Abstract:
1. A method in an operations and maintenance (O&M) node for identifying a relay cell serviced by a relay radio node in a radio access network (RAN) of a cellular communications system in which there is a radio connection between the relay radio node and a donor radio base station, where the RAN donor radio base station is identified by a donor radio base station cell identifier, comprising the steps of: receiving the donor base station cell identifier from the relay radio node, determining a RAN relay cell identifier that uniquely identifies the relay cell within the RAN, the RAN relay cell identifier including a relay cell identifier and the donor base station cell identifier; and providing the RAN relay cell identifier to the relay radio node so that the relay radio node can transmit the RAN relay cell identifier to uniquely identify the relay cell to one or more radio terminals in the RAN.
