The RNC has the same possible advantages as the method performed by the RNC and the RNC described above with reference to FIG. 2. One possible advantage is that by dynamically setting (or changing) the RLC parameters, a possible deterioration of the random access channel may be prevented in high load scenarios, while allowing for high performance in low load scenarios. Since the RACH is sensitive to high load and a well-functioning random access that can handle signalling from UEs to the network is a key component in e.g. ensuring emergency and speech accessibility, it is important that the quality of the RACH is not allowed to deteriorate as the number of UEs in the network (or being connected to the RBS) increases. Meanwhile, the end-user experience for UEs in CELL_FACH state is dependent on the network allowing for as much data transmission as possible on the RACH without creating problems.
