This TS describes the Diameter-based SLh
interface between the GMLC and the HSS defined for the
Control Plane LCS in EPC.
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 TS 29.002
are mapped into the descriptions of the SLh Diameter commands.
