Abstract: A femto access point in a communication system provides an interface for a UE, an interface for a macro access point or a relay, and an interface for a core network.

Abstract: An apparatus and method for accessing a local network in a mobile communication system supporting a Local Network Internet Protocol Access (LIPA) scheme are provided. In the method, a User Equipment (UE) transmits a radio bearer set up request packet to a router connected to a femto Node B in order to set up a radio bearer with the femto Node B, thereby the router converts the radio bearer set up request packet into a port forward radio bearer set up request packet using a port forward function, and transmits the port forward radio bearer set up request packet to the femto Node B.
