[0002] Multi-WAN (Wide Area Network) communication equipment is only configured with cellular wireless links when it leaves the factory. However, in the actual network deployment environment, users may configure wired links based on cellular wireless links as needed, thus forming a situation where multiple networks, including cellular wireless links and wired links, are accessed simultaneously. Therefore, switching between the main link and links is involved to ensure the continuity and stability of the network.

[0003] Currently, the existing technology usually directly uses a wired link or a cellular wireless link as the main link of the network.

DETAILED DESCRIPTION

[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] Figure 1 A schematic diagram of a network switching method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the specific application scenario of the present application includes a user terminal 101 and a multi-WAN communication device 102 .

The multi-WAN communication device 102 performs network switching according to the network link configuration type.

[0049] Multi-WAN (Wide Area Network) communication equipment is only configured with cellular wireless links when it leaves the factory. However, in the actual network deployment environment, users may configure wired links based on cellular wireless links as needed, which results in multiple networks of cellular wireless links and wired links being accessed at the same time. Therefore, the main link and switching between links are involved to ensure the continuity and stability of the network. At present, the existing technology usually directly uses wired links or cellular wireless links as the main links of the network. However, directly using wired links or cellular wireless links as the main links of the network results in the inability of multi-WAN communication equipment to perform network switching in a timely manner in different application scenarios, reducing the flexibility of network switching.

[0050] In order to solve the above technical problems, the embodiments of the present application propose the following technical ideas: Considering that multi-WAN communication devices cannot perform network switching in time in different application scenarios. The inventor thought of setting a variety of network link configuration types to adapt to multiple application scenarios, including: only configuring wired links, only configuring cellular wireless links, cellular wireless links first, and wired links first. Determine the network link configuration type set by the user end, and perform different network switching operations in different application scenarios corresponding to different network link configuration types, so that multi-WAN communication devices can flexibly switch network links in different application scenarios, thereby improving the flexibility of network switching.

[0051] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are 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 repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Figure 2 A flowchart of a network switching method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method includes:

[0053] S20: Receive network link configuration data sent by the user terminal; wherein the network link configuration data includes a network link configuration type.

[0054] The network link configuration data is obtained by configuring the user end according to the usage scenario of multiple WAN communication devices.

[0055] In this embodiment, the network link configuration types include: configuring only wired links, configuring only cellular wireless links, giving priority to cellular wireless links, and giving priority to wired links.

[0056] In this embodiment, if the network link configuration type is to configure only wired links, step S201 is executed; if the network link configuration type is to configure only cellular wireless links, step S202 is executed; if the network link configuration type is cellular wireless links first, step S203 is executed; if the network link configuration type is wired links first, step S204 is executed.

[0057] S201: When the network link configuration type is to configure only the wired link, if the wired link is connected, the wired link is used.

[0058] Optionally, if the multi-WAN communication device is located in an area without 4G or 5G signal coverage, the satellite signal is good and it is necessary to access the wired satellite network to ensure normal service. At this time, the user end needs to set the network link configuration type to only configure the wired link, and only needs to detect whether the wired link is connected. If the wired link is connected, normal data service is carried out; if the wired link is not connected, the abnormal recovery process of the wired link is attempted, such as redialing and checking the physical connection.

[0059] Optionally, the connectivity of the wired link may be detected by pinging a server or the like.

[0060] S202: When the network link configuration type is to configure only the cellular wireless link, perform the following steps.

[0061] Specifically, step S202 includes S2021 to S2024:

[0062] S2021: Determine whether the cellular wireless link is connected.

[0063] S2022: If the cellular wireless link is connected, use the cellular wireless link.

[0064] S2023: If the cellular wireless link is not connected, determine whether to allow WIFI to switch to STA mode based on the network link configuration data.

[0065] S2024: If the WIFI is allowed to switch to the STA mode, obtain available WIFI within the preset network service range, and switch the network to the available WIFI; and switch to the cellular wireless link when the cellular wireless link is connected.

[0066] Among them, when the network link configuration type is to configure only the cellular wireless link, the specific operation will be described in detail in the subsequent embodiments.

[0067] S203: When the network link configuration type is cellular wireless link priority, perform the following steps.

[0068] Specifically, step S203 includes S2031 to S2033:

[0069] S2031: Determine whether the signal-to-noise ratio threshold and the reference signal received power threshold in the network link configuration data are empty.

[0070] S2032: If the signal-to-noise ratio threshold and the reference signal received power threshold are both empty, determine whether the cellular wireless link is connected.

[0071] Sa: If the cellular wireless link is connected, use the cellular wireless link;

[0072] Sb: If the cellular wireless link is not connected but the wired link is connected, the network is switched to the wired link; when the cellular wireless link is connected, it is switched to the cellular wireless link again;

[0073] S2033: If both the signal-to-noise ratio threshold and the reference signal received power threshold are not empty, determining whether the cellular wireless link in the current network service area meets the usage conditions;

[0074] Sc: If satisfied, use the cellular wireless link in the current network service area;

[0075] Sd: If not, the network will be switched to the cellular wireless link corresponding to the adjacent network service area that meets the usage conditions.

[0076] Among them, when the network link configuration type is cellular wireless link priority, the specific operation will be described in detail in the subsequent embodiments.

[0077] S204: When the network link configuration data is wired link priority, perform the following steps.

[0078] Specifically, step S204 includes S2041 to S2043:

[0079] S2041: Determine whether there is preset positioning area data in the network link configuration data;

[0080] S2042: If the preset positioning area data does not exist in the network link configuration data, determine whether the wired link is connected;

[0081] Se: If the wired link is connected, use the wired link;

[0082] Sf: If the wired link is not connected but the cellular wireless link is connected, the network is switched to the cellular wireless link; when the wired link is connected, it is switched to the wired link again;

[0083] S2043: If there is preset positioning area data in the network link configuration data, determine whether the current network service area is within the preset positioning area data range;

[0084] Sg: If it is not within the preset positioning area data range and the wired link is connected, the wired link is used;

[0085] Sh: If it is within the preset positioning area data range and the cellular wireless link is connected, the network will be switched to the cellular wireless link. If the cellular wireless link is not connected, it will be switched to the wired link.

[0086] Among them, when the network link configuration type is wired link priority, the specific operation will be described in detail in the subsequent embodiments.

[0087] In summary, the user terminal sets multiple network link configuration types including: only wired link configuration, only cellular wireless link configuration, cellular wireless link priority and wired link priority. By judging the network link configuration type set by the user terminal, the corresponding link connection is executed in different application scenarios corresponding to different network link configuration types, so that multiple WAN communication devices can flexibly switch network links in different application scenarios, thereby improving the flexibility of network switching.

[0088] Based on the above embodiment, in this embodiment, the processing process when the network link configuration type is to configure only a cellular wireless link is described in detail, as follows:

[0089] S501: When the network link configuration type is to configure only the cellular wireless link, perform the following steps.

[0090] Optionally, if multi-WAN communication devices are located in some remote areas, mountainous areas and islands where wired links are difficult to cover or the cost is too high, as well as some temporary places such as outdoor exhibitions and pop-up stores where wired links cannot be accessed, only cellular wireless links can be configured.

[0091] S5011: Determine whether the cellular wireless link is connected.

[0092] Optionally, the connectivity of the cellular wireless link may be detected by pinging a server or the like.

[0093] S5012: If the cellular wireless link is connected, use the cellular wireless link.

[0094] S5013: If the cellular wireless link is not connected, determine whether to allow WIFI to switch to STA mode according to the network link configuration data.

[0095] In this embodiment, the network link configuration data also includes configuration data on whether to allow WIFI to switch to STA mode.

[0096] Optionally, if the cellular wireless link is not connected, you need to consider whether to allow Wi-Fi to switch from the default AP (Access Point) mode to the STA (Station) mode. The Wi-Fi of gateway devices such as CPE (Customer Premises Equipment) works in AP mode by default.

[0097] Specifically, when the cellular wireless link is disconnected, abnormal recovery processing is performed on the cellular wireless link, so that when the cellular wireless link is connected, the network is switched to the cellular wireless link. Optionally, abnormal recovery processing includes but is not limited to SIM card switching, frequency locking, and restarting the protocol stack.

[0098] S5014: If the WIFI is allowed to switch to the STA mode, obtain available WIFI within the preset network service range, and switch the network to the available WIFI; and switch to the cellular wireless link when the cellular wireless link is connected.

[0099] In this embodiment, if the WIFI is allowed to switch to the STA mode, the working mode of the WIFI is switched to the STA mode, and the existing WIFI network nearby is searched and connected within the preset network service range. Optionally, if no available WIFI is obtained within the preset network service range, the network is switched to the cellular wireless network.

[0100] In summary, on the one hand, when multi-WAN communication equipment is located in some remote areas, mountainous areas and islands where wired links are difficult to cover or the cost is too high, configuring only cellular wireless links can reduce costs; on the other hand, when the cellular wireless link fails, allowing WIFI to switch to STA mode, the system can automatically switch to a nearby WIFI network, thereby ensuring the continuity of the network connection.

[0101] Based on the above embodiment, in this embodiment, the processing process when the network link configuration type is cellular wireless link priority is described in detail, as follows:

[0102] S601: When the network link configuration type is cellular wireless link priority, perform the following steps.

[0103] Specifically, step S601 includes S6011 to S6013:

[0104] S6011: Determine whether the signal-to-noise ratio threshold and the reference signal received power threshold in the network link configuration data are empty.

[0105] In this embodiment, the network link configuration data also includes whether a signal-to-noise ratio threshold and a reference signal received power threshold are set.

[0106] Among them, Signal to Interference & Noise Ratio (SINR) is the signal to interference plus noise ratio, which is the ratio of the strength of the received useful signal to the strength of the received interference signal. Reference Signal Receiving Power (RSRP) is one of the key parameters for measuring the strength of wireless signals in LTE networks. It represents the average value of the signal power received on all resource elements carrying reference signals in a symbol.

[0107] S6012: If the signal-to-noise ratio threshold and the reference signal received power threshold are both empty, determine whether the cellular wireless link is connected.

[0108] Sa: If the cellular wireless link is connected, use the cellular wireless link;

[0109] Sb: If the cellular wireless link is not connected but the wired link is connected, the network is switched to the wired link; when the cellular wireless link is connected, it is switched to the cellular wireless link again.

[0110] Specifically, when the cellular wireless link is not connected, abnormal recovery processing is performed on the cellular wireless link, so that when the cellular wireless link is connected, the network is switched to the cellular wireless link.

[0111] S6013: If both the signal-to-noise ratio threshold and the reference signal received power threshold are not empty, determine whether the cellular wireless link in the current network service area meets the usage conditions.

[0112] Specifically, the signal-to-noise ratio and reference signal received power of the current network service area are obtained; if the signal-to-noise ratio is greater than the signal-to-noise ratio threshold, and the reference signal received power is greater than the reference signal received power threshold, it is determined that the cellular wireless link in the current network service area meets the usage conditions.

[0113] Sc: If satisfied, use the cellular wireless link in the current network service area;

[0114] Sd: If not, the network will be switched to the cellular wireless link corresponding to the adjacent network service area that meets the usage conditions.

[0115] Specifically, through frequency locking technology, the network is switched to a cellular wireless link corresponding to an adjacent network service area that meets the usage conditions.

[0116] In this embodiment, if the SINR of the current network service area is less than the SINR threshold, or the RSRP is less than the RSRP threshold, that is, the cellular wireless link of the current network service area does not meet the usage conditions, it will switch to an adjacent network service area where the SINR is greater than the SINR threshold and the RSRP is greater than the RSRP threshold.

[0117] In this embodiment, multi-WAN communication devices are stationed in a cell with good signal by default, but sometimes the load of the cell with good signal is too high, or the signal of the current network service area is similar to that of the adjacent network service area. At this time, it is necessary to switch to the cellular wireless link of the adjacent network service area to avoid network jumping.

[0118] In this embodiment, when the cellular wireless link of the current network service area does not meet the usage conditions, and the cellular wireless link corresponding to the adjacent network service area also does not meet the usage conditions, it is determined whether the wired link is connected; if the wired link is connected, the network is switched to the wired link; when the cellular wireless link is connected, the network is switched to the cellular wireless link.

[0119] Optionally, if the cellular wireless links of the current network service area and the adjacent network service area do not meet the usage conditions, the frequency locking information is deleted.

[0120] In summary, when the network link configuration type is cellular wireless link priority, if there is no signal-to-noise ratio and reference signal receiving power threshold, when the cellular wireless link is not connected, it can switch to the wired link, further improving the flexibility of network switching; if there is a signal-to-noise ratio and reference signal receiving power threshold, it is possible to select a network service area with better signal quality for communication according to the signal-to-noise ratio and reference signal receiving power threshold, thereby improving the stability and reliability of the network connection.

[0121] Based on the above embodiment, in this embodiment, the processing process when the network link configuration type is wired link priority is introduced in detail, as follows:

[0122] S701: When the network link configuration data is wired link priority, perform the following steps.

[0123] Optionally, multi-WAN communication devices are used in the wilderness or in the vast ocean, where there is usually no 4G or 5G signal coverage, but the satellite signals and GPS reception signals in these places are very good. At this time, there is no need to use cellular wireless links, and wired links need to be accessed to ensure normal business. However, when multi-WAN communication devices move to areas covered by 4G or 5G signals, the satellite network fee is much higher than that of 4G and 5G, so wired links can be configured to take priority.

[0124] Specifically, step S701 includes S7011 to S7013:

[0125] S7011: Determine whether there is preset positioning area data in the network link configuration data.

[0126] In this embodiment, if the user terminal is configured with a positioning function, the network link configuration data also includes preset positioning area data.

[0127] Optionally, the preset positioning area data may be preset GPS area data.

[0128] S7012: If the preset positioning area data does not exist in the network link configuration data, determine whether the wired link is connected.

[0129] Se: If the wired link is connected, use the wired link.

[0130] Sf: If the wired link is not connected but the cellular wireless link is connected, the network is switched to the cellular wireless link; when the wired link is connected, it is switched to the wired link again;

[0131] S7013: If there is preset positioning area data in the network link configuration data, determine whether the current network service area is within the range of the preset positioning area data.

[0132] In this embodiment, the preset location area data is used to determine whether the multi-WAN communication device is located within a preset geographical range.

[0133] Sg: If it is not within the preset positioning area data range and the wired link is connected, the wired link is used.

[0134] Sh: If it is within the preset positioning area data range and the cellular wireless link is connected, the network will be switched to the cellular wireless link. If the cellular wireless link is not connected, it will be switched to the wired link.

[0135] In this embodiment, the multi-WAN communication device will check whether its current location is within the preset positioning area. If the multi-WAN communication device is not within the range of the preset positioning area data, the multi-WAN communication device will not detect the signal of the cellular wireless link and only use the wired link for communication; if the multi-WAN communication device moves within the range of the preset positioning area data, the device will detect the connectivity of the cellular wireless link. If the cellular wireless link is connected, it will switch to the cellular wireless link for communication; if the cellular wireless link is not connected, it will continue to use the wired link for communication.

[0136] Optionally, the latitude and longitude coordinates of the positioning signal may be compared to determine whether the positioning signal is within the range of the preset positioning area data.

[0137] In summary, when the network link configuration type is wired link priority, if there is no preset positioning area data, the cellular wireless link will not be detected, thereby avoiding unnecessary consumption of wireless resources.

[0138] If there is preset positioning area data, cellular wireless link detection can be enabled within the preset positioning area data range, providing flexible network configuration options, thereby improving the flexibility of network switching.

[0139] On the basis of the above embodiment, in this embodiment, when a cellular wireless link is involved in the network link configuration type, it is necessary to detect the signal quality to ensure that the multi-WAN communication devices can communicate normally, as described in detail as follows:
