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.

Abstract: A Tokenized Communication Service Provider (TCSP) for providing secure messaging between a consumer and a message sender without exposing the consumer communication preferences and Personally Identifiable Information (PII) to the message sender. TCSP issues a communication token to be used for the communication between the consumer and the message sender. Consumer authorization is recorded in a blockchain ledger and a Zero Knowledge Proof mechanism is used to establish that the TCSP possesses the consumer contact information and authorization. The consumer authorization is revocable by the consumer, and the revocation is recorded in the blockchain ledger.

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.

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.

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.

Abstract: Application of streaming machine learning clustering algorithms enables finding clusters of messages (P2P text messages, WHATSAPP, tweets) sharing the same content. Such clusters may be analyzed for finding out offensive messages, unwanted or spam messages, and rumors and take corrective actions as needed. The solution enables visualization of data and/or messages and identification of clusters as the solution works on the data and aggregates data into clusters over time intervals. Corrective actions may be applied on selected clusters based on visualized data clusters or by automated application of defined rules.

Abstract: A cross-network call identifying function for identifying instances of international call interconnect bypass telecommunications fraud. The cross-network call identifying function access call detail records of both the terminating network and the originating network. The cross-network call identifying function identifies an outgoing international phone call from a caller within the originating network to a callee within the terminating network. The call detail records of the terminating network are querried for an incoming call with a matching callee call identifier. Time information of the outgoing call and the incoming call are compared to determine whether there is a match. If the callee call identifiers and time information match, but the incoming phone call is recorded as a local call, then the incoming call is identified as an instance of international call interconnect bypass fraud.

Abstract: A method of sending a targeted SMS message to a roamer. A messaging platform accesses signaling traffic between the roamer's user equipment, a visited network operator, and a home network operator. The messaging platform obtains the roamer's current location from the signaling traffic with the visited network operator and extracts demographic information associated with the roamer from data received from the home network operator. The messaging platform queries a messaging database for prestored messages corresponding to the roamer's current location. The messages corresponding to the roamer's current location are filtered based on the roamer's demographic information to identify the targeted message for the roamer, which is then transmitted to the roamer's user equipment.

Abstract: A method for detecting SMS messaging service interruptions by classifying SMS messages as delivered or undelivered based upon the receipt of a successful conversion message within a predetermined time period. A current conversion rate is calculated for each network operator partner and destination network pair and the current conversion rate is compared against a reference conversion rate to identify a decrease in the conversion rate of the SMS messages. If the conversion rate decrease exceeds a predefined value, the channel between the network operator partner and the destination network pair is flagged and subsequent SMS messages are routed to end users via an alternative destination network.

Abstract: This invention is a system and method for a high-performance Diameter Routing Agent (DRA) platform with a three-tier architecture. The DRA platform consists of a Diameter Connection Router (DCR), a Diameter Load Balancer (DLB), and multiple DRA Instances. DCR is a front-end to all external Peers and distributes Diameter connections to a DLB. DLB is a Diameter transaction load balancer and distributes individual Diameter transaction to a DRA. DRA is a Diameter Routing Agent to implement business logic to determine routing of an incoming request to a destination peer as well as message mediation. A public Internet Protocol (IP) address of the DCR is exposed to the external peers as a single point of contact between the peers and the computer network, wherein an internal topology of the computer network remains hidden from the peers.

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.
