Abstract

This paper analyzes the behavior of a distributed
Mobility Load Balancing (MLB) scheme in a multi-layer 3GPP
(3rd Generation Partnership Project) Long Term Evolution
(LTE) deployment with different User Equipment (UE) densities
in certain network areas covered with pico cells. Target of the
study is to evaluate MLB in terms of efficient pico cell utilization
and macro layer load balancing (LB). The analysis focuses on
video streaming traffic due to specific service characteristics (e.g.
play-out buffer delay/ jitter protection) that might make any
mobility performance degradation transparent to the end user
performance. Results have shown that the proposed MLB scheme
can significantly improve the overall network resources
utilization by eliminating potential load imbalances amongst the
deployment layers and consequently enhance user experience.
However this occurs at the cost of increased Radio Link Failures
(RLF), a fact that might be critical for further applying MLB in
real-time conversational services without additional mobility
optimization and interference management techniques.
