Method and system for providing cloud subscriber identity module (SIM)
View Patent ↗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.
1. A method for mobile communication, the method comprising:
registering a client network to a cloudSIM service at a hub operator, the cloudSIM service having a plurality of roaming International Mobile Subscriber Identities (IMSIs);
provisioning on a subscriber device of the client network a set of the plurality of roaming IMSIs selected by the client network;
detecting, by the subscriber device, registration of the subscriber device to a visitor network and switching, by the subscriber device, from a client network IMSI on the subscriber device to one IMSI selected from the set of roaming IMSIs depending on a location of the visitor network;
converting, by the hub operator, signaling on the selected one IMSI to signaling on the client network IMSI; and
relaying, by the hub operator, the converted signaling from the visitor network to the client network.
2. The method of claim 1 , further comprising converting, by the hub operator, one or more signaling parameters of the signaling associated with the selected one IMSI to one or more signaling parameters of the signaling associated with the client network IMSI.
3. The method of claim 2 , wherein the one or more signaling parameters comprises at least one of Mobile Application Part (MAP) signaling, call signaling, subscriber's Mobile Station International Subscriber Directory Number (MSISDN), Customized Application for Mobile Enhanced Logic (CAMEL)/Session Initiation Protocol (SIP)/Transaction Capabilities Application Part (TCAP) transaction, data sessions and data traffic.
4. The method of claim 1 , wherein the hub operator is one of a Mobile Virtual Network Operator (MVNO), mobile network operator (MNO), having its own set of IMSIs.
5. The method of claim 1 , wherein the hub operator is located either on an on-net hub operator or on an off-net hub operator.
6. The method of claim 1 , wherein the switching to the one IMSI selected from the set of roaming IMSIs is based on at least one of a roaming location of the subscriber device, a class of the subscriber device and a predefined logic.
7. The method of claim 1 , wherein the switching to the one IMSI selected from the set of roaming IMSIs comprises changing via a configuration file.
8. The method of claim 7 , wherein the configuration file can be changed by Over the Air (OTA).
9. The method of claim 1 , further comprising changing the IMSI of the subscriber device is changed to a default IMSI via a configuration file.
10. The method of claim 9 , wherein the default IMSI is selected from a sequence of IMSIs in preference order or random order, until one IMSI is successfully registered with the visited network.
11. The method of claim 1 , wherein the switching to the one IMSI selected from the set of roaming IMSIs is switched by a Subscriber Identity Module (SIM), SIM Tool Kit (STK), application that communicates with network application via one of Unstructured Supplementary Service Data (USSD), Short Message Service (SMS) and other bearer.
12. The method of claim 1 , wherein the subscriber device is billed based on rates from the hub operator.
13. A system for mobile communication, the system comprising:
a CloudSIM hub ecosystem associated with a plurality of hub operators and client networks, wherein a client network registers to a cloudSIM service at a hub operator, the cloudSIM service having a plurality of roaming International Mobile Subscriber Identities (IMSIs);
the client network providing on a subscriber device of the client network a set of the plurality of roaming IMSIs selected by the client network;
the subscriber device detecting registration to a visitor network and switching from a client network IMSI on the subscriber device to one IMSI selected from the set of roaming IMSIs depending on a location of the visitor network;
the hub operator converting signaling on the selected one IMSI to signaling on the client network IMSI; and
the hub operator relaying the converted signaling from the visitor network to the client network.
14. The system of claim 13 , hub operator, one or more signaling parameters of the signaling associated with the selected one IMSI to one or more signaling parameters of the signaling associated with the client network IMSI.
15. The system of claim 14 , wherein the one or more signaling parameters comprises at least one of Mobile Application Part (MAP) signaling, call signaling, subscriber's Mobile Station International Subscriber Directory Number (MSISDN), Customized Application for Mobile Enhanced Logic (CAMEL)/Session Initiation Protocol (SIP)/Transaction Capabilities Application Part (TCAP) transaction, data sessions and data traffic.
16. The system of claim 13 , wherein the hub operator is one of a Mobile Virtual Network Operator (MVNO), mobile network operator (MNO), having its own set of IMSIs.
17. The system of claim 13 , wherein the hub operator is located either on an on-net hub operator or on an off-net hub operator.
18. The system of claim 13 , wherein the subscriber device switches to the one IMSI selected from the set of roaming IMSIs is based on at least one of a roaming location of the subscriber device, a class of the subscriber device and a predefined logic.
19. The system of claim 13 , wherein the subscriber device switches to the one IMSI selected from the set of roaming IMSIs comprises changing via a configuration file.
20. The system of claim 19 , wherein the configuration file can be changed by Over the Air (OTA).
21. The system of claim 13 , the IMSI of the subscriber device is changed to a default IMSI via a configuration file.
22. The system of claim 21 , wherein the default IMSI is selected from a sequence of IMSIs in preference order or random order, until one IMSI is successfully registered with the visited network.
23. The system of claim 13 , wherein the subscriber device switches to the one IMSI selected from the set of roaming IMSIs is switched by a Subscriber Identity Module (SIM), SIM Tool Kit (STK), application that communicates with network application via one of Unstructured Supplementary Service Data (USSD), Short Message Service (SMS) and other bearer.
24. The system of claim 13 , wherein the subscriber vice is billed based on rates from the hub operator.
