METHOD FOR QUALITY OF SERVICE DIFFERENTIATION IN PACKET-MODE MOBILE COMMUNICATION NETWORKS

The method involves determining a total priority level for access to network resources at the level of nodes (BSS/RNC, SGSN, GGSN) of a mobile communication network. The priority level is defined by a combination of service quality parameters related to a type of service with service quality parameters related to a priority level of a subscriber. A predefined service quality process is applied to a data flow. The data flow corresponds to the service based on the level of determined total priority. The determination process and the quality process application process are performed based on network overload at the time of access to the resources.
