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.

OpenRAN intelligent dynamic CU-UP scaling solution

Presented herein are embodiments that provide mobile edge computing (MEC) with low latency traffic segregation within a packet data network (PDN) using dedicated bearers. Techniques are provided that are performed at an edge user plane entity and a control plane entity to coordinate the directing of low latency traffic over a dedicated bearer broken out at the edge, and to communicate normal latency traffic over a default bearer that is centrally broken out.

Systems, methods and computer software are disclosed for providing for providing a 5G mobile network. In one embodiment a method is disclosed, comprising: providing a first base station having a first coverage area for a first Radio Access Network (RAN); providing a second base station having a second coverage area, the second coverage area within the first coverage area of the first base station for an overlay RAN; providing a 5G base station having a third coverage area, the third coverage area within the first coverage area and within the second coverage area and part of the overlay RAN; and determining, by a 5G Interworking Function (IWF) device, which subscribers are to be serviced by the overlay RAN and which subscribers are to be serviced by the first RAN.

Techniques that provide low latency traffic segregation to ensure an edge user plane (UP) is not overloaded are described herein in at least one embodiment. In at least one embodiment, a method may include determining offload of low latency traffic of a user equipment (UE) at a mobile network edge, wherein the UE has non-low latency traffic associated with a first packet data network session for an access point name; notifying the UE to request creation of a second packet data network session for the access point name; selecting an edge UP element to handle the low latency traffic for the second packet data network session; creating the second packet data network session at the selected edge UP element; and notifying the UE that second packet data network session is created.

Providing low latency traffic segregation for mobile edge computing network environments

Systems and methods for MME adaptive selection are described. The method includes: initializing a health checkup algorithm at an eNodeB for each MME connected to as per configuration values; starting a health check timer for each MME; continuing with an Initial Attach procedure for incoming calls based on SAE-Temporary Mobile Subscriber Id (S-TMSI), (Globally Unique MME Identifier) GUMMEI, or capacity/load balancing considerations; on every UE attach attempt, incrementing a total calls count; and on every S1 AP Error Indication/no response from an ME, incrementing a total fail calls count; determining when the health check timer for an MME expires; calculating a failed calls/total calls percentage value. Based on the value of the timer, appropriate action is taken.

Adaptive MME selection method for an incoming UE

Various embodiments disclosed herein provide a method for grouping user planes in 4G/5G packet cores to simplify user plane discovery and registration. In some embodiments the method includes detecting a plurality of User Planes (UPs), grouping a first subset of the UPs into a first UP group, in which each UP in the first UP group is associated with a first set of features, and allocating the first UP group to a first network service based on the first set of features associated with the first UP group and a first set of requirements of the first network service. The method further includes grouping a second subset of the plurality of UPs into a second UP group, in which each of the second UP group is associated with a second set of features and allocating the second UP group to a second network service of a plurality of network services.

User plane group

In one embodiment, a method is performed. A first user plane entity may be associated with a user plane group comprising a plurality of user plane entities. The first user plane entity may be associated with a second user plane entity. A failure of the second user plane entity may be detected. In response to detecting the failure of the second user plane entity, the first user plane entity may be activated.

Redundancy support for control and user plane separation

In one embodiment, a method for selecting a software interface based on operator policy comprises receiving from a mobile device a message requesting that a packet data session be allocated, wherein the message includes a requested quality of service profile for the packet data session, selecting a software interface, from among a plurality of software interfaces, for communication with a packet node based on the contents of the message, for the packet node to provide the mobile device with access to a packet data network, and allocating the packet data session in communication with the packet node, wherein the requested quality of service profile is conveyed to the packet node using the selected software interface.

Interface selection for quality of service enforcement

A method is provided in one example embodiment and includes analyzing characteristics of traffic associated with an application in a data communications network; defining each of a plurality of Access Point Names ('APNs') for terminating traffic in the data communications network; comparing the application traffic characteristics with the APNs; and selecting one of the APNs based on results of the comparing, in which the selected one of the APNs is assigned to terminate the application traffic. In some embodiments, the application traffic characteristics include at least one of average data packet size, average uplink traffic volume, average downlink traffic volume, triggering traffic data generation, and session frequency. The method may further include periodically re-comparing the application traffic characteristics with the APNs and selecting a different one of the APNs based on results of the recomparing to terminate the application traffic.

Selective access point name assignment based on machine-to-machine traffic analysis

The present disclosure is directed at systems, methods and media for relieving RAN congestion in a core network. In some embodiments, RAN congestion information is reported from user equipment to a packet data gateway (PGW) through an eNodeB and a software gateway. The PGW can aggregate the RAN congestion information and periodically notify other network nodes, for example, a PCRF, about the aggregate congestion in a network. By aggregating RAN congestion information, the PGW can substantially reduce the signaling required to report RAN congestion in the core network.
