System and method for providing handover of a mobile IP terminal in a wireless network

A method for performing handover by a mobile node in a wireless network supporting a Mobile IP (Internet Protocol), comprising the steps of:

• sending, when handover is needed, a request for neighbor access router information to an access router currently communicating with the mobile node;
• and
• upon receiving the neighbor access router information from the access router currently communicating with the mobile node, performing handover to a target access router to which the mobile node will be handed over using the received neighbor access router information:
• wherein configuration information is delivered from the access router currently communicating with the mobile node to a neighbor access router if a predetermined update period has arrived;
• and
• wherein, if the predetermined update period has not arrived, the access router currently communicating with the mobile node determines if a configuration element is change, and delivers changed configuration information to the neighbor access router if the configuration element is changed.

A method for providing handover of a mobile node in an access router of a wireless network supporting a Mobile IP (Internet Protocol), comprising the steps of:

• exchanging access router information with a neighbor access router;
• and
• upon receiving a neighbor access router information request from the mobile node, delivering neighbor access router information to the mobile node;
• wherein the step of exchanging access router information with a neighbor access router comprises:
• delivering configuration information to the neighbor access router if a predetermined update period has arrived, and if the update period has not arrived, determining if a configuration element is changed, and delivering changed configuration information to the neighbor access router if its configuration element is changed;
• and
• upon receiving neighbor access router information, comparing the received neighbor access router information with corresponding neighbor access router information stored therein, and updating information on the corresponding neighbor access router if the comparison determines that the neighbor access router information has changed.
