  • Publication number: 20160249235
    Abstract: The present invention discloses a method for processing a radio link failure report, an apparatus, and a system. When a radio link failure occurs in user equipment in a current cell, if security information is activated, the user equipment initiates a radio resource control (RRC) connection re-establishment process. If a re-establishment cell is selected before a re-establishment timing times out, the user equipment sends an RRC connection re-establishment request to a network device, and records an identifier of the re-establishment cell in a radio link failure report. The user equipment sends the radio link failure report to the network device, so that the network device determines, according to the radio link failure report, a reason why a radio link failure occurs in the user equipment.
