A method and mobile device for performing wireless channel selection th at 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 devic e 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.
