Abstract

A method of improving the receive sensitivity of satellite DMB (digital multimedia broadcasting) in a mobile communication terminal is disclosed, the method including: a) receiving the satellite DMB through a gap filler; b) checking the receive sensitivity of the satellite DMB; and c) performing a process of improving the receive sensitivity when the receive sensitivity is less than a predetermined threshold value. In addition, a method of improving receive sensitivity of satellite DMB is disclosed, the method including: a) receiving from a mobile communication terminal a control request message of transmission power of a gap filler repeating the satellite DMB; and b) controlling the transmission power of the gap filler based on the control request message to increase the receive sensitivity of the satellite DMB in the mobile communication terminal.

Claims

1. A method of improving receive sensitivity of satellite DMB (digital multimedia broadcasting) in a mobile communication terminal, the method comprising:

a) receiving the satellite DMB through a gap filler;

b) checking the receive sensitivity of the satellite DMB; and

c) performing a process of improving the receive sensitivity when the receive sensitivity is less than a predetermined threshold value.

2. The method of claim 1, wherein the operation c) comprises:

c1) acquiring ID of the gap filler when the receive sensitivity is less than the threshold value; and

c2) transmitting a message including the ID to a DMB center to request the DMB center to increase transmission power of the gap filler having the ID.

3. The method of claim 1, wherein the operation c) comprises:

c1) acquiring ID of the gap filler and information concerning a base station when the receive sensitivity is less than the threshold value; and

c2) transmitting a message including the ID and the information concerning a base station to a DMB center to request the DMB center to control a beam pattern of the gap filler having the ID to be directed to a communication area of the base station based on the information concerning the base station.

4. The method of claim 3, wherein the information concerning a base station is information concerning a base station sector.

5. The method of claim 1, wherein the operation c) comprises:

c1) acquiring ID of the gap filler and information concerning a position of a mobile communication terminal when the receive sensitivity is less than the threshold value; and

c2) transmitting a message including the ID and the information concerning a position of a mobile communication terminal to a DMB center to request the DMB center to control a beam pattern of the gap filler having the ID to be directed to the mobile communication terminal based on the information concerning the position of the mobile communication terminal.

6. The method of claim 5, wherein, in the operation c1), the information concerning a position of a mobile communication terminal is acquired using GPS (global positioning system).

7. A method of improving receive sensitivity of satellite DMB, the method comprising:

a) receiving from a mobile communication terminal a control request message of transmission power of a gap filler repeating the satellite DMB; and

b) controlling the transmission power of the gap filler based on the control request message to increase the receive sensitivity of the satellite DMB in the mobile communication terminal.

8. The method of claim 7, wherein the control request message includes ID of the gap filler.

9. The method of claim 8, wherein, in the operation b), the transmission power of the gap filler having the ID is increased.

10. The method of claim 7, wherein the control request message includes ID of the gap filler and information concerning a base station.

11. The method of claim 10, wherein the information concerning a base station is information concerning a base station sector.

12. The method of claim 10, wherein, in the operation b) , a beam pattern of the gap filler having the ID is controlled to be directed to a communication area of the base station based on the information concerning the base station.

13. The method of claim 11, wherein a beam pattern of the gap filler having the ID is controlled to be directed to the base station sector based on the information concerning the base station sector.

14. The method of claim 7, wherein the control request message includes ID of the gap filler and information concerning a position of a mobile communication terminal.

15. The method of claim 14, wherein, in the operation b) , a beam pattern of the gap filler having the ID is controlled to be directed to the mobile communication terminal based on the information concerning the position of the mobile communication terminal.
