Abstract: Systems and methods enable secure service-based communications in networks that use a Services Communications Proxy (SCP). A Network Function (NF) producer receives a service request including an authorization token and a signed service request object, wherein the service request originates from an NF consumer of the wireless core network and is forwarded to the NF producer via the SCP. The NF producer verifies the signed service request object and generates, after the verifying, a service response. The service response includes a signed service response object. The NF producer sends, to the NF consumer and via the SCP, the service response with the signed service response object.

Abstract: A network device may select a first user plane function for establishing, with a user equipment, a protocol data unit session with a single flow and may receive an application function trigger associated with a first new flow for a first application of the user equipment. The network device may select a second user plane function for the first new flow and may create a first traffic filter for the first new flow. The network device may cause the first traffic filter to be provided to the user equipment so that first application traffic is routed, based on the first traffic filter, to the second user plane function and a first multi-access edge computing device associated with the second user plane function.

Abstract: 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.

Abstract: A method, a network device, and a non-transitory computer-readable storage medium are described in relation to a hybrid network slicing service. The hybrid network slicing service may enable the initial configuration of a network slice according to network slice requests that may include customized and user-specified network performance criteria. The hybrid network slicing service may enable network slice requests to specify selection of network resources and use/availability based on entity-based criteria including end device and/or application specific associations. The hybrid network slicing service may optimize network slice configurations and generate network slice templates.

Abstract: Systems and methods provide reliable voice connections dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts a parameter barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.

Abstract: Systems and methods described herein provide an interface for an Network Data Analytics Function (NWDAF) to extract events from an Edge Application Server Discovery Function (EASDF) for a given network slice. An NWDAF in a core network receives an information request for an Edge Application Server (EAS) discovery service. The NWDAF sends, to an EASDF, a data request based on the information request. The NWDAF receives event data from the EASDF that is responsive to the data request and generates an analytics report based on the event data.

Abstract: A device may receive data indicating a required quality of service (QoS), and may receive radio access network (RAN) information associated with a RAN, wherein the RAN information is provided by a centralized unit (CU) of the RAN. The device may provide the RAN information to a multi-access edge computing (MEC) platform, and may receive, from the MEC platform, a QoS request that requests the required QoS. The device may provide the QoS request to the CU, and may receive a QoS response to the QoS request. The device may provide the QoS response to a policy control function (PCF) of a core network, and may receive an indication of approval of the QoS response from the PCF. The device may cause, based on receiving the indication of approval, the required QoS to be implemented by the MEC platform and network devices associated with the core network.

Abstract: A system described herein may provide a technique for the proactive failover of groups of Virtualized Network Functions (“VNFs”) based on monitoring Key Performance Indicators (“KPIs”) associated with the VNFs. KPIs associated with a particular VNF or a set of VNFs may be monitored, and a failover event indicating service degradation or imminent service degradation may be detected based on the KPIs associated with the particular VNF or set of VNFs. Additional VNFs, associated with the particular VNF or set of VNFs, may be further identified for failover from a first data center to a second data center. The additional VNFs may be identified for failover without necessarily monitoring KPIs associated with the additional VNFs, and/or based on factors in addition to KPIs associated with the additional VNFs. For example, the additional VNFs may be failed over based on the KPIs associated with the particular VNF or set of VNFs.
