摘要:
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.

Air interface management apparatus for use in network-based control of measurements made by mobile user equipment with respect to cells of the network is adapted to detect conflict in content of measurement control messages instructing the report of pathloss measurement values. Conflict is detected in particular where the message specifies: a) an identity for a triggering event for which the category or categories of cell to be measured is determined at the receiver solely by said identity and comprises detected set cells, or b) periodical measurement in respect of a detected set cell. Pathloss measurements are not possible in these cases. The apparatus provides a mechanism for dealing with detected conflict by blocking transmission of, or response to, a measurement control message giving rise to conflict. Alternatively, the message or the response may be modified to avoid the conflict.

A method and apparatus for taking measurements in a mobile telecommunications system are disclosed, the system comprising a network of a plurality of cells and at least one user equipment device. The method comprises, at the user equipment device, receiving a measurement control set-up command and, in response the user equipment device, setting up the measurements. Then it monitors for a change in state of the UE and, in response to a change in state, issuing a measurement control pause command and, in response, the user equipment device stopping taking measurements, and maintains the measurement settings initialised previously. The device then monitors for a change in state of the UE and, in response to a change in state, issuing a measurement control resume command and, in response, the user equipment device resumes taking measurements with the maintained measurement settings.

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.

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.
