ABSTRACT:
The invention relates to backing up a network element (NE) in a telecommunications system. The network element (NE) comprises at least two cluster nodes (A, B, C) that are redundancy units of each other. Each cluster node (A, B, C) contains virtual nodes (a1, a2, b1, b2, c1, c2). Pairs are formed of the virtual nodes (a1, a2, b1, b2, c1, c2) in such a manner that the first virtual node of the pair resides in the first cluster node and the second virtual node in the second cluster node. One of the virtual nodes in the pair is active and the other on standby. When a cluster node malfunctions, the virtual nodes of the pairs whose active virtual nodes reside in the faulty cluster node are interchanged by changing the standby virtual nodes to active and the active virtual nodes to standby.
