Problems solved by technology

Many of the mobile devices available today provide complex functionality far beyond simple voice communications.
This greater level of functionality, especially the receipt of real-time streamed data, presents particular quality of service issues.
A particular difficulty arises when the device roams from one network to another network of a different type.
Existing mobile devices may not be able to maintain the service being conducted over the call when the device switches the call to the new network.

Abstract

A method and mobile device for performing wireless channel selection that employs more than one concurrent level 2 interface to facilitate a level 3 handoff. The method and device maintain an active service over a first level 3 connection through a first transceiver, establish a second level 3 connection through a second transceiver, and then switch the service over to the second connection. To establish an appropriate level 3 connection, the mobile device may evaluate candidate channels against criteria associated with the active service to ensure quality of service can be maintained over the new connection or may adapt the active service to a candidate channel.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of U.S. patent application Ser. No. 10 / 789,435, filed on Feb. 27, 2004, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to wireless mobile devices and, in particular, to a method and system for wireless channel selection by a mobile device.BACKGROUND OF THE INVENTION[0003]Many of the mobile devices available today provide complex functionality far beyond simple voice communications. For example, many devices enable a user to access remote servers or sites over a public network, like the Internet. Some of these devices permit users to engage in Voice-over-IP (VoIP) telephone calls. Other devices allow users to receive streaming data from remote resources, such as streaming video or audio data.[0004]This greater level of functionality, especially the receipt of real-time streamed data, presents particular quality of service issues....
