I have argued a few times now that it would make much more sense to be able to make access and core independent of each other. 3GPP 5G Standards already have a feature available from Release-16 onwards that enables this with 5G Core, Standalone networks.
We use our smart devices currently for voice and data communications. When we are indoor, many times the data goes over Wi-Fi. This is what tempted operators to move to WiFi for voice solution as well. Many operators are now enabling Voice of WiFi in their network to provide reliable voice coverage indoors.
While this works currently without any issues, when operators start offering new native services and applications, like XR over 5G, the current approach won't help. When our devices are connected over Wi-Fi at present, they are unable to take advantage of operator core or services. With access and core independence, this will no longer be an issue.
I gave a short (15 mins) virtual presentation at 5G Techritory this year. I argued not just for WWC but also looked at what 5G features have a potential for revolution. It's embedded below.
