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
First Claim
1. A method of operating an access terminal (AT) configured to participate in a communication session within a communications system, comprising:
- participating in the communication session supported over a first system associated with a first physical layer;
monitoring application-layer performance parameters associated with the communication session over the first system, wherein the application-layer performance parameters include an outage duration (OD) during which no application-layer media frames are successfully received at the AT and a media error rate (MER) of the communication session that is measured by a client application of the AT at an application-layer;
determining, based at least in part on the monitoring, whether to hand off the communication session from the first system to a second system associated with a second physical layer; and
selectively handing off the communication session from the first system to the second system based on the determining.

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.
