    Abstract: An example method is provided in one example embodiment and may include receiving an indication of a radio access technology (RAT) change for a user equipment (UE); determining availability of a preferred RAT type for a policy related rule associated with the UE, wherein the policy related rule includes, at least in part, the preferred RAT type for one or more service data flows for the UE; and configuring the one or more service data flows for the UE based, at least in part, on a change in availability of the preferred RAT type following the RAT change. In at least one case, the method can include routing downlink packets to the UE using the one or more service data flows for the preferred RAT type if the preferred RAT type is available.

    Abstract translation: 在一个示例性实施例中提供了示例性方法，并且可以包括接收用户设备（UE）的无线电接入技术（RAT）改变的指示; 确定与所述UE相关联的策略相关规则的优选RAT类型的可用性，其中所述策略相关规则至少部分地包括针对所述UE的一个或多个服务数据流的优选RAT类型; 以及至少部分地基于所述RAT改变之后的优选RAT类型的可用性的改变来为所述UE配置所述一个或多个服务数据流。 在至少一种情况下，如果优选的RAT类型可用，则该方法可以包括使用用于优选RAT类型的一个或多个服务数据流来向UE UE路由下行链路分组。

    Abstract: Techniques that provide low latency traffic segregation to ensure an edge user plane (UP) is not overloaded are described herein in at least one embodiment. In at least one embodiment, a method may include determining offload of low latency traffic of a user equipment (UE) at a mobile network edge, wherein the UE has non-low latency traffic associated with a first packet data network session for an access point name; notifying the UE to request creation of a second packet data network session for the access point name; selecting an edge UP element to handle the low latency traffic for the second packet data network session; creating the second packet data network session at the selected edge UP element; and notifying the UE that second packet data network session is created.

    Abstract: Various embodiments disclosed herein provide a method for grouping user planes in 4G/5G packet cores to simplify user plane discovery and registration. In some embodiments the method includes detecting a plurality of User Planes (UPs), grouping a first subset of the UPs into a first UP group, in which each UP in the first UP group is associated with a first set of features, and allocating the first UP group to a first network service based on the first set of features associated with the first UP group and a first set of requirements of the first network service. The method further includes grouping a second subset of the plurality of UPs into a second UP group, in which each of the second UP group is associated with a second set of features and allocating the second UP group to a second network service of a plurality of network services.

    Abstract: A method, computer system, and computer program product are provided for facilitating radio access network integration with data centers. Mobile network configuration information is obtained identifying threshold latency and distance criteria and network function operating criteria. Data center information is obtained for a plurality of data centers. Latencies between a plurality of radio base stations and the plurality of data centers are determined. A primary data center and a backup data center are selected to interconnect with each radio base station based on a geographical distance between each data center and each radio base station satisfying the threshold distance and latency criteria. Network function pool configuration information is generated for the primary data center and the backup data center. A domain name system (DNS) server and a network repository function (NRF) are configured based on the network function pool configuration information.

    Abstract: A network node selectively encrypts messages between a user plane node and a control plane node in a network system. The user plane node and the control plane node negotiate a connection and indicate an encryption level for the connection. The encryption level is selected from an Information Element (IE) level, a message level, or a feature level. The user plane node and the control plane node selectively encrypt at least a portion of the messages between the user plane node and the control plane node based on the encryption level for the connection.
