In plain words

TS 29.571 specifies the stage 3 protocol and data model for common data types used or may be expected to be used by multiple Service Based Interface APIs. "Data types identified as common data types shall be defined in this Technical specification and should be referenced from individual 5GC SBI API specifications." V20.1.0 includes CR subjects on abnormal user plane traffic mitigation, New IMS Events, and Common Sensing Data Types. It also includes a data type for audio and video media on MDC2 interface, plus API version and External doc update.

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.
