identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.

1 Scope
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 3GPP TS 23.682 [2].
