Problems solved by technology

Moreover, the advantage of realizing voice communication in this way on the computer is: it not only enriches the means of communication between users, but also the communication fee is cheaper than using traditional mobile terminals; the disadvantage is that the user is bound to use the above-mentioned software on the computer
[0005] 1. Since the Bluetooth headset protocol is used as the voice channel, the analog voice signal is transmitted, so the scalability is poor, such as the audio data cannot be compressed for further expansion processing
[0006] 2. Since the Bluetooth headset protocol is not a general communication protocol, mobile terminal developers need to customize and modify the Bluetooth protocol stack on the existing mobile terminal. After that, users can use the mobile terminal to play and answer VoIP calls. , the solution cannot be implemented directly with existing mobile terminals

Embodiment Construction

[0072] The invention adopts short-distance wireless transmission mode to transmit digital signals, and the transmission mode is a general transmission protocol. It directly realizes the function of using the mobile terminal as a computer input and output device. Among them, the short-distance wireless transmission mode includes the mode of transmission using the Bluetooth transmission protocol. Furthermore, the Bluetooth transmission protocol includes the Bluetooth serial port protocol.

[0073] At the same time, a computer-side virtual audio drive unit is used to implement hardware simulation on the bottom of the computer. Moreover, due to the use of the computer-side virtual audio drive unit, two-way shielding and universal identification can be realized between the mobile terminal and the upper-layer VoIP application, such as QQ, MSN, Skype or Google Talk. Therefore, the use of the present invention has a good effect. Compatibility, can support popular instant messaging soft...

Abstract

The present invention discloses a system having a mobile terminal used as an input / output device of a computer, comprising a mobile terminal side audio input / output unit, a mobile terminal side sending / receiving unit, a computer side sending / receiving unit and a computer side virtual audio driving unit, wherein, the mobile terminal side audio input unit is adapted to collect audio data; the mobile terminal side audio output unit is adapted to play the audio data; the computer side virtual audio driving unit is adapted to have the mobile terminal used as the input / output device of the computer. The present invention further discloses a mobile terminal, a computer, and a method for the system. It is possible to, with an existing mobile terminal, directly have the mobile terminal virtualized as the input / output device of the computer by using the system of the present invention and the mobile terminal, the computer and the method thereof, so that users may use the mobile terminal to initiate and receive VolP calls.

Description

Technical field [0001] The present invention relates to virtual drive technology, and in particular to a mobile terminal as a computer input device / output device, a computer and a system and method for implementing the mobile terminal as a computer input and output device. Background technique [0002] Generally, a mobile terminal is used as a communication terminal, and its advantages are portability and mobility, enabling users to communicate with any other user at any time, any place, and any other users. At present, with the development of instant messaging software and VoIP communication software, a large number of software with voice communication functions have appeared on computers, such as Skype, MSN, QQ or Google Talk for realizing VoIP voice communication. Moreover, the advantages of implementing voice communication in this way on the computer are: not only the means of communication between users are enriched, but the communication fee is cheaper than using traditiona...
