Description

Server, method, and computer program for managing a repeater using VOC data {SERVER, METHOD AND COMPUTER PROGRAM FOR MANAGING RELAY STATION BY USING VOICE OF CUSTOMER DATA}

The present invention relates to a server, method, and computer program for managing a repeater using VOC data.

Domestic 5G frequency bands are divided into the 3.5GHz band and the 28GHz band. Here, the 28GHz band, which corresponds to the high frequency band, has a short radio wave reach and is easily blocked by obstacles, making it difficult to use when implementing high-quality services.

Accordingly, domestic mobile carriers are providing 5G services to users through the 3.5GHz band, which is a relatively low frequency band.

Meanwhile, to provide stable 5G services, 5G network terminals are being built and operated outdoors. However, it is difficult to provide stable 5G service indoors with only signals transmitted into the building through 5G network terminals deployed outdoors, so 5G service is required to expand 5G coverage indoors so that users can smoothly use 5G service indoors. Building services are essential.

Furthermore, as more than 80% of total 5G traffic is expected to occur indoors, the configuration of a network that can provide indoor 5G high-capacity services is expected to be very important, and accordingly, indoor traffic using 5G mobile communications is expected to be very important. The demand for high-quality ultra-broadband services in the environment is expected to increase significantly.

Meanwhile, in mobile communication services, RF repeaters and optical repeaters are generally used to eliminate indoor and outdoor shadow areas.

The RF repeater consists of a service antenna and a donor antenna. The donor antenna receives the signal from the aerial line, amplifies the signal strength in the repeater, and retransmits it through the service antenna.

In the case of mobile communication services using RF repeaters, it has the advantage of being able to easily improve shadow areas without additional installation work other than power lines because it uses aerial signals from macro equipment. There is a limitation that it must be able to receive signals. Additionally, because the RF signal is amplified without digital demodulation, there is a disadvantage in that performance is limited by the quality of the macro equipment signal received locally.

To overcome these shortcomings, many 5G in-building services using optical repeaters are being implemented.

In the case of mobile communication services using optical repeaters, mobile communication signals are transmitted from the macro base station to the relevant area without signal loss using a separate standard optical cable rather than using an aerial line. Signals transmitted using optical cables are converted into RF form through ROU (Remote Optic Unit) to provide services. In the case of optical cables, signals can be transmitted without loss up to 20 km, so indoor and in-building shadow areas can be eliminated without being limited by the location of the macro base station equipment.

In this way, mobile communication service providers are burdening large expenditures on building repeaters to provide stable 5G services to users indoors.

Hereinafter, specific details for implementing the present invention will be described with reference to the attached configuration diagram or processing flow diagram.

Figure 1 is a block diagram of a repeater management server 10 according to an embodiment of the present invention.

Referring to FIG. 1, the repeater management server 10 includes a region selection unit 100, a VOC data collection unit 110, a parameter change unit 120, a repeater construction determination unit 130, and a location information derivation unit 140. And it may include an RU antenna selection unit 150. However, the repeater management server 10 shown in FIG. 2 is only one implementation example of the present invention, and various modifications are possible based on the components shown in FIG. 1.

The region selection unit 100 may select an region that requires repeater management based on population data collected for each region.

The region selection unit 100 may monitor wireless network quality based on population data collected for each region and select a region where wireless network quality deterioration has occurred among the plurality of regions.

Here, the population data includes, for example, the first population density data (gu-level population density data) and living population data provided by local governments, and the second population density data provided by the National Spatial Information Portal map service of the Ministry of Land, Infrastructure and Transport. Unit population density data) may be included.

Here, living population data refers to the total number of people existing in a specific area and at a specific time (for example, the time of a preset time unit) estimated by local governments and telecommunications companies using public big data and telecommunication data.

Living population data includes, for example, the population provided with services through the telecommunication base station of a telecommunication company covering a specific area (e.g., the population who temporarily visits a specific area for work, tourism, medical care, education, shopping, etc., causing administrative demand). ) refers to the estimated population based on

For example, the region selection unit 100 selects a district-level region with a population density higher than the preset first threshold as the primary candidate based on population density data provided by the local government of each region, and the national government of the Ministry of Land, Infrastructure and Transport Using the information provided by the spatial information portal map service, the district-level area with a population density higher than the preset second threshold among the primary candidate areas (district-level areas) can be selected as the secondary candidate area.

Lastly, the region selection unit 100 can use living population data provided by local governments to classify regions that require repeater management and regions that do not need management among secondary candidate regions.

For example, referring to FIG. 2A, the region selection unit 100 selects a region that satisfies condition 1 (population density data >= first threshold) among a plurality of regions based on population density data provided by the local government of each region. The area can be classified as a 'high population density administrative ward', and the area that does not satisfy condition 1 can be classified as a 'low population density administrative ward'.

The region selection unit 100 selects regions that satisfy condition 2 (living population data >= second threshold) among multiple regions as 'high living population density administrative districts' based on living population data provided by local governments in each region. Areas that do not satisfy condition 2 can be classified as ‘low-living population administrative districts’.

For example, referring to Figures 2a and 2b together, the region selection unit 100 can select the first region, which is both a 'high population density administrative ward' and a 'high population density administrative ward', as an area requiring repeater management. there is. High population density data can be interpreted as a residential area, and high living population data can be interpreted as a commercial area/company dense area/university area, etc., so the first area can be classified as a residential area and a commercial area category. . Candidate buildings for repeater management (construction) in the first region may include, for example, apartments, high-rise buildings, and supermarkets.

The region selection unit 100 may select the second region, which is a 'high population density administrative ward' but also a 'low population density administrative ward', as an area requiring repeater management. Here, the second area may be classified into a residential area category, and building candidate sites for repeater management (construction) within the second area may include, for example, apartments. For example, as shown in Figure 2c, the Bangbae-dong area may correspond to the second area.

The region selection unit 100 may select the third region, which is both a 'low population density administrative ward' and a 'high population density administrative ward', as an area requiring repeater management. Here, the third area can be classified into commercial areas, company-dense areas, and university districts, and building candidate sites for repeater management (construction) within the third area may include, for example, high-rise buildings, supermarkets, and university buildings. there is.

The region selection unit 100 may classify the fourth region, which is both a 'low population density administrative ward' and a 'high population density administrative ward', as an area where repeater management is unnecessary.

The VOC data collection unit 110 can collect a plurality of VOC data generated in an area selected as an area requiring repeater management. Here, the plurality of VOC data may be request messages for improving communication quality for voice call services or data services. Both voice call services and data services are services that are significantly affected by reception sensitivity.

Meanwhile, when an area requiring repeater management is selected, a process of selecting an RU antenna in operation for the purpose of serving the repeater is necessary.

To this end, the VOC data collection unit 110 may further collect location information on each of a plurality of user terminals that transmitted VOC data in an area selected as an area requiring repeater management.

The location information deriving unit 140 may derive location information of a building in which the quality of voice call service or data service needs to be improved based on the location information of each of the plurality of user terminals.

For example, referring to FIG. 2D, the RU antenna selection unit 150 selects a plurality of RU antennas (210) located within a preset radius from a building 200 that needs to improve the quality of voice call service or data service in an area requiring repeater management. -1 to 210-6) can be selected. Subsequently, the RU antenna selection unit 150 analyzes the antenna aiming direction of each of the plurality of RU antennas 210-1 to 210-6 and the plurality of RU antennas 210-1 to 210-6 and the building 200. ) One RU antenna (210-2) can be selected from among the plurality of RU antennas (210-1 to 210-6) based on a comparison of the distance between them.

In general, the service coverage of the RU antenna is based on a service coverage angle of approximately ±60° based on the RU antenna's antenna aiming direction.

Considering this, the RU antenna selection unit 150 selects a plurality of RU antennas 210-1 to 210-6 based on whether the building 200 is included in the service coverage corresponding to the azimuth ±60° value of the RU antenna. ), one RU antenna (210-2) that provides data services to a plurality of user terminals located in the building 200 can be selected.

The parameter change unit 120 may change the parameters of a repeater or RU antenna installed in the area based on the types of plural VOC data collected in the area selected as an area requiring repeater management. For example, referring to FIGS. 2D and 2E together, the parameter change unit 120 may change the mechanical parameters for the selected RU antenna 210-2. In addition, the parameter change unit 120 is configured for the RU antenna (210-2) in the direction facing the RU antenna (210-2) from the repeater 300 installed in the building 200, as shown in (a) and (b). You can change the M-azimuth parameter and change the M-tilt parameter for the RU antenna 210-2 using the height of the building 200 and the height of other buildings 310 where the RU antenna 210-2 is installed. there is.

Meanwhile, compared to data services, voice call services are periodically allocated fixed resources and are relatively less affected by reception sensitivity. In addition, considering the currently established communication infrastructure, there are almost no areas where voice call service is not available or disconnected, although data service speeds may be slow. Therefore, in the case of voice call-related VOC data, the quality of voice call service can be improved by remotely adjusting the electrical parameters of the RU antenna in the area where the voice call-related VOC data is received.

Specifically, when the plurality of collected VOC data is voice call-related VOC data, the RU antenna selection unit 150 selects a plurality of user terminals located in the building among the plurality of RU antennas located within a preset radius from the derived location information of the building. You can select an RU antenna that provides voice call service.

The parameter change unit 120 may change the electrical parameters for the RU antenna selected by the RU antenna selection unit 150. Here, the electrical parameters may include at least one of a power parameter of the RU antenna, a beam pattern parameter derived based on the directionality of the building, an E-azimuth parameter, and an E-slope parameter.

For example, the parameter change unit 120 increases the power of the selected RU antenna or changes the beam pattern parameter, E-azimuth parameter, and E-slope parameter in consideration of the direction of the building where voice call-related VOC data occurred. By doing this, the quality of voice call service can be improved.

Meanwhile, from the user's perspective, the reception sensitivity of data services is greatly affected, so in order to provide uninterrupted data services, emphasis must be placed on link stability.

To this end, when the plurality of collected VOC data is data service-related VOC data, the parameter change unit 120 sends a message requesting a change in mechanical parameters for the repeater corresponding to the derived location information of the building to the repeater management terminal. Can be transmitted. Here, the mechanical parameters may include an M-azimuth parameter (antenna azimuth) and an M-tilt parameter (antenna tilt) derived based on the orientation of the building.

The manager of the repeater management terminal that has received the message requesting change of mechanical parameters for the repeater can visit the area where the corresponding repeater is installed and change the mechanical parameters of the RU antenna. The manager of the repeater management terminal can change the azimuth and tilt of the repeater in the direction of the building where data service-related VOC data occurred. Through this, the quality of data services can be improved.

The repeater construction decision unit 130 may determine an area in which to build a new repeater based on the total number of collected VOC data (the total number of voice call-related VOC data and the number of service-related VOC data).

If the total number of VOC data collected is greater than or equal to a preset threshold, the repeater construction decision unit 130 may decide to build a new repeater in the building.

The repeater construction decision unit 130 may transmit a message requesting construction of a new repeater to the building to the repeater management terminal.

Meanwhile, those skilled in the art will recognize the region selection unit 100, the VOC data collection unit 110, the parameter change unit 120, the repeater construction determination unit 130, the location information derivation unit 140, and the RU antenna selection unit 150. It will be fully understood that each may be implemented separately, or one or more of them may be implemented integratedly.

Figure 4 is a flowchart showing a method of managing a repeater using VOC data according to an embodiment of the present invention.

Referring to FIG. 4, in step S401, the repeater management server 10 may select an area requiring repeater management based on population data collected for each region.

In step S403, the repeater management server 10 can collect a plurality of VOC data generated in the selected area.

In step S405, the repeater management server 10 may change the parameters of a repeater or RU antenna installed in the selected area based on the types of the plurality of collected VOC data.

In step S407, the repeater management server 10 may determine an area in which to build a new repeater based on the total number of collected VOC data.
