How is Swiss telecom surveillance organised, and what is the role of the Dienst ÜPF?

The Dienst ÜPF (the federal Post and Telecommunications Surveillance Service) sits between the requesting authorities and the providers — it handles standardisation, operation, support & oversight, and statistics, routing authorities' requests to providers and returning the answers via a central processing system.

* Der Dienst UEPF als zentrale Vermittlungsstelle zwischen Behoerden und Providern. *

The three-party structure:

Authorities  ⇄  Dienst ÜPF  ⇄  Service Providers
(police, NDB)   (processing     (mainly Swisscom,
                 system)          Sunrise, Salt)

What the Dienst ÜPF does:

• Standardisation — defining uniform interfaces/formats for surveillance requests
• Operation (Betrieb) — running the central processing system that requests pass through
• Support & oversight (Aufsicht) — supporting and supervising the process
• Statistics — publishing surveillance figures (transparency)

The flow: authorities (police, the intelligence service NDB) send requests into the processing system; providers return their answers through the same system back to the authorities.

Why a central service? Rather than each police force negotiating directly with each telecom operator, a single state service standardises and brokers all requests. This gives uniform process, central oversight, audit trails, and consistent statistics — and spares providers from dealing with dozens of authorities ad hoc.

Go deeper:

• Dienst ÜPF — surveillance statistics (li.admin.ch) — the service's own published figures: how many real-time vs. retroactive measures, Antennensuchläufe, and information requests run per year — the "Statistics" task above, with the actual numbers.
