A system for cellular network mobility management based on user equipment measurements includes a host device, cellular communication cells, and a back office. The host device, cellular communication cells and back office execute a cellular network mobility management application (CMMA). The CMMA as initiated by the host device, generates control-plane measurement event based handover suggestions, generates quality-of-service (QoS) measurement based handover suggestions. Then the CMMA, via the cellular communication cells, performs cellular network signal strength monitoring and determines that a measurement configuration (MC) threshold has been achieved. Subsequently, the system performs anomaly detection; and selectively alters timing of cellular network handovers between the host device and the one or more cellular communication cells to reduce a potential for repetitive handovers from a first level to a second level less than the first level while maintaining or improving a cellular network QoS.
