Reply To: SDCCH Blocking & Location update


What counter do operators use to detect blocking problems in SDCCH: blocking rate or congestion rate (%time in congestion?

Do they really want to overdimension SDCCH resources to carry peaks of LU traffic (p.ej. train/bus station, airport) that could be done no matter the delay or even performed in other cells? (note that a high blocking rate, possibly due to repeated LU attempts concentrated in time, does not necessarily mean bad call initiation blocking performance)

Wouldn´t congestion ratio be a better KPI to reflect call initiation problems(ideally uniformly distributed in time)?
