Communications system
First Claim
1. A method performed by a user communications device having active and idle states in a cellular communications network in which user communications devices communicate via network communications devices of cells of the network, the method comprising:
- in the user communications device;
maintaining history data identifying a location of the user communications device while the user communications device is in the idle state, wherein the history data comprises data relating to at least one of cell selection and cell reselection; and
providing data relating to the history data to a network communications device when the user communications device is in the active state,wherein in the active state, the user communications device includes a radio resource control (RRC) connection.

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 been present whilst in the idle state is maintained. This history data is used by the user communications device or by a network communications device to enable adjustment of cell selection/reselection parameters for the user communications device in the active state.
