摘要 |
A local breakout session establishment method and apparatus in an Evolved Packet System (EPS) is provided for an HeNB to efficiently route local IP packets. A local breakout service method for a wireless communication system including a macro evolved Node B (eNB) and a Home eNB (HeNB) having a Packet Data Network (PDN) gateway (PGW) and a serving gateway (SGW) includes selecting, at a Mobility Management Entity (MME), the PGW of the HeNB and transmitting a Create Default Bearer Request message to the HeNB in response to a local breakout service request message including a local breakout Access Point Name (APN); assigning, at the HeNB, an IP address to a user equipment transmitted the local breakout service request message and transmitting a Create Default Bearer Response message including a Tunnel Endpoint Identifier (TEID) to the MME; transmitting a Bearer Setup Request message including the TEID from the MME to the HeNB; and configuring, at the HeNB, a radio bearer with the user equipment and routing data transmitted by the user equipment through the radio bearer to an Internet Protocol (IP) network by means of the internal PGW. |

1. A method of providing a local breakout service of a mobility management entity (MME) in a wireless communication system, comprising:
receiving a connection request message; transmitting a location update message including an address of a home evolved Node B (HeNB); determining whether local breakout access point name (APN) information is contained in the connection request message; selecting a packet data network (PDN) gateway (PGW) corresponding to the HeNB according to the address of the HeNB provided by a home subscriber server (HSS) if the local breakout APN information is contained in the connection request message; and transmitting a create default bearer request message to the selected PGW to create a default bearer. |
