The GGSN replies with an affirmative Create PDP Context Response using GTPC. The response
will contain information elements such as the PDP Address representing either the static address
requested by the MS or the address assigned by the GGSN, the TEID used to reference PDP Address,
and PDP configuration options specified by the GGSN.

The GGSN delivers the GGSN Charging Detail Records (G-CDRs) to a charging gateway (CG)
using GTP Prime (GTPP). Note that, though not shown in this example, the GGSN could optionally
be configured to send partial CDRs while the PDP context is active.
