Self-optimization in LTE: An Approach to Reduce Call Drops in Mobile Network

Unwanted terminations of an on-going wireless conversation become the biggest issue of the whole world. Call drop degrades the voice call quality and impacted the quality of service of the network. Researchers, industries, and telecom- vendors are bothered to improve the call quality in existing telecom infrastructure and already proposed many valuable solutions which have own pros and cons but still there is no optimized reliable solution to reduce call drop has been deployed till now. This research paper focuses on some background reasons for call drop in existing wireless infrastructure and proposed the self-optimization concept to handle the overall network issue automatically in perspective of call drops minimization in mobile networks. This Research paper proposed some robust functionality of self-optimizing network such as automatic neighbor list optimization, mobility load balancing optimization and handover optimization approach used to improve voice call quality and make a self-automated mobile network that would be fruitful to reduce call drop rate.
