scope:
The present document describes the Diameter-based SLh interface between the GMLC and the HSS defined for the Control Plane LCS in EPC.
LCS procedures over the SLh interface are defined in the 3GPP TS 23.271 [2].
This specification defines the Diameter application for the GMLC-HSS, SLh reference point. The interactions between the HSS and the GMLC are specified, including the signalling flows. As LCS procedures over the Diameter-based SLh interface are identical to the MAP-based Lh interface, the descriptions of the Lh MAP operations defined in the 3GPP TS 29.002 [3] are mapped into the descriptions of the SLh Diameter commands.
