eCall Minimum Set of Data

MSD gives the PSAP context such as vehicle identity, trigger type, location and direction-related information at a high level. The operational point is not just data transport; it is whether call takers can see, trust and act on the data.

What it does

The Minimum Set of Data is the structured vehicle and incident information sent with an eCall.

MSD is a model for emergency data associated with a vehicle-originated call.

How it works

  • The vehicle prepares a standardized emergency data payload.
  • The payload accompanies the emergency call path.
  • PSAP tools decode and display actionable fields.

Key interfaces and protocols

  • Vehicle eCall system
  • Emergency call path
  • PSAP eCall decoder/display

Systems it interacts with

  • eCall
  • NG eCall
  • Additional data
  • PSAP
  • Recording

Common failure modes

  • Data decode failure
  • Location in MSD conflicts with network location.
  • Call taker does not recognize trigger context.
  • Recording misses associated data.

Implementation considerations

  • Train PSAP teams on MSD fields.
  • Test vehicle data display and retention.
  • Document how conflicting locations are handled.

Standards

  • European eCall standards
  • ETSI Plugtests references
