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.
