Patent ID: 8452285

Claim:
A method for communicating between a mobile station (MS) and a home agent (HA) in a wireless network that includes a first base station in a first subnet and a second base station in a second subnet, the first subnet being connected with the second subnet via a communication link, said method comprising: exchanging traffic between the MS and the HA along a first path, the first path being established via the first base station and a network entity operating as an anchor point in the first subnet; selecting at the second base station an intermediate anchor point for providing path information for access to the MS when the MS moves from the first subnet to the second subnet; establishing a second path for conveying traffic between said MS and said HA, said second path being established via said second base station, said intermediate anchor point, the communication link, and the network entity operating as an anchor point in the first subnet; and distributing topology and capacity related information to one or more network entities located in the second subnet enabled with routing capabilities.
