Patent ID: 11323410

Abstract:
When a user equipment (UE) provides a new request to a serving gateway (S GW), the S GW augments domain name system (DNS) requests and provides them to a public DNS, with the augmentation providing indications of the requested function. The public DNS responds by providing the IP address of a simplified packet data network (PDN) gateway (P GW) close to the UE location. The P GW forwards communications to the nearest instance of an endpoint providing the requested service or function. In embodiments, some of the functions of the P GW are shifted to other devices in the mobile core, devices that are already local. The simplification of the P GW allows the P GW to be virtualized and moved to a general-purpose server location. Existing information present in the data path is used to provide encryption of portions of the General Packet Radio Services (GPRS) Tunneling Protocol (GTP) connection, allowing the location of the P GW to be optimized in a virtual server data center, as the data path is now secure.
