Description

  The present invention relates to an information processing device such as a PDA or a tablet PC capable of communication including an audio packet with an external device via a network, and a program applied to these devices.

  In recent years, various portable information processing devices such as PDAs, tablet PCs, and notebook PCs have been developed. Many portable information processing devices of this type have a wireless communication function, and can be wirelessly connected to other information processing devices and various electronic devices via a network.

  When the conventional VoIP (voice over IP) software that realizes the IP phone function is installed and used on a computer such as a PC or PDA, the VoIP software is started as an application having a window, and the window is operated (tapped). It was possible to send / receive.

However, in the above-described prior art, since the window used as the operation screen is used in a constantly activated state, for example, when the device is carried and handled, the operation portion of the window (operation button or the like) is used. There has been a problem that a finger, an object, etc. may touch and cause a malfunction due to an incorrect operation. Further, at this time, there is a problem that reception by the VoIP application becomes impossible when the window serving as the operation screen is hidden and so-called screen lock is performed.

In this embodiment, the screen control driver 241 is under the control of the GUI module 231. The VoIP operation screen 10 is controlled to be displayed / hidden on the LCD 111.

  FIG. 3 shows a processing procedure according to the embodiment of the present invention, centering on the VoIP call control module 211 included in the VoIP control program 202 described above.

  FIG. 4 shows an example of the configuration of the VoIP operation screen 10 in the above embodiment. The VoIP operation screen 10 is displayed on the LCD 111 under the control of the screen control driver 241 and the display controller 104 as described above, and a display unit that displays incoming call contents, communication status, call status, etc. as a basic screen configuration. 11 and an operation unit that displays buttons to be tapped. In this embodiment, the display unit 11 displays the current time, caller information, communication, call status, and the like. The operation section blinks when an incoming call is received, and a “Call” button that is tapped when a call is made, a “hang up” button that is tapped when a call is disconnected, and a “Hold” that is tapped when a call is put on hold. Various operation buttons including a “Message” button that is tapped when transmitting a button or a message (text character) are provided.

Here, the operation in the embodiment of the present invention will be described with reference to the respective drawings.
When the VoIP call control module 211 of the VoIP control program 202 receives an incoming call notification from a communication partner device connected to the network via the wireless LAN device 109 and the communication library and detects an incoming call (steps S1 and S2 in FIG. 3), the screen The control driver 241 is accessed to acquire the display status information of the VoIP screen, and it is checked from the acquired status information whether the VoIP operation screen 10 is in a non-display state by the operation of the operation button 108 (FIG. 3). Steps S3 and S4).

  Here, when it is recognized that the VoIP operation screen 10 is in a non-display state by the operation of the operation button 108, the GUI module 231 is notified that the VoIP operation screen 10 is displayed, and an incoming call is received on the VoIP operation screen 10. A notification to display the contents is made (step S5 in FIG. 3).

  Upon receiving the above notification from the VoIP call control module 211, the GUI module 231 displays the VoIP operation screen 10 including the caller information on the LCD 111 of the display device 110 with reference to preset telephone directory data. (FIG. 3, step S11). At this time, the GUI module 231 displays the VoIP operation screen 10 in an operable state (as an active screen) in the forefront with priority over other application screens. Furthermore, the GUI module 231 flashes and displays a “Call” button provided on the operation unit of the operation screen 10 to notify the user that an incoming call has been received.

  In addition, the VoIP call control module 211 checks whether or not the VoIP operation screen 10 is in a non-display state by operating the operation button 108 (steps S3 and S4 in FIG. 3), and the VoIP operation screen 10 is already an active screen. When the display state is recognized, the process of notifying that the VoIP operation screen 10 is displayed (step S5 in FIG. 3) is omitted, and the GUI module 231 is notified that the contents of the incoming call are displayed. This is performed (step S5 in FIG. 3). As a result, the GUI module 231 flashes and displays a “Call” button provided on the operation unit of the operation screen 10 to notify the user that an incoming call has been received, and displays caller information on the display unit of the operation screen 10. 11 (step S11 in FIG. 3).

  When the user recognizes that there is an incoming call by the blinking display of the “Call” button, visually recognizes the display part of the VoIP operation screen 10, and taps the “Call” button on the operation screen 10, for example (FIG. 3). In step S12, S13), the button operation information is notified to the VoIP call control module 211 via the screen control driver 241 (steps S14, S15 in FIG. 3).

  When receiving the operation information of the “Call” button, the VoIP call control module 211 returns an incoming call response to the communication counterpart device connected to the network via the communication library and the wireless LAN device 109 (step S16 in FIG. 3). Thereafter, communication such as a telephone call and message exchange using the IP telephone function is possible with the communication partner device.

  In the embodiment described above, when the VoIP operation screen 10 is hidden by the operation of the operation button 108, if there is an incoming call from the other party, the VoIP operation screen 10 is displayed (redisplayed) immediately in response to the incoming call. It was. Although the display activation control of the operation screen 10 at the time of an incoming call is excellent in responsiveness, there remains a problem that an operation error may be caused after the operation screen 10 is activated. Therefore, when the VoIP operation screen 10 is not displayed by the operation of the operation button 108 and there is an incoming call from the other party, first, the VoIP operation screen 10 having only the display unit 11 as shown in FIG. The message is displayed on the LCD 111 to inform the user that there has been an incoming call and the caller, etc., and then, after a predetermined time (time lag) or a predetermined operation (for example, operation of the operation button 108), FIG. By displaying each button of the operation unit shown in FIG. 4 and enabling the operation of the VoIP operation screen 10, it is possible to further reduce operation errors including after the display activation of the operation screen 10.
