In this embodiment, the cloud server obtains at least one piece of SIM card information, where at least one SIM card corresponding to the at least one piece of SIM card information belongs to the same user; that is, the user obtains at least one SIM card (the at least one SIM card may be a physical SIM card or a virtual SIM card) through the operator business office or through the online application office, and the user communicates through the SIM card. Specifically, the obtaining, by the cloud server, at least one SIM card information includes: the cloud server outputs a login interface to the mobile terminal; the cloud service account and the password meeting the login conditions are obtained, and the cloud service account login process is completed; obtaining at least one SIM card information sent by the mobile terminal (the at least one SIM card information can be obtained through user input); the cloud server is communicated with network side equipment of a service provider corresponding to the at least one SIM card information, and whether the at least one SIM card information meets a condition is determined; whether the at least one SIM card information satisfies a condition such as: whether SIM card information is a real-name application, namely whether the SIM card information is related to the identity card information of a user, whether the SIM card information is in arrearage and stop (namely halt) states and the like, and when the SIM card information is the real-name application and the SIM card information is not in the arrearage and stop (namely halt) states, determining the at least one SIM card information; storing the at least one SIM card information in a virtual SIM card respectively; each cloud service account corresponds to at least one virtual SIM card, and each virtual SIM card is associated with one SIM card information. The network side device of the service provider may specifically be a Customer Relationship Management (CRM) system of an operator; specifically, how the CRM of the operator determines whether the SIM card information satisfies the preset condition may refer to the prior art, which is not described herein again.

In the embodiment of the present invention, the service provider is specifically an operator, and the operator is, for example, mobile, connected, or the like; the network side device of the service provider is specifically a network side device of an operator, which is the same as below and is not described in detail again.

As another embodiment, when the mobile terminal does not have the associated cloud service account, the cloud server outputs a registration interface to the mobile terminal, and the user may complete registration based on the guidance information of the registration interface to obtain the cloud service account associated with the mobile terminal.

In step 102, specifically, the cloud server communicates with the network side device of the service provider corresponding to the at least one piece of virtual SIM card information, and completes a card writing operation based on the at least one piece of virtual SIM card information, including:

and writing the card writing data of the at least one virtual SIM card into the corresponding virtual SIM card through the network side equipment of the service provider.

Fig. 2 is a schematic view of a card writing operation flow in the communication method according to the embodiment of the present invention, in this schematic view, taking network devices of three service providers (i.e., operators) corresponding to virtual SIM card information in the cloud server as examples, the network devices are an operator device a, an operator device B, and an operator device C respectively; as shown in fig. 2, the card writing operation method includes:

step 1021, the cloud server sends card writing requests to the operator equipment A, the operator equipment B and the operator equipment C respectively; the card writing request carries virtual SIM card information; carrying virtual SIM card information matched with the operator network for card writing requests sent to different operator devices; the first virtual SIM card corresponds to the operator equipment A, the cloud server sends a first card writing request to the operator equipment A, and the first card writing request carries the first virtual SIM card information, and so on.

Step 1022, the CRM system of the corresponding operator device applies for real-time card writing data according to the virtual SIM card information in the received card writing request, performs message assembly through the on-site card writing system, and sends the card writing data to the cloud server.

And 1023, the cloud server obtains card writing data sent by the operator equipment, and writes the card writing data into the corresponding area of the virtual SIM card.

Specifically, the card writing operation process of the cloud server is a card writing operation process of the simulated mobile terminal, and a specific implementation process is the same as the card writing process of the mobile terminal, except that in this embodiment, the cloud server simulates a card writing operation on each virtual SIM card to the network side device of the corresponding service provider, and the specific operation process may refer to the card writing process of the mobile terminal in the prior art, which is not described in detail in this embodiment.

In step 103, specifically, before the cloud server completes the authentication operation based on the at least one virtual SIM card information, the method further includes:

and respectively communicating with the network side equipment of the service provider corresponding to the at least one piece of virtual SIM card information to carry out authentication operation on the at least one piece of virtual SIM card information, and sending the attribute information of the mobile terminal to the network side equipment of the corresponding service provider, so that the corresponding virtual SIM card information of the network side equipment of the service provider is associated with the attribute information of the terminal and is registered in the network side equipment of the service provider.

Specifically, a user logs in a cloud service account at a mobile terminal when using the mobile terminal for the first time; before the authentication operation of the at least one piece of virtual SIM card information is carried out, the mobile terminal prefers one network in a hybrid network to carry out network connection, and based on the network connection, the cloud server outputs a login interface to the mobile terminal; and the mobile terminal inputs a cloud service account and a password on the login interface to log in. That is, before the authentication operation of the at least one piece of virtual SIM card information is completed, the mobile terminal can only use a data network of a certain operator to perform the verification operation and the subsequent configuration operation of the cloud service account. Further, after the cloud service account is successfully logged in, the cloud server outputs a configuration interface to the mobile terminal; the configuration interface comprises at least one SIM card information (such as a mobile phone number) under the cloud service account and corresponding operator information, a user can select the SIM cards which are simultaneously opened in the configuration interface, the SIM cards which are simultaneously opened and characterized to be online at the same time can simultaneously carry out network communication, and for example, when voice communication (namely calling) is carried out through one SIM card, short messages can be received/sent through the other SIM card. As one embodiment, in the configuration interface, if a user wishes to newly open a number in a certain operator, a number selection function is provided for the user to select; after the selection is completed, executing a new account opening card writing process, wherein the specific new account opening card writing process can refer to a new account opening card writing process in the prior art, and is not described herein again; and when the card writing is successful, the newly opened number can be selected by the user. Further, after the user finishes the selection, the cloud server obtains a number selection result sent by the mobile terminal, and determines at least one piece of virtual SIM card information to be subjected to authentication operation based on the number selection result. Further, the cloud server communicates with the network side devices of the service provider (i.e., the operator) corresponding to the at least one piece of virtual SIM card information one by one, and it can be understood that, in this embodiment, according to a method for authenticating the network side devices of the service provider (i.e., the operator) by the mobile terminal for the SIM information, the cloud server simulates the mobile terminal to authenticate the virtual SIM card information to the network side devices of the service provider (i.e., the operator), and the authentication process may refer to an SIM card authentication process of the mobile terminal in the prior art, which is not described in detail in this embodiment. In this embodiment, the cloud server also obtains attribute information of the mobile terminal, and sends the attribute information of the mobile terminal to the network side device of the corresponding service provider; the attribute information includes an identifier and an address of the Mobile terminal, where the identifier of the Mobile terminal may specifically be an International Mobile Equipment Identifier (IMEI), and the address of the Mobile terminal may be a Media Access Control (MAC) address.

In this embodiment, the network side device of the service provider (i.e. the operator) sets a Register (IMR, IMEI and MAC Register) for associating the IMEI and MAC addresses of the mobile terminal and corresponding virtual SIM card information; when the authentication of the at least one piece of virtual SIM card information is successful, the register binds and stores the IMEI, the MAC address and the virtual SIM card information of the mobile terminal, registers an equipment number in network equipment of a corresponding service provider, opens the use authority of the equipment corresponding to the equipment number, and completes the registration operation on the network equipment of the service provider, so that the mobile terminal can communicate through the authenticated at least one virtual SIM card. Further, after the authentication is completed, the network side device of the service provider sends an authentication success message to the cloud server, and the cloud server outputs an authentication result to the mobile terminal, so that the user can know which numbers are successfully authenticated and can be used.

In this embodiment, no matter which number is selected by the mobile terminal for communication, the cloud server simulates that other numbers are in a hold state, that is, the cloud server simulates that other numbers are in a power-on online state, so as to avoid missing a call or a short message passing through other numbers.

As an embodiment, a status maintenance message is transmitted between the cloud server and the mobile terminal, so that the cloud server can monitor the status of the mobile terminal in real time.

By adopting the technical scheme of the embodiment of the invention, the cloud server stores at least one SIM card information and simulates the card opening and authentication operation of the SIM card, so that the mobile terminal always obtains the communication service authorization; the mobile terminal can select the network with the optimal signal intensity to communicate according to the network signal intensity of the current position, so that the requirement of network switching of multiple systems of multiple operators can be met, the simultaneous online of multiple numbers is realized, and the user experience is greatly improved.

Example two

Fig. 3 is a second flowchart of a communication method according to an embodiment of the present invention; as shown in fig. 3, under the description based on step 101 to step 104 in the first embodiment, further, the communication method according to the embodiment of the present invention further includes:

step 105: the cloud server receives an exit request of the mobile terminal; the quitting request comprises at least one piece of virtual SIM card information and attribute information of the mobile terminal; the attribute information of the mobile terminal includes an identifier and an address of the mobile terminal.

Step 107: and the cloud server receives a logout result sent by the network side equipment of the service provider corresponding to the at least one virtual SIM card information.

In this embodiment, the logout request may also be understood as a logout request, which is equivalent to a logout request issued to the network side device of the service provider (i.e. the operator) when the mobile terminal is powered off. In this embodiment, the mobile terminal may select a number to be logged out (or logged out) from a configuration interface provided by the cloud server, that is, in this embodiment, the mobile terminal may select at least one of the associated at least one SIM card information to perform a logging out (or logging out) operation. Further, after receiving a quit request of the mobile terminal, the cloud server obtains at least one piece of virtual SIM card information and attribute information of the mobile terminal, which are included in the quit request; the at least one piece of virtual SIM card information included in the exit request may specifically be a phone number. In another embodiment, when the mobile terminal receives a shutdown instruction, the mobile terminal actively sends a logout request to the cloud server, where the logout request includes information of all authenticated virtual SIM cards, that is, indicates that all authenticated telephone numbers are logged out.

Further, after receiving the exit request of the mobile terminal, the cloud server sends a logout request of the corresponding virtual SIM card information to the network side device of the service provider corresponding to the at least one virtual SIM card information. Specifically, the cloud server simulates a shutdown action of the mobile terminal, and requests a logout action of a corresponding virtual SIM card to the network side device of the corresponding service provider (i.e., operator). The network side device of the service provider (i.e., the operator) correspondingly performs a logout operation of the corresponding number, the network side device of the service provider (i.e., the operator) deletes the binding relationship between the device number of the mobile terminal and the mobile phone number, that is, the authentication of the device number of the mobile terminal fails, and a specific logout process may refer to a shutdown logout procedure of the mobile terminal, which is not described in detail in this embodiment. Further, after the logout is completed, the cloud server receives a logout result sent by the network side device of the service provider (i.e., the operator). And when the mobile terminal is not in a power-off state currently, the cloud server outputs the logout result to the mobile terminal.

By adopting the technical scheme of the embodiment of the invention, on one hand, the mobile terminal is always authorized by communication service by storing at least one SIM card information in the cloud server and simulating the card opening and authentication operation of the SIM card by the cloud server; the mobile terminal can select a network with the optimal signal intensity to communicate according to the network signal intensity of the current position, so that the requirement of switching multiple systems of networks of multiple operators can be met, and the simultaneous online of multiple numbers is realized; on the other hand, when the number is logged off, the logging off operation of any number can be realized through the interface where the cloud service account is located without shutdown operation, convenience is provided for a user, and the user experience is greatly improved.

step 108: when the cloud server detects that a cloud service account corresponding to the mobile terminal logs in another mobile terminal and the another mobile terminal indicates that third virtual SIM card information associated with the cloud service account is to be used for communication, the cloud server sends a device update request to network side equipment of a service provider corresponding to the third virtual SIM card information.

Step 109: after the network side equipment of the service provider corresponding to the third virtual SIM card information deletes the association relationship between the third virtual SIM card information and the attribute information of the mobile terminal and establishes the association relationship between the third virtual SIM card information and the attribute information of the another mobile terminal, the cloud server receives an authentication success message sent by the network side equipment of the service provider corresponding to the third virtual SIM card information; and the authentication success message represents that the other mobile terminal obtains the communication service authorization of the service provider corresponding to the third virtual SIM card information.

The communication method of the embodiment can be applied to the following scenes: a user logs in a cloud service account through a mobile terminal and selects a mobile phone number to be used; the cloud server detects that the cloud server account number is successfully logged in another mobile terminal and the network connection is normal, and in order to ensure that one cloud service account number can only be used by one mobile terminal, the cloud server sends a device updating request to network side equipment of a service provider (namely an operator); after receiving the device update request, the network side device of the service provider (i.e. the operator) deletes the association relationship of the previous device number (i.e. the IMEI) in the register (IMR), binds the association relationship of the new device number (i.e. the IMEI), the MAC address and the third virtual SIM card information, suspends the usage right of the device corresponding to the device number, and completes the registration operation on the network device of the service provider. That is to say, after another mobile terminal is used to log in a cloud service account, the cloud server does not need to initiate an authentication request operation again, but sends the attribute information of the another mobile terminal to the network device of the service provider for device updating, and after the updating is completed, the another mobile terminal can communicate through the number in the cloud service account.

Further, the network device of the service provider sends an authentication success message to the cloud server, and the cloud server outputs the authentication success message to the mobile terminal (a new mobile terminal logged in later) through a display interface; and simultaneously, the cloud server indicates the off-line of the cloud service account logged in by the original mobile terminal.

In this embodiment, one cloud service account may only be logged in on one mobile terminal, that is, at least one phone number integrated in the cloud service account may only be used on one mobile terminal. Therefore, potential safety hazards caused by SIM card copying in the prior art are avoided, and the network communication safety of the user is greatly improved.

By adopting the technical scheme of the embodiment of the invention, on one hand, the mobile terminal is always authorized by communication service by storing at least one SIM card information in the cloud server and simulating the card opening and authentication operation of the SIM card by the cloud server; the mobile terminal can select a network with the optimal signal intensity to communicate according to the network signal intensity of the current position, so that the requirement of switching multiple systems of networks of multiple operators can be met, and the simultaneous online of multiple numbers is realized; on the other hand, one cloud service account can only be logged in on one mobile terminal, that is, at least one phone number integrated in the cloud service account can only be used on one mobile terminal. Based on this, the potential safety hazard that SIM card duplication caused among the prior art has been avoided, user's network communication safety has been promoted greatly, user's experience has been promoted greatly.

After the at least one piece of virtual SIM card information is logged off at the network side device of the corresponding service provider, the mobile terminal cannot use the at least one piece of virtual SIM card information for communication, that is, the mobile terminal cannot use any number in the cloud service account for communication.

As another embodiment, when the mobile terminal is in an abnormal state, for example, lost, the user may log in the cloud server through another mobile terminal, and after the login is completed, the login function under the cloud service account is used to log out all the virtual SIM card information under the cloud service account, which is equivalent to a loss report operation. The cloud server sends a logout request to the network side device of the service provider corresponding to the at least one piece of virtual SIM card information, and the network side device of the service provider corresponding to the at least one piece of virtual SIM card information deletes the binding relationship corresponding to the device number of the mobile terminal, that is, the mobile terminal cannot enjoy the communication service of any number under the cloud service account number when being used. For the specific logout function, reference may be made to the abnormal machine login process in the fifth embodiment, which is not described herein again.

As another implementation manner, in this embodiment, the login interface output by the cloud server includes multiple protection mechanisms, such as password problem setting, identity real-name authentication, and the like, so as to ensure the security of the cloud service account and improve the security.
