Method and apparatus for improving measurement accuracy for voice-over-packet bearer network interface
First Claim
Patent Images
1. A method of disconnecting a call between a first endpoint and the second endpoint through a packet network, the method comprising:
- transmitting a disconnect message and a first last packet indicator from the first endpoint to the second endpoint;
detecting the last packet indicator by the second endpoint;
transmitting an acknowledgement message and a second last packet indicator from the second endpoint to the first endpoint in response to the first last packet indicator; and
, closing an input port at the first endpoint in response to the second last packet indicator.

Abstract
A system is provided for improving measurement accuracy for voice-over-packet bearer network interfaces. The presently described embodiments address performance measure inaccuracies that occur during the disconnect sequence of an internet protocol bearer network logical connection. This technique accomplishes this task by generating and transmitting a last packet indicator to ensure that the endpoints of the path are synchronized.
