Abstract:
In one aspect, the present invention in one or more embodiments improves mobility management—e.g., handover processing enhancement—by providing/utilizing additional information in combination with CoMP operation, for enhancing the handover procedure. For example, the additional information is used to improve judging the most suitable target cell (14). The additional information can be, for example, angle of arrival or time advance of the UE (20) in handover, RTT, power headroom or signal strength. In at least one embodiment, the information used for handover processing at source and/or target base stations (12-1, 12-2) is enhanced or otherwise made richer by the use of “geometric information” for mobile terminals (20). In one such embodiment, the geometric information used for handover processing associated with a given terminal (20) indicates something about the mobile terminal's position (relative or absolute).
