Abstract:
1. A method for satisfying random access attempt success requirements of a random access channel (RACH) used by a mobile station (MS) for accessing a communication network accessible in a communication cell served by a radio base station (BS), said mobile station (MS) communicating on uplink and downlink channels, the method comprising the steps of: gathering data during a time period, the data including a number of preamble transmission attempts to the base station made by the mobile station in order to perform a successfully executed random access to the base station, estimating quantities, including a false detection probability, related to random access attempt success statistics in said cell based on the gathered data, tuning random access parameters such that said estimated quantities related to random access attempt success statistics satisfy predetermined random access attempt success requirements, and using said false detection probability and requirements on a maximum false detection probability to compute a detection threshold.
