Antenna adaptation to manage the active set to manipulate soft hand-off regions
First Claim
Patent Images
1. A method for managing an active set of radio channels used in soft hand-off processing, the method carried out in a remote unit having an adaptive antenna, the method comprising the steps of:
- determining an initial list of members for the active set by detecting an existence of at least two pilot channel signals in a vicinity of the remote unit;
making a change in an operating state of the adaptive antenna; and
requalifying the active set with the changed adaptive antenna operating state.

Abstract
A method of managing the number of base station engaged in soft hand-off in a mobile communication system. The method involves manipulating a subscriber based directional antenna so as to control the number of base transceiver stations, pilot channels, beacon signals or other signals detected to be used in soft hand-off processing. The adaptive antennas are modified to manage the number of active set members, such as by manipulating direction, beamwidth, or other antenna parameters.
