The invention relates to a method for improving IMSI (International Mobile Subscriber Identity) backfill rate and accuracy of network monitoring and acquisition XDR (Extensible Data Rate), which comprises the following steps in monitoring and acquisition of 4G, 5G and 4/5G networks: when an acquisition side processes once at an S1-MME (Mobility Management Entity) or/and an N1N2 interface, preferentially sending an XDR record related to a cross-interface multi-interface association consistency rule; when the multi-interface association consistency rule takes effect preferentially, refreshing the GUTI backfill rule; when the multi-interface association consistency rule and the GUTI backfill rule take effect at the same time, user relation multi-interface consistency verification processing is added, and if the multi-interface association consistency rule and the GUTI backfill rule are not consistent, the multi-interface association consistency rule is preferentially used to refresh the GUTI backfill rule; and w
