Different needs for latency based on scope, project, use case...

Different standards involved

RAN topology of tomorrow

  • user plane

  • control-plane

  • m-plane

@Martin Skorupski Add modified slide set

Optimization on UE and/or service level



Structure of the latency use cases

  • Where to measure?

  • What is measured?

  • How is it measured?



Latency measurement

  • for user-plane

    • UE: ping 1.1.1.1 
      ... will measure IMCP through host 1.1.1.1

  • for control plane

    • UE: establish a new data connection
      measure the time between the request and the success response

  • for management plane

    • SMO: perform a well-defined SET operation
      measure the time until the VES message for configChange is recieved by DMaaP

    • SON use case
