[0070] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0071] With the development of science and technology and the increasing maturity of electronic device technology, the convenience of users' production and life has been improved. In electronic device application scenarios, users can access a wide variety of network resources through applications running on the operating system of the electronic device.

[0072] According to some embodiments, Figure 1 This diagram illustrates a background illustration of a network sharing method provided in an embodiment of this disclosure. For example... Figure 1 As shown, when a user accesses network resources through an application running on the operating system of an electronic device, the central processing unit (CPU) in the electronic device can utilize the TCP / IP 4-layer network architecture to have network card functionality. Consequently, the CPU can have network connectivity, and the user can access network resources through the application controlled by the CPU.

[0073] In some embodiments, Figure 2 This diagram illustrates a system architecture of a network sharing method provided by an embodiment of this disclosure. Figure 2As shown, when electronic device 11 receives a request for network resources in the application, electronic device 11 can send the request to server 13 via network 12. Then, server 13 can obtain the network resources corresponding to the request and send the network resources to electronic device 11 via network 12.

[0074] It's easy to understand that when the TCP / IP Layer 4 network architecture within a central processing unit (CPU) is incomplete, the CPU lacks network interface card (NIC) functionality. In this case, users cannot access network resources through applications controlled by that CPU.

[0075] The present disclosure will now be described in detail with reference to specific embodiments.

[0076] In embodiments of this disclosure, such as Figure 3 As shown, Figure 3 The diagram illustrates a flowchart of a network sharing method provided in an embodiment of this disclosure. This method can be applied, for example, to a first central processing unit (CPU) in a scenario where the CPU does not have a physical network interface card (NIC). The method can be implemented using a computer program and can run on an apparatus for performing network sharing. This computer program can be integrated into an application or run as a standalone utility application.

[0077] The network sharing device can be an electronic device with liquid detection capabilities, including but not limited to: wearable devices, handheld devices, personal computers, tablets, in-vehicle devices, smartphones, computing devices, or other processing devices connected to a wireless modem. In different networks, electronic devices may be called by different names, such as: user equipment, access electronic device, user unit, user station, mobile station, mobile station, remote station, remote electronic device, mobile device, user electronic device, electronic device, wireless communication device, user agent or user device, cellular phone, cordless phone, personal digital assistant (PDA), 5G network, 4G network, 3G network, or electronic devices in future evolved networks.

[0078] Specifically, the network sharing method includes:

[0079] S101, obtains data transmission instructions through the application controlled by the first central processing unit;

[0080] According to some embodiments, a central processing unit (CPU) refers to the final execution unit for information processing and program execution. This CPU can serve as the operational and control core of a computer system. The CPU is a very large-scale integrated circuit and can be composed of components such as logic units, register units, and control units.

[0081] In some embodiments, the first central processing unit (CPU) refers to a CPU without network capabilities. This first CPU does not specifically refer to a particular fixed processor. For example, the first CPU can change when the components it comprises change. The first CPU can also change when the circuitry corresponding to it changes.

[0082] In some embodiments, an application refers to a computer program designed to perform one or more specific tasks. The application does not specifically refer to a particular application. It includes, but is not limited to, music applications, time applications, and so on.

[0083] In some embodiments, a data transmission instruction refers to an instruction obtained by an application controlled by a first central processing unit when an electronic device shares data over a network. This data transmission instruction is not specifically defined by any single instruction. It includes, but is not limited to, voice data transmission instructions, click-to-transmit data transmission instructions, and so on. When the electronic device receives an instruction to modify the data transmission instruction, the data transmission instruction can change.

[0084] It is easy to understand that when an electronic device shares data over a network, it can obtain data transmission instructions through an application controlled by the first central processing unit.

[0085] S102, obtain the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command;

[0086] According to some embodiments, a socket is an abstraction of an endpoint for bidirectional communication between application processes on different hosts in a network. A socket is one end of process communication on the network, providing a mechanism for application-layer processes to exchange data using network protocols. The socket does not specifically refer to a particular fixed socket. For example, when a socket is connected to an application process upstream and a network protocol stack downstream, the socket can be an interface for the application to communicate via network protocols. The socket can also be an interface for the application to interact with the network protocol stack.

[0087] According to some embodiments, shared data refers to the data that an electronic device needs to share when sharing over a network. This shared data does not specifically refer to any single, fixed data. For example, the shared data may change when the application changes. The shared data may also change when the data transmission instructions change.

[0088] It is easy to understand that when an electronic device receives a data transmission command, it can obtain the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command.

[0089] S103, the socket is invoked to send shared data to the second central processing unit through the proxy module and the cross-core communication module set, so that the second central processing unit responds to the data transmission command and transmits the shared data to the network device based on the physical network card in the second central processing unit.

[0090] According to some embodiments, a proxy module refers to a module that controls indirect connections between one electronic device and another electronic device. The proxy module is not specifically defined as a single, fixed module. For example, the proxy module can change when the socket changes. It can also change when the first central processing unit changes.

[0091] According to some embodiments, the cross-core communication module RPMSG (OpenAMP) refers to a module used to support inter-core communication between different central processing units (CPUs). This cross-core communication module does not specifically refer to a single, fixed module. For example, when the first CPU changes, the cross-core communication module corresponding to that first CPU can change. When the second CPU changes, the cross-core communication module corresponding to that second CPU can change.

[0092] In some embodiments, the cross-core communication module set refers to a collection comprised of at least one cross-core communication module. This cross-core communication module set does not specifically refer to a single, fixed module. For example, the cross-core communication module set can change when the cross-core communication modules change. It can also change when the data transmission instructions change.

[0093] According to some embodiments, the second central processing unit (CPU) refers to a CPU with networking capabilities. This second CPU does not specifically refer to a particular fixed processor. For example, the second CPU can change when the components it contains change. The second CPU can also change when the circuitry corresponding to it changes.

[0094] According to some embodiments, the first operating system in the second central processing unit and the second operating system in the first central processing unit are heterogeneous multi-core operating systems. A heterogeneous multi-core operating system refers to a system composed of multiple single-core or multi-core processors of different types. A heterogeneous multi-core operating system can be two completely physically isolated operating systems.

[0095] In some embodiments, an operating system refers to a computer program used to manage computer hardware and software resources. This operating system includes, but is not limited to, Android, iOS, and others.

[0096] In some embodiments, the first operating system refers to the operating system configured in the first central processing unit. The first operating system does not specifically refer to a particular fixed operating system. For example, the first operating system may change when the first central processing unit changes. The first operating system may also change when the electronic device receives system modification instructions for the first operating system.

[0097] In some embodiments, the second operating system refers to the operating system configured in a second central processing unit. This second operating system is not specifically defined as a single, fixed operating system. For example, the second operating system may change when the second central processing unit changes. The second operating system may also change when the electronic device receives system modification instructions for that operating system.

[0098] In some embodiments, a physical network interface card (NIC) is a hardware device that connects the network protocol stack in the central processing unit (CPU) kernel space to an external network, transmitting and receiving data in bitstream format (0s and 1s). One end of the physical NIC is the network protocol stack in the kernel space, and the other end is the external network. This physical NIC is not specifically a fixed NIC. For example, the physical NIC can change when the CPU changes.

[0099] According to some embodiments, a network device refers to a physical entity device connected to a network. The network device does not specifically refer to a single fixed device. The network device includes, but is not limited to, computers, hubs, switches, bridges, routers, gateways, network interface cards, wireless access points, printers and modems, fiber optic transceivers, fiber optic cables, etc.

[0100] It is easy to understand that when an electronic device obtains the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command, the electronic device can call the socket to send the shared data to the second central processing unit through the proxy module and the cross-core communication module set. Then, the electronic device can control the second central processing unit to respond to the data transmission command and transmit the shared data to the network device based on the physical network card in the second central processing unit.

[0101] In this embodiment, a data transmission command is obtained through an application controlled by a first central processing unit (CPU). The CPU then obtains the socket corresponding to the data transmission command and the shared data corresponding to the command. The socket is invoked to send the shared data to a second CPU via a proxy module and a cross-core communication module set. This causes the second CPU to respond to the data transmission command and transmit the shared data to a network device based on the physical network interface card (NIC) within the second CPU. Therefore, when data transmission is required through a first CPU that lacks a physical NIC, the data to be transmitted can be sent to a second CPU that has a physical NIC using a socket and a cross-core communication module set. The data can then be transmitted to a network device via the second CPU. Thus, even if a CPU in an electronic device lacks NIC capabilities, network resources can still be accessed through an application controlled by that CPU, thereby improving the convenience of network sharing.

[0102] Please see Figure 4 , Figure 4 This diagram illustrates a flowchart of a network sharing method provided in an embodiment of this disclosure. This method can be applied, for example, to a scenario where a first central processing unit (CPU) does not have a physical network interface card (NIC). Specifically, the network sharing method includes:

[0103] S201, Obtain the proxy module call information sent by the second central processing unit;

[0104] The specific process is as described above, and will not be repeated here.

[0105] According to some embodiments, the proxy module call information refers to the information generated when the second central processing unit calls the proxy module in the first central processing unit. This proxy module call information does not specifically refer to any fixed information. For example, the proxy module call information may change when the proxy module changes. The proxy module call information may also change when the second central processing unit changes.

[0106] For example, when the second central processing unit calls the socket() corresponding to the proxy module usrsock in the first central processing unit, the second central processing unit can pass the call information of socket() to the first central processing unit.

[0107] It is easy to understand that when an electronic device performs network sharing, it can obtain proxy module call information sent by a second central processing unit.

[0108] S202, establish a socket on the first central processing unit and transmit the socket to the second central processing unit;

[0109] The specific process is as described above, and will not be repeated here.

[0110] According to some embodiments, when an electronic device establishes a socket on a first central processing unit, the established socket may be, for example, a UNIX socket. In this case, the first operating system can provide the user space with a seamless network sharing experience, thereby improving the convenience of network sharing.

[0111] In some embodiments, when the second central processing unit (CPU) transmits the call information for socket() to the first CPU, the electronic device can establish a socket on the first CPU, and then the electronic device can send the socket to the second CPU.

[0112] It is easy to understand that when an electronic device obtains the proxy module call information, the electronic device can establish a socket on the first central processing unit and transmit the socket to the second central processing unit.

[0113] S203, obtains data transmission instructions through the application controlled by the first central processing unit;

[0114] The specific process is as described above, and will not be repeated here.

[0115] According to some embodiments, Figure 5 This diagram illustrates a data transmission process according to an embodiment of the present disclosure. Figure 5 As shown, the interactive interface of the application controlled by the first central processing unit includes a data transfer button. When the electronic device detects that the user has clicked the data transfer button, the electronic device can obtain the data transfer command input for that button.

[0116] It is easy to understand that when an electronic device shares data over a network, it can obtain data transmission instructions through an application controlled by the first central processing unit.

[0117] S204, obtain the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command;

[0118] The specific process is as described above, and will not be repeated here.

[0119] According to some embodiments, when an electronic device receives a data transmission command, the socket corresponding to the data transmission command that the electronic device can obtain includes, but is not limited to, socket(), send(), recv(), send(), bind(), etc. For example, when the electronic device receives a data transmission command, it can obtain the socket send() corresponding to the data transmission command. The electronic device can also obtain the socket bind() corresponding to the data transmission command.

[0120] It is easy to understand that when an electronic device receives a data transmission command, it can obtain the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command.

[0121] S205, the socket is invoked to transmit shared data to the daemon process through the proxy module;

[0122] The specific process is as described above, and will not be repeated here.

[0123] According to some embodiments, a daemon process refers to a process that runs in the background of a first central processing unit and is not controlled by any electronic device. The daemon process is independent of the controlling electronic device and periodically performs a certain task or waits to process certain events. The daemon process can run without user input and provide a certain service. The daemon process is not specifically defined as a fixed process. For example, the daemon process can change when the task it performs changes. The daemon process can also change when the first central processing unit changes.

[0124] In some embodiments, the electronic device calls the socket send() function through an application controlled by the first central processing unit, so the electronic device can directly transmit shared data to the daemon usrsock client through the proxy module usrsock.

[0125] It is easy to understand that when an electronic device obtains the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command, the electronic device can call the socket to transmit the shared data to the daemon process through the proxy module.

[0126] S206, the control daemon transmits shared data to the service process of the second central processing unit through the cross-core communication module set, so that the second central processing unit responds to the data transmission command and transmits the shared data to the network device based on the physical network card in the second central processing unit;

[0127] The specific process is as described above, and will not be repeated here.

[0128] According to some embodiments, a service process refers to a program in the second central processing unit that is automatically executed by the system and does not require user interaction. The service process is not specifically defined as a single, fixed process. For example, the service process may change when the task it performs changes. The service process may also change when the second central processing unit changes.

[0129] For example, when an electronic device transmits shared data to the daemon process usrsockclient via the proxy module usrsock, the electronic device can control the daemon process usrsockclient to transmit the shared data to the service process usrsock server on the second central processing unit via a cross-core communication module set.

[0130] According to some embodiments, when the electronic device controls the daemon process to transmit shared data to the service process of the second central processing unit via a cross-core communication module set, the electronic device can control the daemon process to transmit the shared data to the second asymmetric multi-core communication module of the second central processing unit via the first asymmetric multi-core communication module, so that the service process containing the second asymmetric multi-core communication module can obtain the shared data. Therefore, the accuracy of the electronic device's transmission of shared data can be improved.

[0131] In some embodiments, an asymmetric multi-core communication module refers to a module that uses a small number of general-purpose processing cores to handle tasks requiring high software flexibility. Simultaneously, this asymmetric multi-core communication module can also employ a large number of hardware accelerators to handle even more tasks.

[0132] In some embodiments, the first asymmetric multi-core communication module refers to the asymmetric multi-core communication module corresponding to the first central processing unit in the cross-core communication module set. This first asymmetric multi-core communication module does not specifically refer to a fixed module. For example, when the first central processing unit changes, the first asymmetric multi-core communication module can change. Similarly, when the cross-core communication module set changes, the first asymmetric multi-core communication module can also change.

[0133] In some embodiments, the second asymmetric multi-core communication module refers to the asymmetric multi-core communication module corresponding to the second central processing unit in the cross-core communication module set. This second asymmetric multi-core communication module does not specifically refer to a fixed module. For example, the second asymmetric multi-core communication module can change when the second central processing unit changes. It can also change when the cross-core communication module set changes.

[0134] For example, when an electronic device transmits shared data to the daemon process usrsockclient via the proxy module usrsock, the electronic device can control the daemon process usrsockclient to transmit the shared data to the second asymmetric multi-core communication module OpenAMP2 via the first asymmetric multi-core communication module OpenAMP1.

[0135] It is easy to understand that when an electronic device calls a socket to transmit shared data to a daemon process through a proxy module, the electronic device can control the daemon process to transmit the shared data to a service process of the second central processing unit through a cross-core communication module set. Then, the electronic device can make the second central processing unit respond to the data transmission command and transmit the shared data to the network device based on the physical network card in the second central processing unit.

[0136] In this embodiment, by acquiring the proxy module call information sent by the second central processing unit (CPU), establishing a socket on the first CPU, and transmitting the socket to the second CPU, the efficiency of acquiring the socket corresponding to the data transmission command can be improved. The application controlled by the first CPU acquires the data transmission command; acquires the socket corresponding to the data transmission command and the shared data corresponding to the data transmission command; transmits the shared data to the daemon process through the proxy module by calling the socket; controls the daemon process to transmit the shared data to the service process of the second CPU through a cross-core communication module set, so that the second CPU responds to the data transmission command and transmits the shared data to the network device based on the physical network card in the second CPU. Therefore, when data transmission needs to be performed through the first CPU, which does not have a physical network card, the data to be transmitted can be sent to the second CPU, which has a physical network card, by using a socket and a cross-core communication module set, and then the data can be transmitted to the network device through the second CPU. Therefore, even if a CPU in an electronic device does not have network card capability, network resources can still be accessed through the application controlled by that CPU, thereby improving the convenience of network sharing.

[0137] The collection, storage, use, processing, transmission, provision, and disclosure of user personal information involved in the technical solution disclosed herein comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0138] Please see Figure 6 , Figure 6 This diagram illustrates a flowchart of a network sharing method provided in an embodiment of the present disclosure. The network sharing method is applied to a scenario where a second central processing unit (CPU) is equipped with a physical network interface card (NIC). Specifically, the network sharing method includes:

[0139] S301, obtains shared data sent by the first central processing unit through a cross-core communication module set;

[0140] According to some embodiments, sharing data refers to the first central processing unit (CPU) obtaining a data transmission instruction for an application and calling the socket corresponding to the data transmission instruction to send the data transmission instruction to the second CPU through the proxy module and cross-core communication module set of the first CPU.

[0141] In some embodiments, when an electronic device obtains shared data sent by a first central processing unit through a cross-core communication module set, the first central processing unit does not have a physical network interface card (NIC).

[0142] According to some embodiments, the cross-core communication module set includes a first asymmetric multi-core communication module in a first central processing unit and a second asymmetric multi-core communication module in a second central processing unit. When an electronic device obtains shared data sent by the first central processing unit through the cross-core communication module set, the electronic device can obtain the shared data sent by the first central processing unit through the first asymmetric multi-core communication module through the second asymmetric multi-core communication module.

[0143] It is easy to understand that when an electronic device shares data over a network, it can obtain the shared data sent by the first central processing unit through a set of cross-core communication modules.

[0144] S302, in response to a data transmission command, transmits shared data to network devices based on the physical network interface card;

[0145] According to some embodiments, when an electronic device transmits shared data to a network device based on a physical network card, the electronic device can encapsulate the data packet corresponding to the shared data in the kernel protocol stack of a second central processing unit, and then the electronic device can send the data packet to the network device based on the physical network card.

[0146] It is easy to understand that when an electronic device receives shared data sent by the first central processing unit, the electronic device can respond to the data transmission command and transmit the shared data to the network device based on the physical network card.

[0147] In this embodiment, shared data sent by the first central processing unit (CPU) is obtained through a cross-core communication module set. In response to a data transmission command, the shared data is transmitted to the network device based on the physical network interface card (NIC). Therefore, when data transmission is required through the first CPU, which lacks a physical NIC, the data to be transmitted can be sent to a second CPU equipped with a physical NIC using sockets and the cross-core communication module set. The second CPU can then transmit the data to the network device. Thus, even if a CPU in an electronic device lacks NIC capabilities, network resources can still be accessed through an application controlled by that CPU.
