1. A system comprising:
a first wireless station with a first coverage area, the first wireless station providing a shared spectrum of a first frequency band, the shared spectrum including a first spectrum and a second spectrum; and
a second wireless station with a second coverage area least partially within the first coverage area, the second wireless station providing a third spectrum of a second frequency band,
wherein the first wireless station is configured to broadcast a parameter barring an end device in an idle mode from camping on the second spectrum, wherein the parameter further includes cell selection priorities to:
cause the end device in the idle mode to camp on the third spectrum when the end device is within the second coverage area, and
allow the end device in the idle mode to camp on the first spectrum when the end device is not within the second coverage area and is within the first coverage area, and
wherein the first wireless station or the second wireless station is configured to trigger the end device to switch to the second spectrum when a paging request for a voice call to the end device is detected or when the end device initiates a voice call.
