The present invention discloses a method, an apparatus and a system for acquiring load information. In one method, a source access controller and a target access controller can interact through inter-Radio Access Technology (RAT) handover related messages so that a source RAT system can acquire load information of a target RAT system when an inter-RAT Packet Switched (PS) handover is performed. This enables load balancing between different RAT systems so as to guarantee communications quality of the systems. In another method of the present invention, the source access controller and the target access controller interact through a Radio Access Network (RAN) Information Management (RIM) based load information request message and an RIM based load information response message, so that the source RAT system can acquire load information of the target RAT system before an inter-RAT PS domain handover is performed. This enables load balancing between different RAT systems so as to guarantee the communications quality of the systems. |
