Description

  The present invention relates to a data processing system in which a host device such as a PC and a portable wireless terminal device are connected via an interface such as USB (Universal Serial Bus), a data transmission method in the system, and a portable wireless terminal device.

  A mass storage device (in this case, a portable wireless terminal device such as a mobile phone equipped with an external memory such as a memory card, which supports a USB communication mass storage class transfer protocol) is connected to a USB interface of a host device such as a PC. A USB mass storage technology that can be used as a removable medium is known.

  FIG. 6 shows an example of a mass storage mode start / end sequence in the USB mass storage technology. Here, a host device such as a PC, a USB driver and a mass storage application installed in a mobile phone, and a flow of inter-protocol processing for controlling communication are shown. The process flow will be briefly described below.

  First, when a USB cable is connected between the PC and the mobile phone (step S601), the USB driver reads data from the PC in order to treat the mobile phone (external memory mounted on it) as a mass storage device. A USB cable connection notification is issued to the mass storage application that controls the data folder in response to reading or writing (step S602). Upon receiving this, the mobile phone activates a mass storage application implemented as one of the application programs (step S603), and displays a screen for prompting the user to select the USB mode (step S604). When mass storage mode selection is performed by a user operation (step S605), a radio wave OFF setting request is issued to the protocol (step S606).

On the other hand, after setting the radio wave OFF and setting the mobile phone in a communication disabled state, the protocol issues a radio wave OFF setting completion notification to the mass storage application (step S607). A USB mode (mass storage mode) for handling the mobile phone as a USB device is set for the USB driver (step S608). The PC detects that the USB device is connected by pulling up the D + line of the connected USB cable (step S609), and thereafter, the negotiation process is performed between the PC and the USB driver. It is executed (step S610).
Here, the negotiation process is to check specifications such as an operating speed (12 Mbps or 480 Mbps) that can be used with a USB driver mounted on a mobile phone by a PC, and the external memory connected to the mobile phone The PC recognizes that it operates in the storage mode. The PC waits for the completion of the negotiation process (step S611), activates its own mass storage application program (step S613), and the USB driver A USB negotiation completion notification is issued to the mobile phone mass storage application (step S612). As a result, data transfer by the USB protocol is started between the PC and the mobile phone (step S614).

  On the other hand, when the data transfer ends or an unexpected situation occurs and the USB cable is disconnected (step S615), the PC detects this and ends the execution of the mass storage application program (step S616). Also, the USB driver issues a USB cable disconnection notification to the mobile phone mass storage application (step S617). In response to this, the mass storage application issues a radio wave OFF release request to the protocol (step S618), and the protocol receiving the protocol restores the mobile phone to a communicable state, and An OFF release completion notification is issued (step S619). Then, the mobile phone main body ends the above-described series of mass storage mode start / end sequences by terminating the mass storage application (step S620).

Using the above-described USB mass storage technology, for example, a USB storage device that prevents data corruption due to disconnection of a cable during data transfer of the mass storage device (see, for example, Patent Document 1), storage due to battery exhaustion during data transfer of the mass storage device There is also known a data transmission system (for example, see Patent Document 2) that prevents damage to the apparatus and data loss.

The main memory 12 stores a mass storage application, and the CPU 11 sequentially reads and executes the mass storage application stored in the main memory 12, thereby implementing the USB interface 30 and the mobile phone 3. Data transmission control is performed using the portable wireless terminal device 3 (storage unit 37) as a mass storage device via the interface 30.
Specifically, when the communication unit 31 of the mobile phone 3 is shifted to an unusable state after the negotiation process with the mobile phone 3 is completed, the CPU 11 starts measuring a predetermined time and until the predetermined time elapses.

Here, when the mobile phone 3 is connected as a USB device, and the mobile phone is connected via the USB cable 2, the CPU 11 is automatically recognized by the installed OS (Operating System) and a USB driver necessary for processing is installed. It has become a mechanism.

4 and 5 are diagrams for explaining the operation of the data processing system according to the embodiment of the present invention. Incoming inquiry sequence in the mass storage mode (FIG. 4), incoming call in the mass storage mode Each of the sequences (FIG. 5) when there is
4 and 5, the mass storage application (CPU 11) installed on the PC 1, the USB driver (USB driver control unit 381) installed on the mobile phone 3, and the mass storage application MSAPL (mass storage class control) The flow of operation between the parts 382) is shown.

  The operation of the data processing system according to the embodiment of the present invention shown in FIGS. 1 to 3 will be described in detail below with reference to the sequence diagrams shown in FIGS.

  First, an incoming call inquiry sequence in the mass storage mode will be described with reference to the sequence diagram of FIG.

  First, the USB cable 2 is connected between the PC 1 and the USB interfaces 10 and 30 of the mobile phone 3, and when starting USB transfer between these devices, the control unit 38 (USB driver control unit of the PC 1 and the mobile phone 3). 381), a USB negotiation process is executed (step S401). Here, the USB negotiation process is, for example, as shown in the sequence diagram of FIG. 6, when the PC 1 detects the connection of the mobile phone 3 (for example, by pull-up connection of the D + line of the USB cable 2). The specification of the operating speed (12 Mbps or 480 Mbps) that can be used with the USB driver mounted on the mobile phone 3 is confirmed, and the external memory (the storage unit 37 in FIG. 2) connected to the mobile phone 3 is mass storage. This is a process for recognizing operating in the mode.

  When the above-described negotiation processing is completed, the USB driver control unit 381 (USB driver) issues a USB negotiation completion notification to the MSAPL (mass storage class control unit 382) that is operating (step S402) while the radio wave is OFF. (Step S403).

  By the way, the radio wave OFF is a function of stopping transmission / reception of radio waves from the communication unit 31. This is a state in which the transmission / reception operation of the communication unit 31 is stopped when a radio wave OFF is requested from an application program that manages a communication protocol for performing communication with the network. Of course, wireless communication is not performed in this state.

On the other hand, upon completion of the USB negotiation process, the PC 1 (CPU 11) activates the mass storage application stored in the main memory 12 (step S404), and activates the incoming call inquiry timer in the mass storage application (step S404). S405). Then, a data transfer request (WRITE DATA) in the bulk mode is issued to the control unit 38 (USB driver control unit 381) of the mobile phone 3 (step S406), and the OUT token and the transfer data are transmitted (each step). S407, S408).
Receiving this, the USB driver control unit 381 writes the transfer data in the data area of the storage unit 37 via the main control unit 380 (step S409), and transmits an ACK packet to the PC 1 (step S410). The PC 1 that has received the ACK packet transmits an OUT token and subsequent transfer data (steps S411 and S412), and the control unit 38 (USB driver control unit 381) of the mobile phone 3 that has received the ACK packet via the USB interface 30 Then, the transfer data is written in the data area of the storage unit 37 via the main control unit 380 (step S413), and an ACK packet is transmitted to the PC 1 (step S414).

The above operation is repeatedly executed for a predetermined amount of data included in the data transfer request. The PC 1 (CPU 11) executes the mass storage application so that the incoming call inquiry timer is started first. When the time has expired in this incoming call inquiry timer (step S415), the first data transfer is performed. A request for an incoming call is requested to the mass storage class control unit 382 (MSAPL) via the USB driver control unit 381 (USB driver) of the mobile phone 3 using a vendor-specific request (steps S416 and S417).
The mass storage class control unit 382 that has received the incoming call inquiry request executes a radio wave OFF release process for setting the communication unit 31 of the mobile phone 3 to the usable state (step S418). Subsequently, the mass storage class control unit 382 activates the communication processing unit 383 via the main control unit 380, and the communication processing unit 383 makes an inquiry about a new mail to a network side device (mail server) (not shown) (step) S419), the result (whether there is a new mail or answering machine) is acquired and handed over to the mass storage class control unit 382 via the main control unit 380 (step S420).

  Here, if it is confirmed that there is no new mail, the mass storage class control unit 382 performs a radio wave OFF setting process for disabling the communication unit 31 to the communication processing unit 383 via the main control unit 380. This is executed (step S421), and an inquiry result notification (no new mail) is issued to the USB driver control unit 381 via the main control unit 380 (step S422).

By the way, the PC 1 (mass storage application) issues an IN token to the USB driver control unit 381 of the mobile phone 3 in order to confirm whether or not the incoming call inquiry is completed after issuing the incoming call inquiry request in step S416. It is issued continuously (steps S423 and S425), and if the incoming call inquiry is not completed, a NAK packet is transmitted as a response (steps S424 and S426).
After receiving the inquiry result notification from the mass storage class control unit 382, the USB driver control unit 381 performs mass storage class control on the IN token received by the CPU 11 executing the mass storage application (step S427). An inquiry result notification (no incoming call) delivered from the unit 382 is issued (step S428). Receiving this, the CPU 11 (mass storage application) transmits an ACK response to the USB driver control unit 381 of the mobile phone 3 (step S429), and at the same time, starts the next incoming call inquiry timer (step S430). According to the previous inquiry result, since there was no incoming call, a data transfer request (WRITE DATA) is issued for the next data transfer (step S431), and an OUT token and transfer data are transmitted (steps S432 and S433). Upon receiving this, the USB driver control unit 381 of the mobile phone 3 writes the transfer data in the data area of the storage unit 37 (step S434), and returns an ACK response to the CPU 11 (mass storage application) (step S435). ).

  According to the above-described embodiment of the present invention, the mass storage class control unit 382 (MSAPL) has been described as inquiring the mail server via the communication processing unit 383 as to whether or not there is a new mail. 382 (MSAPL) may issue a mail confirmation request to the mail application that is also mounted on the mobile phone 3, and the mail application may inquire the mail server.

  Next, an incoming call inquiry operation in the mass storage mode will be described with reference to the sequence diagram of FIG.

  Basically, the mobile phone 3 which is a USB device shifts to the radio wave OFF mode when there is no incoming call, and responds to the data transfer request from the PC 1 with an ACK in the incoming inquiry sequence in the mass storage mode shown in FIG. Accordingly, steps S501 to S518 correspond to steps S401 to S418 in FIG. 4 and steps S524 to S527 correspond to steps S423 to S426 in FIG. 4, respectively. The display unit 36 displays whether or not to end the mode, and is different in that the mass storage mode is ended by the user's end selection. The detailed description will be given below.

That is, the mobile phone 3 (communication processing unit 383) first makes an inquiry about new mail via the communication unit 31 to the mail server of the network side device after the radio wave OFF cancellation processing by the mass storage class control unit 382 (step S518). Is performed (step S519). If there is a response from the mail server that there is an incoming voice call (answering machine) or incoming mail (step S520), the communication processing unit 383 sends the response to the mass storage class control unit 382 via the main control unit 380. As a result, the mass storage class control unit 382 generates a message such as “New mail exists / does the mass storage mode end” and displays the message on the display unit 36 via the main control unit 380. (Step S521).
Then, the mass storage class control unit 382 issues a mass storage mode end request to the USB driver control unit 381 in response to a mass storage mode end selection request acquired by the user operating the operation unit 32 (step S522). (Step S523).

Upon receiving the mass storage mode end request, the USB driver control unit 381 pulls down the D + line of the USB cable 2 to make it appear to the PC 1 as being disconnected from the USB cable (while the power is still supplied), and reconnects the USB cable 2. Is issued (steps S528 and S529).
Then, the PC 1 (CPU 11: mass storage application) that has received the reconnection request for the USB cable 2 terminates the mass storage mode, so that the PC 1 (USB driver control unit 381) is a USB device. Negotiation processing for connecting the cable 2 in the modem mode is started (step S530), the modem negotiation is ended (step S531), and the incoming call sequence in the series of mass storage modes is ended.

  As described above, according to the data processing system of the embodiment of the present invention, during data transfer, the PC 1 (mass storage application) receives an incoming call at the timing when the first data transfer is completed after a predetermined time has elapsed.
