Embodiment 1
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing a configuration of a radio communication system according to Embodiment 1 of the present invention. The wireless communication system 100 includes a mobile terminal 11, a communication tag 12, and a mid-range wireless communication device 13.

The mobile terminal 11 can be configured by a smartphone, a mobile phone terminal, or a PDA (Personal Data Assistance). The communication tag 12 performs short-range wireless communication with the mobile terminal 11. Here, “near field communication” is generally called NFC (Near field communication), and the communication distance is about several millimeters to 10 cm.

The mid-range wireless communication device 13 performs wireless communication with the mobile terminal 11. Here, “medium-range wireless communication” is communication having a longer communication distance than short-range wireless communication. Specifically, the communication distance is about several meters, and WiFi (Wireless Fidelity), Bluetooth (registered trademark), infrared communication, or the like can be used. In the following description, the medium-range wireless communication apparatus 13 is described as a WiFi (Wireless Fidelity) access point. In FIG. 1, the communication area of the medium-range wireless communication device 13 is shown as area 14.

As shown in FIG. 2, in the wireless communication system 100, the mobile terminal 11 enters a predetermined area 14 triggered by the user touching (contacting or almost touching) the mobile terminal 11 with the communication tag 12. Recognize that. The mobile terminal 11 that has recognized that it has entered the predetermined area 14 changes the operation mode from the normal operation mode to the specific operation mode corresponding to the area 14. Specifically, when the mobile terminal 11 is switched from the normal operation mode to the specific operation mode, the mobile terminal 11 starts an application corresponding to the specific operation mode. The portable terminal 11 performs middle-range wireless communication with the middle-range wireless communication device 13 installed in the area 14 under the changed specific operation mode. When the user leaves the area 14 and communication between the mobile terminal 11 and the medium-range wireless communication device 13 is interrupted, the mobile terminal 11 recognizes that the mobile terminal 11 has exited the area 14, ends the specific operation mode, and enters the normal operation mode. Transition.

Here, the “normal operation mode” is an operation mode outside the area 14 set in the mobile terminal 11, and the “specific operation mode” indicates a specific operation mode specialized for the area 14. To do. In the specific operation mode, an application that changes the type of application to be activated on the mobile terminal 11 is activated. Or in specific operation mode, the application which changes the kind and arrangement | positioning of the application displayed on the display part of the portable terminal 11 is started. In the specific operation mode, the communication method, radio wave intensity, and the like of the mobile terminal 11 are changed from those in the normal operation mode.

The communication tag 12 is installed in association with the area 14. Specifically, the communication tag 12 is associated with the area 14 by being installed inside the area 14 as shown in FIG. Yes. When the communication tag 12 is installed outside the area 14, the communication tag 12 may be arranged at a predetermined distance from the area 14 or the mid-range wireless communication device 13 installed in the area 14. For example, when the area 14 is present in an entire room, the communication tag 12 may be installed at the entrance of a room outside the area 14.

FIG. 3 is a diagram showing the configuration of the mobile terminal 11 of the wireless communication system 100 according to Embodiment 1 of the present invention. The mobile terminal 11 includes a short-range wireless communication unit 111, a medium-range wireless communication unit 112, and an operation mode switching unit 113. The short-range wireless communication unit 111, the medium-range wireless communication unit 112, and the operation mode switching unit 113 are realized by a CPU (Central Processing Unit) (not shown) of the mobile terminal 11 executing a predetermined program.

The near field communication unit 111 performs near field communication with the communication tag 12 installed in the predetermined area 14. The intermediate distance wireless communication unit 112 performs intermediate distance wireless communication with the intermediate distance wireless communication device 13. The operation mode switching unit 113 detects that the mobile terminal 11 has entered the area 14 by detecting that the short-range wireless communication unit 110 has performed short-range wireless communication with the communication tag 12. When the operation mode switching unit 113 detects that communication with the communication tag 12 is established, the operation mode switching unit 113 sets the operation mode to the specific operation mode using an application corresponding to the entered area 14. Specifically, a specific application corresponding to the specific operation mode is activated. And the portable terminal 11 performs middle distance radio | wireless communication with the middle distance radio | wireless communication apparatus 13 under specific operation mode.

Then, the operation mode switching unit 113 ends the specific operation mode when communication between the wireless communication unit 111 and the intermediate-range wireless communication device 13 becomes impossible due to the user leaving the intermediate-range wireless communication device 13. Return to normal operation mode. Specifically, the specific application is terminated and an application in a normal operation mode is activated. Note that the operation mode switching unit 113 ends the specific operation mode when a predetermined time elapses after a time during which communication between the wireless communication unit 111 and the intermediate-range wireless communication device 13 is impossible. May be.

The mobile terminal 11 switches to a specific operation mode corresponding to the area 14 by referring to a reference table as shown in FIG. In the reference table, a specific operation mode is associated with the combination of the ID of the medium-range wireless communication device 13 and the ID of the communication tag 12. In addition, when the intermediate-range wireless communication device 13 and the communication tag 12 correspond one-to-one, that is, when only one communication tag 12 is installed in the area 14 of the intermediate-range wireless communication device 13. The reference table may be configured by associating either the ID of the communication tag 12 or the ID of the medium-range wireless communication device 13 with information on the specific operation mode to be set. A plurality of communication tags 12 and medium-range wireless devices 13 are installed in the area 14, and each of the communication tags 12 and the medium-range wireless devices 13 are associated one-to-one. On the other hand, a reference table may be configured by associating information with respect to a specific operation mode.

The reference table can be configured to be held by the mobile terminal 11 itself so that the mobile terminal 11 can directly refer to the reference table. Alternatively, the mid-range wireless communication device 13 or an external server holds a reference table, and the portable terminal 11 transmits the received ID of the mid-range wireless communication device 13 and the ID of the communication tag 12, thereby enabling mid-range wireless. You may comprise so that the information regarding an operation mode may be acquired from the communication apparatus 13 or an external server. In addition, when the communication tag 12 holds a reference table and the mobile terminal 11 establishes a connection with the communication tag 12, the ID of the communication tag 12, the ID of the mid-range wireless device 13, and information regarding the operation mode are acquired. You may do it.

Note that the specific operation mode of this reference table can be freely set by the user for each communication tag 12. For example, the user can arbitrarily register the type and arrangement of applications to be displayed on the display unit for a certain communication tag 12. A plurality of setting information can be defined for one specific operation mode. Specifically, for a specific operation mode A, two or more setting information such as starting an application for displaying a television operation screen and displaying an application for accessing an external server that distributes movies is displayed. You can register. Moreover, you may comprise so that the various settings of the communication terminal 11 set for every specific operation mode may be downloaded to the portable terminal 11 from an external server previously.

Here, various settings of the mobile terminal 11 in the specific operation mode associated with the communication tag 12 can be freely set for each user. Specifically, a certain user can associate a specific operation mode A with one communication tag 12, and another user can associate a specific operation mode B with the same communication tag 12.

Next, the operation of the communication system configured as described above will be described. 5 and 6 are sequence charts showing the operation of radio communication system 100 according to Embodiment 1 of the present invention. The medium-range wireless communication device 13 periodically transmits its own identification information (ID: Identification) to the area 14 (step S1). When the mobile terminal 11 is located outside the area 14 that is the communication area of the medium-range wireless communication device 13, the mobile terminal 11 is set to the normal operation mode (step S2). In the normal operation mode, the mobile terminal 11 starts preparation for performing short-range wireless communication (step S3).

When the user enters the area 14 and the mobile terminal 11 moves to the area 14, the ID of the intermediate-range wireless communication device 13 periodically issued from the intermediate-range wireless communication device 13 is the intermediate-range wireless communication unit 112 of the mobile terminal 11. Received at. The operation mode switching unit 113 of the mobile terminal 11 detects that the mobile terminal 11 has entered the predetermined area 14 using the reception of the ID of the medium-range wireless communication device 13 as a trigger. Then, the wireless communication unit 111 starts access to the medium-range wireless communication device 13 (step S4). In addition, you may comprise so that the information which shows having entered the area 14 may be displayed on the display part of the portable terminal 11, and a user may be notified.

When the user touches the mobile terminal 11 on the communication tag 12, the communication tag 12 is activated (step S5). And the communication tag 12 transmits own ID to the portable terminal 11 by near field communication (step S6). The short-range wireless communication unit 111 of the mobile terminal 11 receives the ID from the communication tag 12 (step S7). The short-range wireless communication unit 111 that has received the ID outputs information indicating that short-range communication with the communication tag 12 has been performed to the operation mode switching unit 113. The operation mode switching unit 113 of the mobile terminal 11 refers to the reference table shown in FIG. 4 and searches for a specific operation mode associated with the combination of the ID of the medium-range wireless communication device 13 and the ID of the communication tag 12. (Step S8).

Note that in order to establish a connection between the mobile terminal 11 and the intermediate-range wireless communication device 13, the reception of the ID of the intermediate-range wireless communication device 13 as described above may not be used as a trigger. For example, when the user touches the communication tag 12 with the mobile terminal 11, the ID assigned to the communication tag 12 and the ID assigned to the medium-range wireless communication device 13 are transmitted to the mobile terminal 11 by short-range wireless communication. If the mobile terminal 11 receives only the ID of the communication tag 12 as a trigger, the connection between the intermediate-range wireless communication unit 112 of the mobile terminal 11 and the intermediate-range wireless communication device 13 may be established. good.

In step S8, when there is a specific operation mode associated with the combination of the ID of the medium-range wireless communication device 13 and the ID of the communication tag 12 (YES), the operation mode switching unit 113 changes the operation mode to the normal operation. The mode is shifted to the specific operation mode corresponding to the area 14 (step S9). Under the specific operation mode, the mobile terminal 11 performs data communication using the mid-range wireless communication device 13 in the area 14. On the other hand, if there is no specific operation mode associated with the combination of the ID of the medium-range wireless communication device 13 and the ID of the communication tag 12 in step S8 (NO), the process returns to step S7.

In the example of FIG. 5, the operation mode is configured to switch from the normal operation mode to the specific operation mode after the medium-range wireless communication is established. You may comprise so that communication may be started. In other words, when switching from the normal operation mode to the specific operation mode, the mid-range wireless communication may be started. And the portable terminal 11 continues medium-distance wireless communication under specific operation mode.

And the portable terminal 11 judges whether the portable terminal 11 remove | deviated from the area 14 of the medium distance radio | wireless communication apparatus 13 which performed communication (step S10). Specifically, it is determined whether or not the mobile terminal 11 is disconnected from the area 14 by detecting whether or not the data communication from the operation mode switching unit 113 and the intermediate-range wireless communication device 13 has been interrupted. In step S10, when the operation mode switching unit 113 determines that the mobile terminal 11 is out of the area 14 (YES), the operation mode is changed from the specific operation mode to the normal operation mode (step S11).

As described above, in the wireless communication system according to the first embodiment, the process of switching the operation mode is started using the operation of the user touching the communication tag 12 with the mobile terminal 11 as a trigger. Therefore, the operation mode can be switched by performing a simple operation only when the user intends. In other words, as in Patent Document 1, it is possible to prevent the operation mode from being switched without permission from the user.

In addition, when communication from the mid-range wireless communication device 13 is interrupted, the mobile terminal 11 determines that the mobile terminal 11 has left the area 14 and shifts from the specific operation mode to the normal operation mode. Thereby, the user can switch the operation mode to the normal operation mode by simply moving from the area 14 without performing any operation. Note that the mobile terminal 11 may be configured to be forcibly switched to the normal operation mode by a user operation even while the mobile terminal 11 is set to the specific operation mode.

Here, in the system disclosed in Patent Document 2, only one operation target such as a multifunction peripheral is associated with the communication tag. However, in the first embodiment, only one communication tag is touched. A plurality of applications for operating a plurality of operation targets can be activated or displayed. Further, in the system disclosed in Patent Document 2, the operation associated with the communication tag is limited to a specific one regardless of the user, but in the first embodiment, the reference as shown in FIG. The table can be set for each user, and the specific operation mode can be set for the communication tag for each user. Therefore, in the first embodiment, different users can set different specific operation modes using the same communication tag. Thereby, the freedom degree of selection of the specific operation mode for every user increases.

Next, a radio communication system according to Embodiment 2 of the present invention will be described. FIG. 7 shows a configuration of radio communication system 200 according to Embodiment 2 of the present invention. In the second embodiment, two

areas

142 and 143 are included in the communicable area 141 of the medium-range wireless communication device 131. In other words, in the second embodiment, areas exist hierarchically. The area 142 is an area where the medium-range wireless communication device 132 can communicate, and the area 143 is an area where the medium-range wireless communication device 133 can communicate. Communication tags 121, 122, and 123 are installed in the

areas

141, 142, and 143, respectively. The user can switch the operation mode of the mobile terminal 11 to a specific operation mode corresponding to each area by touching the mobile terminal 11 to any of the communication tags 121 to 123.

Note that the configurations of the mobile terminal 11, the communication tag 12, and the medium-range wireless communication device 13 are substantially the same as those in the first embodiment, and thus description thereof is omitted. The operation of the wireless communication system 200 is substantially the same as that of the first embodiment. Specifically, the operation mode switching unit 113 of the mobile terminal 11 refers to the reference table shown in FIG. The operation of the mobile terminal 11 in the specific operation mode associated with the combination of the IDs of the distance

wireless communication devices

131, 132, and 133 and the IDs of the communication tags 121, 122, and 123 with which the user touches the mobile terminal 11 Set the mode. Then, the mobile terminal 11 displays and activates a specific application corresponding to the specific operation mode, and communicates with the mid-range wireless communication device 13 under the specific operation mode. Then, when the user leaves the predetermined area, the operation mode of the mobile terminal 11 is switched from the specific operation mode to the normal operation mode.

Thus, in the wireless communication system 200 according to the second embodiment, for example, the area 141 of the medium-range wireless communication device 131 and the

areas

142 and 143 of the medium-range

wireless communication devices

132 and 133 overlap. Even if it is a case, the operation mode of the portable terminal 11 can be switched to a user's desired specific operation mode by identifying the communication tag 121,122,123 which the user touched.

In addition, when the operation mode set in the area 141 is different from the operation mode set in the

areas

142 and 143, when the user touches the communication tags 122 and 123 in the

areas

142 and 143, the mobile terminal 11 is The specific operation mode set in the area 141 is set, and the specific operation mode set in the

areas

142 and 143 is set. Here, if the specific operation mode set in the area 141 and the specific operation mode set in the

areas

142 and 143 cannot coexist, the operation mode in the

areas

142 and 143 is set with priority. can do. In this way, by setting the specific operation mode in a small area with priority, it is possible to set the specific operation mode more in line with the user's intention.

Embodiment 3 FIG.
FIG. 8 shows a configuration of radio communication system 300 according to Embodiment 3 of the present invention. In the third embodiment, as in the second embodiment,

areas

142 and 143 are included in the communicable area 141 of the medium-range wireless communication device 13. However, only the communication tags 122 and 123 are installed in the

areas

142 and 143, and no mid-range wireless communication device is provided. In other words, the

areas

142 and 143 do not indicate a communication area for each medium-range wireless communication device. As described above, even within the single communication area 141, by providing a plurality of

communication tags

122 and 123, the user can touch the mobile terminal 11 on any

communication tag

122 or 123, thereby enabling the communication tags 121 and 122. , 123 can be called a specific operation mode. In other words, a virtual area can be set by a plurality of

communication tags

121, 122, 123 even within one communication area 14. Note that the configurations and operations of the mobile terminal 11, the communication tags 121 to 123, and the medium-range wireless communication device 131 are substantially the same as those in the first embodiment, and thus description thereof is omitted.

Application example 1:
FIG. 9 is a diagram in which radio communication system 300 according to Embodiment 3 is applied to a radio communication system in an automobile. In the application example 1, one medium-range wireless communication device 13 is arranged in the automobile 50. An area in which the medium-range wireless communication device 13 can communicate is shown as 14. The area 14 is virtually divided into a front area (driver's seat side) and a rear area (rear seat side) of the automobile 50 by

communication tags

122 and 123. A communication tag 122 is installed on the driver's seat side in front of the automobile. In addition, a communication tag 123 is disposed on the rear seat side behind the automobile.

A user who has boarded the car 50 can set the operation mode of the mobile terminal 11 to the operation mode for the driver's seat by touching the communication tag 122 on the driver's seat side with the mobile terminal 11. On the other hand, the user can set the operation mode of the mobile terminal 11 to the operation mode for the rear seat by touching the communication tag 123 on the rear seat side with the mobile terminal 11. As described above, even within the single communication area 14, different operation modes can be set by using the two

communication tags

122 and 123.

FIG. 10 is a diagram showing a specific operation mode switching method in application example 1. FIG. The application example 1 is configured to change the type, combination, and arrangement of applications displayed on the display unit of the mobile terminal 11 when the operation mode is switched. In the normal operation mode, an icon (image) for starting an application such as the Internet, music, a call, mail, or a camera is displayed on the display unit of the mobile terminal 11. The combination and arrangement of icons may be set in the mobile terminal 11 by default or may be set in advance by the user.

Then, when the user touches the communication tag 122 on the driver's seat side with the mobile terminal 11, the operation mode shifts to a specific operation mode associated with the communication tag 122. Then, an application that preferentially displays icons (images) frequently used during driving such as car navigation (car navigation system), weather forecast, and music on the display unit is activated. Thereby, the display part of the portable terminal 11 switches to a display screen as shown in the upper right of FIG. When the user selects an icon of an application that the user wants to use, the mobile terminal 11 can communicate with the mid-range wireless communication device 13 using the activated application. Specifically, when the user selects an application such as a car navigation system, the mobile terminal 11 can function as a remote controller for a car navigation system separately installed in the car 50. In addition, when the user selects an application such as a car navigation system, the mobile terminal 11 communicates with the external server and the mid-range wireless communication device 13, and information acquired from the external server is displayed on a monitor installed in the car 50. You may comprise so that it may display.

On the other hand, when the user touches the communication tag 123 for the backseat of the portable terminal 11, the frequency of use by passengers other than the driver such as movies, TV, and town information associated with the communication tag 123 is used. An application that preferentially displays a high icon on the display unit is started. Thereby, the display part of the portable terminal 11 switches to a display screen as shown in the lower right of FIG. When the user selects an arbitrary application, the mobile terminal 11 activates the selected application and communicates with the medium-range wireless communication device 13 using the application. As described above, even in one automobile 50, by arranging a plurality of

communication tags

122 and 123, the operation mode of the mobile terminal 11 can be set to any specific operation by a simple operation that reflects the user's intention. Can be set to mode.

In the example of FIG. 10, the type of application to be displayed is changed when changing to the specific operation mode, but at least one of the type, arrangement, and display method of the application displayed on the display unit of the mobile terminal is changed. It can be configured to be. Here, the change of the display method includes changing the size of the icon or changing the display to a user-recognized display such as blinking.

FIG. 11 is a diagram illustrating another operation mode switching method of the application example 1. When the user touches the mobile terminal 11 on one of the communication tags 122 and 123 in the automobile 50, the mobile terminal 11 sets the radio field intensity for performing communication with the mobile terminal 11 to the medium-range wireless communication device that is the communication partner. The wireless strength according to 13 is set. Specifically, in the normal operation mode, it is assumed that the mobile terminal 11 is performing wireless communication with the base station 60 of the wide area communication network (3G, 4G) with a radio wave intensity of 100%. When the user touches the mobile terminal 11 on one of the communication tags 122 and 123, the radio wave intensity is changed to 5% and the radio wave intensity is changed. Thereby, the radio wave intensity of the mobile terminal 11 is set to a radio wave intensity that allows communication with the mid-range radio communication device 13 in the automobile 50.

Thus, for example, even when the automobile 50 is located in a wireless communication network such as 3G or 4G, the medium-range wireless communication device 13 can be preferentially communicated. In addition, power saving of the mobile terminal 11 can be achieved by suppressing the radio wave intensity.
