Method and device for recording data of terminal

A device for recording data of a terminal, the terminal containing hardware, the device comprising:

• a processor;
• a memory;
• a plurality of function modules;
• and a data management module, wherein:
• the function modules are configured to:
• receive a relation condition list and a corresponding random probability generator set by the data management module;
• determine whether to start recording data, and whether to end data recording operation in accordance with the relation condition list or the random probability generator, during operation process;
• and
• send respective data packets obtained by recording to the data management module by means of hardware contained in the terminal after the data recording operation is ended;
• and
• the data management module is configured to:
• set several or all function modules of the plurality of function modules as the monitored function modules according to a monitoring requirement;
• set the relation condition list for triggering recording among the monitored function modules;
• set the corresponding random probability generator for each function module of the monitored function modules;
• send the setting results to each function module of the monitored function modules;
• and
• store the data packets sent by each function module of the monitored function modules;
• wherein the relation condition list represents the triggering relation among the function modules of the terminal, comprising:
• as long as one function module of the monitored function modules is in a recording state, the other function modules of the monitored function modules are triggered to start recording data, the first one of the monitored function modules, which starts performing the recording operation, initiates recording in dependence on the random probability generator, and the other function modules of the monitored function modules initiate recording sequentially or simultaneously in dependence on the relation condition list;
• wherein the data management module is the result of execution on the processor of software stored in the memory;
• wherein the monitored function modules comprise:
• a liquid crystal display module, a downlink speech frame data processing module, an uplink speech frame data processing module and a call control module.
