Abstract

A cellular communications network includes a plurality of cells whose base stations (122) have smart antenna capabilities and conventional sector antenna capabilities. At mobile station (142) call setup, the call is initially set up on a sector antenna supported, looser frequency reuse plan assigned, measurement traffic channel frequency provided by the serving base station. Higher quality direction of arrival angle measurements (210) are then made at the serving base station to identify a particular smart antenna narrow beam which could serve the mobile station. A replacement frequency supported by that narrow beam is then selected (214), and an intra-cell handoff of the call is ordered (216). In the event mobile station location information is needed (e.g., based on the call type or call priority), neighbouring base stations are instructed (304) to make (306) and report (308) on direction of arrival angle measurements towards the mobile station. The reported angles are then processed (310) using triangulation (or other suitable) techniques, in view of known base station geographic location, to determine an approximate location of the mobile station.
