3gpp Release 9

Minimization of drive test coverage optimization

In this part the main focus on different use cases where MDT can be applied.

Minimization of Drive Test (MDT) specifies different ways to improve network efficiency by using UE measurement logs. The logs collection in UE can be periodic or event triggered (e.g Radio Link Failures).

To make the MDT process more efficient and provide adequate results, different use cases are defined.
