maximessone6b4d272019-10-31 13:26:13 +010012There are functional requirements emitted by O-RAN WG2 for the Non-RT RIC, which are the following:
13
elinuxhenrikc7a0d732020-02-04 14:49:59 +010014#. Non-RT RIC shall support data retrieval and analysis; the data may include performance, configuration or other data related to the application (recommended data shown in required data section for different use cases).
15#. Non-RT RIC shall support relevant AI/ML model training based on the data in 1. for non-real-time optimization of configuration parameters in RAN or Near-RT RIC, as applicable for the use case.
16#. Non-RT RIC shall support relevant AI/ML model training based on the data in 1. for generating/optimizing policies and intents to guide the behavior of applications in Near-RT RIC or RAN, as applicable for the use case.
17#. Non-RT RIC shall support training of relevant AI/ML models based on the data in 1. to be deployed/updated in Near-RT RIC as required by the applications.
18#. Non-RT RIC shall support performance monitoring and evaluation.
19#. Non-RT RIC shall support a fallback mechanism to prevent drastic degradation/fluctuation of performance, e.g. to restore to the previous policy or configuration.

21The non-functional requirements are the following ones:
22
maximessonf217fff2020-04-09 15:16:04 +020023#. Non-RT RIC shall not update the same policy or configuration parameter for a given Near-RT RIC or RAN function more often than once per second.
24#. Non-RT RIC shall be able to update policies in several Near-RT RICs.

26Moreover, there are functional requirements regarding the A1 interface:
27
elinuxhenrikc7a0d732020-02-04 14:49:59 +010028#. A1 interface shall support communication of policies/intents from Non-RT RIC to Near-RT RIC.
29#. A1 interface shall support AI/ML model deployment and update from Non-RT RIC to Near-RT RIC.
30#. A1 interface shall support communication of enrichment information from Non-RT RIC to Near-RT RIC.
31#. A1 interface shall support feedback from Near-RT RIC for monitoring AI/ML model performance.
32#. A1 interface shall support the policy/intents feedback from Near-RT RIC to Non-RT RIC.
