Abstract

A method for a wireless Internet communication in a mobile communication terminal is provided. In an operation of starting a wireless Internet function, it is determined if a data call is being serviced and, if a data call is not serviced, the wireless Internet function is started by setting the wireless Internet function as a data call. In an operation of originating or terminating a voice call, it is determined if a wireless Internet function is being performed and, if the wireless Internet function is being performed, the wireless Internet function and a voice call service are substantially simultaneously started. Accordingly, in the wireless Internet communication method of the mobile communication terminal, a W-LAN function is set in the same manner as that in which a CDMA data call is set through modification of the SVD scheme, so that a W-LAN data protocol such as the DHCP (which can be used when the W-LAN function is set) and a voice call service can be provided at the same time. Herein, when software that does not support data concurrency is employed, it is possible to prevent the origination of a CDMA data call capable of causing an erroneous operation during the W-LAN operation.

Claims

1. A method for wireless Internet communication in a mobile communication terminal, the method comprising the steps of:

in an operation of starting a wireless Internet function, determining if a data call is being serviced; and

if a data call is not being serviced, starting the wireless Internet function by setting the wireless Internet function as a data call.

2. The method as claimed in claim 1, further comprising the steps of:

in an operation of originating or terminating a voice call, determining if a wireless Internet function is being performed; and

if the wireless Internet function is being performed, substantially simultaneously starting the wireless Internet function and a voice call service.

3. The method as claimed in claim 1, further comprising the steps of:

in an operation of originating or terminating a voice call, determining if a wireless Internet function is being performed; and

if the wireless Internet function is being performed, establishing the wireless Internet function to be substantially concurrent with a voice call service.

4. The method as claimed in claim 1, further comprising the steps of:

in an operation of originating a data call, determining if a wireless Internet function is being performed; and

if the wireless Internet function is not being performed, performing the operation of originating the data call.

5. A method for wireless Internet communication in a mobile communication terminal, the method comprising the steps of;

in an operation of starting a wireless Internet function, determining a number of calls currently serviced;

if the number of calls currently serviced is ‘

0’

, starting the wireless Internet function by setting the wireless Internet function as a data call;

if the number of calls currently serviced is ‘

1’

as the determination result, determining if a data call is connected; and

if the data call is not connected, starting substantially simultaneously the wireless Internet function and a voice call service by setting the wireless Internet function as a data call.

6. The method as claimed in claim 5, further comprising the steps of:

in an operation of originating a voice call, determining if a wireless Internet function is being performed;

if the wireless Internet function is being performed, substantially simultaneously starting the wireless Internet function and a voice call service;

if the wireless Internet function is not being performed, determining if the voice call is connected; and

if the voice call is not being connected, originating the voice call.

7. The method as claimed in claim 6, further comprising the steps of:

in an operation of receiving a voice call, determining if a wireless Internet function is being performed;

if the wireless Internet function is being performed, substantially simultaneously starting the wireless Internet function and a voice call service; and

if the wireless Internet function is not being performed, receiving the voice call.

8. The method as claimed in claim 7, further comprising the steps of:

in an operation of originating a data call, determining if a wireless Internet function is being performed; and

if the wireless Internet function is not being performed, originating the data call.

9. Program code embodied on a computer-readable medium for wireless Internet communication in a mobile communication terminal, the program code comprising:

a first set of instructions for determining if a data call is being serviced in an operation of starting a wireless Internet function; and

if a data call is not being serviced, a second set of instructions for starting the wireless Internet function by setting the wireless Internet function as a data call.

10. Program code as claimed in claim 9, further comprising:

in an operation of originating or terminating a voice call, a third set of instructions for determining if a wireless Internet function is being performed; and

if the wireless Internet function is being performed, a third set of instructions for substantially simultaneously starting the wireless Internet function and a voice call service.

11. Program code as claimed in claim 9, further comprising:

in an operation of originating or terminating a voice call, a third set of instructions for determining if a wireless Internet function is being performed; and

if the wireless Internet function is being performed, a fourth set of instructions for establishing a wireless Internet function that is substantially concurrent with a voice call service.

12. Program code as claimed in claim 9, further comprising:

in an operation of originating a data call, a third set of instructions for determining if a wireless Internet function is being performed; and

if the wireless Internet function is not being performed, a fourth set of instructions for performing the operation of originating the data call.

13. Program code embodied on a computer-readable medium for wireless Internet communication in a mobile communication terminal, the program code comprising;

in an operation of starting a wireless Internet function, a first set of instructions for determining a number of calls currently serviced;

if the number of calls currently serviced is ‘

0’

, a second set of instructions for starting the wireless Internet function by setting the wireless Internet function as a data call;

if the number of calls currently serviced is ‘

1’

as the determination result, a third set of instructions for determining if a data call is connected; and

if the data call is not connected, a fourth set of instructions for starting substantially simultaneously the wireless Internet function and a voice call service by setting the wireless Internet function as a data call.

14. The program code as claimed in claim 13, further comprising:

in an operation of originating a voice call, a fifth set of instructions for determining if a wireless Internet function is being performed;

if the wireless Internet function is being performed, a sixth set of instructions for substantially simultaneously starting the wireless Internet function and a voice call service;

if the wireless Internet function is not being performed, a seventh set of instructions for determining if the voice call is connected; and

if the voice call is not being connected, an eighth set of instructions for originating the voice call.

15. The program code as claimed in claim 14, further comprising:

in an operation of receiving a voice call, a ninth set of instructions for determining if a wireless Internet function is being performed;

if the wireless Internet function is being performed, a tenth set of instructions for substantially simultaneously starting the wireless Internet function and a voice call service; and

if the wireless Internet function is not being performed, an eleventh set of instructions for receiving the voice call.

16. The program code as claimed in claim 15, further comprising:

in an operation of originating a data call, a twelfth set of instructions for determining if a wireless Internet function is being performed; and

if the wireless Internet function is not being performed, a thirteenth set of instructions for originating the data call.
