Apparatus and method for supporting access in wireless communication system

An apparatus for supporting access in a wireless communication system, comprising:

• a checking unit configured to check all access nodes existing in a network through a plurality of stations (STA) which are to get access in the network and a plurality of access nodes of the respective STAs, and check a media access control (MAC)/physical (PHY) layer and channel available for the respective STAs in the network;
• a determination unit configured to determine access priorities of the checked STAs and priorities of the access nodes of the respective STAs, and determine the priorities of all the access nodes existing in the network from the determined priorities;
• a multiplexing unit configured to divide the checked MAC/PHY layer into multiple MAC/PHY layers, and divide the checked channel into multiple channels between which interference is minimized;
• and
• a connection unit configured to connect the multiple MAC/PHY layers to the multiple channels through a multi-channel MAC protocol such that the access nodes of the respective STAs are connected to the multiple MAC/PHY layers and the multiple channels such that each station has access to the respective access node via multiple channels, each handled separately,
• wherein the determination unit determines the priority of an intra-node serving as an internal access node of the respective STAs to be higher than the priority of an inter-user node serving as an access node between the respective STAs,
• wherein the connection unit uniformly allocates a home channel to the internal access nodes of the respective STAs through multi-rendezvous using the multi-channel MAC protocol, and connects the access nodes depending on the priorities of the access nodes of the respective STAs excluding access nodes which are already connected.
