Abstract
By transmitting the Measurement cell identity (MCI), in addition to the PCI PLMN cell identity (PCI), in a request to a node, an MCI to PCI mismatch is early discovered by the node and reported to the source eNode B. The handover procedure can be aborted in an earlier stage, saving time and resources. The node can then also include information in the response to the source eNode B, which makes it possible for the source eNode B to blacklist MCIs and MCI to PCI combinations. This way faulty or faked MCIs or PCIs can be discovered already in the source eNode B, saving even more time and resources.
