Abstract: The method disclosed herein manages and generates enterprise-policy compliant guest credentials for connectivity to one or more enterprise networks. The method may include receiving a request from a guest user device to connect to a first network provided by an enterprise. The method may further comprise determining that the guest user device is authorized to access the first network when the access by the guest user is subject to a movement and roaming policy. A first credential may be provisioned for the guest user to access the first network that is consistent with the movement and roaming policy. Prior to receiving a second request to connect to a second network of the enterprise from the guest user device, provisioning a second credential, consistent with the movement and roaming policy, to the guest user.

Abstract: The present technology provides a method that includes establishing an initial output buffer depth of a modem for a data access point name (APN) interface by a network device. The network device includes a network operating system and a communication interface coupled between the network operating system and the modem. The method also includes monitoring traffic congestion of the modem during a predetermined time and receiving notification of backward congestion or notification of no backward congestion from the modem. The method further includes adjusting output buffer depth of the modem based on monitored traffic congestion.

Abstract: A system and method are provided to selectively increase the reliability for transmission of select data packets that are determined to be important or critical. When the data packets are PDUs arranged in PDU-SETs, a user plane function (UPF) receives the PDU-SETs from a content server, and, based on header information, e.g., the UPF filters the PDU-SETs according to respective reliability levels. For PDU-SETs in the highest reliability level, a manner of transmitting the PDU-SETs is modified to increase reliability of the transmission for at least part of the transmission path. For example, the redundancy of the PDUs in the PDU-SETs can be increased for one or more legs of the transmission path by generating duplicates of the PDUs, which are transmitted together with the original PDUs. Further, reliability can be increased for respective legs by transmitting the PDUs using an acknowledgement mode.

Abstract: Disclosed herein are systems, methods, and computer-readable media for generating Access Traffic Steering, Switching and Splitting (ATSSS) rules specific to different frame types of a flow, providing the ATSSS rules to a user plane function (UPF) so that the UPF detects Quality of Service (QOS) flows based on the different frame types of the flow, and transporting the different frame types of the flow on different access standards based on the ATSSS rules.

Abstract: Stateless network address privacy may be provided. A data packing may be received with an obfuscated destination address and an un-obfuscated source address. An un-obfuscated destination address may be determined based on the obfuscated destination address. An obfuscated source address may be determined based on the un-obfuscated source address. The obfuscated destination address may be replaced with the un-obfuscated destination address and the un-obfuscated source address may be replaced with the obfuscated source address. The packet may be forwarded.

Abstract: A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.

Abstract: In one aspect, a method of supporting enhanced UE policies that control which access technologies and the number of access technologies a user equipment can access beyond a single 3GPP connection and a single non-3GPP connection, the method including registering, by a user equipment, to a 3GPP network, wherein the registering includes an indication that the user equipment supports multi-access packet data unit (MA-PDU) sessions; receiving, by the user equipment, a UE policy for a first application permitting the user equipment to access at least three access technologies for communications while accessing the first application, wherein the UE policy is received from an access mobility function (AMF) of the 3GPP network; and determining, by the user equipment, one or more of the access technologies permitted in the UE policy for the first application to use to establish protocol data unit (PDU) session with the first application.

Abstract: Presented herein are techniques to provide selective network slice authentication and authorization in a mobile network environment. In one example, a method may include obtaining, by an access management element of a mobile network, a registration request from a user equipment, wherein the registration request identifies a plurality of network slices with which the user equipment seeks authentication; determining that if authentication for the user equipment with a first network slice is successful, authentication for the user equipment with one or more other network slices can be skipped; and upon successful authentication for the user equipment with the first network slice, skipping authentication for the user equipment with the one or more other network slices.

Abstract: The present disclosure is directed to migrating network traffic from a licensed spectrum to an unlicensed spectrum within the same radio access technology (RAT). In one aspect, a method includes identifying a user device connected to a cellular wireless access technology, over a licensed spectrum; determining whether a condition for switching network traffic associated with the user device to an unlicensed spectrum is triggered; in response to determining that the condition is triggered, determining an unlicensed spectrum to move the network traffic to, the unlicensed spectrum being within a same cell as the licensed spectrum or in a different cell compared to a cell in which the licensed spectrum is; and migrating at least a portion of the network traffic to the unlicensed spectrum while maintaining network connectivity of the user device over the cellular wireless access technology.

Abstract: Systems, methods, and computer-readable media are provided for on-boarding network devices onto a private 5G network. An example method can include discovering a first private 5G network upon the network device being turned on, authenticating, at the network device, the network device, downloading a second network profile from an SM-DP+ server of a second private 5G network, and on-boarding the network device to the second private 5G network.
