Abstract
Methods and systems for a wireless communication device (WCD) to change a media session codec prior to handoff to a new wireless coverage area are presented. In particular, a WCD is served by a first wireless coverage area of a RAN, and is conducting a media session using a first codec. The WCD detects that it is about to be handed off to a second wireless coverage area, and transmits a request to a server to determine the capacity available to the WCD via the second wireless coverage area. If this capacity is less than the capacity request by the first codec, the WCD proactively renegotiates the media session to use a second codec that requires less capacity. The server may take various factors into account when responding to the WCD's query, including the sector loading of the second wireless coverage area, available capacity at a backhaul link between the RAN and a network, and/or a profile of the WCD.
