In plain words
TR 23.919 covers "deployment guidelines for the use of direct tunnelling of user plane data between the RNC and the GGSN". Direct Tunnel is an optional feature in Iu mode, allowing the SGSN to establish a direct user plane tunnel between RAN and GGSN within the PS domain. The SGSN handles control plane signalling and decides when to establish a Direct Tunnel. The report also highlights impacts of the 3GPP Release 7 solution on the current UMTS system. The newest version is V19.0.0, dated 2025-10-06.

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.
