A communication method, for use with a telecommunications system, enables special communications to be routed to respective devices in a group of the devices by addressing the devices with a respective special identifier. The telecommunications system includes a network core and a plurality of subscriber devices registered with the network core. The core enables communications to be routed to the devices by a respective ID allocated to each device. The method further includes maintaining a store of the special identifier of each device in the group and a corresponding value derived from the ID. The method enables the special identifier of a device in the group to be obtained from the store by providing the store with the corresponding value derived from that device's ID. |
