Optimizing the Traffic of Voice Core Domain in UMTS Network through RNC Re-homing
 

by:  Ye Ouyang and M. Hosein Fallah, Ph.D., P.E.

The past few years have seen mobile operators transition to next-generation mobile networks; specifically from third-generation networks (3G) to long term evolution (LTE). This paper first describes the basic architecture and topology of UMTS R4 core network and introduces two options in network planning: flat structure or layered structure. This paper introduces the re-homing of radio network controller (RNC) and base station controller (BSC) and studies the impact on the performance of voice core of UMTS networks. The proposed RNC re-homing models are created and analyzed for voice core of UMTS networks. The paper concludes that the appropriate RNC re-homing optimizes the traffic of voice core in UMTS network,  improves the QoS of the core network and saves the carriers’ OPEX and CAPEX on their core networks.
