Discontinuous reception of bursts for voice calls
First Claim
Patent Images
1. A method of receiving signals during an active call, the method comprising:
- detecting an end of received speech during an active voice call;
disabling a receiver for selected receive bursts during the active call responsive to detecting the end of the received speech;
detecting a start of received speech during the active call by;
enabling the receiver for a first receive burst to receive signals;
decoding the received signals received in the first burst to produce decoded signals; and
determining whether the decoded signals include an identifier transmitted by a remote party'"'"'s device to indicate the start of speech signals; and
switching the receiver on or off for subsequent receive bursts to receive the speech signals or not based on whether the identifier is present in the decoded signals.

Abstract
A mobile terminal capable of operating in a Discontinuous Transmission mode during an active voice call with a remote party is also capable of operating in a Discontinuous Reception mode during the same active voice call. Particularly, a receiving mobile terminal monitors when the remote party stops transmitting speech during the active voice call. If there are no speech signals to receive, the mobile terminal switches it'"'"'s receiver “off” for selected receive time slots to save battery power.

10. A wireless communication device comprising:
-
a receiver configured to receive speech signals in a normal receive mode during an active voice call; and a controller configured to; detect an end of the received speech signals during the active voice call; switch the receiver to operate in a discontinuous reception of bursts mode during the active call responsive to detecting the end of the received speech signals; detect a start of received speech signals during the active call by; enabling the receiver for a first receive burst to receive signals; decoding the received signals received in the first burst to produce decoded signals; and determining whether the decoded signals include an identifier transmitted by a remote party'"'"'s device to indicate the start of speech signals; and switch the receiver on or off for subsequent receive bursts based on whether the identifier is present in the decoded signals. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of transmitting speech signals having control information during an active voice call, the method comprising:
-
generating an indicator indicating an end of speech blocks being transmitted to a remote device during an active voice call; and transmitting the indicator in a first radio block to switch the remote device to operate in a discontinuous reception of bursts mode of operation while engaged in the active voice call; generating an identifier indicating a start of the speech blocks for transmission to the remote device; and interleaving the identifier with encoded speech into a first frame of a second radio block to indicate the start of the speech blocks to the remote party. - View Dependent Claims (19, 20, 21)

22. A wireless communication device comprising:
-
a controller configured to; generate an indicator indicating an end of speech blocks being transmitted to a remote device during an active voice call; generate an identifier indicating a start of the speech blocks for transmission to the remote device; and interleave the identifier with encoded speech into a first frame of a second radio block; and a transmitter configured to; transmit the indicator in a first radio block to switch the remote device to operate in a discontinuous reception of bursts mode of operation while engaged in the active voice call; and transmit the identifier interleaved with the encoded speech in the first frame of the second radio block to indicate the start of the speech blocks to the remote party. - View Dependent Claims (23, 24, 25)
