Collecting CHRs

Collecting CHRs

Call History Records (CHRs) record key call information, such as the user number and call release reason. By collecting CHRs, you can respond to customer complaints quickly and perform real-time network monitoring, network running status analysis, and troubleshooting in a timely manner.

When collecting fault information, comply with local laws and the user privacy policies set down by carriers and take sufficient measures to ensure that personal data and other sensitive information are fully protected.

Configuring the USM

  1. Log in to the HUAWEI Operation & Maintenance System.
  2. Select CGP from the ME drop-down list box. The MML Command - CGP window is displayed.
  3. Check the CHR function configuration.


    %%LST CHRTRMCFG:;%%  
    RETCODE = 0  Operation succeeded  
    The result is as follows  
                CHR transmission switch  =  OFF  
               CHR offline collection flag  =  NO  
    CHR offline collection size  =  66 MB  
    (Number of results = 1)     

    By default, CHR transmission switch is set to OFF and CHR offline collection flag is set to NO. The system generates CHRs in the local directory /opt/HUAWEI/cgp/workshop/omu/share/export/pm/CHR of the OMU.

  4. Select USM from the ME drop-down list box. The MML Command - USM window is displayed.
  5. Configure the CHR output policy.

    Set key parameters as follows:

    • CHR output policy for register: Select FRF(First Register Failure), RRF(Refresh Register Failure), and LOF(Log-Off Failure).
    • CHR output policy for calls: Select FCDF(Failed call caused by devices) and FCUA(Failed call caused by user behaviors).
