GTPv0/v1 policy filtering
GTPv0/v1 policy filtering (called Advanced filtering on the GTP profile GUI) supports filtering GTPv0/v1 traffic based on RAT, RAI, ULI, APN restriction, and IMEI-SV to block specific harmful GPRS traffic and GPRS roaming traffic. The following table shows some of the GTP context requests and responses that are supported.
| GTP Create PDP Context Request | GTP Create PDP Context Response | GTP Update PDP Context Request | GTP Update PDP Context Response |
