SUMMARY OF THE INVENTION
However, the user cannot know which application is to be restricted even when restriction processing on per application basis is being carried out. Thus, there has been a problem that the user cannot easily recognize which application is to be restricted, specifically the user can recognize that an application is restricted only after trying to use the application.
Thus, the present invention has been made in view of the above-mentioned problem, and an objective thereof is to provide a mobile station capable of easily informing the user of applications to be restricted when restriction processing on per application basis is carried out.
A first feature of the present invention is summarized as a mobile station including: a storage unit configured to store an application executable on the mobile station; a display unit configured to display an icon for the application on a display; and a determination unit configured to determine an application to be restricted based on restriction information. Here, the display unit is configured to change a display method of displaying the icon for the application executable on the mobile station on the display based on a result of the determination on the application to be restricted.

MODE FOR CARRYING OUT THE INVENTION
Mobile Communication System According to First Embodiment of Present Invention
A mobile communication system according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4. This embodiment will be described by taking a mobile communication system of an LTE scheme as an example of the mobile communication system according to this embodiment. However, the present invention is applicable to mobile communication systems other than that of an LIE scheme.
As shown in FIG. 1, the mobile communication system according to this embodiment includes a radio base station eNB and a mobile station UE.
Here, in the mobile communication system according to this embodiment, the radio base station eNB is configured to be capable of sending the mobile station UE SSAC information which is restriction information for carrying out SSAC and ACDC information which is restriction information for carrying out ACDC.
For example, SSAC information is restriction information for carrying out restriction processing on per MS (IP Multimedia Subsystem)-level service basis. Note that such an IMS-level service is assumed to be an IMS-Voice (e.g., VoLTE: Voice over LTE) service, an IMS-Video (e.g., a TV telephone) service, or the like.
The mobile station UE according to this embodiment is a mobile station UE called a “smartphone,” for example. As shown in FIG. 2, the mobile station UE includes a reception unit 11, a determination unit 12, a storage unit 13, and a display unit 14.
The reception unit 11 is configured to receive various signals from the radio base station eNB. For example, the reception unit 11 is configured to receive restriction information such as SSAC information and ACDC information from the radio base station eNB. Such various signals may be sent via broadcast information, or may be sent via dedicated control signals.
The determination unit 12 is configured to determine an application to be restricted based on restriction information such as SSAC information or ACDC information.
For example, the determination unit 12 may be configured to determine, when the reception unit 11 receives SSAC information, that an application which handles a service (e.g., an IMS-Voice (VoLTE) service) restricted according to the SSAC information sent via broadcast information (e.g., an application for calls) is an application to be restricted and that other services (e.g., an application for mails and an application for disaster message board) are applications other than applications to be restricted.
Alternatively, the determination unit 12 may be configured to determine, when the reception unit 11 receives ACDC information, that an application which is rated as the rank of applications restricted according to the ACDC information (e.g., Skype) is an application to be restricted and that other services (e.g., an application for VoLTE service) are applications other than applications to be restricted.
The storage unit 13 is configured to store applications executable on the mobile station UE. To be more specific, the storage unit 13 is configured to store applications installed in the mobile station UE.
In addition, the storage unit 13 may be configured to store an application already set in the mobile station UE but not yet installed in the mobile station UE.
Further, the storage unit 13 may be configured to store, if any, an application which can replace each application.
As shown in FIG. 3(a), the display unit 14 is configured to display, on a display 14A, icons 140 to 151 for applications executable on the mobile station UE.
Here, the display unit 14 may be configured to decide applications, whose corresponding icons 140 to 151 should be displayed on the display 14A, according to the setting made by a user. To be more specific, the display unit 14 may be configured to display, on the display 14A, only the icons 140 to 151 for applications set by the user.
In addition, as shown in FIGS. 3(b) and 3(c), the display unit 14 is configured to use different display methods between icons 141, 143 to 145, 147, and 149 to 151 for applications to be restricted and icons 140, 142, 146, and 148 for applications other than the applications to be restricted.
Here, the display unit 14 may be configured to change at least one of the color, size, shape, icon display mode, and display location of each of the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted.
Incidentally, the display mode includes motions such as the blinking, rotation, and fadeout of an icon.
For example, as shown in FIG. 3(b), the display unit 14 may be configured to change the color of each of the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted to “black.”
In addition, as shown in FIG. 3(c), the display unit 14 may be configured not to display the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted.
Further, the display unit 14 may be configured to make the size of each of the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted smaller than the icons 140, 142, 146, and 148 for the applications other than the applications to be restricted.
Furthermore, the display unit 14 may be configured to change the display location of each of the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted to a location below (or above) the display location of each of the icons 140, 142, 146, and 148 for the applications other than the applications to be restricted.
Alternatively, the display unit 14 may be configured to change at least one of the color, size, and display location of each of the icons 140, 142, 146, and 148 for the applications other than the applications to be restricted.
For example, the display unit 14 may be configured to change the color of each of the icons 140, 142, 146, and 148 for the applications other than the applications to be restricted to “red.”
Further, the display unit 14 may be configured to make the size of each of the icons 140, 142, 146, and 148 for the applications other than the applications to be restricted larger than the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted.
Furthermore, the display unit 14 may be configured to change the display location of each of the icons 140, 142, 146, and 148 for the applications other than the applications to be restricted to a location above (or below) the display location of each of the icons 141, 143 to 145, 147, and 149 to 151 for the applications to be restricted.
Besides, the display unit 14 may be configured to display the restriction rate included in the SSAC information or the ACDC information.
Alternatively, the display unit 14 may be configured to change at least one of the color, size, shape, icon display mode, and display location of each of the icons for the applications to be restricted based on the restriction rate included in the SSAC information or the ACDC information, instead of directly displaying the restriction rate included in the SSAC information or the ACDC information.
Further, the display unit 14 may be configured to display, on the display 14A, information that prompts use of an application which can replace each of the applications to be restricted.
Alternatively, the display unit 14 may be configured to make a voice notice or a text notice of information that prompts use of an application which can replace each of the applications to be restricted.
Further, the display unit 14 may be configured to, if a change of the applications to be restricted is detected, make a notice of the change through voice or text.
