CA 2707474

A method and communication device for gracefully extending the range and/or capacity of voice communication systems is disclosed. The method and communication device involve the persistent storage of voice media on the communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, voice media is transmitted and received by the communication device at the available usable bit rate on the network. Although latency may be introduced, the persistent storage of both transmitted and received media of a conversation provides the ability to extend the useful range of wireless networks beyond what is required for live conversations. In addition, the capacity and robustness in not being affected by external interferences for both wired and wireless communications is improved.

L'invention porte sur un procédé et sur un dispositif de communication pour l'extension progressive de la portée et/ou de la capacité de systèmes de communication vocale. Le procédé et le dispositif de communication entraînent le stockage persistant de contenu vocal sur le dispositif de communication. Lorsque le débit binaire utilisable sur le réseau est médiocre et inférieur à celui qui est nécessaire pour conduire une conversation en direct, un contenu vocal est transmis et reçu par le dispositif de communication au débit binaire utilisable disponible sur le réseau. Bien qu'une latence puisse être introduite, le stockage persistant du contenu d'une conversation à la fois transmis et reçu fournit l'aptitude à étendre la portée utile de réseaux sans fil au-delà de ce qui est requis pour des conversations en direct. De plus, la capacité et la robustesse sont améliorées de par le fait que des interférences externes n'ont pas d'incidence sur les communications à la fois câblées et sans fil.
