“…P GB + P NGB ) reaches the overload threshold, denoted by P TxTotal + Offset, the NGB allocated bit rates are accordingly reduced by LC and in turn immediately resumed when the P GB decreases and the system backs off to its normal state of operation. Furthermore, the measured GB load (P GB ) hardly ever trespasses the target threshold (P TxTarget ) defined in (2), which confirms the accuracy of (3) in the power estimates during the admission control and bit rate allocations. Ultimately, following the input traffic mix, P TxTotal preserves its point of equilibrium (P TxTarget ), which thus validates the supported AC and PC functions.…”

“…For this purpose, several tools were presented in the literature, e.g. : A static simulator for WCDMA radio network planning was presented in [2], and an advanced WCDMA dynamic simulator for detailed analyses of RRM functions was described in [3]. Evaluation of the suitability and accuracy of such tools, as well as a comparison of thereof can be found in [4] and [5].…”

“…Conversely, dynamic system level simulators typically run with far too high time resolution and require lengthy simulation times to design networks and/or analyze thoroughly the deployment of application services. This paper describes a virtual time simulator that overcomes the limitations of the static tool presented in [2], and the complexity of the dynamic simulator discussed in [3]. The tool enhances the version described in [6] with multi-cell propagation scenarios and realistic RRM functions as implemented in [2] and [3], respectively.…”

Also, for more accurate analyses, the simulator includes: User definable traffic models for packet switched streaming, Push to Talk over Cellular (PoC), See What I See (SWIS, or real time video sharing, RTVS), Multimedia Messaging (MMS), WAP and Dialup connections [7]; and the possibility of monitoring system and service performances as recommended in [8].…”

Abstract. This paper describes an enhanced virtual time simulator for studying the provisioning of new services throughout the UMTS Radio Access Network (UTRAN). Several simulations were run to verify the feasibility of the tool and to investigate the effectiveness of the supported QoS mechanisms. The radio resources utilization is analyzed in terms of cell throughput and transmission power. The quality of experience is assessed separately for each of the offered services by tailored combinations of performance metrics, which determine the degree of satisfaction of the user of the services. The simulation results show the proposed simulator to be an appropriate tool for studying several aspects of radio network management, such as service planning and QoS provisioning.

Abstract-A system-level model for power control in the uplink of direct-sequence code-division multiple access (DS-CDMA) cellular networks is presented. The model takes into account the effects of the closed loop, namely average transmit power rise, power headroom, and variable soft hand-off gains, which are not considered in existing power control models. The power control problem is analyzed in this setting, and a number of properties are derived which generalize results from the classical model without closed-loop effects. Based on this analysis, an algorithm is given that determines required transmit powers taking into account these effects. This algorithm is a generalization of classical iterative algorithms without closed-loop effects. Finally, simulation results are presented to assess the validity of the approach.
