Description

  The present invention relates to a mobile terminal, an operation mode switching method, and a mobile communication system.

  Mobile terminals such as mobile phones include additional functions associated with mobile terminals such as wireless LAN, Bluetooth, and USB. That is, the mobile terminal includes an additional function used for purposes other than communication with the base station of the mobile communication system. When using such an additional function, it is desirable to set the additional function to ON before the start of use and to set the additional function to OFF after the use ends.

  When a personal computer and a mobile terminal are connected via a USB cable for communication, the mobile terminal user needs to set the USB mode of the mobile terminal according to the function to be used. For example, when data is transferred between a personal computer and a mobile terminal, the mobile terminal user needs to set the USB mode to the communication mode.

  For example, Patent Document 1 (Japanese Patent Laid-Open No. 2007-221502) and Patent Document 2 (Japanese Patent Laid-Open No. 2000-78656) propose a method for setting a manner mode and an incoming call notification based on area information of a mobile terminal. . However, these patent documents do not propose a specific method for setting an operation mode of an additional function attached to a mobile terminal.

JP 2007-221502 A JP 2000-78656 A

  In order to switch an additional function associated with a mobile terminal such as a wireless LAN, Bluetooth, or USB, the mobile terminal user needs to manually set on / off of the additional function or an operation mode from a menu of the mobile terminal. . Also, because of the manual setting, if the mobile terminal user forgets to turn off the additional function after the use is completed, the battery of the mobile terminal is wasted.

  Therefore, it is desirable to automatically switch the operation mode based on the location information of the mobile terminal. Furthermore, when the additional function is in use, it is desirable to switch the operation mode after use.

  The present invention has been made to solve at least one of the above-described problems, and an object thereof is to efficiently set an operation mode of an additional function associated with a mobile terminal.

  Embodiments of the present invention will be described below with reference to the drawings.

  In the embodiment of the present invention, the mobile terminal automatically switches the operation mode of the additional function unit attached to the mobile terminal based on the location information. The location information is information indicating the position of the mobile terminal, and here, a combination of a plurality of cell identifiers (cell IDs) is used.

  First, when the mobile terminal user switches the operation mode of the additional function unit, the correspondence between the switched operation mode and the location information is stored in the storage unit of the mobile terminal. When the current location information received by the mobile terminal matches the location information stored in the storage unit, the mode is automatically switched to the corresponding operation mode. However, when the additional function unit is in use, the operation mode may be switched after the use is completed.

  FIG. 1 shows a conceptual diagram (part 1) of operation mode switching in a mobile communication system according to an embodiment of the present invention. A mobile communication system includes a base station and a mobile terminal. The service area of each base station is called a cell. The cell may be divided into a plurality of sectors. The base station transmits a cell identifier (cell ID) for identifying a cell or a sector for each cell or for each sector. The mobile terminal can use a cell identifier (cell ID) as location information. For example, 512 types of codes (Primary Scrambling Code) may be used as the cell identifier. In the embodiment of the present invention, since a combination of a plurality of cell identifiers is used as the location information, the possibility of erroneous determination can be reduced even if 512 types of codes are repeatedly used in different cells.

  The mobile terminal has an additional function unit attached to the mobile terminal, such as a wireless LAN function unit, a Bluetooth function unit, or a USB function unit. Here, the additional function unit is a function used for purposes other than communication with the base station. For example, the additional function unit may communicate by setting a communication path with a communication partner other than the base station. For example, a wireless LAN function unit can communicate with a wireless LAN access point by setting a communication channel, a Bluetooth function unit can communicate with a communication partner having a Bluetooth function by setting a communication channel, and a USB function unit You can set up a communication channel and communicate with devices such as personal computers connected to the. Further, the additional function unit may operate without communication. For example, the music player function unit can reproduce music stored in the memory, and the radio function unit can reproduce radio broadcasts by receiving radio waves.

  Since these additional function units are used for purposes other than communication with the base station of the mobile communication system, it is desirable that they be set to ON before the start of use and OFF after the end of use. For example, when a mobile terminal user sets and uses a wireless LAN function unit of a mobile terminal in a registration area such as in a house, the wireless LAN function unit is automatically turned on in the house. It is desirable that the wireless LAN function unit be automatically turned off. For this reason, when the mobile terminal user turns on the wireless LAN function unit of the mobile terminal in the house, this operation mode is stored in association with the location information. For example, the ON operation mode of the wireless LAN function unit is stored in association with the cell ID of the base station A, the cell ID of the base station B, and the cell ID of the base station C. Next, when the mobile terminal user enters the house with the mobile terminal, the combination of the received plurality of cell IDs matches the location information stored in the storage unit, so the wireless LAN function unit is automatically turned on. Can be switched to.

  FIG. 2 shows a conceptual diagram (part 2) of operation mode switching in the mobile communication system according to the embodiment of the present invention. For example, a mobile terminal user sets and uses the USB function unit of the mobile terminal in a microSD mode in a registration area such as in a house, and sets the USB function unit in a communication mode (modem communication) outside the registration area. When used, it is desirable that the USB function unit automatically enters the microSD mode inside the house and the USB function unit automatically enters the communication mode outside the house. However, if the user enters the house while using the communication mode of the USB function unit outside the house and the USB function unit automatically enters the microSD mode, the communication is cut off halfway. It is inconvenient for communication to be disconnected in this way. For this reason, when the communication mode of the USB function unit is used, the microSD mode may be set after the communication mode ends. Specifically, the communication mode may be maintained until the USB cable connected to the USB function unit is removed, and the microSD mode may be set after the USB cable is removed.

<Block diagram of mobile terminal>
FIG. 3 shows a block diagram of the mobile terminal 10 according to the embodiment of the present invention. The mobile terminal 10 is a device that can communicate with a base station. The mobile terminal 10 can be used for purposes other than communication with the base station, and has an additional function unit having a plurality of operation modes. For example, the additional function unit may perform communication by setting a communication path with a communication partner other than the base station, or may operate without communication. The mobile terminal 10 includes a wireless communication unit 101, a storage unit 103, a control unit 105, a display unit 107, an operation unit 109, and an operation mode setting unit 111. For example, the mobile terminal 10 includes a wireless LAN function unit 113a, a Bluetooth function unit 113b, and a USB function unit 113c as additional function units.

  The wireless communication unit 101 receives a plurality of cell IDs from the base station. The plurality of received cell IDs are notified to the control unit 105 as a current cell ID list.

  The storage unit 103 may store a plurality of cell IDs (current cell ID list) received by the wireless communication unit 103. In addition, the storage unit 103 has an operation mode setting table that stores the correspondence between the operation mode and the location information for each additional function unit. For example, the operation mode setting table for the Bluetooth function unit 113b stores a cell ID list when Bluetooth is set on and a cell ID list when Bluetooth is set off. For example, the operation mode setting table for the USB function unit 113c includes a cell ID list when the USB is set to the communication mode, a cell ID list when the USB is set to the microSD mode, and the USB is MTP (Media The cell ID list when the mode is set to the transfer protocol mode is stored. The priority of each operation mode may be further stored in the operation mode setting table. For example, the priority is used when a plurality of operation modes correspond to switching targets.

  The storage unit 103 may have a state storage table that stores the valid / invalid state of the cell ID automatic registration function and the valid / invalid state of the automatic mode switching function. When the cell ID automatic registration function is valid, the location information in the operation mode setting table is updated when the operation mode is switched. A specific update procedure will be described later. For example, in a place where a mobile terminal user does not go on a daily basis, it is possible to prevent unnecessary cell IDs from being registered in the location information of the operation mode setting table by disabling the cell ID automatic registration function. When the automatic mode switching function is valid, the operation mode is automatically switched when the operation mode switching condition is met. For example, in a place where a mobile terminal user does not go on a daily basis, it is possible to prevent an unintended operation mode switching due to an erroneous determination of a cell ID by disabling the automatic mode switching function.

  The control unit 105 compares the received plurality of cell IDs (or the current cell ID list of the storage unit 103) with the cell ID list stored in the operation mode setting table of the storage unit 103, and operates the additional function unit Determine whether to switch modes. For example, the received plurality of cell IDs (or the current cell ID list of the storage unit 103) is compared with the cell ID list stored in the operation mode setting table of the storage unit 103, and a predetermined number or more of cell IDs (for example, If three or more cell IDs) match, the corresponding operation mode is selected. When a plurality of operation modes are selected according to the conditions, the control unit 105 may select an operation mode with a higher priority. The selected operation mode is notified to the operation mode setting unit 111.

  The operation mode setting unit 111 switches the operation mode of each additional function unit according to the operation mode selected by the control unit 105. However, when the additional function unit is in use, the operation mode is switched after the use is completed. Note that the end of use refers to a state in which the operation of the additional function is turned off or stopped. For example, when the additional function sets up a communication path with a communication partner other than the base station and communicates, the end of use refers to a state in which the communication path set in the additional function unit is disconnected. For example, the end of use of the wireless LAN function unit 113a may be when the wireless LAN access point is outside the communication range, and the end of use of the Bluetooth function unit 113b may be when the power of the communication partner is turned off. The end of use of the USB function unit 113c may be when the USB cable connected to the USB function unit 113 is removed.

  The display unit 107 displays a valid / invalid state of the cell ID automatic registration function and the automatic mode switching function. The display unit 107 displays the priority of each operation mode stored in the operation mode setting table.

  The operation unit 109 receives a valid / invalid state of the cell ID automatic registration function and the automatic mode switching function from the mobile terminal user. The operation unit 109 receives the priority of each operation mode from the mobile terminal user. Information input from the mobile terminal user is stored in the storage unit 103. Note that the cell ID automatic registration function, automatic mode switching function, and priority do not necessarily have to be input via the operation unit 109, and initial values are set at the time of shipment of the mobile terminal in order to reduce the user's trouble. May be.

<Flowchart of operation mode switching method>
FIG. 4 shows a flowchart of the operation mode switching method according to the embodiment of the present invention. First, in the operation mode registration process (S11), the correspondence between the operation mode of the additional function unit and the location information is registered. Initially, the mobile terminal user manually switches the operation mode. At this time, the correspondence between the operation mode and the location information is registered. Next, in the switching determination process (S12), the mobile terminal receives the cell ID, and when there is a change in the received cell ID, performs switching determination of each additional function unit. In the switching determination of each additional function unit, it is determined whether or not to switch the operation mode of the additional function unit based on a comparison between the received plurality of cell IDs and the cell ID list stored in the storage unit. Next, in the operation mode switching process (S13), the operation mode of the additional function unit is switched. However, when the additional function unit is in use, the operation mode may be switched after the use is completed. When the operation mode is switched, the operation mode registration process (S11) may be returned, and the location information corresponding to the switched operation mode may be updated. Thereafter, the change of the received cell ID is monitored in the switching determination process (S12).

  A detailed procedure of each of these processes will be described with reference to FIGS. Here, although the procedure of each process is demonstrated using the component of the mobile terminal 10 of FIG. 3, these procedures may be performed by another component.

  FIG. 5 shows a detailed flowchart of the operation mode registration process. First, it is determined whether the cell ID automatic registration function stored in the storage unit 103 is in a valid state or an invalid state (S111). In the invalid state, the correspondence between the operation mode and the location information is not registered in the storage unit 103, and the process ends. When the cell ID automatic registration function is in the valid state, the control unit 105 stores the correspondence relationship between the operation mode and the location information in the storage unit 103 (S113). Specifically, when the operation mode is switched in each additional function unit, the control unit 105 switches the plurality of cell IDs received by the wireless communication unit 101 (or the current cell ID list in the storage unit 103). The data is stored in the operation mode setting table of the storage unit 103 in association with the operation mode. Initially, since the location information is not stored in the operation mode setting table, the mobile terminal user needs to manually switch the operation mode. At this time, the cell ID (current cell ID list) is stored in the operation mode setting table in association with the operation mode. For example, as shown in FIG. 8B, when the mobile terminal user sets the operation mode of the Bluetooth function unit 113b to OFF, the cell ID (5, 24, 59, 205) at the time of setting corresponds to the OFF mode. In addition, it is stored in the operation mode setting table for the Bluetooth function unit 113b. When the mobile terminal user sets the operation mode of the Bluetooth function unit 113b to ON, the cell ID (12, 77, 136) at the time of setting is associated with the ON mode, and the operation mode for the Bluetooth function unit 113b is set. Stored in the configuration table. Further, as shown in FIG. 9B, when the mobile terminal user sets the operation mode of the USB function unit 113c to the communication mode, the cell ID (12, 77) at the time of setting is associated with the communication mode. And stored in the operation mode setting table for the USB function unit 113c. When the mobile terminal user sets the operation mode of the USB function unit 113c to the microSD mode, the cell ID (77, 136) at the time of setting is associated with the microSD mode, and the operation mode setting for the USB function unit 113c is performed. Stored in a table. When the mobile terminal user sets the operation mode of the USB function unit 113c to the MTP mode, the cell ID (5, 14, 34) at the time of setting is associated with the MTP mode, and the operation for the USB function unit 113c is performed. Stored in the mode setting table. Note that the cell ID received by the wireless communication unit 101 may not be stored in the operation mode setting table during the period in which the operation mode set by the additional function unit is used. The cell ID (current cell ID list) received by the wireless communication unit 101 is stored when the operation mode of the additional function unit is switched. Thereby, the length of the cell ID list stored in the operation mode setting table can be reduced.

  FIG. 6 shows a detailed flowchart of the switching determination process. First, when at least one cell ID among a plurality of cell IDs received by the wireless communication unit 101 changes (S131), whether the automatic mode switching function stored in the storage unit 103 is in an enabled state or in an disabled state. It is determined (S131). In the invalid state, the operation mode of each additional function unit is not switched, and the process ends. When the automatic mode switching function is valid, the switching determination process of each additional function unit is executed.

  In the switching determination process of each additional function unit, the control unit 105 includes the received plurality of cell IDs (or the current cell ID list of the storage unit 103) and the cell ID list stored in the operation mode setting table of the storage unit 103. Are compared (S141). For example, in the operation mode setting table in which three or more cell IDs are stored, it is determined whether or not the received plurality of cell IDs match three or more cell IDs (S142). If three or more cell IDs do not match, it is determined whether or not the plurality of received cell IDs match the two cell IDs in the operation mode setting table in which the two cell IDs are stored ( S143). Further, if the two cell IDs do not match, it is determined whether or not the plurality of received cell IDs match one cell ID in the operation mode setting table in which one cell ID is stored ( S144). If the cell IDs do not match, the process ends. That is, the operation mode of the additional function unit cannot be switched. When three or more cell IDs match in S142, two cell IDs match in S143, or one cell ID matches in S144, the control unit 105 determines whether there is one matched list. It is determined whether or not (S145). In the case of matching with a plurality of lists, that is, when a plurality of operation modes correspond to switching targets, the control unit 105 considers the priority and selects the operation mode with the higher priority (S147). For example, as shown in FIG. 8A, when the received plurality of cell IDs (current cell ID list) are (12, 45, 77, 136), the operation mode setting table for the Bluetooth function unit 113b Among them, there is an on mode (12, 77, 136) in which three cell IDs (12, 77, 136) match. Therefore, the control unit 105 selects the ON operation mode. Further, as shown in FIG. 9A, when the received plurality of cell IDs are (12, 45, 77, 136), three or more cells in the operation mode setting table for the USB function unit. There is no operation mode in which the IDs match, but there are a communication mode (12, 77) and a microSD mode (77, 136) in which the two cell IDs match. Among these operation modes, the control unit 105 selects a communication mode with a higher priority. Such additional function section switching determination processing is repeated for each additional function section.

  In the flowchart of FIG. 6, in the comparison of cell IDs, it is determined in order that three or more cell IDs, two cell IDs, and one cell ID match, but other determination conditions may be used. Good. For example, a match between four or more cell IDs, three cell IDs, two cell IDs, and one cell ID may be sequentially determined. As another example, a match between two or more cell IDs and one cell ID may be sequentially determined.

  FIG. 7 shows a detailed flowchart of the operation mode switching process. First, when the operation mode setting unit 111 receives the operation mode selected by the control unit 105, the operation mode setting unit 111 determines whether or not the additional function unit is in use in the current operation mode (S151). If it is in use, it waits until the end of use (S153). After the use is completed, the operation mode setting unit 111 switches to the operation mode selected by the control unit 105 (S155).

  An operation mode registration process is further executed after the operation mode switching process. Even when the operation mode is automatically switched according to the operation mode switching determination process and the operation mode switching process, it is preferable to update the location information in the operation mode setting table in order to improve the switching determination. As described with reference to FIG. 5, it is determined whether the cell ID automatic registration function stored in the storage unit 103 is in a valid state or an invalid state (S111). In the invalid state, the location information is not updated in the storage unit 103, and the process ends. When the cell ID automatic registration function is in the valid state, the control unit 105 updates the correspondence relationship between the operation mode and the location information in the storage unit 103 (S113). Specifically, when there is a cell ID that is not stored in the operation mode setting table as the location information among the plurality of received cell IDs, the control unit 105 displays the cell ID list of the operation mode setting table. Update. For example, as shown in FIG. 8A, the received cell IDs (current cell ID list) are (12, 45, 77, 136), and the Bluetooth function unit 113b is automatically set to ON. In this case, as shown in FIG. 8C, the cell ID (45) that is not stored in the operation mode setting table corresponding to the on mode is added as the on-mode location information. Further, as shown in FIG. 9A, the received plurality of cell IDs (current cell ID list) are (12, 45, 77, 136), and the USB function unit 113c automatically sets the communication mode. If the cell ID is set, the cell ID (45, 136) not stored in the operation mode setting table corresponding to the communication mode is added as the location information of the communication mode.

<Flowchart of Modification of Switching Determination Process of Each Additional Function Unit>
FIG. 10 shows a flowchart of a modification of the switching determination process of each additional function unit. In this modification, an operation mode in which, for example, less than three cell IDs are stored in the operation mode setting table is not subjected to the switching determination process.

  Specifically, the control unit 105 compares the received plurality of cell IDs (or the current cell ID list of the storage unit 103) with the cell ID list stored in the operation mode setting table of the storage unit 103 (S241). ). For example, in the operation mode setting table in which three or more cell IDs are stored, it is determined whether or not a plurality of received cell IDs match three or more cell IDs (S242). If three or more cell IDs do not match, the process ends. That is, the operation mode of the additional function unit cannot be switched. When three or more cell IDs match in S242, the control unit 105 determines whether or not there is one matching list (S245). In the case of matching with a plurality of lists, that is, when a plurality of operation modes correspond to switching targets, the control unit 105 considers the priority and selects the operation mode with the higher priority (S247). For example, as shown in FIG. 9B, among the cell IDs stored in the operation mode setting table for the USB function unit 113c, the determination of the communication mode in which two cell IDs are stored and the microSD mode is performed. Not executed. According to this modification, unintended operation mode switching due to erroneous determination of the cell ID can be prevented.

  In the flowchart of FIG. 10, as a condition that is not a target of the switching determination process, a case where there are less than three cell IDs stored in the operation mode setting table is shown, but different cell IDs may be used. . For example, when the number of cell IDs stored in the operation mode setting table is less than four, it may not be set as a switching determination target. As another example, when the number of cell IDs stored in the operation mode setting table is less than two, it may not be set as a switching determination target.

<Flowchart of Modification Using Usage Time>
With reference to FIG. 11 to FIG. 13, a modified example using the usage time as the priority will be described. As described above, when a plurality of operation modes correspond to switching targets, the operation mode with the higher priority is selected. When the usage time is used as the priority, the operation mode with the longer usage time is selected when a plurality of operation modes correspond to switching targets.

  FIG. 11 shows an operation mode setting table when the usage time is used as the priority. The operation mode setting table may store the total use time using each operation mode as a priority.

  FIG. 12 shows a flowchart of the operation mode registration process when the usage time is used as the priority. First, it is determined whether the cell ID automatic registration function stored in the storage unit 103 is in a valid state or an invalid state (S311). In the invalid state, the correspondence between the operation mode and the location information is not registered in the storage unit 103, and the process ends. When the cell ID automatic registration function is in the valid state, the control unit 105 stores the correspondence relationship between the operation mode and the location information in the storage unit 103 (S313). Specifically, when the operation mode is switched manually or automatically, the control unit 105 switches the plurality of cell IDs received by the wireless communication unit 101 (or the current cell ID list in the storage unit 103). The information is stored in the operation mode setting table of the storage unit 103 in association with the operation mode. Furthermore, the control unit 105 adds the usage time to the corresponding operation mode in the operation mode setting table (S315).

  FIG. 13 shows a flowchart of the switching determination process of each additional function unit when the usage time is used as the priority. S341 to S345 are the same processes as S141 to S145 in FIG. When it corresponds to a plurality of lists, that is, when a plurality of operation modes correspond to switching targets, the control unit 105 considers the usage time (S346). For example, the control unit 105 compares the usage times, and if these usage times are the same, the operation mode is not uniquely specified, and thus the process is terminated. If the usage times are different, the control unit 105 selects the operation mode with the longer usage time (S347).

  In the flowchart shown in FIG. 13, similarly to the modification described with reference to FIG. 10, when the number of cell IDs stored in the operation mode setting table is less than 3, for example, the operation mode does not have to be switched. Good.

  As described above, according to the embodiment of the present invention, it is possible to reduce the trouble for the mobile terminal user to set the operation mode of each additional function unit.

  In addition, since the control unit 105 determines switching of the operation mode based on a combination of a plurality of cell IDs, the possibility of erroneous determination of switching is reduced. For this reason, an additional function part is not set to ON in the place which a mobile terminal user does not intend, and possibility that a battery will be consumed wastefully will be reduced. Furthermore, when the primary scrambling code is used as the cell ID, the mobile terminal can determine the location information from the received signal. For example, in GPS positioning and base station positioning, communication with the network is required, but when using the primary scrambling code, the location information can be determined by the mobile terminal alone and communication with the network is not required. .

  Furthermore, according to the embodiment of the present invention, when the additional function unit to be switched is in use, the operation mode setting unit 111 switches the operation mode after the use is completed. For this reason, interruption of the operating mode in use is avoided.

  The storage unit 103 can set a cell ID automatic registration function and an automatic mode switching function. For this reason, in a place where the mobile terminal user does not go on a daily basis, it is possible to prevent unintended operation mode switching due to erroneous determination of the cell ID by disabling these functions.

  Furthermore, when the usage time is used as the priority, it is possible to reduce the effort for the mobile terminal user to set the priority.
