Momentum Increasing for Stand-Alone 5G Networks: Heavy Reading
Momentum is growing behind the launch of stand-alone 5G networks, Heavy Reading analyst Ruth Brown said during a Light Reading webinar on service assurance Thursday. The wireless industry remains in a transitional stage, she said. Carriers are “very eager to…

start monetizing 5G” and offer “long-awaited advanced 5G services,” she said. “Operators are still working through this long investment cycle,” she said. Carriers feel increasing pressure to ensure they can monitor network operations and “respond dynamically, in real time, to service needs,” Brown said. Moving to the cloud will require service assurance changes and orchestration and life-cycle management, she said. Support “really needs to move to this dynamic, real-time model” and “we need to think about how we’re going to get there.” Brown said automation will be critical, but most carriers report they are already automating their networks. Providers' top priorities are tools for developing and testing software network functions and network diagnostics and the resolution of problems, she said. Cloud native and virtual networks are becoming “more normal” for carriers, said Mark Watts, a member of the Verizon technical staff. “We essentially look at each individual application and whether it fits into the cloud-native” environment, he said. Software-based applications are more nimble than legacy, hardware-based applications, he said, stressing the importance of testing. Verizon prides itself on its reliable network “and that starts with service assurance,” Watts said. “Software testing is … more and more important as we’re embarking on this cloud-native journey,” he said. “Ongoing monitoring” of the cloud-based system “continues to be a very high priority" for Verizon and operators across the globe, Watts said. As carriers introduce different hardware and software into their networks, interoperability is also critical to ensure “the longevity and ongoing reliability of the network,” he said. 5G slicing remains “a hot topic,” as is ensuring that the service offered through slices is automated and “supported more quickly and in a more nimble manner.” Slicing could offer increased security, better gaming, high-throughput or ultra-reliable services beyond what is typically available on Verizon’s network, he said.
