Network Performance Evaluation of Abis Interface over DVB-S2 in the GSM over Satellite Network

This paper deals with establishing a GSM link over Satellite. Abis interface, which is defined between Base Transceiver Station (BTS) and Base Station Controller (BSC), in a GSM network is considered here to be routed over the Satellite. The satellite link enables a quick and cost-effective GSM link in meagerly populated areas. A different scenario comparison was done to understand the impact of Satellite environment on network availability comparing to terrestrial scenario. The authors have implemented an Abis interface over DVB S2 in NS2 and evaluated the performance over the high delay and loss satellite channel.
