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 (T1) comes after the second
activation time (T2) if (T
