Abstract
A UE may receive input indicating an attempt to place an emergency call. The UE may communicate with a first cellular network to connect the emergency call. The UE may generate a first SIP header, the SIP header including first location data indicating a first location of the UE. The UE may transmit the SIP header including the first location data via a user plane function of the first cellular network. While the emergency call is ongoing, the UE may disconnect from the first cellular network and connect to a second cellular network. The UE may communicate with the second cellular network to continue the emergency call. The UE may then generate a second SIP header including second location data indicating a second location of the UE. The UE may transmit the second SIP header including the second location data via the user plane function of the first cellular network.
