A system described herein may receive, from a policy element of a core of a wireless network, a set of triggers associated with a plurality of radio frequency ('RF') bands implemented by a radio access network (“RAN”). The system may identify that a User Equipment (“UE”) is connected to the RAN via a first RF band, and may identify a subsequent connection of the UE to the RAN via a second RF band. The system may identify that a particular trigger, of the set of triggers, is satisfied based on the subsequent connection of the UE to the RAN via the second RF band, and may indicate, to the policy element, that the particular trigger has been satisfied. The policy element may output a second set of UE policies for communications between the UE and the core of the wireless network based on the satisfaction of the particular trigger.

Systems and methods for user equipment policy updates based on radio frequency connection characteristics

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.

A base station may allocate wireless communication resources to configure a synthetic wireless communication signal for use as a radar signal. The synthetic wireless communication signal may be configured according to a wireless communication protocol of a wireless communication network that is associated with the base station. The base station may transmit, from an antenna and toward an area associated with the base station, the synthetic wireless communication signal. The base station may detect a reflected signal that is associated with the synthetic wireless communication signal. The base station may process the reflected signal to generate radar data; and perform an action associated with the radar data and the area.

Systems and methods for enabling and utilizing radar capability on a wireless communication

A method may include transmitting multiple antenna beams to an unmanned aerial vehicle (UAV) and determining a location of the UAV. The method may also include identifying a network slice to service the UAV, assigning the identified network slice to the UAV and performing antenna beam management for the UAV while the UAV is in flight.

Unmanned aerial vehicle detection, slice assignment and beam management

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

In some implementations, a network device (e.g., an Internet protocol multimedia subsystem (IMS) application server (IMS-AS) may receive, via a first communication interface, from a call session control function (CSCF) device, a request to register for an Internet protocol multimedia subsystem (IMS) service. The network device may provide via a second communication interface between the network device and a unified data management (UDM) device, and to the UDM device, a request for IMS service information associated with the IMS service. The network device may receive based on providing the request for IMS service information, via the second communication interface, and from the UDM device, IMS service information. The network device may cause, based on the IMS service information, the IMS service to be provided to a user device associated with the request to register for the IMS service.
