General Packet Radio Service (GPRS) Release 16.0.A PL1 (Build 10106 64-bit)OPNET Model Library 10.0 (24-7-2013) The General Packet Radio Service (GPRS) model captures the signaling and transmission behavior of a GPRS network. The model employs the following network components: Mobile Station (MS), Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN), Home Location Register (HLR), and a sink. The following simplifications to the GPRS standards specifications were made: no implementation of the base station sub-system (BSS), simplified allocation of MS identifiers, single active data session per MS, uni-directional user data transfer, and implementation of a single GGSN where all MS user data are tunneled through.
