ABSTRACT:
A mobile user terminal402accesses a packet data network450through one or more of several network access points404–412. One or more control points432–440determines which network access point or points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are preferably several routers, each having an associated home agent418–420which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents422–430, which forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal.
