GTPv2 policy filtering

GTPv2 policy filtering supports filtering GTPv2 traffic based on RAT, RAI, ULI, APN restriction, and IMEI-SV to block specific harmful GPRS traffic and GPRS roaming traffic.

GTPv2 policy filtering allows you to select one or more GTPv2 context request types and then add options to the GTP policy that can be matched with the selected request types. You also set the action to determine if the policy allows or denies traffic that matches the policy.

• APN

• APN Restriction

• RAT Type
