Minimization of drive test coverage optimization

2

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.

Tricks to Read and Understand 3GPP Specifications

14

3GPP specifications are backbone of 3G, IMS, HSPA, Enhanced UTRA technologies. To understand a certain aspect of a protocol stack or encoding of PDUs or to study deep into physical layer one need to understand the respective specifications.   The specifications are developed taking into consideration that they should describe the behaviors of certain layer but the implementations in most (more ..)

RRC Measurements Cheat Sheet
