Abstract: A method for partial quantization to achieve full quantized model includes quantizing a plurality of weights and a respective activation function from each of a plurality of respective layers of an original Machine Learning Model (MLM) to generate a quantized MLM comprising a plurality of frozen quantized weights. The plurality of frozen quantized weights are extracted from at least one frozen layer of the layers of the quantized MLM. The plurality of weights are quantized from at least one updated layer of an updated MLM to generate a plurality of updated quantized weights. The respective activation function of the at least one updated layer of the updated MLM is quantized from a difference between the original MLM and the updated MLM, to form a respective quantized activation function. A new quantized MLM is generated from the frozen quantized weights, the updated quantized weights and the respective quantized activation function.

Abstract: During the handover, a source base station transmits a handover request message carrying a QoS flow-based QoS parameter and/or a RB-based QoS parameter to a target base station. The target base station performs the admission control in accordance with the QoS flow-based QoS parameter or the RB-based QoS parameter, and transmits back to the source base station a handover request response message including information of a QoS flow or RB admitted successfully or unsuccessfully. The target base station performs, in accordance with the received information of the QoS flow, a convergence operation on the QoS flows which have a same QoS requirement, and generates a convergence mapping relationship from the QoS flows to the RBs and a corresponding RB configuration parameter. In addition, the target base station transmits the information of the QoS flow having been admitted to a core network.
