FIG. 3 is a diagram for explaining the address book AD.
The address book AD stores and manages the address book data for each destination, and each record includes, for example, “address”, “face image” in addition to “name”, “phone number”, and “TV compatible flag”. , “Mail address” and other items. Here, the address book data such as “name”, “telephone number”, “address”, “face image”, etc. is based on data input from the key operation unit 24, data supplied from the recording medium 13 or the like. Although it is arbitrarily set, the “TV-compatible flag” is automatically set according to the presence / absence of connection with the other party every time a call is made with a TV phone.

  The “TV compatible flag” indicates whether or not the other party's device (mobile phone device 1, PC 4, fixed telephone 5) is a TV phone compatible model, whether or not a call on the TV phone is rejected, etc. This is information indicating whether or not the other party can use the videophone. If the other party supports the videophone, it is set (ON). If the other party does not support the videophone, it is reset (OFF). ) It should be noted that although the “TV correspondence flag” is all reset at the time of initial setting, the desired “TV correspondence flag” of the other party may be set by manual operation.

  Next, the operation concept of the cellular phone device 1 in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment. FIG. 4 is a flowchart showing an outline of the operation of the characteristic part of the present embodiment in the overall operation of the mobile phone device. When the flow of FIG. Return to).

FIG. 4 is a flowchart showing a telephone call process started to be executed in response to the operation of the TV phone button 24A.
First, after a telephone number of a call destination is selected and specified from the address book AD or directly inputted from the key operation unit 24 (step A1), a call operation (off-hook operation) by a video phone is performed (step H1). A2) The CPU 11 directly inputs from the key operation unit 24 whether the same phone number as that of the other party is included in the address book AD, that is, whether the other party's phone number has been selected from the address book AD. It is checked whether it has been done (step A3).

 If the destination telephone number is not registered in the address book AD, that is, if the destination telephone number is directly input from the key operation unit 24 (NO in step A3), the destination telephone number is addressed. Then, a calling operation by a TV phone is performed (step A4). As a result, it is checked whether or not the other party is connected (step A5), and if there is no incoming call response from the other party, that is, when connection failure is detected, the flow of FIG. However, when the connection with the other party is established (YES in step A5), the telephone call is started (step A6).

 When the line is cut off during the videophone call and the call is ended, the process proceeds to the next step A7, where a confirmation message for inquiring whether or not to register the current caller in the address book AD is displayed. Here, when the registration to the address book AD is instructed by the user operation (step A8), the process proceeds to the execution of the address book registration process (steps A9 to A11). That is, when the name of the other party is key-inputted (step A9) and the telephone number is input (step A9), the CPU 11 stores an address book record including the “name” and “phone number”. After being generated and newly registered in the address book AD (step A10), the “TV correspondence flag” in the new record is set (ON) to indicate that the other party is compatible with the TV phone. (Step A11).

 On the other hand, when the telephone number of the call destination is selected and specified from the address book AD (YES in step A3), the presence / absence of the set (ON / OFF) is referred to with reference to the "TV correspondence flag" of the other party Is checked (step A12), and if the "TV compatible flag" is set, a TV phone call operation is performed to this telephone number (step A13). As a result, it is checked whether or not the other party is connected (step A14). When the connection with the other party is established, the other party can also support the TV phone. The flag is set (step A15). In this case, the “TV compatible flag” has already been set. Then, the process proceeds to step A16, and after the telephone call is started, the call is kept until the line is cut off and the call is terminated.

 In addition, even if the “TV compatible flag” is set and the other party is registered as TV compatible (YES in step A12), there is no incoming response from the other party as a result of making a TV phone call to the other party. In other words, if a connection failure is detected (NO in step A14), there is a possibility that the other party has been changed to a non-compatible model that does not support the TV phone, so the “TV compatible flag” is reset. (OFF) (step A17). Then, a TV phone incompatibility confirmation message indicating that the video phone is incompatible is displayed and output (step A18). This non-confirmation confirmation message screen also includes a message for inquiring whether or not to change from a videophone to a voice call.

 Now, it is checked whether or not a voice call instruction for changing from a TV phone to a voice call is received (step A19). If there is no voice call instruction (NO in step A19), the flow of FIG. 4 (phone call processing) However, when an instruction to change the outgoing call by voice telephone is given (YES in step A19), a voice telephone call operation is performed to the destination telephone number (step A20). Then, after a voice call is started in response to establishment of a connection with the other party (step A21), the call state is kept until the line is cut off and the call is terminated.

 On the other hand, if the “TV flag” is reset when the TV phone button 24A is operated, and the other party is registered as non-TV compatible (NO in step A12), the outgoing call operation by the TV phone is temporarily suspended and In order to notify the fact, a non-confirmation confirmation message indicating that the other party is not compatible with the videophone is displayed and output (step A22). In this case, since there is a possibility that the other party has been changed to, for example, a TV phone compatible model, this message screen also includes a message for inquiring whether or not to try to make a TV phone call.

 Now, when an instruction to make a videophone call is given by a user operation (YES in step A23), the process proceeds to step A13 described above to make a videophone call. In this case, when the connection with the other party is established (YES in step A14), the "TV flag" is set and switched from "OFF" to "ON" (step A15), and then a telephone call is made. Start (step A16). In other words, even when the other party is registered as non-TV compatible, when a TV phone call is received at the other party as a result of making a videophone call to the other party, the “TV compatible flag” is set to make the TV compatible. The contents are changed.

  Further, in the state where the call operation by the TV phone is temporarily suspended and the TV phone non-confirmation confirmation message is being displayed and output, if an attempt to make a call by the TV phone is not instructed (NO in step A23), the process proceeds to step A19 described above. It is checked whether a telephone switching instruction has been received, that is, whether a voice telephone change instruction has been received. Here, in response to the telephone change instruction (YES in step A19), the CPU 11 performs an outgoing call operation by voice telephone to the destination telephone number (step A20).

  As described above, in the first embodiment, in addition to the “name” and “telephone number” for each destination, the “TV correspondence flag” indicating whether or not the videophone is supported is stored in the address book AD. In the managed state, the CPU 11 refers to the “TV correspondence flag” corresponding to the other party when a call by the TV telephone is instructed, and determines whether or not the other party is compatible with the video telephone. If it is determined that it is compatible with the videophone, the telephone communication unit 15 makes a videophone call. If it is not compatible with the videophone, the videophone call is suspended and a videophone incompatibility confirmation message is displayed. Since the display is output from the main display unit 20, it is possible to confirm in advance that the other party is not compatible with the videophone even if the other party is not aware of whether the videophone is supported. , TV It is possible to prevent wasteful transmission by.

  If the other party's “TV compatible flag” is set when the videophone call is made, but the other party cannot be connected, for example, a videophone non-confirmation confirmation message indicating that the other party is not compatible with the videophone is displayed. After receiving the display output, when a telephone switching instruction is received, the TV telephone is switched to a voice telephone call, so that the other party's telephone number can be switched to the TV without reselecting or re-entering. It is possible to switch from telephone to voice telephone. Also, when the other party's "TV compatible flag" is set when making a videophone call, the "TV compatible flag" is switched from "ON" to "OFF". Thus, for example, it is possible to change the “TV compatible flag” according to circumstances such as temporarily refusing a telephone call.

  Also, when the other party's “TV compatible flag” is reset when making a videophone call, the videophone call origination operation is temporarily suspended, and a TVphone non-confirmation confirmation message is displayed and output. When a call is received, as a result of trying to make a videophone call, if it is connected to the other party, the videophone call is started. Therefore, it is possible to deal with a model change on the other party. In this case, since the other party's "TV compatible flag" is switched from "OFF" to "ON", the "TV compatible flag" is changed to the actual condition of the other party (for example, whether the TV phone compatible model has been changed or not). It becomes possible to change according to.

When a call switching instruction is received in a state in which a videophone call non-compliance confirmation message is displayed and output while a videophone call operation is temporarily suspended, a voice call call is started. It is possible to switch from a TV phone to a voice phone without reselecting or re-entering the phone number.
If the other party of the videophone call is not registered in the address book AD, the telephone number is newly registered in the address book AD corresponding to the current party and the “TV flag” is set. Since “ON” is set, it is possible to automatically register the “TV correspondence flag” as a part of the address book data.

In the above-described first embodiment, the outgoing call on the videophone is suspended and the videophone incompatibility confirmation message is guided and displayed. However, the voice message may be used for guidance. At this time, a message prompting switching from the TV phone to the voice phone may be guided together.
(Example 2)

The second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, when an outgoing call by TV phone is instructed, if the other party supports the TV phone, the phone communication unit 15 makes a phone call by the TV phone, and the TV phone However, in this second embodiment, an arbitrary destination registered in the address book AD is selected and designated. At this time, with reference to the “TV flag” corresponding to the other party, it is determined whether or not it is compatible with the TV phone and the determination result is notified.

Is done.

 Here, it is checked whether the center key (TV phone call button / voice phone call button) arranged in the lower center portion of the partner information screen or the off-hook key on the key operation unit 24 has been operated (step B7, B13). If another operation is performed (NO in step B7 or NO in B13), address book data editing processing or the like is executed as a process corresponding to the operation (step B11). When the other party information screen is displayed and output, if the TV phone call button or the off-hook key is operated (YES in step B7), a call operation by the TV phone is performed to the destination phone number. (Step B8) After starting a videophone call in response to the establishment of a connection with the other party, the call state is maintained until an off-hook operation is performed and the call ends (steps B9 and B10).

 In addition, when a voice telephone call button or an off-hook key is operated in a state where the other party information screen not compatible with the videophone is displayed and output (YES in step B13), a voice telephone call is made to the destination telephone number. After a call operation is performed (step B14) and a voice call is started in response to establishing a connection with the other party, an off-hook operation is performed and the call is kept until the call ends (steps B15 and B16).

  As described above, in the second embodiment, when an arbitrary destination registered in the address book AD is selected and designated, the “TV correspondence flag” corresponding to this destination is referred to and the TV phone is called. And if it is “ON”, a videophone compatible icon is arranged and displayed on the partner information screen to determine whether the partner is also compatible with the videophone. Even if the user himself / herself is not conscious, the presence / absence of the TV phone can be confirmed in advance, and useless transmission by the TV phone can be prevented.

 Here, when the other party supports the videophone, a videophone call button is arranged and displayed on the other party information screen, and a videophone call is made according to the operation of the videophone call button.
