[0002] In existing technologies, when mobile phones use integrated SIM cards (SIM cards, Subscriber Identity Modules) from different operators (such as Operator A, Operator B, and Operator C), users typically need to manually download software corresponding to the SIM card to switch network connections. This method is not only cumbersome but also provides a poor user experience. Every time a user needs to switch to another operator's network, they must do so manually, which undoubtedly increases the user's cost and time.

[0003] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The first aspect of this application provides a smart switching method for an integrated card. This method is applied to the control of an integrated card that integrates a primary data SIM card and a secondary data SIM card. The primary data SIM card includes an application layer and a card operation layer connected to each other, with the application layer connected to the secondary data SIM card. The smart switching method includes: when the integrated card is installed on a terminal device, and the primary data SIM card receives a user's card-switching command for the terminal device, the primary data SIM card controls the corresponding primary or secondary data SIM card to communicate with the terminal device according to the card-switching command; when the integrated card is installed on the terminal device, the primary data SIM card obtains the network connection status detected by the terminal device according to a preset automatic switching command, and controls the corresponding primary or secondary data SIM card to communicate with the terminal device according to the network connection status.

The method further includes: if both the primary and secondary data SIM cards cannot access the network when connected to the terminal device, the primary data SIM card establishes a connection between itself and the terminal device.

[0009] Optionally, in one embodiment of this application, the network connection status includes signal strength, network service, and network standard; the operator's main data SIM card obtains the network connection status detected by the terminal device according to a preset automatic switching instruction, specifically: when the operator's main data SIM card does not receive the switching instruction and the terminal device moves from a first position to a second position, the operator's main data SIM card obtains the signal strength, network service, and network standard of the terminal device at the second position according to the preset automatic switching instruction; or when the operator's main data SIM card does not receive the switching instruction, the operator's main data SIM card obtains the signal strength, network service, and network standard of the terminal device at preset intervals according to the preset automatic switching instruction.

[0027] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this application and not all possible implementations. Based on the embodiments in this application, those skilled in the art can obtain other embodiments without creative effort, and these embodiments are also within the protection scope of this application.

[0028] In related technologies, users need to manually download and install software corresponding to the SIM card in order to switch network connections. Manually switching networks is not only time-consuming but also prone to errors, causing unnecessary trouble for users during use. Users may need to install multiple software programs to manage different SIM cards, which not only takes up the phone's storage space but may also affect the phone's operating efficiency.

[0029] First, let's introduce the terms used in the embodiments of this application:

[0030] Network standard refers to the communication standard and technical specifications adopted by a mobile communication system. Common network standards include 2G, 3G, 4G, and the more advanced 5G. In terms of network standards, higher-level network standards (such as 4G) provide faster data transmission rates, lower latency, and better network coverage than lower-level network standards (such as 2G and 3G).

[0031] The card operating layer (used to implement the original phone card functions), also known as the COS (Card Operating System), is the operating system software residing within the SIM card. In the SIM card, the COS layer primarily implements the basic functions of the phone card, such as identity authentication, authentication operations, and storage of user information. These functions enable the operator's primary data SIM card to function as a medium for telephone communication and interact with the mobile network.

[0032] The application layer (used to implement control functions) refers to the various applications and services developed on top of the COS layer. These applications and services interact with the hardware within the card through the interfaces and protocols provided by the COS layer to implement various control functions. The functionality of the application layer is achieved by developing corresponding applications and services on the COS layer. These applications and services can be customized and extended according to user needs to meet different application scenarios and requirements.

[0033] Next, the integrated card of the embodiment of this application will be introduced.

[0034] In one embodiment of this application, as Figure 1 As shown, the integrated card, which integrates multiple carrier data cards, includes a primary carrier data card and secondary carrier data cards. The primary carrier data card includes an application layer (MCU) and a card operation layer (COS) connected to each other. The application layer is connected to the secondary carrier data cards. The primary or secondary carrier data cards communicate with the terminal device through the application layer of the primary carrier data card.

[0035] Specifically, the application layer controls the data SIM card (either the primary or secondary card) connected to it, enabling a carrier's data SIM card to communicate with the terminal device and achieve internet access.

[0036] Understandably, terminal devices (such as mobile phones, routers, and in-vehicle communication devices) have multiple built-in SIM cards, each corresponding to a network of a different operator. These SIM cards communicate with the device through the hardware and software interfaces of the terminal device. When the terminal device needs to switch network connections, the integrated card will select the optimal SIM card from among the multiple SIM cards to connect to according to preset card switching logic and conditions. This process involves operations such as disconnecting the current connection and re-establishing a new connection.

[0037] It's worth noting that the principle behind a carrier's data SIM card's ability to perform phone card and control functions is based on the following aspects: Hardware support: The carrier's data SIM card contains hardware components such as a processor and memory, which provide the necessary computing power and storage space for the operation of the COS layer and application layer; Software architecture: The COS layer and application layer constitute the software architecture of the carrier's data SIM card. The COS layer is responsible for handling the underlying protocols and data streams related to telephone communication, while the application layer is responsible for handling the applications and data related to the phone card's control functions; Interfaces and protocols: The COS layer and application layer interact through specific interfaces and protocols. These interfaces and protocols ensure data transmission and command execution between different layers, thereby enabling the phone card and control functions to work together; Network communication: The carrier's data SIM card communicates with base stations through the mobile network to achieve functions such as making calls, sending SMS messages, and data transmission. At the same time, the applications and services of the application layer can also interact with the outside world through the mobile network to achieve functions such as remote control and data synchronization.

[0038] In one embodiment of this application, in the initial state, the operator's main data SIM card communicates with the terminal device through the application layer.

[0039] Specifically, the primary data SIM card is a SIM card from operator A, and the secondary data SIM card is a SIM card from operator B.

[0040] Further, see Figure 2 The structure of the operator's main data SIM card has a first pin and a second pin. The first pin is used for data transmission between the operator's main data SIM card and the terminal device; the second pin is connected to the operator's secondary data SIM card and is also used for data transmission between the operator's secondary data SIM card and the terminal device.

[0041] In another embodiment of this application, see Figure 1 The operator's data transfer card includes a first data transfer card and a second data transfer card.

[0042] Specifically, the data transfer is handled by two SIM cards: a primary data card, a first data card, and a second data card, corresponding to SIM cards from operators A, B, and C, respectively. In this embodiment, the SIM card from operator A (i.e., the primary data card) is the default card, but other settings can be configured according to actual needs.

[0043] Further, see Figure 3The main data SIM card of an operator has a first pin, a second pin, and a third pin. The first pin is used for data transmission between the main data SIM card and the terminal device; the second pin is connected to the first data SIM card and is used for data transmission between the first data SIM card and the terminal device; the third pin is connected to the second data SIM card and is used for data transmission between the second data SIM card and the terminal device.

[0044] It should be noted that the pin configuration and structure in a SIM card are typically determined by the card's physical form and packaging. A standard SIM card usually has eight pins, but not all of them are used. These pins include critical contacts such as power (Vcc), reset (RST), clock (CLK), ground (GND), and data input / output (I / O), as well as any reserved pins (RFU). This embodiment of the application achieves the purpose of data SIM card switching by using the reserved pins of the original SIM card for communication connection with the terminal device via the aforementioned second and third pins.

[0045] In this application, by integrating the software into the application layer of the operator's main data SIM card, the integrated card can be used immediately without the need for the phone to download and switch software.

[0046] The following description, with reference to the accompanying drawings, outlines an intelligent switching method, system, integrated card, and storage medium for integrated cards according to embodiments of this application. Addressing the problem in the aforementioned related technologies where users need to manually download and install software corresponding to the SIM card to switch network connections, resulting in cumbersome switching operations, this application provides an intelligent switching method for integrated cards. This method achieves seamless switching between multiple SIM cards (i.e., integrated cards) through platform instruction switching and the detection and judgment of automatic card-switching conditions, reducing user operations and thereby improving network switching efficiency, resource utilization, and user experience. Thus, it solves the technical problem in the related technologies where users need to manually download and install software corresponding to the SIM card to switch network connections, leading to cumbersome switching operations.

[0047] It should be noted that when a terminal device has a built-in multi-network SIM card and is placed in a fixed location or moved to a certain geographical location, it will automatically switch the operator network according to the local mobile network coverage, or the platform will issue an instruction to switch the operator network.

[0048] In this application, users can seamlessly switch between integrated cards without manually switching networks, greatly improving the user experience; integrated card management is achieved through master control slicing, eliminating the need to install multiple software programs and saving mobile phone storage space and operating resources; intelligent switching based on signal strength, network service status, and network standard effectively improves network stability and reliability; automatic network switching reduces manual operation by users, improving work efficiency and productivity.

[0049] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0050] The intelligent switching method for integrated cards described in the preferred embodiments of this application, such as... Figure 4 As shown, the intelligent switching method for the integrated card includes the following steps:

[0051] In step S101, when the integrated card is installed on the terminal device, and the operator's main data card receives a card-switching instruction from the user for the terminal device, the operator's main data card controls the corresponding operator's main data card or operator's secondary data card to communicate with the terminal device according to the card-switching instruction.

[0052] In one possible implementation, the primary data SIM card of the operator is initially connected to the terminal device. When the primary data SIM card is connected to the terminal device through the application layer, the primary data SIM card disconnects from the terminal device according to the card-switching instruction and establishes a connection between the secondary data SIM card and the terminal device. When the secondary data SIM card is connected to the terminal device through the application layer, the primary data SIM card disconnects from the terminal device according to the card-switching instruction and establishes a connection between the primary data SIM card and the terminal device.

[0053] Specifically, after the terminal device powers on, it first identifies and initializes the multiple built-in SIM cards, selecting the primary data SIM card from operator A as the initial SIM card (i.e., the default card), ensuring that all SIM cards are correctly identified and in standby mode. When the platform issues a SIM card switching command, the application layer switches to the specified operator's SIM card according to the command. It's important to note that when a platform SIM card switching command exists, the application layer will prioritize executing the command-driven switching, ignoring other automatic switching conditions.

[0054] In this embodiment, the card switching order is the primary data SIM card of operator A and the secondary data SIM card of another operator. The default setting upon power-on is the primary data SIM card.

[0055] In one possible implementation, when the first data SIM card is connected to the terminal device through the application layer, the operator's primary data SIM card disconnects the first data SIM card from the terminal device according to the card-switching instruction and establishes a connection between the second data SIM card and the terminal device; when the second data SIM card is connected to the terminal device through the application layer, the operator's primary data SIM card disconnects the second data SIM card from the terminal device according to the card-switching instruction and establishes a connection between the operator's primary data SIM card and the terminal device.

[0056] In this embodiment, the SIM card switching order is: primary data SIM card from operator A - first data SIM card from operator B - second data SIM card from operator C. Upon power-up, the primary data SIM card is used by default. Therefore, according to the preset SIM card switching order, the application layer switches to the next SIM card.

[0057] In other words, it supports switching SIM cards via platform commands, allowing users to switch to a specific carrier's SIM card (manual card switching).

[0058] In one possible implementation, if both the primary data SIM card and the secondary data SIM card cannot access the network when connected to the terminal device, then the primary data SIM card establishes a connection between itself and the terminal device.

[0059] Specifically, the process is executed after the SIM card switching condition is triggered, switching SIM cards sequentially according to the preset switching order. If all three SIM cards fail to register on the network, the process will cycle through the switching three times and then remain on the primary data SIM card of the operator.

[0060] In other words, if the newly switched SIM card cannot access the internet, switch SIM cards. If none of the three SIM cards can register for the internet, repeat the switching process three times (you can set it according to your situation), and then stay on the main data SIM card of the operator.

[0061] It's important to clarify that "inability to access the internet" refers to the inability of a terminal device (such as a mobile phone) to connect to the internet via the SIM card, meaning it cannot access network services such as browsing web pages or downloading data. This can be due to various reasons, including but not limited to: * **No Service:** The terminal device does not detect the SIM card's signal at all; that is, the device cannot recognize or connect to the network provided by the SIM card. This is usually manifested as the device displaying "No Service" or a similar message. * **Limited Service:** In some cases, the SIM card may be subject to certain restrictions (such as carrier restrictions or regional restrictions), preventing the device from accessing network services. This may not necessarily manifest as "No Service," but the device still cannot access the internet. * **Insufficient Signal Strength:** Even if the device can detect the SIM card's signal, insufficient signal strength can also lead to an inability to access the internet. Signal strength is affected by various factors, such as geographical location and building obstructions. * **Network Incompatibility:** If the network standard provided by the SIM card is incompatible with the terminal device's network standard (e.g., the device only supports 4G, but the SIM card only provides 3G service), it can also result in an inability to access the internet.

[0062] In step S102, when the integrated card is installed on the terminal device, the operator's main data card obtains the network connection status detected by the terminal device according to the preset automatic switching instruction, and the operator's main data card controls the corresponding operator's main data card or operator's secondary data card to communicate with the terminal device according to the network connection status.

[0063] In one possible implementation, the network connection status includes signal strength, network service, and network standard. When the operator's primary data SIM card does not receive the handover instruction, and the terminal device moves from a first location to a second location, the operator's primary data SIM card obtains the signal strength, network service, and network standard of the terminal device at the second location according to a preset automatic handover instruction; or when the operator's primary data SIM card does not receive the handover instruction, the operator's primary data SIM card obtains the signal strength, network service, and network standard of the terminal device at preset time intervals according to a preset automatic handover instruction.

[0064] Specifically, in one embodiment, the application layer obtains the network connection status when the terminal device moves from one location to another; in another embodiment, the application layer obtains the network connection status at regular intervals. These intervals can be configured according to actual needs and are not specifically limited here.

[0065] It should be noted that the application layer automatically switches SIM cards on terminal devices based on network connection status (signal strength, network service, network standard). Switching is based on a set signal strength threshold, which can be configured according to customer requirements; switching is based on network service, including normal and abnormal network services, with abnormal network services further including no service and restricted service; and switching is based on network standard, with 4G > 3G > 2G.

[0066] In one possible implementation, when multiple signal strengths detected in a first consecutive number of iterations are no signal or the corresponding multiple network services are abnormal services, the operator's primary data SIM card controls the corresponding operator's primary data SIM card or the operator's secondary data SIM card to communicate with the terminal device according to a preset SIM card switching order; wherein, the abnormal services include no service and restricted service; when multiple signal strengths detected in a second consecutive number of iterations are lower than a signal strength threshold or the corresponding multiple network standards are lower than a network standard threshold, the operator's primary data SIM card controls the corresponding operator's primary data SIM card or the operator's secondary data SIM card to communicate with the terminal device according to the preset SIM card switching order (i.e., data SIM card switching).

[0067] Specifically, the system performs three consecutive signal strength checks on the current SIM card. If the signal strength falls below a set threshold (-115dB), the SIM card switching condition is triggered. It also performs five consecutive network service checks, with 30-second intervals between each check (150 seconds total). If these conditions are met, the SIM card switching condition is triggered. Finally, it checks if the current network type is 4G. If it drops to 3G or lower, and this occurs three times consecutively, the SIM card switching condition is triggered. These three checks are parallel; meeting any one of them will trigger the SIM card switching logic.

[0068] In this embodiment, the SIM card switching logic is as follows: the application layer switches SIM cards when any one of the following conditions is met: First, if the detection conditions (no signal, no service, limited service) are detected 5 times consecutively (the first consecutive count) and the detection time is 150 seconds, the card will be switched to the next card (if any one of these conditions is met); Second, if the detection conditions (signal strength, network type) are detected 3 times consecutively (the second consecutive count), and the signal strength is lower than the threshold (e.g., -115dB) or 4G changes to 3G, the card will be switched to the next SIM card.

[0069] In one possible implementation, when a preset number of data SIM card switching operations have been performed, the operator's primary data SIM card establishes a connection between itself and the terminal device and stops data SIM card switching until the network connection status meets a preset requirement. Based on the network connection status, the operator's primary data SIM card controls the corresponding operator's primary data SIM card or operator's secondary data SIM card to communicate with the terminal device (i.e., perform data SIM card switching).

[0070] Specifically, if a SIM card triggers 9 consecutive SIM card switching attempts, it will remain on the carrier's primary data SIM card and wait for signal strength and network compatibility to return to normal. After recovery, the application layer will allow normal SIM card switching again after 6-12 minutes. This step is a supplement to the SIM card switching logic to prevent instability and resource waste caused by frequent switching. When the limit for the number of SIM card switching attempts is reached, it will enter a waiting state until the recovery conditions are met.

[0071] In this embodiment of the application, if the SIM card triggers card switching 9 times (preset number of times) consecutively, it will remain in the operator's main data card until the signal strength is higher than the set threshold, the network standard is 4G, and after 6-12 minutes after returning to normal, normal card switching can be performed.

[0072] Next, with reference to the accompanying drawings, an intelligent switching system for an integrated card according to an embodiment of this application is described.

[0073] Figure 5 This is a structural diagram of the intelligent switching system of the integrated card according to an embodiment of this application.

[0074] like Figure 5 As shown, the intelligent switching system of the integrated card includes: an instruction switching module 100 and an automatic switching module 200.

[0075] Specifically, the instruction switching module 100 is used to control the corresponding operator traffic master card or the operator traffic slave card to communicate with the terminal device according to the instruction when the integrated card is installed on the terminal device and the operator traffic master card obtains the user's card switching instruction for the terminal device.

[0076] The automatic switching module 200 is used to, when the integrated card is installed on the terminal device, obtain the network connection status detected by the terminal device according to the preset automatic switching instruction, and control the corresponding operator traffic master card or operator traffic slave card to communicate with the terminal device according to the network connection status.

[0078] The memory 501, the processor 502, and the computer program stored on the memory 501 and capable of running on the processor 502.

[0079] When the processor 502 executes the program, it implements the intelligent switching method for the integrated card provided in the above embodiments.

[0080] Furthermore, the integrated card also includes:

[0081] Communication interface 503 is used for communication between memory 501 and processor 502.

[0082] The memory 501 is used to store computer programs that can run on the processor 502.

[0083] The memory 501 may include high-speed RAM memory, and may also include non-volatile memory, such as at least one disk storage device.

[0084] If the memory 501, processor 502, and communication interface 503 are implemented independently, they can be interconnected via a bus to communicate with each other. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EIS) bus, etc. Buses can be categorized as address buses, data buses, control buses, etc. For ease of representation, only one thick line is used in the diagram, but this does not indicate that there is only one bus or one type of bus.

[0085] Optionally, in a specific implementation, if the memory 501, processor 502, and communication interface 503 are integrated on a single chip, then the memory 501, processor 502, and communication interface 503 can communicate with each other through an internal interface.

[0086] Processor 502 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of this application.

[0087] This embodiment also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described intelligent switching method for integrated cards.
