Octet 4 carries the feature support bits for each of the CIoT optimization as follows:

– Bit 8 to Bit 3: Spare, for future use and set to 0.

– Bit 2 – SCNIPDN (SCEF Non IP PDN Support Indication): Indicates the support of SCEF Non IP PDN Connection as specified in clause 5.13 of 3GPP TS 23.682 [61]

– Bit 1 – SGNIPDN (Gi Non IP PDN Support Indication): Indicates the support of Gi Non IP PDN Connection as specified in clause 5.3.13.8.3.3 of 3GPP TS 23.060 [4], when set to ‘1’.

Editors Note: Need for conveying support for other CIoT optimizations is FFS.
