That is, in each embodiment, a plurality of signals transmitted at predetermined time intervals or transmitted after receiving a response signal from the counterpart device may be expressed as one signal name for convenience.

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

As shown in the figure, the entire system may include a user terminal 200 and a communication system 100 communicating 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 a repeater included in the communication system 100.

In particular, the user terminal 200 is possessed by subscribers subscribing to a telecommunications company, and may be a smart phone or other portable mobile communication terminals owned by general individuals.

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

The communication system 100 may include devices that form a direct communication channel with the user terminal 200, such as a base station or a 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 a base station or a repeater as well as various devices constituting a mobile communication network, and each component of the communication system 100 described later may be configured in a specific server, , It may be included in different devices constituting the entire communication system 100 for each component.

Specific functional blocks of the 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 determining unit 140, a terminal control unit 150, and an area setting unit 160. It can be configured to include.

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

In particular, the receiving unit 110 may perform a function of receiving a communication quality notification signal including terminal information, positioning information, and radio 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, a model number of the user terminal 200, an installed operating software version, and the like.

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

The positioning information is information for determining the current location of the user terminal 200, and may correspond to location coordinates obtained by the user terminal 200 through a global positioning system (GPS) satellite, for example.

Alternatively, the positioning information may correspond to a base station ID or a repeater ID obtained when the user terminal 200 establishes a communication channel with a base station or a repeater. This corresponds to information that allows indirect determination based on location.

In addition, the wireless signal environment information may include information indicating the quality of a wireless signal used by the user terminal 200 when communicating with a base station or a repeater, and furthermore, information related to a neighboring network transmitting a wireless signal (for example, a cell ID). , Bandwidth, PCI, etc.) may also be included.

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

The communication quality notification signal received by the receiver 110 may be transmitted according to the user terminal 200's determination, or may be received by the receiver 110 upon request 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 upon request from the communication system 100.

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

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

The information registration unit 120 performs a function of matching and registering terminal information, positioning information, and radio signal environment information included in the communication quality notification signal received by the reception unit 110 (ie, matching information). In particular, when terminal information is further included in the communication quality notification signal, the information registration unit 120 may match and register terminal information, positioning information, and radio 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 location coordinates of the current user terminal 200, and the RSSI and SINR of the radio signal.

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

For example, the zone setting unit 160 sets each individual geographical zone within a predetermined radius based on the installation locations of base stations or repeaters managed by the telecommunications company, or divides the entire country into a grid having a predetermined size, and each Grids can be set to geographic areas.

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

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

For example, assuming that PCI, SINR, and RSRP are required for communication quality measurement by the valid data determining unit 130, if any one of them is missing from the communication quality notification signal received from the user terminal 200, valid data is determined. Section 130 is capable of excluding it from valid data.

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

In particular, the valid data determining unit 130 may determine valid data by analyzing pre-registered matching information for each geographical area.

For example, the valid data determination unit 130 may extract valid data of zone A and valid data of zone B of the geographical zone by distinguishing them from each other. For example, the communication notification signal received from the user terminal 200 located in zone A If the PCI included in is not a cell ID included in the corresponding area A, the corresponding matching data can be determined as invalid data.

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

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

Here, the communication function performance evaluation is to evaluate whether the communication function of the user terminal 200 is normal or whether the communication signal reception rate is good. It can perform performance evaluation.

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

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

In addition, the valid data determining unit 130 analyzes the matching information registered in the information registration unit 120 to perform communication function performance evaluation for a specific operating software version, and determines valid data based on the communication function performance evaluation performed. can

For example, as a result of analyzing matching information in a specific area collected within the same time range (eg, within 1 hour) and registered in the information registration unit 120, the user terminal 200 in which the first version OS and the second version OS are installed ) transmits a communication quality notification signal indicating that the received signal is good, whereas the user terminal 200 installed with the third version OS transmits a communication quality notification signal indicating that the received signal is not extremely good, the valid data determination unit In step 130, it can be determined that the communication function performance of the user terminal 200 of the third version OS is low or there is a problem.

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

The determination unit 140 performs a function of determining a 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 radio signal environment information along with positioning information as described above, the determination unit 140 can determine radio signal quality for each location.

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

In particular, the determination unit 140 may determine the communication quality state for each geographical area based on valid data after a predetermined point in time among the valid data determined by the valid data determining unit 130 .

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

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

That is, as described above, since the communication quality notification signal received from the communication terminal for which the communication function performance evaluation is judged to be low is not determined as valid data, the terminal control unit 150 notifies the communication quality in order to prevent transmission of any more unnecessary signals. It is to control to stop the transmission of the signal.

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 notify the communication quality. When the signal is made at the request of the communication system 100, the terminal control unit 150 no longer requests transmission of the 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 determined to be low according to the operating software version.

That is, the terminal control unit 150 controls to stop transmission of a communication quality notification signal to a communication terminal in which a specific operating software version having a communication function performance evaluation equal to or less than a predetermined value is installed based on the evaluation result of the valid data determination unit 130. It can.

In this case, the terminal control unit 150 may impose a predetermined condition. For example, it may control 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 determining unit 130 may determine the number of valid data determined for each geographical area. As a result of the determination of the valid data determining unit 130, the terminal controller 150 determines that the number of valid data is preset Transmission of the communication quality notification signal to a communication terminal located in a geographic area equal to or greater than the value may be controlled to be stopped.

That is, continuing to collect information for an area in which a significant amount of valid data has already been accumulated to determine communication quality causes unnecessary communication traffic. It is possible to control to stop transmission of the communication quality notification signal.

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

For example, the terminal control unit 150 may control the communication terminal located in the geographical area where the condition is satisfied to stop transmitting the communication quality notification signal for a predetermined time (for example, 1 hour), and furthermore, in area A When the communication terminal, in which transmission of the communication quality notification signal is stopped, moves to zone B, control may be performed so that transmission of the communication quality notification signal is resumed.

According to the above-described control of the terminal controller 150, generation of unnecessary communication traffic can be minimized as well as the amount of collected data can be minimized.

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

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

By the API called in this way, the radio quality measurement value and the GPS information are matched and generated in units of one second (step S7), and this process is repeatedly performed for a predetermined number of n seconds (step S9).

When the preset n seconds have elapsed, the navigation app transmits a communication quality notification signal including the information collected so far and its terminal information to the communication system 100 (step S11).

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

4 illustrates a process in the communication system 100 receiving such a communication quality notification signal.

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

This matching information registration process is continuously performed for a preset N time period.

After N time elapses (step S25), the communication system 100 compares and analyzes previously registered information to determine valid data (step S27).

When valid data is determined, the communication system 100 determines data that does not include at least one of the necessary elements, data received from the user terminal 200 whose communication function performance evaluation is low, and a collection time that is longer than a preset value. data can be excluded.

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

After the communication quality state is determined in this way, the communication system 100 may provide the determination result according to a request of a user or manager.

Meanwhile, it goes without saying that the process of performing each of the above-described embodiments may be performed by a program or application stored in a predetermined recording medium (for example, computer-readable). Here, the recording medium includes all of an electronic recording medium such as RAM (Random Access Memory), a magnetic recording medium such as a hard disk, and an optical recording medium such as a CD (Compact Disk).
