Access control• Determines which users are allowed to access the

cell and when they can try to access• Access Classes (0-9, 11-15 on USIM)1Admission control (and pre-emption)• Determines which users are served and the type

of service offered• ARP (Allocation and Retention Priority)2Traffic Prioritization (Scheduling)• Determines the quality of service (throughput and

latency) for the offered services in use• QCI (QoS Class Identifier)3

High priority based on Access Class 11–15 on U-SIMfor public safety

Access control / class barringHow it works

Commercial subscribers

PoliceHigh priority access treated like emergency call

Low priority access rejected by eNodeB

S-MVNO LTEnetwork

Overload situation

eNodeBtemporarily rejects low priority subscriber access to ensure service continuity
