Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone capable of executing a plurality of functions including a calling function.

[0002]

2. Description of the Related Art In recent years, mobile phones have been equipped with application programs that realize various functions such as schedule management, transmission / reception of text messages, and browsing of web pages, in addition to the call function. In the current mobile phones, these application programs are sequentially switched and executed.

Therefore, in the next-generation mobile phone, a multi-application function capable of executing a plurality of application programs in parallel has been proposed.

[0004]

Generally, an on-hook key is assigned as a key for ending an application program other than the call function. The on-hook key is originally installed in a mobile phone as a key for ending a call, but is recognized by a user as a “key for ending an operation”. Therefore, by assigning the on-hook key as a key for ending the function, it is possible to maintain the uniformity of the operation.

However, if an on-hook key is assigned as a key for terminating the application program,
It is assumed that the application program will be terminated unintentionally.

That is, when a call comes in while the application program is being executed, the call function is preferentially executed in the mobile phone, and the function being executed at the time of the call reception is also executed in parallel. When the user presses the on-hook key to end the call, the call function is ended and the previously executed application program is continuously executed as an active application. Here, if the on-hook key is mistakenly pressed twice at the end of the call, the call function is ended and then the application program that is being executed is also ended.

Cellular phones are often operated with one hand, and it is an easily assumed misoperation that a key that should be pressed only once is accidentally pressed continuously. In addition, when making a call using a mobile phone, it is usually difficult to grasp the operating state of the mobile phone immediately after the call because the user does not see the screen. Therefore, when the on-hook key is operated at the end of the call, the user has to intentionally look at the screen and be careful not to end the application programs other than the call function, which reduces the convenience. I'm worried.

An object of the present invention is to provide a mobile phone which is capable of avoiding the influence of an erroneous operation while ensuring the convenience of operation even when a plurality of functions are installed.

[0009]

In order to solve the above-mentioned problems, a mobile telephone which can execute a plurality of functions including a calling function and which has a storage means for storing the functions and a display means When an incoming call occurs while executing a function other than the above, the function being executed is detected, the function is temporarily stored in the storage means without terminating the function, and the operation other than the call operation is not accepted. When there is an incoming call control unit that shifts to the non-operation state and a function that shifts to the non-operation state by the incoming call control unit, it is confirmed that there is a function that shifts to the non-operation state by the display unit. A display control means for executing a display for informing, and a call for changing the function to the execution state when a call operation is performed for the function which has been changed to the non-operation state by the incoming call control means. It is characterized in that it comprises a stage, a.

The ROM 102 stores the basic control program of the mobile phone 1, various application programs, data related to these programs, and the like in the CPU 101.
Are stored in a readable form. ROM1
The programs and data stored in 02 are stored in the ROM in advance.
The configuration may be written in 102, or may be transmitted via a wireless communication line established between a base station (not shown) and the mobile phone 1.

The RAM 103 forms a work area for temporarily storing a basic control program executed by the CPU 101, various application programs, and data related to these programs.

The RF section 105 is connected to the antenna 8 and the baseband section 104, and has a built-in transmitting / receiving circuit for transmitting / receiving a voice signal and data in a predetermined frequency band via the antenna 8. Then, the RF unit 105

Next, the operation of the first embodiment will be described. FIG. 3 is a flowchart showing the operation of the mobile phone 1.

In the processing shown in FIG. 3, the CPU 101
First, the application program specified by the instruction input from the input unit 108 is read from the ROM 102 and executed (step S11).

When an incoming call to the mobile phone 1 occurs after the execution of this application program is started (step S12), the CPU 101 shifts the running application program to the icon state and displays it in the corner of the screen (step S12). S13).

Here, the icon state refers to a state in which a direct operation by the user is not performed. For example, CPU1
The e-mail editing program executed by 01 sequentially performs editing processing according to the user's operation, and always waits for the user's operation. Therefore, when converting the electronic mail editing program into an icon, the CPU 101
While holding the content of the mail being edited, hold the state of waiting for the user's operation.

Further, for example, a program for accessing a predetermined server via a wireless communication line established between a base station (not shown) and the mobile phone 1 and downloading a program or data is No user action is required unless a download is completed or an error occurs. Therefore, when the program is iconized, the CPU 101 continuously executes the program as a process in the background.

As described above, when the application program needs to be operated by the user when the application program is converted into an icon, the CPU 101 suspends the operation of the user in a standby state, and then operates the user. If you don't need, run it in the background. That is, in any case, the input unit 1 relating to the application program
The state shifts to a state where the input from 08 is not accepted.

Then, the CPU 101 uses the off-hook key 5
1 (Fig. 1) wait until the off-hook key 5
When 1 is operated (step S14; Yes), a wireless communication line is established between the mobile phone 1 and a base station (not shown), and a call process for making a voice call is performed (step S).
15). After starting the call processing, the CPU 101 waits until the on-hook key 52 (FIG. 1) is operated (step S16).

When the call ends and the user operates the on-hook key 52 (step S16; Yes),
The CPU 101 terminates the call and performs a call termination process for disconnecting the wireless communication line between the mobile phone 1 and the base station (not shown) (step S17).

Subsequently, the CPU 101 searches for an application program in an iconized state (step S18), and causes the display unit 107 to display a standby screen including an icon corresponding to the detected application program (step S19). ).

Here, when an operation for selecting and designating the icon being displayed is performed in the application operating unit 4 or the key input unit 5 (step S20; Yes), CP
U101 shifts the designated application program to the execution state (step S21). The execution state means a state in which the application program is being executed at the time of incoming, that is, a state in which an input from the input unit 108 regarding the application program is accepted.

The image of the icon displayed in the above process is stored in the ROM 102 in advance. Further, the application program stored in the ROM 102 is expanded on the RAM 103 and executed when the execution is instructed. Then, when an incoming call occurs during execution of the application program, an icon is associated with each running application program, and information associating the icon with the application program is stored in the RAM 103.

FIG. 4 is a diagram showing an example of a screen displayed on the display screen 3 (FIG. 1) in the processing shown in FIG.
(A) shows the mail edit screen 301, (b) shows the incoming screen 302, (c) shows the in-call screen 303,
(D) shows a standby screen 304, and (e) shows a mail editing screen 301.

When the e-mail editing program is executed on the mobile phone 1, the screen shown in FIG.
As shown in (a), the mail edit screen 301 is displayed.

When an incoming call is received by the mobile phone 1, the running e-mail editing program is converted into an icon, and an incoming call screen 302 is displayed on the screen of the display screen 3 as shown in FIG. 4 (b). To be done.

When the off-hook key 51 (FIG. 1) is operated to start a call, a talking screen 303 is displayed on the screen of the display screen 3 as shown in FIG. 4 (c).

After that, the on-hook key 52 (FIG. 1) is operated, and when the call ends, the screen of the display screen 3 shows
A standby screen 304 is displayed as shown in FIG.
Here, since the electronic mail editing program is iconized, an icon 305 corresponding to the electronic mail editing program is displayed on the standby screen 304.

When the icon 305 is selected and designated by the operation of the application operating unit 4 or the key input unit 5, the iconized electronic mail editing program shifts to the execution state and is displayed on the screen of the display screen 3. Is
A mail edit screen 301 is displayed as shown in FIG.

Therefore, since the standby screen 304 is displayed on the display screen 3 when the call ends, the operation is not switched even if the on-hook key 52 is pressed in this state. As a result, even if the on-hook key 52 is operated a plurality of times at the end of the call, the standby screen 304 is displayed, so that there is no fear that processing due to an erroneous operation will proceed and the operation of the mobile phone 1 will be comfortable. Can be

The iconified application program is the icon 3 displayed on the standby screen 304.
It can be easily executed by selecting and specifying 05. The iconified application program can be differentiated from the non-iconified program by the icon 305. This allows
Since the user can easily know what the program was executing before the call, the convenience of the mobile phone 1 can be further improved.

The description of the first embodiment is a preferred example of the mobile phone according to the present invention.
The present invention is not limited to this. For example, the example in which only one icon 305 is displayed as the standby screen 304 has been shown, but the present invention is not limited to this, and it is of course possible to display a plurality of icons.
It is also possible to call and execute other functions while the icon 305 is displayed.

Further, for example, in the present embodiment, the running application program is displayed as the icon 305 on the standby screen 304, but the present invention is not limited to this, and for example, a menu display function may be used. Less than,
This example will be described as a second embodiment.

[Second Embodiment] The second embodiment will be described with reference to FIGS. 5 and 6. In addition, in the second embodiment, the configuration of the mobile phone 1 is the same as that of the first embodiment, and illustration and description of the configuration are omitted.

FIG. 5 is a flowchart showing the operation of the mobile phone 1 according to the second embodiment to which the present invention is applied. In the process shown in FIG. 5, the CPU 101 first reads the application program designated by the instruction input from the input unit 108 from the ROM 102 and executes the application program (step S31).

When an incoming call to the mobile phone 1 occurs after the execution of this application program is started (step S32), the CPU 101 adds the application program being executed to the call menu list (step S33).

Here, the call menu list is a kind of menu list in which the application program being executed at the time of incoming call is registered. This call menu list is provided separately from the general menu list in the mobile phone capable of executing a plurality of applications, and is stored in the RAM 103. The application program added to the call menu list shifts to a state where the user does not directly operate. For example, the e-mail editing program executed by the CPU 101 sequentially performs editing processing according to the user's operation, and always waits for the user's operation. Therefore,
When the e-mail editing program is executed in step S31, the CPU 101 holds the contents of the mail being edited while holding the state waiting for the user's operation.

Further, for example, a program for accessing a predetermined server via a wireless communication line established between a base station (not shown) and the mobile phone 1 to download a program or data is No user action is required unless a download is completed or an error occurs. Therefore, when the program is executed in step S31, the CPU 101 continuously executes the program as a background process.

As described above, when the application program needs to be operated by the user when the application program is added to the call menu list, the CPU 101 suspends the operation by waiting for the user operation. If it does not require user operation, it is executed in the background. In other words, in any case, unless the icon is selected and designated or the operation of calling from the call menu list is performed, the input unit 10 relating to the application program
The state shifts to the state where the input from 8 is not accepted. It should be noted that in the mobile phone 1, the application program can be operated by selecting an icon or operating the call menu list even during a call, but the processing process thereof will not be described in detail here.

Then, the CPU 101 uses the off-hook key 5
1 (Fig. 1) wait until the off-hook key 5
When 1 is operated (step S34; Yes), a wireless communication line between the mobile phone 1 and a base station (not shown) is established, and a call process for making a voice call is performed (step S).
35).

When the call ends and the user operates the on-hook key 52 (step S36; Yes),
The CPU 101 terminates the call and performs a call termination process of disconnecting the wireless communication line between the mobile phone 1 and the base station (not shown) (step S37).

Subsequently, the CPU 101 causes the display unit 107 to display a standby screen (step S38), and shifts to a standby state for an operation by the user (step S3).
9).

Here, when an operation relating to the display of the calling menu list is performed in the application operating section 4 or the key input section 5 (step S39; Yes), C
The PU 101 causes the display unit 107 to display the call menu list (step S40). Then, when the operation of selectively designating the application program displayed in the call menu list is performed, the CPU 101 shifts the designated application program to the execution state (step S41). The execution state refers to a state in which the application program is being executed at the time of incoming call in step S31, that is, a state in which an input from the input unit 108 regarding the application program is received.

In the above processing, the ROM 102
When the execution instruction is given, the application program stored in the file is expanded on the RAM 103 and executed. Then, when an incoming call occurs during execution of the application program, a call menu list for each running application program is created, and the RAM 10
3 is stored.

FIG. 6 is a diagram showing an example of a screen displayed on the display screen 3 (FIG. 1) in the processing shown in FIG.
(A) shows the mail edit screen 311, (b) shows the incoming call screen 312, (c) shows the talking screen 313,
(D) shows a standby screen 314, (e) shows a menu screen 315, and (f) shows a call menu list display screen 3
16 and (f) shows a mail edit screen 311.

When the e-mail editing program is executed on the mobile phone 1, the screen shown in FIG.
As shown in (a), the mail edit screen 311 is displayed.

When an incoming call is received by the mobile phone 1, the running e-mail editing program is converted into an icon, and the incoming call screen 312 is displayed on the screen of the display screen 3 as shown in FIG. 6 (b). To be done.

When the off-hook key 51 (FIG. 1) is operated to start the call, the talking screen 313 is displayed on the screen of the display screen 3 as shown in FIG. 6 (c).

After that, when the on-hook key 52 (FIG. 1) is operated and the call ends, the screen on the display screen 3 shows
As shown in FIG. 6D, a standby screen 314 is displayed. A message icon 314a indicating that there is an application program added to the call menu list is displayed on the standby screen 314 shown in FIG. 6D. Therefore, when the user finishes the call, the standby screen 314 including the message icon 314a is displayed to notify the user that the application program whose operation has been interrupted is added to the call menu list.

When a menu list is displayed by operating the application operating unit 4 or the key input unit 5, a menu screen 315 is displayed on the screen of the display screen 3 as shown in FIG. 6 (e). Is displayed. The menu screen 315 is a screen in which items for setting the mobile phone 1 and selecting a tool are displayed as a menu. And
In the menu screen 315 shown in FIG. 6E, "3.
The item “application” is an item for displaying the call menu list. That is, in the example shown in FIG. 6E, the instruction operation for displaying the calling menu list is generally associated with a part of the menu function of the mobile phone 1. Note that the configuration of the menu screen shown in FIG. 6E is merely an example, and as an implementation mode of the present invention, an operation of displaying a call menu list is performed.
Of course, it is possible to separate it from the general menu function.

When the operation of selecting the item "3. Application" is further performed with the menu screen 315 displayed on the display screen 3, as shown in FIG.
A call menu list display screen 316 is displayed on the display screen 3. The call menu list display screen 316 displays RA
It is a screen which displays the content of the call menu list stored in M103. Then, when an application program is selected and designated on the call menu list display screen 316, the designated application program shifts to the execution state, and a mail edit screen 311 is displayed on the display screen 3 as shown in FIG. Is displayed.

It is also possible to use a standby screen 317 shown in FIG. 6 (h) instead of the standby screen 314 shown in FIG. 6 (d). A message display 317a indicating that there is an application program added to the call menu list is displayed on the standby screen 317. In this case, when the user finishes the call, the standby screen 317 is displayed, so that the message display 317a is displayed to the user.

Therefore, according to the mobile phone 1 in the second embodiment, the standby screen 314 is displayed on the display screen 3 at the time when the call ends, as in the first embodiment. Therefore, even if the on-hook key 52 is pressed in this state, the operation is not switched. As a result, even if the on-hook key 52 is operated a plurality of times at the end of the call, the standby screen 304 is displayed, so that there is no fear that processing due to an erroneous operation will proceed and the operation of the mobile phone 1 will be comfortable. Can be

If there is an application program whose operation is interrupted due to an incoming call to the mobile phone 1, a message icon 314 on the standby screen 314 is displayed.
With a, it is possible to notify the user that there is an application program that was being processed. This prevents the user from forgetting the application program that was being executed when the call arrived.

Further, the application program added to the menu list can be easily selected and specified while the menu list is displayed on the display screen 3 and easily executed. Thereby, the convenience of the mobile phone 1 can be further improved.

In the above embodiment, the icons displayed on the screen of the mobile phone 1, the message icon 314a, the message display 317a, etc. are displayed on the standby screen when the call is completed. However, the present invention is not limited to this, and may be displayed during a call. In this case, even during a call, it is possible to call the application program whose operation is interrupted and restart the operation.

Further, the arrangement and shape of each part of the display screen 3, the application operation part 4, the key input part 5, the speaker 6, the microphone 7, and the antenna 8 in the main body 2,
The specific detailed configuration is arbitrary. Further, it goes without saying that other specific configurations such as the configurations of the screens and designs shown in FIGS. 4 and 6 can be appropriately changed.
