The proposed PFC is in the framework of Radio Resources Management and Quality of Service (QoS) for CDMA based radio access networks (such as UMTS). One of the fundamental facts of these systems is to provide different types of multimedia services in order to guarantee certain quality requirements in the connections. The Radio Resources Management strategies (RRM) are in charge of controlling the different radio network parameters so guaranteeing the quality required to the connections and making a use efficient of the resources available. For the case of the uplink, it is very important to determine the format of transmission of the users, i.e., the rate of transmission that the user will have at every moment. The main objective of this PFC is to propose and to evaluate different strategies of user transmission format allocation of background service (for example e-mail), in order to optimize the trade-off between the obtained e-mail users delay and the level of interferences that is added to the system. A simulator programmed in C is available. This simulator models a real WCDMA system. Introducing the game theory as a RRM strategy is possible to add one more strategy to current strategies. These analyses show a proposal and evaluation of three strategies: ThMS, RM and a this new algorithm based in the game theory, and of course a check of its performance.
