METHOD/SYSTEM FOR CONSERVING RESOURCES DURING CONVERSATION OVER WIRELESS NETWORK TRANSPORT MEDIA
First Claim
1. A method of conserving battery power when using a battery-powered communication device to support a conversation over a wireless network transport media, comprising the steps of:
- providing a battery-powered communication device capable of supporting a conversation over a wireless network transport media, the communication device having a high power state (HPS) of operation and a low power state (LPS) of operation wherein battery power required for said LPS is less than battery power required for said HPS;
detecting periods of silence during at least a portion of at least one conversation supported by the communication device;
predicting, using said periods of silence so-detected, future silence periods occurring during at least one of (i) a remainder of said at least one conversation, and (ii) a future conversation supported by the communication device; and
placing the communication device in said LPS during each of said future silence periods so-predicted.

Abstract
A method and system are provided for conserving network resources such as battery power of a battery-powered communication device used to support a conversation over a wireless network transport media. Periods of silence are detected during conversation taking place on a network having controllable resources such as battery power. Using the periods of silence so-detected, future silence periods occurring on the network are then predicted. Allocation of at least a portion of the controllable resources is controlled based on the future silence periods so-predicted.

8. A method of conserving battery power when using a battery-powered communication device to support a conversation over a wireless network transport media, comprising the steps of:
-
providing a battery-powered communication device capable of supporting a conversation over a wireless network transport media, the communication device having a high power state (HPS) of operation and a low power state (LPS) of operation wherein battery power required for said LPS is less than battery power required for said HPS; selecting a threshold audio level; comparing said threshold audio level to an average audio level of a portion of digitized samples associated with a portion of at least one conversation supported by the communication device, wherein periods of silence are indicated each time said average audio level is less than said threshold audio level; generating an empirical cumulative distribution function (ECDF) using said periods of silence so-indicated during said step of comparing; generating a computed training silence length of time α
using said ECDF;detecting a current silence period occurring during one of (i) a remainder of said at least one conversation, and (ii) a future conversation supported by the communication device; determining, using said ECDF, a conditional probability that said current silence period will last an additional length of time Δ
beyond said computed training silence length of time α
, wherein a length of a future silence period is defined by (α
+Δ
) when said conditional probability is greater than or equal to a threshold probability β
; andplacing the communication device in said LPS during said future silence period so-defined during said step of determining. - View Dependent Claims (9, 10, 11, 12)
