Claim:
1. A method for processing a radio link failure report, comprising: generating, by a user equipment, a radio link failure report, wherein the radio link failure report carries an A2 event indication recorded by the user equipment, the A2 event indication is used for optimizing handover parameters between inter-frequency cells or inter-system cells, the A2 event indication indicates that the user equipment does not detect that a serving cell satisfies an inter-frequency A2 event or does not report an inter-frequency A2 event before occurrence of radio link failure (RLF); or the A2 event indication indicates that the user equipment detects that a serving cell satisfies an inter-frequency A2 event or has reported an inter-frequency A2 event before detecting RLF; or the A2 event indication indicates that the user equipment does not detect that a serving cell satisfies an inter-system A2 event or does not report an inter-system A2 event before detecting RLF; or the A2 event indication indicates that the user equipment detects that a serving cell satisfies an inter-system A2 event or has reported an inter-system A2 event before detecting RLF, and, the radio link failure report further carries cell information of an inter-system cell in which the user equipment selects to reside after encountering radio link failure (RLF), or cell information of an inter-system target cell for which the user equipment encounters handover failure (HOF), or cell information of an inter-system target cell for which the user equipment encounters HOF and cell information of an inter-system cell in which the user equipment resides after encountering the HOF; and reporting the radio link failure report; wherein, if the radio link failure report carries the cell information of the inter-system cell in which the user equipment selects to reside after encountering the radio link failure (RLF), the radio link failure report further carries: an RLF identifier, cell information of a cell from which a handover command is received by the user equipment for the last time, cell information of a cell in which the user equipment detects the RLF, reference signal receiving power (RSRP) values of a serving cell and a neighboring cell capable of being detected by the user equipment, and a second duration indication, wherein the second duration indication indicates a length of time between receiving the handover command and detecting the RLF by the user equipment; or, if the radio link failure report carries the cell information of the inter-system target cell for which the user equipment encounters the HOF, the radio link failure report further carries: an HOF identifier, RSRP values of a serving cell and a neighboring cell capable of being detected by the user equipment, cell information of a cell from which a handover command is received by the user equipment for the last time, and cell information of a reconstruction attempt cell of the user equipment; or, if the radio link failure report carries the cell information of the inter-system target cell for which the user equipment encounters the HOF and the cell information of the inter-system cell in which the user equipment resides after encountering the HOF, the radio link failure report further carries: an HOF identifier, cell information of a cell from which a handover command is received by the user equipment for the last time, and RSRP values of a serving cell and a neighboring cell capable of being detected by the user equipment.
