Provided is a method for positioning a mobile terminal in an LTE system, wherein the method comprises: a serving cell/base station sends respectively resource reservation notification messages to multiple neighbouring cells/base stations thereof, to notify the neighbouring cells/base stations to reserve measurement resources for SRS measurement of a mobile terminal; the mobile terminal sends SRSs to the serving cell/base station and the neighbouring cells/base stations by using the measurement resources respectively, so that the serving cell/base station and the neighbouring cells/base stations perform SRS measurement; and the serving cell/base station positions the mobile terminal according to results of the SRS measurement. Also provided is a corresponding system. By means of the solution provided in the present invention, the mobile terminal may be accurately positioned without adding any device, without coordination of the network side, and without any additional network device, and the mobile terminal does not need to meet any extra functional requirement. |
