Abstract

A synchronization method between an application and Internet protocol included in a mobile terminal including determining whether or not an Internet Function can be performed by the Internet protocol and issuing a wait command from the Internet protocol to the application when it is determined the Internet function can not be performed so as to inform the application to wait a predetermined period of time before closing communication with the Internet protocol.

Claims

1. A synchronization method between an application and Internet protocol included in a mobile terminal, the synchronization method comprising:

issuing an Internet function request from the application to the Internet protocol to request the Internet protocol perform data transmission, wherein the application comprises a Wireless Application Protocol (WAP) and the Internet protocol comprises a Transmission Control Protocol/Internet Protocol (TCP/IP);

determining whether an Internet function can be performed by the Internet protocol, wherein the Internet protocol determines whether there is a sufficient amount of space in a buffer of the mobile terminal to perform the request for data transmission;

issuing a wait command from the Internet protocol to the application when it is determined the Internet function can not be performed so as to inform the application to wait a predetermined period of time before closing communication with the Internet protocol;

issuing an event notification command from the Internet protocol to the application when it is determined the Internet function can be performed so that the application does not issue repetitively the Internet function request;

reissuing the Internet function request from the application to the Internet protocol to request the Internet protocol perform the Internet function; and

performing at least one other task while waiting for an event notification.

2. The synchronization method of claim 1, further comprising:

performing the Internet function after receiving the reissued request.

3. The synchronization method of claim 1, wherein issuing the Internet function request comprises issuing a request for data reception.

4. The synchronization method of claim 3, wherein determining whether the Internet function can be performed comprises:

determining whether the Internet protocol has received data corresponding to the request for data reception.

5. The synchronization method of claim 1, wherein issuing the Internet function request comprises issuing a request for accepting a connection request from an external source.

6. The synchronization method of claim 5, wherein determining whether the Internet function can be performed comprises:

determining whether the Internet protocol has received the connection request from the external source.

7. A mobile terminal, comprising:

an application configured to request an Internet function that issues a request for data transmission; and

an Internet protocol configured to determine whether the Internet function can be performed, and to issue a wait command to the application when it is determined the Internet function can not be performed so as to inform the application to wait a predetermined period of time before closing communication with the Internet protocol, wherein the Internet protocol determines whether there is a sufficient amount of space in a buffer of the mobile terminal to perform the request for data transmission, wherein the Internet protocol issues an event notification command to the application when it is determined the Internet function can be performed so that the application does not issue repetitively the Internet function request, wherein when the wait command is issued, the application can perform at least one other task while waiting for an event notification, wherein the application reissues the Internet function request to the Internet protocol after receiving the event notification from the Internet protocol to request the Internet protocol perform the Internet function, and wherein the application comprises a Wireless Application Protocol (WAP) and the Internet protocol comprises a Transmission Control Protocol/Internet Protocol (TCP/IP).

8. The mobile terminal of claim 7, wherein the Internet protocol performs the Internet function after receiving the reissued request.

9. The mobile terminal of claim 7, wherein the application issuing the Internet function requests issues a request for data reception.

10. The mobile terminal of claim 9, wherein the Internet protocol determining whether the Internet function can be performed determines whether the Internet protocol has received data corresponding to the request for data reception.

11. The mobile terminal of claim 7, wherein the application issuing the Internet function requests issues a request for accepting a connection request from an external source.

12. The mobile terminal of claim 11, wherein the Internet protocol determining whether the Internet function can be performed determines whether the Internet protocol has received the connection request from the external source.

13. A synchronization method between an application and an Internet protocol included in a mobile terminal, the synchronization method comprising:

requesting the Internet protocol perform an Internet function from the application to the Internet, comprising requesting data transmission, wherein the Internet protocol determines whether there is a sufficient amount of space in a buffer of the mobile terminal to perform the request for data transmission, and wherein the application comprises a Wireless Application Protocol (WAP) and the Internet protocol comprises a Transmission Control Protocol/Internet Protocol (TCP/IP);

trying to perform at least one of data transmission, data reception, and accepting connection request of an external client between the application and the Internet protocol; and

performing at least one other task while waiting for an event notification.

14. A mobile terminal, comprising:

an Internet protocol configured to determine whether an Internet function can be performed when a request from an application for the Internet function is received, wherein the request from the application for the Internet function comprises a request for data transmission, wherein the Internet protocol determines whether there is a sufficient amount of space in a buffer of the mobile terminal to perform the request for data transmission; and

an application configured to request the Internet function and perform at least one other task while waiting for confirmation from the Internet protocol, wherein the application comprises a Wireless Application Protocol (WAP) and the Internet protocol comprises a Transmission Control Protocol/Internet Protocol (TCP/IP).
