RANtoCore

Delivering realistic test environments – from the RAN through the EDGE to the Core network

Fulfilling the potential of the evolving 4G and introduction of 5G will require an innovative and dynamic approach to network architecture in order to support all the proposed uses cases.

The industry is preparing to converge the Radio Access Networks (RAN) and the Core networks to bring processing functions and resources closer to the user, in order to reduce latency and traffic load, and increase bandwidth on the network.

Rigorous testing through the development phase of this new environment is vital to the success of commercial deployments. Our TM500 and TeraVM offers a complete end-to-end test solution from RANtoCore™, simulating real-world traffic and ensuring networks are robust enough to cope with the complexity and demands of devices and traffic at scale.

Only through the use of a complete end-to-end RANtoCore™ testing and validation solutions will you be able to gain a complete overview of the network and how it will perform under the demands of real-world traffic scenarios.

Use Cases

  • Resilience and Reliability: Connected Vehicles

    Ensuring the network is able to support the latency and reliability requirements for the connected car vision to become reality.

    Resilience and Reliability: Connected Vehicles

    Test Challenges

    • Latencies are critical – short latencies can help to increase traffic densities and speeds, longer latencies mean that vehicles must maintain a wider spacing to ensure sufficient “thinking time”
    • Using a conventional network architecture with a distributed and remote core network could add significant delays as well as large volumes of traffic through the network.
    • “Guaranteed service” – information such as braking to avoid a hazard is safety critical. The system can’t accept the equivalent of a dropped call.
    • Communications need to be secure. No risk of being hacked and e.g. accelerating when needing to brake.
    • Users in the vehicles will also be consuming other services e.g. video, voice calls. Edge-based context sensitive information may also be provided to the user. It is critical that such services do not impede the high priority/safety critical information that is essentially carried over the same RF link.

    Test Solution

    • Our solution can set-up varying user profiles to generate realistic data traffic for a live test on a massive scale
      A tailored solution to put your network to the test
      Scale on all levels: Number of User, Amount of Data, etc.
  • Security: Mobile Secure Gateway Performance

    Mobile traffic from the RAN to the core requires a secure connection to prevent cyber attacks on both the RAN and Core network.

    Security: Mobile Secure Gateway Performance

    Test Challenges

    • Creating a live test environment will prove time-consuming, complicated and costly – It’s unrealistic to create on a large scale
    • User profiles are varying – to set up sufficient profiles and generate realistic data traffic for a live test would be impossible
    • To implement this test scenario for every with thousands of live network eNB’s is not only unrealistic, it’s costly
    • The expectations to develop and execute new services quickly, means the validation procedure needs to be efficient and easy to roll-out for multiple sites
    • Testing is not just a one-off process – a developing network requires regular evaluation

    Solution

    • Use our validation solutions to create a real-world test environment in a lab or semi-live environment
    • Emulate secure RAN connection and populate each secure Ipsec pipe with mobile user data
    • A tailored solution to put your network to the test
    • Scale on all levels: Number of User, Amount of Data, etc.
  • Quality of Service: Radio Aware Video Optimization

    Delivering 4K video to consumers with confidence.

    Quality of Service: Radio Aware Video Optimization

    Test Challenges

    • Does the MEC video optimization really work under real world conditions and scale?
    • User profiles are varying – to set up sufficient profiles and generate realistic data traffic for a live test would be impossible to implement this test scenario for every with thousands of live network eNB’s is not only unrealistic, it’s costly
    • The expectations to develop and execute new services quickly, means the validation procedure needs to be efficient and easy to roll-out for multiple sites
    • Testing is not just a one-off process – a developing network requires regular evaluation

    Solution

    • Test engine generates variable UE traffic load with mix of real world voice, video, data apps.
    • TM500 causes/controls changes to eNB ‘channel quality indicator’ by means of different and variable radio conditions
    • Those changes should cause the MEC optimized video application to respond accordingly..
    • TeraVM can also supplement the real eNB setup with RAN emulation to stress multiple MEC server instances
    • Validates “end to end” video CDN with the combination of distributed user plane architecture and centralised control plane
