1. A method for effecting a handover of a data flow for a mobile station from a first wireless access point to a second wireless access point, the method comprising:

  • detecting, by a processor, indicia of a change in wireless connectivity of the mobile station with respect to the first wireless access point and the second wireless access point, wherein the first wireless access point and the second wireless access point share a common subnet and wherein the change in wireless connectivity is associated with a handover of the data flow for the mobile station to the second wireless access point from the first wireless access point;

    establishing a temporary data tunnel between the first and second wireless access point; and

    automatically establishing a path for the data flow for the mobile station between the second wireless access point and a network element that is hierarchically differentiated from the second wireless access point, wherein automatically establishing comprises, at least in part, automatically sending a registration request from the second wireless access point to the network element other than in response to a specific request from the mobile station to send the registration request, wherein automatically sending the registration request from the second wireless access point to the network element comprises automatically sending, prior to completion of the change in wireless connectivity, the registration request from the second wireless access point to the network element in response to a specific message having been received by the second wireless access point as transmitted by the first wireless access point.
