SGSN (serving GPRS support node)

The GPRS network element that provides the direct customer interface. (Cingular)

The SGSN is the node which in some sense carries out the same function as the Foreign Agent in Mobile IP. However, an SGSN is actually considerably more complex since it also does the full set of interworking with the connected radio network. This means that the functions carried out by the SGSN vary quite considerably between GSM and UMTS. (Wikipedia)
