摘要：
The present invention relates to a method and a communication network node for automatically tuning a PRACH configuration parameter in a communication network system comprising radio base stations each serving at least one cell and with which user equipments are communicating on uplink and downlink channels. The PRACH configuration parameter is used for defining the division of uplink resource blocks between PRACH and PUSCH. Load statistics on RACH and PUSCH are collected used for determining a number of RACH opportunities required per time unit. Then a new PRACH configuration parameter having said required number of RACH opportunities per time unit is selected which is replacing the old PRACH configuration parameter.
