Abstract

The present invention discloses a method of using a wireless terminal to instantly receive and play back an audio data from a wireless network server without requiring the user to download and save the audio data into the wireless terminal first. When the wireless terminal requests the wireless network server to download an audio data, the wireless network server divides the audio data into a several batches of data according to the request of the wireless network server. The batches of data are sequentially downloaded to a voice download buffer of the wireless terminal, and then sequentially sent to a voice playback buffer of the wireless terminal after each batch of data is decoded. Thus, achieving the function of immediately and continuously play back the audio data online through the wireless terminal.

Claims

1. A method of instantly receiving and playing back audio data from wireless network by wireless terminal, being applied to a wireless terminal, a wireless network server, and a wireless network thereon;

said wireless network server at regular time collecting and producing various voice information and converting and saving the voice information into an audio data readable by said wireless terminal;

said wireless terminal comprising a microprocessor, a voice download buffer, a voice playback buffer, and a voice playback device;

if said wireless terminal receiving a request to download a certain type of audio data from said wireless network server, the method comprising the steps of;

requesting said wireless network server to download said type of audio data through said wireless network;

starting to receive said audio data and downloading said audio data to said voice download buffer;

decoding the downloaded audio data if the quantity of received audio data reaching a predetermined value;

sending the decoded audio data to said voice playback buffer;

enabling said voice playback device to access and play back said audio data from said voice playback buffer, and releasing memory space in said voice playback buffer;

determining whether or not said voice download buffer still having any memory space;

if yes, then continuing to download said audio data to said voice download buffer for decoding;

determining whether or not said voice playback buffer still having any memory space;

if yes, then sending said decoded audio data to said voice playback buffer and using said voice playback device to access and play back said audio data from said voice playback buffer.

2. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said wireless terminal uses said voice playback device to access and play back said audio data from said voice playback buffer, while releasing memory space from said voice playback buffer;

if said microprocessor determines that said voice download buffer no longer has memory space, then said microprocessor continues to determine whether said voice playback buffer still has memory space.

3. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said audio data is downloaded from said voice download buffer and played back;

if said microprocessor determines that said voice download buffer no longer has memory space, then said voice playback device is used to access and play back said audio data from said voice playback buffer such that said voice playback buffer releases memory space.

4. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said wireless terminal requests said wireless network server to download a chosen audio data, and the procedure carried out by said microprocessor of said wireless network server comprising the steps of:

analyzing the content of the download requested by said wireless terminal;

checking if the content of the requested download matching the audio data in a user-defined database;

continuously sending said audio data to said wireless terminal;

determining whether the transmission of said audio data is completed;

if yes, then end the procedure.

5. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 4, wherein said microprocessor determines whether the transmission of audio data is completed, and then continues sending said audio data to said wireless terminal, and determines whether the transmission of said audio data is completed again.

6. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said audio data is a song.

7. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said audio data is a news.

8. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said audio data is a weather forecast.

9. The method of instantly receiving and playing back audio data from wireless network by wireless terminal of claim 1, wherein said wireless terminal is a mobile phone.
