RANtoCore

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

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.

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

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.

Delivering 4K video to consumers with confidence.

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
