    Default CSFB re enter time 3G to 4G Nokia vs Huawei

    Dear experts,

    Comparing re enter time to 4G after CSFB for Huawei and Nokia in my network

    Huawei : 1s to 2s at most
    Nokia : 8s to 10s !!

    Smart layering is activated in my case

    Please to share re enter time for your networks.

    Any proposal to get better results with Nokia ?

    Many thanks

    Hi,

    It is a little tricky issue . Few things you need to clarify and double check listed below:

    1. For which service you re checking RwR (Fast Return to LTE) . Your test is based on CS Call , USSD, Incomplete CS call, PS Call , etc
    2. What phone model you are using while doing the benchmarking ? iPhone and Android behave differently for different vendors for RwR to 4G functionality !!
    3. Make sure fast return to LTE is activated and properly configured in Nokia region as 100% sure fast return to 4G is activated in your Huawei region that's why you have redirection in ~2sec but in Nokia normal reselection take place !

    4. There might be supplementary feature/configuration for fast return to LTE in Nokia region which may stop the RwR trigger to LTE in poor RF condition(E******* has optional coverage check criteria for RwR to LTE) hence user latch in 3G and doing normal selection after a while


    In case above did not answer to your problem let me know will guide you more how to troubleshoot the issue in more details
