Gf interface is used between SGSN and EIR to query the IMEI information if a MS tries to register with the network. It then sends back to the SGSN the result of the secondary PDP context creation with a negotiated QoS. To accommodate this the GPRS network architecture added new elements including the GGSN and SGSN to the existing GSM network to be able to accommodate this. The SGSN will compare the requested PDP type against the subscription data in the HLR, and will take a decision based on the following table, the GGSN should assign an IP address for every PDP created between the MS, and the GGSN.
