Introduction to Measurement Events

Measurement events are used to measure packet loss and latency on the radio interface. Measurement events are the heart of 5G networks. They play an essential role in helping the network to serve a broad range of user needs while improving the user experience, thus making it possible to move toward new applications and services. The architecture enables measurement events to be scheduled, executed, terminated or modified according to all associated policies at different layers (e.g., radio, transport, etc.). Measurement events can be synchronous or asynchronous, i.e., they may be triggered periodically or on-demand. The Measurement Event is an important building block for a measurement application and can measure multiple metrics at the same time. A measurement event can be specified to be triggered by specific events and/or periodically, to sample various types of data, such as link characteristics, neighboring cell and UE information, mobility measurements, reporting network topology and routing path measurements. 

The 5G Measurement Event framework defines key measurement events in the 5GNR and other related specifications. These measurement events include: minimum downlink throughput and latency, maximum uplink throughput and latency, mean uplink throughput, mean downlink throughput, and mean packet drop probability. Measurement events are triggered by traffic to the eNodeB. They are generated in both uplink and downlink. The Measurement Event (ME) provides traceable data on the service performance experienced by a UE in relation to a corresponding reference. A ME is executed in a CELL ONLY mode (meaning no user plane), and it may include one or more measurement types such as Voice Quality, Channel State Information, and Timing Advance Value. Measurement Event (ME) is a mechanism for traffic engineering. Measurement events are used to collect measurement statistics such as Cell Loss Probability (CLP) or cell throughput, aiming to support special transmission scheduling algorithms or other useful scheduling mechanisms in addition to conventional RRM and RLM. Measurement events are parameters of interest in 5G networks, such as throughput and latency. The objective of measurement events is to gather information on the quality of services delivered to devices over the network.

5G Measurement Events

The 5G Measurement Events project is a multi-vendor solution for measuring the 5G devices, services, and networks that will be deployed starting in 2020. The focus of this event is on preparation of the radio interfaces to support measurements beyond the target bands defined in 3GPP. We will discuss during this presentation how these events may help to create new opportunities for development and innovation, as well as meet objectives around developing 5G innovation while ensuring coverage and reach requirements are met within an economically viable framework. The 5G Measurement Events are designed to help the research community build systems that can be used for evaluating new 5G technologies. The goal of these events is to verify and validate testbeds, measurement methods and tools developed by the research community. Measurement Events are an essential part of 5G communications, as they allow real-time monitoring and accurate reporting of the performance of the new mobile broadband systems. This paper describes the measurement events specification from a technical point of view, focusing on their applicability in 5G networks, along with describing their design choices and providing examples of how Measurement Event data can be generated for different use cases.

 5G Measurement Events are designed to accelerate the 5G standardization process, enabling device manufacturers and network equipment providers to better understand the impact of their solutions on the real-world environment. To date, many parameters have been identified for these events. This feature enables you to use this spreadsheet to track all needed measurement events, as well as their schedule and expected location. The milestones table provides a list of key dates for each event type in different regions worldwide."
