2. Description of the Related Art In a conventional cellular system, if the network or the mobile telephone terminal has an unintended failure at the wireless section interface between the mobile telephone terminal and the network, and it is difficult to make a call or the communication during the call is interrupted, the movement occurs. The communication control unit of the telephone terminal tries to resume the call by performing the restoration process, but if the call cannot be restored, the communication control unit of the mobile telephone terminal shifts to the standby shift operation which is the initial state.

When the operation shifts to the standby shift operation, the user monitors the display device of the mobile telephone terminal and confirms by himself that the mobile telephone terminal has shifted to the standby state in which the mobile telephone terminal can make a call, and then performs the operation for making a call again. You must make an outgoing call request. Since mobile phone terminals are sometimes used while moving, such as running or walking, after monitoring the transition to the standby state where the user can make a call and recognizing the transition to the standby state, Requesting an operation for making a call disperses the user's attention while moving, and requests the user for unnecessary work.

[0004]

According to the standard (RCR STD-27) of the digital car telephone system, when the failure monitoring of the wireless section interface and the occurrence of the failure are recognized as the function of the communication control unit, the recovery processing or the initial state is performed. The transition to the standby shift operation is performed. Regarding the processing when a failure occurrence is detected by the failure monitoring in the wireless section interface, the operation procedure of the corresponding mobile phone terminal is specified in the standard for each content of the failure. There is no problem if you control it according to the street. However, from the viewpoint of improving the usability, unless a separate process is provided in the case of a failure in the wireless section interface, the user is caused to perform useless operations. For example, if a mobile phone terminal enters the shadow of a tunnel or building and is out of the line-of-sight range of the network side (radio base station) antenna, the wireless section interface is temporarily interrupted and the call is interrupted during a call. Sometimes it happens. In that case, in order to resume the call with the person who was in the call, the user confirmed on the display device of the mobile phone terminal that the user came out of the shadow of the tunnel or building and was within the line-of-sight range of the radio base station antenna. Above, you have to perform the operation for making a call again. If the user makes a call operation without confirming the recovery of the fault in the wireless section between the network side and the mobile telephone terminal, the call request may become invalid, and the user has to perform the call operation again. There are also drawbacks.

An object of the present invention is to monitor faults in a wireless section when the mobile telephone terminal enters a tunnel or a shadow of a building and communication is interrupted due to a temporary interruption in the wireless section. An object of the present invention is to provide a mobile telephone that automatically makes a call to the other party who is in a call after recovery from a failure and recovers the call to prevent the user from performing unnecessary operations as much as possible.

[0006]

According to the present invention, a wireless section is monitored during communication, and when an unintended failure occurs on the network side or the mobile telephone terminal side, it is indicated to the display device of the mobile telephone terminal to that effect. Is displayed, and when the recovery from the failure is recognized, the function that the mobile phone terminal starts automatic call to the other party without displaying the fact to the other party who is talking is required. Provided.

Further, according to the present invention, when the user makes a dial input and is requested to make a call before the mobile telephone terminal shifts from the standby transition operation which is the initial state to the standby state, the mobile telephone terminal is After holding the entered dialing information and outgoing call request, displaying that fact on the display device of the mobile phone terminal, suspending the execution of outgoing call processing until transitioning to standby, and after confirming the transition to standby, notify that effect. A function is provided to start the outgoing call processing that was displayed and then held.

Further, according to the present invention, by setting a standby time for waiting for a failure recovery in a wireless section or a transition to a standby state where transmission is possible for autonomous transmission, the set time range is set. Since the automatic call is permitted only in the inside, a function is provided to prevent the user from being confused by the automatic call when the user does not intend.

[0009]

According to the present invention, when a call is interrupted due to a break in radio waves due to a temporary failure in a wireless section, the mobile telephone terminal sends a call to the call partner to restart the call to the call partner. A mobile telephone that does not require the user's trouble is provided by automatically making a call immediately after the fault in the section is recovered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a control procedure when a mobile telephone terminal detects a radio wave interruption due to a failure in a wireless section during communication. When the mobile telephone terminal detects a radio wave interruption, it starts a standby timer 10a, displays the standby state on the display device by the standby state display 12a, and then shifts to the standby mode 11 of the communication control unit.
Waits for completion of state transition to standby mode 10
b, 13. If the standby shift processing 11 of the communication control unit is completed before the standby timer times out and transitions to the standby state, the standby timer is stopped 10c, the standby display is erased and the automatic transmission display 12b is displayed, and the telephone number of the other party in communication is displayed. Read setting from storage device including redial memory 1
Then, the call processing 15 is executed by an autonomous call request.

When the activation of the communication channel is completed and the calling of the communication partner is started, the automatic transmission display is erased 12c.
Also, when the standby timer times out 10b, the standby display is deleted and the automatic transmission for the current radio interruption is disabled 1
After setting to 6, the operation shifts to the normal out-of-service operation.

FIG. 2 shows an example of a control procedure when a call is issued by a user operation immediately after the power is turned on or while the out-of-service area is displayed. When the mobile telephone terminal issues a call request 20 from the user immediately after the power is turned on, immediately after the end of the call, or during the out-of-service display, the mobile phone terminal executes the call processing 15 if it is on standby. When the transition to the standby state in which the standby transition is possible and the transmission is not completed is not completed, the transmission processing cannot be performed, so the standby timer is started 10a and the transition to the standby state in which the transmission is possible by the state monitor 21 of the standby transition operation is performed. After shifting to the waiting state 13 and the waiting state, the dialing number input by the user 20 is set 14 and the outgoing call process 15 is executed by an autonomous outgoing call request.
