[0001] The present application claims priority to the Chinese patent application No. 202410868900.1, filed on June 29, 2024, and entitled "Network reconnection method, apparatus, device and communication system", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of Internet of Things, and in particular to a network reconnection method, apparatus, device and communication system. BACKGROUND

[0003] Currently, a terminal device (such as an Internet of Things device: smart door lock, refrigerator, air conditioner and other smart home products) can establish a network connection with a network device (such as a router), and a user can use the terminal device to operate and manage the terminal device. When the network connection of the terminal device is abnormal, the terminal device cannot reconnect to the network. Usually, the terminal device is manually controlled to turn on Bluetooth or a hotspot, and after searching for the terminal device, the terminal device is controlled to reestablish a network connection with the router. However, this reconnection method of the terminal device relies on manual operation and is relatively cumbersome, resulting in low reconnection efficiency of the terminal device. SUMMARY

In a case where the first identifier is verified, the first network device establishes the first connection with the terminal device, and the first connection is used to establish a network connection between the first network device and the terminal device.

[0006] Compared with the client controlling the terminal device to reestablish a network connection based on manual operation of the terminal device, in the method provided in the present application, in a case where the network connection of the terminal device is disconnected, the first identifier included in the first connection request sent by the terminal device is verified by the first network device, which indicates that the terminal device using the first user account has the first connection permission, and the first connection can be established between the terminal device and the first network device. Therefore, the terminal device automatically connects to the network device based on the first connection, thereby realizing automatic reconnection of the terminal device. In this way, the reconnection efficiency of the terminal device is improved.

[0007] In a possible implementation, the first connection is a StarFlash connection, and the first network device and the terminal device support a StarFlash communication protocol.

[0008] In this way, the first identity in the first connection request is verified by the first network device, and the first network device can start a StarFlash communication service, and a StarFlash connection can be established between the terminal device and the first network device. Subsequently, the terminal device can automatically connect to the first network device through the StarFlash connection, the automatic reconnection of the terminal device is realized, and the reconnection efficiency of the terminal device is improved.

[0009] In another possible implementation, the method further includes: receiving a network configuration request sent by the terminal device through the first connection, the network configuration request including the first encrypted information, the first encrypted information being obtained by encrypting the first user account, the first user account being used to log in the terminal device; in a case where the first user account is verified, sending the terminal device the first configuration information, the first configuration information being obtained by encrypting a network name and a network password of a network connection of the terminal device; receiving a network connection request sent by the terminal device, and establishing a network connection with the terminal device.

[0060] For the sake of clear and concise description of the following embodiments, first, the terms related to the application are briefly introduced:

[0061] Internet of Things (IoT) can be popularly understood as "Internet of Things", that is, connecting things with the Internet, and things with things exchange information and communicate through information transmission media to realize intelligent management of things. Internet of Things technology has been widely applied to daily life, for example, various smart home products in the home can be based on network interconnection, and users can remotely control the products through smart terminals or smart voice assistants.

[0062] Starlink is a new generation of short-range wireless connection technology, which integrates the advantages of Bluetooth and wireless fidelity (WIFI), aiming to provide users with anti-interference, low latency, high speed and high reliability wireless connection experience. Starlink can be applied to the field of Internet of Things technology, meet the demand of intelligent terminal, smart home, smart car and smart manufacturing terminal equipment for high-quality wireless communication, and provide more efficient and stable solutions for terminal equipment communication.

[0063] The terminal device (such as an Internet of Things device supporting Internet of Things technology) can establish a network connection with a network device, and a user can operate a client of the terminal device to manage the terminal device. However, in the case of sudden power failure, replacement of the network device, network password change, and power failure of the network device or the terminal device, the network connection between the terminal device and the network device is disconnected. In order to improve the user's experience of using the terminal device, it is necessary to restore the network connection in time, reconnect the terminal device to the network device, and reestablish the network connection between the terminal device and the network device.

[0064] In order to solve the problem of low reconnection efficiency of the terminal device, the present application provides a network reconnection method, which is executed by a first network device, and the method comprises: in the case that the network connection of the terminal device is disconnected, the first network device receives a first connection request sent by the terminal device, the first connection request is used to establish a first connection, and the first connection request comprises a first identifier. In the case that the first identifier is verified, the first network device establishes a first connection with the terminal device, and the first connection is used to establish a network connection between the first network device and the terminal device.

[0065] Compared with manually controlling the terminal device through the client of the terminal device to reestablish the network connection. In the method provided by the embodiments of the present application, in the case that the network connection of the terminal device is disconnected, the first identifier included in the first connection request sent by the terminal device is verified by the first network device, which indicates that the terminal device using the first user account has the first connection permission, and the first connection can be established between the terminal device and the first network device. Therefore, the terminal device automatically connects the network device based on the first connection, and realizes the automatic reconnection of the terminal device. In this way, the reconnection efficiency of the terminal device is improved.

[0066] FIG. 1 is a structural schematic diagram of a communication system provided by the present application. As shown in FIG. 1, the communication system 100 includes a network device 110 and a terminal device 120. The network device 110 and the terminal device 120 communicate through wireless communication technology. For example, the network device 110 and the terminal device 120 support a Wireless Fidelity (Wi-Fi) protocol (such as 802.11a / b / g / n / ac / ax / be / bn) and a Starlink communication protocol. The network device 110 and the terminal device 120 can send wireless signals that meet the relevant regulations of the Wi-Fi protocol or the Starlink communication protocol.

[0067] The network device 110 includes a router. For example, in a smart home application scenario, the router can be a WIFI router commonly used in a home, which can provide a wireless network connection function and transmit wireless signals (such as WIFI signals) to the terminal device 120 through a wireless communication manner.

[0068] In a smart home application scenario, the terminal device 120 can include, but is not limited to, a camera, a microwave oven, an air conditioner, a refrigerator, an electric water heater, and other smart home products as shown in FIG. 1. The smart home products establish a network connection with the network device 110, can realize diversified smart functions, and help improve the comfort and convenience of the living environment.

[0069] The terminal device 120 has a networking function. When the terminal device 120 is started, it can receive wireless signals broadcast by the network device 110, discover available networks, establish a wireless network connection with the network device 110, and connect to the Internet through the network device 110. The terminal device 120 can be centrally managed by an Internet of Things cloud platform, which can provide services such as device running state recording and device fault diagnosis.

[0070] The network device 110 and the terminal device 120 establish a network connection in a network configuration manner, including but not limited to an access point (AP) connection network configuration, a Bluetooth connection network configuration, a code scanning connection network configuration, and a Starlink connection network configuration. The present application does not limit the network configuration manner when the terminal device 120 and the network device 110 initially establish a network connection. When the network connection between the terminal device 120 and the network device 110 is disconnected, the specific implementation manner of the terminal device disconnecting and reconnecting can refer to the content described in steps 210 to 2130 below.

[0071] The application scenarios of the system architecture and examples described in this application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0072] Next, the network reconnection method provided by the present application will be described in detail in combination with the drawings. FIG. 2 is a flowchart of a network reconnection method provided by the present application. Here, mainly taking the interaction between the network device 110 and the terminal device 120 in FIG. 1 to realize the automatic reconnection of the terminal device as an example for description. As shown in FIG. 2, the network reconnection method can include the following contents.

[0073] In some embodiments, when the terminal device and the network device initially establish a network connection, that is, when the terminal device and the network device perform network configuration negotiation, the terminal device and the network device can perform information negotiation, including but not limited to: a first user account, a first identifier, first encryption information, etc. The first user account is used to log in to the terminal device. The first identifier is used to indicate the terminal device. The first encryption information is obtained by encrypting the first user account.

[0074] As shown in FIG. 2, in the case that the terminal device initially establishes a network connection, the first network device can generate a first identifier and first encryption information in step 210, and the first network device sends the first identifier and the first encryption information to the terminal device in step 220. Accordingly, the first network device receives the first identifier and the first encryption information in step 230.

[0075] After the network connection of the terminal device is disconnected, the terminal device and the network device can reestablish a network connection according to the verification information negotiated between the terminal device and the network device. For example, based on the first identifier, it is verified whether the terminal device has the star flash communication authority. When the terminal device and the network device reestablish a network connection, the identity of the terminal device is verified based on the first encryption information, so as to improve the security of the network connection, ensure the network security, and prevent network attacks.

[0076] For example, a client for managing the network device can be installed in the terminal device (such as a mobile phone, a tablet computer, a notebook computer, etc.), and the client of the network device can provide the function of generating the first identifier and the first encryption information, and upload the first identifier and the first encryption information to a cloud server to realize the synchronization cloud storage.

[0077] After the network device generates the first identifier and the first encryption information, the network device needs to send the first identifier and the first encryption information to the terminal device, and the terminal device receives and stores the first identifier and the first encryption information. In this way, the network device and the terminal device can obtain the verification information negotiated when the initial network configuration is successful, which provides convenience for verification when the network configuration is performed again.

[0078] In a possible example, the network device can transmit the first identifier and the first encryption information to the terminal device based on an internet protocol (IP).

[0079] In another possible example, since the first identifier and the first encryption information are stored in the cloud server, the network device can instruct the cloud server to synchronize the first identifier and the first encryption information to the terminal device.

[0080] The process in which the terminal device establishes a network connection with the network device when the network connection of the terminal device is disconnected is described below. The following steps 240 to 270.

[0081] In step 240, when the network connection of the terminal device is disconnected, the terminal device sends a first connection request. Accordingly, in step 250, the first network device receives the first connection request sent by the terminal device.

[0082] The network connection of the terminal device being disconnected includes at least one of the following: a network password being changed, the first network device being powered off or the terminal device being powered off, and the network between the first network device and the terminal device being disconnected.

[0083] For example, when the network password is changed, the terminal device needs to use the updated password to reconnect to the network. If the terminal device does not obtain the updated password in time, the terminal device will fail to pass the identity verification, thereby causing the network connection to be disconnected.

[0084] For another example, the first network device or the terminal device is powered off, and the power-off cannot maintain the current network connection, thereby causing the network connection to be disconnected. The networking indicator light on the terminal device is turned off, which can indicate that the network connection is disconnected and the terminal device is offline. The network connection being disconnected causes the terminal device to fail to access the network, resulting in a networking failure.

[0085] For another example, the network between the terminal device and the first network device fails, and the network between the terminal device and the first network device is disconnected, thereby causing the network connection of the terminal device to be disconnected.

[0086] In some embodiments, the terminal device and the network device support a star flash communication protocol. After the terminal device detects that the network connection is disconnected, the terminal device can communicate with the network device based on the star flash communication protocol, and send a broadcast message, so that the terminal device and the network device transmit information required for establishing a network connection.

[0087] For example, the terminal device sends a first connection request based on the spark-link communication protocol, and the first network device receives the first connection request sent by the terminal device. The first connection request is used to establish a first connection. The first connection can be a spark-link connection. The first connection request includes a first identifier, which can be used to indicate the terminal device, and the first identifier includes but is not limited to a universally unique identifier (UUID).

[0088] The terminal device and the network device can be pre-configured with network parameters related to the spark-link communication to support the spark-link communication protocol. The network parameters can include but are not limited to a frequency band, a channel bandwidth, and a modulation and coding mode of the spark-link communication. In addition, the spark-link transmission rate, the spark-link transmission power, and the like can also be configured in the firmware of the terminal device.

[0089] For example, in the case that the network connection of the terminal device is disconnected, the terminal device can periodically send a spark-link broadcast message based on the spark-link communication protocol at a preset time interval. The spark-link broadcast message can be used to indicate that the terminal device waits to establish a spark-link connection with the first network device, and the first identifier field is carried in the spark-link broadcast message.

[0090] The spark-link broadcast message can include a header, a payload, a checksum, and a tail, and the first identifier field is usually encapsulated in the header, so that after the first network device receives the spark-link broadcast message sent by the terminal device, the first identifier field can be processed preferentially.

[0091] The above-mentioned spark-link communication protocol can include at least one of a spark-link basic (SLB) communication interface protocol and a spark-link low energy (SLE) communication interface protocol. The SLB communication interface protocol is mainly applied to network connection scenarios with high requirements for rate and stability, such as intelligent vehicles, smart homes, and intelligent terminal devices. The SLE communication interface protocol is mainly applied to low-power network connection scenarios, such as earphones, glasses, watches, and smart wearable devices. The SLB communication interface protocol and the SLE communication interface protocol can be used in combination to meet the diversified needs of network connection scenarios.

[0092] In the case that the network connection of the terminal device is disconnected, the first network device establishes a first connection with the terminal device. The specific implementation method can refer to the following step 260.

[0093] In step 260, the first network device establishes a first connection with the terminal device in a case where the first identifier is verified. The first connection is used for the first network device to establish a network connection with the terminal device.

[0094] After the network connection of the terminal device is disconnected, the first network device can first establish the first connection with the terminal device, and the first connection is used for the first network device to establish a network connection with the terminal device. The establishment of the first connection is a basis for the first network device to reestablish a network connection with the terminal device, so as to implement automatic reconnection of the terminal device.

[0095] The first network device can store one or more identifiers associated with the first user account, for example, in a form of a list. The terminal device and the first network device have negotiated to use the first identifier as verification information for network disconnection and reconnection when establishing a network connection. For example, the first identifier can be a UUID negotiated by the terminal device and the first network device when initially establishing a network connection. The first network device can verify the first identifier in the first connection request according to the one or more identifiers.

[0096] The first network device can verify the first identifier in the first connection request sent by the terminal device based on the one or more identifiers stored by the first network device and associated with the first user account. In a case where the first identifier is included in the one or more identifiers, it is determined that the first identifier is verified.

[0097] For example, the first network device can compare each identifier in the one or more identifiers with the first identifier respectively. If any identifier in the one or more identifiers is the same as the first identifier, the first identifier passes the verification of the network device, indicating that the first identifier sent by the terminal device is verified successfully.

[0098] In a possible implementation, the first network device can directly compare each identifier in the one or more identifiers with the first identifier sent by the terminal device in a string. If the lengths of the strings of the two identifiers are equal, and the characters at each corresponding position in the strings are equal, the first identifier is included in the one or more identifiers, and the first identifier is verified.

[0099] In another possible implementation, the first identifier sent by the terminal device can be a first hash value encrypted by a hash encryption algorithm, and each identifier stored by the first network device can be a second hash value encrypted by the hash encryption algorithm. The first hash value is compared with the second hash value. If the first hash value is the same as the second hash value, the first identifier is included in the one or more identifiers, and it is determined that the first identifier passes the verification. Instead of comparing the first identifier itself, the hash values are compared, which can reduce the risk of illegal tampering of the user account and prevent user information leakage. In addition, the first identifier passing the verification can also ensure network security and prevent network attacks.

[0100] Optionally, as shown in FIG. 3, after the first identifier included in the first connection request passes the verification of the first network device, the first network device can send a first connection response to the terminal device (step 270). The first connection response is used to indicate that the first identifier in the first connection request passes the verification.

[0101] For example, when the first connection is a star flash connection, the star flash communication service start identifier can be included in the first connection response. The first network device starts the star flash communication service, grants the terminal device the permission to perform star flash communication with the first network device, and the terminal device can access the star flash communication, and the first network device and the terminal device establish the star flash connection based on the star flash communication.

[0102] In this way, when the first identifier included in the first connection request passes the verification of the first network device, the first network device can start the star flash communication service, and the terminal device and the first network device can establish the star flash connection. In this way, the terminal device can automatically connect the first network device through the star flash connection in the future, realizes the automatic reconnection of the terminal device, and improves the reconnection efficiency of the terminal device.

[0103] The terminal devices in the same application scenario (for example, the smart home scenario) can be produced by different manufacturers, but the users using the terminal devices are unique. The first identifier can be used to indicate that the terminal device is associated with the user account, and the first network device can use a unified user account to perform authentication management on the terminal devices, without relying on the device information of the terminal devices. In addition, the first network device uses the unified user account to perform authentication management on the terminal devices, and even if the installation location of the terminal device is changed, the automatic reconnection capability of the terminal device will not be affected, which provides convenience for the reconnection of the terminal device and is also conducive to improving the reconnection efficiency of the terminal device.

[0104] After the first connection between the first network device and the terminal device is successfully established, the first network device and the terminal device can reestablish a network connection through the first connection to realize the network disconnection and reconnection of the terminal device. FIG. 3 is a flowchart of reestablishing a network connection between a network device and a terminal device according to an embodiment of the present application. The specific interaction process is described by the following steps 280 to 2130.

[0105] In step 280, the terminal device sends a network configuration request to the first network device. Correspondingly, in step 290, the first network device receives the network configuration request sent by the terminal device through the first connection.

[0106] The network configuration request can include first encryption information, which is obtained by encrypting the first user account, for example, by using a key algorithm to encrypt the first user account. The first encryption information can be used to ensure the security of the first user account and prevent attackers from illegally obtaining user information.

[0107] The key algorithm can include, but is not limited to, a message-digest algorithm 5 (MD5), a security hash algorithm 1 (SHA1), and a hash-based message authentication code (HMAC), etc. For example, the first user account is encrypted using SHA1 to obtain a first user account HASH value, which can be used as the first encryption information.

[0108] Optionally, the network configuration request can also include a timestamp mask. The timestamp mask can be used to indicate the time when the terminal device sends the network configuration request to the first network device. As a security mechanism, the timestamp mask can ensure the uniqueness of each communication between the terminal device and the first network device, and the first network device can identify invalid or expired network configuration requests to prevent security risks caused by replay attacks.

[0109] In step 2100, the first configuration information is sent to the terminal device if the first user account is verified. Correspondingly, in step 2110, the terminal device receives the first configuration information sent by the first network device.

[0110] In order to ensure that the first network device and the terminal device establish a secure network connection, the first network device can verify the first identity before starting the star flash communication service, and further, the first network device can also verify the first user account after receiving the network configuration request.

[0111] In some embodiments, the first network device can decrypt the first encrypted information in the network configuration request sent by the terminal device according to the same key algorithm, i.e., the key algorithm used when the terminal device encrypts the first user account, to obtain the first user account. In the case where the first user account is the same as the user account stored by the first network device during the network configuration negotiation, the first user account is determined to pass the verification.

[0112] For example, the first user account and the user account stored by the first network device are compared in string. If the string lengths of the two user accounts are equal, and the characters at each corresponding position in the string are equal, the first user account is the same as the user account stored by the first network device, and thus the first user account passes the verification.

[0113] In the case where the first user account passes the verification, the identity of the terminal device passes the verification of the network device, indicating that the first encrypted information sent by the terminal device passes the verification. After the first user account passes the verification, the first network device can send the first configuration information to the terminal device. The first configuration information can include a network name and a network password used by the terminal device to establish a network connection. Alternatively, the first configuration information is encrypted using a key algorithm, such as an encrypted WIFI name and WIFI password.

[0114] Step 2120, the first network device establishes a network connection with the terminal device.

[0115] After the terminal device receives the first configuration information, in order to establish a network connection with the first network device, the terminal device can send a network connection request to the first network device. Correspondingly, the first network device receives the network connection request sent by the terminal device. The first network device can send a network connection indication to the terminal device in response to the network connection request sent by the terminal device, indicating that the terminal device can establish a network connection with the first network device according to the first configuration information. In this way, the first network device and the terminal device reestablish a network connection.

[0116] Since the first configuration information received by the terminal device is encrypted by the first network device, the terminal device needs to use the same key algorithm as when the first configuration information is encrypted to decrypt the first configuration information, so as to obtain the network name and the network password. The terminal device reestablishes a network connection with the first network device according to the network name and the network password.

[0117] In some embodiments, after the first network device and the terminal device reestablish a network connection, the first network device can close the star flash communication service and release network resources in a timely manner.

[0118] Optionally, the first network device can also update the first identifier, update the first identifier to the second identifier, and upload the updated second identifier to the cloud server.

[0119] Optionally, the first network device can also send indication information to the terminal device (step 2130), and accordingly, the terminal device receives the network connection request sent by the first network device, indicates that the first identifier is updated to the second identifier, and the terminal device updates the first identifier to the second identifier. Thus, the updated second identifier is stored in the cloud server and the terminal device. If the network connection of the terminal device is disconnected with the first network device again subsequently, the terminal device reconnects to the network.

[0120] In the case that the network connection of the terminal device is disconnected, if the first identifier included in the first connection request sent by the terminal device is verified by the first network device, it indicates that the terminal device using the first user account has the first connection permission, and the first connection between the terminal device and the first network device can be established. Therefore, the terminal device automatically connects the network device based on the first connection, and realizes the automatic reconnection of the terminal device. In this way, the reconnection efficiency of the terminal device is improved.

[0121] In some possible implementation cases, after the terminal device initially establishes the network connection with the second network device, the network connection of the terminal device is disconnected, and the terminal device cannot establish the network connection with the second network device again. In this case, the network device is replaced, that is, the second network device is replaced by the first network device. In this case, the first connection between the replaced first network device and the terminal device is established, and the specific implementation method can also be referred to the following description. In an application scenario, the first network device and the second network device are located at different positions, and the coverage range of the first network device and the coverage range of the second network device are different. The terminal device is located in the coverage range of the second network device, and the terminal device and the second network device perform network configuration negotiation and establish the network connection. The terminal device moves, and the position of the terminal device can change. The terminal device moves out of the coverage range of the second network device, and the network connection between the terminal device and the second network device is disconnected. When the terminal device moves into the coverage range of the first network device, the terminal device can initiate the network reconnection to the first network device according to the network reconnection method provided in the present application, and establish the network connection with the first network device. The first network device and the second network device save and / or log in the same user account, and the terminal device establishes the network connection with the first network device and the second network device according to the user account.

[0122] For example, the router at home and the router at office save or / and log in the same user account. The user's mobile phone negotiates with the router at home for the first time and establishes a network connection. When the user's mobile phone moves out of the coverage of the router at home, the network connection between the user's mobile phone and the router at home is disconnected. If the user's mobile phone moves into the coverage of the router at office, the user's mobile phone does not need to negotiate with the router at office again in the case that the router at office and the user's mobile phone log in the same user account as the router at home. The user's mobile phone can initiate network reconnection to the router at office according to the network reconnection method provided in the present application, and establish a network connection with the router at office by verifying the mobile phone identifier (such as UUID) and the user account encryption information corresponding to the user account saved by the router at office. As shown in steps 410 and 420 and the description of steps 240 to 2130 in FIG. 4.

[0123] FIG. 4 is a flow diagram of another network reconnection method provided in an embodiment of the present application. The difference between the network reconnection method shown in FIG. 4 and the network reconnection methods shown in FIGS. 2 and 3 is that the terminal device establishes a primary network connection, and the terminal device and the second network device establish a primary network connection. In the case of changing the network device, the second network device sends the first identifier and the second encryption information to the first network device (step 410). Correspondingly, the first network device receives the first identifier and the second encryption information sent by the second network device, and stores the first identifier and the second encryption information (step 420). The second encryption information is encrypted from the first user account, the first user account is used to log in the terminal device, and the first identifier and the second encryption information are obtained by negotiation when the second network device and the terminal device establish the primary network connection. The specific negotiation process can refer to the negotiation process of the first network device to the first network device described above, and will not be described herein.

[0124] Optionally, the first network device can also decrypt the second encryption information to obtain the first user account, and store the first identifier and the first user account.

[0125] Optionally, the second network device can upload the first identifier and the second encryption information to the cloud server to realize synchronized cloud storage.

[0126] Optionally, the second network device can also instruct the first network device to obtain the first identifier and the second encryption information from the cloud server. Then, the first network device can obtain the first identifier and the second encryption information from the cloud server.

[0127] In a case where the first network device acquires and stores the first identifier and the first user account, the first network device can establish a network connection with the terminal device. For example, the first network device receives a first connection request sent by the terminal device, the first connection request is used to establish a first connection, the first connection request includes the first identifier, the first identifier is used to indicate the terminal device; in a case where the first identifier is verified, the first network device establishes the first connection with the terminal device, and the first connection is used to establish the network connection between the first network device and the terminal device. For the process in which the first network device establishes the network connection with the terminal device in a case where the network connection of the terminal device is disconnected, reference can be made to the description of the process (steps 240 to 2130) in which the first network device establishes the network connection with the terminal device, and details are not described herein again.

[0128] In a case where the network device is replaced, and the first identifier included in the first connection request sent by the terminal device is verified by the first network device in a case where the network connection of the terminal device is disconnected, it is indicated that the terminal device using the first user account has the first connection permission, and the first connection can be established between the terminal device and the first network device. Therefore, the terminal device automatically connects the network device based on the first connection, and automatic reconnection of the terminal device is realized. In this way, the reconnection efficiency of the terminal device is improved.
