Description

Network connection method, electronic device, and computer-readable storage medium

Technical Field

The present application relates to the field of communications, and in particular, to a network connection method, an electronic device, and a computer readable storage medium.

Background

After the electronic equipment and the other terminal which are logged in the same account are paired, far-field communication can be carried out through the server, so that notification information on the electronic equipment is synchronized to the other terminal. For example, when the mobile phone is far away from the watch, the mobile phone is disconnected from the watch by bluetooth, far-field communication can still be performed, and the mobile phone can synchronize the notification message to the watch in real time through the far-field communication, so that a user can view the notification message in real time and reply quickly. In the prior art, in the context of far-field communications, communications between an electronic device and a server are implemented based on the transmission control protocol (TCP, transmission Control Protocol). TCP has a weak capability of reflecting link abnormality, and whether link abnormality occurs needs to be determined according to data transmission conditions between the electronic device and the server, so that network change of an application layer cannot be perceived rapidly based on TCP. When the network is in a connected state but the network is not available (such as abnormal router, width arrears, hot spot closing, etc.), the electronic device still sends a notification message to the server, so that the notification message cannot be sent to another terminal through the server, and thus the instantaneity of communication cannot be guaranteed.

The network connection system provided by the embodiment of the application is described below by taking an example that one of the electronic devices is a mobile phone and the other electronic device is a watch.

As shown in fig. 2, the mobile phone and the watch are devices for establishing trust relationship. The mobile phone and the watch log in the same user account to perform trusted authentication, so that a trust relationship is established, and a trust ring is formed. Under the condition that the mobile phone and the watch are connected with each other, when the mobile phone receives the notification message, the mobile phone sends the notification message to the watch through the server, so that the synchronization of the notification message is realized. The watch can realize communication connection with the server by opening the eSIM.

Specifically, the server is a cluster server, and the server is divided into an account cloud, a trust ring cloud, a device cloud and a far-field cloud according to the function of the server. The mobile phone and the watch log in the account cloud through the user account respectively, when authentication is needed, a first account authentication module of the mobile phone sends the user account of the mobile phone to the trust ring cloud, a second account authentication module of the watch sends the user account of the watch to the trust ring cloud, the trust ring cloud obtains account information of the mobile phone and the watch from the account cloud, the same account authentication is carried out, and authentication results are sent to the first account authentication module and the second account authentication module respectively. And under the condition that the authentication result is that the authentication is passed, the mobile phone and the watch establish a trust relationship through the trust ring cloud to form a trust ring.

The mobile phone and the watch can also carry out double-end authentication through the device cloud when in first communication. For example, the mobile phone sends the authentication information to the equipment cloud through the first connection module, the watch sends the authentication information to the equipment cloud through the second connection module, the equipment cloud verifies the received authentication information, the authentication results are respectively sent to the first connection module and the second connection module, the first connection module sends the authentication information to the first account authentication module, the second connection module sends the authentication information to the second account authentication module, and the account authentication module can display the authentication results on a display interface of the mobile phone/the watch. The first connection module and the second connection module are modules for realizing information sharing among devices, and include a module located in an application framework layer and a module located in a HAL, for example, a logic link may be used.

The first transmission module on the mobile phone and the second transmission module on the watch can also perform double-end authentication through far-field cloud before sending the notification message. For example, the first transmission module and the second transmission module respectively send authentication information of the mobile phone and the watch to a far-field cloud, the far-field cloud authenticates the authentication information, authentication results are respectively sent to the first transmission module and the second transmission module, the first transmission module sends the authentication results to the first account authentication module, and the second transmission module sends the authentication results to the second account authentication module. The first transmission module and the second transmission module are used for realizing data transmission between the mobile phone and the watch, and include a module located in an application framework layer and a module located in a HAL, for example, a magic ring.

After authentication is completed, the mobile phone can synchronize the notification message to the watch through the server.

Specifically, the notification message is a notification message of an application program, for example, may be a short message of a short message application program, weather reminding information of a weather application program, schedule reminding information of a schedule application program, time information of an alarm clock application program, motion information of a motion health application program, or the like, or may be a notification message sent to a preset functional module on the electronic device by a third party server. The notification message can be displayed on the mobile phone display interface in the form of a card according to the setting information of the user, and can also be displayed on a notification bar.

A message notification module (which can be a system application) on the mobile phone monitors notification messages of the application program, and when the application program is determined to generate new notification messages, the notification messages are transmitted to a first transmission module through a first connection module. Meanwhile, the first connection module pulls up the first transmission module, the first transmission module sends the notification message to the far-field cloud through the first communication module (such as libwebsocket), the far-field cloud determines the identification of the watch establishing trust relationship with the mobile phone according to the identification (such as comID) of the mobile phone, and the notification message is sent to the second transmission module on the watch through the second communication module on the watch according to the identification of the watch. The second transmission module sends the notification message to the message receiving module through the second connection module on the watch. The message receiving module may include one or more applications on the watch, such as sports health, weather, etc., or other functional modules on the watch for receiving messages. The second connection module may send the notification message to the corresponding application according to the identifier corresponding to the notification message. A message display module (such as a system UI) on the watch displays the notification message received by the message receiving module on a display interface of the watch, so that synchronization of the notification message is realized.

The control channel between the first transmission module and the second transmission module comprises an end cloud control channel between the first transmission module and the far-field cloud and an end cloud control channel between the second transmission module and the far-field cloud. The end cloud control channel is a long connection established through websocket. The websocket long connection adopts an open-source websocket library, and the websocket bottom layer is based on TCP. The communication mode based on TCP is that one of the two ends of communication sends detection information to the opposite end according to a set interval, and whether the two ends normally communicate is determined according to whether the opposite end replies a confirmation character (Acknowledge character, ACK), and further whether the network connection is abnormal is determined. Therefore, the communication mode based on TCP cannot quickly sense network abnormality, has weak capability of reflecting link abnormality, and cannot provide excessive abnormality processing details for the upper application program. For example, when a mobile phone is in a network connection state and a network becomes unavailable from available, information determined based on TCP cannot quickly perceive a network change. When the network is not available, the mobile phone side can still generate notification messages according to the condition that the network is available. Because the network is not available, the notification message cannot be sent to the watch through the server, and in the case that the network is not available and becomes available, the mobile phone cannot quickly sense the network change information, and still cannot disconnect the old connection from the server and establish a new connection, so that the notification message cannot be sent to the watch. Thus, determining network information based on TCP cannot guarantee immediate synchronization of notification messages.

Fig. 3 is a flowchart of a method for TCP-based network connection according to an embodiment of the application.

As shown in fig. 3, the mobile phone and the watch establish an end-to-end control channel through the server, and the mobile phone and the server communicate through the end-to-cloud control channel. Under the conditions of network disconnection and network switching, the mobile phone can receive LWS_CALLBACK_CLIENT_CLOSED information called back by the first communication module. And then, marking reconnection flag bits by the mobile phone, wherein the numerical value of the reconnection flag bits represents reconnection times. The mobile phone determines whether the current reconnection times reach the set reconnection times (for example, 2 times) according to the value of the reconnection flag bit. And if the set reconnection times are reached, releasing the cloud control channel by the mobile phone. If the set reconnection times are not reached, further determining whether the reconnection condition is satisfied, wherein whether the reconnection condition is satisfied can be determined according to whether the reconnection time interval is reached and whether the total reconnection duration is reached. And if the reconnection condition is met, reconnecting again, and if the reconnection condition is not met, releasing the control connection channel by the mobile phone. Under the condition that the network resumes the mobile phone networking, the mobile phone receives client_APPEND_ HANDSHAKE _HEADER information called back by the first communication module, and then the mobile phone is reconnected with the server to establish an end cloud control channel, so that the mobile phone and the watch establish the end cloud control channel through the server.

Under the condition that the network connection of the mobile phone is unavailable, the mobile phone cannot sense in time, the server side does not sense either, and the mobile phone can only determine that the network is abnormal when the server or the mobile phone fails to send detection information or heartbeat keep-alive packets to the opposite terminal or when the server or the mobile phone fails to send notification messages to the opposite terminal, so that the mobile phone can release the cloud control channel of the end.

Fig. 4 is a timing diagram of a method for TCP-based network connection according to an embodiment of the present application.

As shown in fig. 4, the mobile phone includes a first connection module, a first transmission module and a first communication module, the server includes a far-field cloud, and the watch includes a second transmission module and a second connection module. The first connection module is used for receiving the notification message of the mobile phone and sending the notification message to the first transmission module. The first transmission module is configured to establish a communication connection with the server through the first communication module and send a notification message to the server, and the first communication module may be a libwebsocket. The second transmission module establishes a control channel with the first transmission module through the server, and is used for receiving the notification message sent by the first transmission module through the server. The second connection module is used for sending the notification message received by the second transmission module to the message display module on the watch, so that the notification message is displayed on the watch.

The first transmission module monitors the network thread of the first communication module, determines whether the mobile phone is connected with a network, and establishes a control channel through the server to perform data transmission under the condition that the mobile phone is connected with the network. In the case of a network outage, the first transmission module receives lws_call_client_closed information called back by the first communication module, determines that the network is disconnected according to the received information, sends an outage instruction (for example, may be an sm_event_device_group_release instruction) to the first communication module, and disconnects the connection with the server according to the outage reconnection instruction.

After the first transmission module sends the network disconnection instruction to the first communication module, if the notification message sent by the first connection module is received, the first transmission module caches the notification message. And after the first transmission module sends the disconnected reconnection instruction to the first communication module, marking reconnection flag bits, wherein the initial value of the reconnection flag bits is the set reconnection times. If the current reconnection times are not up to the set reconnection times according to the value of the reconnection flag bit, the first transmission module subtracts 1 from the value of the reconnection flag bit to update the value of the reconnection flag bit. And then, the first transmission module determines whether the reconnection condition is met, and if the reconnection condition is met, the first transmission module instructs the first communication module to execute reconnection action. The first communication module enters a connect state machine according to the indication information of the first transmission module, reestablishes websocket connection, and starts a timer, wherein the duration of the timer is retransmission interval. And when the duration of the timer is up, the first communication module sends a reconnection request to the server. If reconnection fails, the first communication module sends CALLBACK information of LWS_CALLBACK_CLIENT_CONNECTION_ERROR to the first transmission module, and the first transmission module disconnects websocket according to the CALLBACK information. Under the condition that the current reconnection times are not up to the set reconnection times according to the value of the reconnection flag bit, subtracting 1 from the value of the reconnection flag bit, and then determining whether the reconnection condition is met. If the reconnection condition is met, the first communication module enters a connect state machine again according to the indication of the first transmission module, reestablishes websocket connection, starts a timer, and sends a reconnection request to the server when the duration of the timer is reached.

And the first transmission module determines that the set reconnection times are reached according to the value of the reconnection flag bit, and indicates the first communication module to disconnect the cloud connection channel under the condition that reconnection failure information returned by the first communication module is received. The first communication module returns information of the release channel, for example, onCtrlChannelStatusUpdated (status= -202), after disconnecting the end cloud connection channel. If there is a cache message, the first communication module returns a message of failed transmission, for example, onCtrlMsgSendUpdated (status= -1000). The first transmission module transmits the information of the release channel returned by the first communication module and the information of the transmission failure to the first connection module.

In the reconnection process, if the network is restored, the mobile phone is connected, the first transmission module receives LWS_CALLBACK_CLIENT_APPEND_ HANDSHAKE _HEADER information called back by the first communication module, the first transmission module updates the value of the reconnection flag bit, and under the condition that the reconnection condition is confirmed to be met, the first transmission module enters a connect state machine, the websocket connection is rebuilt, and the duration of a timer is reached, the first communication module sends a reconnection request to the server. The server returns configuration information such as heartbeat time and the like to the first communication module according to the reconnection request, and the first communication module sends the configuration information to the first transmission module, so that the first transmission module and the server establish heartbeat connection, and further an end cloud control channel is established. And then, the first transmission module and the second transmission module establish an end-to-end control channel through the server. The first transmission module sends the identification of the mobile phone and the notification message to the server under the condition that the cached notification message exists, the server sends the notification message to the second transmission module at the watch side according to the identification of the mobile phone, the second transmission module sends the notification message to the second connection module, and the second connection module sends the notification message to the display module on the watch, so that the notification message is displayed on the display interface of the watch. And under the condition that the message is successfully sent, the first transmission module receives the message returned by the server and the message is successfully sent. The first transmission module returns the message which is successfully sent to the first connection module.

The first communication module may initiate a reconnection request to the server in case of a network disconnection based on the TCP protocol. However, in the case that the network is connected and the network is unavailable, the first communication module cannot sense in time, and when the first transmission module receives the notification message, the notification message is still sent to the server, so that the notification message cannot be sent to the watch, and the instantaneity of the notification message received by the watch is affected.

In order to solve the above-mentioned problems, an embodiment of the present application provides a network connection method, in which a mobile phone determines a network connection state of the mobile phone through a network quality parameter monitored locally, and if the network connection state is a connected network and a network is unavailable state, the mobile phone sends a reconnection request to a server through a first communication module. The network quality parameter is used for representing the WIFI connection state, or the network quality parameter is the network speed of a network connected with the mobile phone, and can reflect the communication capability of the mobile phone. Compared with the method for determining the network connection state through the data transmission condition between the two terminals based on the TCP protocol, the method for determining the network connection state can determine the network connection state more quickly by locally monitoring the network quality parameters without waiting for the response information of the server, so that a reconnection request can be sent to the server quickly when the network is unavailable, communication connection can be established with the server again, and the instantaneity of sending the notification message to the server is improved.

In an embodiment, the network quality parameter is used for characterizing a WIFI connection state, and the mobile phone determines the network connection state by monitoring the WIFI connection state detected by the WIFI tracker. The WIFI connection state comprises a WIFI disconnection state, a WIFI connection and availability state and a WIFI connection and unavailable state. The WIFI tracker is located application program framework layer and is used for receiving the WIFI connection state broadcasted by the WIFI module.

Specifically, the WIFI module of the mobile phone determines a network quality parameter for characterizing a WIFI connection state according to a WIFI quality (e.g., a WIFI signal strength). The WifiManager_STATE_CHANGED_ACTION in the WIFI module broadcasts network info information, wherein the network info information carries network quality parameters for representing the WIFI connection STATE. The WIFI tracker receives network info information broadcast by the WifiManager, NETWORK_STATE_CHANGED_ACTION, obtains network quality parameters according to the broadcast information, and further determines the WIFI connection STATE.

In an embodiment, after determining the WIFI connection state, the WIFI tracker sends the WIFI connection state to the first transmission module, and the first transmission module determines a network connection state according to the WIFI connection state, where the network connection state is consistent with the WIFI connection state. When the network connection state is a connected network and the network is unavailable, the first transmission module indicates the first communication module to send a reconnection request to the server, so that the network connection state can be determined without waiting for a response of the server, and the connection can be quickly reestablished with the server under the condition that the network is unavailable, thereby improving the instantaneity of message synchronization of the mobile phone and the watch.

The WIFI tracker can also display the current WIFI connection state on the display interface according to user operation. Illustratively, in the case where the mobile phone detects that the user opens the network setting information, a network setting page as shown in fig. 5 is displayed on the display interface. The network equipment page displays the opening option of the WLAN, the setting option of the WLAN, the name of the WLAN to which the mobile phone is currently connected and the connection state of the WLAN. For example, the name of the WIFI network currently connected to the mobile phone is ABC, and if the WIFI connection state obtained by the WIFI tracker is a connected network and the network is unavailable, information that the WIFI is connected (can not be connected to the internet) is displayed on the display interface.

In the case that the mobile phone determines the network connection state by monitoring the WIFI tracker, a specific flow of the network connection method is shown in fig. 6.

The mobile phone and the watch establish an end-to-end control channel through the server (S61), and the mobile phone and the server communicate through an end-to-cloud connection channel. The mobile phone monitors the WIFI connection state detected by the WIFI tracker (S62). In the case of network disconnection and network switching (S63), the mobile phone receives lws_call_client_closed information called back by the first communication module (S64), and determines to perform network disconnection reconnection. Meanwhile, the mobile phone can determine the conditions of network disconnection and network switching according to the WIFI connection state detected by the WIFI tracker, and can also determine the conditions that the connected network is unavailable. In case of network disconnection, network handover, connected network and network unavailability (S65), the handset determines to perform a network disconnection reconnection.

After determining that the network is disconnected and reconnected, the mobile phone marks a reconnection flag bit (S66), and the value of the reconnection flag bit represents the reconnection times. The mobile phone determines whether the set reconnection times are reached according to the value of the reconnection flag bit (S67). If the set reconnection times are reached, the mobile phone releases the end cloud control channel (S68). If the set number of reconnections is not reached, the mobile phone further determines whether the reconnection condition is satisfied (S69), where whether the reconnection condition is satisfied may be determined according to whether a reconnection time interval (for example, may be 3S) is reached, and whether the total reconnection duration is reached. If the reconnection condition is satisfied, reconnection is performed (S610), and if the reconnection condition is not satisfied, the handset releases the end cloud control channel (S68).

If the network is disconnected, if the network is restored, the mobile phone is networked (S611), the mobile phone receives client_application_ HANDSHAKE _header information called back by the first communication module (S612), and then the mobile phone is reconnected with the server to establish an end cloud control channel (S613). If the mobile phone determines that the network connection state is the connected network and the network is available according to the WIFI connection state detected by the WIFI tracker (S614), the mobile phone and the server are reconnected to establish the end cloud control channel (S613). Under the condition that the mobile phone and the server establish an end cloud control channel, the mobile phone and the watch establish the end cloud control channel through the server.

As shown in fig. 7, the timing diagram of the above network connection method is different from the TCP-based network connection method in that the first transmission module further obtains a WIFI connection state from the WIFI tracker, and initiates a reconnection request to the server according to the WIFI connection state.

Specifically, the mobile phone comprises a first connection module, a WIFI tracker, a first transmission module and a first communication module, and the watch comprises a second transmission module and a second connection module.

The first connection module instructs the first transmission module to initiate far-field communication according to an instruction to establish communication connection with the wristwatch. In the far-field communication process, the first transmission module monitors the WIFI tracker from an upper layer, and when the network connection state is determined to be the connected network and the network is available according to the WIFI connection state detected by the WIFI tracker, the first transmission module calls the first communication module to establish an end cloud connection channel with the server, so that the first transmission module and the second transmission module establish an end control channel through the server.

When the source of the WIFI network connected to the mobile phone is disconnected, a WIFI STATE machine (WIFI STATE machine) of the WIFI module indicates that the WIFI manager. And the WIFI tracker receives the broadcast information and determines the WIFI connection state according to the broadcast information.

The first transmission module monitors the WIFI tracker to obtain a WIFI connection state. For example, if the network quality parameter for characterizing the WIFI connection status includes network info. GetDetailedState () =DetailedState. CONNECTED, wificonTignomonworutil. AP_NO_INTERNET_ACCESS, wificonTignomonwortil. PORTAL_AP_UNAUTHORIZED, the first transmission module determines that the network connection status is connected to the network and the network is unavailable, inserts a high priority processing task (for example, ctrlChannelProcWsReconnect) from CtrCreateUsers task of an upper layer (frame layer), the high priority task is used to instruct the first communication module to disconnect the network. The first communication module disconnects the connection with the server according to the network disconnection indication.

After the first transmission module sends the network disconnection instruction to the first communication module, if the notification message sent by the first connection module is received, the first transmission module caches the notification message. The first connection module may send the notification message to the first transmission module by calling SendCtrlMsg. The first transmission module marks the reconnection flag bit after sending a disconnection instruction to the first communication module. If the current reconnection times are not up to the set reconnection times according to the value of the reconnection flag bit, the first transmission module subtracts 1 from the value of the reconnection flag bit to update the value of the reconnection flag bit. And then, the first transmission module determines whether the reconnection condition is met, and if the reconnection condition is met, the first transmission module instructs the first communication module to execute reconnection action. The first communication module enters a connect state machine according to the indication information of the first transmission module, reestablishes websocket connection, and starts a timer, wherein the duration of the timer is retransmission interval. And when the duration of the timer is up, the first communication module sends a reconnection request to the server. If reconnection fails, the first communication module sends CALLBACK information of LWS_CALLBACK_CLIENT_CONNECTION_ERROR to the first transmission module, and the first transmission module disconnects websocket CONNECTION according to the CALLBACK information. Under the condition that the current reconnection times are not up to the set reconnection times according to the value of the reconnection flag bit, subtracting 1 from the value of the reconnection flag bit, and then determining whether the reconnection condition is met. If the reconnection condition is met, the first communication module enters a connect state machine again according to the indication of the first transmission module, reestablishes websocket connection, starts a timer, and sends a reconnection request to the server when the duration of the timer is reached.

The first transmission module indicates the first communication module to break the cloud control channel under the condition that the first transmission module determines that the set reconnection times are reached according to the value of the reconnection flag bit and receives reconnection failure information returned by the first communication module. And the first communication module returns information of the release channel after disconnecting the end cloud connection channel. If the information cached in the first transmission module is not sent successfully, the first communication module returns information of failed sending to the first transmission module.

In the reconnection process, if the WIFI connection state in the broadcast information received by the WIFI tracker is networkinfo. If the reconnection condition is satisfied, the first transmission module instructs the first communication module to execute the reconnection operation. The first communication module enters a connect state machine according to the indication information of the first transmission module, reestablishes websocket connection, and starts a timer, wherein the duration of the timer is retransmission interval. When the duration of the timer is reached, the first communication module sends a reconnection request to the server, wherein the reconnection request comprises authentication information of the mobile phone side. The server returns configuration information such as authentication information and heartbeat time of the server side to the first communication module according to the reconnection request, and the first communication module sends the configuration information to the first transmission module, so that the first transmission module and the server establish heartbeat connection, and the end cloud connection channel is successfully established. And then, the mobile phone sends a handshake message to the watch through the server, and establishes an end control channel with the watch after receiving the watch handshake ACK. The first transmission module sends the cached notification message to the second transmission module through the end control channel, and the second transmission module returns the successful notification message receiving information to the first connection module after receiving the notification message, wherein the successful notification message receiving information can be OnReceiveCtrlMsg (status=0).

It can be understood that, according to the WIFI connection status obtained from the WIFI tracker, the first transmission module may determine whether the network connection status of the mobile phone is a disconnected network status, in addition to determining that the network connection status is a connected network and the network is unavailable and determining that the network is restored. For example, when the WIFI connection state is the WIFI disconnection state, and when the mobile phone determines that the network connection state is the disconnection state, the mobile phone also initiates a reconnection request to the server.

The first transmission module monitors the WIFI connection state of the WIFI tracker and monitors the network thread of the first communication module. And the first transmission module is used for reconnecting with the server through the first communication module under the condition of determining that the network is disconnected according to the monitoring result of the network thread, and establishing an end cloud control channel with the server through the first communication module under the condition of recovering the network. The process that the first transmission module is reconnected with the server through the first communication module, and the process that the end cloud control channel is established with the server through the first communication module is consistent with the process of the network connection method based on TCP, and is not repeated here.

The WIFI tracker can directly reflect the real-time WIFI connection condition of the mobile phone according to the WIFI connection state determined by the broadcast information of the WIFI module, further can reflect the communication capability of the mobile phone, and indicates that the network of the mobile phone is abnormal when the WIFI connection state is the connected WIFI and the WIFI is unavailable, notification information of the mobile phone cannot be sent to the opposite-end watch through the server, so that message synchronization is realized, the mobile phone sends a reconnection request to the server, new connection can be quickly established between the mobile phone and the server, and the instantaneity of the message synchronization is improved.

In another embodiment, the network quality parameter is a network speed of a network connected to the mobile phone, and the mobile phone determines the network connection state through monitoring the network speed detected by a system user interface (SystemUI, for system application). If the network speed is smaller than a preset speed (for example, 1 k/s), determining that the network connection state of the mobile phone is a connected network and network unavailable state, and if the network speed is larger than or equal to the preset speed, determining that the network connection state of the mobile phone is a connected network and network available state.

The mobile phone can also display the network speed detected by the system user interface on the display interface according to the user setting information, for example, the network speed can be displayed in a status bar of the display interface.

In an embodiment, the first transmission module obtains the network speed through the monitoring system user interface, and when the network connection state of the mobile phone is determined to be the connected network and the network is unavailable according to the network speed, instructs the first communication module to send a reconnection request to the server, so that connection can be quickly reestablished with the server under the condition that the network is unavailable, and the instantaneity of message synchronization of the mobile phone and the watch is improved.

Specifically, as shown in fig. 8, the mobile phone and the watch establish an end-to-end control channel through the server (S81), and the mobile phone communicates with the server through an end-to-cloud connection channel. The system user interface calls a refresh Speed module (a module for monitoring the Network Speed) according to a set interval to acquire the Network Speed, the Network Speed is updated in the Network Speed manager Ex.java, the mobile phone monitors the textValue in the Network Speed manager Ex.java to acquire the Network Speed (S82), and the textValue is used for storing the value of the Network Speed monitored by the system user interface. After obtaining the network speed, the mobile phone judges whether the network speed is smaller than a preset speed (S83). If the network speed is greater than or equal to the preset speed, the mobile phone determines that the network connection state is the connected network and the network is available, and continues to monitor the network speed obtained by the system user interface. If the network speed is smaller than the preset speed, the mobile phone determines that the network connection state is the connected network and the network is unavailable, and further determines to disconnect and reconnect the network. Meanwhile, the mobile phone receives LWS_CALLBACK_CLIENT_CLOSED information called back by the first communication module (S85) under the conditions of network disconnection and network switching based on the bottom TCP protocol (S84), and determines to disconnect and reconnect.

After determining that the network is disconnected and reconnected, the mobile phone marks a reconnection flag bit and a reconnection status bit (S86), wherein the value of the reconnection flag bit indicates the reconnection times, and the value of the reconnection status bit indicates whether reconnection is in progress or not. If the handset is reconnecting, the handset sets the value of the reconnection status bit to a preset value (e.g., 1 or Y, etc.). When the mobile phone is reconnected next time, whether the mobile phone is in a state of initiating a reconnection request to the server or not can be determined according to the reconnection status bit. The network speed information received by the system user interface can be information of any network connected with the mobile phone, for example, the system user interface monitors the network speed information of a module such as TelephonyIntents, connectivityManager, wifiManager of the mobile phone, and can obtain the network speed information of other networks such as 4G, 5G and the like besides the network speed of the WIFI network. When the network speed of any network is smaller than the preset speed, the first transmission module indicates the first transmission module to reconnect the server. When the first communication module determines that the network is abnormal based on the TCP protocol, the first transmission module also indicates the first transmission module to reconnect the server, so that repeated reconnection can exist. By setting the reconnection status bit, the reconnection status bit is set to a preset value when the mobile phone is reconnecting, and the mobile phone can reconnect under the condition that the first communication module is not reconnecting, thereby improving the connection efficiency with the server.

The handset determines whether reconnection is in progress based on the reconnection status bit (S87). If the mobile phone is reconnecting, the mobile phone continues to monitor the user interface of the system to obtain the network speed. If the mobile phone does not perform reconnection, the mobile phone determines whether the current reconnection times reach the set reconnection times according to the value of the reconnection flag bit (S88). If the reconnection times are reached, the mobile phone releases the end cloud control channel (S89). If the number of reconnections is not reached, it is further determined whether a reconnection condition is satisfied (S810). If the reconnection condition is satisfied, reconnection is performed (S811), and if the reconnection condition is not satisfied, the mobile phone releases the end cloud control channel (S89).

If the network is disconnected, if the network is restored, the mobile phone is networked (S812), the mobile phone receives client_application_ HANDSHAKE _header information called back by the first communication module (S813), and the mobile phone is reconnected with the server to establish an end cloud control channel (S814). On the other hand, if the mobile phone is through the monitoring system user interface, the obtained network speed is greater than or equal to the preset speed (S815), it is determined that the network connection state is the connected network and the network is available, and the mobile phone and the server are reconnected to establish the end cloud control channel (S814). Under the condition that the mobile phone and the server establish an end cloud control channel, the mobile phone and the watch establish the end cloud control channel through the server.

As shown in fig. 9, the timing diagram of the above network connection method is different from the TCP-based network connection method in that the first transmission module further obtains the network speed of the network connected to the mobile phone from the system user interface, and sends a reconnection request to the server according to the network speed.

The first communication module disconnects the connection with the server according to the network disconnection indication.

After the first transmission module sends the network disconnection instruction to the first communication module, if the notification message sent by the first connection module is received, the first transmission module caches the notification message. And after the first transmission module sends the network disconnection instruction to the first communication module, if the first communication module is determined not to be reconnected, marking a reconnection flag bit, wherein the initial value of the reconnection flag bit is the set reconnection times. The first transmission module subtracts 1 from the value of the reconnection flag bit to update the value of the reconnection flag bit in the case where it is determined that the set number of reconnection times is not reached based on the value of the reconnection flag bit. And then, the first transmission module determines whether the reconnection condition is met, and if the reconnection condition is met, the first transmission module instructs the first communication module to execute reconnection action. The first communication module enters a connect state machine according to the indication information of the first transmission module, reestablishes websocket connection, and starts a timer, wherein the duration of the timer is retransmission interval. And when the duration of the timer is up, the first communication module sends a reconnection request to the server. If reconnection fails, the first communication module sends CALLBACK information of LWS_CALLBACK_CLIENT_CONNECTION_ERROR to the first transmission module, and the first transmission module disconnects websocket CONNECTION according to the CALLBACK information. And then, when the first transmission module determines that the set reconnection times are not reached according to the numerical value of the reconnection flag bit, subtracting 1 from the value of the reconnection flag bit to update the value of the reconnection flag bit, and when the reconnection condition is determined to be met, indicating the first communication module to execute reconnection operation again.

And the first transmission module determines that the set reconnection times are reached according to the value of the reconnection flag bit, and indicates the first communication module to disconnect the cloud connection channel under the condition that reconnection failure information returned by the first communication module is received. And the first communication module returns information of the release channel after disconnecting the end cloud connection channel. If the information cached in the first transmission module is not sent successfully, the first communication module returns information of failed sending to the first transmission module.

In the reconnection process, the first transmission module subtracts 1 from the value of the reconnection flag bit to update the value of the reconnection flag bit under the condition that the network connection state is determined to be network connection and the network is available according to the network speed. And then, the first transmission module determines whether the reconnection condition is met, and if the reconnection condition is met, the first transmission module instructs the first communication module to execute reconnection action. The first communication module enters a connect state machine according to the indication information of the first transmission module, reestablishes websocket connection, and starts a timer, wherein the duration of the timer is retransmission interval. When the duration of the timer is reached, the first communication module sends a reconnection request to the server, wherein the reconnection request comprises authentication information of the mobile phone side. The server returns configuration information such as authentication information and heartbeat time of the server side to the first communication module according to the reconnection request, and the first communication module sends the configuration information to the first transmission module, so that the first transmission module and the server establish heartbeat connection, the end cloud connection channel is successfully established, and the mobile phone and the watch establish an end control channel through the server. The first transmission module sends the cached notification message to the second transmission module through the terminal control channel, and the second transmission module returns the information of successful notification message reception to the first connection module after receiving the notification message.
