[0003] The inventors noted that in related technologies, only the number of active users and load conditions are used as the basis for load migration between two 100M carriers (cells), without considering the number of inactive users on a particular carrier (cell).

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] Figure 1 This is a flowchart illustrating a reselection policy adjustment method according to one embodiment of the present disclosure. In some embodiments, the following reselection policy adjustment method is performed by a reselection policy adjustment device.

[0038] In step 101, the load of the first operator's dedicated carrier is determined based on the PRB (Physical Resource Block) occupancy rate, the number of active users, the number of inactive users, and the number of RRC (Radio Resource Control) connections of the first operator's dedicated carrier.

[0039] In step 102, the load of the second operator's dedicated carrier is determined based on the PRB occupancy rate, number of active users, number of inactive users, and number of RRC connections of the second operator's dedicated carrier.

[0040] In some embodiments, using formula

[0041] Load_Capacity[i]=PRB_Ratio[i]+(ACTIVE_Num[i] / RRC_TotalNum[i])+α×(INACTIVE_Num[i] / RRC_TotalNum[i])

[0042] Calculate the load capacity (Load_Capacity[i]) of the dedicated carrier for either the first or second operator, where PRB_Ratio[i] represents the PRB occupancy rate of the dedicated carrier for either the first or second operator, ACTIVE_Num[i] represents the number of active users on the dedicated carrier for either the first or second operator, INACTIVE_Num[i] represents the number of inactive users on the dedicated carrier for either the first or second operator, and RRC_TotalNum[i] represents the number of RRC connections on the dedicated carrier for either the first or second operator. α is the weight, for example, α is 0.1-0.3. i = 0 represents the first operator, and i = 1 represents the second operator.

[0043] In step 103, the reselection strategy of the dedicated carrier load of the first operator and the dedicated carrier of the second operator is dynamically adjusted according to the size of the dedicated carrier load of the first operator and the dedicated carrier load of the second operator.

[0044] In the reselection strategy adjustment method provided in the above embodiments of this disclosure, the load of the operator's dedicated carrier is determined by utilizing the PRB occupancy rate of the operator's dedicated carrier, the number of active users, and the number of inactive users. This effectively predicts the occurrence of a sudden increase in carrier load, thereby effectively improving network resource utilization and user experience.

[0045] Figure 2 This is a flowchart illustrating a reselection policy adjustment method according to one embodiment of the present disclosure. In some embodiments, the following reselection policy adjustment method is performed by a reselection policy adjustment device.

[0046] In step 201, the load of the dedicated carrier of the first operator is determined based on the PRB (Physical Resource Block) occupancy rate, the number of active users and the number of inactive users of the dedicated carrier of the first operator.

[0047] In step 202, the load of the second operator's dedicated carrier is determined based on the PRB occupancy rate, the number of active users, and the number of inactive users of the second operator's dedicated carrier.

[0048] In step 203, it is determined whether the dedicated carrier load of the first operator and the dedicated carrier load of the second operator are both greater than a preset threshold.

[0049] If the dedicated carrier load of the first operator and the dedicated carrier load of the second operator are both greater than the preset threshold, then proceed to step 204; if the dedicated carrier load of the first operator or the dedicated carrier load of the second operator are not greater than the preset threshold, then proceed to step 205.

[0050] In step 204, the cell access prohibition indication in the NR broadcast message of the first operator's dedicated carrier is set to prohibit access, and the cell access prohibition indication in the NR broadcast message of the second operator's dedicated carrier is set to prohibit access.

[0051] For example, the cell access prohibition indication MIB->cellBarred = Barred in the NR broadcast message of the dedicated carriers of the first and second operators.

[0052] In step 205, it is determined whether the dedicated carrier load of the first operator is equal to the dedicated carrier load of the second operator.

[0053] If the dedicated carrier load of the first operator is equal to the dedicated carrier load of the second operator, then proceed to step 206; if the dedicated carrier load of the first operator is not equal to the dedicated carrier load of the second operator, then proceed to step 207.

[0054] In step 206, the cell access prohibition indication in the NR broadcast message of the first operator's dedicated carrier is set to not prohibit access, and the cell access prohibition indication in the NR broadcast message of the second operator's dedicated carrier is set to not prohibit access.

[0055] For example, the cell access prohibition indication MIB->cellBarred = notBarred in the NR broadcast message of the dedicated carriers of the first and second operators.

[0056] In step 207, it is determined whether the dedicated carrier load of the first operator is greater than the dedicated carrier load of the second operator.

[0057] If the dedicated carrier load of the first operator is greater than the dedicated carrier load of the second operator, then proceed to step 208; if the dedicated carrier load of the first operator is less than the dedicated carrier load of the second operator, then proceed to step 209.

[0058] In step 208, the cell access prohibition indication in the NR broadcast message of the first operator's dedicated carrier is set to prohibit access, and the cell access prohibition indication in the NR broadcast message of the second operator's dedicated carrier is set to not prohibit access.

[0059] For example, in the NR broadcast message of the first operator's dedicated carrier, the cell access prohibition indication MIB->cellBarred = Barred, and in the NR broadcast message of the second operator's dedicated carrier, the cell access prohibition indication MIB->cellBarred = notBarred.

[0060] In step 209, the cell access prohibition indication in the NR broadcast message of the first operator's dedicated carrier is set to not prohibit access, and the cell access prohibition indication in the NR broadcast message of the second operator's dedicated carrier is set to prohibit access.

[0061] For example, the cell access prohibition indication MIB->cellBarred = notBarred in the NR broadcast message of the dedicated carrier of the first operator, and the cell access prohibition indication MIB->cellBarred = Barred in the NR broadcast message of the dedicated carrier of the second operator.
