Abstract
A method and a communication network node for satisfying detection miss probability and false detection probability requirements in a random access channel used by mobile stations (MS) for accessing a communication network system comprising radio base stations (BS) each serving at least one cell (19). The method includes optimizing a random access channel, wherein the method performs estimating detection miss probability (P m) in said cell, tuning random access parameters such that said estimated detection miss probability satisfies predetermined requirements, estimating a false detection probability (P f) in said communication cell (19), tuning said random access parameters such that said estimated false detection probability satisfies predetermined requirements, and tuning said random access parameters such that an extensive interference caused by mobile stations attempting random access in said communication cell is avoided.
