- no RIC-784 (timer handling in E2 control messages),
- no RIC-785 (error indication handling),
- no RIC-783 (support for control ack to selected xapps)
- no E2 Reset from RIC to RAN (RIC-386+-387) - the other direction from RAN to RIC (RIC-387386) is supported.
- In submgr we only support Subscriptions with single actions (RIC-75).
- No support for multiple TNL associations, i.e., no E2 Connection Update procedure (RIC-639)
- RIC subscription delete required is terminated by the submgr (the interface towards xApps for this is coming only via RIC-967).
- No support for the E2 removal procedure (simple SCTP disconnect is currently the way)
Note that the RIC platform is generally independent of E2SMs (E2 service models) and E2APv1.0, 1.1, 2.0 work with the various E2SMs as there are no dependencies.
