下列对于伪导频的描述中,错误的是() A.伪导频硬切换需要进行异频搜索，但是由于时间较短，不会对通话质量造成大的影响B.PilotBeacon的导频强度可以准确的反映切换目标的导频强度，切换成功率高；而且该方法对各手机版本都支持。C.PilotBeacon不一定需要配置导频信道，但是一定要配置同步和寻呼信道D.PilotBeacon一定需要承担话务量E.设软切换目标激活集的强度为：ShoTargEcIo；设伪导频硬切换目标激活集的强度为：HhoTargEcIo；当BSC收到PSMM/PPSMM时，计算以上两强度；它们满足下面任意一项条件，即触发伪导频硬切换：{（ShoTargEcIo=T_ADD_HHO_PILOT_BEACON）（HhoTargEcIo=T_HHO_PILOT_BEACON_ABS_THRESH）}{（HhoTargEcIo-ShoTargEcIo）=T_HHO_PILOT_BEACON_REL_THRESH}
以下关于值班人员说法正确的是()。 A.值班人员在值班期间仅对所包维设备的正常运行和电路质量负责B.值班人员在值班期间要对全部设备的正常运行和电路质量负责C.如果包维设备人员在场，值班人员在值班期问对这些设备的正常运行和电路质量可以不负责
