Interworking between UMTS (Universal Mobile Telecommunications System) and external networks is an important concept for fixed-mobile convergence as well as for next generation network. In order to achieve end-to-end QoS (Quality of Service) for broadband multimedia real-time services, DiffServ (Differentiated Services) mechanism should be used as QoS model and mapping of DiffServ Code Points (DSCP) into UMTS traffic classes should be applied to get efficient PHB (Per Hop Behaviour) configurations. According to the 3GPP specifications, standard QoS mapping between IP QoS classes and UMTS services authorizes both voice and video telephony to be mapped to the same QoS class.
