Abstract

A user communications device having active and idle states operates in a cellular communications network in which user communications devices communicate via network communications devices of cells of the network. History data identifying the cells in which the user communications device has camped whilst in the idle mode or identifying the cells in which the mobile device has been connected whilst in the connected mode is maintained. This history data can be used to identify a home base station.
