and transmitting the local network SIPTO PDN connection indication information to the UE, wherein the local network SIPTO PDN connection indication information can express whether the PDN connection of the UE is a local network SIPTO PDN connection. ## Claims ### Claim 1 A method for transmitting local network Selected Internet Protocol Traffic Offload (SIPTO) indication information, comprising: generating local network SIPTO PDN connection indication information regarding Packet Data Network (PDN) connection of a user equipment (UE) in a first network node; and transmitting the local network SIPTO PDN connection indication information from the first network node to the UE, wherein the local network SIPTO PDN connection indication information indicates whether the UE PDN connection is identical to local network SIPTO PDN connection. ### Claim 2 (depends on 1) The method according to claim 1, wherein the local network SIPTO PDN connection indication information is defined as charging-related information for identifying the local network SIPTO PDN connection. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: transmitting the local network SIPTO PDN connection indication information from the first network node to a PDN gateway node through a serving gateway node. ### Claim 4 (depends on 3) The method according to claim 3, wherein: through the PDN gateway node, a charging system applied to the local network SIPTO PDN connection is determined on the basis of the local network SIPTO PDN connection indication information. ### Claim 5 (depends on 1) The method according to claim 1, wherein the local network SIPTO PDN connection indication information transmitted to the UE is defined as specific information indicating a connectivity type selected for the UE PDN connection. ### Claim 6 (depends on 1) The method according to claim 1, wherein: specific information indicating whether a data session of the UE PDN connection is maintained during handover of the UE is determined on the basis of the local network SIPTO PDN connection indication information. ### Claim 7 (depends on 1) The method according to claim 1, wherein: specific information indicating whether local network SIPTO for the UE is permitted is applied to the first network node by a database. ### Claim 8 (depends on 7) The method according to claim 7, wherein: the database is a network node for storing/managing at least one of subscriber information of the UE, Closed Subscriber Group (CSG) information, and group information for Managed Remote Access (MRA); and the specific information indicating whether the local network SIPTO is permitted is contained in at least one of the subscriber information, the CSG information, and the MRA group information. ### Claim 9 (depends on 1) The method according to claim 1, wherein the first network node is a Mobility Management Entity (MME). ### Claim 10 A method for receiving local network Selected Internet Protocol Traffic Offload (SIPTO) indication information, comprising: receiving local network SIPTO PDN connection indication information indicating whether Packet Data Network (PDN) connection of a user equipment (UE) is local network SIPTO PDN connection from a first network node, wherein the local network SIPTO PDN connection indication information is generated in the first network node. ### Claim 11 An apparatus for transmitting local network Selected Internet Protocol Traffic Offload (SIPTO) indication information, comprising: a transceiver module configured to transmit/receive a signal to/from an external part; a processor configured to control the transceiver module, wherein the processor is configured to generate local network SIPTO PDN connection indication information regarding Packet Data Network (PDN) connection of a user equipment (UE), and is configured to transmit the local network SIPTO PDN connection indication information to the UE through the transceiver module, wherein the local network SIPTO PDN connection indication information indicates whether the UE PDN connection is identical to local network SIPTO PDN connection. ### Claim 12 An apparatus for receiving local network Selected Internet Protocol Traffic Offload (SIPTO) indication information, comprising: a transceiver module configured to transmit/receive a signal to/from an external part; a processor configured to control the transceiver module, wherein the processor is configured to receive local network SIPTO PDN connection indication information indicating whether Packet Data Network (PDN) connection of a user equipment (UE) is local network SIPTO PDN connection from a first network node through the transceiver module, wherein the local network SIPTO PDN connection indication information is generated in the first network node.
