3GPP (GSM only) 44-series — UE-to-Network Signalling Protocols – Stage 3
The technical specifications (TS) are displayed in blue, while the reports (TR) are shown in green.
TS that have been discontinued in earlier releases are indicated with a light blue color.
TR in the '9' range that have been stopped are highlighted in light green.
TS or TR with a yellow background indicate those updated (other than an automatic update to Rel-18 version after Rel-18 stage 3 freeze) at the latest Q1-2024 Plenary Meetings. The new ones are displayed with a single red dotted overline.
