Technical Field

[0001] Embodiments of the present application relate to the field of communication technologies, and in particular, to a network switching method, apparatus, and electronic device. Background Art

[0002] Currently, the functions of mobile terminals are becoming more and more diverse. Mobile terminals can run various applications through the network to access service content, thereby meeting user needs. However, a mobile terminal device can only be connected to one network at the same time.

[0003] In the prior art, a mobile terminal device can save connection information of multiple networks at the same time. If the signal strength of the currently connected network is small, the network with the largest signal strength can be determined from the connection information of the multiple networks saved in the mobile terminal, and the mobile terminal device can be connected to this network.

[0077] Hereinafter, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0078] Refer to Figure 1 , Figure 1 It is a step flowchart of a network switching method provided by an embodiment of the present application, which is applied to a target device. The method includes:

[0079] Step 101, determine the network quality index difference between the first network quality index value corresponding to each candidate network and the target network quality index value of the target application scenario.

[0080] In the embodiments of the present application, the candidate networks may be WIFI, mobile networks, etc. Among them, the mobile network may include multiple operator networks, and the above networks can be used through an Embedded-SIM (eSIM). The target device may be a device with Internet access function and capable of storing the connected network information, such as intelligent devices like mobile phones, computers, tablets, in-vehicle devices, etc. The target device can start and use multiple independent applications simultaneously. Among them, different applications have different requirements for network quality. For example, an online video playback application requires a relatively high network bandwidth, a map navigation application requires a relatively low network latency, and a real-time voice call application requires a relatively low network latency and a relatively low packet loss rate. One or more independent application programs started simultaneously on the target device can jointly constitute the target application scenario. Since each independent application program has network quality requirements, therefore, the target application scenario can also have network quality requirements, and the network quality can be evaluated by network quality indicators. Therefore, the network quality requirement of the target application scenario is the target network quality indicator value. Among them, the network quality indicators may include, but are not limited to, network latency, network bandwidth, packet loss rate, signal strength, etc. On this basis, the first network quality indicator values corresponding to the candidate networks can be determined according to one or more of the above network quality indicators, and then the first network quality indicator values can be subtracted from the target network quality indicator values correspondingly, so that the network quality indicator difference between the first network quality indicator values and the target network quality indicator values can be determined. Among them, the network quality indicator difference can be the difference between two network quality indicator values corresponding to the network indicators of the relative type.

[0081] For example, if the first network quality indicator values of the candidate network are signal strength 60, network latency 40 ms, packet loss rate 20%, and bandwidth 200 Mbps, and the target network quality indicator values are signal strength 50, network latency 10 ms, packet loss rate 15%, and bandwidth 150 Mbps, then the network quality indicator difference is signal strength 10, network latency 30 ms, packet loss rate 5%, and bandwidth 50 Mbps.

[0082] Step 102, determine the index weight value of the target network quality indicator value based on the target application scenario.

[0083] In the embodiments of the present application, for a target application scenario, the weights between its corresponding target network quality indicators are usually different. And application scenarios can usually be in one-to-one correspondence with weight values. For example, the weight values of the network indicators required for online video playback applications may be different from those required for real-time voice call applications. Therefore, the indicator weight value corresponding to the target application scenario can also correspond to the target application scenario. On this basis, the indicator weight value corresponding to the target application scenario can be determined according to the weight values of the independent application scenarios included in the target application scenario, that is, the indicator weight value of the target network quality indicator value. For example, the arithmetic mean of the weight values of the independent application scenarios included in the target application scenario can be taken as the indicator weight value corresponding to the target application scenario, or the weight values of the independent application scenarios can be calculated according to the order of activation of the independent application scenarios and a preset weight distribution method to obtain the indicator weight value corresponding to the target application scenario.

[0084] Step 103: Based on the target network quality indicator value, the network quality indicator difference, and the indicator weight value, determine the first network quality score values corresponding to the multiple candidate networks respectively.

[0085] In the embodiments of the present application, since different network quality indicators correspond to different dimensions, therefore, the ratio between the network quality indicator difference and the target network quality indicator value can be calculated to obtain the dimension-normalized relative quality indicator difference, and then weighted summation is performed according to the relative quality indicator difference and the indicator weight value to obtain the first network quality score values corresponding to the multiple candidate networks respectively. When performing weighted summation, the relative quality indicator differences corresponding to all types of network quality indicators can be selected, or the relative quality indicator difference of the network quality indicator corresponding to the maximum value in the indicator weight value can be selected and multiplied by the maximum value of the indicator weight value to obtain the first network quality score value.

[0086] Step 104: Based on the first network quality score value, determine a target candidate network from the multiple candidate networks and switch to the target candidate network.

[0087] In the embodiments of the present application, after obtaining the first network quality score value of the candidate network, a target candidate network can be determined from the multiple candidate networks according to the first network quality score value, and the connection network of the target device can be switched to the target candidate network. For example, the candidate network corresponding to the maximum value of the first network quality score value can be used as the target candidate network, or the candidate network corresponding to the first network quality score value greater than or equal to a first threshold can be used as the target candidate network, and any one of the target candidate networks can be selected for switching when performing network switching.

[0088] In an embodiment of the present application, by determining the network quality index difference between the first network quality index values corresponding to the candidate networks and the target network quality index value of the target application scenario, determining the index weight value of the network quality index difference based on the target application scenario, and determining the first network quality score values corresponding to the multiple candidate networks based on the target network quality index value, the network quality index difference, and the index weight value, and determining the target candidate network from the multiple candidate networks based on the first network quality score value and switching to the target candidate network, the first network quality score value of the candidate network can be calculated according to the network quality index value of the candidate network and the target network quality index of the target application scenario, and the target candidate network can be screened out from the candidate networks according to the first network quality score value and switched to the target candidate network, so that the network can be automatically switched to the network with the highest adaptability to the target application scenario, which improves the network utilization rate and the networking efficiency to a certain extent.

[0089] Refer to Figure 2 , Figure 2 FIG. is a flowchart of steps of another network switching method provided by an embodiment of the present application. The method includes:

[0090] Step 201, when the first connection state of the current network is normal, execute the step of determining the network quality index difference between the first network quality indexes corresponding to the multiple candidate networks and the target network quality index of the target application scenario.

[0091] In an embodiment of the present application, the first connection state of the current network can be judged first. If the first connection state is normal, the step of determining the network quality index difference between the first network quality indexes corresponding to the multiple candidate networks and the target network quality index of the target application scenario can be executed to obtain the network quality index difference.

[0092] Step 202, when the first connection state is abnormal, perform network switching based on the user identification code type corresponding to the current network.

[0093] In an embodiment of the present application, if the first connection status of the current network is abnormal, the user identification code type corresponding to the current network can be determined, and network switching can be performed according to the user identification code type. If the user identification code type is the first identification code type, the first alternative network corresponding to the first identification code type can be selected from the alternative networks and switched to the first alternative network, where the first identification code type can be a service code number type, and the service code number is a user number and network number composed of numbers and symbols for implementing communication functions. These code numbers are used to identify specific communication services or users and are indispensable identity identifiers in communication; if the user identification code type is the second identification code type, it can be searched in the target device whether there is an available first alternative network corresponding to the first identification code type. If it exists, switch to the first alternative network. If it does not exist, the service code number corresponding to the first identification code type can be requested from a specified server through the configuration information of the current network, and the current network can be switched to the network corresponding to the service code number according to the service code number to complete network switching.

[0094] Optionally, in step 202, the following sub-steps may be included:

[0095] Sub-step 2021, when the user identification code type corresponding to the current network is the first identification code type and there is a first network corresponding to the first identification code type among the multiple alternative networks, determine the second connection status of the first network.

[0096] In an embodiment of the present application, if the user identification code type corresponding to the current network is the first identification code type, it can be determined whether there is a first network corresponding to the first identification code type among the alternative networks. If it exists, the second connection status of the first network can be determined.

[0097] Sub-step 2022, when the second connection status is normal, switch to the first network.

[0098] In an embodiment of the present application, if the second connection status of the first network is normal, the current network can be switched to the first network.

[0099] Sub-step 2023, when the user identification code type corresponding to the current network is the first identification code type and there is no first network corresponding to the first identification code type among the multiple alternative networks, determine the third connection status of the second network corresponding to the second identification code type among the multiple alternative networks; where the second identification code type is different from the first identification code type.

[0100] In an embodiment of the present application, if the user identification code type corresponding to the current network is the first identification code type, and there is no first network corresponding to the first identification code type in the candidate networks, the third connection state of the second network corresponding to the second identification code type can be determined from the candidate networks. The second identification code type may correspond to the global seed code number type, and communication with a specified server can be performed through the international communication network corresponding to the global seed code number. The second identification code type and the first identification code type may be different.

[0101] In a possible embodiment, if the user identification code type corresponding to the current network is the first identification code type, there is a first network corresponding to the first identification code type in the candidate networks, and the second connection states of the first networks are all abnormal connections, the third connection state of the second network corresponding to the second identification code type can also be determined from the candidate networks.

[0102] Sub-step 2024, when the third connection state is a normal connection, switch to the second network.

[0103] In an embodiment of the present application, if the third connection state of the second network is a normal connection, the current network can be switched to the second network.

[0104] Sub-step 2025, when the user identification code type corresponding to the current network is the second identification code type and the user identification code corresponding to the current network contains network configuration information, initialize the network connection of the current network based on the network configuration information and reconnect to the current network.

[0105] In an embodiment of the present application, if the user identification code type corresponding to the current network is the second identification code type, it can be determined whether the user identification code corresponding to the current network contains network configuration information. If the user identification code contains network configuration information, the network connection of the current network can be initialized according to the network configuration information, and after the initialization is completed, reconnect to the current network.

[0106] In a possible embodiment, as Figure 3 shown Figure 3It is a schematic flowchart of automatically switching networks provided by an embodiment of the present application. In the figure, the target device can automatically switch the current network to the first network corresponding to the first identification code type. Among them, the first identification code type usually corresponds to a service code number, and communication can be directly carried out through the operator network corresponding to the service code number. The target device can also connect to the second network corresponding to the second identification code type. Among them, the second identification code type usually corresponds to a global seed code number, and communication with a specified server can be carried out through the international communication network corresponding to the global seed code number. If the user identification code type corresponding to the current network of the target device is the second identification code type, first determine whether the current network has a configuration file. If there is no configuration file, the configuration file can be downloaded from the specified server and the current network can be initialized. Then, search in the target device to see if there is a first network corresponding to the available first identification code type. If there is a configuration file, search in the target device to see if there is a first network corresponding to the available first identification code type. If there is a first network, switch to the first network. If there is no first network, the service code number of the first identification code type can be requested and sent from the specified server through the configuration information of the current network, and the current network can be switched to the network corresponding to the service code number to complete the network switch.

[0107] In the embodiment of the present application, when the user identification code type corresponding to the current network is the first identification code type and there is a first network corresponding to the first identification code type among multiple candidate networks, determine the second connection status of the first network. When the second connection status is normal, switch to the first network. When the user identification code type corresponding to the current network is the first identification code type and there is no first network corresponding to the first identification code type among multiple candidate networks, determine the third connection status of the second network corresponding to the second identification code type among multiple candidate networks. Among them, the second identification code type is different from the first identification code type. When the third connection status is normal, switch to the second network. When the user identification code type corresponding to the current network is the second identification code type and the user identification code corresponding to the current network contains network configuration information, initialize the network connection of the current network based on the network configuration information and reconnect to the current network. The network switch can be pre-performed according to the user identification code type of the current network, which improves the network utilization rate and networking efficiency of the target device to a certain extent.

[0108] In an embodiment of the present application, when the first connection state of the current network is normal, the step of determining the network quality index differences between the first network quality indexes corresponding to multiple candidate networks and the target network quality index of the target application scenario is executed. When the first connection state is abnormal, network switching is performed based on the user identification code type corresponding to the current network. The network quality index differences can be determined when the first connection state of the current network is normal, and network switching can be performed according to the user identification code type corresponding to the current network when the connection is abnormal, which improves the availability of network communication of the target device to a certain extent.

[0109] Step 203, when the target application scenario includes multiple independent application scenarios, determine the second network quality index values and independent weight values corresponding to the multiple independent application scenarios respectively.

[0110] In an embodiment of the present application, if the target application scenario includes multiple independent application scenarios, since each independent application scenario corresponds to an independent weight value, the second network quality index values and independent weight values corresponding to the multiple independent application scenarios can be determined according to the network quality index type.

[0111] Step 204, perform weighted averaging on the second network quality index values based on the independent weight values to obtain the target network quality index value.

[0112] In an embodiment of the present application, for each independent application scenario, there is a corresponding relationship between the second network quality index value and the independent weight value. Therefore, according to this corresponding relationship, the second network quality index value and the independent weight value can be weighted averaged to obtain the target network quality index value.

[0113] For example, if the target application scenario includes an online video playback application and a map navigation application, where the second network quality index value of the online video playback application is signal strength 60, network latency 40 ms, packet loss rate 20%, and bandwidth 200 Mbps, and the independent weight values are 0.2, 0.2, 0.1, 0.5, and the second network quality index value of the map navigation application is signal strength 50, network latency 10 ms, packet loss rate 10%, and bandwidth 100 Mbps, and the independent weight values are 0.2, 0.5, 0.2, 0.1, then the target network quality index value of the target application scenario is signal strength (60×0.2 + 50×0.2) / (0.2 + 0.2), network latency (40×0.2 + 10×0.5) / (0.2 + 0.5) ms, packet loss rate (0.2×0.1 + 0.1×0.2) / (0.1 + 0.2), and bandwidth (200×0.5 + 100×0.1) / (0.5 + 0.1) Mbps, that is, signal strength 55, network latency 18.6 ms, packet loss rate 13.3%, and bandwidth 183.3 Mbps.

[0114] In an embodiment of the present application, when the target application scenario includes multiple independent application scenarios, by determining the second network quality index values and independent weight values respectively corresponding to the multiple independent application scenarios, and performing weighted averaging on the second network quality index values based on the independent weight values to obtain the target network quality index value, the weighted averaging method can be used to calculate the target network quality index value when the target application scenario includes multiple independent application scenarios, which improves the accuracy and reliability of the target network quality index value to a certain extent.

[0115] Step 205: Determine the network quality index difference between the first network quality index value corresponding to each candidate network and the target network quality index value of the target application scenario.

[0116] In an embodiment of the present application, the implementation content of this step can refer to the embodiment content of step 101 and will not be elaborated here.

[0117] Step 206: Determine the independent weight value corresponding to the independent application scenario.

[0118] In an embodiment of the present application, for an independent application scenario, its corresponding independent weight value can usually be stored at a specified location in the target device database. Therefore, the independent weight value corresponding to the independent application scenario can be determined from the database of the target device according to each specified location.

[0119] Step 207: Based on the independent weight value, determine the index weight value of the target network quality index value.

[0120] In an embodiment of the present application, the arithmetic mean of the weight values of the independent application scenarios included in the target application scenario can be taken as the index weight value corresponding to the target application scenario, or the weight values of the independent application scenarios can be calculated according to the start order of the independent application scenarios and the preset weight distribution method to obtain the index weight value corresponding to the target application scenario.

[0121] Continuing with the above example, if the independent weight values are 0.2, 0.5, 0.2, 0.1 and 0.2, 0.2, 0.1, 0.5, the index weight values can be 0.2, 0.35, 0.15, 0.3. If the weight distribution method for two independent application scenarios is "the weight of the online launched application is 0.6", and the map navigation application is launched before the online video playback application, the index weight values can be 0.2×0.6 + 0.2×0.4, 0.5×0.6 + 0.2×0.4, 0.2×0.6 + 0.1×0.4, 0.1×0.6 + 0.5×0.4, that is, 0.2, 0.38, 0.16, 0.26.

[0122] Optionally, step 207 may include the following sub-steps:

[0123] Sub-step 2071, when the target application scenario includes multiple independent application scenarios, determine the application priorities of the multiple independent application scenarios.

[0124] In the embodiments of the present application, for the target device, each independent application scenario may have an application priority. For example, for an in-vehicle multimedia device, the priority of the map navigation application may be higher than that of the online video playback application. On this basis, if the target application scenario includes multiple independent application scenarios, the priorities of the multiple independent application scenarios can be determined.

[0125] Sub-step 2072, based on the application priority and the independent weight value, determine the index weight value of the target network quality index value.

[0126] In the embodiments of the present application, the application priority may include a first priority and a second priority, and in multiple independent application scenarios, at most one independent application with the first priority can be started simultaneously. Among them, the weight assignment value of the first priority can be set to be greater than or equal to 0.5, and the weight assignment value of the second priority can be set to be less than or equal to 0.5. On this basis, the weight assignment values corresponding to the independent application scenarios can be determined according to the priorities of the independent application scenarios. For example, if the target application scenario includes four independent application scenarios, the weight assignment value of the independent application scenario with the first priority can be 0.5, and the weight assignment values of the independent application scenarios with the second priority can be 0.16, 0.17, 0.17.

[0127] In the embodiments of the present application, by determining the application priorities of multiple independent application scenarios when the target application scenario includes multiple independent application scenarios, and based on the application priority and the independent weight value, determining the index weight value of the target network quality index value, when the target application scenario includes multiple independent application scenarios, the index weight value of the target network quality index value can be determined according to the application priority and the independent weight value of the independent application scenario, which improves the adaptability of the index weight value to the actual network requirements to a certain extent and improves the reliability of the index weight value.

[0128] In the embodiments of the present application, by determining the independent weight value corresponding to the independent application scenario and based on the independent weight value, determining the index weight value of the target network quality index value, the index weight value of the target network quality index value can be calculated according to the independent weight value corresponding to the independent application scenario included in the target application scenario, which improves the accuracy of the index weight value to a certain extent.

[0129] Step 208: Calculate the ratio of the network quality indicator difference to the target network quality indicator value to obtain the network quality indicator missing ratio of the candidate network.

[0130] In an embodiment of the present application, the network quality indicator difference can be divided by the target network indicator value to obtain the ratio of the network quality indicator difference to the target network quality indicator value, and this ratio is used as the network quality indicator missing ratio of the candidate network.

[0131] For example, if the network quality indicator difference is signal strength 10, network latency 30 ms, packet loss rate 5%, and bandwidth 50 Mbps, and the target network quality indicator value is signal strength 50, network latency 10 ms, packet loss rate 15%, and bandwidth 150 Mbps, then the network quality indicator missing ratio is signal strength 20%, network latency 300%, packet loss rate 33.3%, and bandwidth 33.3%.

[0132] Step 209: Multiply the network quality indicator missing ratio by the indicator weight value correspondingly to obtain the indicator score value of the candidate network.

[0133] In an embodiment of the present application, the network quality indicator missing ratio can be multiplied by the indicator weight value of the target network quality indicator correspondingly to obtain the indicator score value of the candidate network.

[0134] Continuing with the above example, if the indicator weight values are 0.2, 0.35, 0.15, 0.3, and the network quality indicator missing ratio is signal strength 20%, network latency 300%, packet loss rate 33.3%, and bandwidth 33.3%, then the indicator score value of the candidate network is 0.04, 1.05, 0.05, 0.1.

[0135] Step 210: Determine the first network quality score value of the candidate network based on the indicator score value.

[0136] In an embodiment of the present application, after obtaining the indicator score value, the values included in the indicator score value can be added up to obtain the first network quality score value of the candidate network; or the average value of the values included in the indicator score value can be calculated to obtain the first network quality score value of the candidate network.

[0137] Continuing with the above example, if the indicator score value is 0.04, 1.05, 0.05, 0.1, then the first network quality score value can be 0.04 + 1.05 + 0.05 + 0.1 = 1.24.

[0138] In an embodiment of the present application, by calculating the ratio of the difference in network quality indicators to the target network quality indicator value, the missing ratio of the network quality indicators of the candidate network is obtained. The missing ratio of the network quality indicators is multiplied by the indicator weight value correspondingly to obtain the indicator score value of the candidate network. Based on the indicator score value, the first network quality score value of the candidate network is determined. The difference in network quality indicators can be dimensionally normalized, and the first network quality score value of the candidate network can be calculated by means of weighted summation, which improves the usability of the first network quality score value.

[0139] Step 211, determine that the candidate network corresponding to the maximum value of the first network quality score value is the target candidate network, or determine that the candidate network corresponding to the first network quality score value greater than or equal to the first threshold is the target candidate network.

[0140] In an embodiment of the present application, the maximum value of the first network quality score value can be screened out from the first network quality score values, and the candidate network corresponding to the maximum value can be used as the target candidate network. Alternatively, the score values greater than the first threshold can be screened out from the first network quality score values, and the candidate networks corresponding to the score values greater than the first threshold can be used as the target candidate networks. After the target candidate network is determined, the target device can be switched to the target candidate network.

[0141] In an embodiment of the present application, by determining that the candidate network corresponding to the maximum value of the first network quality score value is the target candidate network, or determining that the candidate network corresponding to the first network quality score value greater than or equal to the first threshold is the target candidate network, the target device can be switched to the target candidate network with a higher network quality score value, which improves the network utilization rate to a certain extent.

[0142] See Figure 3 , Figure 3A data flow diagram of a network switching method provided by an embodiment of this application. In the figure, the process can start first, and then the connection status of the current network can be judged. If the connection is normal, the target network quality index value and the index weight value of the target application scenario are calculated. If the connection is abnormal, the user identification code type of the current network is judged. If it is the first identification code type, switch to the first network corresponding to the first identification code type in the candidate networks, and calculate the target network quality index value and the index weight value of the target application scenario when the first network is available; if it is the second identification code type, initialize the current network according to the network configuration information included in the user identification code of the current network. After the initialization is completed, reconnect to the current network, and then calculate the target network quality index value and the index weight value of the target application scenario. After obtaining the target network quality index value and the index weight value, the candidate network quality index value of the candidate network can be determined, and then the candidate network quality score value of the candidate network can be determined by combining the target network quality index value and the index weight value. Then, the target candidate network can be determined according to the candidate network quality score value, and switch to the target candidate network. After switching to the target candidate network, the process can end.
