Abstract: Systems and methods described herein provide binding support function (BSF) service registration and discovery for environments using oversubscribed network addresses. A network device in a core network receives a registration request from a binding support device. The registration request includes a binding group identifier associated with the binding support device. The network device stores, based on the registration request, a profile for the binding support device that includes the binding group identifier and receives, from a policy control device, a discovery request for a that includes a unique identifier of user equipment (UE) device. The network device provides, to the policy control device, a response to the discovery request that identifies the binding support device.

Abstract: A network device of a core network may maintain a mapping table that maps core network slices with quality of service (QoS) class identifiers (QCIs) based on service profile identifiers (SPIDs), and may receive, from a user device, a request for service with a particular QCI included in the QCIs of the mapping table. The network device may identify a particular SPID of the SPIDs in the mapping table based on the particular QCI of the service, and may generate a flow request based on the particular SPID. The network device may cause the flow request to be provided to a radio access network (RAN) associated with the user device, to cause the RAN to select a RAN slice for provision of the service to the user device.

Abstract: A device may include a processor configured to maintain a plurality of session management entities (SMEs) for a core network associated with a radio access network (RAN). The processor may be further configured to establish a communication session using a first SME, of the plurality of SMEs; store session data for the communication session in a communication session database accessible by each of the plurality of SMEs; receive, using a second SME of the plurality of SMEs, a message associated with the communication session; retrieve, using the second SME, session data for the communication session from the communication session database, based on receiving the message; and process, using the second SME, the message using the retrieved session data.

Abstract: 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.

Abstract: A device may include a processor configured to determine, in a core network associated with a radio access network, that a user equipment (UE) device, associated with an enterprise, has attached to the core network via a base station in the radio access network. The processor may be further configured to obtain a mapping between a plurality of applications associated with the enterprise and a plurality of Quality of Service (QoS) classes; identify an application, of the plurality of applications, for a communication session associated with the UE device; select a QoS class, from the plurality of QoS classes based on the identified application and the obtained mapping; and process messages associated with the communication session based on the selected QoS class.

Abstract: 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.

Abstract: Embodiments described herein may provide for the return (e.g., reconnection) of a User Equipment (“UE”) to a first radio access network (“RAN”) to which the UE was connected, after the UE has been redirected to a second RAN based on the occurrence of an event. The event may include a voice call placed by or to the UE. The return of the UE to the first RAN may occur based on the occurrence of another event, such as the voice call being terminated.

Abstract: A method, a system, and a non-transitory storage medium are described in which an binding information service is provided. The binding information service may include applying one or multiple criteria to binding information stored by a binding service function. The binding information service may identify candidate binding information instances that may need deletion based on the one or multiple criteria. The binding information service may interrogate a policy control network device as to the current registrability of the binding information. The binding information service may delete or maintain the binding information based on a result of the interrogation. The binding information service may also include directing the binding service function to delete binding information based on one or multiple criteria. The one or multiple criteria may relate to the age of the binding information or a last time the registrability of the binding information was confirmed.

Abstract: A network device of a core network may maintain a mapping table that maps core network slices with quality of service (QoS) class identifiers (QCIs) based on service profile identifiers (SPIDs), and may receive, from a user device, a request for service with a particular QCI included in the QCIs of the mapping table. The network device may identify a particular SPID of the SPIDs in the mapping table based on the particular QCI of the service, and may generate a flow request based on the particular SPID. The network device may cause the flow request to be provided to a radio access network (RAN) associated with the user device, to cause the RAN to select a RAN slice for provision of the service to the user device.

Abstract: A device receives a call invitation message with a Session Description Protocol (SDP) offer for establishing a call between a calling party and a called party and obtains a set of network fallback rules associated with the called party. The device determines, based on the set of network fallback rules, whether to reject the call and avoid network fallback from a first wireless network to a second wireless network. The device sends, based on the determination, a call denial message without an SDP answer, to reject the call and avoid the network fallback.

Abstract: 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.

Abstract: 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).

Abstract: A network device receives, from a requester, an access token request associated with subscribing a consumer network function (NF) to a resource provided by a producer NF, where the access token request includes a notification identifier identifying where the consumer NF is to receive content and/or notifications, associated with the resource, from the producer NF. The network device validates the requester and generates an access token and an access token response based on successfully validating the requester. The network device signs the notification identifier as a component of the access token response and sends the access token response, with the signed notification identifier, to the requester for use in requesting a subscription to the resource for the consumer NF from the producer NF.

Abstract: A network device receives a first message that includes an identifier (ID) of a first User Plane Function (UPF), serving a first device, in a wireless network, where the first message invites a second device to engage in a session with the first device and where the first UPF supports packet routing and forwarding within the wireless network. The network device extracts the ID of the first UPF from the first message and determines a closest media resource function (MRF) to the first UPF, where the MRF processes and routes media streams between devices. The network device assigns the determined MRF as an anchor, in a network path between the first device and the second device, for processing and routing of media streamed between the first device and the second device.
