A1

Methods, apparatus and systems for data radio bearer management are disclosed. In one embodiment, a method performed by a first wireless communication node, includes: transmitting a data radio bearer (DRB) setup request message to each of at least one second wireless communication node, wherein the DRB setup request message contains the identity of a plurality of DRBs and at least one of a Quality of Service (QoS) flow and a UE bearer mapped to each of the plurality of DRBs, respectively; receiving a DRB setup response from each of the at least one second wireless communication node, wherein each DRB setup response contains a first list of at least one of QoS flows and UE data bearers failed to be setup by a respective one of the at least one second wireless communication node and a second list of at least one of QoS flows and UE data bearers successfully setup by the respective one of the at least one second wireless communication node; based on each of the first and second lists, determining at least one DRB and at least one QoS flow mapped to the at least one DRB supported by each of the at least one second wireless communication node; and configuring each of the at least one second wireless communication node to support the at least one DRB and the at least one QoS flow/UE data bearer.
