    Masked-IMEISV in Huawei MME

    Does anyone know how to configure Huawei MME to send Masked-IMEISV to eNode-B ?

    The Masked-IMEISV IE contains the IMEISV value with a mask, to identify a terminal model without identifying an individual Mobile Equipment.
    Reference: 36.413-e30

    Please check this configuration in MME:

    Set Compatibility of S1 Interface (SET S1CMPT)

    MSKIMEISVSCOPE: Masked IMEISV Sending Scope: This parameter is optional.
    This parameter specifies the sending scope of the Masked IMEISV IE in the Initial Context Setup Request and Handover Request messages that the MME sends to eNodeBs. Upon receiving the IE, an eNodeB can then perform IMEISV-based differentiated control on UEs.
    Data source: planned for the entire network
    Value:
    SPECENODEB(Specified eNodeBs)
    ALLENODEB(All eNodeBs)
    Initial value: SPECENODEB(Specified eNodeBs)
    Configuration notes: The Masked IMEISV IE is introduced in 3GPP Release 12. Huawei eNodeBs support the Masked IMEISV IE. The MME identifies Huawei eNodeB through Huawei proprietary messages Huawei eNodeBs send over the S1 interface. eNodeBs from other vendors may not be able to support this IE.
    If the MME is connected to some eNodeBs that do not support the Masked IMEISV IE, set this parameter to SPECENODEB(Specified eNodeBs). Then the MME sends this IE only to Huawei eNodeBs.
    If all eNodeBs connected to the MME support the Masked IMEISV IE, set this parameter to ALLENODEB(All eNodeBs). Then the MME sends this IE to all eNodeBs.
