Claim:
1. A method for route optimization during switching in an identity location separation architecture based on a network, comprising: establishing a communication relationship between a mobile node (MN) and a correspondent node (CN), switching, by the MN, from a source access network element to a target access network element, in which the target access network element stores a mapping relationship of identity information of the MN and location information of the target access network element; further comprising: inquiring, by the target access network element, to the MN to obtains identity information of the CN which has the communication relationship with the MN, and after the target access network element obtains the identity information of the CN, acquiring, by the target access network element, location information of an access network element on which the CN locates, and sending the mapping relationship of the identity information of the MN and the location information of the target access network element to the access network element on which the CN locates to update a mapping relationship on the CN from a mapping relationship of identity information of the MN and location information of the source access network element to the mapping relationship of the identity information of the MN and the location information of the target access network element.
