Claim:
1. A network optimization system, wherein the system comprises a radio resource management functional entity, a distributed optimization functional entity, and a centralized optimization functional entity, wherein the radio resource management functional entity is configured to determine radio resource statistical data that is based on a transmission time interval (TTI) time granularity, and send the radio resource statistical data to the distributed optimization functional entity; the distributed optimization functional entity is configured to receive the radio resource statistical data sent by the radio resource management functional entity, determine, according to the radio resource statistical data, first statistical data that is based on a first time granularity, acquire characteristic information of the radio resource management functional entity, determine first reference configuration information and a first key performance index (KPI) according to the characteristic information of the radio resource management functional entity, determine association statistical data that is based on the first time granularity and that is associated with a second KPI, determine, according to first time granularity data and the first reference configuration information, a first optimization plan that corresponds to the first KPI, optimize the first KPI according to the first optimization plan, and send the first time granularity data to the centralized optimization functional entity, wherein the first time granularity data comprises the first statistical data and the association statistical data; and the centralized optimization functional entity is configured to receive the first time granularity data sent by the distributed optimization functional entity, determine, according to the first time granularity data, second statistical data that is based on a second time granularity, determine, according to the second statistical data, a second optimization plan that corresponds to the second KPI, and optimize the second KPI according to the second optimization plan, wherein the second time granularity is greater than the first time granularity.
