Mobile device geographic location determination for emergency services
11617059 · 2023-03-28 · ·

Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment and network nodes (e.g., eSMLC/LMF) to send multiple location responses instead of just one so that the PSAP can benefit from accurate location techniques in a timely manner. For example, when a user equipment is located in an outdoor environment, it can immediately send its A-GNSS location after meeting quality-of-service (QoS) criteria, and the eSMLC/LMF can forward the location estimate to the PSAP immediately without first waiting for all of the other location estimates. When location estimates become available from other technologies (e.g., E-CID, or DBH, or both), the eSMLC/LMF can send to the PSAP another location response for that technology. As a result, the PSAP can always have the most accurate and up-to-date location information available to timely and accurately respond to emergency calls.
