Patent ID: 10595187

Abstract:
A Slicing Agent node is deployed between standard Home Subscriber Server (HSS) node and a Serving General Packet Radio Service Support Node (SGSN) node, a Mobility Management Entity (MME) node, or a 3rd Generation Partnership Project Authentication Authorization and Accounting (3GPP AAA) node on S6a/S6d/SWx interfaces of a Core Network. The Slicing Agent node selects the Packet Data Gateway (PGW) and communicates the identifying information of the selected PGW to SGSN/MME/3GPP AAA nodes. The PGW is selected to serve subscriber sessions based on the subscriber's profile, usage, and business needs. The Slicing Agent node can be positioned in any Core Network setup around the globe irrespective of whether it is a roaming or a non-roaming scenario for subscribers/devices having global or country-specific Subscriber Identity Modules (SIMs), without requiring any enhancements or upgrades in legacy or existing network nodes including SGSN, MME, 3GPP AAA and HSS.
