[Configuration of wireless communication terminal 1]
FIG. 2 is a diagram showing a configuration of a wireless communication terminal 1 according to the first embodiment.
The wireless communication terminal 1 includes an acceleration sensor 11, a GPS (Global Positioning System) receiver 12, a first communication unit 13, a second communication unit 14, a display unit 15, a storage unit 16, and a control unit 17. The control unit 17 includes a movement direction specifying unit 171, a history acquisition unit 172, a radio wave intensity specifying unit 173, a selection unit 174, and a tethering unit 175.

The acceleration sensor 11 detects the acceleration of the wireless communication terminal 1. The acceleration sensor 11 is, for example, a three-axis acceleration sensor that detects acceleration in three directions of the X-axis, the Y-axis, and the Z-axis. The acceleration sensor 11 transmits the detected information indicating the acceleration of the wireless communication terminal 1 to the moving direction specifying unit 171.

The GPS receiver 12 acquires the position of the GPS receiver 12, that is, the position of the wireless communication terminal 1 having the GPS receiver 12, by receiving and analyzing radio waves transmitted from a plurality of navigation satellites. The GPS receiver 12 transmits the acquired information indicating the position of the wireless communication terminal 1 to the moving direction specifying unit 171.

The display unit 15 is, for example, one or more of a plurality of other terminals 2 selected by the selection unit 174, which will be described later, that move in a direction within a predetermined range capable of maintaining communication with the moving wireless communication terminal 1. Information for identifying the other terminal 2 (for example, wireless terminal identification information) is displayed. The display unit 15 may display the wireless terminal identification information of the one or more other terminals 2 based on the priority order of the one or more other terminals 2 determined by the selection unit 174 described later, for example. The display unit 15 displays, for example, the wireless terminal identification information of another terminal 2 having a high probability of being able to communicate for a longer time with a high priority.

The storage unit 16 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 16 stores a program executed by the control unit 17.

The control unit 17 is, for example, a CPU (Central Processing Unit). By executing the program stored in the storage unit 16, the control unit 17 functions as a movement direction specifying unit 171, a history acquisition unit 172, a radio wave intensity specifying unit 173, a selection unit 174, and a tethering unit 175.

The movement direction specifying unit 171 specifies the first movement direction, which is the movement direction of the wireless communication terminal 1. The moving direction specifying unit 171 specifies the first moving direction of the wireless communication terminal 1 by receiving information indicating the acceleration of the wireless communication terminal 1 from the acceleration sensor 11, for example. The moving direction specifying unit 171 may specify the first moving direction based on the latitude / longitude information acquired from the GPS receiver 12. The movement direction specifying unit 171 notifies the selection unit 174 of information indicating the specified first moving direction.

The movement direction specifying unit 171 may specify the first moving direction based on the history of the position of the wireless communication terminal 1 acquired by the history acquisition unit 172. The movement direction specifying unit 171 specifies, for example, the same direction as the direction in which the position of the wireless communication terminal 1 has changed in the same time zone on the same day of the week in the past as the first movement direction.

In addition, the moving direction specifying unit 171 specifies the positions of a plurality of other terminals 2. The movement direction specifying unit 171 specifies a plurality of second movement directions, which are the movement directions of the plurality of other terminals 2, based on, for example, the history of the positions of the plurality of other terminals 2 acquired by the history acquisition unit 172. The movement direction specifying unit 171 specifies, for example, the same direction as the direction in which the positions of the plurality of other terminals 2 change in the same time zone on the same day of the week as the second movement direction. The movement direction specifying unit 171 notifies the selection unit 174 of information indicating the specified second moving direction.

The history acquisition unit 172 acquires the history of the positions of the plurality of other terminals 2 from the history management device 3 via the first communication unit 13. The history acquisition unit 172 notifies the movement direction specifying unit 171 of the acquired history of the positions of the plurality of other terminals 2.

The radio wave strength specifying unit 173 specifies the strength of radio waves received from each of the plurality of other terminals 2 via the second communication unit 14. The radio wave strength specifying unit 173 specifies the radio wave strength based on, for example, the RSSI signal output from the second communication unit 14. The radio wave strength specifying unit 173 notifies the selection unit 174 of the specified radio wave strength in association with the wireless terminal identification information of the other terminal 2.

The selection unit 174 moves in a direction within a predetermined range capable of maintaining communication with the wireless communication terminal 1 that moves in the first movement direction among the plurality of other terminals 2 that the wireless communication terminal 1 can communicate with. Select one or more other terminals 2. The selection unit 174 notifies the tethering unit 175 of information indicating the other terminal 2 which is the selected selection terminal.

Specifically, in the selection unit 174, the first movement direction of the wireless communication terminal 1 specified by the movement direction specifying unit 171 and the plurality of second moving directions of the plurality of other terminals 2 maintain communication, respectively. It is determined whether or not it is within a predetermined range. The selection unit 174 is a predetermined range capable of maintaining communication with the wireless communication terminal 1 moving in the first movement direction among the plurality of second movement directions specified by the movement direction specifying unit 171 for a predetermined time or longer. One or more other terminals 2 corresponding to the second moving direction in the above are selected. For example, the selection unit 174 selects another terminal 2 whose second moving direction is substantially the same as that of the first moving direction. The predetermined time is, for example, a time set by the user of the wireless communication terminal 1, and is one minute as an example.

The selection unit 174 may preferentially select another terminal 2 that is predicted to maintain a communicable state for a long time over another terminal 2 that is predicted to maintain a communicable state for a short time. good. In the case of the example shown in FIG. 1, the selection unit 174 preferentially selects the other terminal 2a and the other terminal 2d that are moving in the same direction. Even if the selection unit 174 preferentially selects another terminal 2 whose second moving direction is within a predetermined range with respect to the first moving direction and whose difference from the moving speed of the wireless communication terminal 1 is relatively small. good. When the selection unit 174 selects such another terminal 2, the probability that the wireless communication terminal 1 can communicate with the other terminal 2 for a long time increases.

The selection unit 174 may preferentially select the other terminal 2 having a high radio field strength of the other terminal 2 specified by the radio wave strength specifying unit 173 over the other terminal 2 having a low radio field strength. In the case of the example shown in FIG. 1, the selection unit 174 selects the other terminal 2d, which is closer and has a higher radio wave intensity, among the other terminal 2a and the other terminal 2d moving in the same direction.

The selection unit 174 selects one or more other terminals 2 in which the radio field intensity of the other terminal 2 specified by the radio wave intensity specifying unit 173 is included in the predetermined intensity range for a predetermined time or longer. May be good. In the selection unit 174, for example, the radio wave required for the wireless communication terminal 1 and the other terminal 2 to be separated from each other and the radio wave strength to be reduced to the level at which communication cannot be performed is longer than the communicable time set by the user. Select other terminal 2 of strength. As an example, the selection unit 174 is based on the movement speed of the wireless communication terminal 1, the movement speed of the other terminal 2 received from the other terminal 2, and the second movement direction of the other terminal 2 specified by the movement direction specifying unit 171. The time required for the distance between the wireless communication terminal 1 and the other terminal 2 to reach a distance at which communication becomes impossible is specified. By operating the selection unit 174 in this way, the probability that another terminal 2 that can maintain a good communication state for a longer time than the communicable time set by the user is selected increases.

The tethering unit 175 tethers using a selected terminal selected from one or more other terminals 2. The tethering unit 175 tethers by transmitting the data to be transmitted to the base station B to the selected terminal via the second communication unit 14. Specifically, the tethering unit 175 starts wireless communication with the selected terminal by the second wireless communication method, and accesses the Internet N via the selected terminal.

As described above, the wireless communication terminal 1 can maintain communication with the wireless communication terminal 1 that moves in the moving direction of the wireless communication terminal 1 among a plurality of other terminals 2 that the wireless communication terminal 1 can communicate with. Tethering is performed using a selection terminal that moves in a direction within a predetermined range. Therefore, the wireless communication terminal 1 is likely to exist in an area capable of communicating with the selected terminal that functions as an access point for tethering. As a result, the wireless communication terminal 1 is less likely to be disconnected when tethering is performed using the other terminal 2.

Further, as described above, the wireless communication terminal 1 has a movement direction for specifying a plurality of second movement directions of the plurality of other terminals 2 based on the history of the positions of the plurality of other terminals 2 acquired by the history acquisition unit 172. It has a specific part 171. The wireless communication terminal 1 selects the other terminal 2 having a high probability of moving in the same direction as the wireless communication terminal 1 by the movement direction specifying unit 171 specifying the second movement direction of the plurality of other terminals 2 in this way. It will be easier.
