Claim Text:
1. A method for transmitting, by a home evolved NodeB (HeNB)/X2-proxy, a transport network layer (TNL) address in a wireless communication system, the method comprising: receiving a mobility management entity (MME) configuration transfer message from a MME, the MME configuration transfer message including an indication of whether a direct X2 interface or an indirect X2 interface is to be established between a macro evolved NodeB (eNB) and a HeNB, the indication being generated by the macro eNB; forwarding the MME configuration transfer message to the HeNB; receiving an eNB configuration transfer message from the HeNB, the eNB configuration transfer message including a TNL address of the HeNB and an eNB identifier (ID) of the HeNB; and upon receiving the eNB configuration transfer message from the HeNB, determining a TNL address and an eNB ID to be transmitted to the MME in the eNB configuration transfer message based on the indication of whether the direct X2 interface or the indirect X2 interface is to be established between the macro eNB and the HeNB.
