5.1.1 Control Plane

5.1.1.1 HSS – MTC-IWF

Legend:

– Diameter: This protocol supports transferring of subscription and UE related information for identifier mapping and serving node information retrieval between MTC-IWF and HSS (S6m). Diameter is defined in RFC 3588 [15].

– Stream Control Transmission Protocol (SCTP): This protocol transfers signalling messages. SCTP is defined in RFC 4960 [16].

NOTE: It is up to stage3 to define interworking between diameter-based s6m and map-based interface to the legacy HLR.
