Apparatus and a method for ciphering messages in mobile telecommunications system user equipment are disclosed. The apparatus is arranged to receive ciphering configuration parameters in a Radio Resource Control (RRC) layer; forward ciphering configuration parameters to a Radio Link Control (RLC) or Medium Access Control (MAC) layer; and, in response to subsequent receipt of a message from the network, which message indicates that the user equipment device is to start ciphering, configuring the user equipment device to start ciphering using the ciphering configuration parameters in the RLC/MAC layer.

Apparatus and a method for deriving a power measurement summation for use in universal mobile telecommunications system user equipment are disclosed. Conversion from a logarithm scale to a linear scale for summation and back again is avoided. The technique obviates the need for a mathematical processor to convert power measurements in a logarithmic scale (e.g. decibels dB, or dBw) into a linear scale (e.g. mW) to sum the power measurements or a ratio. The summed power component is calculated using data stored in the device (e.g. look up tables) without any need for conversion of the scale used.

Mobile user equipment for use in a cellular communications environment performs an improved cell selection on transitions out of a connected mode state. The transitions might be from one connected mode state to another or from a connected mode state to idle mode. The improvement in cell selection lies in assembling the list of candidate cells prior to cell selection. In the prior art, the list of candidate cells would usually be restricted to the serving cell or active cells supporting communication between the equipment and the network prior to transition. In embodiments of the invention, the list might comprise cells which are not the serving cell or which are outside the active set, for example a network-preferred cell or cells neighbouring the serving cell or cells of the active set.

The details of an apparatus and method for determining uplink ciphering activation time in universal mobile telecommunications system user equipment are disclosed herein. The ciphering activation time is determined for radio bearers other than RB2 by measuring the data rate on each target radio bearer during the time that it takes for a polling or RRC message sent from the user equipment UE to be acknowledged by the network UTRAN. For RB2, the uplink ciphering activation time is determined by taking into account the size of the RRC response message and the data already queued on RB2 for transmission.

Apparatus and a method for ciphering messages in mobile telecommunications system user equipment and network are disclosed. The apparatus is arranged to store a plurality of current ciphering configurations and/or a plurality of old (previously applied) ciphering configurations and/or a plurality of new (future) ciphering configurations. Thus different ciphering configuration may be applied at different times and for different radio bearers.

Apparatus and method for handling system information in mobile telecommunications system user equipment, wherein updates are applied in a defined order. In particular, in 3G UMTS systems, when System Information Block (SIB) SIB 11 and SIB 12 are received with information elements relating to cell information list (e.g. “intra-frequency cell info list”, “inter-frequency cell info list” and “Inter-RAT cell info list”) then the system information associated with the system information block information element in SIB 11 is applied before the system information associated with the system information block information element in SIB 12.
