hi every body
in my netowrk we use co_sitig band 900+1800 ,not dual band
but we have a problem in our netowrk
we use gsm band 900 just for coverage outer zone
and gsm 1800 for capacity in inner zone ,but about our problem ,i check every day our network STS and seen which just band 900 has more traffice congestion and 1800 hadnt any congestion like below
cell900 have 95.3% trafice congestion
and cell1800 just have 2% ok
how can i share our load to make a balance between these cell just except any feature like Hierarchical Cell Structures HCS
BR
