1. A wireless network system comprising:
- a first access point which exists on a wireless network; and
a user terminal which accesses the first access point;
wherein the first access point periodically analyzes information on a performance of a plurality of access points and transmits the analyzed information about a second access point, which is one of the plurality of access points accessible by the user terminal, to the user terminal, andwherein the user terminal determines whether to access the second access point and accesses the second access point in accordance with a result of the determination, andwherein the first access point transmits the analyzed information if a transmission quality of the first access point is deteriorated,wherein in accessing the first access point the user terminal transmits a probe request packet, receives probe response packets in response to the probe request packet from the plurality of access points, selects and accesses the first access point, and transmits information about the plurality of access points to the first access point.

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.
