3GPP ASN.1 API's
3GPP ASN.1 Application Programming Interfaces (API's) are pre-compiled and optimized C function libraries for encoding and decoding protocol messages defined within 3GPP standards documents
API's are available for ASN.1-based protocols for 5G (New Radio) (LTE-NR-RRC, E1AP, F1AP, NGAP, XnAP, NRPPa) and LTE (Long Term Evolution) (EUTRA-RRC, S1AP, X2AP, M2AP, M3AP).
