A method (10) of configuring a radio access network comprising a plurality of digital units, DUs, for processing digital baseband signals, and a plurality of radio cells, each configured to handle respective traffic and comprising a remote radio unit. The radio cells are arranged in a plurality of clusters; the radio cells within a cluster are configured for radio coordination. At least one of the DUs is assigned to at least one of the clusters. The method comprises steps: a. selecting at least one of the clusters to be moved from the assigned DU to a different DU (12); b. selecting a respective target DU for each selected cluster (14); c. moving each selected cluster by (16): i. transferring handling of new traffic from each radio cell to at least one respective temporary host radio cell (20), being one of said radio cells that does not comprise a part of the selected cluster, and disabling each radio cell in the selected cluster (22); ii. assigning the target DU to the selected cluster (24); and iii. enabling each radio cell in the selected cluster (26) and transferring traffic handling from each said temporary host radio cell back to the respective radio cell in the selected cluster (28); and d. disabling any of the DUs that are not assigned to any of the clusters (18). |
