Patent

CA 2608721

In a telecommunications network in which a mobile handset is capable of communicating in both an IP domain and a non-IP domain, the handoff of an existing communications session between the mobile handset and a fixed user is facilitated by a handoff controller implemented in a service control point. The handoff controller implements different handoff methods depending on the status of the fixed user and the transition of the mobile user. Additionally 802.21 Media Independent Handover Function in conjunction with SIP is used to facilitate handover between IP and Non-IP points in the system.

Dans un réseau de télécommunications dans lequel un combiné mobile est capable de communiquer à la fois dans le domaine IP et dans le domaine non IP, le transfert d'une session de communicationexistante entre le combiné mobile et un utilisateur fixe est facilité par un contrôleur de transfert mis en oeuvre dans un point de commande de services. Ce contrôleur de transfert met en oeuvre différents procédés de transfert selon l'état de l'utilisateur fixe et la transition de l'utilisateur mobile. De plus, une fonction de transfert indépendante des supports 802.21 conjointement avec SIP est utilisée pour faciliter le transfert entre des points IP et non IP dans le système.
