In plain words
TS 38.425 specifies NR user plane protocol functions used within NG-RAN and, for EN-DC and LTE UP-CP split, within E-UTRAN. It conveys "control information related to the user data flow management of data radio bearers". The functions may reside in nodes terminating X2-U (for EN-DC), Xn-U or F1-U, and support both E-UTRA PDCP and NR PDCP.

How this page was made
The facts box and the tables come straight from the 3GPP specification archive and CR database as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
