Abstract

A method for controlling the transmitting power in a base station transceiver subsystem is provided. The method includes the steps of collecting and combining fault information from devices that provide factors affecting a call processing service, and determining the range of transceivers that should have blocked transmitting power based on the collected and combined fault information. The transmitting power of the determined range of transceivers is blocked by sending a message to a corresponding transceiver interface processor connected to each of a plurality of transceiver groups within the base station transceiver subsystem. The transmitting powers are normally transmitting by sending a message to the corresponding transceiver interface processor, when a fault ceases.

Claims

1. A method for controlling a transmitting power in a base station transceiver subsystem, comprising the steps of:

processing fault information pertaining to factors affecting a call service and updating a first buffer accordingly;

checking the first buffer to determine if the call service is possible and updating a second buffer accordingly;

determining which transceivers out of a plurality of transceiver groups should have blocked transmitting power based on the updated second buffer;

blocking the transmitting power of the determined transceivers; and

restoring the transmitting power, when a fault ceases.

2. The method of claim 1, wherein the blocking step blocks the transmitting power of the determined range of transceivers by sending a message to corresponding transceiver interface processor connected to each of a plurality of transceiver groups within the base station transceiver subsystem.

3. The method of claim 2, wherein the restoring step restores the transmitting power when a fault is solved by sending a message to the corresponding transceiver interface processor.

4. The method of claim 1, wherein the factors affecting the call processing service are selected from the group consisting of when a trunk between the base station transceiver subsystem and a base station controller is abnormal, when all channel element interface processors within a frequency allocator are abnormal, when an automatic gain controller within a subcell is abnormal, and when a low noise amplifier within the subcell is abnormal.

5. The method of claim 1, wherein the transmitting powers of all the transceivers are blocked, when all links of a trunk between the base station transceiver subsystem and a base station controller are abnormal.

6. The method of claim 1, wherein the transmitting powers of all the transceivers corresponding to a frequency allocator in which channel element interface processors are contained are blocked, when the channel element interface processors within a frequency allocator are abnormal.

7. The method of claim 1, wherein the transmitting powers of all the transceivers corresponding to a subcell in which an automatic gain controller is contained are blocked, when the automatic gain controller within the subcell is abnormal.

8. The method of claim 1, wherein the transmitting powers of all the transceivers corresponding to a subcell in which a low noise amplifier is contained are blocked, when the low noise amplifier within the subcell is abnormal.

9. A method for controlling a transmitting power in a base station transceiver subsystem, comprising the steps of:

collecting and combining fault information from devices that provide factors affecting a call processing service and updating a first buffer and using the updated first buffer to update at least a second buffer;

determining the range of transceivers that should have blocked transmitting power based on the collected and combined fault information by referring to at least the updated second buffer;

blocking the transmitting power of the determined range of transceivers; and

restoring the transmitting power, when a fault is solved.

10. The method of claim 9, wherein the blocking step blocks the transmitting power of the determined range of transceivers by sending a message to corresponding transceiver interface processor connected to each of a plurality of transceiver groups within the base station transceiver subsystem.

11. The method of claim 9, wherein the restoring step restores the transmitting power when a fault is solved by sending a message to the corresponding transceiver interface processor.

12. The method of claim 9, wherein the factors affecting the call processing service are selected from the group consisting of when a trunk between the base station transceiver subsystem and a base station controller is abnormal, when all channel element interface processors within a frequency allocator are abnormal, when an automatic gain controller within a subcell is abnormal, and when a low noise amplifier within the subcell is abnormal.

13. The method of claim 9, wherein the transmitting powers of all the transceivers are blocked, when all links of a trunk between the base station transceiver subsystem and a base station controller are abnormal.

14. The method of claim 9, wherein the transmitting powers of all the transceivers corresponding to a frequency allocator in which channel element interface processors are contained are blocked, when the channel element interface processors within a frequency allocator are abnormal.

15. The method of claim 9, wherein the transmitting powers of all the transceivers corresponding to a subcell in which an automatic gain controller is contained are blocked, when the automatic gain controller within the subcell is abnormal.

16. The method of claim 9, wherein the transmitting powers of all the transceivers corresponding to a subcell in which a low noise amplifier is contained are blocked, when the low noise amplifier within the subcell is abnormal.
