In this paper, we propose a measurement report mechanism based on the technology of LTE (Long Term Evolution Network). According to different report conditions, reports can be classified into two types:
Event-Triggered Reports and Periodical Reports. The timing to trigger reports is important. Short report timing results in many unnecessary reports and thus a waste of power. On the other hand, a long report timing yields faulty handover decision and thus may cause a long handover delay. To optimize the system performance including the handover delay and power consumption, we propose an improved measurement report mechanism based on the report type. The mechanism adjusts the event trigger timings and periodical report timings by determining user’s mobility state the major components in this mechanism include Signal Monitor and Timer Estimator. Signal Monitor determines the UE’s mobility state, while Timer Estimator can adjust the timer to adapt the change of different timers’ settings. In brief, this paper proposes an algorithm to measure the UE’s mobility, and adjusts the timer’s parameters according to different mobility state to decrease the handover latency and save power.
