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

Each embodiment according to the present invention below is only an example to aid understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention may be comprised of a combination of at least one of the individual components, individual functions, or individual steps included in each embodiment.

In particular, for convenience, alphabet letters such as '(a)' are included in some claims, but these alphabet letters do not specify the order of each step.

In addition, each signal mentioned below in each embodiment according to the present invention may mean a single signal transmitted through a single connection, etc., but may also mean a series of signal groups transmitted for the purpose of performing a specific function described later. . That is, in each embodiment, a plurality of signals transmitted at predetermined time intervals or after receiving a response signal from the other device can be expressed as one signal name for convenience.

The schematic configuration of the entire system including the communication system 100 according to an embodiment of the present invention is as shown in FIG. 1.

As shown in the figure, the entire system may be configured to include a user terminal 200 and a communication system 100 that communicates with the user communication terminal.

In this embodiment, the user terminal 200 performs wireless communication, and performs a function of generating various information related to communication quality while communicating with a base station or repeater included in the communication system 100.

In particular, the user terminal 200 is owned by subscribers to a telecommunication company, and may be a smartphone or other portable mobile communication terminal owned by general individuals.

Meanwhile, as described above, the communication system 100 communicates with the user terminal 200 to receive various information related to communication quality and performs a function of determining the communication quality status for each location.

This communication system 100 may include devices that form a direct communication channel with the user terminal 200, such as a base station or repeater, or may correspond to a specific server connected to a mobile communication network.

However, in this embodiment, it is assumed that the communication system 100 includes various devices constituting a mobile communication network as well as a base station or repeater, and each component of the communication system 100 described later may be configured in a specific server. , each component may be included in different devices that make up the overall communication system 100.

Specific functional blocks of this communication system 100 will be described with reference to FIG. 2.

As shown in the figure, the communication system 100 includes a receiving unit 110, an information registering unit 120, a valid data determining unit 130, a judging unit 140, a terminal control unit 150, and a zone setting unit 160. It may be configured to include.

The receiving unit 110 performs a function of receiving various information or signals from the user terminal 200.

In particular, the receiver 110 may perform a function of receiving a communication quality notification signal including terminal information, positioning information, and wireless signal environment information from the user terminal 200.

Here, the terminal information refers to information about the user terminal 200, and may correspond to, for example, the model number of the user terminal 200, the installed operating software version, etc.

Here, the model number of the terminal may correspond to, for example, the name or code of the terminal model given by the manufacturer, and the operating software may be an OS installed in the terminal or a specific application required for the function of this embodiment.

Positioning information is information that allows the current location of the user terminal 200 to be confirmed. For example, it may correspond to location coordinates acquired by the user terminal 200 through a Global Positioning System (GPS) satellite.

Alternatively, the positioning information may correspond to the base station ID or repeater ID acquired when the user terminal 200 forms a communication channel with the base station or repeater. In this case, the positioning information indicates the location of the user terminal 200 to the base station or repeater. This corresponds to information that allows indirect judgment based on location.

In addition, the wireless signal environment information may include information indicating the quality of the wireless signal used by the user terminal 200 when communicating with a base station or repeater, and further information related to surrounding networks that transmit wireless signals (e.g., cell ID). , Bandwidth, PCI, etc.) may also be included.

For example, information indicating the quality of a wireless signal may include Received Signal Strength Indicator (RSSI), Signal to Interference plus Noise Ratio (SINR), Reference Signal Received Power (RSRP), and Reference Signal Received Quality (RSRQ). .

In this way, the communication quality notification signal received by the receiver 110 may be transmitted according to the judgment of the user terminal 200, or may be received at the request of the receiver 110 to the user terminal 200.

For example, the user terminal 200 may periodically transmit a communication quality notification signal to the communication system 100, or may transmit a communication quality notification signal when requested from the communication system 100.

In particular, the user terminal 200 may temporarily stop transmitting the communication quality notification signal at the request or control of the communication system 100 or until a software update is performed.

This communication quality notification signal may be generated by a specific application installed on the user terminal 200, for example, a navigation application.

The information registration unit 120 performs a function of matching and registering terminal information, positioning information, and wireless signal environment information included in the communication quality notification signal received by the receiving unit 110 (i.e., matching information). In particular, when the communication quality notification signal further includes terminal information, the information registering unit 120 can match and register the terminal information, positioning information, and wireless signal environment information.

For example, the information registration unit 120 may match and register the model number of the user terminal 200 that transmitted the communication quality notification signal, the current location coordinates of the user terminal 200, and the RSSI and SINR of the wireless signal.

The zone setting unit 160 performs the function of setting a predetermined range as a geographic zone. At this time, the zone setting unit 160 can set a geographic zone based on the installation location of the base station or repeater.

For example, the zone setting unit 160 sets each individual geographic zone within a preset radius based on the installation location of base stations or repeaters managed by the telecommunication company, or divides the entire country into a grid of a predetermined size and divides each area into individual geographic zones. The grid can be set up into geographic areas.

The valid data determination unit 130 performs a function of determining valid data by comparing and analyzing matching information registered in the government register.

For example, if at least one piece of wireless signal environment information exceeds a preset range or is missing, the valid data determination unit 130 may exclude matching information including the corresponding wireless signal environment information from the valid data.

As an example, assuming that PCI, SINR, and RSRP are required to measure communication quality, the valid data determination unit 130 determines valid data when any one of them is missing in the communication quality notification signal received from the user terminal 200. Unit 130 can exclude this from valid data.

As another example, if the PCI (Physical-layer Cell ID) included in the communication quality notification signal is not a predefined number, the valid data determination unit 130 excludes the data included in the communication quality notification signal from the valid data. It can be done.

In particular, the valid data determination unit 130 may determine valid data by analyzing pre-registered matching information by geographical zone.

For example, the valid data determination unit 130 may separately extract valid data in zone A and valid data in zone B among the geographic zones. For example, a communication notification signal received from the user terminal 200 located in zone A. If the PCI included in is not the cell ID included in the corresponding area A, the matching data may be determined as invalid data.

At this time, the valid data determination unit 130 may determine the number of valid data determined for each geographical zone.

In addition, the valid data determination unit 130 may perform a communication function performance evaluation for a specific terminal model by analyzing the matching information registered in the information register 120 and determine valid data based on the performed communication function performance evaluation. there is.

Here, the communication function performance evaluation is to evaluate whether the communication function of the user terminal 200 is normal or the communication signal reception rate is good, and the valid data determination unit 130 determines the communication function of the user terminal 200 through analysis of pre-stored matching information. Performance evaluation can be performed.

For example, as a result of analyzing matching information in a specific area collected within the same time range (for example, within 1 hour) and registered in the information register 120, the user terminals 200 of the first model and the second model receive While transmitting a communication quality notification signal indicating that the signal is good, when the third model user terminal 200 transmits a communication quality notification signal indicating that the received signal is extremely poor, the valid data determination unit 130 It can be determined that the communication function performance of the user terminal 200 of model 3 is low or has a problem.

In this case, the valid data determination unit 130 may exclude matching information based on the communication quality notification signal received from the third model user terminal 200 from the valid data.

In addition, the valid data determination unit 130 analyzes the matching information registered in the information register 120, performs a communication function performance evaluation for a specific operating software version, and determines valid data based on the performed communication function performance evaluation. You can.

For example, as a result of analyzing matching information in a specific area collected within the same time range (for example, within 1 hour) and registered in the information register 120, a user terminal (200) with the first version OS and the second version OS installed ) transmits a communication quality notification signal indicating that the received signal is good, while the user terminal 200 installed with the third version OS transmits a communication quality notification signal indicating that the received signal is extremely poor, the valid data determination unit 130 may determine that the communication function performance of the user terminal 200 of the third version OS is low or has a problem.

In this case, as described above, the valid data determination unit 130 may exclude matching information based on the communication quality notification signal received from the user terminal 200 installed with the third version OS from the valid data.

The determination unit 140 performs a function of determining the communication quality state for each region based on the valid data determined by the valid data determination unit 130.

That is, since the valid data includes wireless signal environment information along with positioning information as described above, the determination unit 140 can determine wireless signal quality for each location.

When geographical areas are divided, the determination unit 140 may determine wireless signal quality for each geographical area.

In particular, the determination unit 140 may determine the communication quality status for each geographic region based on valid data after a preset time among the valid data determined by the valid data determination unit 130.

For example, the determination unit 140 can determine the communication quality status in a specific zone A based on valid data recently registered (within 24 hours) among valid data stored corresponding to a specific zone A.

The terminal control unit 150 performs a control function to stop transmission of a communication quality notification signal to a communication terminal whose communication function performance evaluation is less than or equal to a preset value based on the evaluation result of the valid data determination unit 130.

That is, as described above, the communication quality notification signal received from a communication terminal for which the communication function performance evaluation is judged to be low is not determined as valid data, so to prevent further transmission of unnecessary signals, the terminal control unit 150 sends a communication quality notification signal. This is controlled to stop the transmission of signals.

When the communication quality notification signal is made according to the active selection of the user terminal 200, the terminal control unit 150 may transmit a control message to the user terminal 200 to stop transmission of the communication quality notification signal, or the communication quality notification signal may be sent to the user terminal 200. When the signal is made at the request of the communication system 100, the terminal control unit 150 no longer requests transmission of a communication quality notification signal to the user terminal 200 of the corresponding model.

This process is similarly applied to the user terminal 200 whose communication function performance evaluation is judged to be low depending on the operating software version.

That is, the terminal control unit 150 controls the communication terminal to stop transmitting a communication quality notification signal to a communication terminal installed with a specific operating software version whose communication function performance evaluation is less than a preset value based on the evaluation result of the valid data determination unit 130. It is possible.

In this case, the terminal control unit 150 may impose a predetermined condition. For example, it may control the transmission of the communication quality notification signal to be stopped until a specific operating software version is updated.

In addition, as described above, the valid data determination unit 130 may determine the number of valid data determined for each geographical zone, and the terminal control unit 150 determines that the valid data determination unit 130 determines that the number of valid data is preset. It may also be controlled to stop transmitting a communication quality notification signal to communication terminals located in a geographical area where the value is higher than or equal to the value.

In other words, continuing to collect information in areas where a significant amount of valid data has already been accumulated to determine communication quality causes unnecessary communication traffic, so for communication terminals located in geographical areas where the number of valid data is more than the preset value, It is possible to control the transmission of communication quality notification signals to stop.

Of course, such control may be subject to certain conditions.

For example, the terminal control unit 150 may control the communication terminal located in a geographical area where the conditions are satisfied to stop transmitting the communication quality notification signal only for a preset time (for example, 1 hour), and further, in area A. If the communication terminal whose transmission of the communication quality notification signal has been stopped moves to zone B, the transmission of the communication quality notification signal may be resumed.

According to the control of the terminal control unit 150 described above, not only can the generation of unnecessary communication traffic be minimized, but also the amount of collected data can be minimized.

Hereinafter, a process in which a communication quality notification signal received by the communication system 100 according to an embodiment of the present invention is generated in the user terminal 200 will be described with reference to FIG. 3.

When a navigation app (application) is executed according to the user's selection in the user terminal 200 (step S1), a collection module is executed by the function of the corresponding navigation app (step S3), and an API for acquiring terminal wireless quality is called. (step S5).

By the API called in this way, wireless quality measurements and GPS information are matched and generated every second (step S7), and this process is repeated for a preset n seconds (step S9).

At a preset n second elapsed time, the navigation app transmits a communication quality notification signal including the information collected so far and the user's terminal information to the communication system 100 (step S11).

Although not shown in FIG. 3, when the navigation app is terminated, the functions related to wireless quality measurement in FIG. 3 are automatically terminated.

FIG. 4 shows a processing process in the communication system 100 that receives this communication quality notification signal.

Upon receiving the communication quality notification signal (step S21), the communication system 100 matches and registers the terminal information, positioning information, and wireless signal environment information (the wireless quality measurement value described above) included in the communication quality notification signal (step S23). ).

This matching information registration process continues for a preset N time.

After N time has elapsed (step S25), the communication system 100 determines valid data by analyzing the pre-registered information when compared with each other (step S27).

When determining valid data, the communication system 100 selects data that does not include at least one of the necessary elements, data received from the user terminal 200 for which the communication function performance evaluation is judged to be low, and data whose collection time is older than a preset value. Data can be excluded.

After valid data is determined, the communication system 100 can determine the communication quality status for each region (step S29).

After the communication quality status is determined in this way, the communication system 100 can provide a determination result according to a request from a user or administrator.

Meanwhile, of course, the process of performing each of the above-described embodiments can be performed by a program or application stored in a predetermined recording medium (eg, computer-readable). Here, recording media include electronic recording media such as RAM (Random Access Memory), magnetic recording media such as hard disks, and optical recording media such as CDs (Compact Disk).

At this time, the program stored in the recording medium can be executed on hardware such as a computer or smartphone to perform each of the above-described embodiments. In particular, at least one of the functional blocks of the communication system 100 according to the present invention described above may be implemented by such a program or application.
