Core Network Tools
Free online core network tools for telecom engineers — decode cell identities and subscriber IDs, dimension 5G SA network slices, and look up LTE/5G bearer QoS mappings.
Decode 2G CGI, 3G CGI, 4G ECGI, and 5G NCGI hex strings. Extracts PLMN (MCC+MNC), LAC, CI, ECI, eNB-ID, NCI, and gNB-ID.
Decode any IMSI to extract MCC, MNC, country, operator name and MSIN. Auto-detects 2-digit and 3-digit MNC from the operator database.
Decode LTE Tracking Area Code (TAC), 5G NR 24-bit TAC and GSM Location Area Code (LAC). Build full TAI/LAI/RAI identities from MCC, MNC and area code.
Dimension 5G SA network slices (eMBB, URLLC, mIoT) — calculate UPF throughput, SMF session rate and AMF registration load per slice and in aggregate.
Look up 3GPP QCI (LTE) and 5QI (5G NR) bearer quality identifiers. Resource type, priority, packet delay budget, error rate and use case for all standardised values.
Decode any 15-digit IMEI or 16-digit IMEISV. Extracts TAC (Type Allocation Code), SNR, check digit with Luhn validation, and identifies the GSMA Reporting Body Identifier (RBI).
