Handover control in radio communication system
First Claim
1. A handover control method in a radio communication system, the method comprising:
- measuring, at a mobile station, signal strength of transmissions received from one or more base stations;
determining, at the one or more base stations, radio resource management related information regarding the base station, sending by the one or more base stations, the information to the mobile station;
combining, at the mobile station, the information received from each base station with the signal strength of each base station;
sending, by the mobile station, the information as combined information to a base station;
receiving, at the base station, the information; and
controlling handover decisions regarding the mobile station based on the received information.

Abstract
A handover control method and a radio communication system comprising a mobile station and one or more base stations are provided. The mobile station receives transmissions from one or more base stations, and measures the signal strength of each received base station transmission. The base stations determine radio resource management related information regarding the base station and send the determined information to a mobile station. The mobile station combines information received from each base station with the measured signal strength of each base station, and sends the combined information to a base station. The base station receiving the information controls handover decisions regarding the mobile station on the basis of the received information.

11. A radio communication system, comprising:
-
a mobile station; and
one or more base stations, wherein the mobile station is configured to receive transmissions from one or more base stations and measure a signal strength of each received base station transmission, wherein the base stations are configured to determine the base stations'"'"' own radio resource management related information and to send the information to the mobile station, wherein the mobile station is further configured to combine information received from each base station with a measured signal strength of each base station, and to send combined information to a handover base station, and wherein the handover base station receiving the combined information is configured to control handover decisions regarding the mobile station based on the combined information.
