Abstract: Disclosed in the present invention are a positioning method and apparatus, and a narrowband terminal, a system and a storage medium. The method comprises: on the basis of a preset algorithm rule, acquiring position information of a narrowband terminal and converting same into GPS coordinates, and sending the GPS coordinates to a server end by means of a narrowband GPS backhaul link. By means of the solution, in a scenario without a GPS signal, a narrowband terminal can still return GPS positioning data by means of a narrowband GPS backhaul link; since positioning information sent by means of the narrowband terminal is positioning data which has been processed by the narrowband terminal, the data volume of the positioning data is relatively small, thereby ensuring that the returned GPS positioning data does not become large; and since the air interface occupancy time is short when the GPS positioning data is returned by means of a narrowband GPS channel, the timeliness of positioning of an indoor narrowband terminal is improved. In addition, since the air interface occupancy time is short when the GPS positioning data is returned, normal voice and short message services are not affected.
