The Request type information element is also used to indicate that the MS is requesting connectivity to a PDN that provides emergency bearer services, or DN that provides emergency services or keep the connection that provides emergency services to which it has connected via non-3GPP access, or to keep the PDU session to which it has connected via 3GPP access or non-3GPP access. The Request type information element is coded as shown in figure 10.5.158/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.173/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The Request type is a type 1 information element.
