DS TS 129 336 V13.10.0:2018

Universal Mobile Telecommunications System (UMTS); LTE; Home Subscriber Server (HSS) diameter interfaces for interworking with packet data networks and applications (3GPP TS 29.336 version 13.10.0 Release 13)

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].
