Section: 10.5.5.37 Non-3GPP NW provided policies
Content: The purpose of the Non-3GPP NW provided policies information element is to indicate to the MS whether emergency numbers provided via non-3GPP access (see 3GPP TS 24.302[ Access to the 3GPP Evolved Packet Core (EPC) via non-3GPP access networks; Stage 3 ]  [156]) can be used to initiate UE detected emergency calls. The Non-3GPP NW provided policies is indicated by the network and sent with the ATTACH ACCEPT message or ROUTING AREA UPDATE ACCEPT message to the mobile station. The Non-3GPP NW provided policies information element is coded as shown in figure 10.5.5.37-1/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.5.37-1/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The Non-3GPP NW provided policies is a type 1 information element.
