1. A method performed by a network apparatus in a wireless network, comprising:
receiving a scheduling request (SR) from a user equipment (UE) associated with a current cell for providing an uplink (UL) grant for uplink data transmission;
determining whether uplink resources for the uplink data transmission are available or not at the current cell in response to the SR;
in accordance with a determination that the uplink resources for the uplink data transmission are available at the current cell, transmitting an UL grant for allocating the uplink resources to the UE associated with the current cell,
in accordance with a determination that the uplink resources for the uplink data transmission are unavailable at the current cell:
predicting a UL congestion condition of the current cell by applying at least one machine learning to a plurality of parameters of the current cell including a service type provided by the current cell to the UE and a packet loss tolerance of the current cell;
identifying a target cell by applying at least one machine learning to a plurality of characteristics of each cell in the wireless network, wherein a predicted load of the target cell is lower than a predicted load of the current cell in accordance with the predicted UL congestion condition of the current cell; and
performing a handover of the UE from the current cell to the target cell in the wireless network,
wherein the plurality of characteristics of each cell in the wireless network includes handover success related information of a corresponding cell in the wireless network, a UL congestion condition of the corresponding cell in the wireless network, and a UE traffic data type at the corresponding cell in the wireless network.
