GPRS - Network Processes


Advertisements


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.
