CPU 37, ROM 38, and RAM 39.

  In the mobile phone shown in FIG. 2, the base station wireless I / F means 31 is an I / F that performs wireless communication between the mobile phone and the base station. The LAN wireless I / F means 32 is an I / F that performs wireless communication between the mobile phone and the LAN wireless base station. Conventionally, a dedicated protocol is used for the base station wireless I / F means, but there are increasing cases of using the Internet network or the IP network between the base station side and the communication apparatus using the protocol. Furthermore, since the LAN protocol is originally communicated by IP, the base station wireless I / F means can be made IP to share parts and reduce costs. Therefore, as in this embodiment, the base station wireless I / F means 31 and the LAN wireless I / F means 32 use IP.

  There are two types of IP means 33: VOIP means used for voice and data IP means used for data communication.

  The VOIP means used for voice converts an analog voice signal sent from the call circuit into digital data, and if necessary, encodes and compresses it. Next, the audio signal data is embedded in the IP packet for transmission, and sequentially sent out to the base station wireless I / F means 31 or the LAN wireless I / F means 32. Also, the audio signal data is extracted from the receiving IP packet input from the base station wireless I / F means 31 or the LAN wireless I / F means 32, and is decoded and expanded if necessary, and the digital audio signal data is further extracted. It is converted into an analog voice signal and sent to the call circuit.

  In the case of the data IP means used for data communication, instead of the call circuit of the VOIP means, for example, input / output with a memory means may be performed, or a dedicated data processing means may be provided. The IP means 33 assembles control IP packets for performing call control, and sequentially sends them out to the base station wireless I / F means 31 or the LAN wireless I / F means 32. Further, the control IP packet received from the base station wireless I / F unit 31 or the LAN wireless I / F unit 33 is disassembled for analysis. Such transmission and reception of the control IP packet may be performed by another means independent of the IP means 33. The operation control of the IP unit 33 may be performed by the CPU 37 or a dedicated LSI may be used.

Since the call circuit 341, the microphone 342, the speaker 343, the GPS means 35, the operation input / display unit 36, the CPU 37, the ROM 38, and the RAM 39 are understood in accordance with FIG.

It is possible to enjoy various services such as using the information and charging the selected terminal identification information.
(SIP)
FIG. 7 shows a protocol of a SIP (Session Initiation Protocol) communication model which is one of standard call control protocols. First, a request message “INVITE” is sent from the calling side (S71). “INVITE” is a session activation signal, and an attribute of the session that can be received by the caller is indicated by SDP (Session Description Protocol). Specifically, the reception condition (codec, port number, etc.) and transmission condition on the calling side are presented. The called side receives “INVITE” and transmits “180 RINGING” to the calling side in order to notify that it is in the calling state (S72). The “180 RINGING” may indicate the receiving condition (codec, port number, etc.) and the transmission condition on the called side, but it is normally indicated by the following “200 OK”. Next, “200 OK” is transmitted to the calling side to notify that the called side is ready to talk (S73). For this, the attributes of the session that can be received by the called party are shown in SDP. This “200 OK” presents the receiving condition (codec, port number, etc.) and transmission condition on the called side. Next, the calling side transmits “ACK” to the called side (S74), and thereby the attributes that can be used for communication are negotiated. In the present invention, this is defined as the connection phase for convenience. Next, transfer of media (sound, image, video, etc.) is started (S75). In the present invention, this data transfer period is defined as a data transmission / reception phase for convenience. When terminating the communication, the stop side sends a “BYE” signal to request the end of the communication (S76), and the side receiving it transmits a “200 OK” signal as a response to terminate the communication ( S77). In the present invention, this phase is defined as a cutting phase for convenience.
(Example)
In the following description of embodiments of the present invention, a mobile phone (main body) will be described as an electronic device, and a W-USB (wireless USB) will be described as an example of a communication I / F. However, the present invention is not limited to other electronic devices. Needless to say, it can be applied to communication I / F.

  USB includes, for example, a host I / F provided in a PC (personal computer) and a device I / F provided in its peripheral devices. The host I / F and the device I / F described in the embodiments are almost the same. In brief, the host I / F is an I / F that is held by the party in charge of communication, and the device I / F. Is operated by a command on the host I / F side, and is similar to conventional command (response) / response (response) type communication.

  FIG. 8 shows a configuration example of a mobile phone which is an embodiment of the present invention. FIG. 8 includes a mobile phone 50 and an external operation unit (data input means) 59. Here, an external operation unit (external operation unit) will be described as an example of the peripheral device.

  The cellular phone 50 includes a display device 51, a main body operation unit (data input unit) 52, an input switching unit 53, an FEP (Japanese language conversion function) 54, an application 55, a host I / F 56, a detection unit 57, and a memory 58. ing.

  The external operation unit 59 includes a device I / F 591 and is connected to the host I / F 56 of the mobile phone 50 through a W-USB (Universal Serial Bus) interface.

  The display device 51 displays key information input from the operation unit and character information converted by the FEP. The main body operation unit (data input means) 52 is an operation unit provided in the main body for inputting characters, and is, for example, a numeric keypad. The input switching unit 53 switches between the data from the main body operation unit (data input unit) 52 and the data from the external operation unit 59 and outputs the data. The FEP 54 converts the key information transmitted from the input switching means into characters (particularly kanji or hiragana). The application 55 is an application that the mobile phone 50 has, and is mail software, mailer, mail editor, word processor software, editor, or the like. The host I / F 56 controls the device I / F 591 of the external operation unit 59 to perform communication between the mobile phone 50 and the external operation unit 59. The detecting unit 57 detects whether or not the external operation unit 59 is connected to the mobile phone 50 based on a signal from the host I / F. When the detection unit 57 detects that the external operation unit 59 is connected to the mobile phone 50, the input switching unit 53 switches to output data from the external operation unit 59, and the detection unit 57 When it is detected that the external operation unit 59 is not connected to the mobile phone 50, the input switching unit 53 switches to output data from the main body operation unit 52.

  Note that the input switching unit 53 may be included in the FEP 54. Further, the input switching unit 53 may switch the input from the main body operation unit 52 and the input from the external operation unit 59, or may transmit both inputs to the FEP 54 as they are.

  The external operation unit 59 is an external operation unit and is preferably a full keyboard.

  FIG. 9 shows a software stack according to an embodiment of the present invention.

  The lowermost layer includes a main body operation unit 63, an external operation unit 65, and a W-USB 64. The upper layer includes an input switching unit 62, an FEP 61, and an application 60. Information input from the main body operation unit 63 and the external operation unit 65 is sequentially transmitted to an upper layer and finally received by the application 60.

  Next, a processing flow will be described for a case where the external operation unit and the mobile phone are not connected and a case where the external operation unit and the mobile phone are connected.

(1) When External Operation Unit and Cellular Phone are not Connected A case where the mail software in this case is activated will be described with reference to FIG. First, e.g. mail software is activated on the portable electronic main body (S101). Character input is performed by pressing a key of the main body operation unit 52 on the document creation screen (S102). Usually, key input is performed from the numeric keypad (consisting of numeric keys 0 to 9, # key, * key) of the main body operation unit 52. For example, the key “2” is assigned to the number 2 key, and is pressed once to input “KA” and pressed five times to input “KO”. The character string input in this way is input to the FEP 54 through the input switching means 53 (S103) (S104) (note that the input switching means 53 may be bypassed). The FEP 54 converts the input character or character string into, for example, kanji, hiragana, katakana, alphanumeric characters, symbols, pictograms, fixed phrases, etc. (S104). The document created on the document creation screen is temporarily stored in the memory 58 of the main body (S105), and the document is appropriately transmitted to the partner apparatus by mail software (S106).

(2) When the external operation unit and the mobile phone are connected via USB In this case, the device I / F 591 of the external operation unit 59 and the host I / F 56 of the mobile phone are connected via the W-USB interface. . When the host I / F is provided on the main body side (cellular phone) in this way, the function can be easily expanded by connecting other peripheral devices having various functions including the device I / F.

The connection process and the disconnection process in this case will be described with reference to FIGS. First, the mobile phone 50 and the external operation unit 59 are connected via a W-USB interface. As an example of connection, W-USB starts communication with each other by simultaneously pressing a connection key on the main body side and a connection key on the external operation unit side (connection processing start: S81). The connection work (authentication work) is performed (S82). As the connection key, a dedicated key may be newly provided, or a plurality of existing keys may be simultaneously pressed. The connection is started when the authentication is established, but information at the time of authentication (information on the partner device, status information, communication record, etc.) is stored in the memory 58 of the own device. If the connection is successful (S83), the detection unit 57 detects that the external operation unit 59 is connected (S84), so the input switching unit 53 receives the input from the main body operation unit 52 from the external operation unit 59. (S85), and the key input of the external operation unit received via the W-USB interface is transmitted to the FEP 54. This switching may be automatically performed by detecting the connection by the detection means 57 when the external operation unit 59 is connected by W-USB, or by a user operation without providing the detection means 57. It may be switched. Further, the input from both operation units may be transmitted to the FEP 54 without switching the input from the operation unit. Further, there are two types of FEP 54 (for the main body keyboard and for the external keyboard), which may be switched as appropriate. Next, the application is activated (S86) to input a document . Even when connected via W- USB or when receiving input information, other operations such as receiving mail or responding to incoming calls can be performed in parallel.

  When disconnecting the W-USB connection, the communication disconnection protocol sequence is executed by pressing the disconnect key on the main body side or the external operation unit side (S91). At this time, since the detection means 57 detects that the external operation unit 59 is disconnected (S92), the input switching unit 53 switches to the input of the main body operation unit 52 (S92). Or you may switch by the switching setting by a user's operation, without providing the detection means 57. FIG. If there is no next input even after a predetermined time has elapsed since the last input from the external operation unit 59, the W-USB connection may be disconnected, or the main body side or the external operation unit side W-USB may be disconnected. May be shifted to an energy saving mode in which the power supply to the display unit 51 or the backlight unit on the main body side or the backlight unit is stopped. At this time, the energy saving mode may be canceled when an input from the external operation unit 59 or an operation for instructing a return from energy saving is performed again.

Further, when a keyboard (particularly a full keyboard) used in a personal computer is used as the external operation unit 59, key input is much easier or easier than key input using the main body operation unit 52 (the number of key inputs). Less).
(Mobile terminal device)
As another embodiment of the present invention, for example, a method of fixing the spread angle of a foldable mobile phone will be described with reference to FIG. The current normal foldable mobile phone has the structure shown in FIG. 12 (A), and is in a closed state in order to make a phone call or to carry mail or the Internet by hand. As shown in FIG. 2, it is sufficient that there are two kinds of states in an open state (an angle smaller than 180 degrees for easy operation), and there is no use at an intermediate angle. However, in the present invention, since a keyboard is connected to a mobile phone, it is assumed that the mobile phone is placed on a table or the like with the mobile phone open. In that case, when it is opened and placed at an angle close to 180 degrees, there is a drawback that the angle is too wide and it is difficult to see the display screen. One embodiment of the present invention solves such a problem.

  Therefore, as shown in FIG. 12 (C), a rotation mechanism (movable part) is provided with a lock mechanism so that it can be fixed at several angles (P2, P3, etc.) between 90 degrees and 180 degrees. It is. This lock mechanism is fixed by providing a groove or a protrusion at a portion corresponding to a predetermined angle (an angle to be fixed) on the rotation direction side of the rotation shaft. In addition, a lock mechanism may be provided at a plurality of angles, but it may be fixed in a stepless manner so that it cannot be rotated unless a certain amount of force is applied in the direction of rotation. The present invention is not limited to scenes input from the external operation unit 59, and can be used, for example, when viewing a portable TV or viewing other image displays.

  When the main body is placed as shown in FIG. 12B, there is a problem that the external operation unit 59 and the mobile phone 50 collide with each other, and the layout is limited.

In this case, as shown in FIG. 13, a mechanism that opens more than 180 degrees may be provided so that the operation unit 84 of the main body faces downward and is placed on a table or the like. By doing so, the external operation unit 81 can be placed near the display screen of the main body, so that the user's favorite arrangement can be realized (the degree of freedom of layout of the external operation unit 59 is increased). In this case, the key input of the main body operation unit 52 may be ignored. Further, the lock mechanism described above may be provided.
(Power supply to peripheral devices)
The power supply to the peripheral device will be described with reference to FIG. When a peripheral device that does not have a power supply is connected to the main body of the mobile phone, it may be necessary to supply electricity from the main body to the peripheral device. However, in the case of a mobile phone that uses a battery as the power source, When electricity is supplied, there is a problem that its own power source is consumed quickly.

Therefore, when a peripheral device that does not have a power supply is connected to the main body of the mobile phone (S95), when the power (electricity) is supplied to the mobile phone (when the power adapter is connected, the case of Y in S96). In addition, when the power (electricity) is supplied to the peripheral device (S97) and the power (electricity) is not supplied to the mobile phone (when the power adapter is not connected, N in S96), the peripheral device Electricity (power supply) is not supplied (S98).

  For this processing, the mobile phone has power adapter detection means for detecting whether or not the power adapter is connected and power supply means for peripheral devices, and the power adapter detection means detects connection of the power adapter. When the detection unit 57 in FIG. 8 detects the connection of the peripheral device, the power supply unit supplies power to the peripheral device.
