The Gi point of interaction is the point of interaction among GPRS and outer parcel information organizations (in GPRS networks the GGSN and PDN interfaces – the Internet) and the mark of show of terminal IP addresses on outside information organizations. All 3GPP area terminal portability is taken care of before the Gi connection point, where exemplification/decapsulation of conventions, address interpretation (for example private organization IP locations to public organization IP addresses), distinguishing proof and validation of client access, and so on are required. As GPRS can uphold a wide scope of information organizations, the Gi point of interaction is certainly not a standard point of interaction, yet rather a reference point.

GPRS is interconnected with different public parcel organizations like the Internet or ISDN through the Gi connection point, and all client and control plane capacities are taken care of on top of the terminal IP layer. The Gi connection point requires convention exemplification/de-embodiment, address interpretation (for example private to public IP addresses), client access verification and validation. As GPRS can uphold a wide assortment of information organizations, the Gi is certainly not a standard point of interaction, yet rather a reference point.
Gn interface The Gn point of interaction is the connection point between SGSNs in a similar PLMN and among SGSNs and GGSNs as the Gn interface (between SGSNs in a GPRS organization). This interface convention upholds the transmission of client information and related flagging, upholds portability the board (MM) and the point of interaction utilizes the TCP/IP convention. gn gives the information and flagging point of interaction and in IP-based spine networks the Gn (and Gp) interface utilizes the GPRS Channel Protocol (GTP). the GPRS Tunneling Protocol (GTP) is utilized between the GSNs in the GPRS network for both Gp and Gn stages are characterized on the stage.
Gb interface The point of interaction between the SGSN and the BBS is the Gb interface (in a GPRS network the SGSN connects with the BSS). china GI fittings Through this interface the SGSN speaks with the BSS framework and the MS for bundle information transmission, portability the executives and meeting the board capacities. This point of interaction is a compulsory connection point for GPRS organizations. The point of interaction convention can be utilized to communicate flagging and traffic data. Traffic signal is given through Frame Relay-based network administrations, and the SGSN can speak with the BSS utilizing Frame Relay organizations or highlight point Frame Relay associations. It upholds versatility the board capacities and meeting capacities like GPRS connection/separation, security, steering, actuation/deactivation of information association data, and so on It additionally upholds the transmission of bundle information from the MS to the SGSN by means of the BSS.
