  Hereinafter, preferred embodiments of a mobile communication terminal and an operation mode switching method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic configuration diagram of a mobile communication terminal 1 according to a preferred embodiment of the present invention. As shown in FIG. 1, a mobile communication terminal 1 according to this embodiment is a communication terminal such as a mobile phone having a voice communication function and a data communication function, a PDA (Personal Digital Assistants), or a portable personal computer. It is possible to perform voice communication and data communication with the mobile communication network NW by connecting to the station 2 by a mobile communication system such as IMT-2000 (International Mobile Telecommunication 2000). Yes. In addition, the mobile communication terminal 1 can perform data communication with the external devices 3A and 3B by short-range wireless communication such as Bluetooth communication, infrared communication, and non-contact IC card communication. Here, for the sake of convenience, one base station 2 and two external devices 3A and 3B are shown in the figure, but it goes without saying that a plurality of more than that may exist.

  The mobile communication terminal 1 includes, as functional components, a position information acquisition unit (position information acquisition unit) 11, a time information acquisition unit (time information acquisition unit) 12, and a short-distance wireless unit (short-distance wireless unit). 13, a device information storage unit 14, a switching control unit (switching control unit) 15 including a mode switching processing unit 16 and a mode change detection unit 17, and a switching history information storage unit (history information storage unit) 18. Yes. Hereinafter, each component of the mobile communication terminal 1 will be described in detail.

  The position information acquisition unit 11 acquires position information indicating the current position of the mobile communication terminal 1 by executing GPS (Global Positioning System) positioning. For example, the position information acquisition unit 11 acquires position information “(45,135)” including latitude information and longitude information corresponding to the current position of the mobile communication terminal 1. In addition to acquiring position information by GPS positioning, the position information acquisition unit 11 can also be used to connect the mobile communication terminal 1 from a server device (not shown) connected to the base station 2 or the mobile communication network NW. Position information such as base station specifying information for specifying the communication area being used may be acquired. However, GPS positioning is more preferable from the viewpoint of accuracy of position information.

  The time information acquisition unit 12 acquires the current time by incorporating a clock function or the like. For example, the time information acquisition unit 12 acquires time information “Mon 19:35” specifying the day of the week and the time corresponding to the current time.

  The short-range wireless unit 13 is connected to external devices 3A and 3B that are devices close to the mobile communication terminal 1 using short-range wireless communication such as Bluetooth communication, and the short-range wireless units 31A and 3B of the external devices 3A and 3B are connected. Data is transmitted to and received from 31B. The short-range wireless unit 13 has a function of detecting the external devices 3A and 3B when establishing a connection with the external devices 3A and 3B, and when detecting the external devices 3A and 3B, the external devices 3A and 3B. Is acquired and stored in the device information storage unit 14. For example, the short-range wireless unit 13 acquires device information “device A” and “device B” for specifying the external devices 3A and 3B, adds the detection times thereof, and stores them in the device information storage unit 14.

  When the mode change detection unit 17 of the switching control unit 15 is notified of the switching of the operation mode from the mode switching processing unit 16 (details will be described later), at the same time, from the position information acquisition unit 11 and the time information acquisition unit 12. While receiving position information and time information, the device information acquired at the latest time from the device information storage unit 14 is read. Then, the mode change detection unit 17 adds the position information, time information, and device information to the switching history information regarding the switching of the operation mode by the mode switching processing unit 16 and stores it in the switching history information storage unit 18. FIG. 2 shows an example of the data structure of the switching history information stored in the switching history information storage unit 18. As shown in the figure, the operation mode change information “Manner mode ON” indicating the switching history of the operation mode is the time information “Wed 15:00” indicating the day of the week and the time zone corresponding to the switching time, and the mobile communication at the time of switching Position information “(45,135)” indicating the latitude and longitude corresponding to the position of the terminal 1, device information “none” indicating the device close to the mobile communication terminal 1 at the time of switching, and priority information “10” for switching the operation mode Are stored in association with each other. This priority information is obtained when the switching history information common to the switching history information already stored in the switching history information storage unit 18 is regenerated by the mode change detection unit 17 and the priority of the switching history information is Updated to be added.

  Returning to FIG. 1, the mode switching processing unit 16 of the switching control unit 15 determines that the mobile communication terminal 1 receives the operation mode switching request from the user of the mobile communication terminal 1 by detecting a button operation or the like. The switching of the operation mode of 1 is controlled. Then, the mode switching processing unit 16 notifies the mode change detection unit 17 that the operation mode has been switched. This "operation mode" includes a manner mode that activates the vibrator function by restricting the ringtone, a mode that restricts or stops the activation of a specific application program or communication function, and a power saving function that reduces the power consumption of a specific function. Examples thereof include a power mode and a mode for restricting access to a specific data storage area. For example, when a switching request to the “manner mode” is received from the user, the mode switching processing unit 16 performs switching to the “manner mode” and simultaneously notifies the mode change detection unit 17 of the switching.

  In addition to the operation mode switching function according to the switching request from the user as described above, the mode switching processing unit 16 also has an automatic operation mode switching function according to the switching history information read from the switching history information storage unit 18. Also have. That is, the mode switching processing unit 16 receives the latest position information and time information from the position information acquisition unit 11 and the time information acquisition unit 12 periodically or as needed, and at the same time, receives the latest proximity device information from the device information storage unit 14. Is read. Further, the mode switching processing unit 16 determines whether switching history information including information corresponding to the received position information, time information, and device information is stored in the switching history information storage unit 18. This determination is based on whether the switching history information indicates a position within a predetermined range from the current position, whether the switching history information indicates the same day and time zone as the current time, or a device in which the current proximity device is included in the switching history information This is done according to whether it matches the information. Based on the determination, the mode switching processing unit 16 specifies switching history information corresponding to the position information, time information, and device information, and controls to switch the operation mode according to the switching history information. For example, according to the example of FIG. 2, the current time is included in the time zone “Wed 15:00” indicated by the time information, and the current position is within a predetermined range from the position indicated by the position information “(45,135)”. When the proximity device is “None”, the operation mode “Manner mode” is controlled to be set to “ON”. Further, when there are a plurality of corresponding switching history information of the position information, time information, and device information, the mode switching processing unit 16 selects the operation mode according to the switching history information having the highest priority included in the switching history information. Switch. Note that the mode switching processing unit 16 may switch the operation mode with reference to only switching history information whose priority included in the switching history information is equal to or higher than a predetermined threshold. This threshold value may be different for each type of operation mode.

  Further, the mode switching processing unit 16 has a function of updating priority information of switching history information stored in the switching history information storage unit 18. Specifically, after the mode switching processing unit 16 executes the automatic switching of the operation mode based on the switching history information, when the duration of the operation mode exceeds a predetermined time, the priority is increased by “1”. On the other hand, when the duration of the operation mode is less than the predetermined time, the priority is updated to be lowered by “1”. The detection of such duration time is performed after the automatic switching to the operation mode “Manner mode” is executed and the user receives a request for switching to another operation mode or a request for canceling the operation mode “Manner mode”. This is done by measuring the time. Furthermore, in addition to the above conditions, the mode switching processing unit 16 determines the position of the mobile communication terminal 1 based on the position information acquired by the position information acquisition unit 11 and the device information stored in the device information storage unit 14. The priority information may be updated by further determining whether the position is within a predetermined range from the position at the time of automatic switching.

  Next, the operation of the mobile communication terminal 1 will be described with reference to FIG. 3 and FIG. 4, and the operation mode switching method in the mobile communication terminal 1 will be described in detail. FIG. 3 is a flowchart showing the operation when the mobile communication terminal 1 stores the switching history information, and FIG. 4 is a flowchart showing the operation during the automatic switching process by the mobile communication terminal 1.

  First, referring to FIG. 3, the operation mode is activated in a call waiting state in response to reception of an activation instruction for mobile communication terminal 1 from the user (step S101). Thereafter, a request for switching to the operation mode “manner mode” is accepted from the user (step S102). Then, the operation mode is switched to the “manner mode” by the mode switching processing unit 16, and the switching to the operation mode “manner mode” is detected by the mode change detection unit 17 (step S 103).

  At the same time as the switching of the operation mode is detected, the mode change detection unit 17 acquires time information related to the current time, position information related to the current position, and device information related to the proximity device (steps S104, S105, and S106). Next, the mode change detection unit 17 adds the time information, the position information, and the device information to the switching history information indicating the mode switching history and stores it in the switching history information storage unit 18 (step S107). At this time, the mode change detection unit 17 determines whether or not switching history information with common information is already stored (step S108). If common switching history information is stored as a result of the determination (step S108; YES), the priority information corresponding to the corresponding switching history information is updated to be increased (step S109), and the process proceeds to step S101. return. On the other hand, if the common switching history information is not stored (step S108; NO), the priority information is not updated and stored in the switching history information storage unit 18 as new switching history information, and the process returns to step S101. .

  Referring to FIG. 4, when an activation instruction for the automatic switching mode is received from the user, the operation mode is activated in a call waiting state (step S201). Thereafter, the mode switching processing unit 16 detects time information related to the current time, position information related to the current position, and device information related to the proximity device regularly or at any time (step S202).

  Then, the switching history information storage unit 18 is referred to by the mode switching processing unit 16 to determine whether there is switching history information corresponding to the time information (step S203). As a result of the determination, if there is no switching history information corresponding to the time information (step S203; NO), the process returns to step S201.

  On the other hand, when there is switching history information corresponding to the time information (step S203; YES), the mode switching processing unit 16 determines whether the device information of the switching history information corresponds to the current device information. Further determination is made (step S204). As a result, when it is determined that the device information does not correspond (step S204; NO), the process returns to step S201.

  On the other hand, if there is switching history information corresponding to the device information (step S204; YES), whether or not the position information of the switching history information corresponds to the current position information by the mode switching processing unit 16. Is further determined (step S205). As a result, when it is determined that the position information does not correspond (step S205; NO), the process returns to step S201.

  On the other hand, if there is switching history information corresponding to the position information (step S205; YES), the mode switching processing unit 16 switches the operation mode based on the switching history information with the highest priority (step S206). . Thereafter, whether or not the mode switching processing unit 16 detects re-switching to another operation mode by the user within a predetermined range from the position at the time of switching after the automatic switching of the operation mode until a predetermined time elapses. Is determined (step S207).

  As a result, when re-switching is detected (step S207; YES), the priority of the switching history information referred to at the time of automatic switching is lowered, and when the priority reaches the lower limit value, switching is performed. The history information itself is deleted (step S208). On the other hand, when re-switching is not detected (step S207; NO), the priority of the switching history information referred to at the time of automatic switching is increased (step S209). Thereafter, the process returns to step S201.

  According to the mobile communication terminal 1 and the operation mode switching method described above, the switching history information includes the time information, the position information, and the device information related to the adjacent device when receiving the operation mode switching request from the user. When the device information stored and detected by the current time, the current position, and the short-range wireless communication corresponds to the switching history information, the operation mode is switched according to the switching history information. As a result, the operation mode can be switched by comparing the time, position, and proximity device detection history at the time of operation mode switching with the current detection status, and it is optimal for the terminal usage environment that changes over time. Switch to operating mode. In particular, when the proximity device is fixed by using the detection result of the proximity device, the terminal usage environment can be determined with high accuracy, and the terminal usage environment can be determined by combining the position information by GPS positioning and the device information. This makes it possible to widen the range for determining the optimal operation mode in a spatially wide range.

  In addition, when the duration after the automatic switching of the operation mode according to the switching history information exceeds a predetermined time, the priority corresponding to the operation mode is raised, so the operation mode automatically according to the user's necessity Switching can be realized. In addition, by switching the operation mode with reference to the switching history information having a priority equal to or higher than a predetermined threshold, it is possible to prevent a situation in which the operation mode is not automatically switched to an operation mode with a low change frequency.

  In addition, this invention is not limited to embodiment mentioned above. For example, the mode switching processing unit 16 performs mode switching when the current time, current position, and device information detected by short-range wireless communication correspond to switching history information. It may be. However, it is desirable to prioritize time information and proximity device information as switching conditions. By preferentially determining these two conditions, it is possible to determine the time and the relative distance from the connection partner, that is, a certain point, so that more optimal operation mode switching is realized.

  In addition, when storing a plurality of switching history information having some common information in the switching history information storage unit 18, the mode change detection unit 17 extracts information common to the switching history information and adds new information. The switching history information may be stored in the switching history information storage unit 18. For example, the mode change detection unit 17 performs switching history information including operation mode change information “Manner mode ON”, time information “T1”, and position information “Point A”, operation mode change information “Manner mode ON”, time Switch history information including information “T2” and position information “point A”, operation mode change information “manner mode ON”, time information “T3”, and switch history information including position information “point A” are stored. In this case, the switching history information including the operation mode change information “Manner mode ON” and the position information “Point A” is newly generated and stored. Thereby, selection of the mode according to a user's necessity is made still easier.
