Method and system for supporting voice calls in 5G new radio environments

A method, comprising:

• providing, by a first wireless station with a first coverage area, a shared spectrum of a first frequency band, the shared spectrum including a first spectrum and a second spectrum;
• providing, by a second wireless station with a second coverage area, a third spectrum for a second frequency band, the second coverage area being at least partially within the first coverage area;
• broadcasting, by the first wireless station, a parameter barring an end device in an idle mode from camping on the second spectrum, wherein broadcasting the parameter includes broadcasting cell reselection 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
• triggering, by the first wireless station or the second wireless station, 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.

A non-transitory computer-readable medium storing instructions, which are executable by one or more processors, for:

• providing, by a first wireless station with a first coverage area, a shared spectrum of a first frequency band, the shared spectrum including a first spectrum and a second spectrum;
• providing, by a second wireless station with a second coverage area, a third spectrum for a second frequency band, the second coverage area being at least partially within the first coverage area;
• broadcasting, by the first wireless station, a parameter barring an end device in an idle mode from camping on the second spectrum, wherein broadcasting the parameter includes broadcasting cell reselection 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
• triggering, by the first wireless station or the second wireless station, 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.
