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
