The Impact of Cell Site Re-Homing on the Performance of UMTS Core Networks

Mobile operators currently prefer optimizing their radio networks via re-homing or cutting over the cell sites in 2Gor 3G networks. The core network, as the parental part of radio network, is inevitably impacted by the re-homing inradio domain. This paper introduces the cell site re-homing in radio network and analyzes its impact on theperformance of GSM/UMTS core network. The possible re-homing models are created and analyzed for corenetworks. The paper concludes that appropriate re-homing in radio domain, using correct algorithms, not onlyoptimizes the radio network but also helps improve the QoS of the core network and saves the carriers’ OPEX andCAPEX on their core networks
