METHOD FOR PROVIDING MOBILITY BETWEEN THE LOCAL NETWORKS AND LOCAL GATEWAY THEREOF CAPABLE OF TRANSMITTING DATA RECEIVED FROM A PACKET DATA NETWORK TO A TARGET LOCAL BASE STATION THROUGH A LOCAL TARGET INTERFACE AND A LOCAL TARGET GATEWAY

摘要

PURPOSE: A method for providing mobility between the local networks and local gateway thereof are provided to reduce traffic concentration in a specific apparatus and traffic transmission paths.;CONSTITUTION: A source L-GW(local-gateway) of a source local network data received from a packet data network to UE(user equipment) connected to the source L-GW through a source HeNB(home enodeb)(S300). The source HeNB of an UE cell is converted into a target HeNB connected with the target L-GW of a neighbor target local network(S302). The source L-GW transmits the data received from the packet data network to the UE through tunneling of the data in the target HeNB by using the interface and the target L-GW(S304,S306).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S300) Data transmission step before moving a terminal; (S302) Cell conversion step according to moving a terminal; (S304) Signaling step; (S306) Data forwarding step through tunneling
