E2 Simulator Usage: - How to configure E2Sim to initiate the connection towards E2Term(nRT-RIC) - The E2 Simulator breaks up the simulation roles into two: 1. Base E2AP support (is the role supported by E2 Simulator library) 2. E2SM Support (is supported by the calling application) ![](https://i.imgur.com/Gs7j17R.png =350x) ## 1.1 Flow: 1. Upon startup, Simulator generates E2 Setup Request For each E2SM that is registered, include RAN function definition 2. Upon receiving incoming requests, decode Identify RAN function ID Call appropriate callback function for RAN function ID and request type Provide entire encoded request If no callback is provided, we return an error response 3. Upon receiving responses, decode: Identify RAN function ID If a callback is registered for this message type, call it based on RAN function ID and request type Provide entire encoded response If no callback is registered, no action is taken ## 1.2 E2SM E2 Simulator enables a specific E2SM to be supported by the calling application in the following way: * E2SM must be registered by the calling application * E2SM-specific code uses callbacks to handle interaction from xApp * E2SM-specific code must continuously implement simulation logic Registration of an E2SM with the E2 Simulator entails the following: * RAN function definition * Callback functions for any of the following: Subscription Control Any Responses ## 1.3 E2SM Callback Functions: * Callback functions are responsible for sending responses * They may also need to set up ongoing simulation messaging REPORT Service sends back periodic Indication messages containing REPORT INSERT Service sends back periodic Indication messages containing INSERT * They may need to associate incoming messages with existing service invocation Modify Subscription CONTROL message associated with INSERT * Base E2 simulator should not be concerned with these details; only specific E2SM code should be responsible for any messaging ## 1.4 Simulation For this simulation, we make the following assumptions: DU ID can differ and we assign a separate ID CU-CP and CU-UP are always the same Cell Identities are different FQI and QFI Values are the same # 2.
