How do you ensure the new 3GPP functional elements will handle the scale of deployments expected before trying them out in the live network? How do you guarantee services will continue to operate without issue during the upgrade? The path to a smooth transition requires an investment in testing and validation that starts with the equipment manufacturers.
Simulating entire hybrid LTE/5G networks to see how a new platform performs is essential to building the confidence needed to move forward. Knowing that new protocols and functionality have been fully exercised, at scale, is a critical check point before touching the live network.
Finally, having real-time visibility into the performance of existing and new services, during this transition period and after, provides the assurance your operations team need to key your customer happy.
