A first group of User Equipment (“UEs”) may be High Priority Access (“HPA”) UEs, and a second group of UEs may be non-HPA UEs. In response to triggering events, system broadcast messages and/or Radio Resource Control (“RRC”) release messages may be used to cause HPA UEs to connect to the priority cells, and may cause non-HPA UEs to connect to other (e.g., non-priority) cells implemented by the base station. ## Claims ### Claim 1 A device, comprising: one or more processors configured to: release one or more User Equipment (“UEs”), that are associated with a first access level, from a particular cell associated with a radio access network (“RAN”) of a wireless network, wherein releasing the one or more UEs includes: determining that a first communication session, associated with a first UE, is a non-emergency communication session, releasing the first UE based on determining that the first communication session is a non-emergency communication session, determining that a second UE associated with the first access level is engaged in an emergency communication session, and forgoing releasing the second UE based on determining that the second UE is engaged in an emergency communication session;
