    Abstract: A wireless access point (200), upon determining (101) that a need exists to support a communication need of a mobile station, acquires (102) a first Internet Protocol (IP) address and automatically transmits (103) a gratuitous Address Resolution Protocol message to a local router to thereby cause the latter to correlate the first IP address to a Medium Access Control address for the wireless access point. In a preferred embodiment the wireless access point can also automatically transmit a registration request to a remote network element (such as a Home Agent) that presents this first IP address as a care-of address to use in conjunction with another IP address that serves as a home address for the mobile station.

    Abstract: In the present technique of a communication system (100), an address of a forwarding agent (114) linked to a receiver node (112) is detected to provide a discovered address. The discovered address is then used to establish a direct route with the forwarding agent of the receiver node for subsequent communications between a sender node (104) and the receiver node.

    Abstract: An apparatus and method is described for authentication while exchanging data in a communication system includes deriving (100) an authentication signature from a shared secret, data in an existing data packet, and/or a sender identification. A next step (102) includes appending the authentication signature in an authentication field to the existing data packet. A next step (104) includes sending the data packet with the appended authentication field. A next step (106) includes receiving the data packet by a base station. A next step (108) includes verifying that the authentication field was produced by a sender possessing the shared secret. A next step (110) includes returning an acknowledgement message.
