Abstract
A first radio base station (BS), a second BS and a core network (CN) node are provided, as are methods of operating the BSs and CN node when a first base station is to be replaced by a second BS. The first BS transfers to the second BS, information indicative of a BS state associated with the operation of the first BS; stops transmission to/from all wireless devices (WDs) to which the first BS is currently providing radio access; and transfers, to the second BS, information indicative of a plurality of WD states, a WD state being associated with a WD. The second BS then provides radio access to WDs, to which the first BS has hitherto provided radio access. The CN node can identify a need to replace a first BS; send a swap-in request to the first BS; and send a swap-out request to the second BS.
