Dynamic admission control for media gateways

A Method for a Mobile Switching Centre Server in connection to a backbone, comprising the steps of:

• receiving a call set-up;
• detecting 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
• providing an indication to said Media Gateway that a higher packet loss or higher jitter is acceptable.

A Media Gateway comprising:

• means for connecting to a backbone,
• said means for connecting are further adapted to receive a call,
• processing means adapted to measure a packet loss,
• said processing means are further adapted to notice an indication that a higher packet loss or a higher jitter is acceptable, and
• said processing means are further adapted to decide based on said measured packet loss or jitter and said noticed indication whether said call is admitted to be routed via said backbone even though the packet loss or jitter is above a predefined threshold.
