Location-Based Services

Belle enables specialists to use location-based services to determine if the Belle user is likely at home, enabling faster dispatch.

U-TDOA Technology

U-TDOA is the tracking technology that 911 operators use to locate people who call 911 with a cellular phone. U-TDOA is used to locate more than 5 million callers per month.

How Belle Uses U-TDOA

  1. If Belle users do not know their location when they press the call button in an emergency, the specialist will transfer the user’s call to 911. The specialist will wait on hold.
  2. The user will speak with 911 operators through Belle, and 911 operators will locate the user with U-TDOA tracking. When 911 has dispatched help to the user’s location, 911 will transfer the call back to the specialist.
  3. The specialist will stay on the call with the Belle user until help arrives.
