Here, the description will focus on the parts related to the sixth embodiment.

  That is, as shown in FIG. 11, in the mobile communication device according to the sixth embodiment, in the configuration shown in FIG. 1 (first embodiment), the battery protection circuit 1101 and its invalidation circuit 1102 are a secondary battery. 109 and the power supply unit 110, an operation mode control unit 1103 is provided instead of the operation mode control unit 111, and a wireless control unit 1104 is provided instead of the wireless control unit 103. The wireless control unit 1104 is provided with a wireless control program storage unit 1105.

  The battery protection circuit 1101 is a circuit generally provided in mobile communication devices. That is, in the past, in order to avoid a decrease in life due to overdischarge of the secondary battery 109 and an unstable operation due to an increase in voltage drop due to an increase in internal resistance of the secondary battery 109, a certain amount of discharge is required. A battery protection circuit 1101 is incorporated so as to stop the operation of the mobile communication device. The operation stop is generally performed by monitoring the voltage of the secondary battery 109. In this configuration, the mobile communication device stops with a certain amount of power remaining in the secondary battery 109, and thus a problem occurs in an emergency.

  Therefore, an invalidation circuit 1102 is provided between the battery protection circuit 1101 and the power supply unit 110, and the operation mode control unit 1103 controls the invalidation circuit 1102. In other words, in the normal operation mode, the invalidation circuit 1102 connects the battery protection circuit 1101 and the power supply unit 110, and the power supply unit 110 can monitor the remaining battery level of the secondary battery 109 via the battery protection circuit 1101. I am doing so.

  Then, when the remaining battery level indicated by the remaining battery level detection signal from the power supply unit 110 reaches a predetermined value, the operation mode control unit 1103 causes the wireless control unit 1104, the application processing unit 104, and the power supply unit 110 to enter the emergency operation mode. At the same time as the switching instruction is given, an invalidation instruction signal for passing the battery protection circuit 1101 and directly connecting the secondary battery 109 and the power supply unit 110 to the invalidation circuit 1102 is issued.

  As a result, the emergency operation can be continued without worrying about the remaining battery level in the emergency operation mode caused by the remaining battery level. In order to suppress deadlock at the time of voltage drop, the wireless control unit 1104 monitors the operation in accordance with the wireless control program stored in the wireless control program storage unit 1105 and resets the power supply unit 110 when deadlock occurs. To reset the system.

  Next, the operation of the mobile communication apparatus according to the sixth embodiment configured as described above will be described along FIG. 12 with reference to FIG. FIG. 12 is a flowchart for explaining the operation of the mobile communication device shown in FIG. In FIG. 12, the same reference numerals are given to the processing procedures that are the same as or equivalent to the processing procedures illustrated in FIG. 2. Here, the description will be focused on the portion related to the sixth embodiment.

  As shown in FIG. 12, when the operation mode instructed by the operation mode control unit 1103 is not the emergency operation mode (ST210: NO), the normal operation mode 201 is executed, and when the operation mode is the emergency operation mode (ST210: YES) The operation mode 1201 is executed.

  In the emergency operation mode 1201, in the standby state (ST231), if there is no call (ST232: NO), the process returns to ST210, and the instruction content of the operation mode control unit 1103 is monitored, but if there is a call (ST232: YES) The operation mode control unit 1103 instructs the invalidation circuit 1102 to invalidate the battery protection circuit 1101 (ST1211) because the cause of the emergency operation mode to be instructed is due to the remaining battery level (ST1211). The control unit 1104 is activated (ST233). Radio control section 1104 passes a predetermined message to baseband signal processing section 102 and transmits it (ST234). Thereafter, the process returns to ST210, and the instruction content of the operation mode control unit 1103 is monitored.

  As described above, according to the sixth embodiment, when an instruction to switch to the emergency operation mode due to the remaining battery level is issued, the battery protection is canceled simultaneously with the transition to the low power operation. Therefore, in the normal operation mode, it is possible to report even when the battery is dead, and the reliability of emergency communication can be improved.

  In the sixth embodiment, the application example to the first embodiment has been described. However, the sixth embodiment can be similarly applied to the second embodiment, the third embodiment, the fourth embodiment, and the fifth embodiment. Needless to say.
