The invention discloses a method for collecting abnormal data of a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) wireless communication network user terminal. The method comprises the following steps: firstly, collecting key information of a wireless communication network at real time when a wireless communication network service is used by a user, thereby generating a data log file; comparing the collected network information with a built-in database so as to judge the network state; if the fact that the network is abnormal is detected, judging a reason and writing an abnormal reason and abnormal mobile phone signaling information into the data log file; automatically giving an uploading prompt and automatically uploading the log data onto an appointed back-stage management platform after being agreed by the user; and lastly managing and automatically analyzing the log data in the back-stage management platform. The method can be used for finding out abnormal phenomenon in daily service process based on a commercial terminal, more approaching to network use perception of an ordinary user, efficiently ensuring the consistency of user action and testing result as well as user perception, and more comprehensively estimating the property and the service quality of the whole network.
