Abstract
The invention relates to methods for enabling handover for Simple IP or Mobile IP in a CDMA2000 network. In one embodiment, the new PDSN (17) establishes contact with the old PDSN (16) to obtain information about its PPP
connection with the MN (11). The new PDSN (17) then sets up a tunnel between the PDSNs (16-17) and copies the PPP connection, while the old PDSN (16) dismounts its own PPP connection. The traffic now goes from the MN (11) to the new PDSN (17) that tunnels it to the old PDSN (16) that in turn forwards it through its old connection to the HA (20) or the backbone (22).
In a second embodiment, the new PDSN (17) contacts the old PDSN (16) to obtain information about the connections associated with the MN (11), and uses the information to copy the connections, while keeping contact with the old PDSN (16) to update the same information.
Also provided are systems and PDSNs (16-17) for carrying out the methods according to the inventions.
