Abstract: A system for supporting the deployment of an embedded subscriber identification module (eSIM) provisioning management system on the ES3 interface between Subscription Manager Data Preparation (SM-DP) of a target mobile network operator (MNO) and Subscription Manager Secure Routing (SM-SR) of a current MNO. A SM-Proxy implements a SM-SR functionality on a first interface towards the SM-DP, and implements a SM-DP functionality on a second interface towards the SM-SR. A hosted SM-DP implements a RESTful API to receive SIM profile information from a provisioning server in the target MNO's network. An Agreement Management system controls a set of eSIM provisioning rules. A Service Portal enables the MNOs to manage their eSIM provisioning rules across their MNO partners.

Abstract: A networking and application system for handling the data communications protocols in the mobile packet core network. General Packet Radio Service (GPRS) Tunneling Protocol (GTP) has a control plane for control signaling (GTP-C) and a data plane for user data (GTP-U). A GTP Switch interfaces with Serving GPRS Support Node (SGSN) and/or serving gateway (S-GW). The GTP Switch provides Interment Protocol (IP) address manipulation to hide the topology of distributed control plane and data plane instances. The GTP Switch also implements dynamic node selection to route the control signaling and data plane traffic to different instances, hosted on separate servers, thus enabling higher flexibility in the network routing path optimization and scalable and elastic handling of the data traffic.

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.

Abstract: A method and system of providing a roaming data service to a User Equipment (UE) that requires a dual attachment to a Packet Switched (PS) network for the data service and a Circuit Switched (CS) network for a voice service, but the visited network is a data-only PS network. When the UE sends a dual attach request, the visited network communicates with the home network via a Diameter Agent to obtain the UE's PS profile needed to complete attachment of the UE in the visited network for data services. To enable CS attach of the UE with the visited network, a custom function, titled a SGs-Agent, is deployed. The SGs-Agent provides a predefined CS profile to the visited network, thereby enabling the UE to complete the CS attach with the visited network. The visited network provides data services to the UE, but the voice services are denied.

Abstract: A method of providing voice call, data, and SMS services to a user equipment roaming in a 2G/3G visited network and subscribed to an LTE home network. An Interworking Function communicates with both the visited network and the home network. The Interworking Function translates between Mobile Application Part (MAP) protocol used by the 2G/3G visited network and Session Initiation Protocol (SIP) used by the LTE home network. The Interworking Function establishes both a MAP Registration with the 2G/3G visited network and also a SIP Registration with the LTE home network, thereby enabling provision of voice call, data, and SMS services to the roaming UE.

Abstract: A method of establishing connectivity between a mobile network operator (MNO) and a machine type communications (MTC) service provider. A machine type communications interworking function (MTC-IWF) Proxy is hosted on an IPX network service. MTC-IWF Proxy is connected to a MTC-IWF of the MNO and is also connected to a Service Capacities Center (SCS) of the MTC service provider. MTC-IWF Proxy connects to the MNO and the MTC service providers via trigger-service provider (Tsp) interface. Identity mapping services are provided between a first set of subscriber identifiers used by the MNO and a second set of subscriber identities used by the MTC service provider. The MTC-IWF Proxy hides the internal topology and relays signaling protocols used over a Tsp interface, thus enabling the MTC service providers and MNOs communicate without modifying their internal signaling protocols.

Abstract: A roaming method that enables the home network (HPMN) to use S8 Home Routed (S8HR) model for out-bound roaming while the visited network (VPMN) uses Local Breakout (LBO) model for in-bound roaming. An IMS Roaming Gateway (IR-GW) establishes an IMS bearer between the IR-GW and the home network's Packet Data Network Gateway (P-GW). The IR-GW replaces the source IP address on the SIP-Register message with the client IP address assigned to the UE by the HPMN P-GW. Upon receiving a SIP-Response message responsive to successful authentication of the UE with the HPMN, the IR-GW inserts its own IP address into the SIP-Response message and forwards it to the UE. IR-GW performs network address translation (NAT) between the source IP assigned to the UE by the VPMN and the client IP assigned to the UE by the HPMN.
