Also, "a or an", "one", "the", and the like are used differently in the context of describing the present invention (particularly in the context of the following claims). Unless otherwise indicated or clearly contradicted by context, it may be used in the sense including both the singular and the plural.

Specific terms used in the embodiments of the present invention are provided to help the understanding of the present invention, and the use of the specific terms may be changed into other forms without departing from the technical spirit of the present invention.

The following techniques include code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and the like. It can be used in various radio access systems. CDMA may be implemented with a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA may be implemented with wireless technologies such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE). OFDMA may be implemented in a wireless technology such as IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, Evolved UTRA (E-UTRA). UTRA is part of the Universal Mobile Telecommunications System (UMTS). 3rd Generation Partnership Project (3GPP) long term evolution (LTE) is part of an Evolved UMTS (E-UMTS) using E-UTRA, and employs OFDMA in downlink and SC-FDMA in uplink. LTE-A (Advanced) is the evolution of 3GPP LTE.

For clarity, the following description focuses on 3GPP LTE / LTE-A, but the technical spirit of the present invention is not limited thereto.

1 is a diagram schematically showing an E-UMTS network structure as an example of a mobile communication system to which the present invention can be applied. The Evolved Universal Mobile Telecommunications System (E-UMTS) system is an evolution from the existing Universal Mobile Telecommunications System (UMTS), and is currently undergoing basic standardization in 3GPP. In general, the E-UMTS may be referred to as a Long Term Evolution (LTE) system.

Referring to FIG. 1, an E-UMTS includes a user equipment (UE), an evolved universal terrestrial radio access network (E-UTRAN), and an evolved packet core (epc).

E-UTRAN is an evolved network from the existing UTRAN. The E-UTRAN is composed of base stations (eNBs), and each base station is connected through an X2 interface. The base station is connected to the terminal through the air interface, and is connected to the Evolved Packet Core (EPC) through the S1 interface.

One or more cells exist in one base station. The cell is set to one of bandwidths such as 1.25, 2.5, 5, 10, 15, and 20Mhz to provide downlink or uplink transmission services to multiple terminals. Different cells may be configured to provide different bandwidths. The base station controls data transmission and reception for a plurality of terminals. For downlink (DL) data, the base station transmits downlink scheduling information, which is related to time / frequency domain, encoding, data size, and hybrid automatic repeat and reQuest (HARQ) request for data to be transmitted to the corresponding UE. Give information and more. In addition, the base station transmits uplink scheduling information to the terminal for uplink (UL) data and informs the user equipment of time / frequency domain, encoding, data size, and hybrid automatic retransmission request information. An interface for transmitting user traffic or control traffic may be used between base stations.

EPC is the core network (CN) of the E-UMTS, an evolution of the GPRS core network. EPC is an ALL-IP network divided into Control Plane and User Plane.

EPC includes Mobility Management Entity (MME), Serving-Gateway (S-GW), Packet Data Network-Gateway (PDN-GW), and Home Subscriber Server (HSS). The MME has information about the access information of the terminal or the capability of the terminal, and this information is mainly used for mobility management of the terminal. S-GW is a gateway having an E-UTRAN as an endpoint, and PDN-GW is a gateway having a PDN (Packet Data Network) as an endpoint. HSS is a central database (DB) with a user profile that provides the MME with user credentials and user profiles.

FIG. 2 is a diagram illustrating a control plane and a user plane structure of a radio interface protocol between a terminal and an E-UTRAN based on the 3GPP radio access network standard. The control plane refers to a path through which control messages used by a user equipment (UE) and a network to manage a call are transmitted. The user plane refers to a path through which data generated at an application layer, for example, voice data or Internet packet data, is transmitted.

The physical layer, which is the first layer, provides an information transfer service to an upper layer by using a physical channel. The physical layer is connected to the upper layer of the medium access control layer through a transport channel. Data moves between the medium access control layer and the physical layer through the transport channel. Data moves between the physical layer between the transmitting side and the receiving side through the physical channel. The physical channel utilizes time and frequency as radio resources. Specifically, the physical channel is modulated in the Orthogonal Frequency Division Multiple Access (OFDMA) scheme in the downlink, and modulated in the Single Carrier Frequency Division Multiple Access (SC-FDMA) scheme in the uplink.

The medium access control (MAC) layer of the second layer provides a service to a radio link control (RLC) layer, which is a higher layer, through a logical channel. The RLC layer of the second layer supports reliable data transmission. The function of the RLC layer may be implemented as a functional block inside the MAC. The PDCP (Packet Data Convergence Protocol) layer of the second layer performs a header compression function to reduce unnecessary control information for efficiently transmitting IP packets such as IPv4 or IPv6 in a narrow bandwidth wireless interface.

The Radio Resource Control (RRC) layer located at the bottom of the third layer is defined only in the control plane. The RRC layer is responsible for control of logical channels, transport channels, and physical channels in connection with configuration, reconfiguration, and release of radio bearers (RBs). The radio bearer refers to a service provided by the second layer for data transmission between the terminal and the network. To this end, the RRC layers of the UE and the network exchange RRC messages with each other. If there is an RRC connected (RRC Connected) between the UE and the RRC layer of the network, the UE is in an RRC connected mode, otherwise it is in an RRC idle mode. The non-access stratum (NAS) layer above the RRC layer performs functions such as session management and mobility management.

One cell constituting the base station (eNB) is set to one of the bandwidth, such as 1.25, 2.5, 5, 10, 15, 20Mhz to provide a downlink or uplink transmission service to multiple terminals. Different cells may be configured to provide different bandwidths.

The downlink transport channel for transmitting data from the network to the UE includes a broadcast channel (BCH) for transmitting system information, a paging channel (PCH) for transmitting a paging message, and a downlink shared channel (SCH) for transmitting user traffic or a control message. have. Traffic or control messages of a downlink multicast or broadcast service may be transmitted through a downlink SCH or may be transmitted through a separate downlink multicast channel (MCH). Meanwhile, the uplink transmission channel for transmitting data from the terminal to the network includes a random access channel (RAC) for transmitting an initial control message and an uplink shared channel (SCH) for transmitting user traffic or a control message. It is located above the transport channel, and the logical channel mapped to the transport channel is a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and an MTCH (multicast). Traffic Channel).

3 is a block diagram illustrating a wireless communication quality analysis system according to the present invention.

Referring to FIG. 3, the wireless communication analysis system of the present invention includes a terminal 310, a service device 330, and a base station 320. Also, a network management system 340 or a message transmission device 350 may be further included.

The wireless communication analysis system of the present invention refers to a system for analyzing and displaying the quality of wireless communication between the terminal 310 and the base station 320 for each region by using the location information and the quality information of the terminal 310.

The quality information is information for determining a quality of wireless communication between the terminal 310 and the base station 320. The quality information is a measure of a predetermined event occurring during wireless communication between the terminal 310 and the base station 320, and an event is generated. The number of times, the cause of occurrence, a history of occurrence of the log, and the like. Examples of events where quality information occurs include downlink and / or uplink throughput, service defects, handoff failures, random access, and wireless. A radio link fail, an attach fail, a channel quality indicator (CQI), or a call drop may be included.

Downlink and / or uplink Throughput

The downlink and / or uplink throughput information refers to the amount of data transmitted per unit time of uplink from the terminal 310 to the base station and / or downlink from the base station to the terminal 310. In this case, the amount of data transmitted per second may be expressed by the number of bytes or the number of bits.

Service defects

When the terminal 310 transmits / receives data between the base stations 320, an error occurs in the terminal 310 and / or the network, and thus the data transmission and reception fail.

Handover  failure

As the terminal 310 receives a handover command message from a source eNB, the terminal starts a handover start timer. If the terminal 310 fails to access the target eNB during the handover start timer period, that is, until the timer expires, the terminal 310 returns to the source base station. This handover failure may occur due to an MME rejection, random access failure, or the like.

Random access

The terminal 310 undergoes a random access procedure to access the base station 320. In this process, the terminal 310 transmits a random access preamble through a random access channel (RACH). At this time, when a plurality of terminals simultaneously transmit the same random access preamble to the same base station 320, collision occurs. In case of collision, the UE retransmits the random access preamble.

Wireless link failure

The terminal 310 and the base station 320 continuously monitor the occurrence of the radio link failure while the radio link is maintained. That is, the terminal 310 and the base station 320 signal the signals so that information is exchanged between the terminal and the base station when the reception of a physical channel connecting each other is equal to or less than the quality threshold value or when no reception is detected. If the transmitting physical channel fails), it can be recognized that the radio link has failed.

Connection failed

When the terminal 310 initially re-enters the service coverage after being powered on or out of the service coverage, the terminal 310 synchronizes with the base station 320 through a cell search process and then attaches to the network. Try. In this case, when the connection fails, the terminal may recognize this.

CQI  Information

The terminal 310 measures a radio channel state from a common RS and a CRS, and feeds back an indicator related to channel quality, such as a CQI, to the base station 320.

Disconnection ( Call drop )

This is when the call is disconnected due to a bad wireless section before the terminal 310 completes the call.

The above-described quality information is only an example and is not limited thereto. In addition, each quality information may be used independently of each other, and at least two or more quality information may be used together.

The terminal 310 refers to a device that measures quality information and transmits the measured quality information to the service device 330. In this case, the location information of the terminal 310 may also be transmitted. The terminal 310 may be any device as long as it is a communication device available to a user who can transmit and receive data through the base station 320. For example, the terminal 310 may include a personal computer (PC), a notebook computer, a mobile phone, a tablet PC, a smart phone, a personal digital assistant (PDA), and the like. Of course, this is only an example, and in addition to the above-described examples, it should be interpreted as a concept including all communication devices that are currently developed and commercialized or will be developed in the future.

The service device 330 is a device that collects quality information from the terminal 310 and analyzes the quality of wireless communication between the terminal 310 and the base station 320 for each region by using the collected quality information. In this case, when receiving location information from the terminal 310, the quality of wireless communication may be analyzed for each region using the received location information. On the other hand, when the location information is not received from the terminal 310, the location information of the terminal 310 may be determined from the mobile communication network.

The base station 320 performs a function of relaying data between the terminal 310 and the service device 330 and includes the original function of the base station of a general mobile communication network. In particular, in the present invention, the quality information of the terminal 310 is transmitted to the service device 330, and the control information of the service device 330 is transmitted to the terminal 310.

The network management system (NMS) 340 refers to a system that manages all components constituting the mobile communication network, that is, hardware and software. Includes features. In particular, in the present invention, the network management system may store a map including geographic information and provide a map upon request of the service device 330.

The message transmitting device 350 performs a function of transmitting information of the service device 330 to the terminal 310. The message transmission device 350 includes the original function of the existing short message service center (SMSC). The service device 330 may transmit and store control information to the terminal 310 through the message transmission device 350.

4 is a flowchart illustrating a wireless communication quality analysis method according to an embodiment of the present invention.

Referring to FIG. 4, the terminal 310 measures quality information (S401), and transmits the measured quality information and location information to the service device 330 through the base station 320 (S403).

In this case, for the convenience of description, the step of measuring the quality information by the terminal 310 is illustrated as S401 only, but the terminal 310 measures the quality information at each time point of an event related to the quality information.

The terminal 310 may accumulate and store the measured quality information. That is, the terminal 310 measures, accumulates and stores the quality information according to an event that has occurred for a preset time, and then transmits the accumulated quality information to the service device 330. In this case, the terminal 310 may delete the quality information accumulated for a predetermined period after transmitting the quality information to the service device 330. In addition, the terminal 310 may transmit the quality information generated every time an event occurs to the service device 330.

Meanwhile, since the terminal 310 is equipped with a global positioning system (GPS) module, the terminal 310 may receive a GPS signal and check the position of the terminal 310 using the received GPS signal. However, if the terminal 310 does not have a GPS module or if the GPS signal is weak and the location of the terminal 310 is not determined even when the GPS module is mounted, only the quality information except the location information is provided. Can also be sent. In addition, the terminal 310 transmits a basic factor of a cell such as a physical layer identity (PCI) as the location information, so that the service device 330 may roughly recognize the location of the terminal.

In addition, the terminal 310 may also transmit its identification information to the service device 330. In this case, as an example of identification information of the terminal 310, a mobile identification number (MIN), an international mobile subscriber identity (IMSI), a mobile subscriber number (MSN), an electronic serial number (ESN), and the like may be used.

The service device 330, which has received the quality information and the location information from the terminal 310, stores the quality information and the location information by matching each other therein (S405).

When the service device 330 receives the identification information of the terminal 310 together, the service device 330 may store quality information and location information corresponding to the identification information by dividing the identification information.

On the other hand, when the location information is not received from the terminal 310 in step S403, that is, when the GPS module is not mounted on the terminal 310, the service device 330 receives the location of the terminal 310 from the mobile communication network You can check it. In this case, the service device 330 preferably receives the identification information from the terminal 310 in order to confirm the location information of the terminal 310. As a method of determining the location of the terminal 310 using a mobile communication network, a Cell-ID technique, an Enhanced Cell-ID (ECID) technique, an Observed Time Difference Of Arrival (OTDOA) technique, or the like may be used.

Cell-ID is a technique for assigning a location-specific ID to each base station and, if the terminal is registered in the base station, matches the cell ID to obtain a location of the terminal through the location of the base station. The ECID technique is a method of improving accuracy by adding distance information between the base station and the terminal to the Cell ID technique. In this case, the distance information refers to a value excluding a response processing time in a terminal from a time when a base station requests a response to the terminal and a time when the base station receives a response from the terminal (Round Trip Time RTT). And,

The OTDOA technique is a technique in which a terminal measures a delay time of a signal received from each cell and reports it to a serving cell, and the serving cell measures a position of the corresponding terminal using the reported delay times.

The service device 330 storing the quality information and the location information requests the map information from the network management system 340 (S407), and receives the map information from the network management system 340 (S409).

In this case, the map information may be image data represented on the display device, or may be non-image data. In the case of non-image data, the service device 330 may convert the received non-image data into an image and display the data.

The service device 330 may receive the map information together with the geographic location information of the base station 320 and / or the cell radius information from the network management system 340. In addition, the service device 330 may receive only map information and map geographic location information and / or cell radius information of the base station 320 to map information. In addition, the service device 330 may store the map information therein, and in this case, the network management system 340 may not request the map information.

The service device 330 receiving the map information from the network management system 340 maps the quality information received from the terminal 310 onto the map (S411). As described above, when the map information is non-image data, data is converted into an image, that is, a map, and quality information is mapped onto the map. The service device 330 displays a map to which quality information is mapped through a display device connected to the service device 330. In this case, the display device may be mounted on the service device 330, and may be connected to the service device 330 by wire or wirelessly.

Hereinafter, the results of the embodiment according to FIG. 4 will be described with reference to the drawings.

5 illustrates an example of a map screen in which wireless communication quality is analyzed using handover failure information.

Referring to FIG. 5, the "dot" displayed on the map indicates that the terminal 310 has failed in handover. That is, when the handover fails, the terminal 310 transmits the location information of the terminal 310 together with the handover failure information to the service device 330. In addition, the service device 330 makes a specific indication indicating a handover failure on the map based on the received location information.

The display may be displayed on a map each time the quality information is received from the terminal 310, and may be displayed to correspond to the quality information received from the terminal 310 in a one-to-one correspondence. In addition, the quality information received from the terminal 310 may be statistically processed and displayed differently according to the shape, size, color, etc. of the display according to the statistical processing.

The service device 330 may analyze the quality state of the wireless communication for each specific region according to the density of the display displayed on the map.

The left side of FIG. 5A illustrates a screen in which map accumulation is relatively small, and the service device 330 may confirm the quality state of wireless communication in a wide area by reducing the accumulation of map. The right side of FIG. 5A illustrates a screen in which map accumulation is relatively large, and the service device 330 may check the quality state of wireless communication in a specific region in more detail by increasing the map accumulation. In addition, when the handover failure indications are concentrated in a specific region as shown in the left side of FIG. 5B, the outermost marks may be displayed in the shaded area following the dense marks (right side of FIG. 5B).

6 illustrates an example of a map screen in which wireless communication quality is analyzed using call disconnection information.

Referring to FIG. 6, the "dot" displayed on the map indicates that the call is disconnected while the terminal 310 does not complete the call. That is, when the call is disconnected, the terminal 310 transmits the location information of the terminal 310 together with the call disconnection information to the service device 330. In addition, the service device 330 may make a specific indication indicating disconnection on the map based on the received location information. The detailed description is the same as the map analyzing the wireless communication quality using the handover failure information in FIG. 5, and will not be described below.

As described above, the map analyzing the wireless communication quality according to FIGS. 5 and 6 may also be used to analyze other quality information.

7 illustrates an example of a map screen in which wireless communication quality is analyzed using uplink and / or downlink throughput information.

Referring to FIG. 7, the service device 330 may be classified into a specific binning area on a map to indicate wireless communication quality. In this case, the specific unit area may be set according to a user's designation, and may be set arbitrarily by the service device 330. When the service device 330 is set arbitrarily, the unit area may be set to be small in areas where the terminal 310 is densely packed or areas where statistics of quality information other than throughput are high. By setting the unit area small, it is possible to display in more detail than the other areas. That is, although all unit areas have the same size in FIG. 7, a specific area may be divided into more subdivided areas and displayed.

The terminal 310 measures uplink and / or downlink throughput and transmits the information to the service device 330 along with the location information. The service device 330 calculates an average value of throughputs of the terminals 310 belonging to the corresponding area on the map based on the received location information. In addition, a display corresponding to a throughput range divided by a predetermined unit for each unit area may be displayed. For example, the service device 330 displays a color corresponding to 3 Mbps to 5 Mbps when the average value of the throughputs of the terminals 310 belonging to the corresponding unit area is 4 Mbps. In this case, the service device 330 may change the display by using the maximum value or the minimum value of the throughput received from the terminal 310 belonging to the corresponding area.

On the other hand, if constant quality information is always collected from the terminal 310, battery consumption of the terminal 310 may occur, and a network overload problem may occur. Therefore, we propose a method to collect quality information step by step.

8 is a flowchart illustrating a wireless communication quality analysis method according to an embodiment of the present invention. Hereinafter, for the convenience of description, detailed description of the same steps as in FIG. 4 will be omitted.

Referring to FIG. 8, the service device 330 sets a base station list to which a collection class is assigned (S801). That is, the service device 330 differentially sets a grade regarding a degree of collecting quality information for each base station. For example, a class for collecting quality information of the base station A may be set to class 1, and a class for collecting quality information of the base station B may be set to class 2.

In this case, the degree of granularity of the grade or the difference in the information collected for each grade may be arbitrarily designated by the user or the service device 330. In addition, for convenience, the quality information collection class is classified for each base station, but a plurality of base stations may be bundled to designate the same class.

As an example of setting quality information collection level, level 1 is a level that collects only basic information of quality information, level 2 is a level that collects more detailed information than level 1, and level 3 is a level that collects all information. have.

In Level 1, the number of events such as radio link failure, connection failure, and service defect can be collected as quality information. In this case, details such as the reason for each event is not reflected in the quality information, and only the number of event occurrences may be designated as the quality information. The service device 330 may statistically analyze and analyze the number of event occurrences of each terminal 310 during a specific period in a coverage area serviced by each base station 320. In addition, each terminal 310 transmits a physical layer identity (PCI), which is a basic factor of a cell that is serviced to the service device 330 as location information, and the service device 330 approximates the location of each terminal 310. You can also figure out.

The second level may be designated when the statistical result of the statistical processing of the quality information collected by the service device 330 or the user exceeds a predetermined threshold. When the second level is designated, each terminal 310 may include the cause of occurrence of each event in the quality information in addition to the number of occurrences of each event and transmit the quality information to the service device 330. For example, in the case of handover failure information, the type of handover, whether the handover attempted by the terminal 310 is an X2 handover or an S1 handover, may be included in the quality information. In addition, the cause of the handover failure, such as random access failure (RACH failure), X2 setup failure, MME rejection, etc., may be included in the quality information. In addition, the information may be included as information on a defect state of each service, an application running when a defect occurs, and the like.

In the case of collecting the information of the second level, the collection time may be constantly limited in order to minimize battery consumption of the terminal 310. That is, after a specific time elapses from the time when the terminal 310 starts to transmit the second grade of quality information, the terminal 310 may be automatically changed to the first grade to transmit only the quality information corresponding to the first grade to the service device 330.

The third level may be designated when the service device 330 analyzes the cause of each quality information and the like and finds a specific cause. You can also specify commands from the user. When the third grade is designated, the terminal 310 may transmit all log information about the event to the service device 330 in the quality information.

The service device 330 transmits the base station list in which the collection class is designated to the terminal 310 (S803).

The service device 330 may periodically transmit a base station list to the terminal 310, and may transmit the updated base station list to the terminal 310 whenever the base station list is updated. In addition, the service device 330 may transmit base station information to the terminal 310 through the message transmission device 350.

In this case, the service device 330 may designate each class to each base station and transmit a base station list for all base stations to which the class is assigned to the terminal 310. That is, in the above-described example, the service device 330 may match each class 1, 2, or 3 class to all base stations, and may transmit a base station list for all base stations whose classes are matched to all terminals 310. . In addition, in the above-described example, only a base station list designated as a second or third class may be transmitted to all terminals.

The service device 330 may transmit the base station list only to the base station 320 designated as the second or third class, and may transmit the base station list only to the terminal 310 serviced by the base station 320 designated as the second or third class. In this case, the service device 330 may transmit a base station list in a broadcast format through the base station 320.

Upon receiving the base station list from the service device 330, the terminal 310 checks whether a serving eNB that is being serviced is included in the base station list (S805). The terminal 310 may check whether the base station list is included in the base station list through the identifier of the serving base station, and may check the quality information collection class of the serving base station in the base station list.

After checking the base station list, the terminal 310 measures the quality information (S807) and transmits the quality information according to the quality information collection class of the cell to which it belongs together with the location information to the service device 330 (S809). In this case, as described above, the terminal 310 may transmit only the quality information except the location information to the service device 330.

The service device 330 that has received the quality information and the location information stores the quality information by matching the location information with the location information (S811). As described above, when the location information is not received from the terminal 310, the service device 330 may grasp the location information of the terminal 310 from the mobile communication network.

The service device 330 storing the quality information and the location information requests the map information from the network management system 340 (S813), and receives the map information from the network management system 340 (S815).

The service device 330 receiving the map information from the network management system 340 maps the quality information received from the terminal 310 onto the map (S817).

Meanwhile, the terminal 310 may delete the stored base station list at a point in time after receiving and storing the base station list. In addition, the terminal 310 may delete the stored base station list when the area where it is located is not included in the base station list, that is, when only the first grade quality information is transmitted to the service device 330.

8, the service apparatus 330 transmits a list of base stations to which a quality information collection class is assigned to the terminal 310 to differentially collect quality information from the terminal 310. Hereinafter, the embodiment according to FIG. 9 proposes a method of confirming the position of the terminal 310 and transmitting a base station list according to the position of the terminal 310.

9 is a flowchart illustrating a wireless communication quality analysis method according to an embodiment of the present invention. Hereinafter, for the convenience of description, detailed descriptions of the same steps as FIGS. 4 to 8 will be omitted.

Referring to FIG. 9, the service device 330 sets a base station list to which a collection class is assigned (S901).

The terminal 310 measures the quality information (S903), and transmits the measured quality information and the location information to the service device 330 through the base station 320 (S905). In this case, as described above, the terminal 310 may transmit only the quality information except the location information to the service device 330.

The service device 330 receiving the quality information and the location information checks the location of the terminal 310 using the received location information (S907). As described above, when the location information is not received from the terminal 310, the service device 330 may determine the location of the terminal 310 from the mobile communication network.

After checking the location of the terminal 310, the service device 330 transmits a base station list to the corresponding terminal 310 when the location of the terminal 310 belongs to a specific area (S909).

As described with reference to FIG. 8, the service device 330 may transmit the base station list only to the terminal 310 belonging to the base station 320 designated as the second or third class. That is, the service device 330 may transmit the base station list only to the corresponding terminal 310 when the terminal 310 confirms to the terminal 310 located in the base station 320 designated as the second or third class. In this case, the service device 330 may transmit the base station list only to the corresponding terminal 310 in a multicast format through the base station 320.

In addition, when the terminal 310 is located in a cell adjacent to the area of the base station 320 designated as the second or third class, the base station list may also be transmitted to the corresponding terminal 310. This is because the terminal 310 is likely to move to the region of the base station 320 designated as the second or third class. In this case, the terminal 310 may store the received base station list and may refer to the stored base station list when the cell is moved later.

Upon receiving the base station list, the terminal 310 checks the quality information collection class of the base station 320 to which it belongs, and transmits the quality information according to the changed level to the service device 330 through the base station 320 together with the location information. (S911).

In this case, the quality information measurement is shown to be performed only in step S903 for convenience of description, but the quality information measurement of the terminal 310 is repeatedly performed when a corresponding event occurs. In addition, as described above, the terminal 310 may transmit only the quality information except the location information to the service device 330.

In addition, when the base station list is transmitted to the terminal 310 located in the cell adjacent to the area of the base station 320 designated as the second or third class in step S909, the corresponding terminal 310 is assigned to the second or third class. 320, when moving to the area, the quality information according to the corresponding class may be transmitted with reference to the base station list.

The service device 330 that has received the quality information and the location information stores the quality information by matching the location information with the location information (S913). As described above, when the location information is not received from the terminal 310, the service device 330 may grasp the location information of the terminal 310 from the mobile communication network.

The service device 330 storing the quality information and the location information requests the map information from the network management system 340 (S915), and receives the map information from the network management system 340 (S917).

The service device 330 receiving the map information from the network management system 340 maps the quality information received from the terminal 310 onto the map (S919).

Hereinafter, an example in which the service apparatus 330 according to FIGS. 8 and 9 applies a method of transmitting a base station list having a matching quality information collection grade to the terminal 310 will be described.

10 is a diagram illustrating a scenario according to a wireless communication quality analysis method according to an embodiment of the present invention.

As described above, when transmitting the base station list matching the quality information collection level to all the terminal 310, all the terminal 310 may know the quality information collection level regardless of the movement of the terminal 310. . Hereinafter, it is assumed that the base station list is transmitted only to the terminal 310 belonging to a specific region. In addition, description will be made according to the above-described quality information collection class.

Referring to FIG. 10, each area shown by a hexagon represents a service coverage of each base station, that is, an area of a cell. Since the hexagon is only one example for explaining the present embodiment, the area of the cell may be in any form. Each cell is a cell area (not spot area) designated as a collection class of quality information in a normal state and a cell area (hereinafter, referred to as NSA area) that requires more detailed quality information collection. SA area).

When the terminal 310 is in the NSA area, the terminal 310 does not receive the base station list and does not know the base station list, and thus the terminal 310 transmits only the quality information corresponding to the first grade to the service device 330. do.

Subsequently, as shown in FIG. 10A, when the terminal 310 moves from the NSA region ① to the NSA region ②, the terminal 310 continuously maintains only the quality information corresponding to the first grade. 330).

On the other hand, as shown in FIG. 10B, when the terminal 310 moves from the NSA region ① to the SA region ③, the terminal 310 is a base station to which a quality information collection class is assigned from the service apparatus 330. Receive the list. The terminal 310 confirms that a serving cell registered with the terminal 310 is included in the base station list. The terminal 310 transmits the quality information to the service device 330 by referring to the corresponding grade of the serving cell. At this time, the quality information collection grade of the serving cell may be a second or third grade.

However, when the terminal 310 receives the base station list of which the quality information collection grade is updated from the service device 330, the terminal 310 transmits the quality information to the service device 330 with reference to the updated base station list. For example, when the serving cell has a grade 2 when the terminal 310 enters the serving cell, the terminal 310 transmits quality information corresponding to the grade 2 to the service device 330. Subsequently, when the serving cell receives a list of base stations designated as a third grade from the service apparatus 330, the terminal 310 transmits quality information corresponding to the third grade to the service apparatus 330.

Subsequently, as shown in (c) of FIG. 10, when the terminal 310 moves from the SA area ③ to the SA area ④, the terminal 310 refers to the stored base station list, and the serving is registered. Confirm that the cell is included in the base station list. The terminal 310 transmits the quality information to the service device 330 by referring to the corresponding grade of the serving cell. For example, if the cell before the movement is designated as the second grade and the cell after the movement is designated as the third grade, the terminal 310 moves the cell and simultaneously transmits quality information corresponding to the third grade to the service device 330. . However, when the terminal 310 receives the base station list of which the quality information collection grade is updated from the service device 330, the terminal 310 transmits the quality information to the service device 330 with reference to the updated base station list.

As shown in (d) of FIG. 10, when the UE 310 moves from the SA area ④ to the NSA area ⑤, the UE 310 refers to the stored base station list, and the serving cell to which the UE 310 is registered. It can be confirmed that it is not included in the base station list. The terminal 310 transmits only the quality information corresponding to the first grade to the service device 330. In addition, as described above, the terminal 310 may delete the received stored base station list.

On the other hand, if the base station list is also transmitted to the terminal 310 located in the cell adjacent to the SA area, even if the terminal 310 is located in the NSA area (①, ②), the service device 330 sends the base station list to the terminal 310. Can transmit Further, even when the terminal 310 moves from the SA area ④ to the NSA area ⑤, the terminal 310 may not delete the base station list since it is still located in a cell adjacent to the SA area.

Hereinafter, when the service device 330 transmits a base station list to the terminal 310, the range of the base station list to be transmitted will be described.

11 is a diagram illustrating a range of a base station list transmitted to a terminal by a service apparatus according to an embodiment of the present invention.

Referring to FIG. 11, it is assumed that the terminal 310 is located in the SA region ④. The service device 330 transmits a list of base stations to which the quality information collection class is assigned to the terminal 310. The service device 330 sets a range up to an adjacent area together with a cell where the terminal 310 is located, to the terminal 310. ) Can be sent. That is, the base station list indicating that the cells ③, ④, ⑥, and ⑦ areas are SA areas may be transmitted.

On the other hand, the service device 330 may set up to the SA area connected to the cell where the terminal 310 is located as a range and transmit it to the terminal 310. That is, the base station list indicating that the cells ③, ④, ⑥, ⑦, ⑧ areas are SA areas can be transmitted.

Meanwhile, the above-described method may also be applied to the case where the base station list is also transmitted to the terminal 310 located in the cell adjacent to the SA region. That is, when the terminal 310 is located in the NSA area ①, the service device 330 is connected to the cell ③, ④, ⑥, ⑦ area or the cell ③, ④, ⑥, ⑦, ⑧ area of the terminal 310. The base station list may be transmitted.
