This capability would
allow the operator to determine where each CDR type is to be sent, and eventually send
all CDRs to the same platform once the transition is complete.
Trying to manage these functions at each individual network entity is a monstrous
task, requiring configuration at many different systems. This is simply not feasible during
large migrations and would only result in more cost to the operator.
The CGF sends CDRs to the billing system either via ???push??? or ???pull??? mechanisms,
depending on provisioning by the operator. This will depend on the network itself, the
billing system and its capabilities, and how the operator wants to manage the transport
for billing records. For example the operator may want to let the billing system pull
CDRs from the CGF based on a time schedule, providing more control over the receipt
of CDRs from multiple CGFs in the network and preventing congestion.
This function, like the CDF can be integrated within the same network element as
the CDF, or it may be a stand-alone function. Figure 7.4 illustrates the various options
available for implementing these two functions.

The various implementation options present an opportunity for operators to change
the current model used in their billing processes to meet the needs of other processes.
One interesting prospect can be seen in option 3 in Figure 7.
