Embodiments herein also relate to an RNC 200 for managing the utilisation of a RACH of a WCDMA communication network, the RNC being associated with an RBS, wherein the RACH is an uplink channel between UEs and the RBS. The RNC has the same objects, technical features and advantages as the method performed by the RNC and the RNC described above with reference to FIG. 2. The RNC will only be described in brief in order to avoid unnecessary repetition, with reference to FIG. 3.

FIG. 3 is a block diagram of an RNC for managing the utilisation of a RACH of a WCDMA communication network according to an exemplifying embodiment.

FIG. 3 illustrates the RNC 200 comprising a determining unit 303 for determining a current resource utilisation level of the RACH; a setting unit 304 for 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 an employing unit 305 for 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
