  • 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: 9848318
    Abstract: The present invention is directed towards a method for facilitating roaming tests for a club network. The method includes simulating a roamer's profile by a signaling gateway and associating with either a club network or a roaming partner network of the club network. The club network and the roaming partner network correspond to a Home Public Mobile Network (HPMN) and a Visited PMN, respectively, in case the roamer is an outbound roamer. In case the roamer is an inbound roamer, the club network corresponds to the VPMN and roaming partner network corresponds to the HPMN. The method further includes performing by the signaling gateway, one or more CAMEL capability tests on the roamer. The roaming subscriber is associated with either the club network or the roaming partner network.

  • Patent number: 9794769
    Abstract: The present disclosure is directed to a method and system for enabling and facilitating roaming of subscribers of a home public land mobile network (HPLMN) equipped with long term evolution (LTE) devices into a LTE access network of a visited PLMN (VPLMN). Voice over LTE (VoLTE) services are not supported in the HPLMN or the roaming subscribers do not have the VoLTE services. The VPLMN only supports the VoLTE services. Alternatively, the VPLMN supports VoLTE and circuit switched fall back (CSFB) to a Code Division Multiple Access (CDMA) network, but the roaming subscriber's LTE device does not support CSFB to the CDMA network. A non-VoLTE inbound roaming subscriber is registered in a home location register (HLR) as if the roaming subscriber were roaming in a VPLMN circuit switched domain. A local IMS subscription with telephony services is created and the telephony services are provided to the non-VoLTE inbound roaming subscriber.

  • Patent number: 9713053
    Abstract: The present invention is directed towards methods and systems for redirecting roaming network traffic in an LTE network. The methods include observing a registration process of a subscriber in a visited network. The methods further include, upon successful registration, sending one or more messages to the visited network to induce a re-registration attempt by the subscriber to another 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: 9572011
    Abstract: The present invention is provides towards a method and system for facilitating roaming tests for an operator in a telecommunication network. The method includes detecting a location update message of a subscriber to an HLR while switching from a first MSG/VLR to a second MSG/VLR, The method further includes holding by a value added module, a cancel location message being sent from the HLR to the first MSG/VLR. The method further includes conducting the roaming tests by the value added module, using the subscriber's profile data obtained from the first MSG/VLR. Further in the method the value added module releases the cancel location message to the first MSC/VLR.

  • 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.

  • Patent number: 9264922
    Abstract: Aspects of the present invention relate to methods, systems and computer products that guarantee the availability of basic services to subscribers during the failure of a Proxy-Profile Gateway. An independent module equipped with monitoring probes for tracking the actual location of the end-customer, an interface for controlling the Gateway availability, and an active SS7 signaling interface are also provided, in order to initiate the recovery procedures, along with a database for storing the relevant information necessary to apply the restoration procedures.
