A load balancing system, comprising a first node and a second node, wherein:
- the first node is configured to executing the following operations:
- receive cell available resource information of a target cell of a second node from the second node, wherein the cell available resource information of the target cell comprises at least one of:
- an overlapping situation of the target cell with other cells in a frequency domain, an available resource of the target cell obtained by performing predetermined processing on an original available resource of the target cell according to the overlapping situation of the target cell with other cells in the frequency domain, an available resource of one or more beams in the target cell, and one or more beam identifiers of the one or more beams in the target cell;
- and
- perform load balancing according to the cell available resource information of the target cell of the second node;
- wherein the processor, when configured to execute the instructions to perform the load balancing according to the cell available resource information of the target cell of the second node, is configured to:
- send a handover request message with respect to selected User Equipment (UE) to the second node;
- and perform the load balancing according to a handover response message sent by the second node, wherein the handover response message comprises a handover preparation failure message or a handover preparation success message;
- wherein the handover response message is a message reported by the second node based on a comparison result obtained after comparing the cell available resource information of the target cell of the second node with the cell available resource information of the source cell of the first node;
- the second node is configured to executing the following operations before the first node perform the load balancing according to the handover response message sent by the second node:
- compare the cell available resource information of the target cell of the second node with the cell available resource information of the source cell of the first node;
- and
- send the handover response message to the first node according to a comparison result;
- wherein the processor is further configured to execute the instructions to:
- send an available resource request message to the second node before the first node receives the cell available resource information of the target cell of the second node from the second node, wherein the available resource request message is used for requesting the second node to provide the cell available resource information of the target cell of the second node;
- and receive an available resource request response message or an available resource request failure message sent by the second node;
- wherein the available resource request message carries one or more cell identifiers of one or more cells, for which the cell available resource information needs to be reported, in the second node, and configuration request information of the cell available resource information;
- wherein the configuration request information of the cell available resource information comprises at least one of:
- requesting to provide the overlapping situation of the cell with other cells in a frequency domain;
- requesting to provide cell available resource information obtained after considering the overlapping situation of the cell in the frequency domain;
- requesting to provide available resource information of one or more beams in the cell and one or more beam identifiers of the one or more beams in the cell.
