Abstract: The present invention provides a method for using Differentiated Services (DiffServ) to implement the IP packet classification and the marking of a Differential Service Code Point (DSCP) for the quality of service (QoS) in the wireless access network of the IP-based universal mobile telecommunication system (UMTS). The present invention makes a classification to the data stream which is outgoing from the Iub interface at the Node B side, data stream which is outgoing from the Iub interface at the RNC side and data stream which is outgoing from the Iur interface at the RNC side according to the direction and the process of the respective data streams, and assigns and adjusts the priority of the data stream classified according to the principles for optimizing QoS and radio resources. When the network is congested, the data stream with a high level will have a higher priority than that with a lower level in queue and source occupancy, and the packet with a lower priority in the same queue is discarded. The DiffServ only contains a limited number of service levels and has little condition information, thus easy to be achieved and expanded.

Abstract: A method and system for estimating an angular position and an angular velocity of a rotor in a dynamoelectric machine measures an AC current and a potential for each of a plurality of windings coupled to a stator of the dynamoelectric machine, transforms the measured currents and potentials to a stationary frame to produce transformed currents and transformed potentials, and processes the transformed currents and transformed potentials to produce a first intermediate signal and a second intermediate signal. The first intermediate signal and the second intermediate signal are cross-coupled by being processed to obtain a first extended rotor flux value and a second extended rotor flux value that are each functions of the first intermediate signal and the second intermediate signal. The first extended rotor flux value and the second extended rotor flux value are applied to a phase lock loop to derive an estimated rotor angular position and an estimated rotor angular velocity for the dynamoelectric machine.
