An authentication method for user equipment (UE) and LIPA network entities is applicable to a cross-LIPA communication environment having an UE end, a visiting LIPA network entity end (LIPA), and a home LIPA network entity end (LIPA). The UE end successfully registers to a core network (CN) via the LIPA, thereby attaining mutual trust relationship between the UE end and the LIPA. The UE end successfully registers to the CN via the LIPA, thereby attaining mutual trust relationship between the UE end and the LIPA. The LIPArequests the UE end via the LIPAfor successfully re-authenticating the CN, thereby attaining mutual trust relationship between the LIPAand the LIPA.
