Method and System for Positioning Mobile Terminal in LTE System

摘要

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.

1. 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 measurement resources which are for a mobile terminal to perform Sounding Reference Signal (SRS) measurement; the mobile terminal respectively sending 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 measure the SRSs; and the serving cell/NodeB positioning the mobile terminal according to results that the serving cell/NodeB and the neighbouring cells/NodeBs respectively measure the SRSs.
