Help is On The Way! (as we speak)

The Location Retrieval Function (LRF) is responsible for retrieving the location information of a UE (User Equipment) that has initiated an emergency session. This allows emergency responders, for example, to know exactly where you are before they ask!

But what if you are using Wi-Fi calling? Where does the service provider get your location information from for them to correctly relay your call to the nearest emergency service? No worries, because Acom has the answer.

You Are Covered! (even on Wi-Fi)

In our LRF, it can correctly receive, translate and return location information to the IMS (IP Multimedia Subsystem) without any delay. It then guides the UE to make the correct call to corresponding emergency service closest to the user.

Of course, there are all kinds of magic happening in the background: data exchanging, decoding, processing... But we don't need to get into that. These heavy stuff all happen in the background seamlessly so we can provide help to those who are in need of help, ASAP.

It's (Not) Rocket Science!

If you really want to get technical, then here it is.
When a person calls for a emergency service using his mobile phone, which is attached to a Wi-Fi network:
  1. The P-CSCF identifies the emergency call and forwards the initial emergency invite requests to an E-CSCF.
  2. The E-CSCF then forwards the invite to Acom's LRF system.
  3. Acom's LRF returns the request to E-CSCF with a correct emergency number and guides the UE to that number.
  4. Job done. Everybody safe.
