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.
Claims20
A method, comprising:
- receiving, by a computing device and from a user equipment (UE) placing an emergency call, address information associated with the UE;
- performing, by the computing device and when the address information fails to include a global positioning system (GPS) location of the UE, reverse geo-coding of the address information to determine the GPS location of the UE;
- and
- storing, by the computing device, the address information and the GPS location of the UE in a database.
A computing device, comprising:
- a memory configured to store a plurality of instructions;
- and
- a processor configured to execute instructions in the memory to:
- receive, from a user equipment (UE) without global positioning system (GPS) functionality, address information associated with the UE placing an emergency call, wherein the address information includes at least a civic address of the UE,
- perform, when the address information fails to include a GPS location of the UE, reverse geo-coding of the address information to determine the GPS location of the UE, and
- store the address information and the GPS location of the UE in a database.
A non-transitory computer-readable medium having stored thereon sequences of instructions which, when executed by at least one processor, cause the at least one processor to:
- receive, from a user equipment (UE) placing an emergency call, address information associated with the UE;
- perform, when the address information fails to include a global positioning system (GPS) location of the UE, reverse geo-coding of the address information to determine the GPS location of the UE;
- and
- store the address information and the GPS location of the UE in a database.
