Application QoS management for the reverse link of a 3G network

Abstract

Third generation (3G) wireless networks have been designed to provide high speed data services on both forward and reverse links. In addition to increased data capacity, they also support QoS (quality of service) for mobile users. Users may run multiple applications (service instances) simultaneously and QoS guarantees must be assured for one or more of them. We address the problem of providing QoS guarantees on the reverse link of a 3G (CDMA) network. We present a flexible, low overhead framework for efficient management of the reverse link resources to satisfy the QoS guarantees of each user's applications. We show how the QoS demands of all service instances of a particular user can be converted and combined into a single resource demand, namely the data rate of the corresponding reverse link channel.
