1. A method performed by a network node, the method comprising:
for a first time duration, serving a cell area by a first physical network node, the first physical network node using an identifier of a logical network node, serving the cell area by the first physical network node comprising sending at least one paging message to a wireless device;
at the end of the first time duration, ceasing to send the at least one paging message to the wireless device;
broadcasting that the first physical network node has ceased sending the at least one paging message to the wireless device;
for a second time duration, serving the cell area by a second physical network node, the second physical network node using the identifier of the logical network node, serving the cell area by the second physical network node comprising sending the at least one paging message to the wireless device; and
the first physical network node serving the cell area with a first frequency band and the second physical network node serving the cell area with a second frequency band.
