Abstract: The presently described invention provides gNB-CU-UP data plane high availability in a public or private cloud. In one embodiment, a method of providing gNB-CU-UP data plane high availability in public/private cloud includes identifying, by an internal controller, when a data-plane Pod crashes; initiating, by the internal controller, procedures to make a passive POD to an active state; the procedures including at least one of: maintaining, by the passive POD, all flows of all active PODs in it as backup; identifying, by the passive POD, flows of the impacted data-plane POD and marking those flows to an active state; marking remaining non-active flows at the passive POD to be removed; triggering, by the internal controller, label changing of the passive data-plane POD; migrating data-plane Internet Protocol (IP) of crashed POD to the passive data-plane POD; and launching, by a Service Management and Orchestration (SMO), a new passive POD for backup.

Abstract: A system is disclosed for providing Open RAN CU-UP high availability, the system comprising: at least one active CU-CP; at least one active CU-UP in communication with the at least one active CU-CP; and at least one standby CU-UP in communication with the at least one active CU-CP; wherein when a message may be received from a CU-CP that detects a failure of the at least one active CU-UP, the at least one standby CU-UP may be configured to take over and become an active CU-UP, thereby providing failover redundancy for the at least one active CU-UP.

Abstract: A method is disclosed for providing singleton micro-service high availability, comprising: identifying, by an internal controller, that a pod/container has crashed; initiating, by the internal controller, a label change for an existing similar pod labeled as standby to active; matching a singleton micro-service selector label criterion; advertising the newly re-labeled existing similar pod as part of a singleton micro-service; and receiving, by the newly relabeled pod in the system, traffic directed on an IP address of the singleton micro-service.

Abstract: This disclosure provides dynamic spawning of CU-UP instances and migration of some of active subscribers from overloaded CU-UP instance to newly created CU-UP instance without service disruption. In one embodiment, a method of migrating an active subscriber from a first Centralized Unit-User Plane (CU-UP) instance to a newly provided second CU-UP instance includes determining a first CU-UP requires service; spawning the second CU-UP instance; and migrating a subscriber from the first CU-UP instance to the second CU-UP instance.

Abstract: A method is disclosed for providing a telecom microservice rolling upgrade, the method comprising: providing, by a Service Management and Orchestration (SMO), a new instance of F1 demux in a same cluster and namespace; advertising the new instance of the F1 demux to all PODs and micro services; informing, by the SMO, an old F1 demux to start a version upgrade to a new instance; sending, by the old F1 demux, a trigger to start a reconcile procedure to a new F1 demux; advertising that the old instance of the F1 demux is not available to take up new calls from internal PODs and micro-service, and is accepting traffic via the new F1 demux only; routing, by the old F1 demux, all incoming F1 traffic from a Distributed Unit (DU) to the new F1 demux; and instructing the DU, by the old F1 demux, to add a Transport Network Layer (TNL) association of the new F1 demux.

Abstract: A method is disclosed for client-server reconciliation for wireless telecommunication networks, comprising: determining, by a client system in a Radio Access Network (RAN) connected to a server in the RAN, a need for reconciliation with the server; terminating an HTTP connection; flushing a buffer; creating a current snapshot of the client system; sending the current snapshot to the server with an identifier for a particular server process; buffering a message at the client during reconciliation; sending a reconciliation complete message to the server to indicate that process has been completed and all the data from the client has been delivered to the server; and sending, by the client after the reconciliation is complete, the message that was buffered during the reconciliation to the server.

Abstract: Methods and systems are presented for providing a 4G-5G Open RAN User Plane Path. In one embodiment a method includes keeping, by a Distributed Unit (DU)/Centralized Unit (CU)-User Plane (UP), a list of local switch enabled subscribers; receiving an uplink data packet for a local switch enabled subscriber from a source device; comparing , by the DU/CU-UP, if a destination Internet Protocol (IP) address matches with any of IP addresses in the local switch enabled subscriber destination device IP addresses; and when the destination IP address matches, then switching by the DU/CU-UP the traffic and sending the data packet as a downlink traffic towards the destination device.

Abstract: Systems and methods are provided for telecom cloud scale down. In one embodiment, a method is provided comprising: deploying a coordinating node, which may be a CU-CP or CU-UP, in a microservices cloud infrastructure; receiving, at an internal controller at the coordinating node, a trigger request for scale down preparation; sending, from the internal controller, a scale down request to a first stateful telecom microservice; sending, from the first stateful telecom microservice, at least one existing session state distribution request to at least one additional stateful telecom microservice; distributing existing connection and session information to the at least one additional stateful telecom microservice; and sending, from the first stateful telecom microservice to the internal controller, a scale down preparation completion message, thereby performing telecom cloud scale down while mitigating disruptions to subscriber service. The method may further comprise terminating the first stateful telecom microservice.
