1. A method for communicating data between a correspondent node and a mobile node, the method comprising:
- receiving a home network prefix of the mobile node and a list of correspondent nodes by a mobile access gateway having an access link with the mobile node; and
submitting proxy binding update messages by the mobile access gateway to a home agent corresponding to the mobile node and to each of the correspondent nodes in the list, thereby creating a traffic path, between one of the correspondent nodes of the list and the mobile node, which goes through the mobile access gateway but bypasses the home agent.

12. A network node for providing a data link between a correspondent node and a mobile node, the network node comprising:
-
a processor in communication with a memory unit; wherein the processor receives a home prefix of the mobile node and a list of correspondent nodes having current sessions with the mobile node; and submits proxy binding update messages to a home agent corresponding to the mobile node and to each of the correspondent nodes in the list wherein the mobile node has an access link to the network node, thereby creating a data traffic path, between one of the correspondent nodes of the list and the mobile node, which goes through the mobile access gateway but bypasses the home agent. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A mobile node comprising:
-
a processor in communications with a memory unit; wherein the processor transmits identification of the mobile node and identification of a plurality of correspondent nodes currently having sessions with the mobile node to make available a home network prefix of the mobile node and the identity of the plurality of correspondent nodes to a mobile access gateway having an access link with the mobile node, thereby creating a data traffic path, between one of the plurality of correspondent nodes and the mobile node, which goes through the mobile access gateway but bypasses a home agent corresponding to the mobile node. - View Dependent Claims (20, 21, 22, 23)

24. A correspondent node comprising:
-
a processor in communications with a memory unit; wherein the processor, upon receiving a proxy binding update from a mobile access gateway, submits a proxy binding acknowledgement to the mobile access gateway, wherein the mobile access gateway has an access link to a mobile node, thereby creating a data traffic path, between the correspondent node and the mobile node, which goes through the mobile access gateway but bypasses a home agent corresponding to the mobile node. - View Dependent Claims (25, 26)
