<p>A mobile telecommunications network comprising an operations and maintenance centre and a plurality of cells, each cell comprising a physical cell identifier (PCI), wherein some of the cells are fixed cells, 12, 14, and some of the cells are mobile cells, 26, 28. A first cell comprises an eNB operable to host an automatic neighbour relation (ANR) function, including a neighbour relation table (NRT). The eNB maintains, in the NRT, information regarding whether a neighbouring cell is fixed or mobile. The eNB is further operable to identify the operations and maintenance centre for a newly detected mobile cell and request that it changes the cells PCI if its PCI collides / conflicts with that of an existing cell in the NRT by initiating a PCI assignment algorithm. Also disclosed is a mobile relay node (MRN) that moves between cells in the network, operable to monitor PCIs of cells that it presently neighbours, wherein, if the relay node detects that its PCI conflicts with that of a neighbouring cell, the relay node is operable to change its PCI. An eNB may also prompt one of a first mobile relay node and a second mobile relay node to change their PCI.</p> |
