In plain words
TS 23.548 defines Stage 2 specifications for enhancements of 5G System to support Edge Computing. Edge Computing enables operator and 3rd party services to be hosted close to the UE's access point of attachment. This supports efficient service delivery "through the reduced end-to-end latency and load on the transport network.". 5GS supports Edge Hosting Environment (EHE) deployed in the DN beyond the PSA UPF.

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.
