How Network Slicing and QoS settings affect Admission Control in 5G?

Hi Experts.

Do you have a good explanation on Admission Control in 5G and how Network Slicing and QOS settings affect it?

Hi Experts.

How the Admission Control proccess for 5G SA networks work?

How the network elements deal with eMBB and FWA subscribers access since their data usage profiles are quite different and the first ones have mobility and the latter are static?

Even though FWA subscribers are usually static, they do have mobility services enabled and it’s quite normal to find mobility commands from one 5G cell to another or even between 5G-SA and 4G cells (NSA capable or not).

The operator will usually require a different APN for those FWA devices and might impose different rules for AMBR or other data parameters, but I don’t see why any mobility capability would be restricted, as cell coverage quality can change (except mobility to CS networks but those legacy NWs will probably not even be supported on the FWA device side).

For sure it would be possible to move.

But there is the idea in some MNOs here in Brazil to sell the mobility service (or nomadic service) as SVA.

Some MNOs are planning to implement a geofence for each user at the time of the subscription activation

They want to restrict the mobility to a 50m radius.

The problem is that FWA users will be always connected to the network while mobile subs (as the name implies) are always changing their serving cells.

So at some point the fixed and the mobile subs will be competing for resources.

Even though it is quite unlike to happen at the network launch it will occurs eventually.

I just want to understand how the 5G core deals with this situation.

Verizon has a patented method for geofencing FWA devices.

You can find their full mechanism on application US11510024B2.
