Method and apparatus for transferring non-speech data in voice channel
First Claim
1. A method for a mobile terminal in mobile communication systems to transfer non-speech data over voice channel, comprising steps of:
- (a) detecting whether the speech burst sent to another mobile terminal is over;
(b) checking whether there is non-speech data to be sent to said another mobile terminal if detecting that the speech burst is over;
(c) sending at least one non-speech data to said another mobile terminal via voice channel if there is non-speech data to be sent.

Abstract
A method is proposed for a mobile terminal in mobile communication systems to transfer non-speech data in voice channel, comprising steps of: encapsulating the non-speech data to be sent to another mobile terminal into IBD frames; storing said IBD frames in a buffer; detecting whether a speech burst sent to said another mobile terminal is over; checking whether there is non-speech data to be sent to said another mobile terminal if detecting that said speech burst is over; sending at least one non-speech data to said another mobile terminal via voice channel if there is non-speech data to be sent. By modifying the SID frame and silence speech frame, this method realizes transmission of non-speech via voice channel rather than via dedicated data channel, so as to save radio resources of the system.

13. A method for a mobile terminal to transfer non-speech data in voice channel, comprising steps of:
-
(i) detecting the received frame from another mobile terminal;
(ii) storing, if the received frame is a IBD (In-Band Data) frame, the IBD frame;
(iii) generating background noise by using the previously received SID frame. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A mobile terminal, comprising:
-
the first detecting unit, for detecting whether a speech burst sent from the mobile terminal to another mobile terminal is over, and checking whether there is non-speech data to be sent to said another mobile terminal when detecting that the speech burst is over;
a sending unit, for sending frames to said another mobile terminal;
a control unit, for controlling said sending unit to send at least one non-speech data frame to said another mobile terminal via voice channel when there is non-speech data to be sent. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
