  • Patent number: 10785688
    Abstract: A routing platform for routing 4G and 5G mobile data traffic in a mobile core networks implementing Option-3 of 5G Non-Standalone deployment. The routing platform captures S6a Diameter messages sent between a Mobility Management Entity (MME) and a Home Subscriber Server (HSS) and examines the captured messages to determine whether a user equipment (UE) is configured for a 5G data connection. The routing platform intercepts a GTP Create-Session-Request message sent from a Serving Gateway (SGW) and determines whether the GTP message is associated with the UE previously determined to be configured for a 5G data connection. If the GTP message is associated with the UE configured for a 5G data connection, the GTP message is either sent to a dedicated 5G Packet Network Data Gateway (PGW) or the GTP message is modified so that a single PGW handling both 4G and 5G traffic can establish a 5G session for the UE.

  • Patent number: 10645230
    Abstract: A virtualized Policy, Charging, Negotiation and Enforcement Entity (PCNE) is disclosed for serving cellular traffic across multiple networks. The PCNE manages signaling and user payloads to apply policies compliant to concerned networks in real time. The PCNE provides policy control to a Home network even when its outbound subscriber traffic is locally offloaded at a Visited network or IP Packet Exchange (IPX) cloud. The PCNE protects the Visited network against capacity overuse by inbound subscriber traffic, thereby providing joint control to the Home and Visited network operators resulting in optimal use of bandwidth and resources along with consistent subscriber experience. The PCNE enables the Home network operator to implement domestic quota buckets and policies while its subscriber is roaming in the Visited network by applying differential policy and charging rules. Traffic can be offloaded to a preferred packet data gateway after enforcing the negotiated policies.

  • Patent number: 10638400
    Abstract: The specialized networking and application system includes an enforcer configured to intercept the signaling messages and select an optimal SGW, PGW, SMF/UPF and application servers in real time. More specifically, the enforcer intercepts and generates GSM MAP, Diameter, GTP-C and HTTP2/JSON signaling messages. The enforcer executes a policy to force the user devices to re-establish the data connection, thus anchoring at different SGW, PGW, SMF/UPF and application server to keep end-to-end routing path optimal, when the impacting factor changes. The enforcer can further feed its performance data and decision matrix into the analyzer and database to further optimize the decision process. Analyzer and KPI metrics databases are installed at central data centers to collect the KPI data from different probes and enforcer, calculate in real-time the optimal routing path with different decision factors considered, and interact with enforcer to update the latest optimal path status based on the data collected.

  • Patent number: 10412049
    Abstract: A packet interceptor monitors GTP traffic for control signaling and data plane traffic. The interceptor reroutes a packet by modifying its IP addresses and forwards the packet to a packet data network gateway server. The server receives the GTP-U packet, performs identification based on the synchronized GTP session information, decapsulates the GTP tunnel information from the GTP-U packet and sends to either a proxy server or the destination application server directly. The proxy server performs message filtering, stores packet contents into storage and forwards the packet out to the destination application server. The filtering function of the proxy server can be trained and enhanced with machine learning algorithms. Thus, the proxy server can automatically detect the traffic type and allow or block the packet based on the detection result.

  • Patent number: 10277586
    Abstract: This invention is a system and method for mobile authentication using HTTP redirect in GTP tunnels. The authentication procedure generates a one-time-token that returns to the Enterprise application that requests the authentication. The authentication platform injects a HTTP redirect response to the mobile device via the GTP-U tunnel that corresponds to the GTP session of the inputted-MSISDN. The HTTP redirect response carries a URL with the one-time-token as parameter. The Enterprise application authenticates the HTTP request by comparing the one-time-token in the HTTP request parameter against the value returned by the authentication platform during its authentication request API call.

  • Patent number: 10225275
    Abstract: The invention is a method of detecting malicious behavior of a network participant. Specific usage values observable at a network connectivity layer are defined. These usage values can be size of data transferred, quantity of data bursts, a quantity of IP address destinations, a network protocol being used, and/or a length of an encryption key. The invention measures the usage values for the network participant across multiple networks over a predetermined period of time and creates a statistical digital dossier representative of patterns of the measured usage values for the network participant. The invention monitors the behavior of the network participant by measuring current usage values. The current usage values are compared against the statistical digital dossier and, if a deviation beyond a predefined tolerance is detected, an alert signal is issued.
