If a gNB supports up to 64 UEs, will a new UE trying to establish a VoNR or emergency call be admitted based on the preemption method?

Hi Experts.

If the maximum supported UEs for a gNB is 64 & a new UE in the same area tries to establish a VoNR or emergency call beyond this limit, will it be admitted based on the preemption method?

Or Will preemption only work among the 64 connected UEs, releasing the bearer with the lower priority QoS?

If anyone has tested this or has insights, please share.

New high priority UE will get access the cell and One of UE will release (forcibly) from 64.

I have test this feature 4G all vendors.

Emergency will premempt lower prio arp VoNR user as per gNB policies.

Supported 64 UE is usually some O-RAN vendors.

Per cell 64 UE are generally default configurations.

So you are talking about preemption of bearers will work as well as in this case preemption of UEs will also work?

When new UE will be sending RRC setup request, based on established cause, gNB CU will take decision & release a low priority ARP UEs & new UE will be admitted?

Apart from ARP priority / PCI & PVI any other params will be will be playing role here?

This is based in CAC (Call Admission Control) algorithms.

It can be related number of UE, number of bearers (GBR and Non GBR) and so on.

It is proprietary algorithm.

If number of UEs is 64, and total number of bearers on each UE - 8 then total is 256 if any hand in happens what is the behaviour CAC algorithm defines.

If new VoNR comes then also it checks if low priority or high priority based on that pre emption happens based on priority defined else if incoming is emergency different implementation happens.
