Handover methods and apparatus
Abstract:
Methods and apparatus for supporting handovers which are hidden from a Mobility Management Entity (MME) as well as handovers which are not hidden from the MME are described. A gateway, e.g., a home gateway (HGW), in a communications system acts as a concentration point for a plurality of small cell HeNBs. Two types of handovers, a visible handover and a hidden handover are supported. With a hidden handover, the handover is hidden from the SGW and the MME, thus reducing backhaul control signaling and loading on the SGW and MME. A gateway, e.g., a home gateway (HGW), receives a path switch request message for a user equipment (UE) device from a target access point, e.g., a home eNB (HeNB). In some embodiments the gateway, e.g., the HGW, decides whether a requested handover should be visible or should be hidden, and then performs a handover implementation in accordance with its decision.
