[Embodiment]
Hereinafter, embodiments of the communication system according to the present embodiment will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of the configuration of the communication system 100 of the present embodiment.

[Overall configuration of communication system 100]
The communication system 100 includes a plurality of terminal devices 10, a plurality of base stations 20, a network 30, and a communication status information management server 40.
The terminal device 10 of the present embodiment is, for example, a mobile phone or a smartphone. The terminal device 10 can be connected to, for example, a high-speed data communication line capable of transmitting and receiving audio information, image information, and moving image information on the same line. This high-speed data communication line is, for example, an LTE (Long Term Evolution) communication network. This high-speed data communication line provides, for example, a service (VoLTE; Voice over LTE) that enables voice calls in addition to transmission and reception of digital information such as images and characters.
The base station 20 performs communication with the terminal device 10 using the high-speed data communication line described above. When the terminal device 10 is located in the area AR, the base station 20 can perform communication with the terminal device 10 using a high-speed data communication line. Of the plurality of base stations 20, the base station 20-1 is in the area AR1, the base station 20-2 is in the area AR2, and the base station 20-3 is in the area AR3. Communication between them is possible. Further, the base station 20-4 can communicate with the terminal device 10 located in the area AR4, and the base station 20-5 can communicate with the terminal device 10 located in the area AR5.
The network 30 connects between the base stations 20 and between the base stations 20 and the communication status information management server 40.
The communication status information management server 40 communicates with the base station 20 via the network 30.
In the example of FIG. 1, among the plurality of terminal devices 10, the terminal device 10-1 and the terminal device 10-2 are located in the area AR4. Further, among the plurality of terminal devices 10, the terminal devices 10-3 are located in the area AR5. In the case of this example, the terminal device 10-1 and the terminal device 10-2 can communicate with the base station 20-4, and the terminal device 10-3 can communicate with the base station 20-5, respectively.
In the following description, when the terminal device 10-1 and the terminal device 10-2 ... Are generically referred to as the terminal device 10. Further, when the base station 20-1 and the base station 20-2 ... Are generically referred to, the base station 20 is described. Further, when the area AR1, the area AR2, and the like are collectively referred to, the area AR is described.

[Functional configuration of communication status information management server 40]
The communication status information management server 40 manages "communication status information" indicating the communication status between the terminal device 10 and the base station 20. The communication state between the terminal device 10 and the base station 20 changes depending on the situation. For example, when there is a shield between the terminal device 10 and the base station 20, the communication state may be worse than when there is no shield. Further, for example, when the number of terminal devices 10 in the area AR is large, the communication state may be worse than when the number of terminal devices 10 in the area is small. Further, for example, when the terminal device 10 moves from the area AR to another area AR, the communication state before the movement and the communication state after the movement may change.
The communication status information management server 40 manages the position of the terminal device 10 in association with the communication status between the terminal device 10 and the base station 20. A specific functional configuration of the communication state information management server 40 will be described with reference to FIG.

FIG. 2 is a diagram showing an example of the functional configuration of the terminal device 10 and the communication status information management server 40 of the present embodiment.
The communication status information management server 40 includes a control unit CS and a storage unit MS. The communication state acquisition information CQ1 is stored in advance in the storage unit MS. The communication state acquisition information CQ1 is information indicating a communication status between the base station 20 and the terminal device 10 located in the area AR of the base station 20. Indicators indicating this communication state include RSS (Received Signal Strength), C / I (interference wave ratio), Ec / Io (adjacent base station transmission level to current base station transmission level), and the like.
Further, the communication state prediction information CQ2 may be stored in advance in the storage unit MS. The communication state prediction information CQ2 is information indicating the prediction of the communication state of the terminal device 10 using the mobile communication network, and is the information indicating the prediction of the communication state at each position in the communication range. The communication state prediction information CQ2 is, for example, information that is predicted and generated based on the communication state acquisition information CQ1. Specifically, the base station 20 accumulates the communication state acquisition information CQ1 and performs statistical processing to generate the communication state prediction information CQ2. The communication status prediction information CQ2 includes communication status based on characteristics such as weekdays, holidays, time zones, weather, dates, seasons, information on events held in the vicinity, and the number of terminal devices 10 connected to the mobile communication network. The prediction of the communication state at each position of the mobile communication network is shown.
In the following description, when the communication status acquisition information CQ1 and the communication status prediction information CQ2 are not distinguished, they are collectively referred to as the communication status information CQ.

In this example, the communication status information CQ indicates the communication status (communication quality) by an index such as communication speed, communication ease of connection, and communication interruption difficulty. This index is divided into three stages, for example, "good", "OK", and "evil". In the case of this example, the communication status information CQ indicates the communication status in three stages of "good", "possible", and "bad".
Here, when the communication state information CQ indicates that the communication state is good (for example, when the communication state information CQ is “good”), the terminal device 10 has a large received signal strength and signal-to-interference noise. The ratio is large, the number of retransmissions is small, the data error rate is low, the throughput is high, or the number of terminal devices 10 connected to the mobile communication network is small. Further, when the communication state information CQ indicates that the communication state is poor (for example, when the communication state information CQ is "bad"), the received signal strength is low in the terminal device 10, and the signal-to-interference noise ratio. Is small, the number of retransmissions is large, the data error rate is high, the throughput is low, or the number of terminal devices 10 connected to the mobile communication network is large.
The communication state information CQ may be evaluated in more than 3 stages or in less than 3 stages instead of the configuration evaluated in 3 stages.

Further, the communication state information management server 40 may manage whether or not the communication state between the terminal device 10 and the base station 20 is the communication state required by the terminal device 10. Here, an example of the communication state required by the terminal device 10 will be described. The terminal device 10 can execute a plurality of application software. In the following description, "application software" is also simply referred to as "application".
Some of these applications have relatively low traffic and some have relatively high traffic. An example of an application with relatively low traffic is an e-mail application that exchanges textual information. An example of an application with a relatively large amount of communication is a video playback application that reproduces a moving image shared on the web.
When executing an application (for example, an e-mail application) having a relatively small amount of communication, the terminal device 10 can execute the application even in a relatively poor communication state without deteriorating the service quality. On the other hand, when the terminal device 10 executes an application having a relatively large amount of communication (for example, a moving image playback application), if the communication state is poor, frames may be dropped during moving image playback and the service quality may deteriorate. .. The terminal device 10 requests the communication state in stages such as "good" and "possible" according to the communication amount of the application.
Specifically, the terminal device 10 preferably has a “good” communication state when executing an application having a relatively large amount of communication. Further, when the terminal device 10 executes an application with a relatively small amount of communication, the communication state is preferably "good" or "possible".

Further, the communication status information management server 40 may manage statistical information such as a temporal transition of the number of connections of the terminal device 10 in the area AR of the base station 20 as the communication status information CQ.
In this case, the communication status information CQ is generated based on the current number of connections with the terminal device 10 in the area AR of the base station 20 and the number of past connections.
The communication status information management server 40 may acquire the communication status information CQ from the base station 20 or the communication status information CQ from the terminal device 10.

The control unit CS of the communication status information management server 40 includes a communication status information transmission unit 40a as its functional unit. The communication status information transmission unit 40a transmits the communication status information CQ to the terminal device 10. When the terminal device 10 requests the communication status information CQ, the communication status information transmission unit 40a transmits the communication status information CQ in response to the request of the terminal device 10.
In addition, the communication status information CQ may be stored in the storage unit MS in time series from the past to the present. In this case, the terminal device 10 may request the communication status information CQ at a required time point or a necessary period among the communication status information CQs stored in the storage unit MS. In this case, the communication status information management server 40 transmits the communication status information CQ at the time or period in response to the request of the terminal device 10 among the communication status information CQ stored in the storage unit MS to the terminal device 10. To do.

[Functional configuration of terminal device 10]
Next, an example of the functional configuration of the terminal device 10 will be described. In the example shown in FIG. 2, the terminal device 10 includes a control unit CT and a display unit DP. The display unit DP is a display device such as a display panel. The display unit DP displays information such as an image based on the control of the control unit CT.
The control unit CT includes a CPU, and includes a communication status information acquisition unit 10a, an application execution unit 10b, an application determination unit 10c, an application recommendation unit 10d, a movement determination unit 10e, and a communication status information display control unit 10f. And 10 g of a communication state information storage unit are provided as its functional unit.

The communication status information acquisition unit 10a acquires the communication status information CQ from the communication status information management server 40. The communication status information acquisition unit 10a acquires the communication status information CQ from the communication status information management server 40 at a predetermined timing. The predetermined timing includes a timing at which the application execution unit 10b starts executing the application, a timing at which the current position of the terminal device 10 changes, and the like.

The application execution unit 10b executes the application installed in the terminal device 10. This application includes an e-mail application and a moving image viewing application. As described above, the e-mail application is an example of an application having a relatively small amount of communication. The moving image viewing application is an example of an application having a relatively large amount of communication.

[Example of application type]
The following are examples of the types of applications executed by the application execution unit 10b.
(1) An application that requires both a large amount of communication and stability of communication conditions.
For example, in the case of streaming playback, the video playback application transmits / receives video data in real time during video playback. The video playback application is an example of an application that needs to stably maintain a state in which a relatively large amount of communication is performed during playback of an operation.
(2) An application in which a large amount of communication is required, but the stability of the communication state is relatively not required.
A download application for updating software functions is an example of an application in which a large amount of communication occurs for a relatively short time, although the amount of communication is relatively large.
When the communication state becomes unstable, the download application can reduce the communication speed of the download or interrupt the download. The download application differs from the video playback application in that the real-time performance required by the video playback application described above is not required.
(3) An application that requires stable communication status, although the amount of communication is relatively small.
In order to ensure a secure communication state, the electronic payment application may restart the payment process from the beginning if the communication is interrupted during the payment transaction. Such an electronic payment application is an example of an application in which a stable communication state is required, although a large amount of communication is relatively not required.

When the application execution unit 10b executes an application having a relatively large amount of communication, if the communication state at the current position of the terminal device 10 is relatively poor, the user may not be able to execute the application in a satisfactory state. For example, when the application execution unit 10b executes a moving image viewing application, if the communication state at the current position of the terminal device 10 is "evil", frame loss of the moving image occurs and the moving image is smoothly reproduced. It may not be possible.

As described above, the communication state between the terminal device 10 and the base station 20 changes depending on which area AR of the plurality of area ARs the terminal device 10 is in. For example, when a facility with a relatively high population density such as a railway station exists in the area AR, the number of terminal devices 10 connected to the base station 20 may increase depending on the time of day. In this case, the communication state of the area AR may be relatively worse than the communication state of the other area AR.
Further, the communication state between the terminal device 10 and the base station 20 also changes depending on where the current position of the terminal device 10 is in the area AR. For example, when the terminal device 10 is located inside the building, the communication state may be relatively poor as compared with the case where the terminal device 10 is located outside the building. That is, the communication state between the terminal device 10 and the base station 20 changes depending on the current position of the terminal device 10.

The application determination unit 10c determines whether or not each application installed in the terminal device 10 can be executed in a state in which the user is satisfied when the application execution unit 10b executes the application.
The application determination unit 10c determines based on the communication status information CQ acquired by the communication status information acquisition unit 10a. That is, the application determination unit 10c determines an application that can be executed by the application execution unit 10b based on the communication state information CQ.

The application recommendation unit 10d recommends an application determined by the application determination unit 10c that "the application execution unit 10b can execute" among the plurality of applications installed in the terminal device 10. Here, "recommending an application" includes displaying an application icon on the display unit DP and outputting sounds and vibrations associated with a specific application. That is, the application recommendation unit 10d presents the user of the terminal device 10 with an application recommended by images, sounds, vibrations, and the like.
Further, the term "the application execution unit 10b can execute" here includes not only that the application can be executed but also that the application can be executed in a good state. For example, in the case of a moving image playback application, the application can be executed in a good state when a communication environment of a predetermined speed or higher is continuously secured and the moving image is played back smoothly. In the case of this example, the application determination unit 10c determines that "the application execution unit 10b can execute" when a communication environment having a predetermined speed or higher can be continuously secured during the moving image reproduction period.

The movement determination unit 10e determines whether or not the terminal device 10 is moving. The movement determination unit 10e only needs to be able to determine the movement or stationary of the terminal device 10, and the means for detecting the movement or stationary is not limited. An example of the movement detection means by the movement determination unit 10e is shown.

[Example of movement detection means]
(1) Movement detection by GPS (Global Positioning System) The movement determination unit 10e obtains the position of the terminal device 10 by receiving the positioning radio wave from the GPS satellite, and the terminal device 10 moves depending on the presence or absence of this position change. Determine if it is inside. Further, the movement determination unit 10e determines whether or not the terminal device 10 is moving by receiving positioning radio waves from various positioning satellites such as the quasi-zenith satellites (QZS) in addition to the GPS satellite. May be determined.
(2) Movement Detection by Acceleration Sensor The movement determination unit 10e may include an acceleration sensor that detects the acceleration of the terminal device 10. In this case, the movement determination unit 10e determines whether or not the terminal device 10 is moving based on the detection result of the acceleration sensor. Further, when the detection result of the acceleration sensor indicates a specific acceleration pattern, the movement determination unit 10e may determine the movement means based on the acceleration pattern. For example, when the detection result of the acceleration sensor indicates an acceleration pattern that appears when moving on a railroad, the movement determination unit 10e may determine that the user of the terminal device 10 is moving by railroad. Further, when the detection result of the acceleration sensor indicates an acceleration pattern that appears when moving on foot, the movement determination unit 10e may determine that the user of the terminal device 10 is moving by walking.
Further, the movement determination unit 10e shows an acceleration pattern that appears when the user does not move and holds the terminal device 10 even when the acceleration sensor detects the acceleration. If so, it may be determined that the terminal device 10 is not moving.
(3) Movement detection based on area AR stay time The terminal device 10 has acquired an identifier (cell ID) of the area AR in the area from the base station 20. In this case, the movement determination unit 10e may determine whether or not the terminal device 10 is moving based on the presence or absence of a change in the cell ID. Specifically, the movement determination unit 10e determines that the terminal device 10 is not moving when the cell ID does not change for a predetermined time or more.
(4) Movement detection based on the short-range wireless connection state The terminal device 10 communicates with the short-range wireless access point in addition to the communication with the base station 20. In this case, the movement determination unit 10e can determine the position of the terminal device 10 by determining which of the plurality of access points can communicate with. In this case, the movement determination unit 10e determines that the terminal device 10 is moving when the access point capable of communicating changes.
(5) Determining whether or not the stationary state is continuous Further, the movement determination unit 10e not only determines whether or not the stationary state is currently present, but also determines whether or not the stationary state is continuing. You may. In this case, the movement determination unit 10e determines whether or not the stationary state continues based on the past movement status.

The communication status information display control unit 10f displays the communication status information CQ acquired by the communication status information acquisition unit 10a on the display unit DP.

The communication state information storage unit 10g stores the communication state information CQ acquired by the communication state information acquisition unit 10a. That is, the communication state information storage unit 10g stores the past communication state.

[Specific example of operation of control unit CT of terminal device 10]
FIG. 3 is a diagram showing an example of the operation of the control unit CT of the present embodiment.

(Step S1) The communication status information acquisition unit 10a acquires the communication status information CQ at the current position from the communication status information management server 40. The communication status information acquisition unit 10a acquires the communication status information CQ at a predetermined timing as shown below, for example.

[Communication status information CQ acquisition timing]
(1) Acquired when the terminal device 10 is moved.
The communication status information acquisition unit 10a acquires the communication status information CQ when the user of the terminal device 10 is moving. Specifically, the communication state information acquisition unit 10a acquires the movement determination result of the terminal device 10 from the movement determination unit 10e. The communication status information acquisition unit 10a sets the communication status information CQ when the acquired movement determination result changes from a state indicating that the terminal device 10 is stationary to a state indicating that the terminal device 10 is moving. get.
(2) Obtained when the application is started.
The communication status information acquisition unit 10a acquires the communication status information CQ when the application execution unit 10b starts the application. In this case, the application recommendation unit 10d presents to the user whether or not the started application is a "application to be recommended". Further, the application recommendation unit 10d may present to the user that the started application is a "non-recommended application" when the application other than the started application is a "recommended application". Good.
(3) Acquired when the reception frequency changes.
The terminal device 10 may be able to receive radio waves in a plurality of frequency bands. In this case, the communication status information acquisition unit 10a obtains the communication status information CQ based on which frequency band of the frequency bands that the terminal device 10 can receive is actually receiving radio waves. You may get it. For example, the communication status information acquisition unit 10a acquires the communication status information CQ when the frequency band of the received radio wave changes.
(4) Acquired when switching the communication frequency.
When the terminal device 10 can receive radio waves in a plurality of frequency bands, the communication state information acquisition unit 10a may acquire the communication state information CQ when the terminal device 10 changes the communication frequency band.
(5) Acquired when communication is restored after communication blackout.
The communication status information acquisition unit 10a may acquire the communication status information CQ at the timing when the communication status is improved and the communication is restored when the communication status is deteriorated and the communication is interrupted.

(Step S2) The application determination unit 10c determines an application that can be executed at the current position of the terminal device 10. As an example, the application determination unit 10c determines an executable application based on the determination condition list shown in FIG.

FIG. 4 is a diagram showing an example of a determination condition list used for determination by the application determination unit 10c of the present embodiment. This determination condition list is stored in a storage unit (not shown) of the terminal device 10. In this storage unit, the application name and the communication state required for the application are associated with each other and stored as a determination condition list. Specifically, in the determination condition list, the "video playback" application is associated with the communication volume "good" or higher and the stability "good" or higher. Further, in the judgment condition list, the "download" application is associated with the communication volume "good" or higher and the stability "possible" or higher. Further, in the judgment condition list, the "electronic payment" application is associated with the communication volume "bad" or higher and the stability "good" or higher.

[Example of judgment by application judgment unit 10c]
The application determination unit 10c compares the communication status information CQ with the determination condition list, and determines an executable application.
(1) When the communication status information CQ indicates the communication volume "good" and the stability "good" The application determination unit 10c executes any of the "video playback" application, the "download" application, and the "electronic payment" application. Judge that it is possible.
(2) When the communication status information CQ indicates a communication amount of "good" and stability of "possible" The application determination unit 10c determines that the "download" application and the "electronic payment" application can be executed.
(3) When the communication status information CQ indicates the communication volume "bad" and the stability "good" The application determination unit 10c determines that the "electronic payment" application can be executed.

(Step S3) The application recommendation unit 10d recommends an application determined by the application determination unit 10c to be executable at the current position of the terminal device 10.

[Example of recommended application]
An example of the application recommended by the application recommendation unit 10d is shown below.
(1) Recommend all executable applications.
The application recommendation unit 10d recommends all applications that the application determination unit 10c has determined to be executable at the current position of the terminal device 10. For example, in the above example, when the application determination unit 10c determines that any of the "video playback" application, the "download" application, and the "electronic payment" application can be executed, these three applications are recommended.
(2) Of the executable applications, the one with the higher required communication status is recommended.
The application recommendation unit 10d may recommend the one with the higher required communication state among the executable applications. For example, in the above example, when the application determination unit 10c determines that any of the "video playback" application, the "download" application, and the "electronic payment" application can be executed, the application recommendation unit 10d is requested. We recommend the "video playback" application with the highest communication status.
Here, when the application recommendation unit 10d recommends an application regardless of the required communication state, a situation arises in which an application with a low required communication state (that is, an application with low specifications) is always recommended. sell. The application recommendation unit 10d can prevent an application having low specifications from being always recommended by recommending the application having the higher required communication state.
(3) Recommend applications that are frequently executed.
The application recommendation unit 10d may recommend an executable application that is frequently executed by the user. For example, in the above example, among the "video playback" application, the "download" application, and the "electronic payment" application, the execution frequency of the "electronic payment" application may be higher than the execution frequency of the other application. In this case, when the application determination unit 10c determines that any of the "video playback" application, the "download" application, and the "electronic payment" application can be executed, the application recommendation unit 10d has the highest execution frequency of the "electronic". Recommend the "Payment" application.

[Example of timing to recommend an application]
An example of the timing at which the application recommendation unit 10d recommends an application is shown below.
(1) Recommended when moving the terminal device 10.
The application recommendation unit 10d recommends an application when the movement determination unit 10e determines that the terminal device 10 is moving. In this case, the application recommendation unit 10d may select the recommended application according to the means of transportation. For example, the application recommendation unit 10d may change the recommended application depending on whether the movement is by walking or by rail. Further, when it is determined that the user of the terminal device 10 holds the terminal device 10 by hand, the application recommendation unit 10d may recommend the application.
(2) Recommended when starting the application.
The application recommendation unit 10d may recommend when the application is started. In this case, the application recommendation unit 10d may recommend each time any of the applications installed in the terminal device 10 is started, or recommends when a specific application is started. May be good.
(3) Recommended when communication is restored after communication blackout.
The application recommendation unit 10d may recommend an application at the timing when the communication condition is improved and the communication is restored when the communication condition is deteriorated and the communication is interrupted. Further, in this case, the application recommendation unit 10d may recommend this application if the application that was executed when the communication state becomes poor and the communication is interrupted can be executed after the communication is restored.
In addition, if the execution is interrupted during the execution of the application, the interruption history may be acquired. The cause of the interruption may be recorded in this interruption history. The application recommendation unit 10d may recommend this application when the cause of the interruption is "communication interruption due to deterioration of the communication state" and the communication state is restored to a state in which the interrupted application can be executed. ..
Further, the application recommendation unit 10d may recommend an application when the electric field level of the radio wave received by the terminal device 10 is no longer 0 (zero).
(4) Recommended when operated by the user.
The application recommendation unit 10d may recommend an application when the terminal device 10 is turned on, that is, when it is started. Further, the application recommendation unit 10d recommends an application when the state of not being displayed on the display unit DP of the terminal device 10 (blackout state) changes to the state of being displayed on the display unit DP. You may.
Further, the application recommendation unit 10d may recommend an application when it detects that the screen of the terminal device 10 is unlocked or when it detects that the charging cable is inserted or removed.

In addition, when the application recommendation unit 10d recommends an application, when the user selects this application, the application recommendation unit 10d may not recommend the application having the selection history by the user at the subsequent recommendation timing.
Further, when the application recommendation unit 10d recommends the application, the application may not be recommended at the subsequent recommendation timing regardless of whether or not the user selects the application.
Further, when the application recommendation unit 10d recommends the application, if the user does not select the application, the application recommendation unit 10d may recommend the application again at the subsequent recommendation timing.
Further, when the application recommendation unit 10d recommends the same application again at a subsequent recommendation timing after recommending the application, the application recommendation interval may be set for a predetermined period.

(Step S4) The application execution unit 10b executes the application based on the user's operation.

[Example of screen display]
Next, an example of screen display on the display unit DP by the communication status information display control unit 10f will be described.

(1) When traveling by train (map display)
FIG. 5 is a diagram showing an example of a map display by the communication state information display control unit 10f of the present embodiment. The communication status information display control unit 10f displays the communication status of the peripheral area including the current position of the terminal device 10 on the map. In the example of the figure, the current position of the terminal device 10 is station A. In this case, the communication status information display control unit 10f displays the communication status of the area AR1 including the A station and the areas AR2 and AR3 which are the peripheral areas of the area AR1. Here, the area AR2 is an area including the B station.

When the movement determination unit 10e determines that the terminal device 10 is moving, the communication status information display control unit 10f displays the map shown in the figure.
When the user of the terminal device 10 looks at the display screen shown in the figure while moving from the A station to the B station, it can be seen that the communication state of the B station is better than that of the A station. In this case, the user of the terminal device 10 can determine that it is better to execute the application at station B than to execute the application at station A.
That is, the communication status information display control unit 10f can notify the user at which position on the map the application should be executed by displaying the communication status on a map.
Further, in this case, the application recommendation unit 10d may recommend an application that cannot be executed at the A station but can be executed at the B station.
The movement determination unit 10e may determine that the terminal device 10 is moving based on the position change history even when the current position of the terminal device 10 has not changed. For example, the movement determination unit 10e determines that the terminal device 10 is moving when the terminal device 10 has moved to just before. In this case, the communication state information display control unit 10f performs the above-mentioned map display even when the current position of the terminal device 10 has not changed.

Further, when the communication state information display control unit 10f has an area in the middle of the movement route where the communication state is poor and the communication is likely to be interrupted, the area may be displayed on the map. By displaying the area where communication is likely to be interrupted (interruption area) on a map in this way, the communication status information display control unit 10f warns the user who passes through the interruption area that the application cannot be executed. Can be done.
Further, when the interruption area exists on the movement route, the application recommendation unit 10d may select the application to be recommended based on the time required to reach the interruption area. For example, when it is predicted that the user will move and reach the interruption area 10 minutes later, the application recommendation unit 10d recommends an application having an average execution time of 10 minutes or less among the executable applications. That is, the application recommendation unit 10d recommends the application based on the execution result (statistical information) of the past application. In this case, the application recommendation unit 10d may calculate the time required to reach the interruption area based on the moving speed of the user.

Further, the communication state information display control unit 10f may change the scale of the map displayed on the display unit DP according to the moving speed of the user. In the case of this example, the communication status information display control unit 10f displays a rough map over a wide range when the moving speed of the user is relatively fast, and a detailed map over a narrow range when the moving speed of the user is relatively slow. , Display each.

(2) When stationary (display of time series information)
FIG. 6 is a diagram showing another example by the communication state information display control unit 10f of the present embodiment. The communication status information display control unit 10f displays a time-series communication status at the current position of the terminal device 10. The communication status information display control unit 10f displays the communication status (estimated value) after the current time (time 7:00 in the example of the figure) on the display unit DP. The estimated value of this communication state is estimated based on the past communication state in each area of the base station 20. For example, the estimated value of the communication state is obtained by averaging the past communication states at the same time and the same day of the week at the same point. That is, the communication status information display control unit 10f displays the communication status after the current time, which is estimated based on the statistical information, in the display unit DP in chronological order.

As a result, the user of the terminal device 10 can know which time zone is good for executing the application. For example, as shown in the figure, if the communication status of the terminal device 10 is "bad" at the current time (7:00), the communication status becomes "possible" if the communication status is waited until 8:00 one hour later. I understand that. In this case, the user can determine that the application that can be executed when "OK" should be executed after waiting for one hour instead of executing at the current time. Further, the user of the terminal device 10 knows that when the communication status at the current time (7:00) is "bad", the communication status becomes "good" if he / she waits until 11:00 four hours later. In this case, the user can determine that the application that can be executed in the case of "good" cannot be executed without waiting for 4 hours. Further, in this case, the user can decide whether to wait until 11:00 or move to another place.

The communication status information display control unit 10f may display a button image for switching between the map display and the time series display on the display unit DP. As a result, the communication state information display control unit 10f can present the map image to the user by the operation of the user even if the user is not moving. As a result, the user of the terminal device 10 can know which area AR to move to when it is determined that the location should be moved to execute the application.

Further, the communication state information display control unit 10f may display not only the estimated value of the communication state (that is, the future communication state) but also the past communication state (that is, the actually measured value of the communication state). As a result, the user of the terminal device 10 can refer to the actually measured value more accurately than the estimated value when executing the application at the same place the next day, for example.
