  • System and method for subscriber mobility in a cable network environment
    Patent number: 8902815
    Abstract: A method is provided in one example embodiment and includes creating a service flow with an endpoint over a wireless link coupled to a backhaul; notifying a mobility anchor of a location associated with the endpoint; relaying control packets between the endpoint and an access gateway; and relaying bearer packets between the endpoint and the mobility anchor, where the bearer packets are exchanged with the endpoint over a locally terminated bearer tunnel and the bearer packets are exchanged with the mobility anchor using Proxy Mobile Internet Protocol.
    Type: Grant
