Abstract: There is a need for a non-RT RIC to cause E2 sessions to be reset at a node. Accordingly, a system is described comprising a non-Real Time (RT) Radio Area Network (RAN) Intelligent controller (RIC), wherein the non-RT RIC further comprises an operations administration maintenance (OAM) server; a near-Real Time (RT) Radio Area Network (RAN) Intelligent controller (RIC) in communication with the non-RT RIC; and an E2 node in communication with the near-RT RIC providing connectivity to one or more User Equipments (UEs). The OAM server may be configured to periodically perform assessment of the E2 node. The near-RT RIC may be configured with an application programming interface (API) to enable the non-RT RIC, based on an assessment by the OAM server, to perform an E2 reset of E2 sessions at the E2 node.

Abstract: A method for optimizing parameters affecting Paging Optimization is disclosed, comprising: determining a first paging stage timeout value based on at least one of how much congested is the radio network, and whether paging from a same sub from a same location but paging optimization had already moved to a second stage; determining a second paging stage timeout value based on receiving retransmissions from core network for the same sub within this time; and how many times the subscribers respond later after the timer expiry; and applying a function to the paging cache timeout value, the first paging stage timeout value; and the second first paging stage timeout value to obtain a paging optimization value.

Abstract: A method providing Open Radio Access Network (RAN)—Multi-Access Edge Computing (MEC) information exchange is disclosed, the method comprising: providing an xApp for RAN-MEC information exchange; providing an rApp for RAN-MEC information exchange; acting, by an RM Application Programming Interface (API) service, as an aggregation point in MEC platform; exposing aggregated information from the RM API to a MEC application; and leveraging information shared by RAN functions over an O1 interface or over an E2 interface.

Abstract: In a first embodiment, a system may be disclosed, comprising: a plurality of RAN nodes, each with X2 and E2 interface capability; an X2 interface gateway in X2 communication with each of the plurality of RAN nodes; and a near Real-Time RAN Intelligent Controller (near-RT RIC) in communication with the gateway via an E2 interface, The X2 interface gateway provides E2 interface gatewaying for the plurality of RAN nodes with the near-RT RIC, thereby enabling the near-RT RIC to avoid an individual E2 protocol connection with each of the plurality of RAN nodes.
