Section: 8.2.7.26 Non-3GPP NW policies
Content: The AMF shall not include this IE during a registration procedure over non-3GPP access. This IE is included if the network needs to indicate whether emergency numbers provided via non-3GPP access can be used to initiate UE detected emergency calls (see 3GPP TS 24.302[ Access to the 3GPP Evolved Packet Core (EPC) via non-3GPP access networks; Stage 3 ]  [16]). If this IE is not included then the UE shall interpret this as a receipt of an information element with all bits of the value part coded as zero. NOTE: In this version of the specification, this IE is applicable in case the UE is connected to a PLMN using an ePDG as specified in 3GPP TS 24.302[ Access to the 3GPP Evolved Packet Core (EPC) via non-3GPP access networks; Stage 3 ]  [16].
