The invention relates to a method for managing radio resources allocated by the radio network controller of an UTRAN radio access network. Said resources support a plurality of service requests each of which is identified by a service support request for radio access transmitted by a core network and describes an QoS requested in the form of a totality of RAB parameters defined by mapping with thecorresponding QoS parameters of the core network. The controller is used for distributing resources amongst different support services and for modulating and allocating said resources according to apriority level associated with each support service. The priority level is defined by the priority level subparameter of the RAB Allocation Retention Priority parameter whose value is determined by taking into consideration the said QoS Allocation Retention Priority parameter of the core network and the value of at least one QoS parameter associated with a type of service.
