  • Patent number: 8254918
    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: 7912464
    Abstract: A SIMM System and method is provided that supports many Mobile Subscriber Integrated Service Digital Network (MSISDN) numbers on a mobile device. The mobile device includes one Subscriber Identity Module (SIM) and one International Mobile Subscriber Identity (IMSI). The SIMM system includes at least one signal gateway that supports the use of numerous MSISDN numbers by the mobile device. The signal gateway couples among components of the public mobile networks to which the MSISDN numbers correspond. The signal gateway connects calls between the mobile device and a first public mobile network using a first MSISDN where, for example, the first public mobile network is in a first country. Likewise, the signal gateway connects calls between the mobile device and a second public mobile network using a second MSISDN where, for example, the second public mobile network is in a second country.

  • Patent number: 7873358
    Abstract: The present invention provides a method for redirecting roaming traffic of a roamer associated with an HPMN and currently roaming in a first VPMN. The method includes detecting by a detection unit coupled to the first VPMN, a registration attempt of the roamer at a second VPMN, upon receipt of a first registration cancellation message of one or more registration cancellation messages, sent by the HPMN. Finally, the method includes causing the HPMN to send a registration response message to a VLR associated with the second VPMN, to thwart the registration attempt of the roamer at the second VPMN, by sending one or more registration messages to the HPMN from a redirection unit coupled to the first VPMN. The redirection unit further facilitates the roamer's mobile communication when the roamer's handset gets stuck in the second VPMN.
