Dynamic admission control for media gateways

摘要

A Media Gateway, in connection to a backbone, measures a packet loss and/or jitter, receives a call and notices an indication that a higher packet loss and/or jitter is acceptable. The Media Gateway decides, based on said measured packet loss or jitter and said indication, whether the call is admitted to be routed via said backbone even though the packet loss or jitter is above a predefined threshold. A Mobile Switching Centre Server in connection to a backbone, receives a call set-up, detects that a call set-up should be performed by a Media Gateway even if the packet loss or jitter is above a predefined threshold, and provides an indication to the Media Gateway that a higher packet loss or jitter is acceptable.

1. A Method for a Media Gateway in connection to a backbone, comprising the steps of: measuring a packet loss or a jitter associated with said backbone, receiving a call when the measured packet loss exceeds a predefined packet loss threshold or when the measured jitter exceeds a predefined jitter threshold for said backbone; detecting an indication associated with the call, wherein the indication is based on a time period associated with the predefined packet loss threshold or the predefined jitter threshold, and wherein the indication indicates that the measured packet loss exceeding the predefined packet loss threshold or the measured jitter exceeding the predefined jitter threshold is acceptable for the call for said time period; based at least partially on the measured packet loss or the measured jitter and said indication associated with the call, deciding whether said call is admitted to be routed via said backbone; and adjusting the Quality of Service (QoS) level for said call when deciding said call is admitted via said backbone.
