Coordinating Handover Parameter Optimization and Load Balancing in LTE Self-Optimizing Networks
In this paper, the authors present simulation results of a self-optimizing network in a Long-Term-Evolution (LTE) mobile communication system that uses two optimizing algorithms at the same time: Load Balancing (LB) and Handover Parameter Optimization (HPO). Based on previous work, they extend the optimization by a combined use case. They present the interactions of the two SON algorithms and show an example of a coordination system. The coordination system for self optimization observes system performance and controls the SON algorithms. As both SON algorithms deal with the handover decision itself, not only interactions, but also conflicts in the observation and control of the system are to be expected and are observed.
