Abstract
Ring-back content is provided to a mobile video caller willing to call a recipient in a process in which: the ring-back content is stored, a first communication leg is established between an intermediate network element and the mobile video caller, a second communication leg is established between the intermediate network element and the recipient, and the delivery of the ring-back content to the mobile video caller is started between the initiating of the mobile video call and answering to the call by the recipient. The delivery of the ring-back content may be lead by an early connect message to delay charging. On establishing the second communication leg, no connect message is passed to the caller, but the charging of the mobile video call is started.
