Abstract
A method is implemented by a network device in a cellular communication network. The method to improve handover processing by a source evolved universal terrestrial radio access network (E-UTRAN) node B (eNodeB) where the source eNodeB forwards traffic destined for a user equipment (UE) that is transferring its connection to a target eNodeB to enable mobility within the cellular communication network without anchor points. The method including receiving a handover request from the UE identifying the target eNodeB, sending a handover message to the target eNodeB, determining the UE is unavailable to the source eNodeB, and redirecting traffic for the UE to the target eNodeB.
