Method and system for network-directed media buffer-size setting based on device features

A method and system for setting buffer size on a wireless communication device (WCD). A network entity receives a streaming-media-session initiation message from the WCD. The network entity determines a WCD buffer size, based at least on one or more features of the WCD, and sends to the WCD a directive to use the determined WCD buffer size. In one example, the network entity may determine the WCD buffer size based at least on media player version in use on the WCD and make and model of the WCD.
