Qci change via bearer release and reestablishment

A control node of a core network, comprising:

• one or more processors;
• a communication connection configured to connect to a base station over a control plane interface, wherein one or more bearers are set up through the base station between the core network and a user equipment (UE);
• and
• memory storing computer-executable instructions that, when executed by the one or more processors, cause the control node to perform operations comprising:
• determining that a particular bearer of the one or more bearers is to be modified from having a first Quality of Service (QoS) Class Indicator (QCI) to having a second QCI;
• determining whether any teardown delay conditions are met;
• in response to determining that no teardown delay conditions are met, sending a bearer release message to the base station that instructs the base station to tear down the one or more bearers for the UE;
• and
• causing the particular bearer to be reestablished by the base station with the second QCI when the base station reestablishes the one or more bearers for the UE.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors of a control node of core network, cause the one or more processors to perform operations comprising:

• determining that a particular bearer of one or more bearers set up for a user equipment (UE) is to be modified from having a first Quality of Service (QoS) Class Indicator (QCI) to having a second QCI;
• determining whether any teardown delay conditions are met;
• in response to determining that no teardown delay conditions are met, sending a bearer release message to a base station connected to the UE, wherein the bearer release message instructs the base station to tear down the one or more bearers for the UE;
• and
• instructing the base station to reestablish the particular bearer with the second QCI when the base station reestablishes the one or more bearers for the UE.
