[0069] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0070] 5G D2D (Device-to-Device) direct-connection technology refers to the ability for nearby terminals to transmit data directly within a short range without the need for base station relay. Due to its short-range and direct-connection advantages, D2D technology can improve the efficiency of wireless resource utilization and expand network coverage. In existing hybrid networks, terminals inevitably face the issue of choosing a communication mode.

[0071] Example 1

[0072] See Figure 1 This is a flowchart illustrating a network connection method provided in an embodiment of this disclosure. The provided network connection method is applied to a terminal device. Figure 1 As shown, the network connection method mainly includes the following steps:

[0073] Step S101: Determine whether the terminal device is in a preset state at the current device location;

[0074] The network connection method provided in this embodiment is applied to terminal devices, especially wireless communication terminal devices whose application location limits the deployment of wired networks. These devices typically connect to their local cell network via built-in wireless communication modules to achieve data communication with the outside world. However, due to factors such as cell signal quality or environmental conditions, some terminal devices may be unable to maintain a continuous and effective network connection, affecting normal communication. In summary, there is an urgent need for a method that can solve the above-mentioned technical problems, trigger the switching of D2D terminal mode when D2D wireless link resources are scarce or interference is severe, exchange necessary information based on the distance between the communicating parties detected by D2D communication, and select the communication mode based on a comparison of a specific threshold range, thereby overcoming the aforementioned problems.

[0075] This solution provides a network connection scheme for D2D networking communication in such situations, enabling terminal devices that cannot communicate normally to send and receive data through other devices that can communicate normally as intermediaries. In specific implementation, the device requiring network connection is defined as the terminal device, and the intermediary device capable of providing D2D networking communication is defined as the basic gateway device, thus limiting the gateway function of this part of the device to data relay. It should be noted that the basic gateway device can be a conventional standard gateway device, or a conventional terminal device capable of communication and D2D networking that can establish a wired communication connection with the standard gateway device. Here, it is only used to limit the installation of fixed-installation devices and wireless-to-wired devices appropriately arranged for D2D communication distances; no model restriction is imposed.

[0076] Considering that D2D networking can serve as an alternative network connection solution—meaning that terminal devices can choose D2D networking when their own wireless communication quality is poor or under other special circumstances, while still choosing conventional wireless communication under normal conditions—the state requiring D2D networking communication can be defined as a preset state. In this preset state, the terminal device needs to communicate via D2D networking. Therefore, the terminal device, at its current location, can periodically or proactively determine whether it is in the preset state when the network is abnormal. Considering practical applications, the preset state typically includes two main situations: a network connection error or low battery.

[0077] Step S102: If the terminal device is in the preset state at the current device location, it initiates a D2D networking request to at least one basic gateway device in the preset area where the current device location is located.

[0078] D2D networking requires a short distance. To establish a network, the network range needs to be defined with the feasible network distance as the radius, based on the current location of the terminal device. This range is defined as a preset area, which contains multiple basic gateway devices that may support networking. If the terminal device is in a preset state, it can initiate a D2D networking request to each basic gateway device within the preset area to request the establishment of a D2D network with one or more basic gateway devices within the preset area.

[0079] Step S103: If a network permission instruction is received from the target gateway device based on the D2D networking request, establish D2D networking communication with the target gateway device, wherein the target gateway device is any basic gateway device;

[0080] Based on the above steps, the terminal device initiates a D2D networking request to multiple basic gateway devices within the preset area. If a basic gateway device receives the D2D networking request and is in a network-enabled state, it can return a network-allowing instruction to the terminal device. Of course, for its own data security or load considerations, the basic gateway device may also choose not to return a network-allowing instruction, i.e., refuse to establish a D2D network with the terminal device.

[0081] The base gateway device that returns a network access permission instruction to the terminal device is defined as the target gateway device. The target gateway device can be a standard gateway device or a wired device connected to a standard gateway device. After receiving the network access permission instruction, the terminal device can establish D2D network communication with the target gateway device according to the algorithm strategy.

[0082] Step S104: Data transmission and reception are performed through the target gateway device.

[0083] After achieving D2D networking with the target gateway device through the above steps, data can be sent and received through the target gateway device, enabling communication with the outside world.

[0084] According to one specific embodiment of the present disclosure, the basic gateway device includes a standard gateway device and a wired device that establishes a wired communication connection with the standard gateway device;

[0085] The step of initiating a D2D networking request to at least one basic gateway device within a preset area where the current device is located, and establishing D2D networking communication with the target gateway device if a networking permission instruction is received from the target gateway device based on the D2D networking request, includes:

[0086] Locate the standard gateway devices and wired devices within the preset area;

[0087] Initiate a D2D networking request to the standard gateway device and the wired device;

[0088] If a network permission command is received from the standard gateway device, then D2D network communication is established with the standard gateway device;

[0089] If no network permission instruction is received from the standard gateway device, D2D network communication is established with the wired device.

[0090] Considering the varying communication capabilities of different gateway devices, this implementation method limits, for example... Figure 2 As shown, D2D networking communication is prioritized through standard gateway devices, followed by wired devices for D2D networking communication, in order to achieve more efficient network connectivity.

[0091] The basic gateway device can also be a wireless-to-wired device. If the basic gateway device is a wireless-to-wired device;

[0092] The step of initiating a D2D networking request to at least one basic gateway device within a preset area where the current device is located, and establishing D2D networking communication with the target gateway device if a networking permission instruction is received from the target gateway device based on the D2D networking request, includes:

[0093] Locate wireless-to-wired devices within the preset area;

[0094] Initiate a D2D networking request to the wireless-to-wired device;

[0095] If a network permission command is received from the wireless-to-wired device, then D2D network communication is established with the wireless-to-wired device.

[0096] If no network permission instruction is received from the wireless-to-wired device, a D2D network request is initiated to other terminal devices within the preset area.

[0097] This implementation adds the possibility of a basic gateway device including a wireless-to-wired (W2D) device, which can be a repeater router. A repeater router receives wireless signals, amplifies them, and converts them into a wired network. A repeater router with a network cable interface must be selected; otherwise, a wired network connection cannot be established. If a W2D device is found within the preset area, a D2D networking request is initiated directly to that device. After receiving a network permission command from the W2D device, D2D networking communication is established with it. If no network permission command is received, D2D networking requests need to be initiated to other terminal devices within the preset area.

[0098] According to a specific embodiment of this disclosure, the step for determining a preset state of abnormal network connection is limited. Specifically, the step of determining whether the terminal device is in a preset state at its current location includes:

[0099] Obtain the network registration information of the terminal device, and the signal quality of the cell corresponding to the current device location;

[0100] Based on the network registration information of the terminal device and the signal quality of the corresponding cell, it is determined whether the terminal device is in a network connection abnormal state;

[0101] If the terminal device is in a network connection abnormal state, it is determined that the terminal device is in the preset state at the current device location.

[0102] Furthermore, the network registration information includes network type, and the signal quality of the corresponding cell includes RSSI. The step of determining whether the terminal device is in a network connection abnormal state based on the network registration information of the terminal device and the signal quality of the corresponding cell includes:

[0103] Determine whether the network type of the corresponding cell matches the network type required by the terminal device for data traffic usage, and determine whether the RSSI of the corresponding cell is less than or equal to the signal strength threshold;

[0104] If the network type of the corresponding cell does not match the network type required by the terminal device for data traffic, or if the RSSI of the corresponding cell is less than or equal to the signal strength threshold, then the terminal device is determined to be in a network connection abnormal state.

[0105] This embodiment defines a networking scheme for situations where network connectivity is abnormal. Specifically, a terminal device at a fixed location obtains its own network registration information, such as network type, frequency band, or channel, as well as the RSSI (Signal Quality Standard) of the corresponding cell. If the cell signal quality is too poor, the device is disconnected from the network or network type, or the signal quality is below a certain threshold, then D2D networking is initiated. Of course, in practical implementation, considering that some fixed-location wireless devices cannot directly perform single-hop or wireless-to-wired D2D networking, multi-hop networking can also be used, that is, forwarding communication through multiple target gateway devices as intermediaries.

[0106] According to another specific embodiment of this disclosure, the case where the preset state is a low battery state is limited. Specifically, the step of determining whether the terminal device is in a preset state at the current device location includes:

[0107] Determine whether the current remaining battery power of the terminal device is less than or equal to a preset battery power threshold;

[0108] If the current remaining battery power of the terminal device is less than or equal to the preset battery power threshold, then the terminal device is determined to be in the preset state at the current location.

[0109] This implementation method limits the selection of a low-power D2D networking communication method under low power conditions, taking into account the high power consumption of the wireless communication module, thereby improving the applicability of network connectivity.

[0110] The network connection scheme in this embodiment deploys a basic gateway device that can convert wireless to wired connections at a convenient location for cabling. This provides D2D networking communication conditions for terminal devices in the surrounding area with poor network quality or other preset conditions, enabling terminal devices with communication needs to overcome location network limitations and send and receive data externally through the basic gateway device.

[0126] If a network permission command is received from the standard gateway device, then D2D network communication is established with the standard gateway device;

[0135] The network connection device in this embodiment first determines whether the terminal device is in a preset state at its current location. If the terminal device is in the preset state, it initiates a D2D networking request to at least one basic gateway device within the preset area where the current device is located. After receiving a network permission instruction from any target gateway device among the basic gateway devices based on the D2D networking request, D2D networking communication can be established with the target gateway device, thus enabling data transmission and reception through the target gateway device. In this solution, deploying basic gateway devices capable of wireless-to-wired conversion at convenient cabling locations provides D2D networking communication conditions for terminal devices in the surrounding area with poor network quality or other preset states, allowing terminal devices with communication needs to overcome location network limitations and achieve external data transmission and reception through the basic gateway devices.

Specifically, user input unit 407 includes a touch panel 4071 and other input devices 4072. Touch panel 4071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 4071). Touch panel 4071 may include two parts: a touch detection terminal device and a touch controller. The touch detection terminal device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection terminal device, converts it into touch point coordinates, and sends it to the processor 410, which receives and executes commands from the processor 410. In addition, touch panel 4071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. Besides touch panel 4071, user input unit 407 may also include other input devices 4072. Specifically, other input devices 4072 may include, but are not limited to, physical keyboards, function keys (such as volume control buttons, power buttons, etc.), trackballs, mice, joysticks, etc., which will not be described in detail here.

[0150] Furthermore, the touch panel 4071 can cover the display panel 4061. When the touch panel 4071 detects a touch operation on or near it, it transmits the information to the processor 410 to determine the type of touch event. Subsequently, the processor 410 provides corresponding visual output on the display panel 4061 based on the type of touch event. Although in Figure 4 In this embodiment, the touch panel 4071 and the display panel 4061 are two independent components to realize the input and output functions of the terminal device. However, in some embodiments, the touch panel 4071 and the display panel 4061 can be integrated to realize the input and output functions of the terminal device. The specific implementation is not limited here.

[0151] Interface unit 408 serves as an interface for connecting external terminal devices to terminal device 400.

Interface unit 408 can be used to receive input (e.g., data, power, etc.) from the external terminal device and transmit the received input to one or more components within terminal device 400, or it can be used to transmit data between terminal device 400 and the external terminal device.

[0152] The memory 409 can be used to store software programs and various data. The memory 409 may primarily include a program storage area and a data storage area. The program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 409 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0153] Processor 410 is the control center of the terminal device. It connects various parts of the terminal device via various interfaces and lines. By running or executing software programs and / or modules stored in memory 409, and by calling data stored in memory 409, it performs various functions and processes data of the terminal device, thereby providing overall monitoring of the terminal device. Processor 410 may include one or more processing units; preferably, processor 410 may integrate an application processor and a modem processor. The application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into processor 410.

[0154] The terminal device 400 may also include a power supply 411 (such as a battery) that supplies power to various components. Preferably, the power supply 411 can be logically connected to the processor 410 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0155] In addition, the terminal device 400 includes some functional modules not shown, which will not be described in detail here.

[0156] In addition, this application also provides a computer-readable storage medium storing computer instructions for causing a computer to perform the network connection method described in any one of the first aspects.

[0157] The terminal device and computer-readable storage medium in this embodiment first determine whether the terminal device is in a preset state at its current location. If the terminal device is in the preset state, it initiates a D2D networking request to at least one basic gateway device within the preset area where the current device is located. After receiving a network permission instruction from any target gateway device among the basic gateway devices based on the D2D networking request, D2D networking communication can be established with the target gateway device, thus enabling data transmission and reception through the target gateway device. In this solution, basic gateway devices capable of wireless-to-wired conversion are deployed in locations convenient for cabling, providing D2D networking communication conditions for terminal devices in the surrounding area with poor network quality or other preset states. This allows terminal devices with communication needs to overcome location network limitations and achieve external data transmission and reception through the basic gateway devices. The specific implementation process of the provided terminal device and computer-readable storage medium can be found in the specific implementation process of the network connection method provided in the above embodiments, and will not be repeated here.
