Abstract:
1. A method comprising: while a wireless communication device (WCD) is operating under a first air interface protocol on a first frequency, the WCD detecting a threshold signal under a second air interface protocol, wherein operating under the first air interface protocol on the first frequency comprises operating in an active mode under the first air interface protocol on the first frequency; and responsive to the detecting, the WCD transitioning from operating under the first air interface protocol on the first frequency to operating under the first air interface protocol on a second frequency, wherein operating under the first air interface protocol on the second frequency comprises operating in the active mode under the first air interface protocol on the second frequency, wherein the WCD is served by a radio access network (RAN) under the first air interface protocol, and wherein the WCD transitioning in response to the detecting comprises (i) in response to the detecting, the WCD providing a notification to the RAN, (ii) the WCD receiving from the RAN, in response to at least the notification, a directive for the WCD to transition to operate on the second frequency channel, and (iii) responsive to the directive, the WCD transitioning to operate on the second frequency channel.
