The configuration of the wireless access point 5 is the same as that of the cellular base station 2 described above.

  FIG. 5 is a block diagram illustrating a configuration example of a main part of the mobile phone 10 of FIG. In the cellular phone 10, the microprocessor 100 includes an IP call control unit 121, an incoming call notification control unit 122, and a cellular call control unit 123. The incoming call notification control unit 122 and the cellular call control unit 123 are functions provided by executing a cellular phone program.

  The IP call control unit 121 controls the IP communication unit 102 to perform an IP call via the wireless access point 5 based on an operation signal from the operation unit 103. In IP communication, voice data consisting of transmitted sound is compressed, broken down into a number of packets and transmitted to the other party, while packets received from the other party are assembled and expanded in time series, and voice data consisting of received voice Provided by playing.

  When the cellular communication unit 101 receives an incoming signal, the incoming notification control unit 122 performs incoming notification based on the incoming signal. The incoming call notification is performed by outputting a ring tone from the speaker 16, displaying a message notifying the incoming call on the display unit 13, or vibrating the vibrator 104. The ring tone can be output from the speaker 16 by generating a notification audio signal and outputting it to the audio codec 110. The volume and tone color of the ringtone are determined in advance. The incoming call notification is continuously performed until the call state is changed or the communication line is disconnected.

  Based on the operation signal from the operation unit 103, the cellular call control unit 123 controls the cellular communication unit 101 to perform a cellular call via the cellular base station 2. A cellular call is provided by compressing an audio signal composed of a transmitted sound and transmitting it to the other party, while reproducing an audio signal composed of the received sound by expanding the audio signal received from the other party.

  The cellular call control unit 123 starts a cellular call based on an off-hook operation during incoming call notification. Further, the cellular call control unit 123 ends the cellular call if an on-hook operation is performed or the communication line is disconnected.

  The IP call control unit 121 ends the IP call based on an off-hook operation during incoming call notification. That is, even if there is an incoming call for a cellular call, the IP call is not terminated, and the IP call is forcibly terminated when the communication state of the cellular call shifts to the call state. By configuring in this way, it is possible to prevent the IP call from being forcibly terminated against the user's intention.

  The incoming call notification control unit 122 performs different incoming call notifications based on whether or not an IP call is in progress when an incoming call signal is received. For example, if the incoming call notification control unit 122 receives an incoming call signal when the IP call is not in progress, the incoming call notification control unit 122 performs incoming call notification through the speaker 16. In this case, a ring tone is output from the speaker 16.

  On the other hand, if the incoming call notification control unit 122 receives an incoming call signal during an IP call, the incoming call notification is performed by the receiver 12. In this case, a predetermined notification sound is output from the receiver 12. The notification sound is superimposed on the received sound. By comprising in this way, it can suppress that a user is surprised by the alerting | reporting alert | report during IP telephone call.

  Here, the incoming call notification control unit 122 determines whether or not an IP call is in progress based on the operating states of the receiver 12 and the microphone 15 and the amount of communication data with the wireless access point 5. Specifically, if a state where all of the following four conditions (1) to (4) are satisfied continues for a certain time or more, it is determined that the IP call is in progress.

  Condition (1) is that the sound path including the receiver 12 and the microphone 15 is on. Condition (2) is that a certain amount of packets are transmitted when a voice signal is input. In condition (3), an audio signal is output when a certain amount of packets are received. In condition (4), one application program executes conditions (1) to (3). When there are a plurality of IP telephone programs, the application program is specified based on the conditions (1) to (4).

  With this configuration, the cellular call control unit 123 can detect whether or not an IP call is in progress without providing a control interface in the IP call control unit 121.

  In addition, the cellular call control unit 123 notifies the dummy information indicating the non-incoming state in response to the state notification request from the IP call control unit 121 during the incoming call notification. This dummy information is fake information for preventing the IP call control unit 121 from detecting that it is in an incoming state. The IP call control unit 121 periodically outputs a status notification request to the cellular call control unit 123 during the IP call. If the communication state of the cellular call is either an incoming call state or a call state, the IP call control unit 121 Force exit. With this configuration, it is possible to prevent the IP call from being forcibly terminated due to an incoming call for a cellular call without changing the specifications of the IP phone program.

  Further, the cellular call control unit 123 does not perform an automatic response operation for automatically starting a cellular call during an IP call. The automatic answering includes a response process using the simple answering machine function, a response process using the drive mode function, and a response process using the incoming call rejection function.

  The simple answering machine function is a function of automatically answering, recording voice guidance indicating that it is an answering machine, and then recording the received sound. The drive mode function is a function that automatically responds and transmits voice guidance indicating that the vehicle is being driven, and then shifts to a call state.

  The incoming call rejection function automatically answers and sends a voice message to reject the incoming call when the caller's phone number matches a previously registered phone number to be rejected, and then disconnects the communication line. It is a function. During an IP call, these automatic response functions are temporarily disabled. In particular, during an IP call, the cellular call control unit 123 immediately disconnects the communication line without responding if an incoming signal is received from a caller designated to reject incoming calls. By configuring in this way, it is possible to prevent the IP call from being forcibly terminated against the user's intention.

  Steps S101 to S112 in FIG. 6 are flowcharts showing an example of the operation of the cellular telephone program in the mobile phone 10 in FIG. First, if there is an incoming call for a cellular call, the incoming call notification control unit 122 determines whether or not an IP call is in progress (steps S101 and S102).

  At this time, if there is an IP call, the incoming call notification control unit 122 performs incoming call notification by the receiver 12 (steps S103 and S104). On the other hand, if there is no IP call, the incoming call notification control unit 122 performs incoming call notification through the speaker 16 (steps S103 and S110).

  Next, if an off-hook operation is detected, the cellular call control unit 123 ends the incoming call notification and starts the cellular call, and ends this process (steps S105 and S111). Next, when the off-hook operation is not detected and the incoming call rejection function is set, the cellular call control unit 123 checks the caller's telephone number with the telephone number registered as an incoming call rejection target, and If the telephone numbers match, the communication line is immediately disconnected (steps S106 and S112).

  Next, when the off-hook operation is not detected and the incoming call rejection function is not set, the cellular call control unit 123 terminates the IP call and performs other automatic answering functions, that is, a simple answering machine function or If any of the drive mode functions is set, an automatic response is sent and a predetermined voice guidance is transmitted, and this process is terminated (steps S107 to S109).

  Until the IP call is terminated, the processing procedure after step S105 is repeated. Further, even if the IP call is terminated, if either the simple answering machine function or the drive mode function is not set, the processing procedure after step S105 is repeated.

  Steps S201 to S206 in FIG. 7 are flowcharts showing an example of the operation of the IP telephone program in the mobile phone 10 in FIG. First, if an off-hook operation for starting an IP call is detected, the IP call control unit 121 starts an IP call (steps S201 and S202), and requests a status notification from the cellular call control unit 123 ( Step S203).

  Next, if the communication state of the cellular call is either an incoming call state or a call state, the IP call control unit 121 performs a call end process for ending the IP call and ends this process (step S204). , S206). On the other hand, if the communication state of the cellular call is a non-incoming state, the IP call control unit 121 repeats the processing procedure after step S203 until an on-hook operation for ending the IP call is detected (step S205).

  Since the mobile phone 10 according to the present embodiment performs different incoming call notification based on whether or not an IP call is in progress when receiving an incoming call signal, it is possible to suppress surprise of the user by the incoming call notification during the IP call. it can. In addition, since the mobile phone 10 ends the IP call based on the off-hook operation during the incoming call notification, it is possible to prevent the IP call from being forcibly ended against the user's intention.

  In the present embodiment, when an incoming call signal for a cellular call is received, an incoming call notification is made by the speaker 16 if the IP call is not in progress, and an incoming call notification is made by the receiver 12 if the IP call is being made. However, the present invention does not limit the method of performing different incoming call notifications based on whether or not an IP call is in progress. For example, the configuration may be such that the volume or tone of the ringtone varies depending on whether or not the IP call is in progress. More specifically, if the IP call is in progress, the ring tone is output from the speaker 16 by lowering the volume than when the IP call is not in progress.

  In the present embodiment, an example has been described in which it is determined whether or not an IP call is in progress based on the operating states of the receiver 12 and the microphone 15 and the amount of communication data with the wireless access point 5. The present invention does not limit the method for detecting whether or not an IP call is in progress. For example, the IP call control unit 121 registers information indicating whether an IP call is in progress in a predetermined file or memory area. The cellular call control unit 123 determines whether or not the IP call is in progress by referring to the registration information. Even with such a configuration, the cellular call control unit 123 can detect whether or not an IP call is in progress without providing a control interface in the IP call control unit 121.
