Description

  The present invention relates to a wireless communication device, an area information providing device, a system, a method, and a program.

  The user of the wireless communication terminal can determine whether the wireless communication terminal is within the wireless communication service area based on signal strength information displayed on the wireless communication terminal or the like.

  However, it is difficult for the user to know in advance whether the destination of the wireless communication terminal is within or outside the service area. Therefore, the user knows that he / she has moved out of the service area because communication is not possible at the destination.

  In particular, when moving in an area (for example, a mountain area or the sea) where the number of base stations for wireless communication is small, the wireless communication terminal becomes unable to communicate by moving out of the service area without the user's knowledge. May be lost.

  On the other hand, in the method described in Patent Literature 1, the current position and the radio wave state of the vehicle are transmitted from the vehicle to the center.

[Second embodiment]
Next, a second embodiment of the present invention will be described. In the present embodiment, the wireless communication device 10 will be described more specifically.

  First, FIG. 3 shows a configuration example of the wireless communication system of the present embodiment. The wireless communication system according to the present embodiment includes an area information providing device 50 and wireless communication devices 10 (10A to 10C).

  The wireless communication device 10 is a device that performs wireless communication. For example, a mobile phone terminal owned by an individual, a wireless communication device mounted on an aircraft or a ship, and the like correspond to the wireless communication device 10. The area information providing device 50 is a device that provides the wireless communication device 10 with area information indicating an area where wireless communication is possible. One or more wireless communication devices 10 can exist in a wireless communication system. Also, one or more area information providing devices 50 can exist in the wireless communication system. When a plurality of area information providing apparatuses 50 exist in the wireless communication system, for example, each of the area information providing apparatuses 50 may be in charge of a different wireless communication scheme, a used frequency band, and the like.

  Next, FIG. 4 shows a configuration example of the area information providing device 50 of the present embodiment. The area information providing device 50 of the present embodiment includes a communication information receiving unit 51, an area information generating unit 52, and an area information transmitting unit 53.

  The communication information receiving unit 51 receives communication quality of wireless communication and position information of the wireless communication device 10 from the wireless communication devices 10 (10A to 10C). The area information generating unit 52 generates area information indicating an area where wireless communication is possible, based on the communication quality and the position information of one or more wireless communication devices 10. The area information transmitting unit 53 transmits the generated area information to the wireless communication device 10.

  The area information generation unit 52 plots the area information by plotting the communication quality on a coordinate axis or a map based on the communication quality and position information of one or more wireless communication devices 10 received in a past predetermined period, for example. Can be generated. The area information to be generated may be map information or position information indicating a boundary between an area where wireless communication is possible and an area where wireless communication is not possible. Alternatively, out-of-service information may be generated by the method described in Patent Literature 1, and an area that is not out of service may be set as an area where wireless communication is possible.

  Next, a configuration example of the wireless communication device 10 according to the present embodiment will be described with reference to FIG.

  The wireless communication unit 11 performs wireless communication. An arbitrary method such as 3G (3rd Generation), LTE (Long Term Evolution), and 5G (5th Generation) can be used as the wireless communication method.

  The communication information transmitting unit 12 transmits the communication quality of wireless communication and the position information of the own device to the area information providing device 50 via the wireless communication unit 11. The communication information transmitting unit 12 transmits the communication quality and the position information at predetermined timing such as at predetermined time intervals. The communication information transmitting unit 12 may further transmit the information on the wireless communication system, the information on the used frequency band, the information on CA (Carrier Aggregation), and the like to the area information providing device 50. By doing so, the area information providing apparatus 50 can generate area information according to the wireless communication method, the used frequency band, the CA status, and the like, and transmit the area information to the wireless communication apparatus 10.

  The communication information transmitting unit 12 can acquire the communication quality of the wireless communication from the wireless communication unit 11. The communication quality includes, for example, radio wave reception level, received signal strength, RSCP (Received Signal Coded Power), RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), and CN (Carrier to Noise) ratio. Alternatively, the communication quality may be the number of antenna pictograms displayed on the wireless communication device 10, the communication speed, the throughput, the latency, and the like.

  Further, the communication information transmitting unit 12 can acquire the position information of the wireless communication device 10 using a satellite positioning system such as a GNSS (Global Navigation Satellite System). Alternatively, the communication information transmitting unit 12 can perform positioning using RTT (Round Trip Time). The positioning based on the RTT is a method of performing the positioning based on the RTT between the wireless communication base station and the wireless communication device 10 and the position of the wireless communication base station. For example, Wi-Fi (registered trademark) positioning or the like corresponds to positioning by RTT, but a wireless communication method that can be used for positioning is not limited to Wi-Fi. The position information acquired by the communication information transmitting unit 12 is, for example, latitude and longitude, altitude, altitude, geoid information, and the like.

  The communication information receiving unit 51 of the area information providing device 50 generates area information indicating an area where wireless communication is possible, based on the communication quality and the position information transmitted by the communication information transmitting unit 12 of the wireless communication device 10.

  The area information receiving unit 13 receives area information indicating an area where wireless communication is possible from the area information providing device 50 via the wireless communication unit 11. The area information may further include a value of an index indicating communication quality (for example, a value of a received electric field strength), information on a communication method capable of performing communication, information on CA, and the like. Further, the area information receiving unit 13 may further receive terrain information such as altitude (geoid) and latitude and longitude. The area information receiving unit 13 receives the area information at a predetermined timing such as every predetermined time or when requested by the user. Note that the area information received from the area information providing device 50 may be information within a predetermined range (for example, within a radius of several kilometers) from the current position of the wireless communication device 10.

  The area map updating unit 14 causes the area map storage unit 15 to store an area map in which the area information and the communication quality of the own device are reflected on the geographical condition indicating the information of the place where the vehicle can pass. More specifically, the area map updating unit 14 reflects the area information and the communication quality of the own device in the area map stored in the area map storage unit 15. When the wireless communication is not possible, the area information receiving unit 13 cannot receive the area information. Therefore, the area map updating unit 14 reflects the communication quality of the own device in the area map stored in the area map storage unit 15. Let it. As a result, the area map stored in the area map storage unit 15 reflects the area information and the communication quality of the own device in the geographical condition indicating the information of the place where the vehicle can pass.

  The geographical condition is information indicating a place where the vehicle can pass. For example, the information includes map data of a general car navigation system, information indicating a place where traffic can be performed by walking, cycling, public transportation, and the like. In the case of a sea, information indicating a sea area where traffic can be performed. The wireless communication device 10 may hold the geographical conditions in advance or may receive the geographical conditions from the area information providing device 50.

  Further, as shown in FIG. 5, the wireless communication device 20 may include a geographical condition input unit 27, and the geographical condition input unit 27 may receive an input of a geographical condition from a user. The user can, for example, pass through the map data held by the wireless communication device 20, but in fact, use geographical conditions to obtain information on places that cannot be passed due to a collapse, a bridge outflow, a road depression, or the like. Can be input to the geographical condition input unit 27. In addition, for example, the user inputs information of a traversable road such as a beast road, a private road, or a local through road which is not in the map data held by the wireless communication device 20 as a geographical condition. It can be input to the unit 27.

  In this case, the geographic condition input unit 27 may transmit the geographic condition input by the geographic condition input unit 27 to the area information providing device 50 via the wireless communication unit 11. Further, the area information receiving unit 13 may receive the geographical condition input by the user of another wireless communication device 20 from the area information providing device 50 via the wireless communication unit 11.

  The route information output unit 16 extracts and outputs a first route from the current position of the wireless communication device 10 to a first destination included in an area where wireless communication is possible, based on the area map. When the wireless communication unit 11 attempts to perform wireless communication and cannot perform wireless communication, or when requested by a user, the route information output unit 16 transmits the route information from the current position of the wireless communication device 10 to the first destination. The first path is extracted and output.

  The route information output unit 16 may extract the first route when wireless communication is not possible. The route information output unit 16 determines whether wireless communication is possible or not based on whether wireless communication is possible when the wireless communication unit 11 attempts wireless communication, or whether wireless communication is possible using an area map stored in the area map storage unit 15. Can be determined.

  The first route output method includes, for example, displaying route information on a map displayed on the screen of the wireless communication device 10, outputting sound to a speaker or the like, outputting to another device outside the wireless communication device 10, and the like. Any method can be used.

  In addition, the route information output unit 16 can set, for example, a point included in an area where wireless communication is possible and having a shorter distance of the first route as a first destination of the first route. . Alternatively, the route information output unit 16 may set, as the first destination, a point included in an area where wireless communication is possible and having a shorter linear distance from the current position of the wireless communication device 10.

  Alternatively, the area information receiving unit 13 receives the area information including the information of the position where the other wireless communication device 10 is present, and the route information output unit 16 includes The point where the communication device 10 exists may be set as the first destination. However, in this case, since the wireless communication device 10 cannot perform wireless communication, if a long time has elapsed since the wireless communication was disabled, there is a possibility that another wireless communication device 10 has already moved. is there. Therefore, when outputting the extracted first route, the wireless communication device 10 also outputs information on the time at which the other wireless communication device 10 was present at the point, and the like, so that the user may be able to move. It is good to be able to grasp.

  Alternatively, the route information output unit 16 may extract the first route according to the weather information on the weather. For example, the route information output unit 16 determines a point included in an area where wireless communication is possible and having relatively good weather, for example, a point with a small amount of rainfall or a point where the weather is expected to recover, as a first destination. It is good. Alternatively, the route information output unit 16 may extract a first route with relatively good weather. In this case, the area information receiving unit 13 may receive the area information including the weather information from the area information providing apparatus 50, or may receive the area information including the weather information from the wireless communication apparatus 10 or the weather information providing apparatus other than the area information providing apparatus 50. May be received. Alternatively, the wireless communication device 10 may have a weather information acquisition function such as a barometer, and the route information output unit 16 may use the weather information acquired by the weather information acquisition function.

  Further, the route information output unit 16 may extract the first route according to the personal profile. The personal profile includes, for example, age, gender, physique, physical strength information, and biological information such as heart rate, maximum heart rate, blood pressure, blood oxygen concentration, lactate value, and hydration / dehydration level. As shown in FIG. 6, the wireless communication device 30 may include a personal profile input unit 38, and the personal profile input unit 38 may receive a personal profile input from a user. Alternatively, the personal profile input unit 38 may receive biological information from a biological information measuring device inside or outside the wireless communication device 30.

  For a person with no physical strength or a person who is tired, a path with a small height difference may be more desirable even if the moving distance is slightly longer. Therefore, the route information output unit 16 may extract and output one or more first routes (a route with a short moving distance, a route with a small height difference, and the like) according to the personal profile. At this time, the route information output unit 16 may output information on the degree of difficulty of each first route together with information on the first route.

  The route information output unit 16 can output one or more first routes extracted by one or more methods described above.

  The route information output unit 16 may output an estimated required time to the first destination as additional information of the first route. The estimated required time can be calculated based on the distance and the moving speed of the first route.

  Further, the route information output unit 16 may calculate a desired required time based on the weather information, and output the calculated desired required time. For example, the route information output unit 16 provides the user with the time required until the weather deteriorates as a desired required time, so that the user can select the first route that can be reached before the weather deteriorates. Become. The route information output unit 16 may calculate the desired required time based on the remaining battery capacity of the wireless communication device 10. For example, the route information output unit 16 provides the user with the time until the remaining battery capacity reaches the predetermined ratio as a desired required time, so that the user can arrive before the remaining battery capacity reaches the predetermined ratio. One route can be selected.

  By configuring the wireless communication apparatus 10 in this manner, the wireless communication apparatus 10 transmits the communication quality of wireless communication and the position information of the wireless communication apparatus 10 to the area information providing apparatus, and transmits area information indicating an area where wireless communication is possible. Is received from the area information providing device. Then, based on the area map in which the geographical conditions reflect the area information and the communication quality of the own device, the wireless communication device 10 includes the first destination included in the area where wireless communication is possible from the current position of the own device. The first path is extracted and output. Therefore, it is possible to provide the user with a moving route to a point where wireless communication is possible.
