Abstract

A pairing method and an apparatus thereof for an ad-hoc connection in a wireless communication terminal are provided. In the method, an event duration that occurs according to user manipulation is measured. A pairing key is generated using the measured duration. A pairing procedure is performed with a counterpart terminal using the pairing key.

Claims

1. A pairing method for a connection in a wireless communication terminal, the method comprising:

measuring, by a timer, an event duration that occurs according to user manipulation;

generating, by a pairing key generator, a pairing key using the measured duration; and

performing, by a communication module, a pairing procedure with a counterpart terminal using the pairing key, wherein the generating of the pairing key using the measured duration comprises applying a conversion function to the measured duration, wherein the applying of the conversion function to the measured duration comprises;

performing a normalization operation on the measured duration; and

applying the conversion function to a value obtained by the normalization operation, wherein the normalization operation is performed using;

C=(Δ

−

Δ

%G)/G

where Δ

denotes the measured time, and G denotes a reference value set in advance.

2. The method of claim 1, wherein the event according to the user manipulation comprises at least one of a key input, a screen touch, sound generation, and light generation.

3. The method of claim 1, wherein the performing of the normalization operation comprises:

displaying a normalization operation result value and at least one value neighboring the result value; and

determining one of the displayed values by the user.

4. The method of claim 3, wherein while the normalization operation result value and the at least one value neighboring the result value are displayed, at least one effect of color, thickness, size, background color, and background pattern is given to each value.

5. The method of claim 1, further comprising:

determining one conversion function from a plurality of conversion functions according to the value obtained by the normalization operation.

6. The method of claim 1, wherein the connection is ad-hoc connection, and

wherein the pairing key comprises at least one of a Service Set IDentifier (SSID), a web key, a device name, and a PIN number.

7. The method of claim 6, wherein at least one of the SSID, the web key, the device name, and the PIN number is generated by dividing the pairing key using a predetermined method.

8. A pairing apparatus for a connection in a wireless communication terminal, the apparatus comprising:

a timer for measuring an event duration that occurs according to user manipulation;

a pairing key generator for generating a pairing key using the measured duration; and

a communication module for performing a pairing procedure with a counterpart terminal using the pairing key, wherein the pairing key generator applies a conversion function to the measured duration, wherein the pairing key generator performs a normalization operation on the measured duration, and applies the conversion function to a value obtained by the normalization operation, wherein the pairing key generator performs the normalization operation using;

C=(Δ

−

Δ

%G)/G

where Δ

denotes the measured time, and G denotes a reference value set in advance.

9. The apparatus of claim 8, wherein the event according to the user manipulation comprises at least one of a key input, a screen touch, sound generation, and light generation.

10. The apparatus of claim 8, wherein the pairing key generator controls displaying of the normalization operation result value and at least one value neighboring the result value, and determine one of the displayed values by the user.

11. The apparatus of claim 10, wherein when the displaying of the normalization operation result value and the at least one value neighboring the result value, the pairing key generator gives at least one effect of color, thickness, size, background color, and background pattern to the value.

12. The apparatus of claim 8, wherein the pairing key generator determines one conversion function from a plurality of conversion functions according to the value obtained by the normalization operation.

13. The apparatus of claim 8, wherein the connection is ad-hoc connection, and

wherein the pairing key comprises at least one of a Service Set IDentifier (SSID), a web key, a device name, and a PIN number.

14. The apparatus of claim 13, wherein the pairing key generator generates at least one of the SSID, the web key, the device name, and the PIN number by dividing the pairing key using a predetermined method.
