DESCRIPTION OF THE PREFERRED EMBODIMENTS A radio communication terminal according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a configuration block diagram of a wireless communication terminal device according to the present embodiment. In FIG. 1, an antenna unit 101 receives a signal wirelessly transmitted from a network side, and outputs the received wireless signal to a wireless unit 102. Also, the antenna unit 10
1 wirelessly transmits the signal to be transmitted to the other party received from the wireless unit 102 to the network side.

[0010] Radio section 102 frequency-converts and demodulates a radio signal received from antenna section 101, and outputs the demodulated received data to information analysis section 103. Also, the wireless unit 1
02 modulates the transmission data signal received from the information analysis unit 103 and outputs a radio signal obtained by frequency-converting the modulation to the antenna unit 101.

The information analyzing unit 103 analyzes the received data received from the wireless unit 102 and, when the received data is a control code, notifies the CPU 104, the transmission control unit 105, and the operation system control unit 107 of the control code reception. When the received data is a message, it outputs it to the CPU 104. When a time-up signal is received from the CPU 104 after notifying the CPU 104 of the reception of the control code, the CPU 104 sends an instruction to cancel the prohibition operation to the transmission control unit 105 and the operation system control unit 107.

The information analysis unit 103 includes a CPU 104
The transmission message transmitted from the communication unit 102 is output to the radio unit 102, and a control code is created according to the instruction of the CPU 104 and output to the radio unit 102.

[0013] When the transmission control unit 105 receives the control code reception notification from the information analysis unit 103, the transmission unit 105
Is forcibly controlled to be in a transmission disabled state, and thereafter, upon receiving a release command from the information analysis unit 103, the transmission disabled state is released to enable transmission from the device.

Upon receiving the control code reception notification from the information analysis unit 103, the counter unit 106 forcibly disables key input operations on the man-machine interface unit 112, and thereafter receives a cancellation command from the information analysis unit 103. And release the prohibition to enable the message input operation.

The CPU 104 executes a program stored in the memory unit 111 to realize various functions of the apparatus. In the present embodiment, the following control operations can be mainly performed. .

The CPU 104 starts the counter unit 106 upon receiving the control code reception notification from the information analysis unit 103, and outputs a time-up signal to the information analysis unit 103 when the time is up. The CPU 104 stores the received message received from the information analysis unit 103 in the text communication work area 108 and displays it on the display unit 110.

When a key input operation is performed by the man-machine interface unit 112 during message transmission, the counter unit 106
And instructs the information analysis unit 103 to create a control code. Also in this case, when the time is up, the CPU 104 outputs a time-up signal to the information analysis unit 103.

In addition, the CPU 104 controls the speaker control unit 109 to cause the speaker unit 113 to output a ring tone or the like.

Next, the operation of the text communication by the wireless communication terminal device according to the first embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation on the receiving side in the telephony communication. FIG. 3 is a flowchart showing the operation of the transmitting side in the text communication. FIG.
FIG. 3 is a sequence diagram of a text call including a transmitting side and a receiving side. In the following description of the operation, it is assumed that the user 1 is on the receiving side and the user 2 is on the transmitting side with respect to the two parties performing the text communication.

In FIG. 1 and FIG. 2, first, in order to perform a text call communication, the user 1 and the user 2 operate the man-machine interface unit 112 of each wireless communication terminal device (hereinafter referred to as “mobile terminal”). A connection procedure is performed for the network (S202). In the mobile terminal of the user 1 waiting for data reception (S203), when the first data is received (S204), the information analysis unit 103 analyzes whether the received data is a control code or a message. This is performed (S205).

If it is determined that the received data is a message, it is stored as a received message in the text communication work area 108 and displayed on the display unit 110 (S2).
06), and waits for reception from the user 2 (S203).
In this case, the information analysis unit 103 includes the transmission control unit 105
Since the prohibition instruction is not issued to the operation system control unit 107, the key input operation can be performed at the mobile terminal of the user 1, and the text communication storage area 10 can be transmitted to the mobile terminal of the user 2.
8 is ready for transmission (S213).

On the other hand, if it is determined in S205 that the received data is a control code, the next message is currently being created in the mobile terminal of the user 2 on the transmitting side, so the information analyzing unit 103 Operation system control unit 107
To prohibit the key input operation (S207), and instruct the transmission control unit 105 to prohibit the transmission operation (S2).
08). As a result, the user 1 cannot perform a key input operation of the mobile terminal, and thus waits for a message to be received (S209).

At the same time, the CPU 104 starts the counter unit 106, counts the elapsed time after receiving the control code (S210), and manages the time-up of the counter unit 106 (S212).

When a message is received regardless of whether the counter unit 106 has timed out (S21).
1) The received second message is stored in the text communication work area through the control code determination (S205), and displayed on the display unit 110 (S206). At this time, the CPU 104 issues an instruction to release the prohibition to the information analysis unit 103, so that the prohibition of the key input and the data transmission is released at the mobile terminal of the user 1, and the user 1 can talk to the user 2 (S213). ).

On the other hand, when the second message is not received from the mobile terminal of user 2 (S211) and the time is up (S212), CPU 104 outputs a time-up signal to information analyzer 103. The information analysis unit 103 cancels the prohibition instruction issued to the transmission control unit 105 and the operation system control unit 107. As described above, if the second message cannot be received within the predetermined time despite receiving the control code, the mobile terminal of the user 1 is in a state where data input and data transmission can be performed (S213). .

Next, in FIG. 1 and FIG. 3, first, in order to perform a text call communication, the user 1 and the user 2 operate the man-machine interface unit 112 of each mobile terminal to perform a connection procedure to the network. Perform (S302). The user 2 inputs a message from the man-machine interface unit 112 of the mobile terminal to transmit a message to the user 1 (S303), and after the input of the first sentence is completed, transmits the message to the user 1 (S303). S304). At that time, the CPU 104 measures the time from the transmission of the message by the counter unit 106 to the input of the next message (S306).

After the data is transmitted, the process waits for a data input from the man-machine interface unit 112 (S30).
5) If there is no input of the second message (S307), a state where the processing of receiving a message from the user 1 and the like can be performed (S312).

On the other hand, when the second message is input (S
307), and when the input of the second message is within the time-up time (S308), the information analysis unit 10
3 generates a control code in response to an instruction from the CPU 104 and causes the wireless unit 102 to transmit the control code to the mobile terminal of the user 1 on the receiving side (S309).

As a result, the user 2 can notify the user 1 that the next message is being input. The mobile terminal of the user 1 is prohibited from performing a message input operation and a transmission operation, and is in a state of waiting for a message from the mobile terminal of the user 2. When the input of the second message is completed (S310), the CPU 104 performs transmission processing of the second message (S311), and waits for data input (S305).

As described above, when the user 2 transmits the second message within a certain time after the transmission of the first message, the user 2 can reliably perform a series of text calls without any interruption from the user 1. Can be.

On the other hand, if the input of the second message is after the time-up, the CPU 104
03 is not instructed to create a control code, the second message is sent after the second message has been input (S311), and the process waits for data input (S30).
5). In this case, the mobile terminal of user 1 is in a state where message transmission is possible because the control code is not received.

Next, FIG. 4 shows a sequence in a case where the mobile terminal 1 of the user 1 makes a call to the mobile terminal 2 of the user 2 via the communication channel of the network to perform a text communication. Note that it is assumed that a message is transmitted after a message is input and a return code (here, “CR + LF”) is input.
) Is input.

In FIG. 4, first, user 1 and user 2
Establishes a communication path via a network for text communication between the two parties (A). Specifically, the user 1 transmits a communication registration request 401 from the mobile terminal 1 to the network. The network sets a communication channel and transmits a communication registration request 407 to the mobile terminal 2 of the user 2. On the other hand, the mobile terminal 2 transmits a communication registration response 408 to the network, and the network transmits a communication registration response 402 to the mobile terminal 1. As a result, a communication channel between the mobile terminals 1 and 2 is set in the network, and a communication path via the network is established.

Next, a message 1 for the user 2 is input from the mobile terminal 1 of the user 1 (B). As a result, message 1 “ABC (CR + LF)” 403 is transmitted to the network. The mobile terminal 2 receives a message 1 from the network.
“ABC (CR + LF)” 409 is received and displayed.
User 2 can check the contents of message 1.

At this time, it is assumed that the user 1 starts inputting the next message, Message 2, to the mobile terminal 1 (C). If the time from the transmission of the message 1 to the start of the input of the message 2 is shorter than the set time, the control code (here, for example, “＠＠
４０４) 404 is transmitted. The mobile terminal 2
The control code "$" 410 is received from the network. As a result, the mobile terminal 2 is in a state of not accepting the input operation of the user 2. Further, the mobile terminal 2 is also in a state where it cannot transmit a message that has been captured before receiving the control code (D). User 2 and mobile terminal 2 send message 2
Wait for reception.

Next, when the user 1 completes the input of the message 2 to the mobile terminal 1 (E), the mobile terminal 1 sends a message 2 “DEFG (CR + LF)” 4 to the network.
05 is transmitted. The mobile terminal 2 sends a message 2 from the network.
“DEFG (CR + LF)” 411 is received.

As a result, in the mobile terminal 2, the message input operation and the message transmission are permitted (F).
The user 2 can input the message 3 to the mobile terminal 2 (G). The mobile terminal 2 receives the message 3
“HI (CR + LF)” 412 is transmitted to the network.
The mobile terminal 1 sends the message 3 "HI (CR + L
F) ”406 is received and displayed. The user 1 can check the contents of the message 3.

Next, a radio communication terminal according to a second embodiment of the present invention will be described. The wireless communication terminal device according to the present embodiment has the same configuration on the transmitting side as in the first embodiment, except that the receiving side omits the counter unit 106 and the operation system control unit 107 in the first embodiment. Become. Therefore, since the description can be made with reference to FIG. 1, the configuration diagram is omitted in the second embodiment.

In the present embodiment, the CPU 104 at the time of reception
However, when receiving a control code reception notification from the information analysis unit 103, the transmission side displays on the display unit 110 that the next message is being input, and dissuades the user from watching the display to discourage key input operation. I have to.

Therefore, the transmitting side transmits the control code in the same manner as in the first embodiment, but does not expect the receiving side to wait for reception. In other words, in the second embodiment, the speaker notifies the listener that his or her conversation has not been completed by the control code. However, the speaker can interrupt the conversation or wait for reception by checking the display screen. It is up to the discretion of both the talker and the listener.

The operation of the wireless communication terminal according to the second embodiment will be described below with reference to FIGS. FIG.
It is a flowchart which shows the operation | movement of the receiving side in text telephone communication. FIG. 6 is a flowchart showing the operation of the transmitting side in the text communication.

In FIG. 1 and FIG. 5, first, in order to perform a text call communication, the user 1 and the user 2 operate the man-machine interface unit 112 of each wireless communication terminal device (hereinafter referred to as “mobile terminal”). A connection procedure is performed for the network (S502). In the mobile terminal of the user 1 waiting for data reception (S503), when the first data is received (S504), the information analysis unit 103 analyzes whether the received data is a control code or a message. This is performed (S505).

If it is determined that the received data is a message, it is stored as a received message in the text communication work area 108 and displayed on the display unit 110 (S5).
06), and waits for reception from the user 2 (S503).

On the other hand, if it is determined in step S505 that the received data is a control code, the mobile terminal of the user 2 on the transmitting side is currently creating the next message, and the CPU 104 Upon receiving the control code reception notification from the terminal 103, the display unit 110 performs a display process indicating "input of user 2" (S507), and notifies the user 1. The user 1 on the receiving side stops watching the transmission operation after watching the display.

At the same time, the CPU 104
Is started, the time after receiving the control code is counted (S508), and the time up of the counter unit 106 is managed (S512). The CPU 104 receives the second message from the mobile terminal of the user 2 (S50).
9) Irrespective of whether the time is up or after the time up, the display of "input of user 2" on the display unit 108 is turned off (S510), and the message 2 is stored in the text communication work area 107. Is displayed on the display unit 110 (S511), and the received second message is stored and displayed in the text communication work area 108 (S511).

Since the user 1 receives the second message from the user 2 and thereafter does not display the message "input of the user 2", the user 1 determines that the user 2 has no intention to transmit, and transmits a message to the user 2. (S5
14).

On the other hand, if the second message is not received from the mobile terminal of user 2 within the time-up time (S509, S512), CPU 104 turns off the display of "input of user 2" on display unit 108 (step S509). S513). Since the user 1 has received the control code but has not received the second message, the user 1 determines that the user 2 has stopped transmitting and the user 2
(S514).

Next, in FIG. 6, first, in order to perform a text communication, the user 1 and the user 2 operate the man-machine interface unit 112 of each mobile terminal and perform a connection procedure to the network (S602). ). The user 2 inputs a message from the man-machine interface unit 112 of the mobile terminal in order to transmit the message to the user 1 (S603).
The message is transmitted to (S604).

After the data transmission, the process waits for data input from the man-machine interface unit 112 (S60).
5) If there is no input of the second message (S606), a state where a process of receiving a message from the user 1 and the like can be performed (S610).

On the other hand, when the second message is input (S
606), the information analysis unit 103 generates a control code in response to the instruction of the CPU 104, and causes the wireless unit 102 to transmit the control code to the mobile terminal of the user 1 on the receiving side (S60).
7).

Thus, the user 2 can notify the user 1 that the next message is being input. The mobile terminal of the user 1 is prohibited from performing a message input operation and a transmission operation, and is in a state of waiting for a message from the mobile terminal of the user 2. Upon completion of the input of the second message (S608), the CPU 104 performs transmission processing of the second message (S609), and waits for data input (S605).

As described above, when transmitting the second message after transmitting the first message, the user 2
It can be expected that a series of text calls can be performed without gaps without interruption from the Internet.

Here, the present invention is not limited to the first and second embodiments, and various modifications are possible. For example, in the first embodiment, the prohibition of the input operation and the prohibition of the transmission operation are performed simultaneously, but at least the prohibition of the input operation is sufficient. This is because the prohibition of the transmission operation is a secondary measure.

As for the receiving operation, the first embodiment and the second embodiment may be used in combination. First
In this embodiment, it is not clear why the operator does not accept the information, and the operator may feel uncomfortable. On the other hand, in the second embodiment, since only the display is performed, there is a lack of certainty. If used together, the mutual disadvantages are compensated, and interruption on the receiving side can be reliably prevented.

[0055]

As described above, according to the present invention,
Since the messages are transmitted alternately, the speaker and the listener in the conversation can be clearly divided, and the text communication between the two parties can be performed smoothly.

Also, according to the present invention, the receiver can recognize that the other party is continuing to input and transmit a message after transmission, and can determine that the other party has stopped transmitting the message. In a text call, it is possible to determine the call situation of the other party to some extent.
