Abstract: Systems and methods for estimating inter-frequency measurements used for radio network functions are disclosed. The systems and methods described allow systems to evaluate the quality of a second frequency by using offset adjusted measurements on a first frequency. By using the described methods, system capacity is increased by providing a "low cost" measurement mechanism for support of handover that substantially balance the load between two or more frequency bands. By using the proposed method, handover can be performed more frequently and the interference within each frequency band can therefore be kept at a more optimal level.

BY USING THE DESCRIBED METHODS, SYSTEM CAPACITY IS INCREASED BY PROVIDING A "LOW COST" MEASUREMENT MECHANISM FOR SUPPORT OF HANDOVER THAT SUBSTANTIALLY BALANCES THE LOAD BETWEEN TWO OR MORE FREQUENCY BANDS. BY USING THE PROPOSED METHOD, HANDOVER CAN BE PERFORMED MORE FREQUENTLY AND THE INTERFERENCE WITHIN EACH FREQUENCY BAND CAN THEREFORE BE KEPT AT A MORE OPTIMAL LEVEL.

Abstract: A method, controller and system for controlling handoffs in radio communication systems using a softzone concept are described. Soft handoff i s permitted between members of a particular softzone, but not between members of different softzones. Hard handoff is permitted between members of different softzones, but not between members of the same softzone.
