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 cause a first traffic filter to be provided to the user equipment to enable the user equipment to route first application traffic, based on the first traffic filter, to a second user plane function and a first multi-access edge computing device associated with the second user plane function.

Systems and methods for supporting multi-access edge computing using application-based quality of service flows

A computer device may include a memory storing instructions and processor configured to execute the instructions to host a network function container that implements a microservice for a network function in a wireless communications network, wherein the network function container is deployed by a container orchestration platform; host a service proxy container associated with the network function container, wherein the service proxy container is deployed by the container orchestration platform; and configure the hosted service proxy container to apply a wireless network policy to the microservice for the network function. The processor may be further configured to intercept messages associated with the microservice for the network function using the configured service proxy container; and apply the wireless network policy to the intercepted messages using the configured service proxy container.

A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an EASDF secure service. The EASDF secure service may include a network-side service that may validate access and authorization to use a domain name system (DNS) resolver device, such as an edge application server discovery function. The network-side service may validate access and authorization of an end device based on tokens. The EASDF secure service may include an end device-side service that includes a token with a DNS query to the DNS resolver device. The end device-side service may further provide authorization regarding access and use of applications, networks, and application devices that host applications and/or assets by the end device at the end device. The end device-side service may determine access and/or authorization based on tokens and a validation procedure performed at the end device.

Method and system for EASDF secure service

Disclosure are techniques for allocating aggregation devices in a lawful intercept system. In an embodiment, a method includes maintaining a list of point of interception aggregation (PAG) functions in a network function repository function (NRF) of a cellular network upon instantiation of the PAG functions; receiving a lawful intercept (LI) request; querying the NRF to determine a respective PAG function; and associating a point of interception (POI) function with the respective PAG function.

Network discovery in a lawful intercept system

A system described herein may dynamically determine whether a User Equipment ('UE') is authorized to access a given Local Area Data Network (“LADN”) based on dynamically determined factors, such as temporal factors, network load factors, registration or de-registration of the UE for the LADN, etc. Updates to such polices may be further used to determine whether the UE is authorized to access the LADN. Thus, the providing of services associated with a LADN may be more dynamic and based on additional factors than a determination of whether UE subscription information (e.g., as provided by a UE information repository) indicates that a given UE has subscribed to the LADN.

Systems and methods for policy and location-based data network selection in a wireless network

Systems and methods described herein provide for User Equipment (UE)-initiated authentication and authorization updates to Network Slice-Specific Authentication and Authorization (NSSAA). A network device in a core network receives a message from a user device outside of the core network, wherein the message includes a request to initiate a NSSAA procedure. The network device initiates the NSSAA procedure in response to the request. The systems and methods also provide for UE-initiated authorization revocation of NSSAA.

Systems and methods for UE-initiated NSSAA procedures

A device may include a processor configured to establish a data traffic flow for a user equipment (UE) device and determine per flow descriptor attributes associated with the data traffic flow, wherein the per flow descriptor attributes identify at least a source, a destination, and a protocol associated with the data traffic flow. The processor may be further configured to determine at least one additional per flow descriptor attribute for the data traffic flow and send the per flow descriptor attributes and the at least one additional per flow descriptor attribute to a network exposure device of a core network, wherein the network exposure device is configured to communicate with servers outside the core network.

Systems and methods for exposing custom per flow descriptor attributes

A method, a device, and a non-transitory storage medium are described in which an uplink classifier and branching point service is provided. The service may include the management of user plane function devices or uplink classifier devices according to various architectures and connectivity among the user plane function devices or uplink classifier devices. The service may allow end devices situated in different locations to connect to different application service host devices and application service layer networks based on such management.

Method and system for uplink classifier and branching point service

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.

A network device may receive Network Slice Selection Assistance Information (NSSAI) and network information from network components and from a set of Integrated Access and Backhaul (IAB) nodes; generate descriptions of, or updates to the descriptions of, routing paths based on the NSSAI and the network information; and send the descriptions or the updates to the IAB nodes. The routing paths may include one or more backhaul links between the IAB nodes, and the descriptions and the updates associate each of the routing paths with one or more Single-NSSAIs (S-NSSAIs).

System and method for controlling and managing integrated access and backhaul

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.

Systems and methods for fast return to 5G RAN after fallback to another RAN

A method, a device, and a non-transitory storage medium are described in which a dual connectivity path selection service is provided. The service may select a network path for dual connectivity. The service may use mapping information that may correlate network parameters and values to dual connectivity configurations. The service may compare parameters included in a configuration request pertaining to end devices with the mapping information for selection of a dual connectivity configuration.

Method and system for dual connectivity path selection

In some implementations, a first network device may be associated with a serving gateway control plane function of a core network. The first network device may send, via a first interface, an association message to a second network device that is associated with a session management function and a packet data gateway control plane function of the core network. The first network device may receive selection information from the second network device via the first interface. The first network device may select, based on the selection information, a third network device that is associated with a serving gateway user plane function of the core network. The first network device may cause the third network device to route traffic for a packet data network session associated with a user device.

Systems and methods for facilitating connection to a data network in an interworking core network

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.

Weighted MEC selection for application-based MEC traffic steering

Systems and methods described include receiving traffic associated with a multi-access edge computing (MEC) application hosted at a MEC network; determining an Internet Protocol (IP) address associated with the MEC application, wherein the IP address indicates a priority of the traffic associated with the MEC application; modifying a header of the traffic to include the IP address associated with the MEC application; transmitting the traffic to a wireless station; and routing the traffic based on the priority associated with the MEC application.
