GPRS - Network Processes

This chapter gives a brief description of the basic processes used in GPRS networks:

• Attach process - Process by which the MS attaches (i.e., connects) to the SGSN in a GPRS network.
• Authentication process - Process by which the SGSN authenticates the mobile subscriber.
• PDP activation process - Process by which a user session is established between the MS and the destination network.
• Detach process - Process by which the MS detaches (i.e., disconnects) from the SGSN in the GPRS network.
• Network-initiated PDP request for static IP address - Process by which a call from the packet data network reaches the MS using a static IP address.
• Network-initiated PDP request for dynamic IP address - Process by which a call from the packet data network reaches the MS using a dynamic IP address.
