5G Core Network Testing for Lab

Lab departments have the crucial task of validating services, network functions, or software updates before they are rolled out in the live network. This requires specialized tools that perform the necessary load, protocol, functional or negative tests over a wide range of interfaces.

SITE provides Core Network testing capabilities in lab testing mode to address the requirements of service design and dimensioning, load testing, regression testing, and more.  These capabilities can be combined with the E2E testing capabilities and create unique testing strategies such as application-level performance tests under load conditions, segmented network tests, or network function tests under isolation.

Application-Level service performance under load (use case example)

The SITE system combines Lab testing capabilities and E2E service assurance under one platform. This opens the possibilities for unique testing scenarios such as evaluating application-level performance under load.

This can be easily done by using radio or smartphone-based probes for service assurance and core network probes to emulate load traffic. Lab teams can now dimension the network and evaluate the required resources for various SLAs and scenarios.
Core network testing use case

Benefit from a set of network function validation or regression tests

SITE's Lab testing mode capabilities and the wide range of interfaces that it can emulate makes it the ideal tool for regression testing or network function validation. Lab teams can test a network function across all its functional interfaces, making sure that new vendors, and new software updates are validated thoroughly before moving into production.

The ability to integrate Core Network Tests with CI/CD pipeline tools makes this process fully automated. Once the new software is rolled out, the automated test cycle can be triggered via an API call and all the procedures will be executed as defined in the test plan.

5G Core Network testing for Proactive Service Assurance

Continuous service assurance and monitoring is critical in a live network and service degradations must be detected before they have a business impact. SITEs Next Generation Core Network testing provides insight into baseline network performance, on key core network interfaces, such as LTE S1 or 5G N2 and N3.

Combining high volume testing with detailed service level KPIs and using real subscriber profiles, it provides a method for operations teams to have a segmented view into service performance and easily distinguish between RAN and Core related faults or service degradations. Combined with SITEs Smartphone and Radio probes, the Core Network probes for service assurance provide an in-depth view into service performance during launch and operational phases.
  • Focused on subscriber level service assurance
  • Large number of use cases, e.g. data, browsing, video,
  • Voice, throughput, latency, etc.
  • Extensive application layer KPI
  • SIMMUX capabilities
  • Support for S1 LTE interface and N2/N3 5G interfaces

OPEX saving with Automation and Proactive service assurance

Testing, monitoring, and regression effort typically increases as new technologies, features or services are added to a network. Without automation, the overhead associated with these operational processes grows exponentially.

The operational effort can be reduced with a comprehensive automation strategy supported by a platform on which new use cases can be easily introduced. The flexibility of the SITE platform allows its users to easily onboard new services or technologies into their existing automation and testing processes, keeping the operational efforts to a minimum.  

Many Tier 1 Operators around the world have already shifted their testing methods toward automated testing solution in order to achieve high test quality in record time:
  • Meet your time-to-market and quality objective
  • Save OPEX 
Core Network testing use case

ARPU protection and cost scalability with proactive service assurance

Communication Service Providers must monetize on the new technologies and services that they introduce to sustain their investments. This is particularly important with services where customer experience is key, such as 5G. Typically testing and monitoring efforts peak around the time the service or technology is launched but taper off as they become mature. The cycle repeats with each new service technology.

Unfortunately, this approach creates gaps where CSPs do not have visibility into their network and service performance and are exposed to churn due to bad customer experience. Automation and proactive service assurance bridges these gaps with continuous insights into service performance, across all technologies.
