Abstract: The present invention provides UE mobility context creation at RIC/ORAN in 4G and 5G systems. It does this by determining a User Equipment (UE) UE is moving seamlessly from across CUs in connected mode using S1/X2/N2/Xn Handovers; downloading, by a non RT RIC, a policy to connected CUs that whenever a UE latches with initial UE message, CU sends an Identity Request to get the UEs SUPI; determining whenever the UE attaches to the CU/DU with the initial UE message, the SUPI is learnt and sent back to the Non RT RIC, along with the SUPI CU/DU and sends CRNTI, STMSI, cell information as per the use cases; allocating, by the Non RT RIC, a fresh UE ID and creating a context with parameters including Current Location, UE ID allotted by RIC, Current CRNTI, and cell information; sending, by the Non RT RIC, the fresh UE ID to the CU that the CU maintains as part of the UE context information.
