Method for reporting radio link failure information

摘要

The present invention discloses a method for reporting RLF information. By sending the RLF report to an access system to which a cell which lead to a problem belongs to, the present invention can avoid unnecessary impact to other RAT to the maximum, guarantees that a problem of a RAT is solved in the RAT, and can detect a reason of radio link failure or handover failure correctly, reduces signaling interaction between different RATs, and simplifies the whole process of self-optimization, enhances performance of mobile communication system.

1. A method for reporting radio link failure (RLF) information, the method comprising:
identifying, by a user equipment (UE), a failure occurring on the UE, wherein the failure comprises RLF or handover failure; determining an access system for transmitting a RLF report based on a time interval from receiving a handover command message of a previous inter radio access technology (Inter-RAT) handover to the failure; transmitting, by the UE, the RLF report to a source access system of previous Inter-RAT handover if the interval is less than or equal to a predefined period of time; and transmitting, by the UE, the RLF report to a target access system of the previous Inter-RAT handover if the interval is greater than the predefined period of time.
