And sequencing or de-duplication processing is performed on the disordered or repeated cell messages, so that the accuracy of the signaling flow is ensured. Further, a multi-backfill mechanism may be further configured, that is, when no process data of a certain process is currently identified, the process data of a subsequent process may be identified first, and when the process data of a previous process is identified in the process data of the subsequent process, the process data of the previous process may be backfilled based on the process data of the subsequent process.
And finally, transmitting the data generated by the different associated backfill modules to a data output module for formatting output through an inter-process communication mechanism. And the data output module carries out specific formatting processing on each single-interface data which is combined and synthesized and outputs the single-interface data.

And the fast and uniform shunt decoding is realized, and the decoding efficiency is improved. By means of the methods of collecting user identification, a repeated backfilling mechanism, data order preservation and the like, the associated backfilling rate is improved, and the data quality is improved. And the data of the whole network is comprehensively collected, so that more comprehensive data support is provided for other systems, and the macro understanding of the network operation condition and problem analysis is facilitated.
