Determining the resource utilisation level of the RACH may comprise measuring an RTT between the RNC and the at least one UE and/or an RTT between the RBS and the at least one UE.

Determining the resource utilisation level of the RACH may comprise receiving a report from the RBS.

Determining the resource utilisation level of the RACH may comprise measuring a RACH load in the RNC.

Determining the resource utilisation level of the RACH may comprise measuring the number of UEs being served by the RBS and currently being in CELL_FACH state.

Determining the resource utilisation level of the RACH may comprise measuring a FACH load of a downlink FACH channel associated with the uplink RACH channel.

According to an embodiment, the RLC parameters are set the same for all UEs being in CELL_FACH state or entering CELL_FACH state and being served by the RBS and sharing the RACH.

According to yet an embodiment, when the resource utilisation level of the RACH goes above the threshold at time T, the RLC parameter(s) are set to a new second value for all UEs which subsequently, after time T, becomes served by the RBS and entering CELL_FACH state and sharing the RACH, wherein the value of the RLC parameter(s) for the UEs already being in CELL_FACH state before time T keep the value of the at least one RLC parameter as it was set before time T occurred.
