Abstract:
1. A method for routing packets from a home agent to a user equipment through a first access network and a second access network, the method comprising: sending a first binding update message from the user equipment over the first access network to create a first binding cache entry at the home agent, wherein an identification of a first flow is included in (i) the first binding update message and (ii) the first binding cache entry, wherein the first access network is a home link; subsequent to sending the first binding update message, sending a second binding update message from the user equipment over the second access network to create a second binding cache entry at the home agent, wherein an identification of a second flow is included in (i) the second binding update message and (ii) the second binding cache entry, wherein the second access network is a foreign link; in response to sending the second binding update message, sending a third binding update message from the user equipment over the first access network to modify the first binding cache entry at the home agent, such that an identification of a third flow is included in (i) the third binding update message and (ii) the modified first binding cache entry, and such that a care-of address in the modified first binding cache entry is set to a dummy value to indicate that the third flow is to be forwarded to the user equipment via the home link; and receiving, by the user equipment from the home agent, (i) a first plurality of packets through the first access network based on the identification of the third flow and (ii) a second plurality of packets through the second access network based on the identification of the second flow.
