Method and apparatus for handover in a wireless communication device between wireless domains
First Claim
1. A method of handover between a first wireless domain and a second wireless domain, comprising:
- detecting a signal employing a short-range wireless protocol at a wireless device, the signal including a signature identifying at least one of the first or second wireless domains;
determining a direction of handover between the first wireless domain and the second wireless domain based on the signature in the signal; and
requesting, in response to the signal, a handover between the first wireless domain and the second wireless domain in the direction as determined.

Abstract
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.
