Abstract
An apparatus and method for determining validity of a Wireless Fidelity (WiFi) connection in a wireless apparatus is provided. In the method, a query is performed on a specific Domain Name Server (DNS) via a connected Access Point (AP). When a response to the query on the specific DNS is received, a connection to a specific node is attempted via the connected AP. When the connection to the specific node is successful, a valid WiFi connection is determined. The WiFi connection is maintained. Therefore, a WiFi apparatus is allowed to connect to only a valid AP, so that convenience is provided to a user and the WiFi apparatus is prevented from wasting power.
Claims18
A method for determining validity of a Wireless Fidelity (WiFi) connection in a wireless communication system, the method comprising:
- performing a query on a specific Domain Name Server (DNS) via a connected Access Point (AP);
- when receiving a response to the query on the specific DNS, attempting a connection to a specific node via the connected AP;
- when the connection to the specific node is successful, determining that a WiFi connection is valid;
- and
- maintaining the WiFi connection.
An apparatus for determining validity of a Wireless Fidelity (WiFi) connection in a wireless communication system, the apparatus comprising:
- a controller for performing a query on a specific Domain Name Server (DNS) via a connected Access Point (AP), when receiving a response to the query on the specific DNS, for attempting a connection to a specific node via the connected AP, when the connection to the specific node is successful, for determining that a WiFi connection is valid, and for maintaining the WiFi connection;
- a display unit for displaying information output by the controller;
- an input unit for providing a user's input to the controller;
- and
- a WiFi modem for transmitting information output for transmission by the controller, for providing received information to the controller, and for communicating via the AP.
