At present, a smart device usually accesses the Internet via a physical Subscriber Identity Module (SIM) card or a Wireless Fidelity (WIFI) chip built in the smart device. On the one hand, for the solution of accessing the Internet via the built-in WIFI chip, because WIFI hotspots need to exist around the smart device during the accessing, there may be large limitations for outdoor mobile smart devices. On the other hand, for the solution of accessing the Internet via the built-in physical SIM card, because the built-in SIM number resources are rare, high production costs of the smart devices become problematic. Further, for a mobile smart device, since the demand for accessing the Internet is temporary, the built-in physical SIM card is a kind of resource waste.

In view of the above, the present disclosure proposes a method for accessing an operator network (e.g., a cellular network provided by a wireless service provider). A smart device uploads detected information regarding an operator network to a server end, and receives a local virtual SIM card which is sent from the server end and is corresponding to the operator network, and then accesses the operator network based on the local virtual SIM card. Thus, virtual SIM card resources can be dynamically requested from the server end without need of building a physical SIM card in the device.

FIG. 1 shows a method for accessing an operator network according to an exemplary aspect. The method for accessing an operator network is applied in a smart device and includes the following steps.

In step 101, detected information regarding an operator network is uploaded to a server end.

In step 102, a local virtual SIM card which is sent from the server end and is corresponding to the operator network is received.

In step 103, the operator network is accessed based on the local virtual SIM card.

In the above steps, the smart device may include mobile smart devices, such as mobile phones or other mobile smart devices; the server end may include distribution servers, server clusters or a cloud platform for providing virtual SIM card distribution services for smart devices. Different from the currently used physical SIM card which is removable from a mobile terminal, the virtual SIM card is a virtualization technology which simulates a virtual SIM card on a mobile terminal and uses the virtual SIM card to replace a physical SIM card to finish user identity verification and network authentication.

In the aspect, there is no built-in physical SIM card in a smart device, and when the smart device is produced, information regarding the virtual SIM card may be built in a safe storage region in the smart device. A plurality of smart devices may share the same information regarding a virtual SIM card. The information regarding a virtual SIM card may be pre-configured as only having an ability of accessing a distribution server. When the information regarding a virtual SIM card is configured as only having an ability of accessing a distribution server, the smart device may perform normal detections and access an available operator network in surroundings via the built-in information regarding the virtual SIM card, but cannot obtain corresponding network data services from the available operator network in surroundings.

Further, a function option for starting a network access service may be pre-configured in the smart device. When the smart device needs to access the Internet, a user may enable the function for accessing an operator network by switching on the function option. The function option may be realized by a physical switching button preset on the smart device, or may be a virtual functional switching option in the system of the smart device.

After the above function option is switched on, the smart device may detect operator networks in surroundings by a built-in virtual SIM card and determine whether there is an available operator network among the detected operator networks in surroundings. If there is an available operator network among the detected operator networks in surroundings, the smart device may upload the information regarding the operator network to the distribution server, for example, information such as the country or region which the available operator network belongs to.

The uploading of the information regarding the operator network by the smart device may be realized by different implementations under different application scenarios.

On the one hand, for regions which are covered only by operator networks, for example, the wild, the built-in virtual SIM card in the device has the ability of accessing the distribution server, and thus when the smart device uploads the information regarding the operator network, the smart device may upload the information regarding the operator network to the distribution server based on the built-in virtual SIM card.

In implementations, when the built-in virtual SIM card detects the available operator network, the smart device may access the operator network and may try to establish a remote connection with the distribution server via the operator network. If the remote connection is successfully established, the smart device may upload the information regarding the available operator network to the distribution server. For detailed procedure of accessing the operator network via the virtual SIM card, existing implementations may be referred to and descriptions thereof are omitted in the aspect.

Rather, if the built-in virtual SIM card detects a plurality of available operator networks, the smart device may output the plurality of available operator networks in a list form to the user to make the user select an operator network to be accessed.

On the other hand, for regions where there are free WIFI hotspots, when the smart device uploads the information regarding the operator network, the smart device may upload the information regarding the operator network to the distribution server via the WIFI hotspots.

In implantations, when the built-in virtual SIM card detects an available operator network, the smart device may detect whether there is an available WIFI hotspot in surroundings; if there is an available WIFI hotspot in surroundings, the smart device may access the WIFI network via the built-in WIFI chip and establish a remote connection with the distribution server via the WIFI network, and then upload the information regarding the available operator network to the distribution server based on the established remote connection.

In the aspect, after the distribution server receives the information regarding the operator network uploaded by the smart device, the server may send the information regarding a local virtual SIM card corresponding to the operator network to the smart device and locally save a correspondence between the smart device and the information regarding the local virtual SIM card.

For example, when a user is internationally roaming carrying a smart device, the distribution server may determine whether a cooperation with an operator is established according to the information uploaded by the smart device such as the country or the region which the operator network belongs to; if the cooperation is established, the distribution server has a right of distributing local virtual SIM cards corresponding to the operator, and may thereby directly send a local virtual SIM card corresponding to the operator to the smart device.

After receiving the local virtual SIM card sent from the distribution server, the smart device may save the information regarding the local virtual SIM card in the safe storage region in the smart device. The smart device may initiate identity verification and network authentication to the local operator network via wireless channels according to the virtual SIM card. After the authentication is passed, the smart device may access the operator network using a local user identity to enjoy the network data services provided by the operator network.

In the aspect, the information regarding the local virtual SIM card sent from the distribution server to the smart device may be recycled by the distribution server.

On the one hand, when the smart device does not need to access the operator network, the user may close the operator network access service by switching off the above function option. After the user switching off the above function option, the smart device is triggered to delete information regarding the local virtual SIM card stored in the safe storage region, and meanwhile to send to the server end a notification message for recycling the information regarding the local virtual SIM card.

On the other hand, when the built-in virtual SIM card detects that accessing the current operator network results in roaming, for example, the smart device carried by the user has moved out of the coverage of the operator network and entered into the coverage of another operator network, high charge will be incurred if the smart device still accesses the network via the received information regarding the local virtual SIM card. For such case, when the built-in virtual SIM card detects that accessing the current operator network will result in roaming, the smart device is triggered to delete the information regarding the local virtual SIM card stored in the safe storage region, and meanwhile to send to the server end a notification message for recycling the information regarding the local virtual SIM card. Rather, after roaming occurs, and the user still has the demand for accessing the operator network, the distribution server may re-send a local virtual SIM card for the smart device based on the above implementation procedure.

After the distribution server receives the notification message sent from the smart device for recycling the sent information regarding the local virtual SIM card, the distribution server may recycle the information regarding the local virtual SIM card, and delete the locally saved correspondence between the smart device and the information regarding the local virtual SIM card. Thus, the virtual SIM card may be reutilized by the distribution server, i.e., the virtual SIM card may be sent to other smart devices as virtual SIM card resources. In this way, recycling of virtual SIM card resources may be realized and thus the utilization of the virtual SIM card resources is improved.

In the above aspects, the smart device uploads the detected information regarding an operator network to a server end, receives a local virtual SIM card which is sent from the server end and is corresponding to the operator network, and then accesses the operator network based on the local virtual SIM card. Thus, virtual SIM card resources can be dynamically requested from the server end without need of building a physical SIM card in the device. Consequently, enterprise costs are effectively reduced. Meanwhile, in the above aspects, the recycling scheme of virtual SIM cards is introduced, and the distribution server may reutilize virtual SIM card resources which have already been sent, and thereby the utilization of the virtual SIM card resources is improved.

FIG. 2 shows a method for accessing an operator network according to an exemplary aspect. The method for accessing an operator network is applied in a smart device and includes the following steps.

In step 201, an available operator network is detected by a built-in virtual SIM card.

In step 202, whether a preset function option is switched on is determined.

The sequence of steps 201 and 202 may be reversed.

In step 203, when the preset function option is switched on, a remote connection with a server end is established via a virtual SIM card built in the smart device. The built-in virtual SIM card is pre-configured as only having an ability of accessing the server end.

In step 204, based on the established remote connection, the detected information regarding the operator network is uploaded to the server end.

In step 205, a local virtual SIM card which is sent from the server end and is corresponding to the operator network is received.

In step 206, the operator network is accessed based on the local virtual SIM card.

The uploading of the information regarding the operator network by the smart device may be realized by different implementations under different application scenarios.

In the aspect, the information regarding the local virtual SIM card sent from the distribution server to the smart device may be recycled by the distribution server.

On the other hand, when the built-in virtual SIM card detects that accessing the current operator network results in roaming, for example, the smart device carried by the user has moved out of the coverage of the operator network and entered into the coverage of another operator network, high charge will be incurred if the smart device still accesses the network via the received information regarding the local virtual SIM card. For such case, when the built-in virtual SIM card detects that accessing the current operator network will results in roaming, the smart device is triggered to delete the information regarding the local virtual SIM card stored in the safe storage region, and meanwhile to send to the server end a notification message for recycling the information regarding the local virtual SIM card. Rather, after roaming occurs, and the user still has the demand for accessing the operator network, the distribution server may re-send a local virtual SIM card for the smart device based on the above implementation procedure.
