The main functions of the protocol are: - To allow the GMLC to request position estimates for a particular target UE from the MME or SGSN in order to support the EPC-MT-LR or PS-MT-LR positioning procedures. This is achieved using the Provide Subscriber Location message; - To allow the MME or SGSN to return a position estimate or an error report to the GMLC in response to a Provide Subscriber Location request as part of an EPC-MT-LR or PS-MT-LR positioning procedure; ETSI ETSI TS
