A method for processing a radio link failure report, comprising: generating (101, 301), 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 is used for indicating 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 is used for indicating 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 is used for indicating 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 is used for indicating 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 (102, 302) the radio link failure report; wherein the A2 event refers to an event meeting the following conditions of a serving cell: when the sum of the measurement result of the serving cell and the hysteresis is smaller than an A2 threshold, it indicates that the A2 event occurs. generating (101, 301), 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 is used for indicating 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 is used for indicating 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 is used for indicating 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 is used for indicating 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 (102, 302) the radio link failure report; wherein the A2 event refers to an event meeting the following conditions of a serving cell: when the sum of the measurement result of the serving cell and the hysteresis is smaller than an A2 threshold, it indicates that the A2 event occurs.
