Wireless communication management and handoffs
A first wireless access point notifies a handoff management resource that a second wireless access point is a potential handoff candidate. Subsequent to authentication of the second wireless access point as being a valid handoff candidate, the handoff management resource notifies a mobile communication device that the second wireless access point is a valid handoff option to receive a communication session from the first wireless access point. To perform a handoff, the mobile communication device initiates termination of a wireless communication link with the first wireless access point and communicates with the second wireless access point to establish a new wireless communication link. In furtherance of providing uninterrupted network access, the handoff management resource conveys communication settings information associated with the handed off communication session to the second wireless access point for use over the new wireless communication link.
