Abstract:

A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.

International Classification:

H04L 9/32
G06Q 20/06

Abstract:

A Network Function (NF) entity in a telecommunication network receives blockchain credentials associated with UE and selects a Blockchain Charging Function (BCF). The NF entity further generates a Charging Data Record (CDR) corresponding to network resources, and sends a charging request based on the CDR (and policy rules) to the BCF entity over a blockchain network interface. The BCF entity sends a confirmation of the charging request, and the NF entity, based on the confirmation, provisions the network resources to the UE.

H04W 12/06
H04W 12/08
H04W 8/24

Abstract:

Various implementations disclosed herein enable blockchain programming in NB-IoT devices. In various implementations, a method of blockchain authentication is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations, the method includes maintaining a blockchain for a machine-to-machine network, wherein the machine-to-machine network is a narrowband internet of things network. In some implementations, the method includes receiving a request for a first set of data from the blockchain by a second device. In some implementations, the method includes determining based on the request, the first set of data from the blockchain by traversing a series of blocks from the blockchain. In some implementations, the method includes packaging the first set of data from the blockchain according to a protocol into a packaged data unit and transmitting the packaged data unit to the second device.

Abstract:

A network function (NF) entity in a communication network receives authentication data associated with a User Equipment (UE), determines the UE supports a blockchain registration procedure based on the authentication data, exchanges authentication messages with a Blockchain Roaming Broker (BRB) entity over a blockchain network interface, receives a blockchain authentication confirmation from the BRB entity, and registers the UE with the core network based on the blockchain authentication confirmation.

H04L 12/721
G06F 13/00
G06F 13/12

Abstract:

In accordance with various implementations, a method is performed at a data plane node with one or more processors, non-transitory memory, and a control interface between a network function module associated with the data plane node and a switch associated with the data plane node. The method includes determining whether an offload capability is available for a data flow received at an ingress network interface of the data plane node. The method also includes determining whether the data flow satisfies offload criteria in response to determining that the offload capability is available. The method includes bypassing the network function module associated with the data plane node and providing the data flow to at least one of the switch associated with the data plane node or an egress network interface associated with the data plane node in response to determining the offload capability is available and the offload criteria is satisfied.

H04W 12/06
G06F 17/30

Abstract:

Methods and apparatus for use in reducing signal latency in a mobile network with use of localized Unified Data Management (UDM) entities are described. For example, the technique may employ a plurality of localized UDMs, where each localized UDM is associated with a unique location area. A localized UDM provides for storage of, in a localized Unified Data Repository (UDR), subscriber profile data associated with a subscriber of user equipment (UE). The subscriber profile data stored in the localized UDR may be a replica or copy of at least a subset of subscriber profile data for the subscriber stored in a UDR of a “centralized” UDM. Query access to the localized UDR may be provided for network functions (NFs) or subscriber/UEs. The replica or copy of subscriber profile data may be stored in the localized UDR for those subscribers having use in the location area.

International Classification:

G06F 9/50
H04L 12/875
H04L 12/863

Abstract:

Disclosed is a method that includes periodically observing packets in a user plane according to at least one key performance indicator in a configuration file to yield an observation, wherein the observation represents a closed-loop demand of resources within the user plane. The method includes adjusting, via a scheduler in the user plane and based on the observation, a binding of cores to work items. The binding between cores and work items is dynamic and changeable to improve performance. The at least one key performance indicator can include one or more of a CPU utilization, latency and packet drops. The workload allocations can include work items that are individually scheduleable functions that operate on a queue of packets within the user plane.
