Abstract

A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In one embodiment, LIPA information is informed to the UE via Non Access Stratum (NAS) signaling. The UE stores LIPA capability information when receiving a NAS message from a mobility management entity (MME). Later on, when the UE performs cell selection or reselection in idle mode, the UE can use the stored LIPA capability information to prioritize LIPA-capable cells.
