However, in the case of the receiving side, nothing is taken into account, and there is a problem that when the receiving side wants to call the calling side, the calling side and the receiving side make calls again at the same time, making it impossible to talk to each other.

  Further, in Patent Document 2, when a call is placed, if the receiving terminal is in a power-off state or out of service area, the line connection device server creates a mail and passes the incoming call history to the mail server. An invention has been disclosed in which an incoming call history is mailed when the mobile phone is turned on or out of service area so that the incoming call history can be seen on the incoming side mobile terminal. However, a response to a case where the call is disconnected halfway for some reason is not considered.

Patent Document 3 discloses an invention in which communication is interrupted and a message indicating whether to redial is displayed when communication is interrupted for a certain period of time. However, when the calling side and the receiving side make a call again at the same time, there is a problem that they are in a call state and cannot make a call.
Patent Document 4 discloses an invention in which when a call is disconnected during a call, if the call disconnection determination circuit determines that the call has not ended normally, a re-transmission operation is performed on the other party whose call has been disconnected. It is disclosed. However, when the calling side and the receiving side make a call again at the same time, there is a problem that they are in a call state and cannot make a call.

Hereinafter, a portable communication device according to an embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, an example of a mobile phone will be described as a portable communication device.
FIG. 1 is a block diagram of a portable communication device according to an embodiment of the present invention, showing an example of a cellular phone.

  In FIG. 1, a mobile phone 100 has a voice input / output unit 101 as a voice input / output unit having a speaker and a microphone, a memory 102 as a storage unit, a central processing unit (CPU) 103 as a control unit, and transmits and receives signals wirelessly. An antenna 104 and a transmission / reception unit 105 constituting a transmission / reception unit for operation, an operation unit 106 as an operation unit having a plurality of operation keys, and a display unit 107 as a display unit constituted by a liquid crystal display device (LCD). .

The transmission / reception unit 105 transmits and receives voice, electronic mail, and the like wirelessly via the antenna 104. The CPU 103 implements various functions by executing programs stored in the memory 102 and performs processing as described below.
2 and 3 are flowcharts showing processing of the mobile phone 100 shown in FIG. 1, and are mainly flowcharts showing processing of the CPU 103. FIG. FIG. 2 shows the processing of the calling-side mobile phone, and FIG. 3 shows the processing of the receiving-side phone.

  Hereinafter, the operation of the mobile phone according to the embodiment of the present invention will be described in detail. Note that the user A and the user B both have the cellular phone 100 configured as shown in FIG. 1 (hereinafter, the symbols A and B are added to represent the cellular phones of the users A and B and their components). A case will be described in which communication is performed using the mobile phone 100A of the user A who is the caller and the mobile phone 100B of the user B who is the callee.

First, processing of the mobile phone 100A of the user A will be described with reference to FIG.
Under the control of the CPU 103A, the mobile phone 100A of the user A makes a call to the mobile phone 100B of the user B who is the called party, and makes a normal call (step S101).
Thereafter, when the radio wave state of the mobile phone 100 of either the user A or B becomes unstable during a call and the line is disconnected, the CPU 103A of the mobile phone 100A detects that the communication is disconnected (step S102).

  Next, the CPU 103A of the originating mobile phone 100A recognizes that the communication has been interrupted without pressing the Hold button (included in the operation unit 106), which is an operation button for terminating communication (step S103), and the mobile phone 100A. The display unit 107A displays the telephone number of the mobile phone 100B of the other party (user B) and automatically redials the mobile phone 100B of the other party B (step S104). For example, if the CPU 103A recognizes that communication has been interrupted without pressing the Hold button, which is an operation button for ending communication included in the operation unit 106A of the mobile phone 100A to which the CPU 103A belongs, the CPU 103A calls the display unit 107A of the mobile phone 100A. The telephone number of the mobile phone 100B of the other party (user B) is displayed, and redialing is automatically performed to the mobile phone 100B of the other party B.

  CPU 103A determines whether or not call partner B has responded (step S105). When the radio wave condition becomes good and call partner B responds with mobile phone 100B, the call between mobile phones 100A and B resumes. (Step S106). In step S105, the CPU 103A does not resume the call because there is no response from the call partner B when the radio waves of the mobile phones A and B of the user A or the call partner B are bad and out of the communication range. The process ends (step S107).

On the other hand, in the mobile phone 100B on the called party B side, the CPU 103B performs the processing of FIG.
In FIG. 3, first, the CPU 103B receives an incoming call from the mobile phone 100A on the caller A side and makes a normal call (step S201).
Thereafter, when the radio wave state of one of the mobile phones A or B becomes unstable during a call and the line is disconnected, the CPU 103B of the mobile phone 100B detects that the communication is disconnected (step S202).

Next, when the CPU 103B of the receiving-side mobile phone 100B recognizes that the communication has been interrupted without pressing the Hold button, which is an operation button for ending communication included in the operation unit 106B (step S203), the mobile phone on the caller A side The mobile phone 100A waits for an incoming call by automatic redialing, which is a state for determining whether there is an incoming call from the telephone 100A (step S204). For example, if the CPU 103B determines that communication has been interrupted without pressing the Hold button, which is an operation button for ending communication included in the operation unit 106B of the mobile phone 100B to which it belongs, the mobile phone 100A on the caller A side In this state, it is determined whether or not there is an incoming call from the mobile phone 100A.
If CPU 103B determines in step S204 that there is an incoming call from mobile phone 100A within a predetermined time (for example, a few dozen seconds) after the disconnection of communication, CPU 103B resumes the call (step S205).

If CPU 103B determines in step S204 that the incoming call from mobile phone 100A on the side of caller A is not within the predetermined time since the disconnection of communication (step S206), whether or not to call back from mobile phone 100B to mobile phone 100A is determined. The display urging the operation input by the operation unit 106 is performed on the display unit 107B (step S207).
When the user B selects and inputs that the call is not re-applied (No) on the display unit 107B by the operation of the operation unit 106B, the CPU 103B determines that the call is not re-applied (step S208) and ends the process.

On the other hand, in step S208, CPU 103B dials to caller A when it determines that the operation unit 106B has selected that input is to be repeated (Yes) on display unit 107B (step S209).
Next, the CPU 103B determines whether or not the mobile phone 100A of the user A has responded (step S210), and when determining that it has responded, resumes the call (step S211). On the other hand, if the CPU 103B determines in step S210 that there is no response due to the poor radio wave condition of the mobile phone 100A on the user A side, the CPU 103B ends the process without resuming the call (step S212).

  As described above, the mobile phone 100, which is a type of portable communication device according to the embodiment of the present invention, is operated by the operation unit 106 and a reception start operation of the operation unit 106 in response to an incoming call from the communication partner. Transmission / reception means (antenna 104 and transmission / reception unit 105) for establishing communication with the communication partner and communication established after communication is established between the communication partner and the communication termination operation of the operation unit 106 are not performed. And a control means (CPU 103) for controlling the transmission / reception means to wait for a predetermined time for an incoming call from the communication partner.

Further, the control means is configured to control the transmission / reception means so as to make a call to the communication partner after the predetermined time has elapsed.
In addition, the control unit has a display unit 107, and when the communication is interrupted regardless of the communication end operation of the operation unit 106, the control unit performs a display for prompting the communication partner to make a call to the communication partner. In response to an input operation for initiating transmission by 106, the transmission / reception means is controlled to transmit to the communication partner after the predetermined time has elapsed.

In addition, the transmission / reception unit transmits a call to the communication partner in response to a transmission operation of the operation unit 106, and the control unit is configured to transmit the communication with the communication partner by the transmission / reception unit. When the communication is interrupted regardless of the communication end operation, the transmission / reception means is controlled to re-transmit to the communication partner.
When the control unit of the calling-side mobile phone 100A determines that the communication is interrupted regardless of the operation of the operation unit 106, the display unit 107A of the mobile phone 100A displays the communication partner (user B) mobile phone 100B. The telephone number is displayed and redialing is automatically performed to the mobile phone 100B of the other party B.
As described above, when a line disconnection occurs due to the deterioration of the radio wave state during a call on the mobile phone 100, the mobile phone 100A on the caller A side can automatically redial to the other party (the caller B side) and reversely receive the call. The party B waits for a predetermined time for a re-call from the caller A.

As a result, when the line is interrupted during a call between the mobile phones 100, the caller A automatically makes a call again, and the redial from the callee B is suppressed within a predetermined time. Therefore, it is possible to prevent a disconnection state caused by calling each other.
Also, in the past, the user had to press the Hold button and select the other party by redialing, and then had to make a call. However, it is possible to automatically redial when it is recognized that the call has been cut off, improving operability. It becomes possible to do.

On the other hand, in the mobile phone 100B on the called party B side, when the call is cut off during the call, if there is no incoming call from the caller A within a predetermined time, the mobile phone of the caller A that was on the call until then The user is prompted to input whether or not to make a call to 100A, and when an input to make a call is made, the call is sent to the mobile phone 100A on the caller A side.
In addition, when the control unit of the receiving-side mobile phone 100B determines that the communication is interrupted without performing the communication end operation of the operation unit 106B, the control unit determines whether there is an incoming call from the mobile phone 100A on the caller A side. In this state, the mobile phone 100A waits for an incoming call by automatic redialing for a predetermined time.
As a result, even when there is no re-call from the caller A, it is possible to prevent the occurrence of a missed call by calling each other and to easily resume the call by calling from the caller B side. The effect of becoming.

When the radio wave condition of user A's mobile phone 100A is poor and the mobile phone 100B on the other party B cannot respond (step S305), the CPU 103A displays a display prompting the user to create an e-mail. This is performed (step S307).

Next, when the user A performs an email creation process by operating the operation unit 106A, the CPU 103A performs an email creation process in response to the operation of the operation unit 106A (step S308).
Next, the CPU 103A determines whether or not the radio wave condition of the mobile phone 100A on the sending side A is good (step S309). If the radio wave condition is good, the mail is sent to the communication partner B for processing. Is finished (step S310).

  On the other hand, in step S309, if the CPU 103A determines that communication is not possible due to the poor radio wave condition of the mobile phone 100A that transmits the mail, the CPU 103A stores the e-mail in the memory 102, and then the mobile phone 100A moves. When the radio wave condition becomes good, the cellular phone 100A automatically recognizes that the radio wave condition is good and automatically transmits the mail stored in the memory 102 (steps S309 and S310).

As described above, in the mobile phone 100 according to the other embodiment, the control unit transmits an e-mail to the communication partner when the communication is interrupted regardless of the communication end operation of the operation unit 106. In this way, the transmission / reception means is controlled.
In addition, when the communication is interrupted without the operation end operation of the operation unit 106 being performed, the control unit displays on the display unit 107 a message prompting the communication partner to send an e-mail, and the operation unit 106 performs an e-mail transmission operation. The transmission / reception means is controlled so as to transmit the electronic mail to the communication partner in response to.

Therefore, if the radio wave condition is unstable, it is difficult to continue the call by redialing, but if it is an e-mail, it can be sent easily in a place where the radio wave condition is good. Even if the radio wave condition becomes worse on the person A side or the like, it is possible to notify the other party of some information such as the current or future situation by automatically sending mail to the other party even if the incoming and outgoing calls cannot be made.
That is, as long as the user A performs the mail transmission operation using the operation unit 106, the mobile phone 100 automatically recognizes the radio wave state and moves to a good place even if the radio wave state is bad. At that time, it is possible to automatically send an e-mail and to communicate the situation to the other party.

  In addition, the communication system according to the present embodiment provides a communication system that performs communication using a single mobile phone or a plurality of mobile phones according to any of the above-described embodiments. By using the mobile phone 100, it is possible to construct a communication system capable of resuming communication more reliably even when the radio wave condition is bad and communication is interrupted during communication. In addition, when communication is interrupted during communication, it is possible to construct a communication system capable of transmitting information to a communication partner using electronic mail.

Although the two embodiments have been described separately, the functions according to the two embodiments may be provided in one mobile phone 100 and used by switching the operation unit 106. .
