A method and apparatus for handover in a wireless communication device
between wireless domains is described. In one example, a signal employing
a short-range wireless protocol is detected at the wireless communication
device. For example, the short-range wireless protocol may be a
near-field communication (NFC) protocol, a radio frequency identification
(RFID) protocol, an optical protocol, a BLUETOOTH protocol, and the like
known in the art. A handover is requested from the first wireless domain
to the second wireless domain in response to the detected signal. In one
example, the signal may be broadcast by an access control system to a
building and may be configured to control access to the building. In this
manner, precise delineation of the handover boundary between wireless
domains is provided.
