Capacity increase in mixed networks with EGPRS downlink power control

The progressive introduction of packet switched (PS) services in GSM networks involves interference control techniques that preserve the quality of speech communications. downlink power control (DLPC) for (E)GPRS reduces considerably the interference introduced by PS and notably increasing the system capacity Regina Rodriguez et al. (2002). The effect of this feature must be taken into account for network dimensioning purposes. This article presents a mathematical study about the equivalences that can be established in terms of interference between Erlang_PS and Erlang_CS in mixed environments when the downlink power control (DLPC) is applied to GPRS and EGPRS services.
