[0002] Small cell base stations are installed in dead zones to provide increased capacity, guarantee high-capacity data transmission, and support multiple connectivity, enabling the creation of various convergence services in urban areas, hotspots, and densely populated areas such as schools, airports, stadiums, and hospitals.

[0003] In particular, as ultra-high speed, ultra-low latency, and ultra-connectivity become possible in the era of 5th generation (5G) mobile communication, various services utilizing the advantages of 5G communication are being prepared in places close to daily life, and to this end, many small cells are scheduled to be installed and operated in close proximity to users.

[0004] Meanwhile, according to conventional technology regarding the operation of small cell base stations, in order to check the operational status of a small cell base station, operational information and function manipulation for each small cell were performed using an operation management system installed at a central location for multiple small cells, and the operator could access and control operational information by selecting a specific small cell after undergoing secure authentication. However, when an operator wanted to specify one small cell among many and view operational information in real time on-site, it was practically impossible to control the operation of the small cell base station by accessing its information at the site where it was installed, because accessing the remote operation management system was complex or difficult.

In order to facilitate an overall understanding of the present invention, the same reference numerals are used for identical components in the drawings, and redundant descriptions of identical components are omitted.

[0049] FIG. 1 is a conceptual diagram illustrating the principles of augmented reality-based base station operation and configuration control according to an embodiment of the present invention.

[0050] Figure 1 shows an example of a service in which an operation screen for a small cell is displayed on the user's AR glasses (20) when a user wearing augmented reality (AR) glasses as presented in this embodiment approaches a small cell base station (hereinafter also briefly referred to as a small cell) and recognizes the small cell.

[0051] The small cell base station (50) includes LTE (long-term evolution) or 5th generation (5G) base stations and base stations to be derived in the future, and is not limited to small cells but may also include other communication devices that perform the same or similar functions as small cells. An Open Application Programming Interface (60) is established within the small cell and provides information about the small cell base station (50) to external application service servers (30) through the API. The application service server (30) can provide an AR operation screen to the user through AR glasses (20) by utilizing the information provided through the Open API (60) within the small cell base station (50).

[0052] The AR operation screen may include various base station operation information (21 to 28) for a small cell base station (50). The base station operation information may include radio resource management (RRM) information, call control (CC) information, performance information, base station configuration information, or a combination thereof.

[0053] AR glasses (20) can be configured to have an AR mobile application and a sub-communication system for LTE or 5G communication, and to be directly connected to an application service server (30) so as to display an AR operation screen on the AR glasses screen or select a specific operation menu on the AR operation screen and adjust the state or configuration of the selected menu.

[0054] Additionally, the AR glasses (20) can be connected to a user terminal (10) equipped with a sub-communication system and an AR mobile application, and can be configured to be connected to an application service server (30) through the user terminal (10) to display an AR operation screen or to select a specific operation menu on the AR operation screen and adjust the state or configuration of the selected menu.

[0055] FIG. 2 is a conceptual diagram illustrating the process of recognizing small cell base stations installed in different locations through AR glasses in the installation area in relation to a base station operation method according to one embodiment of the present invention.

[0056] Referring to FIG. 2, users (11, 12) located in different places can recognize a small cell base station (50a, 50b) located near their current location while wearing AR glasses (20a, 20b). For example, recognition of the small cell base station (50a, 50b) can be performed by recognizing a marker located on or around the housing of the small cell base station equipment or by recognizing a 3D object through the camera of the AR glasses (20a, 20b).

[0057] In the case of markers, they can be attached to the outer surface of the small cell in the form of an image or a QR (quick response) code. Of course, AR glasses (20a, 20b) can be configured to detect a face by utilizing feature points within the image data without using markers, and thereby directly identify the image.

[0058] Recognizing a 3D object can refer to detecting the shape of an object as the camera's viewpoint moves and recognizing a small cell base station corresponding to the 3D object using artificial intelligence methods such as computer vision or machine learning. In addition, in the recognition of a 3D object, the object can be configured to finely identify the object, i.e., the small cell base station, by utilizing the object's location information along with the object information recognized in 3D.

[0059] The aforementioned AR glasses (20a, 20b) can be used independently or connected to a user terminal (10a, 10b) such as a smartphone, and additional information regarding an object recognized through a camera mounted on the AR glasses (20a, 20b) can be processed and displayed on the AR glasses screen. Additionally, the AR glasses (20a, 20b) can be configured to allow selection and input via hand tracking. By utilizing the functions of these AR glasses (20a, 20b), augmented information regarding an object placed within the field of view at the current location can be displayed and manipulated in real time, and accessibility to object information can be improved from closed information to open information by linking with an Open API.

[0060] To implement augmented reality technology in AR glasses (20a, 20b), a dedicated platform that is convenient for implementation can be used. As a dedicated platform, Vuforia, ARkit, Wikitude, etc., can be used in addition to Google’s ARcore. In addition, the languages ​​used in AR glasses (20a, 20b) can be Java, the open graphics library (openGL), and the global game engine Unity3D.

[0061] Additionally, users (11, 12) located in different places can display an AR operation screen containing base station status information and base station information for a small cell base station (50a, 50b) on the AR glasses screen while wearing AR glasses (20a, 20b), and change or control the operation status by motion tracking or pointing at specific operation information on the AR operation screen.

[0062] Motion tracking can utilize data from an inertial measurement unit (IMU) or a sensor performing a corresponding function to recognize the position and direction according to the movement of the camera, and thereby enable the identification of objects within the captured video.

[0063] FIG. 3 is a conceptual diagram showing a base station operation device that can be employed for augmented reality-based base station operation and configuration control of FIG. 1.

[0064] Referring to FIG. 3, the base station operating device may include one or more of an application service server (30) and a small cell base station (50). In this embodiment, a service provision structure is shown comprising an AR mobile app connected to AR glasses, an application service server (30) connected to the AR mobile app, and a small cell base station (50).

[0065] The AR mobile app can be used when the AR glasses are connected to a user terminal. The AR mobile app can be installed to provide computing and communication functions on the AR glasses themselves, in which case the AR mobile app can be connected to an application service server (30) using an AR application running inside the AR glasses.

[0066] The application service server (30) is equipped with application service logic (32) and an open API call unit (34), and can be equipped with a small cell base station recognition function, etc., and can be equipped with an open API call and information provision function required for the application service.

[0067] The application service logic (32) receives base station-related information from a communication node and can recognize a specific base station based on the base station-related information. The application service logic (32) can periodically or intermittently receive base station collection information for a specific base station from an open application programming interface (API) agent of a specific base station, and can be configured to transmit base station collection information of a specific base station corresponding to the recognition of a specific base station to a communication node.

[0068] Additionally, the application service logic (32) may receive a request message for changing base station information for a specific base station from a communication node, and in response to the request message for changing base station information, request a change in base station information to the open API server of the previously recognized specific base station. The application service logic (32) may also be configured to receive a result of changing base station information corresponding to the request for changing base station information from the open API server, and to transmit the received result of changing base station information to the communication node.

[0069] Additionally, the application service logic (32) may be configured to request base station collection information from the open API server of the base station based on the recognition of a specific base station, and to receive base station collection information including base station status information and base station operation information from the open API server.

[0070] Additionally, the application service logic (32) may be configured to transmit a request for collecting base station status information or event subscription information for registering event collection to the open API server of the specific base station according to the recognition of the specific base station.

[0071] Additionally, the application service logic (32) may be configured to request user authentication for a communication node connected via a network, and to request augmented reality-based recognition information for a specific base station from the communication node that is authenticated based on the user authentication input according to the request for user authentication. Generating augmented reality-based recognition information at the communication node may include obtaining relevant information about a small cell base station from an image captured through the camera of the communication node in an AR mobile application installed on the communication node, such as AR glasses or a user terminal.

[0072] The open API call unit (34) is connected to the application service logic (32) and can be connected to the open API server (60) and open API agent (70) of the small cell base station (50) under the control of the application service logic (32).

[0073] That is, the open API call unit (34) can be connected to an open API server (60) based on HTTP (hypertext transfer protocol) with a first URL call (a first URL call, S1) and a second URL call (a second URL call, S2) having information representing resources as URLs. The first URL call (S1) may include a method for retrieving information (GET), a method for modifying information (PUT), a method for registering information (POST), and a method for deleting information (DELETE), and the second URL call (S2) may include a method for requesting notification when an event occurs in the future through service subscription or event registration (SUBSCRIPTION). The method refers to an HTTP method.

[0074] Additionally, the open API call unit (34) may receive a third URL call (S3) from the open API agent (70). The third URL call (S3) may include a method (NOTIFY) that notifies the subscriber, i.e., the application service server (30), of event-related information when an event corresponding to registration or subscription occurs. The event-related information may include base station collected information, and the base station collected information may include base station status information based on changes in the state of the base station, base station operation information, base station unique information, etc.

[0075] A small cell base station (50) operates based on a base station protocol stack (80), and an HTTP (hypertext transfer protocol) based open API server (60) is run to disclose base station operation information, and an open API agent (70) is installed to disclose base station operation information and can provide base station operation information to the outside through interaction with the base station protocol stack (80). The open API server (60) may be briefly referred to as an open API.

[0076] The base station protocol stack (80) includes at least some software for base station operation and may include means for a physical layer (PHY), medium access control (MAC), radio link control (RLC), scheduler, packet data convergence control (PDCP), service data adaptation protocol (SDAP), radio resource control (RRC), and radio resource management (RRM), or components that perform functions corresponding to such means.

[0077] The physical layer (PHY) can be a layer 1 of the base station protocol stack (80) and may have a PHY convergence form. The physical layer (PHY) carries all signals transmitted and received to and from the MAC transmission channel through the public interface. It can be responsible for functions such as adaptive modulation and coding (AMC) of the corresponding link for the RRC layer, power control, cell search for initial synchronization and handover, and other measurements required within and between the LTE system.

[0078] Media Access Control (MAC), Wireless Link Control (RLC), and Packet Data Convergence Control (PDCP) can form layer 2 of the base station protocol stack (80).

[0079] Media Access Control (MAC) is a MAC layer responsible for mapping between logical channels and transport channels, multiplexing of service data units (MAC SDUs) into transport blocks (TBs) transmitted from other logical channels to the physical layer on the transport channel, reporting of multiplexing scheduling information for MAC SDUs from other logical devices, error correction through hybrid automatic repeat and request (HARQ), priority processing between user terminals by dynamic scheduling, priority processing between logical channels of a single user terminal, and logical channel prioritization.

[0080] Radio Link Control (RLC) can operate in three modes: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). The RLC layer can be responsible for the transmission of upper-layer protocol data units (PDUs), error correction via ARQ dedicated to AM data transmission, concatenation of RLC SDUs, and error correction via segmentation and reconfiguration for UM and AM data transmission.

[0081] The scheduler is connected to the MAC and RLC layers and can guarantee QoS, maximize transmission volume, or perform scheduling using event information collected according to event collection registration.

[0082] The Packet Data Convergence Control (PDCP) layer can be responsible for compressing and decompressing the header of Internet Protocol (IP) data, transmitting data in the user plane or control plane, maintaining the PDCP sequence number (SN), sequentially delivering upper layer PDUs during lower layer reconfiguration, deduplication of lower layer SDUs during lower layer reconfiguration for data radio bearers (DRBs) mapped to replicated RLC AM data, encrypting and decrypting user plane data and control plane data, and protecting and verifying the integrity of control plane data.

[0083] Service Data Adaptation Protocol (SDAP), Radio Resource Control (RRC), and Radio Resource Management (RRM) can form layer 3 of the base station protocol stack (80).

[0084] The Service Data Adaptation Protocol (SDAP) layer comprises an SDAP sublayer, and the SDAP sublayer is configured for DRBs (hereinafter abbreviated as DRB) by the RRC and can map quality of service (QoS) flows to DRBs. One or more QoS flows may be mapped to a single DRB. Additionally, the SDAP sublayer can map PC5 QoS flows to SL-DRBs according to mapping rules determined in relation to carrying SL-DRB packets of PC5 QoS flows in new radio (NR) sidelink (SL) communication. One or more PC5 QoS flows may be mapped to a single SL-DRB. A single PC5 QoS flow may be mapped to only one SL-DRB at a time in the NR sidelink for transmission.

[0085] Additionally, SDAP entities may be located in the SDAP sublayer. Multiple SDAP entities may be defined for a single user terminal. In the case of an NR sidelink, SDAP entities can be configured at the user terminal according to the ID (identification) and cast type of Destination Layer 2. These SDAP entities can receive and forward SDAP SDUs from the upper layer and forward and receive SDAP data PDUs to and from peer SDAP entities through the lower layer. At this time, when an SDAP entity on the sending side receives an SDAP SDU from the upper layer, the SDAP entity can construct the corresponding SDAP data PDU and forward it to the lower layer. And, when an SDAP entity on the receiving side receives an SDAP data PDU from the lower layer, the SDAP entity can retrieve the corresponding SDAP SDU and forward it to the upper layer.

[0086] Radio Resource Control (RRC) includes an RRC sublayer. The main services and functions of the RRC sublayer may include broadcasting system information related to the non-access stratum (NAS) used to exchange non-radio signaling between the core network (CN) and the user terminal, broadcasting system information related to the access stratum (AS), paging, configuration, maintenance, and release of RRC connections between a wireless interface such as an E-UTRAN (evolved universal terrestrial radio access network) and the user terminal, and security functions including key management, configuration, setup, maintenance, and release of end-to-end radio bearers.

[0087] Wireless resource management (RRM) may take the form of an application and may be configured to efficiently dynamically allocate limited wireless resources when wireless channel characteristics, such as the physical layer, are not constant over time and change frequently. The RRM application may periodically collect base station status information or collect base station event information in response to a request for base station status information collection or registration of event collection. Such base station status information or base station event information may be transmitted to an open API agent (70) as base station collected information.

[0088] Figure 4 is a conceptual diagram showing the structure of an Open API Agent that can be adopted in the base station operating device of Figure 3.

[0089] Referring to FIG. 4, the open API agent (70) is equipped with a structure for providing information within the small cell base station to the open API server by linking with the open API server within the small cell base station. That is, the open API agent (70) may be equipped with a subscription management unit (72), a data management unit (74), an event management unit (76), and an interface matching unit (78) for information transmission and information management according to API characteristics between the HTTP-based open API server and the base station protocol stack.

[0090] The subscription management unit (72) performs information transmission and information management according to API characteristics between the open API server and the base station protocol stack. That is, when there is a periodic request for collection of base station information, the subscription management unit (72) executes subscription content management and periodic data collection and can send the collected information to the address of the user's communication node, e.g., the request address.

[0091] The data management unit (74) manages data transmitted from the base station protocol stack, and in the case of specific information, it can query the data managed by the data management unit and send it to an open API server, an application service server, or a communication node. The data managed by the data management unit (74) includes data obtained through periodic information collection.

[0092] For example, the data management unit (74) receives a base station collection information request message from an open API server, and in response to the base station collection information request message, requests base station collection information from the base station protocol stack or searches for base station collection information stored in advance, and transmits the base station collection information stored in advance to the open API server.

[0093] The event management unit (76) has a management function for receiving notifications regarding the occurrence of events that can be utilized for services within the small cell base station.

[0094] The interface matching unit (78) is composed of a function that links with an open API server and a function that links with a base station protocol stack, and may use a socket interface and an internal communication method. For example, the interface matching unit (78) receives a base station information change request message from an open API server, generates a base station control management signal to change the corresponding state or configuration of the base station according to the base station information change request message, and transmits the result of the base station information change based on the base station control management signal to an open API server or an application service server.

[0095] Figure 5 is a flowchart illustrating the operating principle of an AR mobile application that can be employed in the operation and configuration control of an augmented reality-based base station of Figure 1.

[0096] Referring to FIG. 5, an AR mobile app that operates in connection with AR glasses can be run on the AR glasses or on a device connected to the AR glasses. The device connected to the AR glasses may include a user terminal.

[0097] When the AR mobile app is launched, the AR mobile app first connects to the application service server (S501).

[0098] Next, if the AR mobile app is determined to be an authenticated user through the user authentication procedure from the application service server, the AR mobile app can continue to use the base station operation service (S502). If the user authentication procedure is not passed by the AR mobile app, the application service server may return to the beginning and wait for the same or a different AR mobile app to connect to the application service server.

[0099] As a user authentication method that can be employed in the aforementioned user authentication procedure, for example, a user authentication interface of an application service server that allows access only to secure users may be utilized. The user authentication interface may be equipped with a login input field and a password input field. In this case, the user can use the base station operation service by entering an ID and password into the user authentication interface displayed on the screen of the AR mobile app and receiving user authentication from the application service server. Of course, in addition to the method using login and password, the user authentication interface may use one or a combination of various existing authentication methods, such as user biometric authentication or phone number authentication.

[0100] Next, the AR mobile app may guide the user to photograph a small cell base station, which is the target of the base station operation service, at the current location using the camera of the AR glasses. In this case, a camera image may be displayed on the screen of the AR glasses in which the small cell base station, captured by the camera of the user terminal, is included as an object within the image (S503).

[0101] Next, the AR mobile app can detect or recognize a small cell base station or the equipment to be recognized within the camera image displayed on the screen of the AR glasses or within the camera's field of view (S504).

[0102] Small cell base stations can be identified using QR (quick response) codes, markers, etc., or by recognizing 3D camera images using artificial intelligence or machine learning methods, or by adding location information to identify a specific small cell. The process of recognizing or identifying small cell base stations may be performed by an AR mobile app, an application service server, or a third-party server, and may be repeated without limitation or performed repeatedly for a predetermined number of times. The AR mobile app can transmit the identified small cell base station information to the application service server.

[0103] At this time, the application service server can request base station information from the corresponding base station using an open API call unit based on the small cell base station information received from the AR mobile app, and transmit the information obtained from the corresponding base station to the AR mobile app in accordance with the request for base station information.

[0104] The AR mobile app receives status information of a small cell base station from an application service server (S505) and can display the received base station status information on the screen of the AR glasses (S506). The base station status information may include base station operation information. The base station operation information may consist of information that is one-time information or information that is periodically collected and displayed.

[0105] For example, base station operation information may include Radio Resource Management (RRM) information, Call Control (CC) information, performance information, base station configuration information, or a combination thereof.

[0106] Meanwhile, if the user wants to change the base station configuration information (S507), the AR mobile app can send a base station information change request message containing base station change information corresponding to the user's selected input to the application service server (S508).

[0107] User selection input may include using hand tracking or pointing functions to designate or change the configuration information for a base station configuration that requires a change in status or information on the screen of AR glasses where the status or operation information of a specific small cell base station is displayed.

[0108] Such base station change requests are transmitted to the corresponding small cell base station via an open API server through an application service server, and the processing result is transmitted from the small cell base station to the application service server via the open API server, and also transmitted to an AR mobile app via the application service server, after which it can be displayed on the screen of the AR glasses.

[0109] Meanwhile, the AR mobile app may be configured to terminate the current base station operation service process after transmitting a base station information change request message to the application service server without receiving a response or change result. Additionally, the AR mobile app may terminate the current process for the base station operation service and return to the stage of receiving base station status information for a certain period of time after receiving a response or change result to the base station information change request message. In particular, the AR mobile app may terminate the current base station operation process if the user desires, or if a certain period of time or certain conditions are satisfied (S509).

[0110] Figure 6 is a flowchart of the overall AR operation processing procedure that can be employed in the augmented reality-based base station operation and configuration control of Figure 1.

[0111] In FIG. 6, the application service AR mobile app (25) refers to an augmented reality (AR) mobile application for application services regarding base station operation and configuration control. The AR mobile app (25) may be installed on a user terminal (10) or on AR glasses. The user terminal (10) or AR glasses may be equipped with a communication subsystem capable of exchanging signals and information with an application service server (30) via a network. In this case, the user terminal (10) or AR glasses may be referred to as a communication node.

[0112] And, the small cell base station (50) is equipped with an open API server (60), an open API agent (70), and base station software (software, SW, 80a). The open API server (60) may be referred to as a base station open API server, the open API agent (70) as a base station open API agent, and the base station SW (80a) as a base station protocol stack or base station protocol stack software.

[0113] Referring to FIG. 6, when an AR mobile app is executed on an AR glass or a user terminal (10) connected to the AR glass, the AR mobile app (25) first connects to an application service server (S601). This connection attempt can be performed repeatedly within a preset number of times or a period range.

[0114] The application service server (30) may request user authentication from the AR mobile app (25) accessing for network connection (S602). The user authentication request may be performed by the application service server (30) providing a user authentication interface to the AR mobile app (25).

[0115] The AR mobile app (25) transmits user authentication information, which is entered according to the user authentication event occurring in the user authentication interface, that is, the input of user authentication information, to the application service server (30) (S603).

[0116] When the user authentication information is correct and valid, the application service server (30) sends a message for base station recognition request to the AR mobile app (25) (S604). In response to this base station recognition request message, the AR mobile app (25) activates the camera of the user terminal (10) or AR glasses to recognize the small cell base station or the equipment and sends the recognition result to the application service server (30) (S605).

[0117] At this time, the user can move the camera's field of view toward the small cell base station or the corresponding equipment so that the base station or equipment is located within the camera image. The camera image captured by the camera or the small cell base station identification information recognized in the camera image can be transmitted in real time to the application service server (30).

[0118] The application service server (30) can select a specific small cell base station among the objects in the camera image or determine a specific base station from the small cell base station identification information (S606).

[0119] The application service server (30) can extract actual base station connection information from the identified small cell base station information and, in order to obtain base station operation status information, use the URL address of the open API of the base station to proceed with a registration procedure or a subscription procedure for monitoring the base station operation status (S607 to S611).

[0120] The registration or subscription procedure may include steps (S607, S608) in which the application service server (30) transmits a subscription request message for a service that provides base station status information or event information to an open API server (60), and the open API server (60) transmits the subscription request message to an open API agent (70).

[0121] That is, the subscription information included in the subscription request message can be transmitted from the application server server (30) to the base station’s open API server (60) via a URL address, and then transmitted from the open API server (60) to the base station’s open API agent (70) via a socket or internal communication method.

[0122] Additionally, the registration procedure or subscription procedure may further include a step (S609) in which an open API agent (70) requests the collection of base station status information or event information for a small cell base station specified by a subscription request message according to a subscription request message, or transmits a message to a base station SW (80a) to register a collection function.

[0123] Additionally, the open API agent (70) may further include steps (S610, S611) of responding to a sign-up request message and sending a sign-up response message regarding registration completion or sign-up completion to an open API server (60), and the open API server sending the sign-up response message to an application service server (30).

[0124] The base station SW (80a) can periodically collect base station status information and base station event information based on subscriber information (S612). The base station status information and base station event information are included in the base station information and can be referred to as base station collected information or simply base station information, respectively.

[0125] Access to the open API server (60) within the small cell base station via a URL call from the aforementioned application service server (30) may be subject to prior security authentication. Furthermore, the response to the subscription request URL call may be performed through another URL call for a subscription confirmation notification (see S610, S611). Additionally, the information collected in response to the subscription request may be periodic performance information or event information occurring at the base station. This information collection function may be performed by the base station SW (80a) (see S612).

[0126] Additionally, the aforementioned subscription information may be directly transmitted to and processed by the base station protocol stack depending on the implementation. That is, the subscription information may be collected by the base station SW (80a) including the base station protocol stack and managed by the open API agent (70). The subscription information may include various information to be displayed on the operation screen of the AR glasses.

[0127] Next, when base station information is collected from the base station SW (80a), the open API agent (70) may request base station information from the base station SW (80a) at specific time intervals or receive the collected base station information from the base station SW (80a) at specific time intervals (S613). That is, the base station information collected from the base station SW (80a) may be transmitted to the open API agent (70) or stored in the base station's storage device or database. In this case, the open API agent (70) may be installed to be connected to and accessible from the base station's storage device or database.

[0128] Next, the open API agent (70) can transmit base station collection information directly to the application service server (30) without going through the open API server (60) (S614). At this time, the open API agent (70) can use the URL information of the application service server (30) transmitted through the open API server (60).

[0129] The application service server (30) can transmit base station collection information received from the open API agent (70) to the AR mobile app (S615). Here, the application service server (30) may be configured to store and manage the base station collection information received periodically from the open API agent (70), or to generate information to be displayed on the AR operation screen of the AR mobile app based on the base station collection information received from the open API agent (70), and to transmit the generated information, that is, AR operation screen information processed from the base station collection information, to the AR mobile app.

[0130] The AR mobile app can configure an AP operation screen to be displayed on the AR glasses based on base station collection information or AR operation screen information received from the application service server (30) and display it on the screen of the AR glasses (S616).

[0131] Meanwhile, in the configuration of the AR operation screen, base station basic information, such as small cell base station configuration information, which is not non-periodical or event-based base station status information or event information, can be configured to be requested from the application service server (30) to the open API server (60) via a URL call (S617).

[0132] The aforementioned URL call may include a first URL call (S1) and a second URL call (S2) having information representing a resource as a URL. The first URL call (S1) may include a method for retrieving information (GET), a method for modifying information (PUT), a method for registering information (POST), and a method for deleting information (DELETE), and the second URL call (S2) may include a method for requesting notification when an event occurs in the future through service subscription or event registration (SUBSCRIPTION).

[0133] These URL call-based requests are transmitted via an open API agent (70) and a base station SW (80a) within the base station (S618, S619), and after being used to configure the information in each component, they can be transmitted to an application service server (30) via the base station SW (80) and the open API agent (70) as a response message (S620, S621, S622). The base station collected information or base station information transmitted to the application service server (30) can be processed into a form that can be received and processed by the AR mobile app (25) and transmitted from the application service server (30) to the AR mobile app (25) (S623). Upon receiving this, the AR mobile app (25) can display AR operation information including the base station information or base station collected information on the screen of the AR glasses (S624).

[0134] Meanwhile, if a user wants to change specific base station configuration information based on AR operation information displayed on the AR glasses screen, the AR mobile app (25) can receive input of the specific base station information that the user wants to change by utilizing hand tracking or pointing methods supported by the AR glasses and transmit a base station information change request message including the base station information to the application service server (30) (S625).

[0135] A request for base station information change can be transmitted from the application service server (30) to the base station SW (80a) via the open API server (60) and the open API agent (70) (S626 to S628).

[0136] The result of the requested base station information change is transmitted again from the base station SW (80a) to the application service server (30) via the open API agent (70) and the open API server (60) (S629 to S631), and can be transmitted from the application service server (30) to the AR mobile app (25) (S632). The information regarding the result of the base station information change can be reflected in the AR operation information and displayed on the AR operation screen of the AR glasses (S633).

[0137] According to the present embodiment, a user or operator can check the current operational status of a small cell base station or base station equipment or monitor it for a predetermined period of time through AR glasses at the site where the small cell base station or base station equipment is installed, and furthermore, can change the configuration of the small cell device and immediately check the results of the change. In addition, there is an advantage in that, for base station equipment installed externally, changes in the status resulting from the configuration change can be directly checked in real-time at the site. For example, the angle adjustment of the base station antenna can be performed through the operation screen displayed on the AR glasses, and the resulting changes in coverage and performance can be checked immediately at the site. This can contribute to providing services for AR-based operation and configuration control based on the characteristics of other equipment as well.

[0138] Furthermore, by disclosing information on small cell base stations and base station equipment based on open APIs, it can be utilized not only for AR operation management but also in various application services. Moreover, by utilizing application service servers connected via URL calls to open API servers and agents for AR operation management, diverse service environments targeting various small cell base stations and base station equipment can be effectively provided simply by changing the open API URL.

[0148] Additionally, the communication node (100) may support MIMO transmission (e.g., SU (single user)-MIMO, MU (multi user)-MIMO, massive MIMO, etc.), CoMP (coordinated multipoint) transmission, carrier aggregation (CA) transmission, transmission in an unlicensed band, device-to-device communication (D2D) (or ProSe (proximity services)), IoT (Internet of Things) communication, dual connectivity (DC), etc. Here, the user terminal may perform operations corresponding to the communication node (100), which is a base station, and operations supported by the communication node (100). For example, the communication node (100) may transmit and receive signals to and from the user terminal based on the SU-MIMO method or the MU-MIMO method. Additionally, the communication node (100) can transmit a signal to a user terminal based on the CoMP method and can transmit and receive signals to and from a user terminal within its cell coverage based on the CA method.
