Abstract: The details of an apparatus and method are disclosed for ensuring that a traffic volume measurement message does not have a validity of CELL_DCH when the user equipment in a UMTS communications system is in CELL_FACH state. The validity is set to other than CELL_DCH at a UTRAN or the UE rejects a message having a validity of CELL_DCH when the UE is in CELL_FACH state.

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: In a mobile telecommunications system comprising a network of a plurality of cells and at least one user equipment device, the user equipment is arranged, when the user equipment re-configures itself to enter a new state or performs cell reselection, to read broadcast system information and, when the broadcast system information indicates a change in system information, to update the system information of the user equipment device.

Abstract: The details of an apparatus and method for handling cell update during reconfiguration in universal mobile telecommunications system user equipment are disclosed herein. When a UE receives a Reconfiguration request from a UTRAN, it sets an activation time for execution of the reconfiguration. Where a cell update is required before the reconfiguration has been applied, the UE cancels the reconfiguration and proceeds with the cell update.

Abstract: Apparatus and a method for handling discard of a service data unit in universal mobile telecommunications system user equipment. Strategies for the radio resource control entity to handle discard of a service data unit by the radio link control entity are presented.

Abstract: 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.

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 multi-mode mobile communication device may include a processing device, a memory sub-system, a communication sub-system operable to communicate with the plurality of wireless access networks, and a protocol stack stored in the memory sub-system and executed by the processing device. The protocol stack may include a first access stratum, a second access stratum, a non-access stratum and an access stratum manager. The first access stratum may communicate with a first wireless access network via the communication sub-system. The second access stratum may communicate with a second wireless access network via the communication sub-system. The non-access stratum may communicate with a core network. The access stratum manager may interface the non-access stratum with the first and second access strata, and may be operable to activate the first access stratum to establish a communication link with the core network over the first wireless access network.

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.
