In the present embodiment, current channel is the i.e. backward channel corresponding with forward channel of the channel of speaking for user, forward channel transmission power control bit information.In a trunked call, if system has been set up the shared channel of cluster under a plurality of communities, so only need to be in the forward channel corresponding with speaking user channel of the community, user place of speaking transmission power control bit information, and power control bit unnecessary in forward channel is weeded out, namely the reverse power control bit yield value of the forward channel of community, the non-user of speaking place is set to zero, transmission power control bit information not in the forward channel corresponding with non-speaking user channel.
So, while sending forward power control bit information in base station, first can be regularly or judge on schedule whether current area forward channel is that whether speaking user channel have calling user terminal.The reverse traffic frame that the judgement of speaking user channel can receive the user that speaks by base station bottom demodulation module judges, if the traffic frame having had, non-delete frame, can think that this channel is exactly speaking user channel.
The judgement of speaking user channel can also judge in the following way: by base station frame, select distribution module (SDM) to judge whether the link that backward channel is corresponding has been the link of frame, the forward channel corresponding to link of good frame is speaking user channel, and other channel is non-speaking user channel.
Through judgement, if when current channel is non-speaking user channel, the reverse power control bit yield value in the forward channel that this current channel is corresponding is set to zero, i.e. transmission power control bit information not in forward channel corresponding to this current channel.
And for speaking user channel, can be according to predetermined reverse power control bit yield value transmission power control bit information in the forward channel corresponding with current channel.Such as, when the current channel of judgement is speaking user channel, when forward channel informing base station bottom that can be corresponding at the link of good frame is write frame, power control bit gain (PCGAIN) value is raised as higher gain, in the user's forward channel of speaking according to predetermined reverse power control bit yield value transmission power control bit information.
