A method for handling communication between a user equipment and a radio network controller of an UMTS (Universal Mobile Telecommunications System) radio access network includes: providing a transmission instruction by the radio network controller for redirecting the user equipment to a target carrier frequency, the target carrier frequency being an allowed frequency of a local access radio network; evaluating if the target carrier frequency is interfered by the local access radio network near the user equipment; and preventing a redirection of the user equipment to the target carrier frequency by the radio network controller for a certain time period, if the target carrier frequency is interfered by the local access network near the user equipment.
