EPS LTE User Location Information (ULI) decoder

This utility supports decoding 133 108 EPS LTE ULI values. ULI is an EPS GTPV2 Specific Parameter Information Element (IE) Type encoded as specified in 133 108 Annex B.9 (which references ETSI TS 129 274). This utility supports decoding the extensible ULI IE with one to all eight ULI identity types in 129 274 V14.4.0 section 8.21.

Enter User Location Information octet string encoded to 133 108 (2 to 78 hexadecimal digits)
