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.

Abstract: A method and system are proposed for establishing a requested connection between a source node and a destination node in a telecommunications network. The system and method are described in relation to a 3GPP network, but are applicable to other types of networks. The method includes generating a source application identifier for the connection within the source node, retrieving a source node identifier for the source node and transmitting the source application identifier and the source node identifier to the destination to provide a source connection identifier for the requested connection between the source node and the destination node.

Abstract: A relay communications system is described in which a base station receives a request from an MME that an overload procedure be started or stopped. The base station inserts the identity of the MME into the request and forwards the modified request to a relay node. The relay node then initiates or terminates the overload procedure in accordance with the request for mobile telephones which the MME that made the request serves, but not for mobile telephones which the MME does not serve.
