5G Innovation Spawns New Test Challenges

5G Innovation Spawns New Test Challenges

5G demands are inherently different than 4G, as it aims to address existing and emerging mobile network architecture requirements for consolidated services, greater scale, and lower latency communications.

5G value propositions:

  • Scale network resources with the ability to dynamically assign network functions to support new services or new slices serving different verticals or use cases
  • Manage costs through consolidated services and paving the way for a true multi-vendor implementation at each layer or function
  • Service flexibility with the ability to handle and to accelerate the service delivery to all stakeholders

The 5G Core introduces new protocols, service-based architecture, virtualization, and network slicing, among other things. The elastic nature of the 5G Core network creates new challenges for testing the core network elements, both in isolation and in end-to-end setups.

5G Network Slicing: Ensuring Successful Implementation and Validation

This webinar explains how to implement network slicing in 5G networks and provides best practices for validation. 

Simulate 5G UE behavior to validate the 5G Core
Service-Based Architecture

The 5G architecture is service-based and the interaction between network functions is represented in two ways.

Reference point representation shows the interaction between the NF described by point-to-point reference point (e.g., N4) between any two network functions (e.g., SMF and UPF)

Reference Point

Service-based representation is where network functions (e.g., AMF) within the control plane enable other authorized network functions to access their services.

Service-based representation



This webinar walks through initial use cases driving user plane function (UPF) deployment. It covers several critical aspects such as multi-access edge computing (MEC) and quality of service (QoS) enforcement per session and flow.


Validate 5G Core at Scale

Using IxLoad’s real-world subscriber modeling, testers do not need to be protocol experts to develop realistic test scenarios. From a single application, users can perform capacity tests, detail a device’s throughput, measure voice and video quality, and model a wide variety of mobility scenarios.


A multitude of test topologies are available, centered around node isolation, interface testing, or service validation.
