Pre-Go-Live Service Stability

5G System Architecture

Redundancy Design

You should add extra parts to every part of your 5G system. Redundancy means you have backups if something breaks. This helps your network stay strong and always work for important services. You can use backup links, extra power, and more hardware. You can also use software backups in virtual systems. This way, your network does not stop if one thing fails. Redundancy is very important for mission-critical networks and business use cases. You need to plan for backups in the core, edge, and access parts. This helps e2e applications work smoothly and supports ultra reliable low latency communications. Making redundancy a main goal makes your network stronger and more stable.

Scalability

Your 5G system should be ready to grow fast. Scalability lets you add more users and data without slowing down. You can use different ways to make your network bigger and stronger:

• Network automation helps you control resources and keep services stable.

• Virtualization lets you add new services quickly and manage them easily.

• Small cells give more coverage and space in busy places.

• Spectrum optimization uses all the frequencies in the best way.

• Cloud-native architecture helps you grow and gives more power.

• AI and machine learning help you guess traffic and use resources better.

• Edge computing handles data near users and cuts down delays.

• Network slicing lets you run many networks on the same hardware.

• Programmable infrastructure helps you try new things and make money.

These ways make your network strong, reliable, and high quality. Your 5G system can handle important jobs and stay up as more people use it.

Testing Strategies

Functional and Performance

You need to test your 5G system before you start using it. These tests make sure your network is strong and works well. You do these tests:

• 5G UE tests check if devices talk to the network.

• Protocol conformance tests check if communication rules are followed.

These tests help you find and fix problems early. Passing all tests makes your network strong, tough, and always ready.

Interoperability

Your 5G system must work with gear from different companies. Interoperability testing is important for a strong and reliable network. The table below shows what you learn from these tests:

Interoperability testing helps e2e applications and keeps the network strong. You make sure everyone gets good service all the time.

Risk Assessment

Failure Points

You need to find weak spots in your 5G system before you start. Common weak spots are identity spoofing, data theft, network map leaks, message replay attacks, and weak encryption. The 5G SA Core is a big risk and can be the main weak spot in private 5G networks. Different vendors may have different quality, which can add risk. You also need to think about rules and laws. For example, 5G signals can mess with airplane radar, which is not safe. Finding and fixing these risks early makes your network stronger and safer.
