The invention discloses a junk file searching method and terminal. The method comprises the steps: establishing a folder path table, wherein the folder path table is used for recording the path of all folders and the modification time thereof; detecting whether the modification time of the folder changes compared with that of the last scanning; reading the path of the folder from the folder path table and scanning the junk file under the path, if the modification time of the folder changes compared with that of the last scanning. According to the junk file searching method and terminal, the junk file in the modified folder can only be scanned, and the differential scanning is realized; the unmodified folder is no longer judged whether there is any junk file, and the repeated scanning is avoided, thus the purpose of increasing the scanning speed is achieved.

The invention provides a data quality monitoring method comprising the steps of (1) configuring monitoring rules: data quality monitoring rules are realized by means of a dispatching front end; (2) transmitting the monitoring rules: the monitoring rules are transmitted to a computing framework in a manner of configuration information by a dispatching system and the computing framework further transmits the rule information in a context manner; (3) identifying the monitoring rules; the computing framework acquires the monitoring rules through the context information and tacitly approves that the configuration information starting with a ruler character string is used as the configuration of the data quality monitoring rules, and the computing framework applies the monitoring rules to each line of to-be-produced data, judges whether each line of data meets the monitoring rules and performs statistical counting on lines of data meeting the monitoring rules; (4) outputting monitoring data: when data production is over, the data quality monitoring data is output in a counter manner. The invention also provides a data quality monitoring system.

The invention discloses a cell selection method and a terminal. The method includes: acquiring access assistance information carried in a synchronization signal block on a first frequency point; wherein, the access assistance information includes indicating the next second frequency to be scanned. point indication information; determine whether to scan the second frequency point according to the access assistance information and frequency point scanning history information. The terminal of the present invention preferentially scans the access assistance information to determine the next second frequency point to be scanned, because the second frequency point indicated by the access assistance information is recommended by the network device and has a high probability of being suitable for accessing the cell. Therefore, the efficiency of the terminal in selecting a cell can be improved, and the power consumption of the terminal can be reduced. In addition, the terminal also determines whether to scan the second frequency point based on the historical information of the frequency point, which can avoid the terminal repeatedly scanning the scanned frequency points and cells, and further reduce the time delay and consumption in the terminal search, cell selection, and reselection processes.
