Universal Mobile Telecommunications System (UMTS); LTE; Home Subscriber Server (HSS) diameter interfaces for interworking with packet data networks and applications (V11.0.0; 3GPP TS 29.336 version 11.0.0 Release 11)
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) and the S6n interface between the HSS and the MTC-AAA. The procedures over those interfaces are defined in 3GPP TS 23.682 [2].
