Method, system and equipment for establishing LIPA connection

The embodiment of the invention discloses a method, a system and equipment for establishing LIPA (Local IP Access) connection, which relates to the technical field of wireless communication, and is used for solving the problems that no information of a CSG (Closed User Group) with UE (User Equipment) located therein exists in the subscription information of the terminal UE, and when an APN (Access Point Name) is allowed by the CSG to perform LIPA, the UE can not successfully perform LIPA. In the invention, a network side searches for the APN corresponding to a mark of the CSG with the currentterminal located therein from the corresponding relationship between the pre-configured CSG marks and the APN used for public access after receiving a connection request sent by a terminal, and the LIPA connection for the terminal is established after the searching, or the searched APN is sent to the UE and the UE subscription information is modified. By adopting the invention, the UE can successfully carry out LIPA.
