Embodiment 1
[0048] Such as figure 1 As shown, the embodiment of the present invention includes the following steps:
[0049] In step 101, the eNB judges whether the load balancing period is reached, and if so, proceeds to the next step;
[0050] Step 102, the eNB obtains the load status of the cell under its jurisdiction (hereinafter referred to as the cell) through the measurement module; and obtains the load information of the adjacent cell through the resource status report information of the adjacent cell sent by the base station of the adjacent cell;
[0051] Among them, such as figure 2 and image 3 As shown, the neighbor cell load information is obtained through the X2 interface.
[0052] see figure 2 , eNB1 sends a resource status request message (RESOURCE STATUS REQUEST) to the base station eNB2 to which the neighboring cell belongs;
[0053] eNB2 returns a resource status response message (RESOURCE STATUSRESPONSE) to eNB1
[0054] see image 3 , eNB2 sends a resource st...
Embodiment 2
[0070] Steps 201-205 are the same as steps 101-105 in Embodiment 1.
[0071] In step 206, the first embodiment is improved, and some UEs are selected according to service priorities, and measurement tasks are reconfigured for the selected UEs.
[0072] Steps 207-209 are the same as steps 107-109 in Embodiment 1.
Embodiment 3
[0074] In the second example, since the number of UEs selected according to the service priority is limited, even if the handover threshold is lowered, there may be no UE that can meet the handover condition. Implementation example three improves example two.
[0075] Steps 301-305 are the same as steps 101-105 in Embodiment 1.
[0076] Step 306, select some UEs according to the service priority, and reconfigure measurement tasks for the selected UEs;
[0077] Step 307, if the measurement report is not received within a short period of time, expand the set of UEs selected according to the service priority in step 306, or lower the handover threshold again, resend the measurement task, and repeat step 307 until the UE that meets the handover conditions is selected , to switch;
[0078] Step 308, waiting for the arrival of the next load balancing execution period.
[0079] It should be noted that in this embodiment:
[0080] 1. The switching threshold cannot be lowered too l...
