A device may include a processor configured to determine that Quality of Service (QoS) monitoring is to be performed for a communication session; generate a QoS monitoring policy for the communication session; and provide the QoS monitoring policy to a Session Management Function (SMF) associated with the communication session. The processor may be further configured to receive a QoS monitoring report for the communication session from the SMF and perform an action based on the received QoS monitoring report.

Systems and methods for quality of service monitoring activated by policy control function

A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an detection and autocorrection of stale session information service. The detection and autocorrection service may include the addition of a header, which may indicate date and time information, with a message that has an origination timestamp header. The header may be added to the message by an intermediary network device relative to origin and destination network devices associated with a network procedure. The header may enable detection by a network device of stale session information. The header may enable the network device to determine whether to ignore the message as a duplicate message or use the message to carry out the network procedure. In this way, duplicate messages that may include the same origination timestamp header may be managed and stale information may be detected.

Method and system for detection and autocorrection of stale session information

A network device may receive a context creation request based on a protocol data unit (PDU) session establishment request for establishing a PDU session with a user device, and may generate a policy context request based on receiving the context creation request. The network device may provide the policy context request to a policy control function (PCF), and may receive, from the PCF and based on the policy context request, policy rules for the PDU session. The network device may receive, from the PCF, a terminate PDU session notification indicating that a binding support function (BSF) is unreachable, and may generate, based on the terminate PDU session notification, a PDU session release command that includes a cause code indicating an issue with the BSF and an instruction to not reinitiate the PDU session. The network device may cause the PDU session release command to be provided to the user device.

Systems and methods for preventing user device pinging in asynchronous communication mode

In some implementations, a network device may obtain a message that includes service parameter data associated with an application. The service parameter data may indicate a revalidation time. The network device may generate, based on the service parameter data, a user equipment route selection policy (URSP) rule associated with the application that includes the revalidation time indicated by the service parameter data. The URSP rule may expire at the revalidation time. The network device may transmit the URSP rule for a user equipment (UE) that executes the application. The network device may receive a state indication message associated with the UE that is triggered at the revalidation time.

Systems and methods for user equipment route selection policy revalidation

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 method, a network device, and a non-transitory computer-readable storage medium are described in relation to an event reporting service. The event reporting service may enable network devices, such as an application function, to subscribe to usage reporting in which notifications for a usage event may be reported periodically or non-singularly. The event reporting service may include data instances in messages exchanged between core network devices that configures the usage and event notification.

Method and system for event reporting to third party devices

According to disclosed embodiments, as discussed below, a cell broadcasting framework is provided including receiving a request from a Network Function (NF) consumer by a service communication proxy (SCP) on a network, the request including a set of parameters, identifying a plurality of target NF producers corresponding to the set of parameters, transmitting the request to the plurality of target NF producers, receiving a plurality of successful request responses corresponding to some or all of the plurality of target NF producers, transmitting one of the plurality of successful request response to the NF consumer, and discarding all other successful request responses.

Systems and methods for emergency broadcast using delegated discovery

A system described herein may dynamically determine whether a User Equipment ('UE') is authorized to access a given Local Area Data Network (“LADN”) based on dynamically determined factors, such as temporal factors, network load factors, registration or de-registration of the UE for the LADN, etc. Updates to such polices may be further used to determine whether the UE is authorized to access the LADN. Thus, the providing of services associated with a LADN may be more dynamic and based on additional factors than a determination of whether UE subscription information (e.g., as provided by a UE information repository) indicates that a given UE has subscribed to the LADN.

Systems and methods for policy and location-based data network selection in a wireless network

Systems and methods described herein enable distribution of a Charging Function group identifier ('CHF-Group-ID') and other CHF selection data to CHF consumers during Protocol Data Unit (PDU) session establishment in a 5G network. A Unified Data Repository (UDR) is provisioned with CHF-Group-ID details for each subscriber of the network. In one aspect, during PDU session establishment, CHF consumers obtain CHF-Group-ID information as part of a subscriber profile that is provided to all CHF consumers. No additional step or hop is needed for the CHF consumers to obtain the CHF-Group-ID. Thus, regionally segmented CHFs can be implemented without replication of data between CHFs in different regional segments and without additional signaling between network functions.

Systems and methods for regional segmentation and selection of charging function

A method, a network device, and a non-transitory storage medium are described in which an application-aware scheduling service is provided. The application-aware scheduling service may be configured with bandwidth values and usability values for traffic of applications. The application-aware scheduling service may manage air interface scheduling based on the bandwidth and usability values. The application-aware scheduling service may perform packet inspection to identify an application relating to traffic. The application-aware scheduling service may be configured with a maximum bandwidth for traffic of applications.

Method and system for application-aware scheduling service

A network device may receive a request for determination of a first non-session management policy control decision for a UE, and may provide an account limits request to another network device based on the request. The network device may receive, from the other network device, account limits for the UE, and may determine a first non-session management policy control service for the UE based on the account limits. The network device may cause the UE to be provisioned with a service based on the first non-session management policy control service, and may receive a request for determination of a second non-session management policy control decision for the UE. The network device may determine a second non-session management policy control service for the UE based on the account limits, and may cause the UE to be provisioned with a service based on the second non-session management policy control service.

Systems and methods for utilizing limits to determine policy decisions not related to session management

A method, a system, and a non-transitory storage medium are described in which an discovery service is provided. The discovery service may provide a network device to request for binding information from a binding service function. The request may include information that indicates a type of policy control function. For example, the information may indicate a session management policy control function, an access management policy control function, or another dedicated type of policy control function.

Method and system for policy control function discovery service

A network device may receive a PDU session create message associated with establishing a PDU session with a user device and via a RAN, and may receive a first 5QI value and a second 5QI value associated with the PDU session. The network device may attempt to establish the PDU session with the first 5QI value and via the RAN, and may receive an indication that the first 5QI value is not supported for establishing the PDU session. The network device may cause the PDU session to be established with the second 5QI value, and via the RAN, based on the indication that the first 5QI value is not supported for establishing the PDU session.

Systems and methods for enabling an alternate quality of service for non-guaranteed bit rate flows

A system described herein may receive a first request to establish, modify, or remove a plurality of communication sessions between a User Equipment ('UE') and a network. The system may output, to a policy element of the network (e.g., a Policy Control Function (“PCF”) or a Policy Charging and Rules Function (“PCRF”)), a second request for policies associated with the UE and the plurality of communication sessions, where the second request includes a plurality of communication session identifiers that are each associated with a particular one of the plurality of communication sessions. The system may receive and enforce the requested policy information when establishing, modifying, or removing the requested plurality of communication sessions based on the received particular policy information. The system may communicate with the policy element via an enhanced interface, such as an enhanced N7 interface or an enhanced Npcf interface.

Systems and methods for enhanced session management policy interface in a wireless network

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.
