Abstract: 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.

Abstract: The details of an apparatus and methods of handling simultaneous universal terrestrial radio access network radio resource control procedures with activation times in a universal mobile telecommunications system user equipment are disclosed herein. According to one aspect, the apparatus includes a message handler to receive a received message from the UTRAN, a sequential processor to receive an ongoing command, a command store connected to the message handler to save the received command. The message handler determines if there is an existing command at the user equipment such that the user equipment appears to the UTRAN as though it were processing the select commands simultaneously while actually processing the existing command sequentially.

Abstract: A method and apparatus for taking measurements in a mobile telecommunications system is disclosed, the system comprising a network of a plurality of cells and at least one user equipment device. The user equipment device scans frequency bands to generate measurement data for signals received from cells of the network; and when the signals received from cells of the network include more than one signal in a frequency band, measurement data is generated for more than one signal in the frequency band.
Abstract: 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.

Abstract: In a mobile telecommunications system comprising a network of a plurality of cells and at least one user equipment device, the method comprises, in the user equipment device, when the user equipment has system information stored in the user equipment device, which system information has an associated expiration time limit, reading broadcast system information before the end of the expiration time limit and storing updated system information in the user equipment device.

Abstract: The details of an apparatus and method of uplink data during cell update in universal mobile telecommunications system user equipment are disclosed herein. According to one aspect of the present application, there is provided a user equipment to send uplink data to a UTRAN during a CELL UPDATE. The apparatus has an uplink data saving RRC with an uplink data store to save the uplink data while the CELL UPDATE procedure is ongoing, and a state machine having a Cell FACH state and/or a Cell DCH state. The uplink data saving RRC sends the saved uplink data to the UTRAN via an UPLINK DIRECT TRANSFER when the CELL UPDATE procedure has completed and the state machine enters either Cell FACH or Cell DCH state. According to another aspect of the present application, there is provided a method of sending uplink data to a UTRAN during a CELL UPDATE procedure.
Abstract: The present invention concerns a method for maintaining transparent mode radio bearers in a Radio Access Network (RAN) of a third generation mobile telecommunications network. The method relates to managing the radio resources allocated to a user equipment (UE) in said radio access network (RAN). The method generally comprises communicating a message from a radio resource controller (RRC) of the RAN to the UE where said message is arranged to instruct the UE to transition from a dedicated channel connection state to a lower activity connection state and to store in its memory transparent mode (TM) radio bearer (RB) information associated with said dedicated channel connection state. By storing TM RB information associated with the dedicated channel connection state, the UE can be reconfigured to the dedicated channel connection state without the RAN having to perform a radio bearer setup procedure.
Abstract: 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.

Abstract: The details of an apparatus and method of handling simultaneous universal terrestrial radio access network radio resource control procedures which change the security configuration in a universal mobile telecommunications system user equipment are disclosed herein. According to one aspect of the present application, there is provided a user equipment apparatus having a message handler, a sequential processor, a command store, and a security configuration change detector, wherein said message handler is coupled to said command store, is coupled to said sequential processor, and is coupled to said security configuration change detector to save, process, and detect configuration changes in commands respectively, and to determine if there is an existing command at the user equipment, such that the user equipment appears to the UTRAN as though it were processing commands simultaneously.
