Synchronization of signaling messages and multimedia content loading

Abstract

A method synchronizes signaling messages and multimedia content loading at a callee terminal. A first signaling message transmitted from a caller terminal to initiate a multimedia session establishment is processed to detect, in the first signaling message, information indicating that the multimedia content should be presented in synchronization with a second signaling message necessary to session establishment. The multimedia content is downloaded and presented in accordance with the information indicating that the multimedia content should be presented in synchronization with said second signaling message necessary to session establishment. The second signaling message necessary to session establishment is delayed until after the step of downloading and presenting the multimedia content in accordance with the information indicating that the multimedia content should be presented in synchronization with the second signaling message is completed.

1 . A method of synchronizing signaling messages and multimedia content loading, comprising: 
 at a callee terminal, processing a first signaling message transmitted from a caller terminal to initiate a multimedia session establishment by detecting, in said first signaling message, information indicating that said multimedia content should be presented in synchronization with a second signaling message necessary to session establishment;    downloading and presenting said multimedia content in accordance with said information indicating that said multimedia content should be presented in synchronization with said second signaling message; and    delaying said second signaling message necessary to session establishment until after completing said step of downloading and presenting said multimedia content in accordance with said information indicating that said multimedia content should be presented in synchronization with said second signaling message.    
     
     
         2 . A method in accordance with  claim 1  wherein said first signaling message and said second signaling message respectively comprise a first SIP message and a second SIP message.  
     
     
         3 . A method in accordance with  claim 2  wherein: 
 the first SIP message is a SIP INVITE message.
