Release 20
The work plan of 28 September 2026 lists no Release 20 work item for TS 26.531 or TS 26.532. It lists work item AIML_CN_Ph2-CT ("CT aspects for Core Network Enhanced Support for Artificial Intelligence (AI) / Machine Learning (ML) Phase 2", CP-262196, 90% complete, finish 3 March 2027) against TS 29.517, TS 29.510 and TS 29.522; TS 29.517 is the Application Function Event Exposure service that the Data Collection AF realises. The work plan also lists TS 29.517 against work item eNetAE20-CT (UID 1110017, "Rel-20 Enhancement of Network Automation Enablers", CP-260170, 60% complete, finish 3 March 2027). The scope of these work items was not read in a primary source and is unverified. The change history of TS 29.517 V20.1.0 records Release 20 change requests on abnormal user plane traffic information (CR 0168, CR 0174, CR 0177); it does not name the work item for them.
Two further Release 20 work items of the work plan of 28 September 2026 concern collection and reporting of application energy consumption information: Energy_ARCH-MED (UID 1120097, system architecture for application energy consumption information collection and reporting, Stage 2, 100% complete, finish 9 September 2026, SP-260418; it lists TS 26.501, TS 26.506, TS 23.367, TS 33.367) and Energy_PRO-MED (UID 1130006, protocols, network APIs and data types for application energy consumption information collection, reporting and exposure, Stage 3, 0% complete, planned 3 March 2027, SP-261003; it lists TS 26.527, TS 26.113, TS 26.510, TS 26.512). Only Energy_PRO-MED lists TS 26.512. Their relation to TS 26.531 and TS 26.532 is not stated in the work plan.

What the release descriptions add:
- 5GMS_Pro_Ph2 (TR 21.918 clause 17.9) lists the specification of data types for data reporting of ANBR-based Network Assistance invocations and, in liaison with CT3, of data types for exposure of events relating to invocation of AF-based and ANBR-based Network Assistance; it names TS 26.532 among the updated specifications.
- 5GMS_Ph2 (TR 21.918 clause 17.12) states that the data collection, reporting and exposure feature applies to both downlink and uplink media streaming (TS 26.501 clauses 4.7, 5.11 and 6.8).
- TS 26.531 V18.0.0 clause 5.5 adds a sentence to step 13 (the UE application may instruct the Direct Data Collection Client to prioritise immediate delivery of a UE data report to the Data Collection AF) and to step 14 (the Direct Data Collection Client may indicate that the data report includes UE data requiring expedited processing by the Data Collection AF); V17.3.0 has steps 13 and 14 without these sentences. In TS 26.532, the
expediteproperty of a data report (clause 7.3.2.3) is first in V18.0.0 (CR 0005), the MS_ANBR_NETWORK_ASSISTANCE data domain (clause 7.3.3.1) is first in V18.1.0 (CR 0004), and the reporting context identifiers (clause 4.1) are first in V18.3.0 (CR 0013); none of the three is in V17.3.0. - Related SA2 and CT work: eNetAE (TR 21.918 clause 26.2) lists the impact of user consent on data collection and storage for the Nnwdaf, Ndccf and Nnef services.
The other Release 18 change requests are tagged EVEX and TEI18 ("(Small) Technical Enhancements and Improvements for Rel-18"), with these exceptions: TS 26.531 CR 0007 and TS 26.532 CR 0005 are also tagged ADAE, and TS 26.531 CR 0008 and TS 26.532 CRs 0014 and 0015 carry no tag.

The work plan also lists the CT3 part of EVEX, which changed TS 29.517, TS 29.522 and TS 29.591. The EVEX work item description, SP-210374 (clause 5), names two new specifications, "Data Collection and Reporting; General Description and Architecture" and "Data Collection and Reporting; Protocols and Formats", and lists TS 26.501 and TS 26.512 as impacted.
What the release descriptions add:
- TR 21.917 clause 15.6 summarises EVEX. It relates the work to the SA2 work item eNA_Ph2 (UE data collection and event exposure by an AF to event consumers such as the NWDAF) and to the CT3 work item EVEX. The summary describes the Data Collection AF, the Direct and Indirect Data Collection Clients, the Provisioning AF and the optional NEF, and the extension of the 5GMS M1 API in TS 26.512 with Data Access Profiles.
- TR 21.917 clause 9.4.3 (eNA_Ph2) lists "UE data as an input for analytics generation (via AF)" and "User consent for UE data collection/analysis" among its framework enhancements.
- TS 29.517 CR 0069 "Support UE Application event exposure via Data Collection AF" (CT#96, June 2022) is in V17.6.0 (change history of TS 29.517 V20.1.0).
Both specifications were placed under change control at SA#96 (June 2022) as version 17.0.0.
