Description

[0001] The present invention relates to a method of diagnosing a wireless AP in a bus,

The present invention relates to a method of diagnosing a wireless AP failure in a bus.

Wireless Internet services include WiFi, Wibro, EVDO, LTE (Long Term Evolution), and others.

Among them, a wireless LAN (WiFi) is called a wireless fidelity or a WLAN (Wired LAN) and conforms to the IEEE 802.11-1999 standard, and connects an access point (AP) to a wired LAN network A wireless terminal, a notebook computer, etc. are wirelessly connected to the Internet to connect to the Internet. [0003] The Institute of Electrical and Electronic Engineers (IEEE) 802 standard is a series of LANs developed by the IEEE 802 committee Connection methods and protocol standards.

The reference model of the IEEE 802 standard protocol is based on the concept of layering of the OSI reference model, and it standardizes mainly the lower two layers out of the seven layers of the OSI model.

The wireless LAN service uses the ISM band (unlicensed band) of 2,400 to 2,483 GHz which complies with the IEEE 802.11b / g international standard and has narrow coverage due to frequency interference with other communication services and low power. Therefore, the 2.4 GHz band wireless LAN service is used locally for indoor and narrow coverage hotspots.

Since the wireless LAN system can be easily interworked with the Internet network and is produced and supplied according to the system specification according to the international standard, the use of the wireless LAN system is spreading due to advantages such as an inexpensive device price and high speed data transmission.

Meanwhile, as smartphones become more popular, demand for and interest in wireless Internet has increased. However, infrastructure and infrastructure are still lacking. Even if the WiFi zone, which is a wireless LAN area, is well-equipped, there is a problem that the use of the wireless LAN is limited due to the policy of each communication company, or a confusion occurs due to redundant installation.

Therefore, as the use of portable IT devices increases and the speed of development rapidly changes, it is necessary to install a wireless Internet infrastructure according to the environment and applications and to establish a professional design. In particular, wireless APs are being used to continuously use wireless LANs in transportation such as buses.

On the other hand, when the wireless AP mounted on such a bus fails to properly supply the wireless communication service to the passenger terminal of the passenger who has boarded the bus, the manager has to go to the bus and go to check whether the wireless AP has actually failed. However, the wireless AP mounted on the bus is not a malfunction. Instead, the bus is intentionally turned off by the bus driver because the bus is stationary in the garage, and the power is not supplied to the wireless AP, There is a case. In some cases, the bus temporarily does not communicate with the control server side through a shadow area such as a tunnel, an underground driveway, or a high-rise building forest. The failure of the wireless AP between the wireless APs of the temporary control server rather than the failure of the wireless AP may occur on the bus in order to determine whether the wireless AP is not faulty. However, the wireless AP is not a real failure, and a management worker leaks. The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2014-0147202 (December 30, 2014).

1 is a flowchart of a wireless AP failure determination according to an exemplary embodiment of the present invention. Referring to FIG. 1, the control server transmits a first signal to a wireless AP (Access Point) installed in a bus (S 110); (S120) the control server waits for a first time to transmit a second signal to be transmitted in response to the first signal from the wireless AP; (S170) when the control server requests the location information of the bus to the traffic management server that controls the bus when the first time passes while the control server fails to receive the second signal; When the control server receives the location information from the traffic management server, determining whether the location of the bus is within a predetermined zone based on the location information (S180); When the control server determines that the location of the bus exists outside the predetermined area, the control server determines that the wireless AP is out of order (S190).

When each step is examined in detail, a control server managed by a wireless LAN AP (hereinafter referred to as a wireless AP) mounted on a plurality of buses transmits a signal to a wireless AP installed in the bus. The signal may be a control request signal. The control request signal may include an IP address of the control server, a period during which the wireless AP reports to the control server, a wireless AP reboot request signal, a firmware upgrade request signal of the wireless AP, Set Identifier) setting signal, Wi-Fi channel, and the like. In the meantime, in the present invention, the control server confirms whether or not the wireless AP mounted on the bus is faulty. The control server identifies the wireless AP to be managed, information about the bus equipped with the wireless AP Number, bus dispatch interval, bus route map information, average moving speed according to each bus route section, bus driver information, bus driver accident history, etc.).

The wireless AP that receives this signal sends a response signal to the control server. The control server waits until the response signal is received. That is, the control server waits for a preset time.

If the control server sends a control signal to the wireless AP, the control server requests the location information of the bus to the traffic management server. The traffic management server can be physically separated from the control server and can be configured separately from the control server by using the route number of the bus to be managed, the bus identification number, the bus dispatch interval, the bus route map information, the wireless AP identification information mounted on the bus, The average speed for all, the average speed for each route section, etc.), bus driver information, and the like. The location information of the bus can be obtained by combining the information such as the bus route map stored in the traffic management server, the departure time from the starting point based on the route map, and the average speed of the bus, . For example, in the case of a wide area bus, it is possible to estimate whether the current estimated position is a highway specific point by substituting the average travel speed information according to the time and the section starting from the starting point on the route map information operated through the highway. This makes it possible to estimate the position of a bus on a highway with many tunnel sections where the GPS sensor may not operate.

Thereafter, the control server receives the location information of the bus from the traffic control server, and determines whether or not the bus is in the predetermined zone. The predefined zone may be a garage, a shaded area where radio communication is interrupted (eg, a tunnel, an overpass, an underpass, near a high-voltage line, a high-rise building), or a place where an administrator has disabled the wireless AP. For example, in a garage where a bus is parked, the main battery is normally shut down because the bus driver is off, so the wireless AP does not work. Also, in places such as tunnels, the strength of the radio signal is weak, and communication between the control server and the wireless AP may not be smooth. In this way, the wireless AP is not actually physically broken down but uses a preset location or area that is estimated to be unsuccessful in communication between the wireless AP and the control server due to external environmental factors.

If the control server determines that the bus is in a predetermined zone and the bus is outside the predetermined zone (i.e., the zone where the wireless communication is smooth), the control server transmits the bus to an area where radio communication is sufficiently feasible .

Thereafter, if it is judged that the area is out of the predetermined area, it finally judges that the wireless AP mounted in the bus is faulty.

If the bus is located in a garage or the like, the wireless AP is not judged as a failure, and the dispatch due to a faulty fault can be drastically reduced.

Meanwhile, when the first time passes while the control server fails to receive the second signal, the control server requests the location information of the bus to the traffic management server controlling the bus (S170) (S110) of sending a first signal to a wireless AP (Access Point) installed in the bus in the control server, and the control server sends a second signal to be transmitted in response to the first signal from the wireless AP to the wireless AP (S120) may be repeated several times, and finally the location of the bus may be requested. For example, when the control server requests the first signal to the wireless AP and then waits for a response three times, and if the wireless AP does not respond for three times, the location information of the bus may be finally requested to the traffic management server.

2 is a flowchart of a wireless AP failure determination according to another embodiment of the present invention. 2, in step S101, the control server prepares to transmit a first signal to a wireless AP installed in the bus at a first time; (S103) if the control server determines that the first time is included in the predetermined wireless AP utilization time information; If the first time is included in the wireless AP availability time information, transmitting the first signal to the wireless AP installed in the bus (S110); (S120) the control server waits for a first time to transmit a second signal to be transmitted in response to the first signal from the wireless AP; (S170) when the control server requests the location information of the bus to the traffic control server controlling the bus when the first time passes while the control server fails to receive the second signal; (S180), when the control server receives the location information from the traffic control server, determining whether the location of the bus is within a predetermined zone based on the location information; When the control server determines that the location of the bus exists outside the predetermined area, the control server determines that the wireless AP is out of order (S190).

Except for the overlapping description with other embodiments, this embodiment includes a step in which the control server determines whether the time at which the wireless AP transmits a signal is within the available time of the wireless AP. More specifically, the wireless AP availability time information is information on a predetermined time when the wireless AP installed in the bus should normally operate. For example, it is desirable that the wireless AP should be in operation during the bus operation, and the wireless AP may not operate during the time the bus is parked in the garage. That is, for example, it is a time for the wireless AP to operate normally from 6:00 am to midnight, and it is not necessary for the wireless AP to operate from midnight to 6:00 am. Because there are no passengers. In this way, the time information that the wireless AP should operate, that is, the time information to be utilized, is summarized, and the wireless AP utilization time information is defined as data. The wireless AP availability time information is not limited to the above-described example, but may be further specified by time period according to the route information. For example, in the case of a bus that operates only in the middle of the night, the wireless AP utilization time information may be set to the night time zone, and in the case of the school or institute bus, .

Thereafter, the control server checks in advance whether the time of transmitting the signal to the wireless AP is included in the wireless AP utilization time, and transmits the signal only when the wireless AP is within the available time. Thus, it is possible to prevent signal transmission if it is not possible to utilize the wireless AP utilization time, thereby preventing resources that are unnecessarily consumed. In addition, it is possible to reduce unnecessary checking of the failure of the wireless AP when the wireless AP is not available. The following procedure is omitted because it is redundant with the previous description.

3 is a flowchart illustrating a wireless AP failure determination according to another embodiment of the present invention. Referring to FIG. 3, the control server transmits a first signal to a wireless AP installed in a bus (S10). The control server receiving (S20) a second signal to be transmitted in response to the first signal from the wireless AP; Storing the identification information of the wireless AP, the transmission time of the first signal, the reception time information of the second signal, and the transmission / reception success according to each time in the database (S31); The control server repeats the previous three steps to store a plurality of transmission time, reception time information, and transmission / reception success according to each time (S40); (S51) of generating the wireless AP utilization time information based on the plurality of transmission times, the reception time information, and the success or failure of transmission / reception according to each time stored in the database by the control server; (S101) of preparing the control server to transmit the first signal to the wireless AP installed in the bus at the first time; (S103) if the control server determines that the first time is included in the wireless AP availability time information; If the first time is included in the wireless AP availability time information, transmitting the first signal to the wireless AP installed in the bus (S110); (S120) the control server waits for a first time to transmit a second signal to be transmitted in response to the first signal from the wireless AP; (S170) when the control server requests the location information of the bus to the traffic management server that controls the bus when the first time passes while the control server fails to receive the second signal; When the control server receives the location information from the traffic management server, determining whether the location of the bus is within a predetermined zone based on the location information (S180); When the control server determines that the location of the bus exists outside the predetermined area, the control server determines that the wireless AP is out of order (S190).

In the present embodiment, the control server transmits a first signal to a wireless AP installed in the bus (S10); The control server receiving (S20) a second signal to be transmitted in response to the first signal from the wireless AP; Storing the identification information of the wireless AP, the transmission time of the first signal, the reception time information of the second signal, and the transmission / reception success according to each time in the database (S31); The control server repeats the previous three steps to store a plurality of transmission time, reception time information, and transmission / reception success according to each time (S40); The control server further includes a step (S51) of generating the wireless AP availability time information based on the plurality of transmission times, the reception time information, and the success / failure of transmission / reception according to each time stored in the database .

More specifically, the control server sends and receives signals to and from the wireless AP. In this process, the control server generates identification information of the wireless AP to be transmitted, the time at which the signal was transmitted, the time at which it was received in response to the transmitted signal, and a value indicating whether the transmission and reception were completed and succeeded. This information is stored in the database. The control server repeats this process with the wireless AP several times and generates a plurality of data on the transmission time, reception time information, and success / failure of transmission / reception according to each time, finally generates wireless AP utilization time information and stores it in the database do. For example, in the case of a school bus, when the control server transmits a signal to a wireless AP installed on a school bus, transmission and reception with the wireless AP may succeed normally in the school time zone. That is, the control server repeatedly transmits and receives signals to and from the wireless AP installed on the school bus, so that the wireless AP of the school bus can be operated at any time of the day. The same operation as in the previous embodiment can be performed through the wireless AP availability time information obtained through this process. Thus, even if the administrator of the control server does not set the wireless AP utilization time information on the bus, it can acquire the wireless AP utilization time information and can utilize the most optimized wireless AP according to characteristics such as route and position of the bus Time information can be generated.

4 is a flowchart of a wireless AP failure determination according to another embodiment of the present invention. Referring to FIG. 4, the control server transmits a first signal to a wireless AP installed in a bus (S10). The control server receiving (S20) a second signal to be transmitted in response to the first signal from the wireless AP; Storing the identification information of the wireless AP, location information of the bus at the reception time of the second signal, and transmission / reception success according to each time in the database by the control server (S35); The control server repeats the above three steps to store location information of a plurality of buses and transmission / reception success or failure information according to each location (S40); (S55) of generating and storing in the database the wireless AP useable location information based on the location information of the plurality of buses stored in the database and the success / failure of transmission / reception according to each time; (S110) the control server transmits a first signal to a wireless AP installed in the bus; (S120) the control server waits for a first time period for a second signal to be transmitted in response to the first signal from the wireless AP; (S170) when the control server requests the location information of the bus to the traffic management server that controls the bus when the first time passes while the control server fails to receive the second signal; (S180) when the control server receives the location information from the traffic management server, based on the location information, determining whether the location of the bus is within a predetermined area of the wireless AP utilization available location information; When the control server determines that the location of the bus exists outside the predetermined area in the wireless AP availability location information, the control server determines that the wireless AP is out of order (S190).

The control server stores in the database the identification information of the wireless AP, the position information of the bus at the reception time of the second signal, and the success or failure of transmission / reception according to each time step; The control server repeating the above three steps to store location information of a plurality of buses and success / failure of transmission / reception according to each location; And generating the wireless AP utilization availability information based on the location information of the plurality of buses stored in the database and the success / failure of transmission / reception according to each time, and storing the wireless AP utilization availability information in a database.

More specifically, the control server acquires the real-time bus position when receiving and sending signals to the wireless AP, and stores it in the database. Of course, the success or failure of transmission is stored in the database. Whether or not to receive the data in response to the transmission and the bus position at that time are stored in the database. This process is repeated. Through this, it is possible to generate information such as which position the wireless AP installed in the bus and the control server normally communicate and communicate with. For example, if the bus is located in the straight line at latitude 37.477242,127.012682, longitude 37.4773797,127.0126358, latitude 37.4630204, latitude 127.01827409999999, and the wireless AP does not repeatedly respond to the signal from the control server, this straight- It can be assumed that the transmission / reception does not occur due to the external environment depending on the bus position regardless of the failure of the AP, and it can be set as the wireless AP utilization availability information. From the actual latitudes 37.477242, 127.012682, the longitude 37.4773797, 127.0126358 to the latitude 37.4630204 and the latitude 127.01827409999999, the signal can be shaded to the location where the right side tunnel exists.

As described above, even if the wireless AP does not respond to the wireless AP, it is not determined that the wireless AP does not respond, thereby preventing unnecessary trouble transmission. In addition, the administrator of the control server does not need to individually set the location information of the wireless AP through the learning.

5 is a flowchart illustrating a wireless AP failure determination according to another embodiment of the present invention. Referring to FIG. 5, the control server transmits a first signal to a wireless AP installed in a bus (S10). The control server receiving (S20) a second signal to be transmitted in response to the first signal from the wireless AP; The control server transmits the identification information of the wireless AP, the transmission time of the first signal, the reception time information of the second signal, the position information of the bus at the reception time of the second signal, Storing in a database (S37); The control server repeats the above three steps to store a plurality of transmission time, reception time information, position information of the plurality of buses, and transmission / reception success or failure according to each time and position (S40); The control server generates wireless AP utilization information based on the plurality of transmission times, the reception time information, the plurality of bus locations, and the success or failure of transmission and reception according to each time and location stored in the database, (S57); (S101) of preparing the control server to transmit a first signal to a wireless AP installed in the bus at a first time; (S103) if the control server determines that the first time is included in the wireless AP availability information; If the first time is included in the wireless AP utilization information, the control server transmits a first signal to a wireless AP installed in the bus (S110); (S120) the control server waits for a first time to transmit a second signal to be transmitted in response to the first signal from the wireless AP; (S170) when the control server requests the location information of the bus to the traffic management server that controls the bus when the first time passes while the control server fails to receive the second signal; (S180), when the control server receives the location information from the traffic management server, determining whether the position of the bus is included within the wireless AP utilization information based on the location information; When the control server determines that the location of the bus is outside the wireless AP available information area, the control server determines that the wireless AP is out of order (S190).

In the present embodiment, the position and time information of the bus that is successfully communicated between the control server and the wireless AP are generated and stored as wireless AP utilization information and stored. Accordingly, it is possible to more precisely determine whether or not the wireless AP is actually broken down by determining the time and space information to be successfully communicated between the control server and the wireless AP over time and space. That is, when the wireless AP is in a time and space in which the success of the communication success is low, it is possible to test whether the wireless AP fails again without judging it as a failure immediately, and as a result, unnecessary failure dispatch can be reduced.

FIG. 6 is a flowchart of a wireless AP failure determination according to another embodiment of the present invention. Referring to FIG. 6, the control server transmits a first signal to a wireless AP installed in a bus (S10). (S120) the control server waits for a first time to transmit a second signal to be transmitted in response to the first signal from the wireless AP; If the first time passes while the control server fails to receive the second signal, the control server requests real-time location information of the bus to the traffic management server controlling the bus at the tenth time S175); When the control server fails to receive the real-time location information from the traffic management server, the control server transmits the final position information of the bus stored in the traffic management server to the traffic management server and the generation time Requesting information (S177); Determining whether the location of the bus is within a predetermined zone based on the final location information and the generation time information; When the control server determines that the location of the bus exists outside the predetermined area, the control server determines that the wireless AP is out of order (S190).

In the case where the first time elapses without the control server receiving the second signal, the control server transmits a control signal to the traffic management server, which controls the bus, At the 10 < th >time; When the control server fails to receive the real-time location information from the traffic management server, the control server transmits the final position information of the bus stored in the traffic management server to the traffic management server and the generation time Requesting information; And the control server judges whether the position of the bus is included within a predetermined zone based on the final position information and the generation time information.

More specifically, when the control server does not receive a signal from the wireless AP installed in the bus, the control server requests the location of the bus to the traffic management server at a specific time. If the control server does not receive the real time location of the bus from the traffic management server, the control server once again requests the last location information of the bus stored by the traffic management server and the time information of the last location information. Accordingly, it is possible to determine the position of the bus in consideration of the final position and the time at which the position information is generated, and to determine whether the bus is within the set zone based on the position.

For example, the control server requests the 13:00 bus location to the traffic management server. However, the traffic management server does not respond to the location of the real-time bus in response to such a request. The control server again requests the traffic management server to determine when the final position and final position information of the bus stored in the traffic management server is generated. The control station receives information that the final position of the bus is 37.477242, 127.012682, 37.4773797, 127.0126358, and the final position is 12:55. Based on the information received, the location of the bus is estimated based on the information stored on the bus, such as the average speed of the routes and the entire route of the bus, the average speed of the route stop intervals, the average speed according to the time, can do. Based on the estimated bus position, it is determined whether or not the zone is the predetermined zone.

Of course, the final position is estimated by mixing the generated time information and existing stored information, utilizing critical information. More specifically, the step of determining, by the control server, based on the final position information and the generation time information that the position of the bus is included within a predetermined zone, The control server can determine whether the position of the bus is included within a predetermined zone based on the final position information and the generation time information. The present invention is not limited to this, but it is also possible to provide a method of generating the position information of the final bus, the route information of the bus, the average speed of the entire route, the average speed of the route, And so on.

In the present invention, the location of the bus is determined by requesting the location information of the bus to the traffic management server, but the present invention is not limited thereto. When there is no GPS reception information of the bus, the route information of the bus, the operating time information, the average traveling speed per route, the average traveling speed per route section (for example, And the real time traffic information, etc., and can use the bus position information instead of the real time bus position information. Of course, as mentioned above, it is also possible to estimate the position of the bus by combining various information before the last position information of the bus and the last position information generation information such as the traffic control server.

FIG. 7 is a flowchart according to another embodiment of the present invention, and FIG. 8 is a flowchart according to another embodiment of the present invention.

7 and 8, the present invention includes a step S210 of the control server receiving identification information of the first terminal and identification information of one or more other terminals from the first terminal. Storing the identification information of the first terminal and the identification information of the other terminal in the first database (S220); (S230) of the identification information of the other terminal among the identification information previously stored in the first database by the control server; If the identification information of the other terminal is found, the control server determines whether the identification information associated with the other terminal in the first database is identification information of the first terminal (S240). And transmitting a matching success message to at least one of the first terminal and the second terminal if the identification information of the first terminal is determined.

Specifically, the first terminal may be a terminal of a first user, and the other terminal may be a terminal of a third person aboard a bus on which a first user may feel a crush or may share a mobile line such as a carpool. The terminal may be a mobile phone such as a general smart phone, and the identification information may be a telephone number. In general, most people have cell phones and can identify people by phone number. However, the identification information is not limited to a telephone number, and may be information that can identify a user such as a smartphone application user ID, a computer software user ID, a messenger ID, a social network service ID, and an e-mail address.

When the control server receives the identification information of the first terminal and the other terminal, the control server temporarily stores the identification information in the database. The control server then searches the database to see if the identification number of the other terminal is included in a plurality of identification numbers stored in advance. If the control server determines that the identification number of another terminal is present, the control server determines again whether the identification information associated with the other terminal in the database is identification information of the first terminal, If the identification information of the first terminal is the identification information of the first terminal, the control server transmits a message indicating that the matching between the first terminal and the other terminal is successful. The meaning of the separate identification information associated with the other terminal is input to the control server by inputting the identification information of another user who is liked by the user of the other terminal or who can move to the same copper line. And the like. Of course, the separate identification information associated with the other terminal may also be stored in the database.

On the other hand, if the different identification information associated with the other terminal is not the identification information of the first terminal, the control server transmits a message indicating that the matching has failed only to the first terminal. If it is determined that the identification number of the other terminal does not exist in the database, that is, if the identification number of the other terminal does not exist in the database, the control server determines that matching has failed And transmits a message of contents. Accordingly, the user of the first terminal can determine whether the other person feels favorable to him or not and can use carpools or the like at a later time.

Meanwhile, the message indicating the success and failure of the matching used in the present invention can be used not only for a text message used in a smart phone, but also for a message such as an ARS automatic wire telephone notification, a messenger notification message, an application push message, It is a concept to include.

9 is a flowchart according to another embodiment of the present invention.

The control server searches whether the identification number of the other terminal is included in the plurality of identification numbers stored in advance and if the identification number of the other terminal exists and the identification number of the other terminal If it is determined that the identification information is the identification information of the first terminal, a message indicating that the first terminal and the other terminal have succeeded in matching is transmitted (S245, S250). Also, if it is determined that the identification information of the other terminal does not exist or that the different identification information associated with the other terminal is not the identification information of the first terminal, the control server waits for a predetermined time, (S247, S250). By sending the matching success or the matching failure message at the preset time, the user can increase the tension on the matching with the time margin. In addition, since a matching success or matching failure message can be sent to a plurality of terminals accumulated at the same time, it is possible to enjoy a festival effect such as a matching day in which a plurality of dates are concurrently achieved.

10 is a flowchart according to another embodiment of the present invention.

In other words, if the control server receives the identification number of the other terminal from the first terminal, the control server can transmit charging information to the first terminal again (S215). For example, when the first terminal transmits a smartphone number of one other, the control server can transmit to the first terminal billing information related to one identification number confirmation to the first terminal. On the other hand, when the first terminal transmits the smartphone numbers of a plurality of others, the control server can transmit to the first terminal billing information corresponding to a plurality of identification number confirmation to the first terminal. In addition, when the first terminal transmits an option parameter capable of immediately receiving the matching result from the control server together, the control server can immediately transmit to the first terminal billing information for the price indicating the matching result. On the other hand, as described above, when the first terminal transmits to the control server an option parameter that receives the matching result after the lapse of time, the control server can transmit the billing information to the first terminal. In this manner, the control server can transmit the billing information to the first terminal according to the requirements of the first terminal.

11 is a flowchart according to another embodiment of the present invention.

The redundant explanation may be omitted, and the identification information of the first terminal and the other terminal may be deleted from the database after a predetermined time has elapsed from the time when the control server transmits the matching failure message to the first terminal (S260 ). For example, if the identification number of the other terminal is not matched because it does not exist in the database, the terminal may send a matching failure message to the first terminal and continue to store the identification number of the first terminal in the database for one month thereafter. If different identification information associated with the other terminal is transmitted from the other terminal to the first terminal within one month, the matching between the first terminal and the other terminal is finally performed, and a matching success message is transmitted to each terminal Lt; / RTI > However, if another identification information related to another terminal is transmitted from another terminal as identification information of the first terminal after one month, the identification number of the first terminal and the identification number of the other terminal have already been deleted from the database It may not be retrieved, and as a result, no matching occurs. Through such a deletion step, it is possible to avoid the matching party of the dating who has lost their timeliness. Also, in order to be matched, the identification number of another terminal must be provided again from the first terminal, so that the operator of the control server obtains an opportunity to charge the terminal once again. On the other hand, the deletion of the identification number in the database does not need to be an actual physical deletion, and it is sufficient to process it so that it can not be retrieved.

12 is a flowchart according to another embodiment of the present invention.

In the case where the search or matching fails, the control server may transmit a message to the first terminal continuously asking whether to store the identification number of the first terminal and the other terminal after a lapse of time S270). The first terminal may receive the preservation message and determine whether to retain it, and may transmit the preservation message to the control server again (S280). If the control server receives the save message, the control server continuously stores the identification number of the first terminal and the other terminal in the database, receives the identification number of the first terminal from the other terminal, . On the other hand, if the control server receives the storage / non-storage message, the control server deletes the identification number of the first terminal and the other terminal from the database (S290). Accordingly, it is possible to reduce the psychological burden that the user of the first terminal can approach to a person having a different reason or affinity, and also to avoid date matching which is lost in the timelessness.

On the other hand, the application of the present invention is not limited to the object of the opponent who feels favorable, but may be the opponent having the objection. Accordingly, the present invention can also be used to determine whether another person dislikes himself or herself.

In addition, there are user terminals 501, 502, ..., 50n. The control server may be a subject performing the above-described series of steps, and the matching database may be a place where the control server stores the identification number received from the terminal. In addition, the backup database may be a place where the identification number deleted from the matching database is stored. The traffic management server can store all information about buses and traffic such as bus operation, location, route, and transmits the information according to the request of the control server. The wireless service control center server finally notifies the wireless AP maintenance manager when the control server finally determines that the wireless AP is defective and receives a request for the failure.

Meanwhile, the network between the control server, the radio navigation control center server, the traffic management server, and the wireless AP may be in various forms. In particular, the network may be composed of an LTE network. However, the network is not limited thereto.
