[0029] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In order to improve the technical problem that the network data channel switching speed of the main and auxiliary cards is slow due to untimely network monitoring in the prior art, thereby reducing the user experience. The present disclosure embodiment provides a data channel switching method, such as Figure 1 As shown, the method includes:

[0031] Step 101: Acquire multiple channel information of the current data channel, where the current data channel is the channel for current data communication between the host computer system and the server.

[0032] For the embodiments of the present disclosure, the host computer system may be a computer or a single-chip microcomputer that directly sends operating instructions, is responsible for business logic, and is used to provide a user operation interaction interface and display feedback data to the user, such as a computer, a mobile phone, a tablet, a panel, a touch screen, etc. In the embodiments of the present disclosure, the host computer system is taken as a mobile phone as an example to illustrate the technical solution in the present disclosure, but it does not constitute a specific limitation on the technical solution in the present disclosure.

[0033] In the disclosed embodiment, the host system can remotely access the connected server through the data channel between the host system and the server; the server can be used to provide an access interface so that a data channel can be established between the host system and the server. The host system and the server can communicate data through the data channel and transmit channel information to each other, wherein the channel information is information transmitted in the data channel, and may include picture information, audio information, signal data, etc., without specific limitation.

[0034] The execution subject of the embodiment of the present disclosure may be a baseband system, which is used to provide network access capabilities and data channels. The baseband system can establish a wireless network data channel with the network operator through the registration network, and obtain the network and bearer information of the network operator through the wireless network data channel, wherein the bearer information may include an IP address, which is not specifically limited. The network operator can access the server through a specific data channel. The tether system transmits the network and bearer information to the host computer system through the data channel between the host computer system and the host computer system. The host computer system receives the network and bearer information, completes the initialization, and transmits it to the host computer system through the control channel between the baseband system and the host computer system. The host computer system can connect to the network operator through the data channel between the baseband system and the wireless network data channel between the baseband system and the network operator, and further use the specific data channel of the network operator to connect to the server and interact with the data.

[0035] Step 102: Monitor multiple channel information based on the abnormal state detection strategy to obtain multiple monitoring results corresponding to the multiple channel information.

[0036] Among them, the abnormal state detection strategy includes at least one abnormal state detection strategy for network layer data transmission, and at least one abnormal state detection strategy for wireless network signal quality; the abnormal state detection strategy is used to determine whether the current data channel can transmit data normally, and the abnormal state detection strategy may include a variety of detection strategies for determining whether the communication state of the current data channel is an abnormal state, which is not limited to this. The abnormal state detection strategy may include but is not limited to the following four contents: data transmission delay, packet loss rate, success rate and wireless network signal measurement value. Exemplarily, the abnormal state detection strategy can be to monitor the positive feedback message ratio in the current data channel. If the positive feedback message ratio is less than the preset message ratio, it indicates that the current data channel transmission is abnormal, wherein the positive feedback message is an Ack (Acknowledgement) message. After receiving the data, the receiver replies to the positive feedback message to the sender to inform the sender that the data has been received. The preset message ratio is a ratio value that can be preset according to the actual situation. The abnormal state is a communication state in which the network signal strength is less than the preset strength threshold. The preset strength threshold is a preset network signal strength value that can ensure that the user does not experience freezes during use. For the embodiments of the present disclosure, by adopting abnormal status detection strategies in two dimensions (network layer (IP) data transmission and wireless network signal quality), multiple channel indicator data are monitored in parallel and comprehensive judgments are made, thereby achieving accurate monitoring of data channel network anomalies and realizing rapid switching of data channels.

[0037] Step 103: If a preset number of monitoring results among the multiple monitoring results are abnormal, it is determined that the communication state of the current data channel is an abnormal state.

[0038] For the embodiments of the present disclosure, when the network is monitored for the delay, packet loss rate, success rate and wireless network signal measurement value of data transmission, if there are a preset number of monitoring results that are abnormal, then the communication state of the current data channel is judged to be an abnormal state, wherein the preset number can be pre-set according to the actual situation, and can include but is not limited to 2, 3, 4, etc., and there is no limitation on this. If the communication state of the current data channel is judged to be an abnormal state according to the abnormal state detection strategy, that is, when the current data channel is detected in the process of transmitting channel information, when the current network signal strength is less than the preset strength threshold, it proves that the current network signal quality is reduced, in order to avoid the phenomenon of freezes when the user uses the mobile phone due to the slow network speed, the embodiments of the present disclosure can switch the current data channel to a backup data channel when it is detected that the network signal strength is less than the preset strength threshold, and specifically the process shown in step 103 can be executed to ensure the user's experience during use.

[0039] Step 104: If the communication state of the current data channel is an abnormal state, the current data channel is switched to a backup data channel, where the backup data channel is a channel for data communication to be established between the host computer system and the server.

[0040] For the disclosed embodiment, a separation system is mainly used to switch the current data channel. The separation system includes a baseband system (Modem) and a host system (Host). The baseband system provides network access capabilities and data channels, and the host system is responsible for business logic. This solution defines a dual-system collaboration solution when an exception occurs to achieve the purpose of fast switching, which can be applied to a variety of operating systems. This solution also takes into account the basic software layer division, the high cohesion and low coupling principle of module design, etc. Compared with the previous passive waiting for the wireless power distribution network to connect or disconnect, a solution for actively detecting and judging the exception is proposed, which greatly shortens the abnormality discovery time. In addition, this solution can achieve a millisecond-level data channel switching speed. The host computer can support dual-card dual-pass, which means that it can support two cards (main card and secondary card) to establish a data channel with the server at the same time. The data channel of the main card is selected by default to carry the network service. When the network signal quality of the main card is reduced, it will automatically switch to the backup data channel of the secondary card, reducing the phenomenon of freezes caused by slow network speed during use, and improving the user experience.

[0041] In summary, according to the data channel switching method provided by the present disclosure, compared with the current prior art, the present disclosure can realize the rapid switching of data channels and reduce the network jamming problem caused by the slow network speed. Specifically, multiple channel information of the current data channel can be obtained first, and the current data channel is the channel for data communication between the host system and the server; based on the abnormal state detection strategy, multiple channel information is monitored to obtain multiple monitoring results corresponding to the multiple channel information, and the abnormal state detection strategy includes at least one abnormal state detection strategy for network layer data transmission, and at least one abnormal state detection strategy for wireless network signal quality; a judgment module is used to judge that the communication state of the current data channel is abnormal if a preset number of monitoring results in multiple monitoring results are abnormal; if the communication state of the current data channel is abnormal, the current data channel is switched to a backup data channel, and the backup data channel is a channel for data communication to be established between the host system and the server. By applying the technical solution of the present disclosure, network monitoring of the current data channel is realized, and when it is determined that the communication state of the current data channel is abnormal, the current data channel is switched to the backup data channel. Compared with the previous method of passively waiting for the wireless power distribution network to connect or disconnect, the proposed solution of actively detecting and judging anomalies greatly shortens the anomaly discovery time and improves the user experience.

[0042] Further, as a refinement and extension of the above embodiment, in order to fully illustrate the specific implementation process of the method of the embodiment of the present disclosure, the embodiment of the present disclosure provides the following Figure 2 The specific method shown includes:

[0043] Step 201: Create multiple data channels between the host computer system and the server, and create a control channel between the baseband system and the host computer system.

[0044] Among them, multiple data channels are used for data communication between the host system and the server, and the multiple data channels may include a current data channel and at least one spare data channel. In the following embodiment steps in the present disclosure, the technical solution in the present disclosure is described by taking the multiple data channels including a current data channel and a spare data channel as an example, but it does not constitute a specific limitation. The control channel is used for the baseband system to send indication information to the host system, and the indication information may have a variety of indication meanings, such as indicating a successful network connection, indicating a network connection failure, etc., and there is no specific limitation on this.

[0045] For the embodiments of the present disclosure, Figure 3 As shown in the figure, the mainstream mobile terminal system architecture is divided into two parts: baseband system and host computer system. The baseband system includes: wireless unit, monitoring unit, control unit and communication unit; the wireless unit includes network signal analysis and wireless data bearer management; the monitoring unit is responsible for network quality and data channel transmission quality monitoring; the control unit is responsible for data channel switching control and communication with the host computer based on the control plane protocol; the communication unit is responsible for communication between the baseband system and the host computer system, which may include control channel and data channel. The host computer system includes: application unit, service unit, control unit and communication unit; the application unit is responsible for client business logic processing and communication with the remote server at the same time; the service unit is used to provide the system services required by the application layer unit, including command transmission and status reporting; the control unit is responsible for communication with the baseband system and internal control of the host computer; the communication unit is responsible for communication between the baseband system and the host computer system, including control channel and data channel.

[0046] In the embodiment of the present disclosure, when creating multiple data channels between the host computer system and the server, the baseband system can complete initialization after startup, use the wireless unit of the baseband system to register the network communication functions of SIM1 and SIM2 cards, and establish wireless network data channels between SIM1 and SIM2 cards and their respective network operators. The baseband system transmits channel information such as network information and bearer information carried in the wireless network data channel to the host computer system through the control channel, and establishes a data channel with the host computer system. The host computer system can communicate data with the server through the data channel between the baseband system and the wireless network data channel between the baseband system and the network operator, wherein the network operator can access the server through a specific data channel.

[0047] Step 202: Acquire multiple channel information of the current data channel, where the current data channel is the channel for current data communication between the host computer system and the server.

[0048] For the implementation process of the embodiment of the present disclosure, please refer to the relevant description in step 101 of the embodiment, which will not be repeated here.

[0049] Step 203: Monitor multiple channel information based on abnormal state detection strategies to obtain multiple monitoring results corresponding to the multiple channel information. The abnormal state detection strategies include at least one abnormal state detection strategy for network layer data transmission and at least one abnormal state detection strategy for wireless network signal quality.

[0050] For the embodiments of the present disclosure, the monitoring unit of the baseband system is mainly used to monitor whether the current data channel meets the abnormal state detection strategy. In a specific application scenario, the monitoring unit can monitor the delivery time of the network detection information sent to the operator server by creating a first daemon thread. If the delivery time exceeds the preset delivery time period of the network detection information, it indicates that the current data channel transmission is abnormal. Among them, network detection is a function provided by the system. The network detection command can be used to check whether the network is unobstructed or the network connection speed. After using the network detection command, the current network status can be understood through the delivery time of the return information of the command. The first daemon thread is a thread used to monitor the delivery time of the network detection information.

[0051] In a specific application scenario, the monitoring unit can monitor the loss ratio of the current data channel in the process of transmitting channel information by creating a second daemon thread, and can monitor the negative feedback message ratio in the current data channel. If the negative feedback message ratio is greater than the preset message ratio, it indicates that the current data channel transmission is abnormal, wherein the negative feedback message is a NACK message (Negative Acknowledgement, NACK). When the receiver does not receive the data, it sends a negative feedback message to the sender to inform the sender that the data has not been received. The second daemon thread is a thread used to monitor the loss ratio of the current data channel in the process of transmitting channel information.

[0052] In a specific application scenario, the monitoring unit can monitor the transmission success rate of the current data channel during the transmission of channel information by creating a third daemon thread. If the transmission success rate is less than the preset success rate, it indicates that the current data channel transmission is abnormal. The preset success rate is a success value that can be pre-set according to actual conditions. The third daemon thread is a thread that can be used to monitor the transmission success rate of the current data channel during the transmission of channel information.

[0053] In a specific application scenario, the monitoring unit can monitor the periodic wireless network signal measurement value by creating a fourth daemon thread, wherein the fourth daemon thread is a thread for monitoring the wireless network signal measurement value. By reading the reference signal received power, reference signal received quality, received signal strength index and signal to interference plus noise ratio of the wireless network signal measurement value in the channel information, and comparing with the preset signal reference value, if at least one signal value is less than the preset signal reference value, it indicates that the current data channel transmission is abnormal. Among them, the reference signal received power is the (Reference Signal Received Power, RSRP) signal value, the reference signal received quality is the (Reference Signal Receiving Quality, RSRQ) signal value, the received signal strength index is the (Received Signal Strength Indicator, RSSI) signal value, the signal to interference plus noise ratio is the (Signal to Interference plus Noise Ratio, SINR) signal value, and the preset signal reference value is a reference value of each signal value that can be set in advance according to actual conditions, and there is no specific restriction on this.

[0054] For the embodiments of the present disclosure, multiple channel information is monitored based on the abnormal state detection strategy to obtain multiple monitoring results corresponding to the multiple channel information. The specific implementation process can be described as: create multiple daemon threads corresponding to the abnormal state detection strategy respectively, monitor the multiple channel information through the multiple daemon threads, and obtain multiple monitoring results corresponding to the multiple channel information. Among them, the multiple daemon threads may include a first daemon thread, a second daemon thread, a third daemon thread and a fourth daemon thread, or may also include other daemon threads for detecting channel information, which are not specifically limited here. When the channel information includes the delivery time of the network detection information, the first daemon thread can be used to monitor whether the delivery time exceeds the preset delivery time period of the network detection information to obtain the first monitoring result. The network detection information is used to characterize the transmission delay of the channel information during the transmission process; if the delivery time exceeds the preset delivery time period of the network detection information, the first monitoring result is abnormal; if the delivery time does not exceed the preset delivery time period of the network detection information, the first monitoring result is normal. When the channel information includes the negative feedback message ratio, the second daemon thread can be used to monitor whether the negative feedback message ratio is greater than the preset message ratio to obtain the second monitoring result, and the negative feedback message ratio is used to characterize the loss ratio of the channel information during the transmission process; if the negative feedback message ratio is greater than the preset message ratio, the second monitoring result is abnormal; if the negative feedback message ratio is less than or equal to the preset message ratio, the second monitoring result is normal. When the channel information includes the transmission success rate of the current data channel, the third daemon thread can be used to monitor whether the transmission success rate is less than the preset success rate to obtain the third monitoring result, and the transmission success rate is used to characterize the success ratio of the channel information during the transmission process; if the transmission success rate is less than the preset success rate, the third monitoring result is abnormal; if the transmission success rate is greater than or equal to the preset success rate, the third monitoring result is normal. When the channel information includes a wireless network signal measurement value, the fourth daemon thread can be used to monitor whether the wireless network signal measurement value is less than the corresponding preset signal reference value to obtain a fourth monitoring result. The wireless network signal measurement value is used to characterize the wireless network signal quality of the current data channel. The wireless network signal measurement value includes at least one of the following: reference signal receiving power, reference signal receiving quality, received signal strength index, and signal to interference plus noise ratio; if the wireless network signal measurement value is less than the corresponding preset signal reference value, the fourth monitoring result is abnormal; if the wireless network signal measurement value is greater than or equal to the corresponding preset signal reference value, the fourth monitoring result is normal.

[0055] For the embodiments of the present disclosure, when monitoring multiple channel information based on the abnormal state detection strategy, by creating a daemon thread corresponding to the abnormal state detection strategy and using the daemon thread to monitor different channel information in parallel, automatic monitoring of data channel abnormalities can be achieved, thereby improving the monitoring efficiency and accuracy of abnormal states.

[0056] This disclosure defines a dual-system collaboration solution when an abnormality occurs to achieve the purpose of fast switching, which can be applied to a variety of operating systems. It also introduces two dimensions to monitor abnormal events, network layer (IP) data abnormalities and wireless signal quality abnormalities, and monitors multiple indicator data in parallel for comprehensive judgment, including: throughput, latency, packet loss rate, RSRP / RSRQ / RSRI / SINR, etc., thereby shortening the abnormality discovery time and reducing the misjudgment rate.

[0057] Step 204: If a preset number of monitoring results among the multiple monitoring results are abnormal, it is determined that the communication state of the current data channel is an abnormal state.

[0058] For the disclosed embodiment, as a possible implementation method, when the monitoring result of any daemon thread is abnormal, other monitoring results monitored by other daemon threads can be obtained. If at least one monitoring result among the other monitoring results is abnormal, the communication state of the current data channel can be judged to be abnormal. That is, if at least two monitoring results among the multiple monitoring results corresponding to all daemon threads are abnormal, the communication state of the current data channel is judged to be abnormal, which proves that the current network signal quality is low.

[0059] Step 205: Send instruction information to the host computer system through the control channel.

[0060] For the embodiment of the present disclosure, when the monitoring unit of the baseband system confirms that the current data channel is in an abnormal state, such as Figure 4 As shown, the monitoring unit of the baseband system sends an abnormal signal to the control unit of the baseband system to indicate that the current data channel is in an abnormal state. After receiving the abnormal signal, the control unit sends indication information to the communication unit of the baseband system to instruct the host computer system to disconnect the data connection with the server. After receiving the indication information, the communication unit of the baseband system sends the indication information to the communication unit of the host computer system. The communication unit of the host computer system sends the received indication information to the control unit of the host computer system. The control unit of the host computer system controls the application unit of the host computer system to disconnect the data connection with the server, and sends a disconnection signal to the service unit, and uses the service unit to notify the application unit that the data connection has been disconnected.

[0061] Step 206: If the communication state of the current data channel is an abnormal state, the current data channel is switched to a backup data channel, where the backup data channel is a channel for data communication to be established between the host system and the server.

[0062] For the embodiments of the present disclosure, Figure 4As shown, after the current data channel is switched to the backup data channel, the control unit of the baseband system controls the communication unit of the baseband system to send a reconstruction success signal to the communication unit of the host system through the control channel, which is used to indicate that the current data channel is the backup data channel. The communication unit of the host system sends a reconstruction success signal to the control unit of the host system. After receiving the reconstruction success signal, the control unit of the host system sends the reconstruction success signal to the service unit of the host system, and uses the service unit to notify the application unit to re-establish the connection with the server.

[0063] In summary, according to the data channel switching method provided by the present disclosure, compared with the current prior art, the present disclosure can realize the rapid switching of data channels and reduce the network jamming problem caused by the slow network speed. Specifically, multiple channel information of the current data channel can be obtained first, and the current data channel is the channel for data communication between the host system and the server; based on the abnormal state detection strategy, multiple channel information is monitored to obtain multiple monitoring results corresponding to the multiple channel information, and the abnormal state detection strategy includes at least one abnormal state detection strategy for network layer data transmission, and at least one abnormal state detection strategy for wireless network signal quality; a judgment module is used to judge that the communication state of the current data channel is abnormal if a preset number of monitoring results in multiple monitoring results are abnormal; if the communication state of the current data channel is abnormal, the current data channel is switched to a backup data channel, and the backup data channel is a channel for data communication to be established between the host system and the server. By applying the technical solution of the present disclosure, network monitoring of the current data channel is realized, and when it is determined that the communication state of the current data channel is abnormal, the current data channel is switched to the backup data channel. Compared with the previous method of passively waiting for the wireless power distribution network to connect or disconnect, the proposed solution of actively detecting and judging anomalies greatly shortens the anomaly discovery time and improves the user experience.

[0064] Based on the above Figure 1 and Figure 2 The specific implementation of the method shown in the embodiment provides a data channel switching device, such as Figure 5 As shown, the device includes: an acquisition module 31, a monitoring module 32, a judgment module 33, and a switching module 34;

[0065] The acquisition module 31 can be used to obtain multiple channel information of the current data channel, where the current data channel is the channel for current data communication between the host computer system and the server;

[0066] A monitoring module 32, which can be used to monitor multiple channel information based on an abnormal state detection strategy to obtain multiple monitoring results corresponding to the multiple channel information, wherein the abnormal state detection strategy includes at least one abnormal state detection strategy for network layer data transmission and at least one abnormal state detection strategy for wireless network signal quality;

[0067] A judgment module 33, configured to judge that the communication state of the current data channel is an abnormal state if a preset number of monitoring results among the multiple monitoring results are abnormal;
