UE data collection, reporting and event exposure is specified by 3GPP SA4. This page lists its specifications and what each covers.
The page covers Release 17 to Release 19. No Release 20 work item in the 3GPP work plan lists these specifications. The work plan lists TS 29.517, which these specifications build on, under the Release 20 work items AIML_CN_Ph2-CT and eNetAE20-CT; their scope is unverified (see Release history).
- Specified by: 3GPP SA4.
- Two specifications: TS 26.531 (architecture) and TS 26.532 (protocols and formats).
- By release: both are created in Release 17 by the EVEX work item, which TR 21.917 clause 15.6 relates to the SA2 work item eNA_Ph2 (UE data collection and event exposure to consumers such as the NWDAF). Release 18 adds immediate data report delivery instructed by the UE application, and ANBR-based network assistance data reporting. Release 19 carries the Release 18 content forward, with an update of the API info and externalDocs fields. The Release 19 Advanced Media Delivery work adds Common Media Client Data reporting in TS 26.512 (TR 21.919 clause 11.6).
- Built on: the 5G System as defined in TS 23.501, TS 23.502, TS 23.288 and TS 29.517, and, for the APIs, TS 29.510.
Specifications
The Release column is the release of each document's first version. Titles are each document's cover title; the last column summarises its Scope clause.
| Specification | Title | Release | Covers |
|---|---|---|---|
| TS 26.531 | Data Collection and Reporting; General Description and Architecture | 17 | A generic architecture for collecting and reporting data in the 5G System |
| TS 26.532 | Data Collection and Reporting; Protocols and Formats | 17 | The APIs, resource structures and data models for the collection and reporting of UE data by the Data Collection AF, for event exposure to network consumers |
TS 26.531 has the same clause structure in Release 17, 18 and 19. In the OpenAPI description of TS 26.532 (annex B.3), the API roots stay at /v1; from V18.2.0 (Release 18, June 2024) the CreateConfiguration operation (POST) is under /sessions/{sessionId}/configurations, where V17.3.0, V18.0.0 and V18.1.0 put it under /sessions/{sessionId}/configurations/{configurationId}. The resource URL in clause 6.2.4 (.../sessions/{sessionId}/configurations/) is the same in all of them.
