Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: 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.

The processor is configured to: receive a signal broadcast from an access station; obtain network slice congestion information from the signal; apply the URSP to the network slice congestion information to select a network slice; and establish a session with the selected network slice.

Abstract: 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.

The one or more processors are configured to: obtain network traffic comprising first network traffic and second network traffic, wherein the second network traffic originates from one or more user equipment devices (UEs); apply the URSP to the network traffic; and in response to applying the URSP, forward protocol data units (PDUs) of the network traffic to either a first tunnel to a first network slice or a second tunnel to a second network slice. The first tunnel and the second tunnel are established from the device to the first network slice and the second network slice over communication paths that include at least a wireless communication link from the device to a radio access network (RAN).

Abstract: A device comprises a memory and one or more processors. The memory stores a User Equipment Route Selection Policy (URSP). The one or more processors are configured to: receive a packet from a user device; determine a traffic descriptor associated with the packet; apply a URSP to the traffic descriptor to identify a network slice, within a network, to which the packet is to be forwarded; and forward the packet to the network slice over a wireless connection from the device to the network.

Abstract: 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 (“UE”) 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 (“DRBs”), backhaul links, protocol data unit (“PDU”) sessions, or other suitable types of communication sessions.

Abstract: Systems and methods described herein bring a 5G standalone-capable end device back into 5G service to leverage the 5G network's data capacity as soon as a VoLTE call is over. A network device receives a fallback connection, for a 5G New Radio (NR) standalone-capable end device, from a second network to the first network to support a voice call on the end device, wherein the fallback connection supports a voice-over-LTE call. The network device detects an end of the VoLTE call and initiates, in response to the detecting, a handover of the end device back to the second network, wherein the initiating occurs while the end device is in a radio resource control (RRC) connected mode.

The network device may perform a registration procedure and a policy procedure pertaining to an end device. The network device determines when the registration and the policy procedures are completed. The network device transmits a registration response that includes an end device policy to an end device.

Abstract: 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.
