A Lightly-loaded cell initiated Load Balancing in LTE self-optimizing networks

Deploy and maintenance of Future LTE RAN will be more complex, time consuming, and expensive. In order to meet the requirements of operators and users, self-organization networks is introduced. As one of the most important self-optimization issues, Mobility Load Balancing ( MLB ) has received much attention until now. In this paper, we present a novel method to achieve MLB for LTE RAN, namely, LCIMM (Lightly-loaded Cell Initiated MLB Method). The lightly loaded cell can initiate and trigger handover behaviors of users by automatically adjusting the cell offsets based on cell load measurements. The LCIMM is subject to a system-level simulation which witnesses an improvement in load distribution index,number of unsatisfied users and handover times.
