Abstract:
A device receives an emergency call via a session initiation protocol (SIP) invite that includes a cell identification (ID) and a service or device type associated with a user equipment (UE). The device determines, based on the service or device type, whether the UE is a fixed device or a wireless device, and uses a static approach to route the emergency call to a public safety answering point (PSAP) when the UE is a fixed device. The device uses a cell database to route the emergency call to the PSAP, based on the cell ID, when the UE is a wireless device.
