1. A system for communicating with a mobile personal computing device, comprising:
- a home agent (HA);
a first network, coupled to the HA via an interconnecting network; and
at least a second network, coupled to the HA via the interconnecting network;
wherein a mobile personal computing device has a single Internet Protocol (IP) address and is served by all available networks in parallel, in order to maintain multiple connections to the HA, and the HA dynamically maintains a connection table with an entry for each of the available networks, such that;
the first network provides a first signaling path and a data path for an Internet Protocol session to the mobile personal computing device,the second network provides a second signaling path to the mobile personal computing device,the mobile personal computing device simultaneously supports both the first and second signaling paths to the first and second networks, andthe HA switches the data path for the Internet Protocol session from the first network to the second network when a predetermined condition occurs, but the switch does not interrupt or tear-down the Internet Protocol session for the mobile personal computing device.

12. A method for providing continuous access to an Internet, comprising:
-
coupling a first network between a mobile personal computing device and a Home Agent (HA) using the Internet; coupling at least a second network, between the mobile personal computing device and the HA using the Internet; and wherein the mobile personal computing device has a single Internet Protocol (IP) address and is served by all available networks in parallel, in order to maintain multiple connections to the HA, and the HA dynamically maintains a connection table with an entry for each of the available networks, such that; the first network provides a first signaling path and a data path for an Internet Protocol session to the mobile personal computing device, the second network provides a second signaling path to the mobile personal computing device, the mobile personal computing device simultaneously supports both the first and second signaling paths to the first and second networks, and the HA switches the data path for the Internet Protocol session from the first network to the second network when a predetermined condition occurs, but the switch does not interrupt or tear-down the Internet Protocol session for the mobile personal computing device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
