ABSTRACT:
When UMTS is part of IP end-to-end communication, there must exist means for UMTS to be able to provide the required Quality of Service (QoS) for applications running over IP. Hence there is a need for a translation function for translation between IP QoS parameters and UMTS QoS attributes. This translation is not trivial because of several reasons. First, the number of QoS parameters in the IP level and the UMTS level are different. Second, definitions of parameters at the two levels are different. Keeping these factors in view, the present invention provides for a method for translation of IP QoS parameters to UMTS QoS attributes, and another method for translation of UMTS QoS attributes to IP QoS parameters. This translation will enable spectrum efficient UMTS bearers to be set up for applications running over IP. This will also make negotiation of services possible between an entity at the IP level and the UMTS network. These methods are placed in both the User Equipment as well as the Gateway of the UMTS network.
