8.8.2 General data amount
For GPRS, such as for all IP-based transmission methods, the user data of the application
are packed into a TCP/IP message and sent to the remote terminal (PUSH); the TCP/IP
stack of the remote terminal (e.g. Windows) must acknowledge each received TCP/IP
message.
With GPRS, all data accumulated by the user from the IP level (incoming and outgoing)
are calculated.
