摘要： A method and system for realizing network switching, and a mobile node are provided. An LMA receives a PBU message from a second MAG, wherein the PBU message carries identifier information of the mobile node, the IP address of a first interface, and the IP address of the second MAG. The LMA checks in the stored BCE whether the identifier information of the mobile node and the IP address of the first interface exist. If the existence is checked, the LMA continually judges whether the Proxy Care-of-Address in the BCE is the same as the Proxy Care-of-Address in the PBU message. If they are different, the LMA determines that the connection of the mobile node is a switchable connection, and determines that the mobile node has the ability of address preservation, then sends the IP address of the first interface to the second MAG.

摘要： A method for avoiding resource being released mistakenly during tracking area update or handover process comprising: determining, by a target Mobility Management Entity MME, whether to use an old System Architecture Evolution Serving GW or to reselect a new Serving GW; if the target MME determines to select a new serving GW, notifying the original MME, the original MME sending a request for deleting bearer to the old Serving GW. The technical scheme of the present invention can avoid that the original MME will still send a request for deleting subscriber context to the old Serving GW when the target MME still uses the old Serving GW rather than selects a new one during tracking area update or handover process of the subscriber, which results in the appearance of a problem that the resource related to the subscriber in the old Serving GW is released mistakenly.
