Abstract:
Embodiments are directed to an application-layer handoff of an access terminal from a first system of an access network to a second system of the access network during a communication session within a wireless communications system. In an embodiment, the access terminal sets up a communication session on the first system. A multimedia client measures application-layer performance parameters for the communication session supported by the first system, and determines whether to handoff the communication session to a second system based at least in part on the application-layer performance parameters. If the multimedia client determines to handoff the communication session to the second system, the multimedia client initiates the handoff and the communication session is transitioned to the second system.
