Abstract
Methods, apparatus, systems and computer program products are defined that provide multiple bindings in a Mobile Internet Protocol (MIP) network environment. The multiple bindings that are established are independent of one another, such that a forward link binding is decoupled from, or otherwise does not affect, a reverse link binding and vice versa. Multiple reverse link-only bindings may be established within an active route set for an access terminal. Additionally a single primary binding may be established that provides a forward link binding and reverse link binding. At any point in time, the access terminal may maintain only one primary binding.

A method for establishing multiple Mobile Internet Protocol (MIP) bindings, comprising:
- setting up a reverse link-only binding through a first network entity for transmitting data from an access terminal;
- setting up a forward link binding through a second network entity for transmitting data to the access terminal, wherein the reverse link-only binding is set up independently of the forward link binding, and wherein the forward link binding comprises a primary binding through the second network entity that allows forward link and reverse link communications;
- transmitting data on the reverse link through the first network entity;
- receiving forward link data transmitted through the second network entity;
- moving the primary binding to a third network entity if quality of a link to the third network entity is preferred over a quality of a link to the second network entity;
- after moving of the primary binding to the third network entity, changing the forward link binding of the second network entity to a reverse link-only binding;
- and
- upon the access terminal entering an idle mode, setting up a signaling-only binding with an access gateway configured to cause the access gateway to discontinue forwarding of data to the access terminal, to remove all other signaling bindings, to change all primary bindings to reverse link-only bindings, and to notify the access terminal when data is available.
