Abstract: Embodiments of the present invention relate to a method and an apparatus for presenting an indoor traffic map. The method includes: sending, by a near-end unit of an indoor distribution system, a pseudo carrier to a polled remote unit according to a pre-established polling routing table; receiving operating data collected by the remote unit and a measurement report reported by the terminal; determining traffic map data of the polled remote unit; determining whether the traffic map data meets a traffic map presenting condition, and presenting an indoor traffic map when the traffic map presenting condition is met. In the present invention, remote units are polled sequentially by using a pseudo carrier and a polling routing table, operating data of the remote unit and a measurement report of the terminal are obtained as traffic map data, to perform representation of a traffic map.

Abstract: Embodiments of the present application disclose a passive intermodulation suppression method and a passive intermodulation suppression system. The method in the embodiments of the present application includes: obtaining, by using a target uplink controllable gain module, a first power Pt of an uplink signal sent by an antenna; obtaining a second power Pb of a signal that is output from an output port of a base station; configuring a target attenuation of the base station; and adjusting the initial gain value based on the target attenuation to keep a gain of the base station constant. According to the method described in the embodiments, the base station can maintain the target attenuation constant in a process of adjusting a gain of the target uplink controllable gain module, thereby reducing a PIM requirement of a passive intermodulation suppression system.
