[0019] With the rapid development of IoT technology, more and more terminal devices need to access the network to achieve interconnection. As an open source distributed operating system for all scenarios, OpenHarmony is committed to providing a unified system platform for various terminal devices. OpenHarmony supports multiple communication protocols, including Wi-Fi, Bluetooth, ZigBee, NFC, etc., which can realize device discovery across network domains and expand the scope of device access.

[0020] In the OpenHarmony system, the access link of the terminal device is crucial. In the prior art, when a terminal device accesses the OpenHarmony system, it is usually directly connected to the OpenHarmony system after identity authentication. This access method will affect the effective operation of the Internet of Things system. To this end, the present application provides an access method, device and storage medium for a terminal device based on OpenHarmony to solve the above problems.

[0021] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0022] See also Figure 1 , Figure 1 A flow chart of a method for accessing a terminal device based on OpenHarmony provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the access method of the terminal device based on OpenHarmony provided in the embodiment of the present application includes steps S1 to S5.

[0023] Step S1, responding to an access request from a terminal device, and performing identity authentication on the terminal device and a target OpenHarmony system based on a preset identity authentication mechanism.

[0024] Step S2: If the authentication is successful, obtain the device information of the terminal device; wherein the device information includes the communication protocol, communication bandwidth and priority of the terminal device.

[0025] Step S3: Determine whether the remaining bandwidth of the target network corresponding to the communication protocol is greater than the communication bandwidth.

[0026] Step S4: If yes, connect the terminal device to the target network based on the communication bandwidth.

[0027] Step S5: If not, the terminal device is connected to the target network based on the preset device access rule, the priority, the communication bandwidth and the remaining bandwidth.

[0028] It should be noted that the execution entity of the embodiment of the present application can be a server or an access device of a terminal device based on OpenHarmony. The following description will be made using a server as an example.

[0029] As described in the above step S1, in response to the access request of the terminal device, the terminal device and the target OpenHarmony system are authenticated based on the preset authentication mechanism. Specifically, after the target OpenHarmony system discovers the terminal device, it notifies the server of the access request of the terminal device. After the server receives the access request sent by the target OpenHarmony system, it authenticates the terminal device and the target OpenHarmony system. It can be understood that traditional device access methods usually only verify the terminal device, while step S1 verifies both the terminal device and the target OpenHarmony system, which helps to establish a trust relationship between the terminal device and the target OpenHarmony system, ensuring that both parties are authorized entities and have an association relationship, providing a basis for the effective operation of the Internet of Things system.

[0030] As described in the above step S2, if the authentication is successful, the device information of the terminal device is obtained. Specifically, the server obtains the device information of the terminal device in the device information database based on the device identification of the terminal device, wherein the device information database is provided with a correspondence between the device identification and the device information. It should be noted that the verification in this embodiment not only indicates that both the terminal device and the target OpenHarmony system are authorized entities, but also indicates that the terminal device and the target OpenHarmony system have an associated relationship.

[0031] As described in step S3 above, it is determined whether the remaining bandwidth of the target network corresponding to the communication protocol is greater than the communication bandwidth. Specifically, the server determines the target network based on the communication protocol, obtains the remaining bandwidth of the target network through the bandwidth monitoring device of the target network, and determines whether the remaining bandwidth is greater than the communication bandwidth.

[0032] As described in the above step S4, if yes, the terminal device is connected to the target network based on the communication bandwidth. Specifically, if the remaining bandwidth is greater than the communication bandwidth, the server connects the terminal device to the target network and allocates a bandwidth equal to the communication bandwidth to the terminal device. It can be understood that when the remaining bandwidth is greater than the communication bandwidth, the method of step 4 is used to connect the terminal device to the target network, which can ensure the effective operation of the target device in the Internet of Things system and the effective use of bandwidth resources.

[0033] As described in the above step S5, if not, the terminal device is connected to the target network based on the preset device access rule, the priority, the communication bandwidth and the remaining bandwidth. Specifically, if the remaining bandwidth is not greater than the communication bandwidth, the server connects the terminal device to the target network based on the preset device access rule, the priority, the communication bandwidth and the remaining bandwidth. Wherein, the step of connecting the terminal device to the target network based on the preset device access rule, the priority, the communication bandwidth and the remaining bandwidth includes the following steps: Determine whether a target access device exists in the target network; the priority of the target access device is lower than the priority of the terminal device; If not, connecting the terminal device to the target network based on the remaining bandwidth; it can be understood that the actual communication bandwidth of the terminal device at this time is the remaining bandwidth; If so, determining whether the access bandwidth of the target access device is greater than the bandwidth difference between the communication bandwidth and the remaining bandwidth; If so, a portion of the access bandwidth of the target access device is allocated to the terminal device based on a preset bandwidth allocation method; wherein the bandwidth value of the portion of the access bandwidth is consistent with the bandwidth difference; it can be understood that at this time, the portion of the access bandwidth is released, and the sum of the bandwidth value of the released portion of the access bandwidth and the remaining bandwidth is consistent with the bandwidth value of the communication bandwidth; Connecting the terminal device to the target network based on the communication bandwidth; it can be understood that the actual communication bandwidth of the terminal device at this time is the communication bandwidth; If not, determining whether the priority of the terminal device is higher than a preset priority; If so, the target access device is disconnected, and the terminal device is connected to the target network based on the access bandwidth and the remaining bandwidth; it can be understood that the actual communication bandwidth of the terminal device at this time is the sum of the access bandwidth and the remaining bandwidth; If not, the terminal device is connected to the target network based on the remaining bandwidth; it can be understood that the actual communication bandwidth of the terminal device at this time is the remaining bandwidth.

[0034] It can be understood that step S5 ensures that key devices in the IoT system receive priority support when bandwidth resources are tight, which helps maintain the effective operation of the IoT system.

[0035] The method provided in this embodiment, on the one hand, realizes mutual verification of the terminal device and the target OpenHarmony system by authenticating the terminal device and the target OpenHarmony system based on a preset identity authentication mechanism, which helps to establish a trust relationship between the terminal device and the target OpenHarmony system, ensures that both parties are authorized entities and have an associated relationship, and provides a basis for the effective operation of the Internet of Things system. On the other hand, when the remaining bandwidth is not greater than the communication bandwidth, the terminal device is connected to the target network based on the preset device access rules, the priority, the communication bandwidth and the remaining bandwidth, thereby ensuring that key devices in the Internet of Things system receive priority support when bandwidth resources are tight, which helps to maintain the effective operation of the Internet of Things system.

[0038] In this embodiment, after determining whether the number of characters in the target character sequence is an integer multiple of the number of identical characters, the method further includes: If not, add target numbers in sequence after the target character sequence until the number of characters in the target character sequence is an integer multiple of the number of identical characters, thereby obtaining a final character sequence; The final character sequence is segmented based on the number of identical characters to obtain a plurality of character subsequences; wherein the number of characters in each of the character subsequences is equal to the number of identical characters; Arranging each of the character subsequences in order from top to bottom in a preset matrix bracket based on the position of each of the character subsequences in the final character sequence to obtain a target matrix; The target matrix is ​​multiplied by the target column vector to obtain the target authentication information.
