DETAILED DESCRIPTION OF THE INVENTION

[0019] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be described below clearly and completely based on the drawings of the embodiments of the present invention, but it should be clear that the described embodiments are only a part of the embodiments of the present invention, and are not all of the embodiments. Any other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without any inventive work are all included in the protection scope of the present invention.

[0020] The inventors of the present application have discovered that in the prior art, when a user arrives in a country that does not support physical SIM cards, the user must manually remove the physical SIM card or manually install the cloud card as the priority, otherwise the user cannot turn on the cloud card to access the network, which causes great inconvenience to the user. The embodiments of the present invention provide the following technical solutions:

[0021] As shown in Figure 1, according to a first aspect, an embodiment of the present invention provides a method for a communication device to access a network, the method including the following steps:

[0022] When a communication device is connected to a network, it detects the mobile country code of the current network by reading the PLMN information of the current network. The PLMN parameters can be read from the systemInformationBlockType1 module of the LTE BCCH (Broadcast Control Channel). The communication device may be a device that supports both physical and cloud cards, such as a cross-border MiFi, mobile phone, CPE, or communication module.

[0023] Regarding PLMN (Public Land Mobile Network), a cellular mobile communications network operated by a certain operator in a certain mode in a certain country or region is called a PLMN. A PLMN is a network established and operated by a government or an operator authorized by the government for the purpose of providing land mobile communications services to the public. The network can interconnect and communicate with other communications networks, such as the PSTN (Public Switched Telephone Network), to form a regional or national communications network.

[0024] A PLMN number consists of MCC (Mobile Country Code) and MNC (Mobile Network Code), i.e. PLMN = MCC + MNC. For example, China Mobile's PLMN is 46000 (MCC:460, MNC:00).

[0025] The IMSI information of the physical card of the communication device is compared with the mobile country code to determine whether they are the same. IMSI generally refers to the International Mobile User Identity (IMSI). The first three digits of the IMSI of the physical card are the MCC of the country in which the carrier is located. The MCC of the country to which the carrier is traveling is detected and compared to determine whether they are the same, thereby determining whether the card is a physical card or a cloud card. For example, an IMSI of 310150123456789.310 means that the MCC of the country in which the carrier is located is the United States. Similarly, an IMSI of 460001357924680.460 means that the MCC of the country in which the carrier is located is China.

[0026] As shown in Figure 2, if it is determined that they are the same, the physical card is used to register with the network and provide mobile network services. If it is determined that they are not the same, the cloud card is used to register with the network and provide mobile network services. Mobile network services include data services, voice services, video services, e-commerce services, etc. The physical card may be a physical card such as a standard SIM card, USIM card, patch card, or eSIM card, and the cloud card may be a cloud communication virtual card such as a vSIM or cloud SIM.

[0027] eSIM, short for embedded SIM (also known as eUICC), differs from traditional removable SIM cards in that the SIM card is inserted directly into the device. Therefore, eSIM eliminates the need for a SIM card slot, enabling devices to be lighter and more reliable. By virtualizing the SIM card functions and integrating the device, users can also enjoy a new experience when switching SIM card numbers. Users no longer need to constantly insert and remove traditional SIM cards. Instead, they can communicate directly with their devices. Through apps and cloud computing, intelligent terminal devices can dynamically connect to selected local networks across the globe, ensuring that devices always enjoy superior network speeds. In this way, eSIM not only improves the overall user experience, but also greatly facilitates device management and allocation.

[0028] vSIM is a virtual SIM card technology that specifically refers to a form in which communication is fully realized through the hardware and software of the communication module itself, without the need for a physical SIM card. A communication module with vSIM functionality combines custom-built base software with the vSIM to encrypt and store data (IMSI, KI, etc.). Network registration, authentication, and communication processes are automatically processed, providing a stable communication experience even without a physical SIM card. The global SIM connection cloud service provides a vSIM-type connection service, eliminating the need for a physical card on the user's device. Instead, the user can connect to and access the network using the built-in communication module that supports vSIM technology software. It also offers more flexible functionality than a physical card, supporting and selecting the data volume of the global mobile network provided by the global SIM connection service. The global SIM connection service allocates number resources based on the IMEI and connection service plan of the module provided by the user. Users simply turn on the module device, which automatically downloads the corresponding number from the global SIM connection service and starts the network connection function.

[0029] For example, in the case of international roaming, if the first three digits of the IMSI code are 460 and the detected mobile country code of the current environment network is also 460, it means that the physical card currently used by the communication device is located within the border of China, the country to which it belongs, and the physical card is used first to register with the network and provide mobile network services.

[0030] When the communication device leaves the current environment network, it compares the IMSI information of the physical card of the communication device with the mobile country code of the next environment network to determine whether they are the same, and if it determines that they are not the same, it closes the physical card and registers with the network using the cloud card.

[0031] For example, in the case of international roaming, if the first three digits of the IMSI code are 460 and the mobile country code detected upon moving to the next network environment is 310, it is determined that the communication device has moved to the United States and that the physical card currently used by the communication device is not located within the borders of China, the country to which it belongs. The physical card is closed using a program installed in the communication device system itself. For example, the Android system generally includes a program for closing the physical card. Next, the cloud card is used to register with the network and provide mobile network services. If the communication device moves again within the borders of China, the physical card is first turned on and registered with the network to provide mobile network services. Repeating this process, depending on the network environment, allows the user to select either the physical card or the cloud card to register with the network, thereby providing a better user experience.

[0032] As shown in Fig. 3, according to a second aspect, an embodiment of the present invention further provides a system for a communication device to access a network, including a detection module, a comparison module, and an analysis execution module. The detection module is for detecting a mobile country code of a current environment network when the communication device is staying in the network, the comparison module is for comparing the IMSI information of a physical card of the communication device with the mobile country code to determine whether they are the same, and the analysis execution module analyzes the comparison result and, if it determines that they are not the same, registers the network using the cloud card.

[0033] The detection module includes a PLMN information reading module for reading the PLMN information of the current environment network and identifying the mobile country code of the current environment network. The comparison module includes an IMSI information reading module for reading the first three digits of the IMSI information and comparing it with the mobile country code. The analysis execution module includes a mobile analysis execution module. When the communication device leaves the current environment network, the mobile analysis execution module compares the IMSI information of the physical card of the communication device with the mobile country code of the next environment network to determine whether they are the same. If they are not the same, the physical card is closed and the cloud card is used to register with the network.
