The present document describes the diameter-based Sc interface between Data Channel Signalling Function (DCSF) and Home Subscriber Server (HSS) and specifies:
- The interactions between the Data Channel Signalling Function (DCSF) and Home Subscriber Server (HSS) at the Sc reference point, including the procedures and signalling flows.
- The protocol specifications and implementations, including the diameter application, commands and message contents at the Sc reference point.

4 General Description p. 8
This document describes the Sc interface related procedures, message parameters and protocol specifications.
The procedures, message parameters and protocol are identical as for the Sc. See clause 5 for details.
In the Tables that describe the Information Elements transported by each Diameter command, each Information Element is marked as (M) Mandatory, (C) Conditional or (O) Optional in the "Cat." column. For the correct handling of the Information Element according to the category type, see the description detailed in clause 6 of TS 29.328.
