Abstract

A method and system to facilitate handoff of user equipment (UE) back to the same wireless network that was earlier serving the UE. When the UE is being served by a first wireless network and is going to be handed off to a second wireless network, the second wireless network may receive and store an identifier of the first wireless network. In turn, when the UE is going to hand off from the second wireless network (e.g., due to low signal strength or preference for another air interface protocol), the second wireless network may then transmit the identifier of the first wireless network to the UE, to cause the UE hand off back to the first wireless network rather than to some other network.
