Abstract: Methods, computer-readable medium and a system are described for handling data traffic during Dedicated Bearer creation at a Packet Gate Way (PGW). In one embodiment, a method includes receiving, at a PGW user plane from a PGW control plane, a PFCP session modify request; creating a PDR-id (P1); sending, from the user plane to the control plane, a PFCP session modify response; receiving, at the control plane, downlink data matching PDR(P1); and performing at least one of allowing data since FAR(Fx) has a forwarding parameter, and sending data to peer node as per FAR (F1) forwarding parameters.

Abstract: In one embodiment, a method is disclosed, comprising: receiving a packet; processing the packet in a Control Unit-User Plane (CU-UP) as a user-space application with kernel-bypass networking; performing packet Input/Output (I/O) by the CU-UP user-space application, wherein the CU-UP performs Internet Protocol (IP) validation on received user-plane packets before processing Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP) and General Packet Radio Service Tunnelling Protocol (GTPU) protocol stack and performing direct I/O to a Network Interface Controller (NIC) for sending the packet over a network to a Distributed Unit (DU). The method may further comprise using a containerized CU-UP. The method may further comprise using a plurality of worker threads. The method may further comprise using a polling user space networking accelerator framework.

Abstract: A method is disclosed, comprising: in a general packet radio services (GPRS) tunneling protocol (GTP) message to update a GTP tunnel with a traffic flow template (TFT), sending a first opcode in a header of a TFT message; sending a second opcode in a packet filter field of the TFT message; interpreting the first opcode to initiate at least two of creation, deletion, and updating of traffic flow templates (TFTs); and interpreting the second opcode to identify an existing packet filter for adding, replacing, and deleting a packet filter.

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 for linking Packet Detection Rules (PDRs) for optimizing throughput of combined Serving Gateway (SGW)/Packet Gateway (PGW) architecture is disclosed. In one embodiment the method includes, determining a SGW and a PGW are co-located on a system and when the SGW and PGW are co-located on a same system then performing a Packet Forwarding Control Protocol (PFCP) session lookup for an uplink packet at the SGW; determining which PDR to use for sending the uplink traffic; using the PDR to remove any tunneling protocol header; checking the PDR to determine if the next hop is local; when the next hop is local, then finding the PGW PDRs for this FTEID; identifying a PGW PDR matching with the current packet; performing any packet encapsulation; and after performing any optional header checksum calculations, sending the packet.

Abstract: Methods and computer readable medium are disclosed for providing an outer header for a packet. In one embodiment a method includes receiving an outer header creation IE type encoded and containing instructions to create an outer header, an outer header creation description field taking a form of a bitmask, each bit indicating the outer header to be created in the outgoing packet; wherein when the outer header creation packet creation IE requests creation of an IP header, a source IP address is included in an IP header of an outgoing packet; and sending the outgoing packet including a source IP in the newly added outer IP header.
