具体实施方式Detailed ways

本发明的核心在于确定触发基站功放保护后,在基站中关闭部分信道的发射功率,以降低基站功放功率实现基站功放保护,由于仅是关闭部分信道的发射功率,可以保证小区的覆盖不变,从而保证正常的通信不会中断,下面进行说明。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.

在某些情况下,基站功放能力有可能发生变化,如空调突然坏掉导致基站(NodeB)功放温度超过预定门限(即过温)时,则需要采取措施对基站功放进行保护,本发明中当检测到上述情况时可确定触发基站功放保护,实际触发基站功放保护的情况还有多种,由于不涉及本发明实质,这里不再赘述。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 protection of the base station. There are many situations in which the power amplifier protection of the base station is actually triggered. Since it does not involve the essence of the present invention, details are not described here.

为实现在基站中关闭部分信道的发射功率,本发明采用修改拥塞控制方式,参考图1,通过拥塞控制关闭部分信道的发射主要包括以下步骤:In order to realize the transmission power of closing some channels in the base station, the present invention adopts the modified congestion control mode, with reference to Fig. 1, the transmission of closing some channels by congestion control mainly includes the following steps:

步骤11,修改拥塞控制门限为预定值,所述预定值可以是一个较低的值(如正常情况下的拥塞控制门限的50%),即可使小区进入拥塞控制启动状态(因为此时小区功率还没有达到正常情况下的拥塞控制门限);Step 11, modifying the congestion control threshold is a predetermined value, and the predetermined value can be a lower value (50% of the congestion control threshold as under normal circumstances), that is, the cell can be made to enter the congestion control start state (because the cell is The power has not reached the congestion control threshold under normal conditions);

步骤12,在基站进入拥塞控制状态后,通过拥塞控制使非公共信道的发射功率逐步下降,同时公共信道功率保持不变,可达到降低基站功放功率的目的同时保证小区覆盖不变。Step 12, after the base station enters the congestion control state, the transmission power of the non-public channel is gradually reduced through congestion control, while the power of the public channel remains unchanged, which can achieve the purpose of reducing the power of the base station power amplifier and ensure the same cell coverage.
