摘要： A method for authenticating a mobile node (102) in a communication network (100) is provided. The communication network includes at least one proxy server and a home server. The mobile node and the home server include a shared key. The shared key uniquely associates the mobile node with the home server. The method at the mobile node includes sending (204) a request for an Internet Protocol (IP) address to at least one proxy server. Further, the method includes receiving (206) a nonce in response to the request, from a proxy server of the at least one proxy server. The method also includes deriving (208) a session key, based on the nonce and the shared key. The session key authenticates the mobile node to initiate a secure communication session with the proxy server.

摘要： In a communication system (100) where a wireless relay node (RN) (114) relays data packets between a Node B (112) and a user equipment (UE) (102), the RN receives (608) a data packet from the Node B via a first wireless link (115), conveys (614) the received data packet to the UE via a second wireless link (120), determines (616) whether the UE is likely to handoff, and in response to determining that the UE is likely to handoff, delays conveying (620, 622) an acknowledgment of the data packet to the Node B until an acknowledgment has been received from the UE. In another embodiment, the RN may use a status report (720) to inform the Node B of data packets that have not been transmitted to the UE or that have been transmitted to the UE but for which an acknowledgement has not been received from the UE.
