A method for use in a mobile telecommunications network, the mobile telecommunications network comprising a core network, a base station providing wireless connectivity within a base station cell, a mobile node in the base station cell providing wireless connectivity within a local cell and configured to communicate wirelessly with the base station, and a terminal (404D, 404E), configured to communicate wirelessly with the base station and configured to communicate wirelessly with the mobile node; the method comprising: defining a virtual cell tracking area that corresponds substantially to an area of wireless connectivity coverage of the local cell and, optionally, of one or more other local cells provided by mobile nodes in the base station cell, and has a unique virtual cell tracking area identifier which is associated with the base station and with no other base station, wherein the virtual cell tracking area identifier comprises a mobile country code identifying a country in which the mobile telecommunications network is located; a mobile network code identifying the mobile telecommunications network; a tracking area code identifying a paging procedure tracking area in which the base station is located; and a virtual cell tracking area code; notifying the core network of an association of the terminal (404D, 404E) with the virtual cell tracking area and the association of virtual cell tracking area identifier with the base station; sending a paging message for the terminal (404D, 404E) from the core network to the base station using the associations to direct the paging message to the base station, the paging message including the virtual cell tracking area identifier; and forwarding the paging message from the base station to the terminal (404D, 404E) using the virtual cell tracking area identifier, wherein when the terminal (404D, 404E) is associated with the virtual cell tracking area, it is not associated with any other tracking area. defining a virtual cell tracking area that corresponds substantially to an area of wireless connectivity coverage of the local cell and, optionally, of one or more other local cells provided by mobile nodes in the base station cell, and has a unique virtual cell tracking area identifier which is associated with the base station and with no other base station, wherein the virtual cell tracking area identifier comprises a mobile country code identifying a country in which the mobile telecommunications network is located; a mobile network code identifying the mobile telecommunications network; a tracking area code identifying a paging procedure tracking area in which the base station is located; and a virtual cell tracking area code; notifying the core network of an association of the terminal (404D, 404E) with the virtual cell tracking area and the association of virtual cell tracking area identifier with the base station; sending a paging message for the terminal (404D, 404E) from the core network to the base station using the associations to direct the paging message to the base station, the paging message including the virtual cell tracking area identifier; and forwarding the paging message from the base station to the terminal (404D, 404E) using the virtual cell tracking area identifier, wherein when the terminal (404D, 404E) is associated with the virtual cell tracking area, it is not associated with any other tracking area.
