Abstract:
1. A method for use in a wireless data communications system in which an access terminal is configured to selectively communicate using a plurality of access technology types, the data communications system including a mobility anchor that stores a home IP address for the access terminal, the method comprising: establishing a plurality of IP data flows between the access terminal and the mobility anchor using a first access network that employs a first access technology type, with each data flow transmitted between the access terminal and the mobility anchor using the same IP address for the access terminal; detecting a flow mobility trigger condition; performing signaling between the access terminal and a core network associated with the first access network to set up a flow map at the mobility anchor, wherein the flow map indicates tunneling information for at least one of the IP data flows to be moved to a second access network; and responding to the detected flow mobility trigger condition, by moving at least one of the IP data flows, based on the flow map, to the second access network using the same IP address for the access terminal and using a second access technology type while maintaining at least another one of the data flows to the first access network using the first access technology type.
