Optimization of handover algorithms in 3GPP long term evolution system
Handover in LTE is purely hard handover. The use of break-before-connect handovers reduces the complexity of the LTE network architecture. However, the hard handover may result in data being lost. A Handover algorithm is needed for making handover decision. This decision may vary over time,...

| Summary: | Handover in LTE is purely hard handover. The use
of break-before-connect handovers reduces the
complexity of the LTE network architecture. However,
the hard handover may result in data being lost. A
Handover algorithm is needed for making handover
decision. This decision may vary over time, depending
on user’s mobility. Many handover algorithms have
been proposed. In this work, we optimized three well
known handover algorithms in the LTE system.
Simulation results show that this optimization
outperforms non-optimized algorithms by minimizing
the average number of handovers per UE per second
while maximizing average system throughput. |
