LTE Optimization Principle and Method

The optimization of long‐term evolution (LTE) network mainly refers to the pre‐optimization and the continuous optimization before and after the network launched. Network optimization results and the level of network optimization work, directly related to the future performance of the network stability and capacity. When doing optimization, the following performance must be considered. These are coverage, interference, mobility, capacity, and quality. LTE optimization can be divided into two steps, one is radio access network (RAN) pre‐launch optimization, the other is post launch optimization. RAN pre‐launch optimization for LTE assists in the evaluation and tuning of the RAN in order to ensure that the performance and coverage of the RAN is maximized prior to commercial launch. Upon completion of the pre‐launch optimization phase, the acceptance phase will be performed. The post‐launch optimization is carried out on counter level, parameter level, cell level, and terrain/area level.
