The present document describes the Diameter-based interfaces between the HSS and other network elements involved in the architecture for interworking with packet data networks and applications, such as Machine-Type Communications (MTC).
In particular, this document specifies the S6m interface between the Home Subscriber Server (HSS) and the MTC Interworking Function (MTC-IWF), the S6n interface between the HSS and the MTC-AAA and the S6t interface between the HSS and the Service Capability Exposure Function (SCEF). The procedures over those interfaces are defined in TS 23.682.

4.1 Introduction p. 9
The S6m reference point between the MTC-IWF and the HSS, the S6n reference point between the MTC-AAA and the HSS, and the S6t reference point between the SCEF and the HSS, are defined in the TS 23.682.
This document describes the Diameter-based S6m, S6n and S6t related procedures, message parameters and protocol specification.
An excerpt of the architecture for Machine-Type Communication, as defined in TS 23.682 is shown in Figure 4.1-1, where the relevant interfaces towards the HSS are highlighted.
In this architecture, the S6m reference point connects the MTC-IWF with the HSS, where the subscription information of the UE (e.g., an MTC device) is stored. This reference points allows the MTC-IWF to retrieve subscription data and to do any necessary mapping between different identities associated to the UE.
The S6m interface shall allow the MTC-IWF to:
- retrieve subscription information of the UE from the HSS,
- request routing information from the HSS, i.e. the address of the UE's serving nodes supporting SMS for the UE ; in this context serving nodes of the UE are the MSC or MME but not both, the SGSN, and the IP-SM-GW,
- retrieve the IMSI of the UE,
- retrieve the External Identifier of the UE associated to an Application Port Identifier,
- perform authorization of the Service Capability Server that is requesting to send a device trigger to the UE.
- configure UE related Monitoring events
- receive reporting of the configured Monitoring events from the HSS
- configure UE related AESE Communication Pattern
- Authorize the UE for NIDD.
