Problems solved by technology

[0003] To sum up, how to solve the problem that users can perform CS and PS services at the same time, and how to solve other tasks that can be executed in parallel but cannot be executed in parallel due to the unavailability of channel resources, this technical invention is proposed. Multiple USB channels can be virtualized through a USB device of the wireless network card, which can provide a dedicated channel for any task that requires an exclusive channel, and can use any communication protocol specified by itself for the processing of channel data, that is, the purpose of the present invention is to provide A method for wireless network card to realize multi-channel to achieve multi-task execution in parallel at the same time

Embodiment Construction

[0008] Combine below figure 1 A preferred embodiment of the present invention is given and described in detail so that those skilled in the art can more easily understand the technical features and functional characteristics of the method of the present invention, rather than to limit the scope of the present invention.

[0009] Concrete implementation method steps of the present invention are as follows:

[0010] S 1 , First, a plurality of USB channel interfaces are virtualized in the driver layer to the USB device of the wireless network card, and the number of the USB channel interfaces is determined according to needs, and three USB channel interfaces are provided in the present embodiment;

[0011] S 2 . Use channel 1 as an exclusive data service processing channel, that is, as a modem on the PC side. Using this channel can be used for data service processing, that is, dial-up Internet access, which can be managed through the PC-side interface management program or PC ...

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

technical field [0001] The invention relates to a method for a wireless network card module to use multiple channels to perform multiple tasks in parallel. Background technique [0002] Nowadays, the common wireless network card cannot perform any other operations because the AT channel is occupied when performing online services, and can no longer respond to other AT commands. Similarly, services such as video calls cannot be performed at the same time. For 3G users Generally speaking, the network supports the parallel execution of CS and PS services. However, in some cases, such as when the wireless network card is dialing up, due to the unavailability of channel resources, many tasks cannot be responded at the same time or need to be delayed. The CS and PS services cannot be processed at the same time, and the tasks that could have been executed in parallel cannot be executed in parallel due to the unavailability of channel resources. Contents of the invention [0003]...
