Method, device and system for processing radio link failure report and for statistically processing abnormal event

A method for statistically processing an abnormal event, comprising:

• receiving, by an access device, a radio link failure report;
• counting at least one radio link failure (RLF) event relevant to an A2 threshold according to an A2 event indication, if the radio link failure report carries the A2 event indication, wherein, if the A2 event indication indicates that a user equipment does not detect that a serving cell satisfies an inter-frequency A2 event before detecting RLF, occurrence of the at least one RLF event relevant to an inter-frequency A2 threshold is counted once;
• or, if the A2 event indication indicates that a user equipment does not detect that a serving cell satisfies an inter-system A2 event before detecting RLF, occurrence of the at least one RLF event relevant to an inter-system A2 threshold is counted once;
• and
• counting the number of abnormal cell handovers according to information carried in the radio link failure report, if the radio link failure report carries cell information of an inter-system cell in which a user equipment selects to reside after encountering radio link failure (RLF), or cell information of an inter-system target cell for which a user equipment encounters handover failure (HOF), or cell information of an inter-system target cell for which a user equipment encounters HOF and cell information of an inter-system cell in which the user equipment resides after encountering the HOF.

A user equipment, comprising:

• a generating unit, configured to generate 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 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
• a transmitter, configured to report the radio link failure report generated by the generating unit.

An access device, comprising:

• a receiver, configured to receive a radio link failure report;
• and
• a counting unit, configured to count radio link at least one failure (RLF) event relevant to an A2 threshold according to an A2 event indication, if the radio link failure report received by the receiver carries the A2 event indication, count occurrence of the at least one RLF event relevant to an inter-frequency A2 threshold is counted once if the A2 event indication indicates that a user equipment does not detect that a serving cell satisfies an inter-frequency A2 event before detecting RLF;
• or count occurrence of the at least one RLFevent relevant to an inter-system A2 threshold is counted once if the A2 event indication indicates that a user equipment does not detect that a serving cell satisfies an inter-system A2 event before detecting RLF;
• and,
• configured to count the number of abnormal cell handovers according to information carried in the radio link failure report, if the radio link failure report carries cell information of an inter-system cell in which a user equipment selects to reside after encountering radio link failure (RLF), or cell information of an inter-system target cell for which a user equipment encounters handover failure (HOF), or cell information of an inter-system target cell for which a user equipment encounters HOF and cell information of an inter-system cell in which the user equipment resides after encountering the HOF.
