Abstract

A cellular communications network includes a plurality of cells (112) whose base stations (114) have smart antenna capabilities. In connection with a potential mobile station (116) hand-off, the smart antenna capable base stations for the hand-off candidate cells report (228) not only on measured traffic channel verification signal strength, but also on measured direction of arrival azimuth orientation angle and/or identity of a particular one of the separate narrow beams which would be needed to serve that mobile station after hand-off. A particular one of the candidate cells is then selected (232) as the target cell for hand-off, and instructions (234, 236) concerning implementation of the hand-off are provided to that target cell. These hand-off implementation instructions include the direction/beam information previously supplied by that target cell. The particular one of the beams specified by the received direction/beam information is then activated (238) in the target cell and a hand-off of the mobile station to that cell is ordered (240).
