Method and system for wireless channel selection by a mobile device

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.

1 . A method of wireless channel selection by a mobile device having first and second transceivers, the mobile device communicating with a wireless network, comprising:
 creating a first connection with the wireless network over a first channel using a first transceiver;   establishing a service between the mobile device and a remote point over said first connection;   selecting a second channel and tuning the second transceiver to the second channel;   requesting resources over the second channel, including requesting a second connection with the wireless network;   determining whether granted resources are adequate for supporting said service;   switching said service to said second connection; and   terminating said first connection.
