1.
3GPP TS 44.060
specifies the system information messages which give the information about
whether the serving cell supports EGPRS.
2.
3GPP TS 25.331
specifies the system information blocks which give the information about whether
the serving cell supports HSDPA or HSUPA.
3. 3GPP TS 44.018 [156] specifies the EC-SCH INFORMATION message which, if present, indicates
that the serving cell supports EC-GSM-IoT.
4. 3GPP TS 36.331 [86] specifies the system information blocks which give the information about
whether the serving cell supports NB-IoT, which corresponds to E-UTRAN (NB-S1 mode).
5. <AcT> field is fixed at 9 for NB-IoT product .
