HSIFLS trial on Tripoli The document summarizes a trial of HSDPA Inter-Frequency Load Sharing (HSIFLS) on the city of Tripoli. It describes the HSIFLS feature, parameters that can be configured like threshold levels, and monitoring counters. The trial tested different threshold scenarios to prioritize load sharing between two carriers and equally distribute HS users and load for better spectrum efficiency and lower rejections. The recommended scenario was found to be using a threshold around 35% to balance traffic.
