8.8.2 General data amount

For GPRS, such as for all IP-based transmission methods, the user data of the ap-

plication 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 out-

going) are calculated.
