  • Method for handoff during connected mode of a multimode mobile station in mixed deployment
    Patent number: 9173138
    Abstract: Methods for handoff of a multimode mobile station (MS). The MS, in connected mode, moves from a cell of a legacy base station to a cell of an ABS and scans base stations from a list of neighboring base stations, wherein at least the ABS is listed as another legacy base station in the list of neighboring base stations. The MS performs the handoff to connect to a legacy zone of the ABS. Further, the multimode MS switching from the legacy zone of the ABS to a advanced zone of the ABS based on a Zone Switch request or command is triggered by either the multimode MS or the ABS. The Zone Switch request is triggered after detecting capabilities of either the multimode MS or the ABS that they support advanced zone. The capabilities are detected by using MAC versions of the multimode MS and the ABS or an indicator for the advanced zone.
