Multi-layer architecture, Handover, Call blockingprobability
This letter presents a multi-layer cellular architecture
which optimizes the handover call blocking probability
performance of High-Speed Moving Terminals (HSMT)
in a congested urban area. A micro cellular architecture
solution is proposed on lower layer architecture in order
to absorb traffic of Low-Speed Moving Terminals
(LSMT) and traffic of new calls of HSMT. Higher layer
architecture, based on a macro cell umbrella solution, is
proposed to absorb the traffic of handoff calls of HSMT.
The results show, that using the optimum number of
channels in each layer, the handover call blocking
probability of HSMT is optimized with the minimum
effect on the call blocking probability of the rest calls.
