Gp Interface

When the GGSN (Gateway GPRS Support Node) and the SGSN (Serving GPRS Support Node) are located in different networks, they may be interconnected via the Gp interface. This interface provides similar functionality to that of the Gn interface, however it usually includes extra security functionality which is based on mutual agreements between operators.
