Description

Method and device for recovering terminal disconnection

Technical field

The present invention relates to the field of communications, and in particular, to a method and device for recovering a terminal disconnection.

Background technique

In the process of mobile device management (MDM) projects, it is often necessary to access the PUSH delivery function. That is, the server unidirectionally sends a notification or a control command to the terminal, and the terminal performs a corresponding operation after receiving the notification or the control command.

However, in practical applications, after the terminal runs for a period of time, it often happens that the PUSH server is disconnected. If the terminal does not succeed after retrying multiple connections, it will be completely disconnected from the server.

The transmission device is used to receive or transmit data via a network. The above specific examples of the network may include a wireless network provided by a communication provider of the terminal. In one example, the transmission device includes a network adapter (Network Interface Controller, NIC for short), which can be connected to other network equipment through a base station so as to communicate with the Internet. In one example, the transmission device may be a radio frequency (RF) module, which is used to communicate with the Internet in a wireless manner.

This method embodiment mainly solves the problem of how to restore the connection between the lost terminal and the server after the terminal loses contact with the server and cannot normally receive messages sent by the server. The application scenario of the embodiment of the present invention is mainly applicable to a scenario in which multiple terminals are relatively concentrated (for example, between terminals used by colleagues of the same company), and the server sends a message at a fixed time (for example, during office hours). In this way, it is easy to match through the near field communication connection between different terminals.

In the above application scenario, by using the technical solution provided by the embodiment of the present invention, the connection between the lost terminal and the server can be quickly restored, so as to ensure that the lost terminal can receive the server's message in time, thereby reducing the cause of the problem. Adverse effects caused by message loss.

Examples of specific application scenarios of the foregoing method for recovering terminal disconnection: (1) Bring your own device (Bring, Your, Own, Device, or BYOD for short) application, that is, mobile office, this scenario includes mobile phones, tablets, and communication Other terminals of the module; (2) all kinds of intelligent hardware in the smart home are interconnected through home Wi-Fi, which helps to monitor and locate the status of the home network and the connection status of each intelligent terminal to strengthen the management and troubleshooting of the intelligent terminal (3) Internet of vehicles; (4) Industrial Internet, such as water and electricity monitoring terminals with wireless communication modules; (5) Shared bicycles.

In the method for recovering the terminal disconnection, the normal terminal is used to wake up the lost terminal and send a message issued by the server in the lost connection state to the lost terminal. The subsequent method embodiments of the embodiments of the present invention involve the cooperation of the terminal application and the server. The following describes the processing procedures of the terminal application and the server, respectively, and sends a message sent by the server to the normal terminal and how the normal terminal wakes up. The terminal is explained in detail.

This embodiment provides a method for recovering a terminal disconnection running on the server, which is applied to the server side. FIG. 2 is a flowchart of a method for recovering a terminal from being disconnected according to an embodiment of the present invention. As shown in FIG. 2, the process includes the following steps:

Step S22: After determining that the first terminal is currently in a disconnected state, search for the second terminal according to the device information of the first terminal, where the device information includes at least the geographic location of the first terminal and the near field communication connection method of the first terminal Identification

In step S24, a wake-up message is sent to the second terminal so that the second terminal wakes up the first terminal, where the wake-up message includes at least: a near field communication connection mode identifier.

In the related art, the server is usually reconnected by retrying or restarting the lost terminal. However, because the lost terminal is not clear whether the connection failure is caused by the terminal itself or the server, the lost terminal will choose to perform the restart operation after retrying a few times for a long time. Waste a lot of time. If the server sends a very important message during this time period, the terminal cannot receive it normally, which will have an immeasurable serious impact on subsequent operations. Through the above steps, after the first terminal is disconnected, if the server can determine that the message sent by the server to the first terminal has not been received by the first terminal, it can send a wake-up message to the second terminal to make the first terminal The second terminal wakes up the first terminal and reconnects to the server. Therefore, the problem of simply relying on the disconnected terminal to retry to connect to the server repeatedly in the related technology cannot ensure the rapid recovery of the lost terminal, so that the lost terminal can perform the operation indicated by the server and be able to The effect of quickly restoring the connection to the server.

In an embodiment, the execution subject of the above steps may be a server, but is not limited thereto.

In an embodiment, the wake-up message further includes a message (for example, a notification or a control command) issued by the server to the first terminal to instruct the first terminal to perform a corresponding operation.

In an embodiment, during the process of sending the wake-up message by the server to the second terminal, the server may both carry the specific message part in the wake-up message, so that the second terminal forwards the specific message part to the first terminal, so that the first The terminal completes the operation previously instructed by the server. Of course, the server may no longer carry the specific message part in the wake-up message, but only sends the wake-up message to the second terminal, so that the second terminal wakes up the first terminal. After the first terminal successfully reconnects with the server, the server may receive a message originally intended to be sent to the first terminal again from the server, so as to perform a corresponding operation.

In an embodiment, in step S22, finding the second terminal according to the device information of the first terminal may include the following execution steps:

Step S221: Find a plurality of terminals in a preset range where the first terminal is located according to the geographic location, where the plurality of terminals maintain a connection state with the server;

In step S222, a second terminal to be used is selected from a plurality of terminals.

After the server issues the PUSH command, it will check which terminals did not return a receipt message. For a terminal that does not return a receipt message, the server will find the geographical location and near-field communication connection identifier reported by the most recently lost terminal that did not return a receipt message, and find a normal terminal that is closest to the geographical location of the lost terminal , And then send the no-acknowledgement message just sent to the normal terminal together with the near field communication connection mode identifier of the lost terminal.

Of course, in addition to selecting the normal terminal with the nearest geographic location, other methods of selecting a normal terminal can also be used, such as: selecting the terminal that has the longest connection status with the server, or selecting the connection status with the server The terminal with the strongest signal does not constitute an improper limitation on the embodiment of the present invention.

In an embodiment, before determining that the first terminal is currently in a disconnected state in step S22, the method may further include the following execution steps:

Step S21: Receive device information reported by the first terminal, where the device information further includes: a password generating element, which is used to determine an encrypted password identified by a near field communication connection mode.

The terminal normally reports device information before being in a disconnected state, where the device information includes but is not limited to: geographic location, identification of the near field communication connection method (for example: Bluetooth address, wireless fidelity (WiFi) address, near field communication (NFC) ) Tag, etc.), and the receipt message returned to the server after receiving the message from the server to inform the server that the terminal has received the issued message. When the server finds that the specific terminal (for example, the first terminal) has not sent a receipt message, it sends a message to another terminal (for example, the second terminal) near the first terminal according to the geographical location previously reported by the terminal.

In an optional embodiment, for the connection between the terminals, specific security mechanisms need to be followed, such as Bluetooth addresses, WiFi hotspot passwords, etc., which need to be generated in accordance with specific security policies. Terminals need to abide by this security policy at the same time. For example, in a normal working state, the lost terminal will encrypt the information such as the WiFi hotspot password or Bluetooth address, and the elements that generate the encrypted password, such as the International Mobile Equipment Identity ), Report to the server.

In an optional embodiment, the wake-up message may further include: a password generation element.

After the terminal loses contact, the server sends the encrypted password and the elements that generate the encrypted password to the normal terminal, so that the normal terminal parses out the encrypted password according to a predetermined policy and the element that generates the encrypted password.

In an optional embodiment, the foregoing pre-agreed policy may be a random password generation policy, and the random password generation policy includes but is not limited to one of the following ways:

(1) Generated based on the timestamp, this timestamp can be the Wi-Fi hotspot on time or other attributes related time of the current device;

(2) Based on the current device attributes, including but not limited to: hardware attributes (for example: media access control (Mac) address, etc.);

(3) Multiple information combinations, such as: time stamp + device attributes;

(4) Encoding or encryption based on the information listed in (1)-(3) above.

FIG. 3 is a flowchart of a server processing procedure for a disconnected terminal according to an optional embodiment of the present invention. As shown in FIG. 3, the process may include the following processing steps:

Step S302: The server sends a message to the terminal according to the terminal identifier.

In step S304, the server queries whether the terminal returns a receipt. If yes, then the issuing process ends, and if no, proceed to step S306.

Step S306: For a terminal that does not return a receipt, the server finds out the device information reported by the terminal, which is mainly the geographic location and the near-field communication connection mode identifier.

Step S308: The server finds a normal terminal in the vicinity of the lost terminal according to the geographic location of the lost terminal.

Step S310: The server encapsulates the message just sent to the lost terminal and the near field communication connection mode identifier of the terminal into a specific message.

Step S312: The server sends the encapsulated message to a normal terminal near the lost terminal.

In this embodiment, another method for recovering a terminal disconnection running on the networked terminal is provided. FIG. 4 is a flowchart of another method for recovering a terminal disconnection according to an embodiment of the present invention, as shown in FIG. 4. The process includes the following steps:

Step S42: Receive a wake-up message issued by the server, where the wake-up message includes at least: a near field communication connection mode identifier to be forwarded to the lost terminal;

Step S44, analyzing the near field communication connection mode identifier from the wake-up message;

In step S46, the identifier of the lost terminal is matched according to the near field communication connection mode to wake up the lost terminal.

After the server sends the PUSH message, it checks which terminals have not sent a receipt message to determine that these terminals are in a disconnected state, and then finds the geographical location reported by these lost terminals before it then connects the near field communication method of the lost terminals. The identification is sent to normal terminals near these lost terminals.

After receiving the message sent by the server, the normal terminal matches the identification of the near field communication connection method (for example, Bluetooth address) of the lost terminal, and matches the lost terminal through the near field communication method (for example, Bluetooth), so that the lost terminal restarts. The local application reconnects with the server.

In an embodiment, the wake-up message further includes: a message part to be forwarded to the lost terminal;

In step S44, the method further includes: parsing the message part from the wake-up message;

In step S46, the method further includes: forwarding the message part to the lost contact terminal, so that the lost contact terminal performs an operation corresponding to the message part.

In the process of sending the wake-up message by the server to the network-connected terminal, the server can either carry the specific message part in the wake-up message, so that the network-connected terminal forwards the specific message part to the lost-connection terminal, so that the lost-connection terminal completes the operation previously instructed by the server. Of course, the server may no longer carry the specific message part in the wake-up message, but only sends the wake-up message to the networked terminal, so that the networked terminal wakes up the disconnected terminal. After the reconnected terminal and the server are successfully reconnected, the server may again receive the message originally intended to be sent to the lost terminal, so as to perform the corresponding operation.

In one embodiment, the message further includes: a password generation element, which is used to determine an encrypted password for the near field communication connection mode identification. In step S44, parsing the near field communication connection mode identification from the message may include the following: Steps:

Step S441: Determine the encryption password according to the password generation element.

In step S442, the identification of the near field communication connection mode is parsed by using the encrypted password and a predetermined password generation strategy.

For the connection between the terminals, specific security mechanisms need to be followed, such as Bluetooth addresses, WiFi hotspot passwords, etc., which all need to be generated in accordance with specific security policies. The terminals need to comply with the security policy at the same time. For example, in a normal working state, the lost terminal reports the encrypted Bluetooth address or WiFi hotspot password and other elements (such as IMEI) to the server. After the terminal is disconnected, the server sends the password and the element generating the encrypted password to the normal terminal, and the normal terminal parses the encrypted password according to a predetermined policy and the element generating the encrypted password.

(3) Multiple information combinations, such as: time stamp + device attributes;

(4) Encoding or encryption based on the information listed in (1)-(3) above.

In an embodiment, in step S46, forwarding the message part to the terminal may include the following execution steps:

Step S461, when the end time of the preset time interval is reached, the near field communication connection mode corresponding to the near field communication connection mode identifier is turned on;

In step S462, the message part is forwarded to the terminal through the near field communication connection method, and after it is determined that the message part is sent, the near field communication connection method is closed.

For terminal devices that are sensitive to power consumption, such as the Internet of Things, WiFi or Bluetooth will always have higher power consumption, so you can consider turning on WiFi or Bluetooth at preset time intervals, for example, at half an hour or the entire hour At any time, turn on for a few minutes at a time. When a message to be processed is detected, WiFi or Bluetooth will be turned off immediately after the message is processed. For a normal terminal, after receiving a message from the server to wake up the lost terminal, when the opening time is reached, send a message to the lost terminal, and immediately turn off WiFi or Bluetooth after sending the message to the lost terminal. If no message is received, turn off WiFi or Bluetooth in a short time.

In an optional embodiment, the terminal periodically reports the geographic location and the near field communication connection mode identifier to the server under normal circumstances. After receiving a message from the server, the normal terminal first needs to parse the message issued by the server. If it is a control command on the normal terminal, execute the command. If it is a message to wake up other devices, the near-field communication connection mode identifier is parsed for matching, and a message or file is sent after the matching is successful.

FIG. 5 is a flowchart of a process for a server to wake up a lost terminal by sending a message to a normal terminal according to an optional embodiment of the present invention. As shown in FIG. 5, the process may include the following processing steps:

Step S502: The normal terminal receives a message delivered by the server.

Step S504: The normal terminal checks the type of the message by analyzing the message.

In step S506, the normal terminal determines whether it is a message to wake up other terminals, and if not, performs related operations, and if so, proceeds to step S508.

In step S508, the normal terminal encapsulates the message that needs to be sent to the lost terminal, which can be assembled into a file, and the encapsulation form is not limited to this.

Step S510: The normal terminal matches the surrounding terminals according to the resolved near-field communication connection mode, and connects the lost terminals.

In step S512, the normal terminal sends a message that has been encapsulated to the lost terminal.

In this embodiment, another method for recovering a terminal disconnection running on the disconnected terminal is provided. FIG. 6 is a flowchart of another method for recovering a terminal disconnection according to an embodiment of the present invention, as shown in FIG. 6. The process includes the following steps:

In step S62, the wake-up message forwarded by the networked terminal is received through the near field communication connection method, wherein the wake-up message is issued by the server, and the near field communication connection method is determined by the near field communication connection mode identifier reported by the local application of the lost terminal. The connection status between the servers is maintained;

In step S64, in response to the wake-up message, the local application is restarted to try to restore the connection with the server.

The method of restoring the contact between the lost terminal and the server through other normal terminals. The server uses the geographical location to filter which normal terminals are near the lost terminal. Neither the lost terminal nor the normal terminal need to report other hardware information and install third-party applications APP).

Before the connection is lost, the terminal normally reports the device information (including the geographical location and the identification of the near field communication connection mode). After the terminal loses contact, it will be woken up by a normal terminal and restart the application to connect to the server.

In an embodiment, in step S64, the method may further include: parsing the message part from the wake-up message, and performing an operation corresponding to the message part.

In the process of sending the wake-up message by the server to the network-connected terminal, the server can either carry the specific message part in the wake-up message, so that the network-connected terminal forwards the specific message part to the lost-connection terminal, so that the lost-connection terminal completes the operation previously indicated by the server. Of course, the server may no longer carry the specific message part in the wake-up message, but only sends the wake-up message to the networked terminal, so that the networked terminal wakes up the disconnected terminal. After the reconnected terminal and the server are successfully reconnected, the server may again receive the message originally intended to be sent to the lost terminal, so as to perform the corresponding operation.

In an alternative embodiment, FIG. 7 is a flowchart of a process for waking up a disconnected terminal by sending a message through a normal terminal according to an alternative embodiment of the present invention. As shown in FIG. 7, the process may include the following processing steps :

Step S702: The lost terminal receives a message sent by a normal terminal through a near field communication connection.

In step S704, the APP of the disconnected terminal monitors the message, and the message can be monitored through broadcast or other methods.

Step S706: The lost terminal parses the message received from the normal terminal.

Step S708: The lost terminal performs corresponding actions according to the content of the message, for example, turning off WiFi, cameras, and the like for management and control.

In step S710, after performing the corresponding action, the lost terminal restarts the local application to try to reconnect to the server.

In one embodiment, the device information further includes: a password generation element, which is used to determine an encrypted password identified by the near field communication connection method. Before receiving the message forwarded by the terminal through the near field communication connection method in step S62, It can include the following steps:

Step S60: Generate an encrypted password according to the password generation element and a predetermined password generation policy;

In step S61, the near field communication connection mode identifier is encrypted by using an encryption password.

(3) Multiple information combinations, such as: time stamp + device attributes;

(4) Encoding or encryption based on the information listed in (1)-(3) above.

In an embodiment, in step S62, receiving the message forwarded by the terminal through a near field communication connection may include the following execution steps:

Step S621, when the end time of the preset time interval is reached, the near field communication connection mode is turned on;

In step S622, the message is received through the near field communication connection mode, and after it is determined that the message is sent, the near field communication connection mode is closed.

For terminal devices that are sensitive to power consumption, such as the Internet of Things, WiFi or Bluetooth will always have higher power consumption, so you can consider turning on WiFi or Bluetooth at preset time intervals, for example, at half an hour or the entire hour At any time, turn on for a few minutes at a time. When a message to be processed is detected, WiFi or Bluetooth will be turned off immediately after the message is processed. For the disconnected terminal, when the opening time is reached, after receiving the message sent by the normal terminal, the WiFi or Bluetooth is turned off immediately.
