Patent ID: 8787826

Claim:
A method of accessing to a network node in a wireless communication system, comprising: receiving, by a relay node (RN), a network node list from a network, the network node list including information about at least one network node which is allowed to access; selecting, by the RN, a network node from the network node list; and connecting, by the RN, to the selected network node, wherein the network node list includes at least one relay node allow indicator (RNAI) and at least one network node indicator (NNI), each RNAI indicating whether each network node is allowed to access and each NNI indicating a type of the each network node, the type being a relay node or a base station; wherein the step of the selecting the network node includes: determining the each network node is allowed to access based on the at least one RNAI; and selecting the network node among the at least one allowed network node by comparing the type of each allowed network node based on the at least one NNI and a predetermined preference type.
