  • Patent number: 10028174
    Abstract: The present invention is directed towards a method and system for redirecting roaming network traffic in an LTE network. The method includes observing a registration process of a subscriber in a visited network. The method further includes sending one or more messages to the visited network to induce a re-registration attempt by the subscriber to another Radio Access Technology (RAT) network of the same visited network. The method further includes applying one or more legacy steering techniques to move the subscriber to a target visited network.

  • Patent number: 9585005
    Abstract: The present invention provides systems and methods for providing additional or modified subscriber profile information of an outbound roamer of a Home Public Mobile Network (HPMN), wherein the outbound roamer is roaming in a Visited Public Mobile Network (VPMN) in an LTE environment. The system includes a monitoring block to monitor Diameter and MAP transaction messages on S6, SI and Cx interfaces. The system includes subscriber and roamer databases storing subscriber or roamer records, wherein each record comprises at least the International Mobile Subscriber Identity (IMSI) of the subscriber or roamer. The system includes a detection block to detect whether provisioning of an alternate roaming profile is required for the subscriber or roamer, and further includes a provisioning block to provision the generated alternate roaming profile of the subscriber or roamer to LTE nodes holding a subscriber or roamer profile (i.e., MME, the IM-SSF or the SCSCF).

  • Patent number: 9445257
    Abstract: The present invention provides a method and system for mobile communication where upon detecting a change in registration of a subscriber of a 5 client network at a visited operator, the subscribers client networks IMSI is switched to a hub operators IMSI. The hub operator is selected from a cloudSIM hub ecosystem, depending on the location of the subscriber. Thereafter, a cloudSIM hub converts between the signaling on the hub operators IMSI to signaling on the client operators IMSI. Further, the cloudSIM hub relays the converted signaling between 10 the visited operator and the client operator.

  • Patent number: 9338663
    Abstract: The present invention provides a method for facilitating roaming management of a host network. The method includes obtaining at a gateway associated with the host network, signaling messages of one or more roamers. The roamers are subscribers of either the host network or one or more non-host networks. The method further includes determining by the gateway, the host network's roaming arrangement with the non-host networks, based on analysis of one or more signaling messages from the obtained signaling messages.

  • Publication number: 20150172993
    Abstract: The present invention provides a method for mobile communication facilitated by a first routing module associated with at a first network that receives call control of a subscribers call to a called number. The first routing module sends the call information of the call from the first routing module to the second routing module. The first routing module further routes the call to an alternative number upon receiving the alternative number from a second routing module associated with a second network. Finally, the second routing module further re-synchs the call to the 10 called number upon receiving call control at the alternative number.

  • Patent number: 9002320
    Abstract: Provided are methods and systems for detecting and preventing bypass fraud in telecommunication networks, primarily for detecting and preventing SIM box fraud in telecommunication networks. The methods include generating one or more test calls from a remote agent to a local agent where the remote agent can be a roaming agent or a remote dialer. The local agent is a subscriber number. The methods further include facilitating call forwarding of the test calls from the local agent to a local number. The methods include identifying the presence of bypass fraud by analyzing caller identification information of the test call received on the local number. Finally, the methods include preventing future use of a detected SIM box.

  • Patent number: 8761760
    Abstract: A method for facilitating exchange of one or more signaling messages between a client network and an HSRP network. The method includes identifying by an SPRS router associated with a client network, one or more parameters in the received signaling messages so as to determine from the parameters one or more roaming agreements that are required between the client network and the HSRP network, to allow exchange of the signaling messages. The method further includes facilitating by the SPRS router, exchange of the signaling messages between the client network and the HSRP network via one or more SPRS hubs, when the SPRS router determines absence of the required roaming agreements. The method further includes facilitating by the SPRS router, direct exchange of the signaling messages between the client network and the HSRP network, when the SPRS router determines presence of the required roaming agreements.

  • Patent number: 8478277
    Abstract: A system, method, computer product and service are provided which, when a subscriber's VoIP client is online and the subscriber's non-VoIP wireless or fixed line number is called, will automatically route the call over IP to the subscriber's VoIP client. This routing may be performed by the subscriber's wireless or fixed line home operator and can be conditioned to depend on whether the non-VoIP number is roaming or not answering.
