Abstract: The issue of converged networks is to ensure the sufficient quality of services for entire duration of communication transmission. This issue is closely connected to real- time services, such as VoIP (Voice over Internet Protocol) and videoconferencing. These services require strict adherence to quality parameters, otherwise their function is not guaranteed. IMS (IP Multimedia Subsystem) resolves this problem in perticular, which concluded on the basis of user profiles can provide the required quality of service. In the latest specifications of the Universal Mobile Telecommunication System (UMTS) networks, the 3GPP defines the IMS technology. That is why the multimedia sessions in the IMS are processed by a set of network elements originally designed to support IP multimedia services in the UMTS. The QoS mapping between IMS services and IP transport is fundamental for maintaining a suitable quality. The differentiation of these two technologies can lead to unpredictable and unwanted behavior for services. The possibility of employing DiffServ and IntServ mechanisms into the IMS environment in order to achieve full QoS support for real time applications is the object of interest.
