Abstract

PROBLEM TO BE SOLVED: To provide a mobile communication device which will not continue to monitor a line state wastefully, and to efficiently transmit data. SOLUTION: This mobile communication device temporarily stores unsent data (S4), if line quality becomes worse (YES in S1), and informs a user that the line is possibly broken and makes user select an automatic continuing process or a temporary stop process for stopping the data transmission, while the unsent data are temporarily stored as a subsequent process (S5). The mobile communication device carries out the automatic continuing process or temporary stop process that the user indicates (S6 to S10). Consequently, the line state is prevented from being monitored wastefully, while the user is not aware. Furthermore, while the unnecessary monitoring of the line state is prevented, data having been sent are prevented from being sent again, so that the data transmission can efficiently be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication device applied to a mobile communication system represented by a terrestrial mobile phone system and having a data transmission function.

[0002]

2. Description of the Related Art Hitherto, there has been known a mobile communication system having a mobile station (mobile communication device) and a base station, and transmitting and receiving a radio communication signal between the mobile station and the base station via a communication channel. . This mobile communication system generally targets not only voice but also data. That is, the mobile station according to the mobile communication system divides a series of data into a plurality of unit data, includes each unit data in a radio communication signal, and transmits the burst data.

By the way, when a mobile station enters, for example, behind a building, it becomes impossible to receive a radio communication signal at a good level. In this case, if the reception level drops to a level at which communication is not possible, the communication channel is automatically disconnected even during communication. Therefore,
Communication cannot be achieved completely.

A technique for coping with this is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-22908. According to the technology disclosed in this publication, the mobile station measures the electric field strength of the received wireless communication signal, and if the measured electric field strength is at a level at which communication is not possible, the mobile station temporarily suspends data transmission. The transmission data is temporarily stored. Thereafter, the mobile station repeats the measurement of the electric field strength, and when the electric field strength recovers to a communicable level, automatically starts transmitting the stored untransmitted data.

[0005]

However, according to this technique, the user of the mobile station is not particularly informed that the monitoring of the line status is automatically repeated, so that the user of the mobile station interrupts the data transmission. Can't tell if it's done or it's done. That is, the line state monitoring process is continued without the user of the mobile station being conscious. Therefore, it is expected that the user of the mobile station will not consciously move to a place with good line conditions. In this case, data transmission will not end even after a long time.

To cope with this, for example, Japanese Patent Application Laid-Open No. 8-88
As disclosed in Japanese Patent Publication No. 02, the configuration in which when a communication line is likely to be automatically disconnected, the user of the mobile station is notified of the possibility of disconnection is applied to the above technology. Can be considered. However, even if the user of the mobile station can know that there is a risk of a line disconnection, there is no substitute for continuing to monitor the line state after the line disconnection. On the other hand, when it takes time to move to a place where the line condition is good, such as when entering a large building or driving on a mountain road by a vehicle, the user of the mobile station waits for a while before communicating. It is expected that they will resume. In this case, continuing the line state monitoring process is useless.

To eliminate this waste, the user of the mobile station must turn off the power. However,
When the power is turned off, the temporarily stored data is erased, so that the next time communication starts, the transmitted data must be transmitted again. Therefore,
The communication time becomes longer than necessary and data transmission becomes inefficient. Therefore, sufficient services cannot be provided to the user.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mobile communication device capable of efficiently performing data transmission without continuing useless line state monitoring processing.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a transmitting means for transmitting a series of data in bursts for each of a plurality of unit data, and a radio link based on a signal received from a base station. Line status monitoring means for monitoring the status of the wireless communication line, and automatic continuation processing for automatically continuing data transmission by the transmission means when the line status monitoring means determines that the state of the wireless line is degraded. Notification means for notifying the user to select any of the suspension processing for temporarily stopping data transmission in a state in which the data is temporarily stored, and a user operation in response to the notification of the notification means, Instruction means for instructing which of the automatic continuation processing and the pause processing is to be selected;
The present invention relates to a mobile communication device that includes a user interface unit that controls the transmission unit in accordance with a process instructed by the instruction unit.

[0010]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Embodiment 1 FIG. 1 is a conceptual diagram showing a configuration of a mobile communication system to which a mobile communication device according to Embodiment 1 of the present invention is applied.
This mobile communication system is a terrestrial mobile phone system, has a mobile communication device 1 and a base station 2, and realizes mobile communication by transmitting and receiving wireless communication signals between the mobile communication device 1 and the base station 2. I do.

[0012] More specifically, the mobile communication system targets voice and data. The data includes character data and image data. That is, this mobile communication system has a relatively large capacity (for example, 2 Mbytes).
Can be handled. When communicating a large amount of image data, the mobile communication device 1 and the base station 2 according to the mobile communication system divide the image data into a plurality of unit data and transmit each unit data in a burst.

FIG. 2 is a block diagram showing the configuration of the mobile communication device 1. The mobile communication device 1 includes a mobile phone and the like. Further, the mobile communication device 1 may be configured by a combination of a portable computer and a portable wireless communication device.

The mobile communication device 1 includes a man-machine interface device 10 and a control device 20. The user of the mobile communication device 1 is a man-machine interface device 1
0, various instructions are given to the control device 20, and the control device 20 gives various information to the user via the man-machine interface device 10.

More specifically, the man-machine interface device 10 includes a small camera 11, a display unit 12, and an operation unit 13. The small camera 11 outputs the captured image (still image) to the control device 20 as image data. The display unit 12 includes a liquid crystal display element (LCD), an electroluminescence element, and the like, and displays menu information from which various information can be selected, character information such as e-mail, image information, and the like. The operation unit 13 includes a power key 14 (power-off instruction means) for inputting power on / off, a numeric keypad 15 for inputting numbers and characters, and a scroll key 16 (instruction for moving a cursor displayed on the display unit 12). Means). Key output signals from the keys 14 to 16 are output to the control device 20.

The control device 20 includes a transmission / reception unit 21, a line quality detection unit 22, a line state monitoring unit 23, and a control unit 24. The transmission / reception unit 21 transmits and receives a control signal to and from the base station 2 via a control line, and transmits and receives a radio communication signal to and from the base station 2 via a communication line. More specifically, the transmission / reception unit 21 generates a control signal such as a call signal including a destination telephone number and a response signal including local identification information, and transmits the generated control signal via a control line. To the base station. Further, the transmitting / receiving unit 21 creates a wireless communication signal including the communication data provided from the control unit 24, and transmits the created wireless communication signal to the base station 2 via a communication line.

Further, the transmitting / receiving section 21 receives a call signal including call information, a control signal represented by a base station signal including a base station identification number, and a radio communication signal including communication data. Furthermore, the transmitting / receiving unit 21 extracts control information such as incoming call information and a base station identification number from the received control signal, and also extracts communication data from the wireless communication signal. The transmitting / receiving unit 21 provides the control unit 24 with the extracted control information and communication data. Further, transmitting / receiving section 21 provides the received control signal and wireless communication signal to channel quality detecting section 22.

The line quality detecting section 22 detects the line quality based on the given control signal and radio communication signal. More specifically, line quality detecting section 22 detects the received electric field strength of the received control signal as the quality of the control line. Further, the line quality detection unit 22 detects the reception electric field strength of the received wireless communication signal as the quality of the communication line. The line quality detection unit 22 gives the detected reception electric field strength to the line state monitoring unit 23.

The line state monitoring unit 23 monitors the line state based on the received received electric field strength. More specifically, the line state monitoring unit 23 compares the received electric field strength with a preset threshold value, and determines whether the received electric field strength has fallen below the threshold value. The above threshold value corresponds to the limit of the received electric field strength at which good communication cannot be performed. When the received electric field strength falls below the threshold value, the line state monitoring unit 23 sends the quality deterioration signal to the control unit 2.
Give to 4.

The control section 24 functions as a control center of the control device 20. The control unit 24 includes a notification unit 24a and a user interface unit 2 as functional blocks.
4b, a transmission control unit 24c and a temporary storage unit 24d. In this embodiment, the transmission control unit 24c and the transmission / reception unit 21 correspond to a transmission unit. Notification unit 2
4a and the display unit 12 of the man-machine interface device 10 correspond to a notification unit.

The notifying unit 24a notifies the user of the quality of the control line and the communication line, and notifies the user to select two processes when the line quality is deteriorated. User interface unit 24
b controls the data transmission in the transmission control unit 24c according to the quality of the control line and the communication line. The transmission control unit 24c executes connection / disconnection of a communication line by transmitting / receiving control information via a control line. Further, the transmission control unit 24c creates communication data and gives the created communication data to the transmission / reception unit 21 at a predetermined timing. The temporary storage unit 24d
This is for temporarily storing communication data created by the transmission control unit 24c as necessary.

Notification section 24a, user interface section 2
4b and the transmission control unit 24c are constituted by, for example, software executed by the CPU. The temporary storage unit 24
d is constituted by hardware such as a RAM, for example. In this case, the condition is that the temporary storage unit 24d unconditionally erases the stored contents when the power of the mobile communication device is turned off.

More specifically, the transmission control unit 24c
Communication data is created based on the data output from the man-machine interface device 10. In particular, when a large amount of image data is output, the transmission control unit 24c
The image data is divided into a plurality of unit data, and each unit data is used as communication data. The transmission control unit 24c gives the created communication data to the transmission / reception unit 21 at a predetermined timing. The transmission control unit 24c may generate the burst data based on, for example, image data or the like stored in advance in the control unit 24 in addition to the data output from the man-machine interface device 10. Of course.

FIG. 3 is a flowchart for explaining data transmission control in the mobile communication device 1. This transmission control is started in response to a communication line being connected to the base station 2 in the transmission control unit 24c and data transmission via this communication line being started. The user interface unit 24b determines whether or not the quality of the communication line has deteriorated based on whether or not the quality deterioration signal has been given (step S1).

When no quality degradation signal is given, the quality of the communication line can be considered to be stable.
The transmission permission is given to c. The transmission control unit 24c starts giving communication data to the transmission / reception unit 21 in response to the transmission permission being given. Thus, data transmission is started (step S2).

Thereafter, the user interface unit 24b
Monitors the data transmission in the transmission control unit 24c and determines whether the data transmission is completed (step S
3). When the data transmission ends, the user interface unit 24b ends this processing. If the data transmission has not been completed, the user interface unit 24b proceeds to step S1, and executes the line quality determination process again.

In step S1, when a quality deterioration signal is given, the quality of the communication line can be considered to be deteriorated.
The untransmitted data is stored in the temporary storage unit 24d (step S4), and the data transmission is suspended. Thereafter, the user interface unit 24b notifies the notifying unit 24a that the quality of the communication line is degraded.

In response to this, the notifying section 24a prompts the user for the possibility that the communication line may be forcibly disconnected and for the user to select either the automatic continuation processing or the temporary stop processing as the subsequent processing. Notify (Step S
5). More specifically, the notification unit 24a gives the above-described notification contents to the display unit 12. The display unit 12 displays a message to the effect that the communication line may be disconnected on the display screen. After this display, the display unit 12 displays on the display screen a message indicating which of the automatic continuation process and the pause process is to be selected.

When the user sees this display, he selects the automatic continuation processing or the temporary stop processing. More specifically,
The display unit 12 displays menu information on the display screen so that one of the automatic continuation process and the pause process can be selected. The user selectively indicates one of the menu information by operating the scroll key 16 of the operation unit 13 (step S6). When the selection instruction is performed, the operation unit 13 gives the control unit 24 a command signal including identification information of the automatic continuation process or the temporary stop process.

On the other hand, the user interface unit 24b
Until a command signal is provided from the operation unit 13, it is determined whether or not a command signal is provided (Step S)
7). When the command signal is given, the user interface unit 24b determines which of the automatic continuation process and the pause process has been selected (step S8). When the automatic continuation process is selected, the user interface unit 2
4b executes an automatic continuation process (step S9). On the other hand, when the pause processing is selected, the user interface unit 24b executes the pause processing (Step S
10).

While the above processing is being performed in the user interface unit 24b and the like, if the quality of the communication line further deteriorates, the transmission control unit 24c forcibly disconnects the communication line. Become.

FIG. 4 is a flowchart for explaining the automatic continuation processing. User interface unit 24b
First, it is determined whether or not the line state has recovered to a predetermined state or higher. More specifically, the user interface unit 24b monitors the signal output from the line state monitoring unit 23 and determines whether or not the line quality has recovered to a predetermined quality or higher (step T1). Specifically, the user interface unit 24b determines that the line quality has been restored to the predetermined quality or higher when the quality deterioration signal is not provided from the line state monitoring unit 23 for a predetermined time. The line quality in this case corresponds to the quality of the communication line if the communication line is not disconnected, and corresponds to the quality of the control line if the communication line is disconnected.

The user interface unit 24b repeatedly executes the process of step T1 until the line quality is restored to a predetermined level or higher. As a result, when it is determined that the line quality has recovered to the predetermined quality or higher, the user interface unit 24b instructs the transmission control unit 24c to restart data transmission (step T2). In response to this, if the communication line is disconnected, the transmission control unit 24c reads the untransmitted communication data from the temporary storage unit 24d after re-establishing the communication line, and reads the read communication data. Is given to the transmission / reception unit 21. Thus, the transmission of the untransmitted communication data is automatically restarted.

Thereafter, the user interface unit 24b
Moves to step S1 in FIG. 3, and repeatedly executes the operation described with reference to FIG. Here, step T
The reason for shifting to step S1 instead of 1 is that even if the line quality once improves during the execution of the automatic continuation processing, there is a possibility that the communication line will be degraded enough to be forcibly disconnected thereafter.

FIG. 5 is a flowchart for explaining the temporary stop processing. User interface unit 24b
Determines whether a predetermined period of time has elapsed since the start of the suspension process (step U1). After a lapse of a predetermined time, the user interface unit 24b executes the same processing as the automatic continuation processing shown in FIG. 4 (steps U2 and U3).

That is, the user interface unit 24b
Monitors the signal output from the line state monitoring unit 23,
It is repeatedly determined whether or not the line quality has recovered to a predetermined quality or higher (step U2). When the line quality has recovered to a predetermined level or higher, the user interface unit 24b instructs the transmission control unit 24c to restart data transmission. In response, the transmission control unit 24c reads untransmitted communication data from the temporary storage unit 24d, and provides the read communication data to the transmission / reception unit 21. Thus, the transmission of the untransmitted communication data is automatically restarted (step U
3).

As described above, according to the first embodiment, when the line quality deteriorates, the user can select the automatic continuation processing or the temporary stop processing. Therefore, it is possible to prevent the automatic continuation process from being performed without being conscious. Therefore, it is possible to prevent a situation where it is not known whether the data transmission is completed. Therefore, there is no need to force the user to uselessly wait.

In addition, since it is possible to select a pause process for stopping data transmission while temporarily storing untransmitted data, it is possible to prevent the automatic continuation process from being performed without turning off the power. Therefore, when data is restarted, only untransmitted data needs to be transmitted. for that reason,
Data can be transmitted more efficiently than when transmission is restarted from transmitted data. Therefore, the service for the user can be improved.

Further, since the execution of the automatic continuation processing without the user being conscious can be avoided, unnecessary increase in traffic can be avoided.

Further, when the automatic continuation process is selected, the user is notified of the fact that the line quality has not recovered to the predetermined quality or more until the data transmission is restarted for the first time. And try not to. Therefore, no extra burden is imposed on the user.

Embodiment 2 FIG. 6 is a flowchart for explaining a temporary stop process in a mobile communication device according to Embodiment 2 of the present invention.

In the first embodiment, when the temporary stop process is selected, the same process as the automatic continuation process is executed unconditionally after a certain time has elapsed. On the other hand, in the second embodiment, when the pause process is selected, the user is asked whether or not to start transmission of untransmitted data after a predetermined time has elapsed. According to this configuration, the user is notified that the data transmission will be resumed after the selection of the suspension processing, so that the user can be made aware of the resumption of data transmission.

The temporary stop processing according to the second embodiment will be described in more detail. The user interface unit 24b determines whether a predetermined time has elapsed since the start of the suspension processing (step V1). After a lapse of a certain time, the user interface unit 24b notifies the notification unit 24a that the certain time has passed. In response,
The notifying unit 24a notifies the user whether to start transmitting untransmitted data (Step V2).

More specifically, notification section 24a instructs display section 12 to display a message asking whether to resume data transmission. In response to this instruction, the display unit 12 displays a message asking whether the restart is necessary on the display screen. On the other hand, the user uses the scroll key 16 of the operation unit 13 to instruct whether or not to resume (step V3). The operation unit 13 provides a command signal including identification information indicating whether or not restart is necessary to the user interface unit 24b of the control unit 24.

The user interface unit 24b determines whether or not a command signal has been received after asking whether the restart is necessary (step V4). When receiving the command signal, the user interface unit 24b determines whether or not to resume data transmission (step V5). If it is selected not to resume, the user interface unit 24b instructs the transmission control unit 24c to end the data transmission (step V6). The transmission control unit 24c deletes the untransmitted data stored in the temporary storage unit 24d according to the instruction. Thus, the data transmission ends.

On the other hand, if it is selected to resume data transmission, the user interface unit 24b instructs the transmission control unit 24c to start transmitting untransmitted data (step V6). Then, the user interface unit 2
4b, after repeatedly determining whether or not the line quality has recovered to the predetermined quality or higher (step V7), when the line quality has recovered to the predetermined quality or higher, instructs the transmission control unit 24c to start transmission of untransmitted data. (Step V8).

As described above, according to the second embodiment, the user is notified that the data transmission is to be resumed after the selection of the pause processing, so that the user can be made aware of the resumption of the data transmission. In addition, it is possible to satisfactorily cope with a case where the user temporarily selects the temporary stop processing and wishes to complete the process halfway. Therefore, the service to the user can be further improved.

Third Embodiment FIG. 7 is a flowchart for explaining a power-off instruction corresponding process according to a third embodiment of the present invention.

In the first and second embodiments, no measures are taken in the case where the power is about to be forcibly turned off by the user during data transmission. However, some users may not be able to reliably recognize whether or not data is currently being transmitted. In such a case, it is expected that some users will mistakenly think that the data transmission has already been completed and try to turn off the power. Therefore, in the third embodiment, when the user attempts to turn off the power during data transmission, the user is notified that data is being transmitted.

The power-off instruction corresponding processing according to the third embodiment is to be inserted immediately after step S3 in FIG. After determining that the data transmission has not been completed in step S3 of FIG. 3, the user interface unit 24b determines whether or not the user has instructed to turn off the power (step W1). If the power off has not been instructed, the process proceeds to step S1 in FIG.

On the other hand, if the power-off is instructed, the user interface unit 24b notifies the notification unit 24a that the power-off has been input. In response to this, the notification unit 24a notifies the user that data is being transmitted and whether to continue data transmission as it is (step W2). More specifically, the notification unit 24a instructs the display unit 12 to display a message corresponding to the content of the notification. In response to the instruction, the display unit 12 displays a message indicating that data transmission is being performed on the display screen, and then displays a message asking whether the data transmission is to be continued on the display screen. The user uses the scroll key 16 to select and instruct whether to continue data transmission (step W3). The operation unit 13 transmits a command signal including identification information indicating whether or not data transmission is required
To the user interface unit 24b.

The user interface unit 24b determines whether a command signal has been received (step W4).
When receiving the command signal, the user interface unit 24b determines whether to continue the data transmission based on the identification information of the command signal (step W5). When data transmission is continued, the user interface unit 24
b shifts to Step S1 of FIG. On the other hand, when ending the data transmission, the user interface unit 24b
After discarding the untransmitted data (step W6), power off of the mobile communication device 1 is permitted (step W7). In response, the circuit responsible for the power-off processing turns off the power of the mobile communication device 1.

As described above, according to the third embodiment, when the user instructs power off during data transmission,
The user is notified that data transmission is in progress, and is asked whether to continue data transmission as it is. Therefore, even if the user mistakenly thinks that data transmission has ended and turns off the power by mistake, data transmission can be continued. Therefore, the service for the user can be further improved.

Other Embodiments Embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, in the above embodiment, the user interface unit 24
b is a part of the function of the control unit 24. However, for example, the notification unit 24a and the user interface unit 24b
May be independent of the control unit 24, and may be configured as a hardware device different from the control unit 24.

In the above embodiment, the case where the present invention is applied to a terrestrial portable telephone system is described as an example. However, the present invention can be easily applied to a satellite mobile phone system that realizes mobile communication via a communication satellite.

[0056]

As described above, according to the present invention, when the line condition is deteriorated, the user can select the automatic continuation process or the temporary stop process. Can be prevented from being performed on its own. Therefore, it is possible to prevent a situation where it is not known whether the data transmission is completed. Therefore, there is no need to force the user to uselessly wait.

In addition, since it is possible to select a pause process for stopping data transmission while temporarily storing untransmitted data, it is possible to prevent the automatic continuation process from being performed without turning off the power. Therefore, when data transmission is resumed, only untransmitted data needs to be transmitted. Therefore, data can be transmitted more efficiently than when data transmission is restarted from transmitted data. Therefore, the service for the user can be improved.

Further, according to the present invention, when automatic continuation processing is selected, data transmission is resumed only after the line condition is restored. However, data can always be received with good quality.

Further, according to the present invention, no notification is given to the user until data transmission is resumed.
No extra burden on the user. Therefore, the service to the user can be further improved.

Furthermore, according to the present invention, data transmission is automatically resumed after the temporary stop processing is selected, so that data transmission can be completed without any extra work for the user. Therefore, the service to the user can be further improved.

Further, according to the present invention, the user is notified that the data transmission is to be resumed after the selection of the pause processing, so that the user can be made aware of the resumption of the data transmission. Therefore, it is possible to satisfactorily cope with the case where the user temporarily selects the suspension processing and wants to end the data transmission halfway. Therefore, the service to the user can be further improved.

Further, according to the present invention, even when the power-off is erroneously instructed during data transmission, the power-off is not permitted unless the stop of the data transmission is instructed. Therefore, even when the user mistakenly thinks that the data transmission has been completed during the data transmission and instructs to turn off the power manually, the data transmission can be continued as it is. Therefore, the service to the user can be further improved.
