Abstract: Techniques that provide for the preservation of policy and charging for a subscriber following a user-plane element failover are described herein. In one embodiment, a method includes receiving, by a user-plane element, at least one data packet of a packet flow associated with a subscriber, wherein the at least one data packet is are received after the user-plane element has recovered from a failure; determining, by the user-plane element, whether restoration information associated with the packet flow is stored at the user-plane element; and applying one or more policies to the packet flow based on a determination that the restoration information associated with the packet flow is stored at the user-plane element, wherein the restoration information comprises a rule associated with the packet flow.

Abstract: In one embodiment, a method is performed. A first user plane entity may be associated with a user plane group comprising a plurality of user plane entities. The first user plane entity may be associated with a second user plane entity. A failure of the second user plane entity may be detected. In response to detecting the failure of the second user plane entity, the first user plane entity may be activated.

Abstract: Systems and methods are provided for providing differential treatment to user traffic involving optimized reporting of start and stop traffic. The systems and method can include detecting, at a user plane function, an initiation of a type of traffic being performed at the user plane function, providing, by the user plane function, a start event trigger of the type of traffic detected by the user plane function to a session management function, and receiving, at the user plane function, a policy associated with the type of traffic from the session management function, the policy including instructions preventing submissions of subsequent event triggers to the session management function until an end of the type of traffic, the subsequent event triggers being associated with the type of traffic detected by the user plane function.

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.
