Patent ID: 8676186

Claim:
A cell load balancing method, comprising: acquiring information of load of a current cell and information of load of an adjacent cell; determining a target cell in which a mobility parameter needs to be modified according to the information of the load of the current cell and the information of the load of the adjacent cell; sending a parameter modification request to the determined target cell; and performing a corresponding operation according to information indicating whether the mobility parameter is successfully modified and feedback from the adjacent cell; wherein the mobility parameter contains one or more of a cell handover parameter or a cell reselection parameter; wherein the acquiring the information of the load of the adjacent cell comprises: sending a resource status request message carrying an indication parameter to the adjacent cell, wherein the indication parameter is configured to indicate that the adjacent cell reports the information of the load if an event threshold is satisfied, or that the adjacent cell reports the information of the load if a report period is reached and an event threshold is satisfied; and receiving the information of the load sent from the adjacent cell; and wherein the sending the resource status request message to the adjacent cell comprises one or more of: sending the resource status request message through an interface with a node to which the adjacent cell belongs; transmitting the resource status request message through a mobility management entity (MME) to which the current cell belongs; transmitting the resource status request message through an MME to which the current cell belongs and a core network entity to which the adjacent cell belongs; or transmitting the resource status request message through an element management system (EMS) or a network management system (NMS).
