Abstract: Methods and apparatus for supporting a data center relocation with regard to an access point are described. A primary gateway connection is established between the access point and a primary gateway in a first data center, and a secondary gateway connection is established between the access point and a secondary gateway in a second data center. A path switch request is sent via the secondary gateway connection. A DNS server sends an IP address corresponding to the second data center. The data center for the access point is switched from the first data center to the second data center. In some embodiments, the transition from the first data center to the second data center is in response to a detected communications failure. In other embodiments, the transition from the first data center to the second data center is due to scheduled maintenance.

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.

Abstract: A paging signal transmitting method includes a step of allowing each of mobile stations (UE) to receive security data from a network node (1) via a channel specified by a paging signal, a step of allowing each mobile station (UE) to calculate a third set of security information by using an open first set of security information and a second set of security information managed by each mobile station, a step of allowing each mobile station (UE) to compare the third set of security information with a fourth set of security information included in the received security data to verify the validity of the paging signal, and a step of allowing each mobile station (UE) to output a signal corresponding to the paging signal when the validity of the paging signal is verified.

Abstract: One embodiment of the present invention provides a system that communicates cryptographic data through multiple network layers. During operation, the system receives the cryptographic data and divides the cryptographic data into multiple pieces. The system then encapsulates different pieces of the cryptographic data into fields associated with different network layers in a data packet, whereby an item of cryptographic data that is too large to be communicated in a single field can be communicated through multiple fields associated with different network layers.
