DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable communication device, and more particularly, to a portable communication device having a data communication function such as a facsimile function.

[0002]

2. Description of the Related Art Conventionally, as a portable mobile communication device, a mobile phone for making a call and the like have been known. Here, in mobile communication, the state of the transmission path fluctuates from moment to moment,
In particular, there is a problem that data errors and data loss are likely to occur due to fading that deteriorates transmission quality. To cope with these problems, an error retransmission method (detection retransmission method), an error correction method, a continuous transmission method, a return matching method, and the like are known.

Here, the error retransmission method is a method in which a reception side checks for the presence or absence of an error and requests the transmission side to retransmit only an error portion. In the error correction method, a check bit is added to a transmission signal on a transmission side, and an error is corrected on the reception side using the check bit. In addition, the continuous transmission method is to repeatedly transmit a transmission signal a plurality of times, and further, the return collation method is to return the received transmission signal to the transmission side as it is, and check whether the signal returned by the transmission side is correct. It checks whether or not it is not correct, and if it is not correct, transmits the transmission signal again.

[0004]

However, in the above-mentioned error retransmission system, continuous transmission system and return collation system, there is a problem that the communication time increases, and as a result, the communication cost increases. In particular, the continuous transmission method cannot check the received signal on the receiving side, and thus has a problem in the reliability of the transmitted signal. In the error correction system, a circuit configuration for generating a check bit is required on the transmission side, and a circuit configuration for correcting and detecting an error is also required on the reception side. Requires configuration. Further, as described above, a step of generating check bits on the transmitting side and a step of performing check on the receiving side are required, so that there is a problem that it takes time. further,
In order to increase the error correction capability, a large number of check bits are required, and the amount of information to be communicated is enormous, and the communication time is increased.

In recent years, digital mobile communication services have been started, and it is conceivable that demand for data communication such as images in mobile communication will increase in the future. Here, in the case of data communication, the effect of fading is greater than in the case of telephone communication. In other words, in the case of a telephone call, the other party's voice is interrupted and the call is not impossible at all. However, in the case of data communication, there is a problem that predetermined data is lost and desired data cannot be obtained. is there. Therefore, an object of the present invention is to provide a portable communication device that can prevent the effects of fading and reduce the deterioration of transmission quality.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a portable communication device A according to the present invention includes an antenna 10, a radio control unit 12, a data communication control unit 14, and a main control unit 16.
And a display unit 18 and an input unit 20.

Here, the wireless control unit 12 controls a wireless system, is in charge of wireless communication with a base station, a master unit, and other terminals, and determines whether it is data communication or telephone communication. If it is determined that the call is a call, the line is switched to a receiver (not shown) to enable a call between the users. Further, the data communication control unit 14 controls data communication. Here, the data communication refers to communication of character information, image information, other information, and the like, and ordinary calls are not included in the data communication. The data communication includes data communication using an audio signal path typified by G3 facsimile and data communication using a digital signal path typified by G4 facsimile.

The main control section 16 controls the operation of each section of the portable communication device A. The main controller 16 is provided with a ROM (not shown).
The OM stores information on a movement prohibition guide image (hereinafter, referred to as a “guide image”) that indicates that movement is prohibited.

The display section 18 is for displaying characters and figures, and has a display section as a display screen composed of LCDs and LEDs, and a display section for displaying on the display section. RAM. Further, the input unit 20 is for inputting dial numbers required for data communication and performing various operations, and is constituted by a transparent touch panel provided on the display unit of the display unit 18. That is, the display unit 18 displays an image resembling a dial key or various function keys of a conventional telephone, for example, and touches a position corresponding to a key displayed on each image of the input unit 20. The user can input dial numbers to be performed and information on various functions. Here, it is assumed that at least a data communication mode key for selecting a data communication mode, a dial key, and a start key for calling a dialed number are displayed. The display unit 18 and the main control unit 16 constitute notification means.

The operation of the portable communication device A having the above configuration will be described. First, the case where the portable communication device A is on the transmitting side will be described. When communicating data such as character information or image information, the data communication mode is selected by pressing the data communication mode key. Then, the input unit 2
The selection signal sent from 0 is sent to the main control unit 16 and also sent to the data communication control unit 14. It is assumed that data to be transmitted is stored in the data communication control unit 14 in advance.

When the number on the receiving side is dialed and the start button is pressed, the radio control unit 12 makes a call, and the radio control unit 12 sends information indicating that the data communication is from the data communication control unit 14. And perform a pre-procedure for data communication. That is, transmission and reception of various signals are performed with the receiving side to perform data communication. After completing the pre-procedure,
The wireless control unit 12 transmits the data sent from the data communication control unit 14 to the receiving side, and starts data communication (S20).
1).

Here, information that the pre-procedure has been completed and the data communication has been started is sent from the data communication control unit 14 to the main control unit 1.
When the main control unit 16 receives the information, the main control unit 16 transmits the information of the guide image to the display unit 18. The display unit 18 writes the information of the guide image in the RAM and causes the display unit to display the guide image (S202).

Here, the guide images are shown in FIGS.
(D) are shown, and any of these will be displayed. Here, FIG. 3A and FIG.
The guide image shown in (b) is shown in Japanese, and displays "Do not walk during data transmission" and "Transmission errors are more likely to occur when walking". The guidance image shown in FIG. 3 (c) is shown in English and “Don't
Walk! Is displayed. Further, the guide image shown in FIG. 3D is composed of a graphic indicating movement prohibition, and the portable communication device A can be used even for a person who cannot understand characters.
Can be understood that must not be moved.
Although the description has been made assuming that any one of the guide images shown in FIGS. 3A to 3D is displayed, a Japanese image (FIG.
(A), (b)), an English image (FIG. 3 (c)) and a graphic image (FIG. 3 (d)) are displayed periodically one after another so that the user can easily understand the displayed contents. You may make it.

By displaying the guide image as described above, the user can know that the portable communication device A must not be moved. By refraining from walking, it is possible to prevent the effects of fading in data communication.

Next, during the data transmission, the above guide image is kept displayed. When data is transmitted while displaying the data being transmitted, the data may be displayed in the form of a window at a corner of a display screen or the like. When the data transmission ends and the data communication ends, the display of the guide image is deleted from the display unit (S203, S20).
4). That is, before the data transmission is completed and before the processing of the post-procedure is performed, the data communication control unit 14 detects that the data communication is completed, and sends the detection information to the main control unit 16. The main control unit 16 receives the detection information and controls the operation of the display unit 18 so that the display on the display unit 18 is turned off. Then, so-called post-procedure processing is performed with the receiving side, and then the line is disconnected. That is, if the data communication is completed and before the post-procedure is performed, there is no possibility of data loss due to fading, and the display is erased at this point.

In the above description, the guide image is displayed when the pre-procedure in the data communication is completed, and the display of the guide image is deleted before the post-procedure is performed. Is not limited. For example, as the display timing, the guidance image may be displayed when the data communication mode key is selected by pressing the data communication mode key, or displayed when the start button is pressed when making a call. May be performed. In these cases, when the key operation or the button operation is performed on the input unit 20, the main control unit 16 detects the operation and controls the operation of the display unit 18 to perform the display. That is, since it is known that the data communication is performed when the data communication mode is selected, the display may be performed at this time.

The display may be turned off when the line is disconnected. In this case, information indicating that the line has been disconnected is sent from the wireless control unit 12 to the main control unit 16, and the main control unit 16 controls the operation of the display unit 18 to turn off the display. In other words, when the effect of fading is to be prevented even in a post-procedure performed after the end of data communication, display is performed during this time. In addition, when performing transmission while displaying transmission data on the screen of the display unit 18, in order to effectively utilize the screen,
Even during transmission, the display may be turned off after a predetermined time has elapsed.

Next, a case where the portable communication device A is on the receiving side will be described. When there is an incoming call to the portable communication device A, the wireless control unit 12 sends information to that effect to the main control unit 16. Further, in the wireless control unit 12,
It is determined whether the incoming call is a data communication or a call. In the case of a call, the main control unit 1 receiving the information to that effect
Reference numeral 6 denotes a communication circuit (not shown) which controls a communication circuit connected to a microphone and a speaker to enable communication.
On the other hand, in the case of data communication, a pre-procedure for data communication is performed with the transmitting side. After completing the pre-procedure,
The wireless control unit 12 receives data transmitted from the transmission side and starts data communication (S201).

Here, information indicating that the pre-procedure has been completed and the data communication has started is transmitted from the data communication control unit 14 to the main control unit 1.
When the main control unit 16 receives the information, the main control unit 16 transmits the information of the guide image to the display unit 18. The display unit 18 displays the guide image as in the case of the transmission side (S20).
2). The guide image on the receiving side is the same as that on the transmitting side, and one of the images shown in FIGS. 3A to 3D is displayed. As in the case of the transmitting side, the display in Japanese, the display in English, etc. may be periodically displayed one after another.

As described above, the guide image is displayed, so that the user can know that the portable communication device A must not be moved, as in the case of the transmission side, and the influence of fading. Can be prevented.

Next, during data reception, the above-mentioned transfer prohibition image is kept displayed. When receiving data while displaying the data being received, the data may be displayed in the form of a window at a corner or the like of a display screen. When the data reception ends and the data communication ends, the display of the guide image is erased (S203, S204). That is,
Before the data reception is completed and the above post-processing is performed,
The data communication control unit 14 detects that the data communication has ended, and sends detection information to the main control unit 16. Main control unit 1
6 controls the operation of the display unit 18 so as to turn off the display on the display unit 18 in response to the detection information. Then, a process in a so-called post-procedure is performed with the transmitting side, and then the line is disconnected. That is, the display is turned off before the post-procedure is performed after the data communication ends.

In the above description, the guide image is displayed when the pre-procedure in the data communication is completed, and the display of the guide image is erased before the post-procedure is performed. Not limited. For example,
As the display timing, a guide image may be displayed at the time of receiving a call. In other words, in the case of the digital communication system, it is possible to determine whether the communication is a data communication or a telephone call at the time of receiving a call. Also, in the case of a method of modulating data into a voice band instead of a digital communication method, the data communication can be determined by judging whether the data communication or the telephone call after an incoming call. It may be performed. In these cases, when a call is received by the wireless control unit 12, when the wireless control unit 12 determines that data communication is to be performed, the main control unit 16 detects this and controls the display unit 18 to operate. Will be displayed.

The display may be turned off when the line is disconnected. In this case, information indicating that the line has been disconnected is sent from the wireless control unit 12 to the main control unit 16, and the main control unit 16 controls the operation of the display unit 18 to turn off the display. Also, when performing reception while displaying the reception data on the screen of the display unit 18,
In order to use the screen effectively, the display may be turned off after a predetermined time has elapsed even during reception.

In the above description, the guide image is displayed in the case of data communication.
Display may be performed not only in the case of data communication. In other words, the above display is performed even when a call is made, so that the effect of fading is prevented. As a specific display timing, in the case of the transmitting side,
The display may be performed when the start button is pressed at the time of calling, or when the call mode selection button is pressed at the time of a call, the display may be performed at the time the button is pressed. In the case of the receiving side, it may be displayed at the time of the incoming call. Further, the display is erased when the line is disconnected.

In the above embodiment, the guide image is displayed on the display unit 18. However, a lamp such as an LED (not shown) is provided in the portable communication device A, and the lamp is turned on to move the guide image. The prohibition may be notified. Accordingly, the screen of the display unit 18 can be widely used, and the user can stop the portable communication device A to prevent the influence of fading, thereby performing the data communication smoothly. This lamp constitutes notification means.

In the above description, the movement prohibition is visually notified, but the movement prohibition may be notified by sound or voice. That is, FIG.
A sound indicating the contents of (a) to (c) is output, or a dedicated ringing tone is sounded to notify movement prohibition. Here, in the case of outputting sound, it is conceivable that the sound of the announcement is output by the sound output unit and output from the speaker used for the call, but it is conceivable that the handset is not put on the ear. It is desirable to increase the volume so that it can be heard even when the receiver is at hand. Further, when a dedicated ringing tone is sounded, a ringing tone output section for outputting the ringing tone is provided.

Further, the user is informed in advance that the normal ringing tone also has the meaning of prohibition of movement, and the ringing tone output unit outputs the ringing tone at each timing described in the case of displaying the guide image. May output a normal ringing tone to notify that movement is prohibited. here,
The sound output unit, the speaker, and the ringing sound output unit constitute notification means.

As a result, the movement prohibition can be notified audibly, and the user can stop the portable communication device A to prevent the influence of fading, thereby enabling smooth data communication. In particular, when the display unit of the display unit 18 is not visually recognized, the notification can be reliably performed. The speaker and the ringing sound output section constitute a sound output section.

The display of the guide image, the turning on of the lamp, and the notification of sound or voice are appropriately combined to notify the user of the movement prohibition, so that the user is securely informed of the prohibition of the movement. be able to. In the above description, the configuration of the display unit 18 and the input unit 20 has been described on the assumption that the transparent touch panel is provided on the display unit configured by the LCD, but the present invention is not limited to this. The input unit 20 may be a key input unit provided at a different position from the display unit.
