  • Patent number: 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.

  • Patent number: 10932166
    Abstract: Use of available bits in the TEID field of the GTP header to hold information needed to recreate at least a partial state of the session, enough for it to be routed, without waiting for a full state update. The GTP PDU contains the IP Payload with the source and destination IP addresses. The embodiments use that information and the coded TEID bits to provide sufficient routing information so that the packet can be routed without the full state. The TEID is coded to include bits identifying the APN and bits identifying the QCI of the session. A bit can be used to indicate drop if the full state not available. The remaining bits are used to identify unique user sessions. Some of the TEID bits can be encoded with the charging ID. Because sufficient routing information is provided in each packet, a backup gateway does not need to checkpoint.

  • Patent number: 10873851
    Abstract: Each UE in a mobile data network is assigned two different addresses, one a common IP address used downstream of the P-GW and the other a new IP address used upstream with the router and unique to the data processing node. The node changes the IP address of the UE in either direction as a packet passes through the P-GW. The use of an IP range unique to each node or data processing unit allows the upstream router to route downlink packets directly to the node containing the UE context, so that forwarding of packets between nodes is greatly reduced, if not eliminated. By getting rid of this inter-node forwarding, the data plane can scale to much greater limits.

  • Patent number: 10506467
    Abstract: An intelligent system and a method in a packet network to utilize the radio network resource and the core network resource in an optimized way so that more high priority, critical devices are granted access to the network while throttling the low priority, non-critical devices with the same given resource. The system collects all the necessary information from the signaling exchange between the radio access network and the core network and takes the device subscription characteristics and statically or dynamically defined throttling behavior rules into consideration to choose the optimal behavior to handle the requests from devices at any given time including deciding to reject the requests for certain types of devices under certain network conditions while granting the requests for other types of devices.

  • Patent number: 10225232
    Abstract: A system and an algorithm in a mobile core network to distribute the data load across multiple data processing entities. The system is seen as having one data plane entity to the external entities like routers; hence the system can scale without needing to update the external nodes. In general when a data plane processing entity is added or removed, a new distribution rule is provided to the remaining data plane processing entities. Only after some number of sessions have been migrated does the new distribution get provided to the data distribution entities. This delay allows sufficient sessions to be migrated to minimize the overall number of packets that have to be forwarded for processing. This benefit can be maximized by taking advantage of cellular network's idle mode behavior and by migrating the sessions while they are in idle mode.
