Table 2 is a list showing an example of the contention adjustment setting that can be adopted by the mobile device 20 of the present embodiment. The functions described in the left column of Table 2 are the preceding external connection communication functions that are active in the mobile device 20. The definition of “active state” is shown in Table 3. The function described in the upper column of Table 2 indicates the subsequent external connection communication function that is about to interrupt and start to use when the external connection communication function in the left column is in the active state. In addition, the functions in the left column and the upper column are described in the notation of “symbol of device name of interface device” − “symbol of external connection communication function”. Here, “BT” indicates a Bluetooth interface device that can use a multi-profile.
In Tables 2 and 3, “UART-HF” that can be used as an option is also described.

  In Table 2, “◯” indicates a setting in which when the preceding external connection communication function is in an active state, the subsequent external connection communication function is allowed to be interrupted and both can be used simultaneously. In addition, “×” indicates a setting in which, when the preceding external connection communication function is in an active state, the interruption of the subsequent external connection communication function is prohibited and only the previous external connection communication function can be used. In addition, “UI selection” outputs a display or voice guidance for prompting a function selection when there is a request for interruption of the subsequent external connection communication function, and the previous external connection communication function and the subsequent external connection communication function. A setting in which one of the users selects and uses is shown. In addition, “1” in “1: ○” indicates a case where neither voice communication nor data communication is performed in the preceding external connection communication function in the active state. Further, “2” in “2: ×” indicates a case where voice communication or data communication is being performed in the preceding external connection communication function in the active state.

  The control unit composed of the CPU 201 or the like uses other types of communication interface means when in an active state in which any one of the external connection communication devices 207A to 207E is used. When there is a use start request for requesting use of the external connection communication function, control is performed as follows. In other words, the control unit sets the preceding external connection communication function in the active state and the target of the use start request based on the contention adjustment setting data corresponding to the list of Table 2 stored in the data storage unit. The external connection interface devices 207A to 207E are controlled so as to adjust the conflict with the subsequent external connection communication function.

  FIG. 4 is a flowchart showing an example of processing in the mobile device 20 when an interruption of the subsequent external connection communication function is performed when the previous external connection communication function is active in the communication system. This example shows a case where the preceding external connection communication function in the active state is the Bluetooth communication hands-free function (BT-HF).

  First, when the Bluetooth communication hands-free function (BT-HF) is in an active state, when an interrupt is made from another external connection communication function, the type of the external connection communication function to be interrupted thereafter is set by the control unit. Judgment is made (steps S1 to S2).

  If the control unit determines that the subsequent external connection communication function to be interrupted is the modem function of “BT-modem”, “USB-modem”, or “IrDA-modem”, the subsequent modem function Are also activated, and control is performed so that both the preceding BT-HF and the succeeding modem functions can be used simultaneously (step S3).

  If the control unit determines in step S2 that the subsequent external connection communication function to be interrupted is an OBEX function of “BT-OBEX”, “USB-OBEX”, or “IrDA-OBEX”, In the preceding Bluetooth communication hands-free function (BT-HF), it is determined by the control unit whether or not telephone communication or data communication is being performed (step S4). Here, when telephone communication or data communication is being performed in the preceding BT-HF, interruption of the subsequent OBEX function is prohibited and only the preceding BT-HF can be used (step S5). On the other hand, when neither telephone communication nor data communication is performed in the preceding BT-HF, control is performed so that both the preceding BT-HF and the succeeding OBEX function can be used simultaneously (step S6).

  Further, in the step S2, the external connection communication function to be subjected to the subsequent interrupt is an external connection communication function that does not correspond to either the modem function or the OBEX function, that is, “BT-HS”, “UART-HF” or “ When the control unit determines that “10-core cable-audio / remote” is selected, control is performed to execute the next “UI selection” process. In this “UI selection” process, a display or voice guidance prompting the user to select a function is output so that the user selects either the preceding BT-HF or the succeeding external connection communication function. Then, based on the instruction content instructed by the key operation or voice input of the input device 204 by the user, only one of the preceding BT-HF and the succeeding external connection communication function is controlled to be usable (step S7). .

Even when the external connection communication function other than the Bluetooth communication hands-free function (BT-HF) is a preceding function in an active state, control is performed so as to adjust the competition according to the competition adjustment settings shown in Table 2.
For example, when the preceding function in the active state is an OBEX function of “BT-OBEX”, “USB-OBEX”, or “IrDA-OBEX”, the subsequent function of the external connection communication is not changed. Disable the external connection communication function interrupt and enable only the preceding OBEX function.

  As described above, according to the present embodiment, contention adjustment setting data for adjusting contention between a plurality of types of external connection functions that may be used at the same time is stored and set in advance in the data storage unit. Can do. And when one of multiple types of external connection communication functions is in an active state, when there is a use start request for requesting use of other types of external connection communication functions, The external connection interface devices 207A to 207E are controlled. That is, based on the contention adjustment setting data stored in advance in the data storage means, the preceding external connection communication function in the active state and the subsequent external connection communication function that is the target of the use start request (interruption target) Control to adjust for contention. Based on the contention adjustment setting data set in advance as described above, it is possible to adjust the contention between the preceding external connection communication function in the active state and the subsequent external connection communication function that is the target of the use start request (interruption target). Therefore, unlike the case where the subsequent external connection communication functions are uniformly prohibited, it is possible to more flexibly adjust the contention of a plurality of types of external connection communication functions to be used simultaneously according to the preset contents.

  Further, in the present embodiment, based on the contention adjustment setting data, the preceding external connection communication function in the active state and the subsequent external connection communication function that is the target of the use start request (interruption target) are simultaneously performed. It is determined whether or not it can be used. When both external connection communication functions can be used at the same time, both external connection communication functions are controlled to be in an active state. Therefore, the external connection communication function that is the target of the use start request (interrupt target) is uniformly set. Unlike the case of prohibition, it is possible to adjust the contention of a plurality of types of external connection communication functions so as to better meet the user's wishes.

  In the present embodiment, the preceding external connection communication function in the active state and the subsequent external connection communication function that is the target of the use start request (interruption target) are alternatively selected based on the contention adjustment setting data. It is determined whether or not it can be used. When both external connection communication functions are alternatively available, function conflict information is output to prompt the user to select either the preceding external connection communication function or the subsequent external connection communication function. The data is output by the device 205. When the user who has confirmed the function conflict information designates the external connection communication function with the input device 204, the designated external connection communication function is controlled to be activated preferentially. Accordingly, when the preceding external connection communication function and the subsequent external connection communication function are alternatively available, the external connection communication function that is the target of the use start request (interrupt target) is uniformly prohibited. In contrast, it is possible to adjust the contention of multiple types of external connection communication functions to better meet the user's wishes.

  In this embodiment, based on the contention adjustment setting data, whether the external connection communication function in the active state involves communication that cannot be interrupted, that is, data at the time of interruption of a telephone call or a series of data transfer It is determined whether or not the communication is accompanied by communication that cannot be interrupted, such as missing. If the external connection communication function in the active state involves communication that cannot be interrupted, the above-mentioned active connection communication function is rejected without activating the external connection communication function that is the target of the use start request. Control to maintain the external connection communication function of the state. By this control, it is possible to prevent the telephone call in the external connection communication function in the active state from being interrupted or the occurrence of data loss during a series of data transfer.
