Multi-mode mobile station and method of changing its network connectivity using a network acknowledgement
First Claim
1. A method of changing network connectivity for a multi-mode mobile station, said multi-mode mobile station including a first interface for communicating with a first wireless network using a first wireless access technology and a second interface for communicating with a second wireless network using a second wireless access technology, said method comprising:
- while said multi-mode mobile station has a first connection with said first wireless network, said first connection using said first interface and said first wireless access technology, said multi-mode mobile station;
(a) detecting a triggering event based on a location of said multi-mode mobile station;
(b) in response to said triggering event, powering up said second interface and checking for availability of said second wireless network;
(c) determining that said second wireless network is available;
(d) determining that said second wireless network is preferred over said first wireless network based on pre-set user preferences, wherein determining that said second wireless network is preferred over said first wireless network based on pre-set user preferences comprises determining that voice service is available via said second wireless network; and
(e) establishing a second connection with said second wireless network, said second connection using said second interface and said second wireless access technology, wherein establishing a second connection with said second wireless network comprises said multi-mode mobile station registering for communication services on said second wireless network;
said multi-mode mobile station receiving an acknowledgement signal transmitted by said second wireless network, said acknowledgement signal indicating successful registration with said second wireless network; and
in response to said acknowledgement signal, said multi-mode mobile station disabling said first connection and powering down said first interface, wherein disabling said first connection comprises said multi-mode mobile station de-registering from said first wireless network.

Abstract
A multi-mode mobile station includes a first interface for communicating with a first wireless network, such as a wireless wide area network (WWAN), and a second interface for communicating with a second wireless network, such as a wireless local area network (WLAN). While the multi-mode mobile station has a first connection with the first wireless network, the multi-mode mobile station establishes a second connection with the second wireless network. When the second connection is established, the second wireless network transmits an acknowledgement signal to the multi-mode mobile station. In response to the acknowledgment signal, the multi-mode mobile station disables the first connection with the first wireless network and powers down the first interface.
