As you can read from the readme and wiki, pycrate has an ASN.1 compiler ad runtime, which supports the 3G RRC protocol: https://github.com/P1sec/pycrate/wiki/Using-the-pycrate-asn1-runtime#the-umts-and-lte-rrc-protocols

Regarding 3G SIBs, I think they are splitted into segments before being transmitted. Therefore, you may have to reconstruct each SIB from its segments before being able to decode it. You need to read 3GPP TS 25.331, section 8.1.1.1.3, for this.
