<AcT> Integer type; access technology of the registered network
0 GSM (not applicable)
1 GSM Compact (not applicable)
2 UTRAN (not applicable)
3 GSM w/EGPRS (not applicable)
4 UTRAN w/HSDPA (not applicable)
5 UTRAN w/HSUPA (not applicable)
6 UTRAN w/HSDPA and HSUPA (not applicable)
7 E-UTRAN
8 EC-GSM-IoT (A/Gb mode) (see NOTES 5) (not applicable)
9 E-UTRAN (NB-S1 mode) (see NOTES 6)
<cause_type> Integer type; indicates the type of <reject_cause>
0 Indicates that <reject_cause> contains an EMM cause value
1 Indicates that <reject_cause> contains a manufacturer-specific cause value
<reject_cause> Integer type; contains the cause of the failed registration. The value is of type as
defined by <cause_type>.
<Active-Time> String type; one byte in an 8-bit format. Indicates the active time value (T3324)
allocated to the UE in E-UTRAN. The active time value is coded as one byte (octet 3)
of the GPRS Timer 2 information element coded as bit format (e.g. “00100100” equals
4 minutes). For the coding and the value range, please refer to the GPRS Timer 2 IE
in 3GPP TS 24.008 Table 10.5.163/3Gpp TS 24.008, 3GPP TS 23.682 and 3GPP TS
23.401.
Bits 5 to 1 represent the binary coded timer value.
Bits 6 to 8 defines the timer value unit for the GPRS timer as follows:
Bits
8 7 6
0 0 0 value is incremented in multiples of 2 seconds
0 0 1 value is incremented in multiples of 1 minute
0 1 0 value is incremented in multiples of decihours
1 1 1 value indicates that the timer is deactivated.
<Periodic-TAU> String type; one byte in an 8-bit format. Indicates the extended periodic TAU value
(T3412) allocated to the UE in E-UTRAN. The extended periodic TAU value is coded
as one byte (octet 3) of the GPRS Timer 3 information element coded as bit format
(e.g. “01000111” equals 70 hours). For the coding and the value range, please refer to
the GPRS Timers 3 IE in 3GPP TS 24.008 Table 10.5.163a/3GPP TS 24.008, 3GPP
TS 23.682 and 3GPP TS 23.401.
Bits 5 to 1 represent the binary coded timer value
Bits 6 to 8 define the timer value unit as follows:
Bits
8 7 6
0 0 0 value is incremented in multiples of 10 minutes
0 0 1 value is incremented in multiples of 1 hour
0 1 0 value is incremented in multiples of 10 hours
0 1 1 value is incremented in multiples of 2 seconds
