<p>The present invention discloses a method for managing data messages during handover of mobile nodes, which is used in a network where the identity is separated from the location. Said method includes the following steps: when a mobile node performs the handover, a first access gateway equipment where a correspondent node (CN) of the mobile node (MN) is located transmits, according to a corresponding mapping entry of said MN stored in a mapping table of the first access gateway equipment, a received data message which is transmitted to said MN to a second access gateway equipment where said MN is located; said second access gateway equipment forwards said data message and the corresponding correspondent entry of said CN stored in a correspondent information table of the second access gateway equipment to a third access gateway equipment, wherein, the aging period of the mapping entries stored in said mapping table is T1, the aging period of the correspondent entries stored in said correspondent information table is T2, and T2>T1. The present invention ensures the normal communication between the MN and the CN during the mobility handover process of the MN and after the handover is finished.</p> |
