摘要： A system described herein may provide a technique for allocation and/or preemption of radio access network (“RAN”) resources in a wireless network based on Quality of Service (“QoS”)-related metrics associated with User Equipment (“UEs”) that are connected to, and/or are requesting connection to, a RAN. QoS-related metrics may include a network slice, a QoS Flow Identifier (“QFI”), other suitable metrics. A Slice-Based Priority (“SBP”) determine one or more priority (e.g., SBP) values for UEs connected to the one or more RANs, and/or for UEs requesting connection to such RANs. In addition to QoS-related metrics priority values may be determined based on RAN-related metrics, such as Allocation and Retention Priority (“ARP”) values associated with a UE. RANs may accordingly be able to allocate resources, accept or deny connection requests, and/or perform preemption based at least partly on slice-related QoS metrics, thus preserving end-to-end QoS parameters.

摘要： Systems and methods described herein use group segmentation of applications (referred to herein as “slicing classes”), based on common service requirements, to allow carriers to assign UE traffic to network slices. A UE stores slicing class definitions for use with UE Route Selection Policies (URSP). Each of the slicing class definitions include network quality of service (QoS) characteristics that are applicable to network traffic for multiple software applications. The UE maps the software applications to corresponding slicing class identifiers associated with the slicing class definitions. The UE also stores URSP rules for associating a slicing class identifier with a network slice identifier. A UE operating system sends, to a modem, one of the slicing class identifiers for an application that is requesting attachment to a wireless network. The modem sends a registration request with a selected network slice identifier based on the received slicing class identifier and the URSP rules.

摘要： A method may include identifying service requirements associated with a network service, identifying at least one analytics component to monitor the network service and identifying network functions to implement the network service. The method may also include deploying the network functions to monitor the network service, deploying the at least one analytics component and obtaining data associated with monitoring the network service. The method may further include forwarding, by the network functions, the data to the at least one analytics component and determining, by the least one analytics component, whether to take a control action with respect to the network service.

摘要： A device may include a processor configured to receive wireless communication network policies from an orchestration system. The device may be further configured to receive a notification from a radio access network (RAN) central unit (CU) that a packet data unit (PDU) session has been set up in the RAN, wherein the notification includes information associated with the PDU session; identify a programmable switch associated with the PDU session; select a policy, from the plurality of wireless communication network policies, based on the information associated with the PDU session; and configure the programmable switch to apply the selected policy to the PDU session.

摘要： Systems and methods enable data collection and analytics consumption with a generalized assurance framework using a message bus that supports a publish-subscribe model. A producer network element subscribes to a request topic on the message bus and posts, to the message bus, an announcement indicating a data topic is available from the producer network element. The producer network element receives via the message bus, the request topic including a request for the data topic and posts, to the message bus, records for the data topic in response to the request.

摘要： A method, a device, and a non-transitory storage medium are described in which a network slice-to-transport domain service is provided. The service includes correlating a network slice identifier, an Internet Protocol subnet, and a virtual routing and forwarding instance pertaining to a network slice, and configuring network devices of the network slice with at least a portion of the correlated information. The service may obtain feedback information from the network devices, and evaluate performance metrics pertaining to the network slice based on the correlated information.

摘要： A method, system, and computer-readable medium may provide for receiving network performance indicator data associated with a network slice connected to a user equipment (UE) device via a first type of network infrastructure; determining, based on the network performance indicator data, that one or more service level agreements (SLAs) for the network slice will not be met or are not currently being met; identifying a second type of network infrastructure based on service requirements for the network slice, wherein the network requirements include the one or more SLAs and a service profile; accessing a network function virtualization infrastructure (NFVI) inventory to determine a supportability for the instantiation of the second type of network infrastructure; and instructing an orchestrator to deploy the second type of network infrastructure over the access network.

摘要： A device associated with a network may receive a service profile for a network slice of the network, where the service profile includes one or more service characterizations of the network slice. The device may determine, based on thresholding rules and for each service characterization, whether the service characterization requires selection from a plurality of building blocks, to obtain a group of service characterizations requiring selection. The device may select, based on selection rules and for each service characterization of the group of service characterizations requiring selection, a building block from the plurality of building blocks, to obtain selected building blocks, where the selection rules map attributes of service characterizations to building blocks. The device may stack, based on stacking rules, the selected building blocks, to obtain a slice infrastructure for the network slice. The device may deploy the slice infrastructure for the network slice in the network.
