Abstract
The invention relates to a communication control method of USB device, wherein the personal information terminal with internal USB device, when inputting energy-saving button, checks communication state of USB device; when it is communicating, inquiring the user about whether to interrupt the communication, and interrupting, via the request of user; at the same time, setting the sleep mode, therefore, it can normally stop the communication of USB device before setting sleep mode, to avoid communication error.
Description
Technical field
The invention relates to the communication control method of USB device, refer in particular to be equipped with personal information terminal (PDA:Personal Digital Assistant) the user when input power saving (PowerDown) button, can end to be arranged on the communication control method of USB device of the traffic operation of the USB device in the device selectively.
Background technology
Recently, the personal information terminal that property easy to carry and multimedia information storage function improve has greatly obtained widely popularizing, and the trend of appending the multiple USB device that is provided for carrying out multiple function and operation in the personal information terminal is also obvious further.
For example, above-mentioned personal information terminal inside can be provided with USB mobile communication module (USBCDMA Module) and USB controller chip, and the USB application program that is used to carry out mobile communication function and operation be when can being arranged on device interior, also can be chosen on the random-access memory (ram) in the CPU according to the user and move.
Simultaneously, above-mentioned personal information terminal is set dormancy (sleep) pattern when the user imports province's eletric button, carries out the power save function that reduces consumption of cell power supply.
But, the problem that exists is: ordinary individual's information terminal is when the above-mentioned province of input eletric button, unconditional automatic setting park mode under the state of not checking USB mobile communication module communications status is so be in the USB mobile communication module improper ground hang up of communications status.
Summary of the invention
Therefore, the present invention is for addressing the above problem, its purpose is to provide the communication control method of USB device, the personal information terminal that promptly refers to internal USB equipment is when the user imports province's eletric button, can before setting park mode, check the communications status of above-mentioned USB device, simultaneously select the normal termination traffic operation, set the communication control method of the USB device of park mode then according to the user.
To achieve these goals, the communication control method of USB device of the present invention comprises following 3 stages: the personal information terminal of internal USB equipment is checked above-mentioned USB device communication whether the 1st stage when input economizes eletric button; When above-mentioned USB device is being communicated by letter to user's query the 2nd stage of abort communication whether; Ending above-mentioned USB device traffic operation according to user applies when, set the 3rd stage of park mode.
The communication control method of USB device of the present invention with above-mentioned formation is very effective, promptly, whether the personal information terminal of internal USB equipment checks above-mentioned USB device communication when input economizes eletric button, when USB device is communicated by letter to the user's query abort communication whether, and end the traffic operation of above-mentioned USB device according to above-mentioned user applies, set park mode simultaneously, thereby can be before setting park mode the traffic operation of the above-mentioned USB device of normal termination, prevent in advance because the setting park mode produces communication error.

Embodiment
Communication control method to the USB device of this invention desirable embodiment is elaborated with reference to the accompanying drawings.
At first, the USB device that is used to carry out the numerous species of multiple function and operation can be appended and is arranged in the personal information terminal that is suitable for this invention, and USB mobile communication module 20 and USB controller chip 30 can be set in the above-mentioned as shown in Figure 1 personal information terminal.
In addition, above-mentioned personal information terminal inside be provided be used to carry out the USB application program of mobile communication function and operation in, also be provided with the power-supply controller of electric application program that is used for variable setting personal information terminal electric source modes, said procedure can be chosen on the random access memory in the central processing unit 10 according to the user and move.
Simultaneously, when above-mentioned CPU10 imports province's eletric button the user, move above-mentioned power-supply controller of electric application program, before setting park mode, check above-mentioned USB mobile communication module 20, then when above-mentioned USB mobile communication module is being communicated by letter, will inquire that by LCD 40 the navigational figure image of the selected whether abort communication of user is presented on the picture.
And above-mentioned CPU10 can be when the selected termination of user USB mobile communication module 20 traffic operations, the above-mentioned USB mobile communication module of control operation, and the normal termination traffic operation is set park mode then, prevents communication error in advance.Below this is elaborated.
The communication control method operational flowchart of Fig. 2 USB device of the present invention.As mentioned above, CPU10 is installed in the power-supply controller of electric application program (S10) of random access memory with operation, and when the user imports province's eletric button (S11), carries out the interface with above-mentioned USB mobile communication module 20, checks communications status (S12).
Simultaneously, when CPU10 is that USB mobile communication module 20 is not when being in communications status in above-mentioned check result, to set park mode (S18), when otherwise above-mentioned USB mobile communication module 20 is in communications status, then generate the navigational figure image be used to inquire whether abort communication operation, be presented at (S14) on the picture by above-mentioned LCD 40.
In addition, above-mentioned CPU10 is after being presented at navigational figure on the picture, as the non-selected communication of user Shen Zhishi, then do not consider the input (S16) of above-mentioned province eletric button, continue to keep current electric source modes, when the selected communication of user is ended then by with the interface normal termination traffic operation (S17) of above-mentioned USB mobile communication module 20.
And, owing to set current electric source modes for park mode (S18), carry out the power save function that is used to reduce consumption of cell power supply, so can be when setting park mode according to user applies, control the communication of USB mobile communication module normal termination in advance, communication error takes place in prevention.
Desirable embodiment of the present invention is exactly to find out for achieving the above object, this area staff fully can be in not departing from the technological thought and technical scope thereof that claim of the present invention puts down in writing, and other various embodiment are improved, change or additional etc.
