Solver - for flexible, scalable testing of Mobile core and IMS networks

Solver is a high-performance load generation, stress and feature testing solution, spanning technologies all the way from 2G GSM, 3G UMTS, 4G LTE, IMS to 5G. Solver offers powerful, multi-protocol functionality and helps ensure smooth deployment and troubleshooting for the entire Mobile Core and IMS networks, or isolated nodes within the network. Proven in multiple deployments, it has won awards for its ease of use and advanced functionality.

Solver can also perform quality and performance testing on media and voice streams. It generates voice and video sessions, which can be delivered according to customised traffic patterns. The results can be analysed to benchmark quality.

By simulating traffic from the Radio Access Networks (RAN) or nodes within the Mobile Core/IMS, it helps CSPs and network equipment manufacturers to simplify performance analysis, assert control over their networks, manage upgrade projects, and confirm compatibility between equipment from different vendors.

Key features:

  • Single platform for multiple network technologies
  • 5G NSA/ SA options
  • Control and user plan separation
  • Full stack support for data application modelling
  • Integrate with your Telco Cloud
  • Control and User Plane separation
  • Mobility support (inter and intra RAT)
  • Objective voice MOS scoring
  • Easy to use GUI and automation support


Simulate multiple radio technologies and variable traffic patterns

Solver can simulate multiple radio network technologies and generate high traffic volumes for flexible load testing. This dramatically simplifies qualitative performance analysis for equipment manufacturers and CSPs. A wide range of traffic patterns, including voice, messaging and data applications, can be created to run simultaneously or in sequence in order to simulate real world traffic scenarios. The flexibility allows anything from manual testing of basic features to fully automated load testing to be performed.

Simulate core network technologies for node isolation testing

Solver can simulate different network entities in the Mobile Core and IMS networks, allowing for node isolation testing. By combining a number of different emulated network nodes, you can refine the system under test from the entire Mobile Core to a single network element, in simple steps.

The same concept applies to IMS networks. Solver’s advanced subscriber modelling, leveraging a full-stack UE implementation for each simulated subscriber, can be used for sophisticated measurements per network node.

Fully automated and integrated with Test Automation frameworks

Solver can be fully automated and integrated with Test Automation frameworks, fully aligned with telco cloud deployment programmes and agile, DevOps release cycles. It can also be deployed as VNF(s) into the NFVI, with support for OpenStack, KVM and VMware.

Solver adds value at every step, from launch to each enhancement, extension or upgrade, with rich automated regression test capabilities. The flexible simulation and load generation features ensure that products meet the reliability and scalability criteria that they must deliver from launch.

Solver can be rapidly deployed and is easy to use, which simplifies product validation cycles and reduces costs. Highly scalable, Solver ensures that peak performance thresholds can easily meet the most exacting requirements.
