Abstract:
Service continuity when a user equipment (UE) employing local breakout mechanisms at a femto access point (FAP) for a communication session and moves out of the femto coverage area is disclosed. In particular, a network change detection component can be employed to detect when the UE, attached to the FAP, changes its connection from the femto network to the macro network. Further, an active communication session can exist between the UE and a device/service/application on a local Area network (LAN) connected to a FAP, and/or the Internet, which utilizes local breakout at the FAP. When the UE moves out of the femto network, a context management component can be employed to seamlessly resume the communication session, via the macro network.
