name: GGSN
full_form: Gateway GPRS Support Node
context: The interworking point is at the Gi reference point. The GGSN for interworking with the ISP/PDN is the access point of the Packet Domain (see figure 13). The GGSN will either terminate the PPP connection towards the MS or may further relay PPP frames to the PDN. The PPP frames may be tunnelled in e.g. L2TP. Figure 13: The protocol stacks for the Gi PPP reference point In case the external PDN is an IP based network and the GGSN terminates PPP the same description applies as specified in subclause 11.2. In case the GGSN tunnels PPP frames to the PDN, the GGSN may behave like a LAC towards the external network.
description: The Gateway GPRS Support Node (GGSN) is a critical component in the General Packet Radio Service (GPRS) network, serving as an interworking point between the mobile network and external packet data networks (PDNs). It acts as an access point for the Packet Domain, facilitating communication between the mobile station (MS) and the PDN. The GGSN can either terminate PPP connections towards the MS or relay PPP frames to the PDN, potentially tunneling them using protocols like L2TP.
explanation: GGSN is classified as a Network Function because it plays a vital role in managing packet data transmission between the mobile network and external networks, aligning with the 3GPP's specifications for efficient interworking and communication.
