8.2  Solution evaluationsp. 51

8.2.1  Generalp. 51

All the key issues and solutions specified in this technical report are listed in Table 8.2.1-1. This Table includes the mapping of the key issues to the solutions and corresponding solution evaluations.
Key issues Solution Dependency on other working groups
Key issue #1: Support for application performance analyticsSolution #1: Support for application performance analytics
Solution #2: Data Analytics Enablement
Solution #4: Support for performance analytics for UE-to-UE sessions
Solution #5: Service experience to support application performance analytics
Key issue #2: Support for edge analytics enablement Solution #2: Data Analytics Enablement
Solution #3: Support for edge load analytics
Key issue #3: Support for data collection for application layer analyticsSolution #2: Data Analytics Enablement
Key issue #4: Key Issue on interactions with SEAL servicesSolution #2: Data Analytics Enablement
Solution #6: Support for slice related application data analytics
Solution #7: Slice configuration recommendation
Solution #8: Location accuracy analytics
Key issue #5: Support for slice-related application data analyticsSolution #6: Support for slice related application data analytics
Key issue #6: Support for slice configuration recommendation enablement Solution #7: Slice configuration recommendation
Key issue #7: support for location accuracy analytics Solution #8: Location accuracy analytics
Key issue #8: Support for service API capability analyticsSolution #9 : Service API analytics
More specifically,
  • For Key issue #1 (Support for application performance analytics), Solution #1 and Solution #4 provide analytics capabilities for application performance targeting the UE-to-network and UE-to-UE sessions respectively. Solution #2 provides a generic mechanism which can be used for data analytics enablement and can be adopted by Solutions #1 and #4; whereas Solution #5 provides methods for collecting/notifying service experience data from the UE and can be seen as further elaboration of the collection/notification means based on Solution #1. There is no identified conflict among the solutions, and the solutions can complement each other.
  • For Key issue #2 (Support for edge analytics enablement), Solution #3 provides analytics functionality for edge load, whereas Solution #2 provides a generic mechanism which can be used for edge load analytics enablement and can be adopted by Solution #3 (whereas it is not mandatory). Solution #2 may require enhancements in eEDGEAPP to allow the collection of the EES load information.
  • For Key issue #3 (Support for data collection for application layer analytics), Solution #2 provides a generic mechanism for data collection enablement to be used for ADAE analytics derivation.
  • For Key issue #4 (Key Issue on interactions with SEAL services), solutions #2, #6, #7, #8 have interactions with other SEAL services. Solution #2 provides a generic mechanism for data collection enablement to be used for ADAE analytics derivation. Additionally, Solution #6 and #7 interact with SEAL NSCE server for analytics derivation. Finally Solution #8 collects location reports from SEAL LMS and may require location enhancements of SEAL LMS. There is no identified conflict among the solutions, and the solutions can complement each other.
  • For Key issue #5 (Support for slice-related application data analytics), Solution #6 provides slice-related application analytics and is optionally interacting with SEAL NSCE service (no enhancements are needed at SEAL NSCE).
  • For Key issue #6 (Support for slice configuration recommendation enablement), Solution #7 provides a support capability for slice configuration recommendation and is interacting with SEAL NSCE service (no enhancements are needed at SEAL NSCE).
  • For Key issue #7 (support for location accuracy), Solution #8 provides location accuracy analytics functionality and is optionally interacting with SEAL LMS or FLF service (enhancements are needed at SEAL LMS if used as data source).
  • For Key issue #8 (Support for service API capability analytics), Solution #9 provides a support capability for service API analytics.
