Problems solved by technology

[0003] At present, the protection of the base station power amplifier adopts the method of directly shutting down. For example, when it is detected that the base station power amplifier is overheated (that is, the temperature of the base station power amplifier exceeds the predetermined threshold), it is generally used to directly shut down the base station power amplifier for protection. Although this method can realize the protection of the base station The protection of the power amplifier, but it will have a great impact on the business, because when this method is adopted, the cell covered by the base station does not exist, and the normal communication will be interrupted

Embodiment Construction

[0028] The core of the present invention is to turn off the transmission power of some channels in the base station after determining to trigger the base station power amplifier protection, so as to reduce the power of the base station power amplifier to realize the base station power amplifier protection. Since only the transmission power of some channels is turned off, the coverage of the cell can be guaranteed. This ensures that normal communication will not be interrupted, which will be described below.

[0029] In some cases, the power amplifier capability of the base station may change. For example, when the temperature of the power amplifier of the base station (NodeB) exceeds a predetermined threshold (i.e. overheating) due to the sudden failure of the air conditioner, measures need to be taken to protect the power amplifier of the base station. In the present invention, when When the above situation is detected, it can be determined to trigger the power amplifier prote...

Abstract

The present invention discloses base station power amplifying protection method. It includes determining triggering base station power amplifying protection, closing part channel transmitting power in base station, for reducing base station power amplifying power to realize base station power amplifying protection. Closing part channel transmitting power can adopt modifying congestion control threshold and starting up congestion control to realize. The present invention also discloses relevant device. The present invention also discloses relevant device.

Description

technical field [0001] The present invention relates to base station technology, and more specifically, the present invention relates to a method and device for base station power amplifier protection. Background technique [0002] The radio frequency power amplifier capability of the base station is a factor that affects the capacity and coverage of the cell in the communication system. Usually in the wireless network planning stage, the power resources of the cell are comprehensively configured according to factors such as the power amplifier capability of the base station and the wireless environment. However, in some cases, the power amplifier capability may change. For example, when the radio frequency power amplifier of the base station (NodeB) is overheated, in order to avoid equipment damage, the power amplifier of the base station needs to be protected. [0003] At present, the protection of the base station power amplifier adopts the method of directly closing. T...
