A Radio Network Controller, RNC, and a method performed by the RNC for managing the utilisation of a RACH of a WCDMA communication network wherein the RNC is associated with an RBS, wherein the RACH is an uplink channel between UEs and the RBS are provided. The method comprises determining a current resource utilisation level of the RACH; setting, based on the determined resource utilisation, a value of at least one Radio Link Control, RLC, parameter that controls the disposition of a UE to transmit data on the RACH; and employing the at least one RLC parameter to at least one UE being in a Cell Forward Access Channel, CELL_FACH, state or entering into the CELL_FACH state. 1. A method performed by a Radio Network Controller , RNC , for managing the utilisation of a Random Access Channel , RACH , of a Wideband Code Division Multiple Access , WCDMA , communication network , the RNC being associated with a Radio Base Station , RBS , wherein the RACH is an uplink channel between User Equipments , UEs , and the RBS , the method comprising:determining a current resource utilisation level of the RACH;setting, based on the determined resource utilisation, a value of at least one Radio Link Control, RLC, parameter that controls the disposition of a UE to transmit data on the RACH; andemploying the at least one RLC parameter to at least one UE being in a Cell Forward Access Channel, CELL_FACH, state or entering into the CELL_FACH state.2. The method according to claim 1 , further comprising signalling the at least one RLC parameter to at least one UE being in a Cell Forward Access Channel claim 1 , CELL_FACH claim 1 , state or entering into the CELL_FACH state.3. The method according to claim 1 , wherein the at least one RLC parameter controls the UE disposition to transmit or retransmit a data packet while awaiting acknowledgement on a previously transmitted data packet.4. The method according to claim 1 , wherein the RLC parameters are set per UE currently being connected ...
