Method and System with Separation of Session Anchor and Forwarding Anchor

A mobility management entity for a network including a mobile node that establishes a connection with a first network while in a second network and traverses to a third network comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions for:
• transferring location management information from the second network to the first network;
• establishing an indirection path from the first network to the third network for data packets directed to the mobile node;
• and
• transferring the data packets directed to the mobile node using the indirection path without traversing the second network.

A network comprising:

• a first network including a first access router, a first flow manager and a first location manager;
• a second network including a second access router, a second flow manager and a second location manager;
• and
• a third network including a third access router, a third flow manager and a third location manager;
• wherein, when a mobile device on the first network that has established a connection to a correspondent node on the second network moves from the first network to the third network, the location information for the mobile device is transmitted to the second network using the first and second location managers and the second network establishes an indirection path to the third network for communications between the correspondent node and mobile device using the second and third flow managers.

A first network comprising:

• a correspondent node;
• a first access router;
• a first flow manager;
• and
• a first location manager;
• wherein when a mobile device on a second network establishes a connection to the correspondent node and then moves to a third network, the first network uses location information for the mobile device from the first location manager to establish a flow for the connection between the first network and the third network wherein the flow does not traverse the second network.
