A method for positioning a mobile terminal in an LTE system, comprising: a serving cell/NodeB respectively sending resource reservation notification messages to multiple neighbouring cells/NodeBs adjacent to the serving cell/NodeB, to notify the multiple neighbouring cells/NodeBs to reserve, for a mobile terminal, measurement resources through which the mobile terminal sends Sounding Reference Signals, SRSs; the mobile terminal respectively sending the SRSs to the serving cell/NodeB and the multiple neighbouring cells/NodeBs by using the measurement resources to enable the serving cell/NodeB and the neighbouring cells/NodeBs to perform SRS measurement; and the serving cell/NodeB positioning the mobile terminal according to results of the SRS measurement performed by the serving cell/NodeB and the neighbouring cells/NodeBs respectively; wherein the serving cell/NodeB positioning the mobile terminal according to the results of the SRS measurement performed by the serving cell/NodeB and the neighbouring cells/NodeBs respectively comprises: the serving cell/NodeB summarizing, after the neighbouring cells/NodeBs transfer the results of the SRS measurement to the serving cell/NodeB, the results of the SRS measurement performed by the serving cell/NodeB and the multiple neighbouring cells/NodeBs respectively; characterized by calculating a distance between the mobile terminal and the serving cell/NodeB and each distance between the mobile terminal and each of the neighbouring cells/NodeBs based on timing advance comprised in respective results of the SRS measurement performed by the serving cell/NodeB and the multiple neighbouring cells/NodeBs; and according to each pre-stored distance between the serving cell/NodeB and each of the neighbouring cells/NodeBs, respectively calculating each angle between the serving cell/NodeB and each of the neighbouring cells/NodeBs; and according to the distance between the mobile terminal and the serving cell/NodeB, each distance between the mobile terminal and each of neighbouring cells/NodeBs, and each angle between the serving cell/NodeB and each of the neighbouring cells/NodeBs, positioning the mobile terminal. a serving cell/NodeB respectively sending resource reservation notification messages to multiple neighbouring cells/NodeBs adjacent to the serving cell/NodeB, to notify the multiple neighbouring cells/NodeBs to reserve, for a mobile terminal, measurement resources through which the mobile terminal sends Sounding Reference Signals, SRSs;
