Disclosed is a method and system for accounting for network signaling values in handover decisions. A serving base station may receive a message from a served user equipment device (UE) indicating that handover condition is met for handing over to one or more target base stations. The serving base station can determine a respective network signaling value being used by each target base station, and thereby determine how much uplink attenuation the UE would be directed to apply for each potential handover. The serving base station can also determine its downlink power and that the target base stations as measured by the UE. The serving base station can then make a handover decision taking account of a change in uplink attenuation for each potential handover.
