Quality of Services in Integrated UMTS/IP Networks

Fast development and implementation of new telecommunication services and Intelligent Transport Systems (ITS) have created new environment for the network telecom operators and service providers and logistic and transport enterprises. The crucial issue for successful business and other professional applications is the provision of the end-to-end quality of service in the inter-network operation of mobile and fixed networks. The problem was less expressed in the traditional networks oriented to telephony, but the issue of different QoS algorithms grows with the spreding of data transmission services and miltimedia applications. The existence of different QoS algorithms and procedures in the IP-based networks (IP - Internet Protocol) also makes difficult the finding of a single solution for the implementation of QoS in the IP-based networks. In the indicated context this work systemically defines the problem of providing a siingle end-to-end QoS protocol in the connected UMTS/IP networks. The possibilities of its realization are presented on the example of two protocols. The work gives the basic characteristics of the two protocols that fulfil the criteria set in the realization of the new generation of mobile networks.
