On what basis priority (ARP) is assigned to a bearer during call admission control ?

Question

In one use case, I observed that MAC is constantly toggling between "in_sync" snd "out_sync" states. So, every-time MAC forwards this indication to L3 (e.g., to RRC first and RRC sending to RRM), it is sending RRC Connection Reconfiguration to that UE with CQI and SR configurations, with exactly same values.
The reason for the behavior at MAC is not yet clear to me. Maybe due to DRX configuration. But, it is sending out of sync indication to L3 as radio link failure is getting detected by MAC for uplink. Although, actually RLF has not happened.
So, my doubt is that L3 to send exactly same copies of RRC Connection Reconfiguration is how justified? As there is a long sequence of RCRs is going on and each message is being sent in around 5-6 seconds interval.

Allocation and Retention Priority parameter is stored in HSS at per UE subscription level. For example there are multiple users who want to subscribe the same service and there are different plan to experience different quality of service. In this case even all connections are being served by an APN but due to different subscription level network established bearers for all UEs with differ QoS parameters.
