String type; N/A for NB-IoT
String type; N/A for NB-IoT
String type; one byte in an 8-bit format. Requested extended
periodic TAU value (T3412) to be allocated to the UE in
E-UTRAN. (e.g. "01000111" equals 70 hours).
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
1 0 0 value is incremented in multiples of 30 seconds
1 0 1 value is incremented in multiples of 1 minute
1 1 0 value is incremented in multiples of 320 hours
1 1 1 value indicates that the timer is deactivated
String type; one byte in an 8-bit format. Requested Active Time
value (T3324) to be allocated to the UE.
(e.g. "00100100" equals 4 minutes).
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
