A near real time RAN intelligent controller (near-RT RIC) dynamically selects an AMF for a UE by receiving over an E2 interface with a CU an AMF selection request in connection with a UE; generating, in response to the AMF selection request, an AMF selection; and sending to the CU over the E2 interface the AMF selection to cause the CU to initiate NGAP signaling with an AMF identified in the AMF selection.

User equipments (UEs) may be scheduled by determining relative priorities of data radio bearers (DRBs), each DRB associated with a respective UE. A limit is established dividing radio resources available for allocation in the cell during a scheduling period into at least a first limited portion and a second remaining portion. According to the determined relative priorities: a) up to the first limited portion of the radio resources are allocated to only the DRBs that have a guaranteed bit rate (GBR), and thereafter b) the second remaining portion of the radio resources are allocated to only the DRBs which have not been fully allocated from the first limited portion. Schedules indicating this allocation are transmitted to the respective UEs. In carrier aggregation where each carrier aggregated cells has a respective plurality of DRBs, relative priorities for each respective plurality of DRBs are determined for each carrier aggregated cell.

Fair distribution of radio resources between guaranteed bit rate (GBR) and non-GBR data bearers

User equipments (UEs) may be scheduled by, in a cell, determining relative priorities of data radio bearers (DRBs), each DRB associated with an active UE. A limit is established dividing radio resources available for allocation in the cell during a scheduling period into at least a first limited portion and a second remaining portion. According to the determined relative priorities: a) up to the first limited portion of the radio resources are allocated to only the DRBs that have a guaranteed bit rate (GBR), and thereafter b) the second remaining portion of the radio resources are allocated to only the DRBs which have not been fully allocated from the first limited portion. In carrier aggregation the radio resources are allocated in turn in each different cell per step a) and thereafter in turn in each different cell per step b).

To schedule user equipments (UEs) in a scheduling period, for each of X cells in a carrier aggregation (CA) system relative priorities of data bearers are determined. Each data bearer is associated with a respective UE having buffered data and at least one of the UEs is a CA-UE that is allowed radio resource allocation to its associated data bearers in at least two of the cells. For each CA-UE, the buffered data of the CA-UE is distributed across those cells in which the CA-UE and its associated bearers are allowed resource allocation using a measure of total data throughput for each of those cells. For each of the X cells resources are allocated to the data bearers according to the relative priorities such that for each CA-UE the resources allocated to its associated data bearers across those cells are sufficient to carry the buffered data as distributed.
