Backfilling method and communication monitoring system of the invention provides an application to the 3G network number, the number of backfill methods include: business process monitoring default on the IU-CS interface of UE, obtain UE carrying signaling presupposition in business process IMSI, initial TMSI, initial position code, available TMSI and lac ocationareacode; judge UE IMSI memory mapping and TMSI mapping; when the storage of UE IMSI and TMSI, the mapping of available TMSI and lac ocationareacode replace UE in TMSI and lac ocationareacode; when the mapping between IMSI and UE is not stored in TMSI, IMSI and TMSI to generate UE mapping and storage; monitoring the IU-CS interface on the UE shutdown process, obtaining UE carrying signaling in TMSI and shutdown process according to UE lac ocationareacode; carry off process in TMSI signaling and lac ocationareacode, Query the mapping relationship between IMSI's UE and TMSI to determine the IMSI of UE. When monitoring the shutdown process of the UE on the IU-CS interface, the invention can determine the true identity of the UE.
