For example, in a mobile-to-mobile call, a first user's uplink media may be re-compressed while waiting for the media to return from a call server or a first user's uplink media may trigger an eNB/RAN element to prepare a second user RRC/grant just-in-time deliver media to the second user, upon a response from the call server. A method may comprise receiving audio/video on the uplink from a first mobile. The audio/video/media content may be extracted when it is received on the uplink from the first mobile, and may then be re-compressed/customized for delivery on the downlink to the second mobile. When the original content is received back from the server for delivery to the second mobile, the already re-compressed/customized version of the content may be transmitted down to the second mobile.
