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. According to another aspect, there is provided a method of processing simultaneous commands at a user equipment having a security configuration, including the steps of: determining if there is an existing command at the user equipment; upon reception of a received command: suspending the existing command processing; determining if commands contain a security configuration change; and either rejecting the received command; or saving the received command prior to resuming the existing command; such that the user equipment appears to the UTRAN to be processing commands simultaneously.

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

A method and apparatus for processing a message in a mobile, telecommunications device. The method comprises: receiving a Cell Update Confirm (CUC) message; determining whether the device has an empty C_RNTI variable; when the device has an empty C_RNTI variable, determining whether the CUC message includes a new C_RNTI; when the CUC message includes a new C_RNTI and the CUC message would cause the device to enter a state which requires the UE to respond to the message before entering the state, carrying out at least one further step prior to entering the state.

Wireless telecommunication system

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 when the reconfiguration has not yet been applied, the UE delays the execution of the cell update procedure until after the reconfiguration has been applied. If the trigger which initiated the cell update procedure is no longer relevant, the cell update is unnecessary and may be cancelled.

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.

Apparatus and method for operating a communications device in a mobile communications network

A method and device for processing a message in a UE (user equipment) mobile telecommunications device. The UE device receives a CUC (Cell Confirmation Confirm) message and, in response, determines whether the UE device has an empty cell identifier variable. If so, The UE device then determines whether the CUC message includes a cell identifier and, if not, and if the CUC message would cause the UE device to enter a state that requires the UE device to respond to the message before entering the a next state, carrying out at least one further step such as setting INVALID_CONFIGURATION to TRUE in the UE device prior to entering the state.

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.

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. According to another aspect, the method includes the steps of: determining if there is an existing command at the user equipment; and if there is an existing command at the user equipment, processing the existing command prior to processing any received commands such that the user equipment appears to be processing commands simultaneously. According to a third aspect, the method includes the steps of: determining the current time (T); and determining that the first activation time (T) comes after the second activation time (T) if (T&#x3c;T) XOR (T&#x3c;T) XOR (T&#x3c;T).
