Abstract

A terminal and method of improving interference in a terminal are provided, by which interference generated from implementing a plurality of wireless communication technologies can be improved. The terminal includes a first communication module implemented by a first wireless communication technology and a controller determining that interference is generated by at least one of the first wireless communication technology or a second wireless communication technology and performing an operation to improve the generated interference, the second wireless communication technology implementing a second communication module provided in the terminal or in a different terminal.

First claim

What is claimed is:

1. A terminal, comprising:
a display unit displaying information;
a first communication module implemented by a first wireless communication technology; and
a controller determining that interference is generated by at least the first wireless communication technology or a second wireless communication technology and performing an operation to improve the generated interference by:
determining that interference is generated by the first and second wireless communication technologies if the first and second communication modules are provided in the terminal and both the first and second communication terminals are simultaneously driven;
selectively terminating either the first or second communication module and driving the non-terminated communication module; and
controlling the display unit to display information relevant to the generated interference, the displayed information comprising at least an announcement indicating that the selectively terminated communication module is available for driving.

2. The terminal of claim 1 , wherein each of the first and second wireless comprises at least one of WiFi®, WiBro®, WiMAX®, Bluetooth®, RFID®, or Zigbee®.

3. The terminal of claim 1 , wherein the information relevant to the generated interference comprises at least an announcement of the determined interference generation, information relevant to operations of the first and second communication modules or information related to selectively driving the first and second communication modules.

4. The terminal of claim 1 , wherein the controller further performs the operation to improve the interference by driving the selectively terminated communication module upon termination of driving the non-terminated communication module.

5. The terminal of claim 1 , wherein the controller selects to terminate either the first or second communication module according to significance of an operation performed by each of the first and second communication modules.

6. The terminal of claim 1 , wherein the controller selects to terminate either the first or second communication module according to a presence or non-presence of data transmission or reception for a predetermined period of time for each of the first and second communication modules.

7. The terminal of claim 1 , wherein the controller guarantees operation performance of each of the first and second communication modules according to significance of an operation performed by each of the first and second communication modules and the controller drives the first and second communication modules according to the corresponding guaranteed operational performance.

8. The terminal of claim 1 , wherein the controller determines that interference is generated by the second wireless communication technology upon searching for the second communication module if the second communication module is provided in the different terminal.

9. The terminal of claim 8 , further comprising:
an output unit outputting information relevant to the generated interference under control of the controller as part of the improvement operation.

10. The terminal of claim 9 , wherein the information relevant to the generated interference comprises at least one of an announcement of the determined interference generation, identification information related to the second communication module, or information related to selectively driving the first and second communication modules.

11. The terminal of claim 8 , wherein the controller delays driving the first communication module as part of the improvement operation and either indicates that the first communication module is drivable or drives the first communication module when the driving of the second communication module is terminated.

12. A method of improving interference in a terminal, the method comprising:
driving a first communication module implemented by a first wireless communication technology;
determining that interference is generated by at least one of the first wireless communication technology or a second wireless communication technology; and
performing an operation to improve the generated interference according to a result of the determination by:
determining that interference is generated by the first and second wireless communication technologies if the first and second communication modules are provided in the terminal and both the first and second communication terminals are simultaneously driven;
selectively terminating either the first or second communication module and driving the non-terminated communication module; and
displaying information relevant to the generated interference on a display of the terminal, the displayed information comprising at least an announcement indicating that the selectively terminated communication module is available for driving.

13. The method of claim 12 , wherein performing the operation to improve the generated interference further comprises driving the selectively terminated communication module upon termination of the driving of the non-terminated communication module.

14. The method of claim 12 , further comprising:
setting significance of an operation performed by each of the first and second communication modules; and
selecting to terminate either the first or second communication module according to the significance.

15. The method of claim 12 , further comprising:
determining a presence or non-presence of data transmission or reception for a predetermined period of time for each of the first and second communication modules; and
selecting to terminate either the first or second communication module according to the determination.

16. The method of claim 12 , further comprising:
setting significance of an operation performed by each of the first and second communication modules; and
guaranteeing operation performance of each of the first and second communication modules according to the significance,
wherein performing the operation to improve the generated interference further comprises driving the first and second communication modules according to the corresponding guaranteed operational performance.

17. The method of claim 12 , wherein the interference is determined as generated by the second wireless communication technology upon searching for the second communication module if the second communication module is provided in the different terminal.

18. The method of claim 17 , wherein performing the improvement operation comprises:
delaying the driving of the first communication module; and
indicating that the first communication module is drivable or driving the first communication module when the driving of the second communication module is terminated.
