Why it mattersThis helps ensure that mobile data connections remain stable and meet expected performance levels when users move between cell towers.

In the filing’s own words

The disclosure relates to a method and apparatus for monitoring and changing information about quality of service (QoS) allowed to be supported to a user equipment (UE) in a mobile communication system, and an operating method of a target base station (BS) in the mobile communication system includes receiving, from a source BS, alternative quality of service (QoS) profile (AQP) information, determining whether information matching QoS information allowed to be supported for a UE to be served is included in the AQP information, and when the information matching the QoS information allowed to be supported for the UE to be served is included in the AQP information, transmitting the matching information to an access and mobility management function (AMF).

What exactly they claim (claim 1)

1. An operating method of a policy control function (PCF) at handover from a source base station (BS) to a target BS in a mobile communication system, the method comprising: receiving, from a session management function (SMF), a notification related to a quality of service (QoS) information selected by the target BS among alternative QoS profile (AQP) information which is supported by the target BS; updating, a policy and charging control (PCC) rule based on the received notification; and transmitting, to the SMF, the updated PCC rule, wherein the QoS information selected by the target BS includes a value of at least one of a guaranteed flow bit rate (GFBR), a packet error rate (PER), or a packet delay budget (PDB).
