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 first network device may receive, from a second network device, a first policy control create request and may provide, to the second network device, a common policy control request trigger. The first network device may receive a second policy control create request associated with a user equipment (UE) and may cause a UE policy to be provided to the UE. The first network device may receive, from a third network device, a third policy control create request and may provide a network device policy to the third network device. The first network device may receive, from the second network device, a policy control update request based on the common policy control request trigger and may generate an updated UE policy or an updated network device policy based on the policy control update request.

Abstract: A network repository function (NRF) device may receive first locality and priority information concerning a first network function device from the first network function device and may receive second locality and priority information concerning a second network function device from the second network function device. The NRF device may update a data structure based on the first locality and priority information and the second locality and priority information. The NRF device may receive a query concerning a locality from a third network function device and may search the data structure based on the query to identify network function device information associated with the locality. The NRF device may send the network function device information to the third network function device.

Abstract: A method, a device, and a non-transitory storage medium are described in which a policy control event exposure service is provided. The service may include a policy control event exposure service that supports quality of service (QoS)-based event subscription and access and mobility (AM)-based event subscription. The service may notify network function consumers when a QoS-based event or an AM-based event occurs.

Abstract: 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.

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 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.

Abstract: A method for controlling bearers in a core network includes receiving, from a user equipment (UE) device, a request for access to network resources, where the core network is coupled with a primary radio access technology (RAT) and a secondary RAT. The method includes determining an access point name (APN) RAT access restriction in response to the received request, where the APN RAT access restriction associates an APN with a corresponding RAT, where the corresponding RAT comprises at least one of the primary RAT or the secondary RAT. The method also includes assigning a radio bearer based on the determined APN RAT access restriction, wherein the assigned radio bearer exchanges data via the corresponding RAT; and identifying, to a master node, the assigned radio bearer for exchanging data between the UE device and a device specified by the APN via the corresponding RAT.
