HI
I think in any microcelular environment there is an umbrella cell to improve capacity & to avoid high recurrent handover.
for instance the umbrella have the BCCH carrier so any MS camp on it, so for MS with high velocity the MS TCH allocated from umbrella (available TCH or alloted with perioretization algorithm.and Microcell just connected with bedstrain MS.
The speed threshold may measured by umbrella with TA, or by number of HO /second at microcellular environment.(as vendor tech)
regards.
