摘要

A method and apparatus are described including determining address using an access point address and a multicast group address, transmitting a recovery request message to a recovery server to request recovery data using the address and receiving the recovery data from the recovery server. Also described are a method and apparatus including receiving a registration message, transmitting a reply to the registration message, receiving a recovery request message, transmitting recovery data responsive to the recovery request message and transmitting a message to a recovery multicast group to determine status of the recovery multicast group.
