Mobile device management and control method and apparatus

A mobile device management and control method, comprising the following steps:

• S1) operating, by a web end, a policy form, and sending policy form data obtained after the operation is completed to a server for processing and generating a policy form code;
• S2) requesting, by a mobile terminal, to obtain the policy form code from the server, sending, by the mobile terminal, a unique identifier of the mobile terminal and the policy form code to the server for processing and generating the unique identifier to be returned to the mobile terminal, and
• performing, by the mobile terminal, a hash algorithm operation on the unique identifier and a private key, and performing md5 encryption to generate encoded data, wherein the encoded data is exchanged between the mobile terminal and the server at intervals, to ensure a stable connection between the mobile terminal and the server;
• S3) sending, by the mobile terminal, the unique identifier to the server, and querying, by the server, a secure memory area to obtain policy data and returning the policy data to the mobile terminal, wherein the secure memory area stores the unique identifier and a network license corresponding to the unique identifier, and
• after the mobile terminal receives the policy data and the policy data takes effect, the mobile terminal establishes a stable persistent connection to the server;
• S4) after the persistent connection takes effect, sending, by the web end, a policy command that needs to be changed to the server, sending, by the server, a response instruction to the mobile terminal, responding, by the mobile terminal, to a success flag after receiving the response instruction, managing and controlling, by the server, the mobile terminal by using the success flag, and managing and controlling, by the web end, the mobile terminal by requesting to obtain a management and control state of the server;
• and
• S5) presetting a maximum connection time for the persistent connection between the mobile terminal and the server, and when a time for the persistent connection is greater than the maximum connection time, disconnecting the mobile terminal from the server, and suspending, by the mobile terminal, ongoing tasks, wherein the tasks comprise downloading data and requesting data, to reduce resource consumption caused by the persistent connection;
• and when the mobile terminal sends α kilobyte (KB) data to the server, wherein α≥0, the mobile terminal splits the data into β pieces, and separately transmits the β pieces of data to the server, wherein β is a positive integer, thereby reducing a data loss caused by a data packet loss.
