<stat>[
,[<t
ac>],[<
ci>],[<AcT>][
,[<cause_
type>]
,[<reject_cause>][
,[<Active-T
ime>],[<Period
ic-T
AU>]]]]
.
When <n>=4.The unsolicited result code will provide the UE with additional information for the Active
Time value and the extended periodic TAU value if there is a change of the network cell in E-UTRAN. The
value <n>=5 further enhances the unsolicited result code with <cause_type> and <reject_cause> when
the
value
of
<stat>
changes.

para

<AcT>,
<tac>

<ci>,
<cause_type>,
<reject_cause>,
<Active-T
ime> and <Perio
dic-T
AU> are prov
ided on
ly if av
ailable.
The read command returns the status of result code presentation and an integer <stat> which shows
whether the network has currently indicated the registration of the MT. Location information elements
<tac>
,
<ci>
and
<AcT>,
if
available,
are
ret
urned

MT
