Abstract: A local Packet Data Network (PDN) access method of a User Equipment (UE) in a wireless communication system is provided. The local Packet Data Network (PDN) access method in a wireless communication system according to the present invention includes transmitting a local PDN connectivity request message from a base station to a Mobility Management Entity (MME); transmitting a bearer request message from the MME received the PDN connectivity request message to a Serving Gateway (SGW) proxy of the base station; forwarding the bearer request message from the SGW proxy to a PDN Gateway (PGW) proxy of the base station; transmitting a bearer response message indicating a local PDN access service of the base station in gateway mode from the PGW proxy to the SGW proxy; forwarding the bearer response message from the SGW to the MME; transmitting a bearer setup message from the MME received the bearer response message to the base station; and connecting a mobile terminal to the local PDN based on information contained in the bearer setup message.
