Abstract
Various embodiments of apparatus, systems and/or methods are described for providing an in-service upgrading of software for a radio access network (RAN) radio unit (RU). The method includes directing traffic from user equipment to the first RU and a second RU that both reside on a first sector of a cell site. A software upgrade is received at the first RU, and the amount of traffic at the first RU is drained to the second RU so that the second RU handles the traffic for the first sector. When the traffic has been drained at the first RU, the software upgrade is installed in the first RU, and the first RU is rebooted.
