Method and apparatus to control cell substitution
First Claim
1. A method of operating a communication system having a plurality of packet network routes and a plurality of packet substitution methods, the method comprising:
- receiving a set-up signaling message for a call into a signaling processor;
in the signaling processor, processing the set-up signaling message to select one of the packet network routes for the call;
in the signaling processor, processing the set-up signaling message to select one of the packet substitution methods for the call;
in the signaling processor, generating a control message for the call indicating the selected packet network route and the selected packet substitution method;
transferring the control message for the call from the signaling processor;
in a routing system, receiving the control message for the call;
in the routing system, receiving user communications for the call, and in response to the control message, transferring the user communications using the selected packet network route; and
in the routing system, in response to the control message, implementing the selected packet substitution method to handle lost packets for the call.

Abstract
A communication system determines a cell substitution method based on information for a call to improve call quality. The communication system receives information for the call. The communication system then determines the cell substitution method based on the information. The communication system generates an instruction to use the cell substitution method for the call. The communication system advantageously uses an optimal cell substitution method for each different type of call. The communication system uses the optimal cell substitution method when a cell is lost or misinserted.
