Abstract
A method of performing a handover as shown in FIGS. 2-3 for a mobile station in a multicellular environment including the steps of determining to handover from one of the plurality of microcells to the macrocell, performing handover from the one of the plurality of microcells to the macrocell; and sending a false neighbor list to the mobile station.
Claims5
A method of performing a handover of a mobile station in a multicellular environment containing at least one macrocell and a plurality of microcells at least partially disposed in the at least one macrocell, the at least one macrocell being in a first layer, the plurality of microcells disposed in a second layer and the handover of the mobile station being between the first and second layers of the multicellular environment, the method comprising the steps of:
- sending to the mobile station a neighbor list identifying cells associated with a layer to which the mobile station has been handed over, said neighbor list excluding neighbor cells belonging to a non-preferred layer, said neighbor list comprising different cells depending an which layer the mobile station is handing over to.
The method of performing handover according to any preceding claim, wherein a signal strength received at a mobile station when served in a microcell is relatievly stronger than a signal strength received at the same mobile station if alternatively served by the macrocell.
