heal.abstract	In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks supporting simultaneously both real-time and non-real-time services with various and often diverse Quality of Service (QoS) prerequisites. Each mobile is associated with a nested QoS-aware utility function that characterizes its degree of satisfaction for the received service in terms of achieved goodput and corresponding power consumption. The problem is formulated as a non-convex non-cooperative Multi-Service Uplink Power Control (MSUPC) game where users aim selfishly at maximizing their utility-based performance under the imposed physical limitations. We first prove the existence and uniqueness of a Nash equilibrium point of MSUPC game, and then a distributed iterative algorithm is proposed in order to obtain MSUPC game's equilibrium point. Finally, the efficacy of the proposed approach with respect to the fulfillment of both types of services' QoS requirements is extensively illustrated via modeling and simulation.
