Abstract

The invention provides a method for implementing the parallel execution of multiple tasks in a wireless network card module in the multi-channel mode. Since the wireless network card module is not provided with a keyboard and a display screen, a user controls the wireless network card module only via the USB channel or serial port. Generally, the standard control method is the AT command. But in some instances, for example, the wireless network card occupies the AT command exclusively, which leads to the response failure or delayed processing of the voice operation, the short message operation and the like or delayed time processing. In order to solve the problem, the method adopts the multi-channel mode and ensures the parallel execution of the multiple tasks such as voice operation, short message operation and dial-up internet access.

Description

Wireless Internet card realizes that multichannel is to reach multitask parallel executing method simultaneously

Technical field

Parallel executing method when the present invention relates to a kind of card module of getting online without being tethered to a cable and use multichannel to carry out multitask.

Background technology

General wireless Internet access now is stuck in when carrying out business of networking can not carry out other any operations because the AT passage is occupied, can't respond other AT order again, equally, business as being similar to visual telephone just can't be carried out simultaneously, for 3G subscription, the executed in parallel of network support CS and PS business, but, wireless Internet card in some cases as when dialling up on the telephone because the unavailable of channel resource causes a lot of tasks not respond simultaneously or needs delay processing, thereby, make the user can not carry out the processing of CS and PS business simultaneously, also make originally can executed in parallel task owing to channel resource unavailable causes it can not executed in parallel.

Summary of the invention

In sum, how to solve the user and can carry out CS and PS business simultaneously, and how to solve some other can executed in parallel task but owing to channel resource unavailable cause can not executed in parallel problem, this technological invention has been proposed, a USB device by wireless Internet card fictionalizes a plurality of USB passages, can provide special-purpose passage for any task of exclusive access that needs, can use any communications protocol of oneself stipulating to the processing of channel data, also promptly the object of the present invention is to provide a kind of wireless Internet card to realize that multichannel is to reach multitask parallel executing method simultaneously.

Technical scheme of the present invention is as follows:

The method of executed in parallel when a kind of card module of getting online without being tethered to a cable according to the present invention uses multichannel to carry out multitask: comprise the steps: S ₁, fictionalize a plurality of USB passages by a USB device of wireless Internet access card module; S ₂, the passage of special-purpose dialing access service is provided; S ₃, the passage of special-purpose common AT command response is provided; S ₄, provide special-purpose passage to carry out the Business Processing that other special duties of wireless Internet card transmit such as view data.

Advantage of the present invention is: at any time wireless Internet card can not postpone maybe can not respond any real-time Business Processing, and multichannel realization can allow the user indiscriminately ad. as one wishes carry out multiple services while parallel work-flow.

Description of drawings

Fig. 1 is the structure chart of wireless Internet card USB channel interface.

Embodiment

Provide a better embodiment of the present invention below in conjunction with Fig. 1, and described in detail, make those skilled in the art can be easier to understand the technical characterictic and the function characteristics of the inventive method, rather than be used for limiting scope of the present invention.

Specific implementation method step of the present invention is as follows:

S ₁, at first the USB device of wireless Internet card is fictionalized a plurality of USB channel interfaces driving layer, the number of USB channel interface determines as required, and three USB channel interfaces are provided in the present embodiment;

S ₂, with passage 1 as private data processing passage, the modem of just holding as PC, use this passage can be used for carrying out the processing of data service, just dial up on the telephone, interface management program that can be by PC end or the dial-up program of PC system dials up on the telephone;

S ₃, with passage 2 as special-purpose AT command response passage, such as some interaction process relevant with wireless Internet card of note, voice call, wireless Internet card module controls etc., comprise the response of all standard AT commands and the response of the AT command interface that some users oneself define, in the occupied situation of online passage, this designated lane can not block any AT order, can in time respond user's operation, and in time report the current status information of wireless Internet card in addition;

S ₄, with passage 3 as other special-purpose passages, such as can be used as the view data Transfer pipe, for take pictures, visual telephone etc. some need the business of exclusive access that private data transport functions is provided.

Claims

1. a wireless Internet access card module realizes that multichannel to reach multitask parallel executing method simultaneously, comprises step:

S ₁, fictionalize a plurality of USB passages by a USB device of wireless Internet access card module;

S ₂, described a plurality of USB passages are carried out the processing of data service, sending and receiving network packet with one of them designated lane;

S ₃, described a plurality of USB passages are responded common AT order with one of them designated lane;

S ₄, described a plurality of USB passages carried out special cell-phone function with one of them designated lane as required process.

2. wireless Internet access card module according to claim 1 realizes that multichannel to reach the simultaneously method of executed in parallel of multitask, is characterized in that step S ₃Respond common AT order with one of them designated lane and refer to other all standard AT commands except dialling up on the telephone, also comprise the AT order of user oneself definition.

3. wireless Internet access card module according to claim 1 realizes that multichannel to reach the simultaneously method of executed in parallel of multitask, is characterized in that step S ₄Carry out special cell-phone function with one of them designated lane as required and process, refer to provide the passage of a special use to carry out the transmission of view data in the occasion of visual telephone, process the send and receive of vedio data.
