Abstract

A UMTS (Universal Mobile Telecommunications System) core network supports the negotiation of variable quality of service (QoS). A QoS information element (IE) is defined that supports downgradeable QoS requirements by allowing multiple traffic classes to be specified in a priority order. Similarly, a QoS information element (IE) is defined that supports upgradeable QoS requirements.
