The present invention provides an information obtaining, information notification, data message forwarding and switch method and an access node during a terminal switch process. The access node comprises an opposite end information storage unit and a message transceiver unit, wherein, the opposite end information storage unit is set to store identification and locator mapping information of correspondent nodes of all accessed terminals; the message transceiver unit is set to: after establishing a connection with the terminal that switches to the local access node, receive a data message sent by the terminal to the correspondent node, according to the identification of the correspondent node in the data message, initiate an inquiry to a home ILR or an original access node of the terminal before switch-in to acquire and locally store the mapping information of the correspondent node, if the identification and locator mapping information of the correspondent node cannot be locally searched out. |
