The main function of SGSN is to record the current location information of mobile station and complete the transmission and reception of mobile packet data between mobile station and GGSN. GGSN acts primarily as a gateway to many different data networks such as ISDN, PSPDN and LAN. GGSN is also called GPRS router;(GGSN can carry out protocol conversion on GPRS packet data in GSM network, so that these packet data can be transmitted to remote TCP/IP or X.25 network; in addition, some manufacturers have proposed the concept of GR(GSM Register, GPRS database). GR, similar to ILR in GSM, is a GPRS service database; it can exist independently or coexist with HLR, implemented through a server or SPC exchange.
