[0051] In an embodiment of the present invention, the diversion strategy can be set according to actual conditions, and the set diversion strategy can be stored in the Packet Data Convergence Protocol (PDCP) layer of the gNB.

[0052] Step 104: If it is determined that no diversion strategy is stored, the parameter values ​​corresponding to the obtained multiple data flows are calculated to generate a weighted value.

[0053] Step 106: Calculate the weighted value to generate a weighted factor.

[0054] Specifically, through the formula Calculate the weighted value to generate the weighted factor, where P k is the weighted value, K is the number of groups of parameter values. As an optional solution, the value of K is 7.

[0055] Step 108: Determine whether the weighting factor is greater than a second set threshold.

[0056] In an embodiment of the present invention, a second set threshold can be set according to actual conditions. If the weighting factor is greater than the second set threshold, it indicates that the data flow is large and needs to be processed by the second base station; if the weighting factor is less than or equal to the second set threshold, it indicates that the data flow can be processed by the first base station.

[0084] Specifically, multiple current video download rates are combined into one group of video download rates, multiple previous video download rates are combined into another group of video download rates, and multiple next video download rates are combined into another group of video download rates, thereby forming multiple groups of video download rates, performing weighted calculation on each group of video download rates, and generating video download rate weighted values ​​corresponding to each group of video download rates.

[0085] Step 2094, determine whether the ratio of the current user number weighted value to the previous user number weighted value is greater than zero, if so, execute step 2096; if not, execute step 2098.
