HANDOVER IN A CELLULAR COMMUNICATION SYSTEM
First Claim
1. A cellular communication system including a number of base stations supporting macro cells and with unique cell scrambling codes within a region and a number of access points supporting underlay cells and with shared cell scrambling codes within the region, the cellular communication system comprising;
- at least one access point or base station comprising transmit means for transmitting an indication of at least a first shared scrambling code to a remote station, the shared first scrambling code being shared by a plurality of access points;
the remote station being arranged to receive the indication of the first shared scrambling code and to determine if a first signal using the first shared scrambling code is received; and
handover means for, if the first signal is detected, handing the remote station over to at least a first access point of the plurality of access points sharing the first shared scrambling code.

Abstract
A cellular communication system includes base stations supporting macro cells and with unique cell scrambling codes within a region. The system further includes access points supporting underlay cells and with shared cell scrambling codes within the region. One or more of the access points or base stations comprise transmit means for transmitting an indication of at least a first shared scrambling code to a remote station. The shared scrambling code is shared by a plurality of access points. The remote station is arranged to receive the first shared scrambling code and to determine if a first signal using the first shared scrambling code is received. If the first signal is detected, a handover controller initiates a handover of the remote station to at least a first access point of the plurality of access points sharing the first shared scrambling code.

20. A method of operation for a cellular communication system including a number of base stations supporting macro cells and with unique cell scrambling codes within a region and a number of access points supporting underlay cells and with shared cell scrambling codes within the region, the method comprising the steps of;
-
at least one access point or base station transmitting an indication of at least a first shared scrambling code to a remote station, the first shared scrambling code being shared by a plurality of access points; the remote station receiving the indication of the first shared scrambling code; the remote station determining if a first signal using the first shared scrambling code is received; and if the first signal is detected, handing the remote station over to at least a first access point of the plurality of access points sharing the first shared scrambling code.
