Title: Method and system of multi-terminal mapping to a virtual sim card

Description:
TECHNICAL FIELD 
     The present disclosure generally relates to the field of communication technology, and more particularly, to a multi-terminal mapping system associated with a virtual Subscriber Identity Module (SIM) card and the method thereof. 
     BACKGROUND 
     Presently, with the rapid development of communication technology and mobile terminals, even ordinary users can possess a number of mobile devices, such as multiple mobile phones and tablet PCs. As a result, users have found the needs to share a single SIM card among multiple mobile terminals. For a user using a physical SIM card, if a SIM card is to be shared among multiple mobile terminals, it is necessary to manually unmount the physical SIM card from one terminal and install the SIM card into another mobile terminal. Manually uninstalling and installing a physical SIM card can be a hassle. In particular, if the user has to frequently switch a single physical SIM card among multiple mobile terminals, the switching operation can become an extremely annoyance for the user. 
     SUMMARY

     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , which is a block diagram of a first exemplary multi-terminal mapping system  1  based on a virtual SIM card according to an embodiment of the disclosure. As shown in  FIG. 1 , the multi-terminal mapping system  1  of the virtual SIM card includes a terminal device  100 , a cloud  200 , and a server  300 . 
       FIG. 2  is a block diagram of terminal device  100  as illustrated in the embodiment of the multi-terminal mapping system  1  in  FIG. 1 . As shown in  FIG. 2 , terminal device  100 , which may include a mobile phone, a wearable device, a tablet, a computer or an vehicle-based system, further includes a communication unit  110  configured to transmit a request for connecting to a virtual SIM card and receive a SIM-card-connection-success message or a SIM-card-connection-failure message; management unit  120  configured to connect to the virtual SIM card after communication unit  110  receives the SIM-card-connection-success message. 
     It can be understood that terminal device  100  also includes a processor and a memory, the memory may be configured to store communication unit  110  and management unit  120 , and the processor may be configured to execute the functions of communication unit  110  and management unit  120 . 
       FIG. 3  is a block diagram of server  300  according to the embodiment as illustrated in  FIG. 1 . As shown in  FIG. 3 , server  300  of the present disclosure includes: a communication unit  310  configured to receive a request for subscribing to a virtual SIM card, receive a request for connecting to the virtual SIM card, and receive a payment result notification from a third-party payment server as a feedback to a payment request. In some embodiments, both the payment request and the payment result notification include an order number, and the request for subscribing to the virtual SIM card includes a user ID and a virtual SIM card identifier. Server  300  also includes an order unit  320  configured to generate an order based on the user ID and the virtual SIM card identifier and send the order number of the order to terminal device  100 . In some embodiments, the order includes the user ID and the virtual SIM card identifier. Server  300  additionally includes a determination unit  330  configured to determine whether the payment is successful based on the payment result notification. If the payment is successful, determination unit  330  may be configured to obtain the user ID and the virtual SIM card identifier in the corresponding order based on the order number in the payment result notification, establish a subscription relationship between the user ID and the virtual SIM card identifier, and transmit a subscription-success message to terminal device  100 . If the payment is not successful, determination unit  330  may be configured to transmit a continue-to-pay or a cancel-the-order message. Determination unit  330  may be further configured to determine whether the request for connecting to the virtual SIM card has been authenticated, if the request for connecting to the virtual SIM card is authenticated, send a connection-request-success message to terminal device  100  to connect terminal device  100  and the virtual SIM card; and if the request for connecting to the virtual SIM card is not authenticated, send a connection-request-failure message to terminal device  100 . By determining the subscription relationship between the user ID and the virtual SIM card identifier, the disclosed system may ensure that only an authorized user, i.e., a user who has subscribed to the virtual SIM card, can use the virtual SIM card. 
     In some embodiments, determination unit  330  may be configured to receive a request for connecting to the virtual SIM card from terminal device  100  and subsequently generate a random code based on the received request and transmit the random code to the virtual SIM card. The virtual SIM card may generate a result based on the received random code and may transmit the result to server  300  to cause server  300  to compare the received result with pre-stored information to determine whether they match. When the received result matches the pre-stored information, server  300  may transmit a connection-request-success message to terminal device  100  to connect terminal device  100  with the virtual SIM card. When the received result does not match the pre-stored information, server  300  may transmit a connection-request-failure message to terminal device  100 . 
     It can be understood that server  300  also includes a processor and a memory, the memory may be configured to store communication unit  310 , order unit  320 , and determination unit  330 , and the processor may be configured to execute the functions of communication unit  310 , order unit  320 , and determination unit  330 . 
     In some embodiments, the above-described user ID includes one or more of: a username; gender; ID card information; and fee account information. The above-described SIM card identifier may include one or more of: a card number; a secret key, and authorization information. In some embodiments, terminal device  100  may include: a mobile phone, a wearable device, a tablet, a computer or a vehicle-based system. In some embodiments, the communication network between terminal device  100  and server  300  can include one of: a carrier network (e.g., 5G/4G/3G networks etc.), a wireless network, such as Wi-Fi, or a wired network (e.g., a broadband network). 
     Referring to  FIG. 4 , which shows a schematic diagram illustrating a connection between terminal device  100  and cloud  200  in  FIG. 1  according to an embodiment of the disclosure. As shown in  FIG. 4 , each of the virtual SIM cards (i.e., virtual SIM card  1 , virtual SIM card  2 , . . . , virtual SIM card n) is stored in a designated space in cloud  200 , and the location of each of the virtual SIM cards has a location number which corresponds to the card number of the corresponding virtual SIM card so that a user of a virtual SIM card can easily locate that virtual SIM card. As can be seen in  FIG. 4 , a number of different types of terminal devices, such as mobile phones, wearable devices, networked smart in-vehicle systems, and Internet of Things smart devices can simultaneously read the same virtual SIM card in cloud  200 , that is, a single virtual SIM card can be mapped to multiple and different types of terminal devices. This system configuration may allow a user to virtualize a terminal device having user&#39;s own attributes from different regions and using different devices, and subsequently use the terminal device having user&#39;s own attributes to communicate. Note that, even if the user&#39;s phone is not with the user, the user can user a wearable device, a networked smart in-vehicle system, and other devices having the same attributes as the user&#39;s phone as the user&#39;s identification for communication. Because each of the terminal devices uses the same virtual SIM card, each of the terminal devices can have the same attributes. To distinguish the multiple terminal devices sharing the same virtual SIM card, the terminal devices can be distinguished based on their terminal types, locations, and utilities. For example, for a number of smart devices of user John sharing a single virtual SIM card, it is possible to distinguish these smart devices based on the device types, e.g., John&#39;s mobile phone, John&#39;s smart eyeglasses, John&#39;s vehicle communication system, etc. to distinguish the different devices. In some embodiments, multiple terminal devices sharing the same virtual SIM card can share cloud resources such as phone book, photos, videos, and other cloud-based information. As a result, when a particular terminal device, such as the mobile phone is not nearby or having trouble, the user can connect with the same virtual SIM card using another terminal device such as the tablet PC, thereby achieving the same communication capability and document review. 
       FIG. 5  presents a flowchart illustrating a method of mapping multiple terminals to a virtual SIM card according to an embodiment of the disclosure. The method of mapping multiple terminals to a virtual SIM card includes the following steps: 
     Step S 1 : store one or more virtual SIM cards in cloud  200 ; 
     Step S 2 : send a request for connecting to a virtual SIM card, and the request for connecting to the virtual SIM card includes a virtual SIM card identifier; 
     Step S 3 : determine whether the request for connecting to the virtual SIM card has been authenticated; 
     Step S 4 : if it is determined that the request for connecting to the virtual SIM card is authenticated, send a connection-request-success message to terminal device  100  to connect terminal device  100  with the virtual SIM card; 
     Step S 5 : if it is determined that the request for connecting to the virtual SIM card is not authenticated, send a connection-request-failure message to terminal device  100 . 
       FIG. 6  is a flowchart illustrating a detailed embodiment of step S 3  according to the embodiment as illustrated in  FIG. 5 . The method of  FIG. 6  includes the following steps: 
     Step S 31 : receive a request for connecting to the virtual SIM card sent from terminal device  100 ; 
     Step S 32 : generate a random code based on the received request and send the random code to the virtual SIM card; 
     Step S 33 : generate a result based on the received random code; 
     Step S 34 : send the result to server  300  to cause server  300  to compare the received result with pre-stored information and to determine whether the received result matches the pre-stored information; 
     Step S 35 : if the received result matches the pre-stored information, send a connection-request-success message to terminal device  100  to connect terminal device  100  with the virtual SIM card; 
     Step S 36 : if the received result does not match the pre-stored information, send a connection-request-failure message to terminal device  100 . 
     Referring to  FIG. 7 , the above-described process of subscribing to a virtual SIM card can be similar to an existing online shopping process. For example, a user can purchase a virtual SIM card from an online store of a virtual card vendor through a client-side terminal or a browser.  FIG. 7  provides an exemplary ordering which can be placed between steps S 1  and S 2  in  FIG. 5 , this method including the steps of: 
     Step S 11 : determine whether there is a subscription relationship between a user ID and the virtual SIM card identifier; 
     Step S 12 : if there is no subscription relationship between the user ID and the virtual SIM card identifier, send a message to terminal device  100  indicating terminal device  100  has no right to request for connecting to the virtual SIM card; 
     Step S 13 : if there is a subscription relationship between the user ID and the virtual SIM card identifier, the process proceeds to step S 2 . 
     Referring to  FIG. 8 , the method can further include steps prior to step  11  in  FIG. 7 , the steps include: 
     Step S 01 : receive the request for subscribing to the virtual SIM card, the request for subscribing to the virtual SIM card including the user ID and the virtual SIM card identifier; 
     Specifically, the above-described the virtual card server  300  can display the available virtual SIM card identifiers to a user in advance through a network for the user to select. After the user makes a selection, server  300  may generate a user instruction which is then input into terminal device  100 . Terminal device  100  subsequently may generate a request for subscribing to the virtual SIM card based on the user instruction and the user ID registered in advance by the user, and may transmit the request for subscribing to the virtual SIM card to the virtual card server  300 . 
     Step S 02 : generate an order based on the user ID and the selected virtual SIM card identifier, and send the order number of the order to the terminal device  100 , the order including the user ID and the virtual SIM card identifier; 
     Specifically, the user ID and the virtual SIM card identifier may be recorded in the order, and the current status can be additionally recorded as “unpaid”. The order number and the order may have a one-on-one correspondence. 
     Step S 03 : receive a payment result notification from a third-party payment server as a feedback to the payment request. In some embodiments, both the payment request and the payment result notification include the order number; 
     Specifically, terminal device  100 , after receiving the order number, may transmit a payment request to the third-party payment server. In some embodiments, the payment request includes the order number and the related information such as the bank account number. After executing a debit operation in accordance with the payment request, the third-party payment server may generate a payment result notification including the order number, and sends the payment result notification to the virtual card server  300 . 
     Step S 04 : determine if the payment is successful based on the payment result notification; 
     Step S 05 : when the payment is successful, obtain the user ID and the virtual SIM card identifier in the corresponding order based on the order number in the payment result notification, and subsequently establish a subscription relationship between the user ID and the virtual SIM card identifier and transmit a subscription success message; 
     Specifically, upon performing a successful payment, the virtual card server  300  may establish a corresponding subscription relationship based on the user ID and the virtual SIM card identifier in the corresponding order, and may transmit the virtual subscription success message to terminal device  100  to prompt the user to use the virtual SIM card. 
     Step S 06 : when the payment is not successful, transmit a continue-to-pay or a cancel-the-order message. 
     In some embodiments, the disclosed multi-terminal mapping system and method associated with a virtual SIM card can store one or more virtual SIM cards in the cloud so that a given virtual SIM card can be simultaneously read and mapped by multiple terminal devices, so that the multiple terminal devices mapped to the same virtual SIM card can have the same SIM card attributes to allow sharing cloud resources and to simplify processes of sharing a virtual SIM card with multiple terminals.
