Near-Real-time RAN Intelligent Controller Platform (E2 Interface) (RICPLT)

Primary Goals: More manageability of the RIC platform, including platform alarms, platform stats from E2 and A1 and support for direct RMR-to-VES event conversion for VES stats, Support operator-initiated health-check via E2 and E2 connection state, E2 can reject new connection setup requests. REST interface for E2 subscriptions, further xApp framework APIs.

Cherry feature scope: Detailed list of JIRA items that we plan to work on in Cherry (requires LinuxFoundation login): link(28 items)

Status 2020-09-02: (a) I (PTL) am happy to see teams from Samsung and HCL joining the project with them actively working on capabilities related to the E2 simulator (actually in Alex' simulator project), more test automation (using the robot framework), benchmarking, SDL (shared data layer). (b) RIC-372 was the first commit from these new participants (c) we might be aiming for self-certification under LF's CII badge level "basic", (d) work on O1-related functions, like E1 and A1 statistics, or some alarms already done. (e) Adaptation to E2APv1.1 only happening post-Cherry.
