In the embodiment of the present invention, the mobile terminal may be a mobile phone with an Internet access and a WIFI function, and the digital terminal may be a computer with a WIFI function, an electronic device such as a PSP (Multi-Purpose Handheld). The wireless network may be a 3G network or other network having a PS (Packet Service, Data Service) function. The foregoing encoding and decoding can use various methods of codec of the prior art, and will not be described in detail herein.

In the following, the present invention will be further described by taking a wireless network as a 3G network and a mobile terminal as a 3G mobile phone as an example.

As shown in FIG. 2, it is a schematic diagram of an application scenario of an application example of the present invention, wherein a 3G mobile phone and a base station support a PS service and a CS (circuit service, ie, a voice service) of the mobile phone through a 3G wireless communication connection. At the same time, the WIFI routing module that comes with the 3G mobile phone and the WIFI routing module that comes with the digital terminal are interconnected through WIFI. The digital terminal can construct a Voice channel on the WIFI network between the mobile phone and the digital terminal through the installed Voice Service client. In this way, the digital terminal can access the Internet through the 3G network of the mobile phone through WIFI, and can also make a voice call through the network of the mobile phone through the voice channel based on WIFI.

The 3G mobile phone is familiar to the public through the mobile communication network for PS and voice services, without much introduction. For the present invention, the data and control process of the present invention can be understood by the system composition diagram shown in FIG.

The mobile phone has the functions of mobile communication through the 3G Module (3G communication module), including the PS service and the voice service. The mobile phone realizes interconnection with other digital terminals with the WIFI module through its own WIFI module, wherein in order to realize the data forwarding of the PS, the mobile phone needs Install WIFI Router (route) Q. In order to implement the voice call function, both the mobile terminal and the digital terminal need to install a client that supports voice calls, which is identified by a Voice Service. The Voice Service supports peer-to-peer access, so the WIFI path between the two is only a data pipe for the Voice Service, which is identified by the WIFI Tunnel. For digital terminals, if WIFI is supported then the corresponding PS data and PS control are managed by the corresponding service. For the entire system, the Voice Service completes the control of the voice input and output devices (mobile phones or digital terminals) on the terminal, the encoding and decoding of voices, and the processing of control commands. The voice data of the 3G mobile phone is sent to the voice service client (including the control command) on the WIFI tunnel through the voice service client digital conversion and encoding. The voice service of the peer end starts the voice on the terminal after receiving the control command. Management of input and output devices, and decoding and conversion of received voice data The output is output to the voice output device, and the data received on the local voice input device is converted and encoded, and then sent to the mobile terminal.

Because the two voice service clients are peer-to-peer, the following describes the process of the voice service on the mobile phone in combination with the specific voice process.

For the calling process, see Figure 4. The user starts the Voice Service client on the digital terminal, enters the number or selects the local directory to dial the number. The Voice Service packages the request to the mobile phone through WIFI, and controls the MIC and Speaker resources. After receiving the message, the mobile phone starts the local Voice Service client. , parsing the message, if it is a dialing message, establishing a voice path, then calling the dialing process of the mobile phone to make the calling party call, and transmitting the information in the dialing process back to the Voice Service on the digital terminal, displaying the dialing process to the user, and simultaneously putting the network The prompt tone is played to the user. At this time, if the caller chooses to hang up, the voice service on the mobile phone side will call the hang up process, cancel the caller's dialing, and return the information of the hang up process. The voice service on the digital terminal displays the hang up process to the user. After the hang up, the voice path is released, and the MIC and Speaker resources on the digital terminal are released. If the other party answers, the call is successfully established, and the voice service returns the call setup success message. After receiving the message, the digital terminal displays that the call is successfully established. After the call is entered, the voice service of the voice service transmitted by the voice service on the mobile phone side of the 3G Module is transmitted. Converted into a digital signal, encoded and sent to the Voice Service on the digital terminal side via WIFI, and the Voice Service on the digital terminal side decodes the received data and converts it into an analog signal and outputs it to the Speaker. At the same time, the analog signal input by the user voice on the MIC is converted into a digital signal code and sent to the mobile phone side, and the mobile phone side decodes and then converts to an analog signal output to the 3G Module.

For the called, see Figure 5. After the mobile phone calls, the voice service client is started, and the voice service of the digital terminal is notified that there is an incoming call, and the caller number is transmitted to the digital terminal for display on the interface and the call ring tone is played, prompting the user to have an incoming call. If the user chooses to reject the call, the current service will hang up. After receiving the hang up message, the voice service will call the hang up process, and the process information will be sent back to the digital terminal for display to the user. After the hang up process, the digital terminal will be notified to the call. End to release the corresponding audio device resources. If the user chooses to answer the call, after receiving the answer message, the voice service on the mobile phone side calls the answering process to establish a voice path to enter the call. After entering the call, the voice service on the mobile phone side converts the analog signal of the voice data transmitted from the 3G Module into a digital signal, which is encoded and sent to the Voice Service on the digital terminal side through the WIFI, and the Voice Service on the digital terminal side receives the voice service. After the data is decoded, it is converted to an analog signal and output to the Speaker. At the same time, the analog signal input by the user voice on the MIC is converted into a digital signal code and sent to the mobile phone side, and the mobile phone side decodes and then converts to an analog signal and outputs it to the 3G Module.

In the above application example, the voice transmission on the WIFI router is used to provide a solution for the CS voice call while the digital terminal uses the mobile phone WIFI to share the 3G mobile network, thereby overcoming the traditional application scenario. Or the quality of the service is degraded, resulting in a low degree of user acceptance.
