CA 2661031

Conveying Push- To-TaIk and Push-To-Signal (PTT/PTS) information over an IP network through signaling bits defined in and propagated with the Real -Time Protocol (RTP) stream allows the PTT/PTS information to remain synchronized with the voice packets of the stream. The maintenance of synchronization of PTT/PTS signals and voice packets eliminates problems arising from failure of synchronization between the two classes of packets, notably the "shoot/don't shoot" problem. The signaling bits employed were formerly used to convey legacy network information, but are no longer in active use in the Voice-over-IP (VoIP) realm, since VoIP provides alternative pathways for their information.

L'invention concerne le transport d'informations Presser-Pour-Parler et Presser-Pour-Signaler (PTT/PTS) sur un réseau IP par l'intermédiaire de bits de signalisation définis dans le flux de protocole en temps réel (RTP), et propagés avec le flux, qui permet aux informations PTT/PTS de rester synchronisées avec les paquets vocaux du flux. Le maintien de la synchronisation de signaux PTT/PTS et de paquets vocaux élimine les problèmes provenant de l'échec de synchronisation entre les deux classes de paquets, notamment le problème 'envoyer/ne pas envoyer'. Les bits de signalisation employés ont été utilisés antérieurement pour transporter des informations de réseau hérité, mais ne sont plus en utilisation active dans la partition Voix-Sur-Internet (VoIP), étant donné que VoIP fournit des trajets alternatifs pour leur information.
