A User Equipment ('UE') described herein may connect or request connection to a base station of a wireless network. The base station may implement multiple frequency bands, and connecting or requesting connection to the base station may include connecting or requesting connection via a particular frequency band of the multiple frequency bands. The UE may provide an indication of the particular frequency band to a core of the wireless network. The core may select a set of parameters for communications between the UE and the wireless network based on the indication of the particular frequency band. Additionally, or alternatively, the core may provide an indication of the particular frequency band to a device that provides a service to the UE via the wireless network, and the device may select parameters for the service based on the indication of the particular frequency band.

Systems and methods for real-time frequency band monitoring in a wireless network

A method may include receiving, by at least one network device and from a user device, a registration message including a service identifier and at least one of a network slice identifier or a network slice token. The method may also include determining, based on information included in the registration message, whether the user device is authorized to use a network slice associated with the service identifier. The method may further include setting up a data session to be serviced by the network slice, in response to determining that the user device is authorized to use the network slice.

Systems and methods for network-based slice access authorization

A network device receives a network service request, for network service in a mobile network, from a user equipment device (UE), where the network service request includes a first service identifier (ID) and a subscription concealed ID (SUCI). The network device sends, to a Network Function (NF) in the mobile network, a SUCI deconcealment request that includes the SUCI. The network device receives, from the NF, a deconcealed Subscription Permanent Identifier (SUPI) decrypted from the SUCI. The network device verifies a validity of the first service ID for the deconcealed SUPI, and sends a service authorization response to the UE based on verification of the validity of the service ID from the UE.

Network exposure function (NEF) for SUCI-based UE-initiated service authorization

A system described herein may receive a request to establish a communication session between a core network and a User Equipment ('UE'), determine that the requested communication session is associated with one or more admission control options and receive, from the UE, a selection of a particular admission control option of the one or more admission control options. The system may identify one or more actions associated with the particular admission control option. The one or more actions include rejecting the request to establish the communication session, or accepting the request to establish the communication session. The system may perform the one or more identified actions associated with the particular admission control option. The system may include an interface between an Access and Mobility Management Function (“AMF”) of the core network and a Network Slice Access Control Function (“NSACF”) of the core network.

Systems and methods for application function-initiated admission control for a core 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

Techniques for packet flow description (PDF) management are disclosed. In one embodiment, a method is disclosed comprising receiving, by a network exposure function (NEF), a packet flow description (PFD) management request via an application function (AF), the PFD management request, the PFD management request comprising application identification information identifying an application, using, by the NEF, the application identification information to identify a set of unified data repositories (UDRs) affected by the PFD management request, and instructing, by the NEF, at least one UDR of the set of UDRs to make a PFD change to the identified application's application data in accordance with the PFD management request.

Packet flow description (PFD) management method and apparatus

A quality of service traffic steering approach for multi-access edge computing (MEC) environments is disclosed. In an embodiment, a network exposure function (NEF) or similar device (e.g., MEC controller or orchestrator) monitors a quality of service (QoS) of a data session between a user equipment (UE) and an application. The NEF then can determine when the QoS of the data session does not meet a requested service level agreement (SLA). When the SLA is not met, the NEF identifies a MEC host that meets the SLA using a database of MEC applications. Based on the identified MEC host, the NEF re-routes the data session to the MEC host.

Dynamic quality of service traffic steering in a multi-access edge computing environment

A device may create a list of identifiers for base stations that support a fixed wireless service for a user device. The device may receive a first identifier of a first base station associated with a first attach request of the user device. The device may enable the fixed wireless service for the first base station for the user device when the first identifier is included in the list of identifiers. The device may disable the fixed wireless service for the first base station for the user device when the first identifier is not included in the list of identifiers.

Systems and methods for controlling provision of fixed wireless services utilizing a list of authorized identifiers

A system may receive a request to perform a firmware update on an Internet of Things (IoT) device and determine whether the IoT device is capable of switching from a first mode to a second mode. The IoT device sends and receives data via first channels when the IoT device is operating in the first mode and the IoT device sends and receives data via second channels when the IoT device is operating in the second mode. The system instructs the IoT device to switch to the second mode in response to determining that the IoT device is capable of switching to the second mode and sends the firmware update to the IoT device while the IoT device is in the second mode. The system determines that the firmware update has been completed and instructs the IoT device to switch from the second mode to the first mode when the firmware update has been completed.

Over-the-air firmware updates for dual-mode internet of things devices

A system described herein may provide a technique for an inter-segment Network Function ('NF') discovery procedure in a network that includes multiple discrete network segments. The network segments may each include a respective set of NFs. An NF discovery request may include discovery parameters such as an identifier of a User Equipment (“UE”). Network segments may be checked in a sequential or hierarchical manner to determine whether a respective network segment includes an instance of the requested NF that matches the discovery parameters (e.g., is associated with the UE identified in the NF discovery request).

Systems and methods for network function discovery in a segmented network

A method, a device, and a non-transitory storage medium are described in which a network slice usage service is provided. The network slice usage service may allow a network device to obtain a network slice usage value of a network slice. The network device may calculate a network slice load value based on the network slice usage value. The network device may also provide the network slice load value to other network devices of a core network.

Method and system for network slice usage service

A device, located in a core network associated with a radio access network (RAN), may include a processor configured to expose services or capabilities to application servers outside the core network, wherein the device is located in a core network associated with a radio access network (RAN). The processor may be further configured to receive a subscriber identifier message from a gateway device that established a connection to a user equipment (UE) device via the RAN, wherein the subscriber identifier message includes information identifying the UE device; receive a request from an application server associated with the connection for the information identifying the UE device; and provide the requested information identifying the UE device to the application server, in response to receiving the request from the application server.
