A system described herein may apply an authorized set of traffic parameters, such as network slicing parameters, Quality of Service ('QoS') parameters, etc. to traffic associated with a particular application, without exposing an identifier of the traffic to one or more network devices of a network that handles the traffic. A client associated with a User Equipment (“UE”) may selectively apply traffic parameters to traffic associated with the particular application further based on whether a UE-side authorization of the particular application for the traffic parameters has been performed. The UE may present a user interface via which a user may select whether to authorize or deny the use of traffic parameters, authorized by the network, for the particular application. If the particular application has been authorized by both the network and the user of the UE, the UE may apply the traffic parameters to traffic associated with the particular application.

Systems and methods for selectable application-specific quality of service parameters in a wireless network

A device may include a processor configured to send a plurality of attach requests to a base station using a radio access technology (RAT) and determine that each of the plurality of attach requests has failed. The processor may be further configured to override a triggering of a backoff timer, wherein the UE device is barred from attaching using the RAT if the backoff timer is triggered and running, in response to determining that each of the plurality of attach requests has failed, and send another attach request to the base station using the RAT during a time period associated with the backoff timer.

Systems and methods for handling non-access stratum layer failures

A system described herein may provide a technique for a policy and/or rules element of a core network, such as a Policy Control Function ('PCF'), to identify a first network slice with which a communication session between a User Equipment (“UE”) and a core network, such as a protocol data unit (“PDU”) session, is associated. The policy and/or rules element may identify a second network slice with which the communication session should be associated, such as based on traffic monitoring, network congestion monitoring, or other criteria, and may output an indication, indicating a second network slice, to a session control element, such as an Session Management Function (“SMF”). The session control element may cause the communication session to be moved from the first network slice to the second network slice based on receiving the indication.

Systems and methods for network slice modification by policy control function in a wireless network

A device described herein may maintain information associating sets of traffic attributes with respective sets of Quality of Service ('QoS') parameters, and may receive a request to establish a traffic flow. The request may indicate one or more traffic attributes associated with the requested traffic flow. The device may compare the one or more traffic attributes, included in the request, to the information associating the sets of traffic attributes with the respective sets of QoS parameters, identify a particular set of QoS parameters with which the traffic flow is associated, establish a communication session with a network based on the particular set of QoS parameters, communicate traffic, associated with the traffic flow, with the network via the established communication session. The device may include an application programming interface (“API”) via which an application associated with the traffic flow may specify the traffic attributes in the request.

Systems and methods for quality of service treatment of network traffic based on traffic attributes

A device described herein may receive an indication that the device is not authorized to access a first type of core network (e.g., a Fifth Generation ('5G') Core (“5GC”)), and may detect that a first core network, of the first type of core network, is available for communication. The device may detect that a second core network, of a second type of core network (e.g., an Evolved Packet Core (“EPC”)), is available for communication. Based on the indication that the device is not authorized to access the first type of core network, the device may request establishment of a communication session with the second core network (e.g., in lieu of requesting access the first core network).

Systems and methods for 5G core network access control

A method, a device, and a non-transitory storage medium are described in which a network slice selection service is provided. The service may include using route selection policies that includes radio frequency criteria for selection of a network slice. The service may include establishing an application session based on the route selection policies. The service may further include determining that a radio frequency of the network slice cannot be sustained. The service may include executing an application session release procedure and an application session establishment procedure. The procedures may include using cause data and context data pertaining to the initial application session to re-establish the application session via a different network slice and a different radio frequency based on the route selection policies.

Method and system for end device network slice selection

A method, a device, and a non-transitory storage medium are described in which an inter-RAT PDN connection management service is provided. The service may include provisioning a packet data network (PDN) session based on network slice (NS) and access point name (APN) information received from an end device via a non-slice radio access device. The service may further include provisioning, during the PDU session, a network slice based on the NS and APN information in which core devices of the network slice are selected and the same as the core devices that supported the PSN session.

Method and system for inter-radio access technology packet data network connection management

A network device may receive, from a user equipment, a dataset identifying: applications utilized by the user equipment, network protocol types associated with the applications, and network addresses associated with the applications. The network device may segregate the dataset based on the network protocol types and to generate a segregated dataset. The network device may determine, based on the segregated dataset, a policy that causes particular application traffic associated with a particular network protocol type to be allocated to a particular network slice of the network. The network device may cause the policy to be provided to the user equipment to cause the user equipment to allocate the particular application traffic associated with the particular network protocol type to the particular network slice of the network.

Systems and methods for determining a policy that allocates traffic associated with a network protocol type to a network slice

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.

Systems and methods of application mapping for network slicing using group segmentation

A system may obtain information that indicates when a plurality of network slices are overloaded; generate a message that indicates which of the network slices are barred from access by wireless mobile terminals based on the information; and broadcast the message over a downlink wireless signal to a cell serviced by the system.

Systems and methods for access barring based on slice information

A user equipment may generate one or more temperature thresholds based on thermal mitigation guidelines. The one or more temperature thresholds may define a first temperature zone and a second temperature zone. The user equipment may detect a temperature of the user equipment. The user equipment may identify whether the temperature occurs in the first temperature zone or the second temperature zone. The user equipment may send information to a network device to cause one or more network actions to be performed. The one or more network actions may be configured to maintain or reduce the temperature within the first temperature zone or to reduce the temperature to cause the temperature to switch from the second temperature zone to the first temperature zone.

System and method for user equipment-side thermal mitigation

Systems and methods described herein enforce access controls for network slices via proxy in a secure enclave of a user equipment (UE) device. A UE device executes, in a rich execution environment (REE), a function or application designated for using one or more secure network slices of a telecommunications network. The UE device executes, in a trusted execution environment (TEE), a slice admission control proxy (SACP) to perform admission control for the one or more secure network slices, and forces network traffic for the function or application through the SACP.

Provider proxy for controlling network slice access by user equipment

A system described herein may provide a technique for the differentiated Quality of Service ('QoS') treatment of different traffic types associated with the same application (e.g., a 'multi-persona' application) by a wireless network, without the exposure of an application identifier of the application to the wireless network. The application may provide a traffic type indication, based on which a User Equipment (&#x201c;UE&#x201d;) may establish one or more QoS flows or other types of communication sessions with the wireless network, where the QoS flows or other types of communication sessions are associated with a network slice that is associated with the traffic type. The communication sessions may include Data Radio Bearers (&#x201c;DRBs&#x201d;), backhaul links, protocol data unit (&#x201c;PDU&#x201d;) sessions, or other suitable types of communication sessions.

Systems and methods for differentiated traffic treatment for different traffic types associated with multi-persona applications

A user device may receive information indicating that a universal integrated circuit card has been installed in the user device, where the universal integrated circuit card may store a default table that includes network slice selection assistance information used to route data from the user device to correct slices of a network. The user device may execute an application stored in the user device based on receiving a selection of the application, where execution of the application may cause data to be generated. The user device may identify a slice of the network to which to route the data based on the network slice selection assistance information included in the default table. The user device may cause the data to be routed to the slice of the network identified based on the network slice selection assistance information included in the default table.
