摘要： A heterogeneous network includes a terminal side and a network side. The network side includes an original PoA and handover candidate PoAs. The terminal side is used to select the handover candidate PoAs, initiate a media independent handover request, terminate a connection with the original PoA, and establish a connection with the handover candidate PoAs. The original PoA is used to terminate the connection with the terminal side according to the media independent handover request initiated by the terminal side. The handover candidate PoAs is used to establish the connection with the terminal side according to the media independent handover request initiated by the terminal side. A method for handover between heterogeneous networks initiated by the terminal side and the network side based on the 802.21 architecture is also provided, which improves the processing of the handover process.
