Abstract
A core network element, such as a PCRF and/or an MME, can determine that a Quality of Service (QoS) Class Indicator (QCI) of particular bearer set up between the core network and user equipment (UE) should be changed to a new QCI. When a control node, such as the MME, determines that no teardown delay conditions are met, the control node can send a bearer release message to a base station that instructs the base station to tear down all bearers for the UE, even if they are in use. In a dual connectivity arrangement, such as a E-UTRAN New Radio-Dual Connectivity (EN-DC) configuration, the base station can instruct a secondary base station to also release all bearers for the UE. The control node can instruct the base station to reestablish the particular bearer with the new QCI when the base station reestablishes the bearers for the UE.
