Title
(EN) WIRELESS HANDOFFS BETWEEN MULTIPLE WIRELESS NETWORKS
(FR) TRANSFERTS SANS FIL ENTRE DES RESEAUX SANS FIL MULTIPLES
Abstract
(EN)
A wireless communications device is disclosed. The wireless communications device is configured to support a call over a cellular network or an IP network to a remote communications device. The wireless communications device is further configured to handoff the call between the cellular network and the IP network. An Interworking Function (IWF) is configured to maintain a call between a wireless communications device and a communications device as the wireless communications device is handed off between a cellular network and an IP network.
(FR)
L'invention concerne un dispositif de communication sans fil. Ce dispositif est configuré pour soutenir un appel sur un réseau cellulaire ou un réseau IP vers un dispositif de communication à distance. Le dispositif de communication sans fil est également configuré pour transférer l'appel entre le réseau cellulaire et le réseau IP. Une fonction d'interfonctionnement (IWF) est configurée pour maintenir un appel entre un dispositif de communication sans fil et un dispositif de communication pendant que le dispositif de communication sans fil est transféré entre un réseau cellulaire et un réseau IP.
