A system comprises one or more devices. The devices are configured to: receive a context associated with a flow of packets between a User Equipment device (UE) and a network slice in a wireless network; obtain one or more policy rules; apply the policy rules to the context and a model of a transport device to generate or update a map that assigns one or more contexts to queues within the transport device; and send the map to the transport device. The transport device is configured to: adjust parameters of the queues based on the map; shape traffic from each of the queues; schedule packets from the queues; and forward the scheduled packets.

Systems and methods for supporting network slice services using transport devices

A device may receive network data identifying a topology of network devices of a network, quality of service (QoS) rules for user equipment (UEs) and application flows associated with the network, QoS profiles for a radio access network (RAN) of the network, and service data flow (SDF) templates. The device may process the network data, with a model, to calculate a network device service level agreement (SLA) score, for each of the network devices on a sliding window, to generate network device SLA scores, and may aggregate the network device SLA scores to generate an end-to-end SLA score on the sliding window. The device may generate QoS configuration data based on the end-to-end SLA score, and may implement the QoS configuration data.

Systems and methods for control of applications based on quality of service monitoring

RAN events associated with IoT devices may be monitored and tracked. Profiles may be defined for different IoT devices. The profiles may specify resource limits for the IoT devices, including resource limits based on the RAN events. The IoT profiles may also define policy responses based on the occurrence of the RAN events. The policy responses may include charging rules, network access control rules, or other rules based on the resource usage of the IoT devices.

IoT profiles and network usage tracking and charging based on RAN events

A first device may receive data from one or more sensors associated with the first device. The data may indicate movements of the first device. The first device may be associated with a user. The first device may determine a state of the user indicated by the movements of the first device. The first device may determine whether the data is associated with the movements of the user inside one or more structures. The first device may generate a map for a structure, of the one or more structures, by combining the data received from the one or more sensors. The first device may provide the map for the structure for display and the data toward one or more second devices.

Generating an indoor map for a structure using data gathered by a user device

An exemplary security key bootstrapping system determines an application layer session security keyset uniquely associated with a client device and based on a subscriber identity master security credential. The subscriber identity master security credential is permanently stored within a component of the client device and is also stored on a subscriber identity management server associated with a provider network by which the client device is communicatively coupled with an application server system. The security key bootstrapping system uses the application layer session security keyset as a credential to provide end-to-end security for an application layer session between the client device and the application server system over the provider network. Neither the component of the client device nor the subscriber identity management server obtains the subscriber identity master security credential from an exchange of the subscriber identity master security credential over the provider network.

Methods and systems for bootstrapping an end-to-end application layer session security keyset based on a subscriber identity master security credential

Application actions are optimized by receiving actions from one or more distributed applications, translating the received actions into one or more network operation primitives, processing the network operation primitives to determine an optimized set of network operation primitives, determining an optimal execution sequence for the optimized set of network operation primitives, and executing the optimized set of network operation primitives based on the optimal execution sequence.
