ABSTRACT:
Method and system for performing handoff in wireless networks. According to an embodiment, the present invention provides a method for wireless communication. The method includes providing an access terminal that is configured to perform wireless IP communication. The method also includes providing a first wireless connection for the access terminal by a first access node. The method further includes providing a first network access for the access terminal by a first connectivity node. Additionally, the method includes obtaining a plurality of addresses for the access terminal. The plurality of address includes a first address and a second address. The first address is associated with a first priority level. The second address is associated with a second priority level. The method additionally includes storing the plurality address by a home agent. The method also includes initiating a handoff process for switching from the first connectivity node to a second connectivity node.
