LR13.1.L introduced in Alcatel-Lucents LTE RAN the support of 3G Iuh-based Small Cells (RRC release with

49、 redirection is supported only) Until LR14.1.L, CSFB to 3G Small Cells had been blocked. This feature, 170910, removes this restriction. Basic redirection to 3G Small Cells is enabled.FEATURE VALUE This feature allows UEs using LTE to “fall back” to a Circuit-Switched (CS) network when placing voice

50、 calls, even when the target cell to support the CS call is a 3G Iu-h Small Cell. The redirection-based CS fallback that is provided by this feature is not impacted by PSC confusion. Therefore, CS fallback based on redirection is preferable to a Packet Switch (PS) Handoff (HO) because redirection-ba
