller, the mobile communication switch and the like, and subscriber information such as terminal number, prefix, etc. of each mobile communication terminal subscriber. The information database 25 provides the sound quality monitoring / analysis processing unit 30 with device information and subscriber information necessary for monitoring / analysis of poor voice quality.

The sound quality monitoring / analysis processing unit 30 is composed of a distributed environment for high speed data processing, and periodically receives raw billing data from the billing data collection server 10 for each billing data. To determine whether the call is a retry call, and to generate summary information of the analysis data for monitoring the sound quality by the determined retry call, which receives the raw billing data from the billing data collection server 10 Charging information dedicated database 35 for storing and retrying determination of each billing data and retrying call discrimination data in a database table for each network device, terminal number, route, and prefix. And a summary information database 40 for storing summary information generated as a result of the call discrimination.

Here, the charging information dedicated database 35 can read / write the raw charging data at a high speed, and also index the index for each billing data by call number and collection time into a memory hash structure. By saving and fast indexing, one-time memory index access to a specific terminal number enables offset access to all raw billing data in that time zone, and hashes the combination of the calling number and the called number. By detecting with the key value of (Hash), it is possible to detect high speed retry calls without using the existing looping method.

Meanwhile, as illustrated in FIG. 2, the sound quality monitoring / analysis processing unit 30 includes a retry rate summary processing block 55, a configuration information management processing block 60, and a table partition management processing block 65. , A web interface processing block 70, and a system management processing block 75.

The retry rate summary processing block 55 of the sound quality monitoring / analysis processing unit 30 is for each communication network device, terminal number (MIN), and route through the retry call determination data generated from the charging information dedicated database 35. In this case, the retry rate is calculated for each prefix, and summary information on the retry code is prepared based on the retry rate.

Here, the retry rate is obtained by dividing the retry lake with respect to the originating lake (that is, the retry lake / outgoing lake), and if the retry rate is more than a certain percentage, for example, 1.8%, it is regarded as sound quality defect. do.

In addition, the summary information based on the retry rate generated by the retry rate summary processing block 55 provides a function of detecting / analyzing a retry rate for a plurality of items, such as a mobile communication exchange, a base station controller, and a base station. Ability to classify bad sections by communication network device, route, and prefix, and to monitor / analyze by specific service, CFC code, routing number, originating subscriber (i.e. by call type and by subscriber) Monitor / analyze function), and each device has a trend of daily / hour unit, and if there is a small amount of call by system, the average value of 1 hour unit is used. Allows you to monitor / analyze the retry rate in minutes.

The configuration information management processing block 60 receives device information of the overall communication network device provided from the configuration DB server 20 and configuration information such as subscriber information of a terminal subscriber and manages components related to a retry call. The table partition management processing block 65 manages the configuration information related to the retry call as tabled information by base station, base station controller, mobile communication switch, terminal number, and prefix. do.

The web interface processing block 70 converts the analysis information of the retry call into web information data having a web protocol of HTTP and transmits the data to a remote place through the Internet network, and the system management processing block 75 Management of the overall system constituting the sound quality monitoring / analysis processing unit 30 is performed.

In addition, the client terminal 45 periodically receives and retrieves summary information stored in the summary information database 40 of the sound quality monitoring / analysis processing unit 30, thereby visually detecting a poor state of voice quality due to retry call detection. Is to monitor and analyze.

The remote web terminal 50 is located at a remote location with respect to the sound quality monitoring / analysis processing unit 30, and periodically receives summary information from the web interface processing block 70 through an internet network to detect a poor call quality. You will search visually.

Here, the client terminal 45 and the remote web terminal 50 monitors and analyzes the retry rate by call type, communication network device, and call state by summary information including the retry rate information. The retry rate monitoring / analysis for each call type is classified into a mobile terminal versus a mobile terminal, a mobile terminal (outgoing) versus a landline telephone (incoming), and a wired telephone (outgoing) versus a mobile communication terminal (incoming). The call of the mobile communication terminal to the mobile communication terminal is monitored by being divided into a call made in the same exchange and a call of another station.

In addition, the retry rate monitoring / analysis for each communication network device is to monitor and analyze the sound quality defect section by mobile communication switch, base station controller, base station, and route, and the retry rate monitoring / analysis by call state is completed. It can be classified into call and incomplete call to monitor the sound quality.

On the other hand, the retry call detected by the raw billing data in the charge information dedicated database 35 of the sound quality monitoring / analysis processing unit 30 is reproduced during a call by the retry call and the called party's response during call setup. In the call setup, the retry call is attempted to set the call back to the same terminal number after the end of the call due to poor sound quality in the ring back tone state after the call channel allocation by the call setup. The call retrying call means that the call is terminated due to poor voice quality in the state where the answering party is in progress after the call establishment attempt, and retry call setup using the same terminal number again.

Here, as shown in FIG. 3, the retry call is established within 4 to 10 seconds by a non-response of the called party after a specific terminal subscriber performs a call origination attempt and successfully allocates an outgoing channel. The call is terminated within the period (a2), and it is determined whether the call is retried with the same terminal number within the corresponding period (a3) within 35 seconds from the end of the call, to determine whether it is a valid retry call.

However, if a particular terminal subscriber finishes the call within 4 seconds after the origination attempt or after 10 seconds after the origination attempt, it is determined that it is not caused by a poor sound quality but by personal factors of the subscriber. Will be excluded from retry.

In addition, the retry call during the call is a period (b2) within 4 seconds to 30 seconds at the time of the call by the specific terminal subscriber attempts to set up a call and performs a response from the called party, as shown in FIG. The call is terminated, and it is determined whether the call is retried by determining whether the call is re-set with the same terminal number within the corresponding period (b3) within 35 seconds from the end of the call.

However, in the case of the retry call during the call, if the call is terminated within the corresponding period (b1) within 4 seconds from when the answering party proceeds or after 30 seconds have elapsed from the receiving party's response, It is determined not to be caused by a defect but by a personal factor of the subscriber and is excluded from the retry attempt.

In addition, the billing information dedicated database 35 is excluded from the retry call if the cause of call termination is the following, even if it meets the requirements of the retry call by the verification process, which is a route in Call Type 4. If the number starts with 19 (i.e., an announcement message such as power down is sent out), or if CFC is 24 (aspirator) in call type 6 (i.e., if a busy announcement is sent) If the call type is 4 and the digit number is 1501 (i.e., a data call occurs), and the CFC code is an item related to a fluorine call (i.e. redialing the charge data, This is the case when the call type is 4 and CFC 38 and 40 (that is, when the called terminal is busy or powered off).

In addition, the cause of the termination of the call to be excluded from the retry call is when the dial digit is 1544, 1588, 114, area code +114, a89, 00721 (that is, when the call is retried after the end of the call due to lack of internal line after answering). If the dial digit is 080 or local station number +080 (i.e., it is automatically terminated after sending out announcements due to lack of internal line after answering in ARS), and special service type is 32. (I.e., if you press a certain key to hide the calling number, two billing data will be created. If the holding time is "0" by 32), the dial digits are 02131, 0 ×× 131, 0 ×× 141. , 02100, 0 × 100, root number 1961-, dial digit 083-, dial digit 0101, 017200, 2000, dial digit 700, 011700, dial digit a (*) (I.e. wireless interface such as nate) Net voice call), a retry call of a subscriber who has retries five or more times in the same base station, or a retry call due to a busy or unanswered call.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 5.

First, the raw billing data (CDR1 to CDRn) generated in response to an outgoing signal from a plurality of mobile communication exchanges (M1 to Mn) are transmitted to the billing data collection server 10 in real time, and the billing data collection server 10 is provided. The raw data received in real time from each mobile communication exchange (M1 ~ Mn) is stored in the billing data database 15 and collected for a predetermined time (for example 5 minutes to 15 minutes), the sound quality monitoring / analysis processing unit 30 Is transmitted to (step S10).

In this state, the sound quality monitoring / analysis processing unit 30 stores the raw charging data received from the charging data collection server 10 in the charging information dedicated database 35, and retrievs an outgoing signal generated for each charging data. It is checked whether the call is recognized (step S12).

That is, the charging information dedicated database 35 determines whether or not the call signal generated by each charging data is a retry call (step S14).

As a result of the determination, if it is determined that the specific calling signal is a retry call having a retry with the same calling number, the charging information dedicated database 35 determines whether the retry call is a retry call during call setup (step S16). .

As a result of the determination, if it is determined that the retry call is a retry call during call setup, it is determined whether the call termination has been completed within a predetermined period (for example, 4 seconds to 10 seconds) after the call origination attempt (step S18).

On the other hand, if it is determined in step S14 that the retry call is not a retry call during call setup, it is determined to be a retry call during the call (step S20), and the call termination of the retry call during such a call is for a certain period (for example, 4 seconds to 30 seconds), or not (step S22).

According to the determination result of the step S18, the call termination of the retry call during the call setup is made within a predetermined period (for example, 4 seconds to 10 seconds), or the call termination of the retry call during the call is predetermined period according to the determination result of the step S22. If it is determined that the call is made within (for example, 4 seconds to 30 seconds), it is determined whether the retry call during the call setup or the retry call during the call is included in the exclusion item of the retry call (step S24).

As a result of the determination, if it is determined that the charging information dedicated database 35 does not include the retrying call during the call setup or the retrying call during the call, it is not included in the exclusion item of the retrying call. The data is uploaded to the database table by root and by prefix (step S26).

Then, the retry rate summary processing block 55 calculates the retry rate for each communication network device, terminal number, route, and prefix based on the charging data uploaded to the database table of the charging information dedicated database 35. (Step S28).

When the retry rate is obtained by the above step, the retry rate summary processing block 55 generates summary information for monitoring / analyzing the retry rate and stores it in the summary information database 40 (step S30).

Accordingly, the summary information database 40 stores the summary information created in the retry rate summary processing block 55, and the configuration information from the configuration DB server 20 which is subjected to data processing from the configuration information management processing block 60. In accordance with the present invention provides the sound quality analysis information by the retry call to the client terminal 45, the client terminal 45 can periodically monitor and analyze the retry rate through the sound quality analysis information by the retry call. (Step S32).

Also, the sound quality analysis information from the summary information database 40 is remotely connected to a remote web via an internet network through a web protocol processing through a web interface processing block 70 under the management processing of the system management processing block 75. Transmitted to the terminal 50 to enable the monitoring and analysis of poor sound quality even at a remote location.

On the other hand, it is determined that the call originating the charging data is not a retry call according to the determination of step S14, or the call termination of the retry call during call setup has not been made within a predetermined period according to the determination of step S18 (that is, 4 Call termination within seconds or after 10 seconds), the call termination of the retry call during the call is not determined within a certain period of time (that is, call termination within 4 seconds or after 30 seconds), and the determination result of the step S24 If it is determined that each retry call is included in the retry call exclusion item, it is excluded from each retry call (step S34).

Here, the monitoring and analysis of the sound quality defect performed by the client terminal 45 based on the summary information of the summary information database 40 are performed for all mobile communication switches M1 to Mn, as shown in FIG. Designate a specific mobile communication exchange in the state of comparing and retrying the retry rate, and numerically display and display the retry rate for the base station controller accommodated in the specific mobile communication exchange, and designate a specific base station controller among a plurality of base station controllers. The retry rate for is displayed numerically, and the retry rate for each route is also displayed numerically.

In the retry rate monitoring screen, when the retry rate of a specific mobile communication exchange is high, a graph of the corresponding mobile communication exchange is designated, and it is confirmed whether the retry rate of the base station controller accommodated by the specified mobile communication exchange is equally high. Next, by designating a base station controller that has a poor sound quality, it is confirmed whether the retry rate of the receiving base station is high as a whole. If both the base station controller and the base station have a high retry rate, a relay failure (outgoing broadcast) may occur. Mostly.

On the other hand, to monitor the relay line failure (intercept) on the retry rate monitoring screen, as shown in Figure 7 to select each mobile communication switch as a whole in the retry rate monitoring screen, and to arrange the retry rate in descending order in the route retry rate window If the retry rate is high in the root of the same system (for example, ITC_CGS_07), it is determined that the sound quality is poor.

In addition, when a specific route is selected by selecting a specific route in the route retry rate window, as shown in FIG. 8, a call start point and end point appear for each network device number of the corresponding route, and the destination side mobile communication exchange ( If the MSC_TER) is a particular system, it is determined that a poor sound quality occurs at the incoming line of the incoming mobile communication exchange.

In addition, when the retry rate of a specific mobile communication exchange is high on the retry rate monitoring screen, as shown in FIG. 9, a graph of the corresponding mobile communication exchange is designated to confirm whether the retry rate for the receiving base station controller is high, and then retry. If a specific base station controller having a high rate is designated and the entire receiving base station is evenly marked as having a high retry rate, it is determined to be a bad time switch of the exchange or a bad of the vocoder.

When the retry rate of a specific mobile communication exchange is high on the retry rate monitoring screen, all of the base station controllers and base stations accommodated by the mobile communication exchange have the same high retry rate. It is determined that (Space Switch) is defective.

In the case of detecting a bad base station by arranging the retry rate generation in descending order in the base station retry rate window of the retry rate monitoring screen, as shown in FIG. 10, the retry rate for each specific base station having the highest retry rate is shown in a graph form. In this case, the major increase in the retry rate is the retry rate due to the increase of call drop and the retry rate due to the poor sound quality due to the transmission path failure. By comparing CFC0) values, it is possible to distinguish whether the increase in the retry call is due to poor sound quality or call drop.

On the other hand, the present invention is not limited to the above-described typical preferred embodiments, but can be carried out in various ways without departing from the gist of the present invention, various modifications, alterations, substitutions or additions are common in the art Those who have knowledge will easily understand. If the implementation by such improvement, change, replacement or addition falls within the scope of the appended claims, the technical idea should also be regarded as belonging to the present invention.

According to the present invention as described above, by using the call data of the subscriber of the mobile communication terminal to detect the poor sound quality of the mobile communication system in real time by analyzing the retry call that is a call habit when the sound quality defect occurs, It is possible to analyze the occurrence state of the sound quality defects by communication network devices such as base stations, base station controllers, mobile communication switches, etc. by each device, terminal number, route, prefix, and the like so that the data can be objectively determined.
