Method and apparatus for reporting failure information
Provided are a method and apparatus for reporting failure information in a wireless communication system. A terminal may transmit a terminal capability information message including at least one of connection establishment failure (CEF) parameter information and radio link failure (RLF) parameter information. Further, the terminal may receive a terminal information request message requesting at least one of a CEF report and a RLF report, and transmit a terminal information response message including at least one of the CEF report and the RLF report.
1. A method for a terminal to operate in a wireless communication system, the method comprising:
transmitting a terminal capability information message including connection establishment failure (CEF) parameter information;
receiving a terminal information request message requesting a CEF report; and
transmitting a terminal information response message including the CEF report,
wherein the CEF parameter information indicates whether the terminal supports the CEF report in the terminal information response message,
the method further comprising:
selecting a cell; and
considering the cell as an acceptable cell based on barring exemption information,
wherein the barring exemption information is received through a system information block 1 (SIB1), and
wherein the barring exemption information indicates that the cell allows an emergency service.
2. The method of claim 1 , further comprising:
receiving a terminal capability enquiry message before transmitting the terminal capability information message.
3. The method of claim 2 , further comprising:
generating the CEF report after receiving the terminal information request message.
4. The method of claim 1 , wherein the CEF parameter information further indicates whether the terminal supports storage of CEF information or connection resume failure information.
5. A terminal in a wireless communication system comprising:
a processor configured to cause the terminal to:
transmit a terminal capability information message including connection establishment failure (CEF) parameter information;
receive a terminal information request message requesting a CEF report; and
transmit a terminal information response message including the CEF report,
wherein the CEF parameter information indicates whether the terminal supports the CEF report in the terminal information response message,
wherein the processor is further configured to cause the terminal to:
select a cell; and
consider the cell as an acceptable cell based on barring exemption information,
wherein the barring exemption information is received through a system information block 1 (SIB1), and
wherein the barring exemption information indicates that the cell allows an emergency service.
6. The terminal of claim 5 , wherein the processor is further configured to cause the terminal to:
receive a terminal capability enquiry message before transmitting the terminal capability information message.
7. The terminal of claim 6 , wherein the processor is further configured to cause the terminal to:
generate the CEF report after receiving the terminal information request message.
8. The terminal of claim 5 , wherein the CEF parameter information further indicates whether the terminal supports storage of CEF information or connection resume failure information.
