Abstract: A system described herein may provide a technique for the predictive determination of regions, such as registration areas associated with a wireless network, with respect to a User Equipment (“UE”) that registers with the wireless network. Such registration areas may be associated with different services, Quality of Service (“QoS”) parameters, network slices, or the like. When registering with the wireless network, the UE may receive an indication of a registration area that includes multiple tracking areas, which include a tracking area in which the UE is currently located and one or more other tracking areas in which the UE is likely to enter, as predicted based on one or more artificial intelligence/machine learning (“AI/ML”) models. The prediction may be based on the current location of the UE, UE attributes or parameters, and/or historical location information associated with the UE and/or other UEs.

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.

The method may further include determining, by the UE device, whether an application mapping rule associated with the SSP category is stored within the UE device, and obtaining, from the UE device, a quality of service level for the application flow based on the SSP category, in response to determining that the application mapping rule is stored within the UE device.

Abstract: An improved cellular network architecture enables the distribution of Radio Resource Control (RRC) inactive state to devices in a core network. A mobility manager receives subscription requests from core network devices requesting notification of user equipment (UE) transitions to RRC Inactive states. Upon receiving an RRC transition report for a UE that indicates a transition to an RRC Inactive state, the mobility manager publishes an event including data representing the RRC inactive state and a UE identifier. Subscribing network elements receive this event and can adjust operations accordingly, including temporarily suspending operations until a further RRC state change.

Abstract: A network device receives an attach request indicating that a user device is attempting a connection associated with a non-access stratum (NAS) and a particular interface, and generates a create session request that includes an indication that the connection for the user device is associated with the NAS and the particular interface. The network device provides, to a serving gateway (SGW) of the network, the create session request that includes the indication, and receives, from the SGW, a create session response that includes rules for handling the connection for the user device that is associated with the NAS and the particular interface, wherein the rules have been generated by a policy and charging rules function (PCRF) of the network. The network device provides, to the user device, an attach accept, that includes the rules, to permit the user device is to connect with the network and to utilize the rules.

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 device receives location information for a user equipment device (UE), an application identifier (ID), and a latency requirement associated with a data session involving the UE. The network device retrieves from a database, based on the UE's location information, the application ID, and the latency requirement, Multi-Access Edge Computing (MEC) selection weight values associated with multiple MEC platforms. The network device selects a MEC platform, from among the multiple MEC platforms, based on the retrieved MEC selection weight values, and causes the data session to be established between the selected MEC platform and the UE.

Abstract: Systems and methods leverage trust anchors to generate tokens which can then be used by network functions (NFs). A virtualization infrastructure manager (VIM) for a virtualized platform receives a NF software package and a certificate request token (CRT) from a management function. The NF is a virtual NF, a containerized NF, or another virtual entity (xNF) to be deployed. The CRT is digitally signed by the management function and includes a network address of a trust anchor platform and a NF profile. The VIM deploys the NF and provides the CRT to the NF. The NF obtains from the CRT the network address of the trust anchor platform, generates a certificate signing request (CSR) for a digital certificate, and submits the CSR and the CRT to the trust anchor platform. The NF receives a digital certificate from the trust anchor platform based on validation of both the CSR and CRT.
