1. A method of operating a wireless communication network to handover a User Equipment (UE), the method comprising:
a source access node wirelessly delivering a wireless data service, determining a source Quality-of-Service (QOS) for the delivery of the wireless data service from the source access node, and indicating the source QoS to a handover controller;
the handover controller receiving the source QOS;
the handover controller receiving a target QoS from a target access node that wirelessly delivers the wireless data service, determines the target QoS for the delivery of the wireless data service from target access node, and indicates the target QoS to the handover controller;
the handover controller determining a QoS offset based on a QoS difference between the source QoS and the target QoS and indicating the QoS offset to the source access node;
the source access node receiving the QoS offset for the target access node; and
the source access node receiving a source signal strength metric for the source access node and a target signal strength metric for the target access node from the UE, and in response, selecting the target access node for the handover based on the QoS offset and a signal strength difference between the source signal strength metric and the target signal strength metric and signaling the UE and the target access node to handover the UE to the target access node.
