Abstract
In a method for dynamically setting a content rate of a multimedia session for a client in a network, a proxy server receives a channel condition feedback message from a network controller and determines whether a receiver report message has been received from the client since a most recent previous channel condition feedback message. The channel condition feedback message includes current channel condition information for the network. The proxy server sends one of an extended feedback report message and a short feedback report message to a media server based on the determining step. The short feedback report message includes at least a maximum transmission rate parameter for the multimedia session. The extended feedback report message includes at least information contained in the receiver report message. The extended feedback report message may, in addition, include the maximum transmission rate parameter for the multimedia session.
