[0040] The concept, specific structure and technical effects of the present application will be further described below in combination with the drawings, so as to fully understand the purpose, features and effects of the present application.

[0041] FIG. 1 is a schematic flowchart of a cloud card replacement method according to one embodiment.

[0042] FIG. 2 is a flowchart of cloud card replacement according to one embodiment.

[0043] FIG. 3 is a schematic block diagram of an electronic device according to one embodiment. DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0045] It should be noted that, in this document, relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any such actual relationship or order between such entities or actions.

[0046] The inventors of the present application find that in the related art, the general cloud card is allocated as a local virtual card in the current country, that is, the current country's operator card. If the device crosses the border, the current country's operator card generally cannot register the roaming network. The device needs to spend a long time to identify the cross-border card replacement, which can cause the user to be unable to use the network for a long time, and the operation experience is poor.

[0047] In the related art, in the technical solution of using a cloud card for online in a device, the general cloud card is allocated as a local virtual card in the current country, that is, the current country's operator card. If the device crosses the border, the current country's operator card generally cannot register the roaming network. The device needs to spend a long time to identify the cross-border card replacement, which can cause the user to be unable to use the network for a long time.

[0048] In the cloud card solution in the related art, the cloud card allocated to the device is generally a local virtual card in the current country. Compared with a roaming card, the local virtual card in the current country is cheaper, and the network priority is higher, and the rate and experience are better. However, if the device carrying the local virtual card in the current country crosses the border, the local virtual card in the current country can not register the roaming network, or can only try to register the roaming network because of the priority of the local network, unless the local network cannot be registered. Therefore, it takes a long time to register the roaming network during the cross-border process. In the related art, in order to control the cost, the roaming switch in the device is also turned off. Even if the roaming network is used during the cross-border process, the device cannot be connected to the network. Therefore, there is no method for quickly identifying the cross-border and accurately replacing the cloud card, and the cross-border experience is poor.

[0049] In the related art, when the device with the local virtual card in the current country crosses the border, the following method is generally used to replace the cloud card:

[0050] (1) A registration timeout timer is set. If the local virtual card in the current country is disconnected after crossing the border, the device needs to listen for 3 minutes or more. If the device cannot register the network within the timeout time, the device triggers the cloud card replacement. This method of replacing the cloud card can make the device wait for 3 minutes or more, which is time-consuming and can cause poor user experience.

[0051] (2) Modify the bottom layer modem (modem). During the cross-border process, the bottom layer obtains and reports the cross-border network, and then the upper layer business performs relevant strategies and algorithms to identify that the cross-border network is available, and then replaces the cloud card. However, this method has the following disadvantages: the bottom layer modem code needs to be modified, different products and different chips can need to be re-adapted and modified, which is troublesome, and even if the cross-border network is obtained, a complex algorithm is still needed to ensure stable replacement.

[0052] In summary, the cloud card replacement solution in the related art cannot provide a convenient and fast user experience.

[0053] In view of this, the application provides a cloud card replacement method, an electronic device and a computer readable storage medium, which can quickly identify cross-border and, when a cross-border network is found to be available for registration, quickly find a new cloud card matching the region where the device is currently located by identifying a mobile network country code (MCC), replace the cloud card in the device, and achieve fast replacement to a local virtual card in a cross-border country, thereby effectively optimizing user experience of cloud card replacement.

[0054] The above technical solutions will be described in detail below with reference to specific embodiments.

[0055] FIG. 1 is a schematic flowchart of a cloud card replacement method according to an embodiment.

[0056] The cloud card replacement method of the embodiments of the application is applied to an electronic device, which includes a seed card capable of global roaming, and in this embodiment, a global roaming virtual card can be used to constitute the seed card.

[0057] The method includes:

[0058] Step 101: In the initial state of the electronic device, the seed card is connected to a cloud card server.

[0059] Step 102: A cloud card corresponding to the country or region where the electronic device is located is allocated to the electronic device based on the first mobile network country code.

[0060] Step 103: The cloud card is registered in a network through the network of the seed card.

[0061] Step 104: The first mobile network country code is identified, wherein the first mobile network country code is a mobile network country code in the network identification during the connection of the seed card to the cloud card server.

[0062] Step 105: It is determined whether the identified first mobile network country code matches the second mobile network country code, wherein the second mobile network country code is a mobile network country code corresponding to the original cloud card used by the electronic device.

[0063] The specific step of determining whether the identified first mobile network country code matches the second mobile network country code is to determine in real time by the electronic device whether the identified first mobile network country code matches the second mobile network country code.

[0064] Step 106: When the first mobile network country code matches the second mobile network country code, the original cloud card in the electronic device is not replaced.

[0065] Step 107: When the first mobile network country code does not match the second mobile network country code, the original cloud card used by the electronic device is closed, a new cloud card corresponding to the country or region according to the first mobile network country code is allocated to the electronic device, and network registration of the new cloud card is performed through the network of the seed card.

[0066] By the cloud card replacement method in this embodiment, whether the cross-border is determined by comparing the mobile network country code in the network identification in the process of connecting the seed card and the cloud card server with the mobile network country code corresponding to the original cloud card used by the electronic device. When the mobile network country code in the network identification in the process of connecting the seed card and the cloud card server does not match the mobile network country code corresponding to the original cloud card used by the electronic device, the original cloud card used by the electronic device is closed, and a new cloud card matching the mobile network country code in the network identification in the process of connecting the seed card and the cloud card server is allocated to the electronic device by the cloud card server, so as to ensure the quick replacement of the cloud card in the electronic device and effectively improve the cross-border recognition efficiency of the device and effectively optimize the user experience.

[0067] When the electronic device obtains the mobile network country code corresponding to the cloud card used by the electronic device (i.e. the second mobile network country code), the mobile network country code corresponding to the cloud card currently used by the electronic device can be stored in the electronic device, so that the first mobile network country code recognized in real time can be compared with the second mobile network country code pre-stored in the electronic device. When the electronic device replaces the cloud card used by the electronic device, the mobile network country code corresponding to the original cloud card can be deleted from the electronic device, and the mobile network country code corresponding to the new cloud card can be stored in the electronic device, so as to provide preparation for comparison between the mobile network country codes. This operation mode can reduce the step of repeatedly identifying the second mobile network country code by the electronic device, simplify the identification process, and further improve the cloud card replacement efficiency.

[0068] The process of identifying the first mobile network country code provided by the embodiment of the present application is described in detail as follows:

[0069] The cloud card server obtains the network identification in the process of connecting the seed card and the cloud card server.

[0070] The mobile network country code in the network identification is identified to identify the first mobile network country code.

[0071] The process of performing network registration of the new cloud card through the network of the seed card provided by the embodiment of the present application is described in detail as follows:

[0072] sending a network registration request of a new cloud card through the network of the seed card, and when receiving the network registration request of the new cloud card, obtaining an authentication request information sent by the network of the seed card;

[0073] sending the authentication request information to the cloud card server for authentication by using the data service of the seed card, and obtaining an authentication result after the authentication of the cloud card server;

[0074] sending the authentication result to the network of the seed card, and when the authentication result is consistent with an expected result in the network of the seed card, the authentication is successful, so that the network of the seed card accepts the network registration request of the new cloud card;

[0075] when the network of the seed card accepts the network registration request of the new cloud card, the network registration of the new cloud card is successful.

[0076] In order to enable those skilled in the art to better understand the present application, the present application will be further described below in conjunction with an embodiment:

[0077] In this embodiment, the seed card capable of global roaming is composed of a global roaming seed card, and the global roaming seed card is arranged in an electronic device. When the electronic device is running, an additional replaceable cloud card needs to be registered.

[0078] When the electronic device is running, the global roaming seed card is used to connect with the cloud card server, the cloud card server determines the country where the electronic device is currently located according to the network registered by the global roaming seed card, and then allocates a local virtual card (i.e. a cloud card) of the country to the device, and then downloads the cloud card and transmits and receives the cloud card authentication through the network of the global roaming seed card, after the cloud card registration network and dialing ok, the electronic device can normally access the network, and the cloud card network is used for data use. When the electronic device is running, both the two cards (i.e. the global roaming seed card and the cloud card) need to be online in real time, and can normally register the network.

[0079] During the cross-border process of the electronic device, since the global roaming seed card can roam the networks of different countries, when the electronic device moves from a country a to a country b, the roaming network of the country a does not meet the registration, while the network of the country b meets the registration, the roaming virtual card will register the roaming network of the country b, and then successfully replace and register to the network of the country b.

[0080] If the country code of the network registered by the global roaming seed card is changed during the operation of the device, it is immediately determined that the device is crossing the border, at which time the original cloud card is immediately closed, the global roaming seed card is connected to the server to apply for a replacement cloud card, and the local virtual card of the country after crossing the border is replaced. In this way, the feature of the global roaming seed card that can be replaced in the roaming country network during the crossing of the border is utilized to timely replace the cloud card after the country network is replaced, and the global roaming seed card is successfully registered and can download the cloud card, ensuring that the replacement cloud card can also be stably registered in the current country network.

[0081] The replacement process of the cloud card between two countries or regions will be further described below in combination with FIG. 2, which is a flowchart of the replacement of the cloud card according to an embodiment.

[0082] If the user carries the electronic device including the global roaming seed card to move between countries a and b, the relevant operation process is as follows:

[0083] Before crossing the border, the electronic device is in the country a, and the local virtual card of the country a is registered in the country a network. In this process, when the country a network meets the registration, the electronic device is registered in the country a network through the internal global roaming seed card roaming. The cloud card in the device is the local virtual card of the country a.

[0084] When the user carries the electronic device to move from the country a to the country b, the country a network does not meet the registration of the device network, and the country b network meets the registration of the device network. The global roaming seed card in the device is replaced from the country a network to the country b network. In this process, the local virtual card of the country a in the device is dropped and cannot be registered.

[0085] When the electronic device is in the country b, the local virtual card of the country a is dropped. At this time, since the global roaming seed card is successfully registered in the country b network, the country code is changed. In this process, the server can be immediately connected to apply for a replacement of the local virtual card of the country b.

[0086] After crossing the border, when the user is in the country b, the electronic device successfully replaces the local virtual card of the country b and is successfully registered, and can access the network.

[0087] In this scheme, the global roaming virtual card + cloud card is mainly used to realize the network access of the electronic device. In the scheme, the feature that the global roaming virtual card can be replaced across the border (that is, the seed card that can globally roam is replaced from the first country PLMN (that is, the public land mobile communication network) to the second country PLMN, and the registered PLMN can obtain the current country code (that is, the mobile network country code)) is utilized to confirm that the country has been replaced, quickly notify the cloud card to replace the card with a different MCC (that is, the mobile network country code), and replace the cloud card in this way to achieve a more accurate and reliable effect.

[0088] In a second aspect, the present application provides an electronic device, the structure of which is shown in Figure 3, which is a schematic block diagram of an electronic device according to an embodiment.
