LOCAL NETWORK ACCESS DEVICE IN A MOBILE COMMUNICATIONS SYSTEM SUPPORTING A LOCAL NETWORK INTERNET PROTOCOL ACCESS METHOD ACCESSING A LOCAL NETWORK REGARDLESS OF THE LOCATION OF A USER EQUIPMENT AND A METHOD THEREOF

摘要

PURPOSE: A local network access device in a mobile communications system supporting a local network internet protocol access method and a method thereof are provided to automatically implement the selection of a network path corresponding to the location of a UE(User Equipment).;CONSTITUTION: A UE(211) transmits radio bearer setup request packets to a router(215) through a macro Node B(223), a core network(221), and a public network(219) to set up a femto-Node B(213) and a radio bearer. When receiving the radio bearer setup request packets, the router changes the radio bearer setup request packets to router-femto-Node B radio bearer setup request packets by using a port forward function, and transmits to the femto-Node B. The femto-Node B receives the router-femto-Node B radio bearer setup request packets from the router, allocates a local IP(Internet Protocol) address to the GGSN(Gateway GPRS Support Node) IP address of the UE, and generates a local network internet protocol access table.;COPYRIGHT KIPO 2013;[Reference numerals] (213) Femto-Node B; (215) Router; (217-1) Local host #1; (217-2) Local host #2; (217-3) Local host #3; (217-M) Local host #M; (219) Public network; (221) Core network; (223) Macro Node B; (AA) Wireless bearer setup;
