At a glance

Version 20.1.0 makes the Policy Control Function (PCF) query of the Unified Data Repository (UDR) optional for Planned Data Transfer with Quality of Service (PDTQ) policies.

What changed

In technical specification (TS) 29.543, clause 5.2.2.2.2 covers retrieval of PDTQ policies for every application service provider (ASP). Version 20.0.1 said the PCF "shall invoke the Nudr_DataRepository_Query service operation" to retrieve those policies from the UDR. Version 20.1.0 instead says the PCF "may invoke the Nudr_DataRepository_Query service operation" to retrieve them. The stated scope remains all existing PDTQ policies for every ASP.

Clause 5.2.2.3.2 covers indication of a selected PDTQ policy after a consumer's Hypertext Transfer Protocol (HTTP) PATCH request. With one PCF deployed, the added text says "PDTQ policies can be locally stored in the PCF and the interaction with the UDR is not required". Our reading: the query step attaches no single-PCF condition to may, while the selected-policy clause states that case separately.

Change request (CR) 0029 lists ZTE, Nokia and Ericsson as joint sources. Its subject concerns making PCF-UDR interaction optional for PDTQ procedures. It is revision 2, category F, among four change requests incorporated in version 20.1.0. The other requests concern energy-based PDTQ provisions, PDTQ service corrections and warning notification updates.

How this page was made

Written with AI assistance from two versions of the specification indexed by 3GPP Scout and the 3GPP CR database. An AI model (GPT-6 Sol) drafted each sentence and named the source it rests on. Code checked every quote word for word against the stored source text, and the live check fetched each TDoc again before publishing. A second AI model from another company (Claude Opus 5.5) reviewed the page against the same sources. The 3GPP documents themselves govern.
