Claim:
1. A method for detecting network element (NE) load imbalance, comprising: performing gap analysis, according to a preset detecting strategy, on a NE performance indicator reported by a NE, and saving a result of the gap analysis in a network indicator buffer pool; regularly acquiring, from the network indicator buffer pool, the result of the gap analysis, and determining, according to the acquired result of the gap analysis, whether an inter-NE load imbalance exists; issuing a warning when determining that the inter-NE load imbalance exists, wherein the performing gap analysis, according to a preset detecting strategy, on a NE performance indicator reported by a NE comprises: determining, according to indicator information in a NE performance indicator buffer pool, whether a NE performance indicator set for any NE managed by a NE management system is complete; when the NE performance indicator set is complete, determining whether the NE performance indicator of each NE has exceeded a preset constraining absolute value threshold; when the NE performance indicator of each NE has exceeded a preset constraining absolute value threshold, computing, according to a load proportion and a NE performance indicator of a NE, an average load deviation, wherein the average load deviation P, as a benchmark for determining whether a NE performance indicator indicates overload of a NE, is computed according to P=ΣCi/ΣDi, with Ci being a current NE performance indicator, Di being a load proportion of a NE; computing, according to the average load deviation and a NE performance indicator of a NE, a load deviation percentage of the NE according to Vx=(Cx/Dx−P)*100/P, with Vx being the load deviation percentage of a NE, Cx being the current NE performance indicator, Dx being the load proportion of the NE, P being the average load deviation; comparing the load deviation percentage of a NE with a preset load percentage threshold; when the load deviation percentage of the NE exceeds the load percentage threshold, indicating a performance abnormality of the NE; when the load deviation percentage of the NE does not exceed the load percentage threshold, indicating a normal performance state of the NE.
