Abstract: A solution for selecting an optimal user Plane entity (with Control and User Plane Separation (CUPS)) per UE during seamless roaming. In one embodiment, a method is provide that is performed by a control plane entity in a mobile core network that supports inter public land mobile network (PLMN) roaming among two or more PLMNs. The method includes obtaining a create session request from an entity in a second PLMN to which a user equipment has roamed from a first PLMN; selecting a particular user plane entity among a plurality of user plane entities based on one or more user equipment related parameters; and establishing a session with the particular user plane entity to serve user plane traffic in the mobile core network for the user equipment.

Abstract: A Centralized Self Organizing Network (C-SON) automation platform for managing a backhaul infrastructure in a telecommunication network. The C-SON automation platform monitors one or more backhaul utilization performance indicators corresponding to a backhaul infrastructure, which infrastructure transports data between one or more User Equipment (UE) connected to a small cell and a data network. The C-SON further receives subscriber data for at least one User Equipment (UE) and location data for the at least one UE from at least one Network Function (NF), and maps the at least one UE to a backhaul service flow and the small cell based on the subscriber data and the location data. The C-SON automation platform determines the backhaul utilization performance indicator exceeds a backhaul threshold limit for the backhaul service flow, and adjusts a bandwidth utilization of the backhaul infrastructure based on the backhaul utilization parameter exceeding the backhaul threshold limit.

Abstract: Methods for selecting network slice, session management, and user plane functions for user equipment (UE) are described. In one example, a control plane (CP) entity for mobility management may select a CP entity for session management for a session of a UE based on a first set of data items. The CP entity for mobility management may further select a user plane (UP) entity for the session of the UE based on a second set of data items, where second set of data items include at least some of the same data items of the first set. The CP entity for mobility management may send, to the selected CP entity, a message including an identity or indication of the selected UP entity for the session of the UE. The selected CP entity may select the identified or indicated UP entity for use in the session of the UE.

Abstract: A network function (NF) entity in a communication network receives User Plane Function (UPF) registration information for a plurality of UPFs, the registration information including a respective network attribute for each UPF. The NF entity associates each UPF with a corresponding network based on the respective network attribute, and map one or more User Equipment (UE) to the corresponding network based on a security policy to create a UE-to-network table. The NF further receives a request to establish a session for a subsequent UE, the request including a subsequent UE identifier, and determine an access permission for the subsequent UE to access the corresponding network based on the subsequent UE identifier and the UE-to-network table. The NF selects one UPF from the plurality of UPF to service the session for the subsequent UE based on the access permission, and an association between the one UPF and the corresponding network.

Abstract: A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path—defined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

Abstract: In accordance with various embodiments, a method is performed including establishing a first communication session between an application function and a user equipment assigned a first IP address. The method includes determining, by the application function, that the user equipment has changed location. The method includes, in response to determining that the user equipment has changed location, sending, by the application function, a request that the user equipment be assigned a second IP address. The method includes establishing a second communication session between the application function and the user equipment assigned the second IP address.

Abstract: Disclosed is a method that includes periodically observing packets in a user plane according to at least one key performance indicator in a configuration file to yield an observation, wherein the observation represents a closed-loop demand of resources within the user plane. The method includes adjusting, via a scheduler in the user plane and based on the observation, a binding of cores to work items. The binding between cores and work items is dynamic and changeable to improve performance. The at least one key performance indicator can include one or more of a CPU utilization, latency and packet drops. The workload allocations can include work items that are individually scheduleable functions that operate on a queue of packets within the user plane.

Abstract: Method for assisting load-balancing of subscriber sessions in a distributed mobile gateway (e.g. PGW, SGW, ePDG, or TWAG) comprising a plurality of distributed gateway instances (DGIs) is disclosed. Method includes receiving an advertisement of GTP fully qualified tunnel endpoints identifications (F-TEIDs) allocated to a first plurality of subscriber sessions, the sessions assigned to a first DGI of the DGIs. The advertisement indicates the first DGI as a recipient for data provided to the gateway and related to any of the first plurality of sessions. Method further includes storing an association between the GTP F-TEIDs of the advertisement and the first DGI, receiving a packet comprising data related to a subscriber session of the first plurality of sessions, identifying a F-TEID for the data of the received packet, identifying from stored association, that the F-TEID is associated with the first DGI, and forwarding data of the packet to the first DGI.
