At a glance

Change request (CR) 0020 corrects an application programming interface (API) name and annex reference in technical specification (TS) 29.570 version 20.1.0.

What changed

CR 0020 is a category F correction under the TEI20 work item, with Nokia listed as its working-group source. It is linked to document CP-262017 at CP-113, and its revised wording appears in version 20.1.0. In version 20.0.0, clause 6.1.2.1 says the "Nscp_ee API is contained in Annex A." In version 20.1.0, the clause instead says the "Nscp_EventExposure API is contained in Annex A.2."

Annex A.2 already carried the Nscp_EventExposure API title in version 20.0.0. Our reading: Clause 6.1.2.1 now identifies an existing subclause within Annex A, rather than a new location for the definition. Our reading: The older Nscp_ee wording identifies the API now named Nscp_EventExposure in that clause. Our reading: These naming and reference edits alone do not establish a change in API behavior.

Nokia's CR 0019 concerns correction of a notification uniform resource identifier (URI). Nokia's CR 0021 corrects table numbering and a table reference in clause 6.1.3.2.3.1. Huawei's CR 0022 concerns an API version and external document update.

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.
