1. A wireless communication system, comprising: one or more base stations, and one or more user devices, UEs, wherein, when running a certain application, the UE is to communicate over a session, the session having associated therewith a current Quality of Service, QoS, profile, the current QoS profile selected form a plurality of different QoS profiles associated with the session,
wherein, in case of a certain event, the wireless communication system is to replace the current QoS profile for the session by a new QoS profile for the session, the new QoS profile selected from a subset of the plurality of different QoS profiles associated with the session,
wherein the certain event includes a handover, HO, or a conditional handover, CHO, from a source base station to a target base station,
wherein the subset of the plurality of different QoS profiles includes:
one or more first QoS profiles having a preference less than the current QoS profile, or one or more second QoS profiles having a preference higher than the current QoS profile, and
wherein the target base station determines if the current QoS profile can be provided by the target base station, and
if the current QoS profile cannot be provided by the target base station, the target base station uses as the new QoS profile a QoS profile selected from the one or more first QoS profiles,
if the current QoS profile can be provided by the target base station, the target base station determines if a QoS profile better than the current QoS profile can be provided by the target base station,
if a QoS profile better than the current QoS profile cannot be provided by the target base station, the target base station uses as the new QoS profile the current QoS profile,
if a QoS profile better than the current QoS profile can be provided by the target base station, the target base station uses as the new QoS profile a QoS profile selected from the one or more second QoS profiles.
