Fast development and implementation of new telecommunicationservices and Intelligent Transp01t Systems (ITS) havecreated new environment for the network telecom operatorsand service providers and logistic and transport enterprises. Thecmcial issue for successful business and other professional applicationsis the provision of the end-to-end quality of service inthe inter-network operation of mobile and fixed networks. Theproblem was less expressed in the traditional networks orientedto telephony, but the issue of different QoS algorithms growswith the spreading of data transmission services and multimediaapplications. The existence of different QoS algorithms andprocedures in the !?-based networks (JP- Internet Protocol)also makes difficult the finding of a single solution for the implementationofQoS in the !?-based networks. In the indicatedcontext this work systemically defines the problem of providinga single end-to-end QoS protocol in the connected UMTS/IPnetworks. The possibilities of its realization are presented on theexample of two protocols. The work gives the basic characteristicsof the two protocols that fulfil the criteria set in the realizationof the new generation of mobile networks.
