  Processing operations in the mobile phone 1 having the above-described configuration will be described with reference to FIGS. FIG. 5 shows a processing operation in the case where the mobile phone 1 is lost or the like, so that the mobile phone 1 is remotely locked from another communication terminal.

  As shown in FIG. 5, first, the other communication terminal makes a call to the mobile phone 1 or sends an e-mail to the mobile phone 1 so as to meet the remote lock condition (step). S1 (hereinafter sometimes abbreviated as “S1”. The same applies to other steps).

  On the other hand, in the mobile phone 1, when the incoming call unit 30 receives an incoming call or email from the other communication terminal (S10), the remote lock unit 31 determines whether the incoming call is a remote lock instruction or not. (S11). That is, the remote lock unit 31 determines whether or not the incoming call matches the conditions included in the remote lock condition list 52. If the incoming call is not a remote lock instruction (NO in S11), the remote lock processing operation is terminated and the processing shifts to a normal processing operation.

  On the other hand, when the incoming call is a remote lock instruction (YES in S11), remote lock unit 31 refers to setting information list 50 and cancels the manner mode if the current mode is the manner mode (S12). -S13). That is, the remote lock unit 31 copies the storage setting information list 51 to the setting information list 50.

  Next, the remote lock unit 31 updates the setting information list 50 shown in FIG. 4 as follows. That is, the current mode is changed to remote lock, the on / off setting of various sounds is changed to “on” (S14), the various volume settings are changed to “maximum” (S15), and the various sound types are changed. The setting is changed to the type of sound for remote lock (S16 / S17). Further, the on / off setting of the automatic incoming call is changed to “ON” (S18). At this time, the incoming time may be changed. Then, the call output destination setting is changed to the speaker (S19). Thereafter, the remote lock processing operation is terminated.

  FIG. 6 shows a call processing operation when the mobile phone 1 makes a call with another communication terminal. As shown in the figure, when the incoming call unit 30 receives a call or a videophone call (S20), the notification control unit 34 outputs a voice output control unit 35, a display control unit 36, and other outputs so as to perform incoming call notification. The control unit is instructed, and the output control unit performs incoming call notification based on the setting information list 50 (S21). At this time, in the remote lock mode, since the incoming call notification is performed at the maximum volume, it is easy for people around the mobile phone 1 to find it.

  On the other hand, the automatic receiving unit 32 determines whether or not the automatic incoming call on / off setting in the setting information list 50 is “ON” (S22). When the automatic incoming call on / off setting is “off” (NO in S 22), automatic incoming call unit 32 does not instruct caller 33. Therefore, the call unit 33 performs normal call processing. That is, the call unit 33 waits until the off-hook button of the function button group 7 is pressed or the other party (the other call terminal) stops sending (S23 / S24), and the off-hook button is pressed. (YES in S23), the process proceeds to step S29, and if the other party's transmission is stopped (YES in S24), the call processing operation is terminated.

  On the other hand, when the on / off setting of automatic incoming call is “ON” (YES in S22), automatic incoming part 32 reads the number of seconds for setting the incoming time of automatic incoming call in setting information list 50 (S25). The second counter is activated (S26) and waits until the set number of seconds elapses or the transmission of the other party (the other call terminal) stops (S27 and S28). If the set number of seconds has elapsed (YES in S27), the process proceeds to step S29, and if the other party's transmission is stopped (YES in S28), the call processing operation is terminated.

  In step S29, if the output destination setting of the call is a speaker, the audio output control unit 35 selects the speaker 41 as the output destination of the call voice (S29 / S30). Then, the calling unit 33 instructs the wireless processing unit 11 and the voice processing unit 12 to start the call, and the call is started (S31).

  At this time, since the automatic incoming call is set to “ON” in the remote lock mode (step S18 in FIG. 5), even if someone does not press the off-hook button of the lost mobile phone 1, the mobile phone 1 and You can make a call. Therefore, as described above, the user of the mobile phone 1 can easily find the mobile phone 1 while maintaining security, and can easily have another person pick up the mobile phone 1. Further, in the remote lock mode, since the output destination of the call is set to the speaker 41 instead of the receiver 40 (step S19 in FIG. 5), the range in which the call from the mobile phone 1 can be heard is widened, and others can be heard. It becomes easier to pick up the mobile phone 1 further.

  Then, when the on-hook button of the function button group 7 is pressed during the call or when the line is disconnected from the call destination, the call unit 33 terminates the call. Then, the voice processing unit 12 is instructed (S32), and the call processing operation is terminated.

  FIG. 7 shows an interrupt process when the mobile phone 1 is operated, for example, when a button of the main operation button group 6 is pressed or when the lid 3 is opened and closed. As shown in the figure, when the interrupt process is performed, the audio output control unit 35 reads the sound setting information corresponding to the corresponding operation from the setting information list 50, and outputs the sound based on the read sound setting information. The audio output unit 14 is controlled to do so. Thereby, the audio output unit 14 outputs the sound set for the corresponding operation in the setting information list 50 at the set volume (S40).

  At this time, in the remote lock mode, the sound on / off setting for various operations is set to “on” and the volume is set to “maximum” (steps S14 and S15 in FIG. 5). When another person picks up and operates the mobile phone 1, a loud operation sound is output to the surroundings. Therefore, it is possible to prevent others from trying to misuse the lost mobile phone 1.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. That is, embodiments obtained by combining technical means appropriately modified within the scope of the claims are also included in the technical scope of the present invention.
