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. 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.
