Block access to IMSI in RAN side

[wireless_man]

Hi experts,

Anyone know if it is possible to block access to an IMSI (o a range of this) in the RNC (in the access network side, not in HLR)???

anyone knows a Huawei feature that performs this?

Thank you for your support.

Hi, In the RNC is not posible to block IMSI ranges. You can do it in the MSC-S or SGSN.

Cannot be..since if they let this feature,it can be used illegally..
