thanks chefo for replaying.
i thinks the measurement which define the SDCCH are call model(measured holding time for events using SDCCH) & moreover SDCCH/TCH load ratio, allowed GoS for (SDCCH,TCH) and effect of PCH capacity.
But kindely i need to know about HO load & is it have any effect on SDCCH dimentioning and call model.
Also how half rate is implement in cell (fixed OR dynamic by SACCH)and which is better.
Best Regards.
