Handoff between cellular and enterprise wireless networks
First Claim
1. A mobile station, comprising:
- a first wireless interface operable to couple to a first wireless network;
a second wireless interface operable to couple to a second wireless network; and
a controller operable to negotiate a first wireless link with the first wireless network using the first wireless interface, to establish a communication session with a remote device using the first wireless link, to detect a session handoff trigger, to negotiate a second wireless link with the second wireless network using the second wireless interface in response to the session handoff trigger, and to invoke a private branch exchange feature to transfer the communication session from the first wireless link to the second wireless link.

Abstract
A mobile station includes a first wireless interface that can couple to a first wireless network, a second wireless interface that can couple to a second wireless network, and a controller. The controller can negotiate a first wireless link with the first wireless network using the first wireless interface and establish a communication session with a remote device using the first wireless link. The controller can also detect a session handoff trigger, negotiate a second wireless link with the second wireless network using the second wireless interface in response to the session handoff trigger, and invoke a private branch exchange feature to transfer the communication session from the first wireless link to the second wireless link.
