Description

  The present invention relates to an information communication device, and more particularly, to an information communication device capable of data communication with an information device such as a personal computer and telephone and data communication via a wired or wireless telephone network.

2. Description of the Related Art Conventionally, mobile phones have a data communication function for transmitting and receiving e-mails and the like with other mobile phones in addition to a function for making calls with other mobile phones and telephones connected to a general subscriber telephone line via a telephone network. .
Also, a memory for storing incoming data such as e-mails in an internal memory, which has a call function for making a phone call and a call detection function for detecting an incoming call from another telephone in order to make a call or data communication It has a function.

In addition, some mobile phones are equipped with a connector for connecting a USB cable, which is connected to an information device such as a personal computer with a USB cable to transfer received e-mails to a personal computer or setting data such as a phone book from a personal computer. Some have a function of receiving data to be transmitted and storing it in an internal memory (for example, see Patent Document 1).
When the mobile phone described in Patent Document 1 is connected to a personal computer via a USB cable, the mobile phone is used as an external storage device of the personal computer.
JP 2002-359694 A

However, in the device described in Patent Document 1, data communication is possible with a personal computer in a state where the personal computer is connected to the personal computer with a USB cable, but communication or data communication via the telephone network is not possible. That is, the outgoing call function and the incoming call function are stopped, and the mobile phone can operate only as an external storage device of a personal computer.
Therefore, even if the mobile phone with the USB cable connected receives an incoming call, the incoming call is rejected, and the owner of the mobile phone cannot know that the incoming call has been received. In other words, even if a person who wants to make an urgent call to the owner makes a call, if the owner's mobile phone is connected to the USB cable, the call cannot be accepted and the call cannot be made. It was.

In addition, when an incoming call is received from a telephone network to a conventional mobile phone, the internal memory of the mobile phone is rewritten to update the incoming call history, and an e-mail or the like is received from the telephone network. In the case of a failure, the internal memory is rewritten to save the received data.
When the mobile phone is used as an external storage device such as a personal computer, the internal memory is generally managed with a file system structure such as FAT. However, simply using an external storage device to simply accept incoming calls from the telephone network will cause rewriting of the internal memory at the time of incoming calls, resulting in inconsistencies or destruction of data stored by the personal computer. There is also.
That is, the same storage area may be destroyed by overwriting data.

FIG. 10 is an explanatory diagram when inconsistency or destruction of data written from the personal computer to the internal memory occurs.
FIG. 10A shows a part of the data stored in the internal memory of the mobile phone before the connection with the USB cable.
FIG. 10B shows a state in which a USB cable is connected and a part of the data on the personal computer is changed by text editing on the personal computer.

In this state, if there is an incoming call and the incoming call history is updated, the data in the first and second lines (1 September 13) is stored in the internal memory of the mobile phone as shown in FIG. 15:00, T book 090-1357-1357) is added.
After that, when an instruction to save the edited data is executed from the personal computer, the internal memory of the mobile phone becomes one of the three states shown in FIG. 10D, and data inconvenience may occur.
(I) in FIG. 10 (d) shows a case where the incoming call history is deleted, and (II) shows a case where inconsistency occurs in a part of the edit data to be stored. ) Shows a case where the data in the internal memory is completely destroyed and cannot be read out.

  In order to perform data communication with a personal computer and data communication at the time of incoming from the telephone network in parallel during the same time period, an area for storing data written from the personal computer and data written at the time of incoming from the telephone network It is necessary to manage the internal memory of the mobile phone by completely dividing the area for storing the mobile phone. However, it is difficult to completely separate and manage data shared by both data communications, such as the telephone number of the other party, and care must be taken to prevent unintended rewriting or destruction.

  Therefore, the present invention has been made in consideration of the above circumstances, and calls and data communication via a telephone network and data communication with an information device such as a personal computer are performed in parallel at the same time zone. It is an object of the present invention to provide an information communication apparatus that can perform data or prevent data inconsistency from occurring even if both data communications compete.

The present invention stores a first communication unit that performs communication via a telephone network, a second communication unit that performs data communication with an information device, and information communicated by the first communication unit and the second communication unit. A storage unit, and a control unit that controls the communication by the first communication unit and the communication by the second communication unit to be executed in parallel, and is received by the storage unit via the first communication unit. A first storage area for storing information and a second storage area different from the first storage area for storing information communicated via the second communication unit, and the first storage The information stored in the area is stored in a structure that cannot be read from the information device .

  According to this, incoming calls can be received during use as an external storage device, user convenience can be improved, and data destruction does not occur. Even during communication, incoming calls and data can be received.

  The information received via the first communication unit stored in the first storage area is written to the second storage area after communication with the information device is completed. An information communication apparatus is provided.

In addition, an interface unit for connecting to the information device,
The interface unit may include a mechanism that realizes at least one of USB connection, wireless LAN connection, or Bluetooth connection.
In addition, when the display unit further includes a display unit and the display unit performs communication via the first communication unit and communication via the second communication unit in parallel during the same time period, You may make it display distinguishing what is being done.

  Furthermore, the display unit displays a first display unit indicating that communication is being performed via the first communication unit, and a second display indicating that communication is being performed via the second communication unit. It may be made up of parts.

According to the present invention, the first data communication via the telephone network and the second data communication with the information device are controlled to be executed in parallel in the same time zone. Even if there is a conflict between the use of the phone and the incoming call and data reception, both can be prevented from causing inconvenience.
Further, the storage areas of the respective information used in the first data communication and the second data communication are divided, and the first received data received in the first data communication is used in the second data communication with the information device. Since the data is stored in a first data storage area different from the second received data, it is possible to prevent data inconsistency or destruction without special setting or operation by the user.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. In addition, this invention is not limited by this.

The control unit 5 mainly includes a CPU, a ROM, a RAM, a timer, an I / O interface, an interrupt control unit, and the like. Realized by a computer. The operation of each functional element unit is realized by the CPU operating the hardware based on a program stored in the ROM or the like.

In addition, the control unit 5 has an incoming call detection function, and when detecting that there is an incoming call from the telephone network 20, the control unit 5 executes incoming call processing by interrupt control. For example, if an incoming call is received from another telephone while operating as an external storage device of an information device, an interrupt process occurs when the incoming call is detected, and a speaker (not shown) The microphone can exchange signals with the RF communication unit 7.
Alternatively, when there is an incoming call for the purpose of sending an e-mail from the telephone network 20, when the incoming call is detected, the e-mail is received and stored in the storage unit 4 by interruption processing.

  When the information device 41 is connected to the information communication device 1 of the present invention via a USB cable, the connection is detected, and then the storage unit 4 functions as an external storage device of the information device 41 to perform USB communication. The communication program PG1 that implements the function of the external storage device is activated so that data communication can be performed with the information device 41 via the unit.

FIG. 2 shows a schematic flow when a USB cable is connected to the information communication apparatus of the present invention. First, in step S1, it is checked whether a USB cable is connected. If it is detected that it is connected, the function as the external storage device is activated (step S2).
If an incoming call is received from the telephone network 20 while the program PG1 is in operation, an interrupt process for the CPU is activated after the incoming call is detected, and a process based on the incoming call (for example, a mail receiving process) is executed. Is done.
According to this, even during data communication with the information device 41, processing for incoming calls from the telephone network can be executed in real time by interruption processing, so that incoming calls to the user can be accepted at any time.

Next, a process for detecting that a USB cable is connected to a USB connector provided in the USB communication unit 10 will be described.
FIG. 3 shows an explanatory diagram of an embodiment for detecting the physical connection of the USB cable. Here, a state is shown in which the information communication apparatus 1 of the present invention and a personal computer (information device 41) are connected via a USB cable. The USB cable has four cores, and consists of two power supply lines (V = 5V, GND) and two data lines (D +, D-). When a USB cable is connected, the four lines are connected to terminals having the same meaning.

At this time, a voltage of +5 V is supplied from the personal computer 41 side to the information communication apparatus 1 of the present invention to the terminal to which the V = 5 V line is connected. Therefore, a circuit for monitoring the voltage of the terminal connected to the V = 5V line is provided in the communication control unit, and the presence / absence of the + 5V voltage is detected.
If a voltage of +5 V is detected here, it is determined that the USB cable is connected. Otherwise, it is determined that the USB cable is not connected. This + 5V voltage detection signal is given as an interrupt signal to the CPU of the control unit 5 via the communication control unit 6.

FIG. 4 shows a flowchart of processing for software detection that the USB cable is connected.
First, in step S11, when + 5V of a line of V = 5V is detected, an interrupt signal corresponding thereto is given to the control unit 5.
In step S12, when the interrupt signal is given to an interrupt controller (INTC) provided in the control unit, the INTC transmits an interrupt signal indicating that something is connected to the connector unit to the CPU.

  In step S13, when the CPU receives a signal from the interrupt controller, in step S14, the CPU determines which interrupt is the interrupt. If it is recognized that the interrupt is due to USB connection, the process proceeds to step S15, and a predetermined application program is loaded so that communication can be performed via the USB driver and the USB cable.

Next, in step S16, it is checked whether a command meaning that transmission / reception is possible is sent from the personal computer side. When a command is transmitted, in step S17, either the D + line or the D− line is pulled up, and along with the USB speed selection, the logical connection for USB communication is completed on the personal computer side. Tell.
When the above processing is completed, the information communication apparatus 1 and the personal computer 41 are ready for data communication via the USB cable.

FIG. 5 shows a flowchart of an embodiment in the case where two data communications are performed in parallel in the present invention.
FIG. 5A is a flowchart of data communication processing with a personal computer via a USB cable.
FIG. 5B is a flowchart of data communication via the telephone network performed by interrupt processing.
FIG. 6 is a schematic explanatory diagram of the internal configuration of the storage unit 4.
In FIG. 6, the storage unit 4 is roughly divided into two areas (Data A, Data B). The DataA area is an area for temporarily writing data received when an incoming call is received (first data storage area 14), and the DataB area is a storage area for data transmitted / received by data communication with a personal computer (second data storage). Region 15).

The Data B area has a file system structure that can be accessed from an external information device 41 such as a personal computer. For example, it is assumed that it is formatted in the FAT structure as shown.
Thus, by storing data in the DataB area in the FAT structure, data can be written to this area from a personal computer or the like, and the data stored in this area can be read out.

  On the other hand, the DataA area stores data in a structure that cannot be read by an external information device 41 such as a personal computer. As a result, the data written in the DataA area cannot be accessed from a personal computer or the like, and can be prevented from being rewritten by an unintended write command from the personal computer. That is, as shown in FIG. 6A, if data (DataT) such as an e-mail received by an incoming call is written in the area of DataA, in the state of FIG. 6A, in the area of DataB, Even when data is read from or written to the personal computer, the data (DataT) written by the incoming call is not destroyed.

Further, as shown in FIG. 6B, when data communication with the personal computer is completed, for example, when the USB cable is disconnected, received data (DAtaT) by the incoming call is transferred from the DataA area to the DataB area at a predetermined position. Write to.
For example, if the received data (DataT) is an e-mail, it may be written in a predetermined e-mail storage area in DataB.
Since data is written to the DataB area after the data communication with the personal computer is completed, there is no contention with the data communication with the personal computer, and simultaneous access to the same area is prevented. Never happen.

DataT written in the DataB area can then be accessed from the personal computer and transferred to the personal computer as necessary. Here, DataT temporarily stored in the DataA area may not be erased as it is, but may be erased as needed after writing to the DataB area.
Such data communication processing will be described based on the flow of FIG.

In FIG. 5A, it is assumed that data communication is performed with a personal computer via a USB cable (step S31). That is, it is assumed that reading and writing are performed on the DataB area.
In step S32, it is checked whether or not all data has been transferred. If the transfer of all data has not been completed, the data transfer is continued as it is.

When the transfer of all the data is completed, the process proceeds to step S33, and it is checked whether the incoming interrupt process of FIG.
If the incoming interrupt process has not been executed, the data process is terminated as it is. On the other hand, if the incoming call interrupt process has been executed, the process proceeds to step S34 to check whether the incoming call interrupt process has ended. If the incoming interrupt process is completed, the process proceeds to step S35. If there is data (DataT) written in the DataA area in the incoming interrupt process, DataT is copied to the DataB area.
That is, the data written in the DataA area is copied to the DataB area accessible by the personal computer when data communication with the personal computer is not performed.

On the other hand, the incoming interrupt process shown in FIG. 5B is executed every time an interrupt signal is detected regardless of the process shown in FIG.
That is, when the interrupt process is started, in step S41, signal switching or the like is performed so that data communication with the telephone network 20 can be performed via the RF communication unit 7 after the incoming call. In step S42, the telephone network 20 The data (DataT) sent from is received, written in the DataA area of the storage unit 4, and the interrupt process is terminated.

  By executing the above two processes in parallel in real time, it is possible to receive data by an incoming call during data communication with a personal computer, and data (DataT) can be received in a state where data communication with the personal computer is completed. Since writing is performed in the DataB area, inconsistency and destruction of data stored in the DataB area can be prevented.

FIG. 7 shows a flowchart when the USB cable is removed.
In step S21, it is checked whether or not the physical connection of the USB cable is lost in a state where it is recognized that the USB cable is currently connected. That is, it is checked whether or not the power supply of the + 5V terminal of the USB cable is lost. When the power supply is lost, the process proceeds to step S22, and the external storage device function (program) is stopped.
Thereby, the data communication with the personal computer is completely terminated.
