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.

Abstract: An intelligent mobile radio unit is served by one of a network of macrocells and microcells. The unit is arranged to monitor, for example, the signal strength or bit error ratio of signals transmitted from each of a set of candidate base stations of cells surrounding the serving base station based on the assessment of a running average of the rise/fall in signal quality, the unit is arranged to determine from a look-up table of stored templates of conditions for handover whether a handover between base stations and between macro- and microcells is appropriate.
