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.
