The ELP message set is applicable to the SLg interface between the MME and the GMLC and the Lgd interface bet
32、ween the SGSN and the GMLC. ELP is developed in accordance to the general principles stated in 3GPP TS 23.271 2. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified
33、by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.

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 re
