Description

  The present invention relates to a communication terminal having an application function such as a camera or a game, and more particularly to a communication terminal that preferentially executes an application function.

  Generally, in a wireless communication system used in a mobile phone terminal, communication is established by the mobile phone terminal intermittently repeating a reception operation with respect to a base station. The intermittent reception operation interval is usually a very short time of about 1 to 2 seconds in order to prepare for a call from a partner terminal that cannot be predicted when it occurs. Some mobile phone terminals have application functions such as cameras and games. The receiving operation and application function are controlled by the control means.

Conventionally, a mobile phone terminal always performs an intermittent reception operation even while an application function such as a camera or a game is operating. When it is determined that data has arrived, the radio data from the base station is received by the antenna, demodulated and channel-decoded, and then transferred to the control means as data that can be discriminated between voice data and packet data. It is. Further, when receiving the data, the mobile phone terminal generates an incoming call interrupt signal for the control means. When the control means confirms the incoming call interrupt signal, the control means performs temporary suspension processing of the application function and performs voice processing on the received data.

  However, in recent mobile phone terminals, the evolution of functions other than voice calls, which are the original functions of mobile phone terminals such as digital cameras and games, has been remarkable. Accordingly, the mobile phone terminal can be used as one digital camera or one game machine, and such a need has arisen. In addition, mobile phone terminals tend to place greater importance on sending and receiving e-mails as a means of communication than voice calls, and are especially seen in the younger generation.

  Furthermore, conventional mobile phone terminals tend to always give priority to voice calls because of their existence as devices. Accordingly, the mobile phone terminal has a problem in that a call is given priority even when an application function such as a camera or a game is being used, and the application function is temporarily interrupted.

  In addition, mobile phone terminals check whether there is always incoming data by intermittently receiving with the base station as a wireless communication system, but the effect of intermittent reception on the battery duration Is big. As a result, there is also a problem that time for using application functions such as a camera and a game is reduced.

  SUMMARY An advantage of some aspects of the invention is that it provides a communication terminal that prioritizes an application function over a call function and an application function control method for the communication terminal.

  The communication terminal of the present invention includes an interrupt control unit that detects a reception interrupt of received data, a received data determination unit that determines whether the received data is voice data or packet data, and the received data is a voice. An incoming call disabling notification means for notifying the calling side that an incoming call cannot be made when determined as data, and a packet data arrival notifying means for notifying the arrival of packet data when the received data is determined as packet data; , Is adopted.

  ADVANTAGE OF THE INVENTION According to this invention, the application function control method of the communication terminal and communication terminal which perform an application function preferentially over a telephone call function can be provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram illustrating an example of the configuration of the mobile phone terminal according to Embodiment 1 of the present invention, and FIG. 2 is a block diagram illustrating an example of the configuration of the control unit according to Embodiment 1. In this embodiment, a mobile phone terminal will be described as an example of a communication terminal.

  The cellular phone terminal 100 includes an antenna 110, an RF LSI (Radio Frequency Large Scale Integration) 120, an analog baseband LSI (ABB LSI) 130, a digital baseband LSI (DBB LSI: Digital Base Band Large Scale). Integration) 140, microphone 150, and speaker 160.

  The antenna 110 receives received data, and the RF LSI 120 is equipped with an antenna module for transmitting and receiving wireless data. Thereby, the exchange of data using the radio frequency band of communication between the base station and the mobile phone terminal 100 is realized. The ABB LSI 130 converts the data format between an analog format and a digital format.

  The digital baseband LSI 140 demodulates the received data and performs channel decoding processing, performs data processing according to the type of each data, and executes application functions provided in the mobile phone terminal 100.

  The microphone 150 inputs user's voice, and the speaker 160 outputs voice.

  The digital baseband LSI 140 includes a baseband processing unit 141, an application unit 142, an audio processing unit 143, a packet data processing unit 144, and a control unit 200. Each function included in the baseband processing unit 141 operates under the control of a CPU (Central Processing Unit). Note that the CPU is not explicitly shown in FIG.

  The baseband processing unit 141 demodulates the received data and performs channel decoding processing, notifies the processed data to the control unit 200, or notifies the reception of the received data.

  The application unit 142 is an application that executes functions such as a camera and a game included in the mobile phone terminal 100.

  The voice processing unit 143 performs processing for notifying the user of voice data.

  The packet data processing unit 144 performs processing for notifying the user of packet data. The packet data refers to data other than audio data among data handled by the mobile phone terminal 100. As an example of packet data, mail, music, moving images, photographs, and the like are assumed.

  As illustrated in FIG. 2, the control unit 200 processes the data transferred from the baseband processing unit 141. The control unit 200 includes an interrupt control unit 210, a mode selection unit 220, a mode storage unit 230, a reception data determination unit 240, an incoming call failure notification unit 250, a packet data incoming notification unit 260, a reception interval setting unit 270, and an intermittent reception operation unit 280. And a mail check unit 290.

  The interrupt control unit 210 receives an occurrence of an interrupt of received data from the baseband processing unit 141 and receives received data. Further, the reception data is transferred based on the reception mode and the type of the reception data. The reception mode is acquired by reading the reception mode stored in the mode storage unit 230. The type of received data is acquired from the received data determination unit 240. When the reception mode is the function mode, the interrupt control unit 210 instructs the execution of processing to either the incoming call impossible notification unit 250 or the packet data incoming notification unit 260. When the reception mode is the normal mode, the interrupt control unit 210 transmits voice data. Packet data is transferred to the packet data processing unit 144 to the voice processing unit 143.

  The mode selection unit 220 selects a reception mode for selecting the processing data priority. The reception mode is a normal mode that maintains a normal reception state and a function mode that prioritizes execution of application functions. The mode selection unit 220 receives the reception mode (normal mode or function mode) selected by the user and stores it in the mode storage unit 230.

  The mode storage unit 230 is a storage area that stores the reception mode selected by the mode selection unit 220.

  The reception data determination unit 240 determines the type of reception data and notifies the interrupt control unit 210 of the determined data type. For the data type, the received data determination unit 240 determines whether the received data is voice data or packet data. Header data is added to all data sent from the base station, and the data is compressed at the stage of reception by the RF LSI 120 and digital conversion by the ABB LSI 130. The digital baseband LSI 140 demodulates the compressed data and passes the demodulated data to the control unit 200. The received data discriminating unit 240 determines how to process the received data based on the header information. For example, voice codec processing is necessary when voice data is received, and concealment cancellation processing is required for packet data.

  When the voice data is received during the function mode, the incoming call impossible notification unit 250 notifies the calling communication terminal that the incoming call cannot be received.

  The packet data arrival notification unit 260 notifies the user that the packet data has been received when the packet data is received during the function mode. Specifically, the packet data arrival notification unit 260 notifies the arrival of packet data by blinking an LED (Light Emitting Diode) device or the like.

  The reception interval setting unit 270 sets a time interval for performing incoming call processing.

  The intermittent reception operation unit 280 performs reception processing for received data at the reception interval set by the reception interval setting unit 270.

  The mail check unit 290 confirms whether a new mail has arrived at the base station server.

  Next, the operation of the mobile phone terminal 100 having the above configuration will be described. A general reception operation is performed as follows.

  When there is an incoming data, the received data from the base station is received by the antenna 110, processed by the RF LSI 120 and the ABB LSI 130, and then delivered to the digital baseband LSI 140. In the digital baseband LSI 140, the baseband processing unit 141 demodulates the received data and performs channel decoding processing, and then delivers the data to the control unit 200 as data that can be determined as audio data or packet data. In addition, the baseband processing unit 141 causes the control unit 200 to generate an incoming call interrupt signal. When the control unit 200 confirms the incoming call interrupt signal notified from the baseband processing unit 141, the control unit 200 processes the received data. In the normal mode, when the received data is confirmed, the control unit 200 performs an application function temporary suspension process on the application unit 142 to activate the audio processing unit 143, and the audio processing unit 143 performs audio processing.

  Next, the operation in the function mode will be described using the flowchart shown in FIG. FIG. 3 is a flowchart showing an example of the operation when the function mode is selected in the mobile phone terminal according to the present embodiment.

  The reception mode and the reception interval are input in advance by the user. At this time, the mobile phone terminal 100 performs the following operation. The mode selection unit 220 stores the function mode selected by the user in the mode storage unit 230. In addition, the reception interval setting unit 270 notifies the reception interval input by the user to the intermittent reception operation unit 280. After such setting, the mobile phone terminal performs the following operation.

  First, the intermittent reception operation unit 280 performs a reception operation on the base station at every reception interval (S11). When the intermittent reception operation is started, the application function is executed in parallel with the reception operation.

  When it is determined that the reception data from the base station has been received by the interrupt control unit 210 (YES in S12), the interrupt control unit 210 delivers the received data to the reception data determination unit 240. The interrupt control unit 210 notifies the intermittent reception operation unit 280 that reception data has been received.

  On the other hand, when there is no reception data from the base station in the interrupt control unit 210 (NO in S12), the processing after S16 is performed. The intermittent reception operation unit 280 determines that there is no reception data when there is no notification from the interrupt control unit 210 for a predetermined time.

  Next, in order to determine the received data type, the received data determination unit 240 determines whether the received data is voice data or packet data, and notifies the interrupt control unit 210 of the determined data type. When the received data is voice data (YES in S13), the interrupt control unit 210 notifies the incoming call failure notification unit 250 that the voice data has been received. The unacceptable notification unit 250 notifies the caller that the incoming call cannot be made (S14). When the received data is packet data (NO in S13), the received data determination unit 240 notifies the packet data incoming notification unit 260 that the packet data has been received. The packet data arrival notification unit 260 controls blinking of the LED device and the like, notifies the user of the arrival of packet data, and cancels the incoming interrupt from the baseband processing unit 141 to the interrupt control unit 210 (S15).

  Next, the intermittent reception operation unit 280 activates the mail check unit 290. The mail check unit 290 confirms whether a new mail has arrived at the base station server (S16). When the mail check unit 290 confirms the arrival of a new mail to the base station server (YES in S17), the mail check unit 290 notifies the packet data incoming notification unit 260 of the incoming new mail. The packet data incoming notification unit 260 controls blinking of the LED device and notifies the user of incoming packet data (S18).

  After NO in S17 or after completion of the processing in S18, the application unit 142 executes only the application function until the next intermittent reception operation is started (S19).

  As described above, in a mobile phone having an application function such as a camera or a game, the function of receiving data can be maintained at a minimum while the application function is being executed. Specifically, when an incoming voice data is received, priority is given to the execution of the application function. On the other hand, when there is an incoming packet data while executing the application function, only the incoming notification of the packet data can be performed by blinking the LED device or the like. Therefore, even when incoming data is received during execution of the application function, the application function is not substantially interrupted. Furthermore, it is possible to extend the usage time of the application function by reducing the power due to the communication operation.

  Also, the reception interval setting unit 270 can set the interval of the intermittent reception operation longer than that in the normal mode.

  Furthermore, by always performing an incoming mail inquiry process on the base station server after the receiving operation with the base station, it is possible to prevent the packet data not received from the base station server from being left unattended. In the present embodiment, in the function mode in which the application function is prioritized, the intermittent control interval becomes long, so that it is not possible to expect much mail reception by the intermittent reception control unless the incoming mail is accidentally picked up during the reception operation. The reason why the intermittent reception interval is set longer than before is to reduce the battery consumption due to frequent intermittent reception operations and to secure the battery time for executing the application function (the communication itself by voice call is also Not accepted). As a result, although the real-time property of communication is impaired, it is possible to ensure communication by mail without the need for real-time property by automatically performing mail incoming inquiry processing after intermittent reception operation.

  In this embodiment, the application function and the intermittent reception operation are executed in parallel. However, the application function can be temporarily interrupted during the intermittent reception operation. When the function mode is set, since the time required for the intermittent reception operation is very short, it does not affect the execution of the application function for the user.

  Further, in the present embodiment, the case where the interrupt control unit 210 notifies the reception failure notification unit 250 or the packet data arrival notification unit 260 of the reception of the reception data has been described. However, instead of the interrupt control unit 210, the reception data determination unit 240 may do.

  In the present embodiment, a mobile phone terminal has been described as an example of a communication terminal. However, the present invention is not limited to this. Even if it is other than a mobile phone terminal, the present invention can be applied to any communication terminal that has a communication function and an application function. In the above description, the case of a communication terminal using a wireless communication system has been described, but the present invention can also be applied to a communication terminal using a wired communication system.

  Furthermore, in the present embodiment, an example in which new mail is checked by the mail check unit 290 has been described. However, not only new mail but also packet data received at the base station server may be checked.

(Embodiment 2)
In Embodiment 2, a case will be described in which reception interval setting section 270 shown in FIG. 2 holds a plurality of reception intervals in advance and allows the user to select from a plurality of reception intervals.

  The reception interval setting unit 270 displays a plurality of reception intervals on the display screen. The intermittent reception operation unit 280 is notified of the reception interval selected by the user.

  New mail stored in the base station server is checked by the mail check unit 290 at each reception interval. For this reason, the user who attaches importance to the mail function can change to a communication terminal that prioritizes the application function. In addition, the communication terminal can increase the proportion of power used for the application function.

(Embodiment 3)
The configuration of the control unit 200 shown in FIG. 2 can be executed by hardware, software, or a combination of hardware and software. The control unit 200 can be realized by a control program executed by a computer.

  The control program includes steps (means, procedures) for executing the following functions.

  First, as a function for realizing the function mode, the following steps are required. The function for realizing the function mode includes an interrupt control step for detecting a reception interrupt of reception data, a reception data determination step for determining whether the reception data is voice data or packet data, and the reception data is An incoming call disapproval notification step for notifying that incoming data cannot be received when it is determined as voice data; and a packet data incoming notification step for notifying the arrival of packet data when the received data is determined as packet data. .

  Furthermore, the function for realizing the function mode includes a mode selection step of selecting either a reception mode that prioritizes processing of received data or a function mode that prioritizes an application function of the communication terminal, and the incoming call failure notification step Notifies the caller that the incoming call cannot be made when the received data is voice data and the function mode is set by the mode selection step. As a result, the function mode and the normal mode can be selected, and the communication terminal desired by the user can be easily changed.

  The communication terminal includes a reception interval setting step for setting a reception interval for repeating the reception operation, and an intermittent reception operation step for repeating the reception operation using the reception interval. As a result, the reception interval can be set, so that the communication function desired by the user can be flexibly selected. For example, even when the normal mode is selected, it is possible to select to increase the interval between reception operations.

  In this way, even if a mobile phone with an application function such as a camera or a game receives data from the base station while the application function is operating with the minimum necessary communication means by mail notification being secured. A running application function is not interrupted. In addition, the usage time of the application function can be extended by reducing the power generated by the communication operation.

  The communication terminal and the application function control method of the communication terminal according to the present invention are useful in meeting the needs for users who emphasize application functions in recent mobile phone terminals in which application functions such as cameras and games have evolved.
