  • Seamless handoff across heterogeneous access networks using a handoff controller in a service control point
    Patent number: 8442005
    Abstract: 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.
    Type: Grant

  • System and method for adaptive seamless mobility of multimedia communication sessions
    Publication number: 20070218902
    Abstract: A network-based Adaptive Seamless Mobility Controller provides a view not only of the capabilities of the specific device in use by the user but also the capabilities of the access network serving each user involved in the session. When the user equipment identifies the opportunity to enhance the communication through adaption of the session to include, for example, a video connection in addition to a voice connection, by utilizing a different access network and corresponding device, the network-based Adaptive Seamless Mobility Controller determines the end-to-end capabilities required for the session and coordinates the adaptation of the session characteristics in addition to providing seamless handover across domains.
