Abstract:
1. A method of enhanced non-optimized handoff of a device from a first network to a second network in a wireless communication system comprising: receiving a unique identifier associated with the device from the device operating on a first radio access system of the first network; fetching context information for the device based in part on the unique identifier from a second radio access system of the second network, wherein fetching comprises transmitting a vendor specific network control protocol (VSNCP) message for requesting the context information for the device from a high rate packet data (HRPD) serving gateway (HSGW) in the second radio access system to mobility management entity (MME) in the first radio access network; and mapping, at the second radio access system, the fetched context information to a context for the device to facilitate the non-optimized handoff of the device to the second network, wherein mapping comprises transforming an attribute of the fetched context information.
