1. A wireless network-based user terminal, comprising:
- a probe request packet transmitting unit to transmit a probe request packet through a wireless network;
a probe response packet receiving unit to receive probe response packets in response to the probe request packet;
an access point information storage unit to store information on accessible access points based on the received probe response packets;
a terminal control unit to select and connect to one of the accessible access points, and control transmission of the information on the accessible access points to a selected access point;
wherein the user terminal transmits the probe request packet in an active scan method by successively transmitting probe request packets to the access points existing in the network,wherein the user terminal transmits new information on accessible access points by periodically searching for surrounding access points, andwherein the probe response packet receiving unit receives a probe response packet including information on a list of recommended access points based on state information of the accessible access points from.

Abstract
An apparatus and method of changing an access point in a wireless network system is provided. The wireless network system includes a first access point existing on a wireless network, and a user terminal accessing the first access point. The first access point transmits information on a second access point, which is one of a plurality of access points accessible by the user terminal, to the user terminal, and the user terminal determines whether to access the second access point and accesses the second access terminal in accordance with the determination result.
