heal.abstract	Power constitutes an essential controllable resource for the improvement of the radio link performance in Wideband Code Division Multiple Access (WCDMA)-based cellular networks. In addition, complementary to traditional services, location-based services (LBS) have emerged as a growing area for mobile service providers bringing in the foreground the potential for a location-aware resource management. To this effect, this paper addresses a location- and service-aware downlink transmission power allocation problem (DTPA), the solution of which is suitable for the management or control domain of multi-service, WCDMA-based cellular networks. Given a specific traffic load situation that includes location and required service information, the solution of the DTPA problem aims at finding the optimum feasible allocation of power to the set of downlink connections that should be supported by the system. The problem is concisely defined, mathematically formulated and solved by a computationally efficient algorithm. Simulation and numerical results are presented.	en
