Question: In a GPRS network with Flow Based Charging deployed, what is the expected behavior of charging functions in the SGSN/S-GW when they are in the same network as the GGSN?
Option 1: Charging functions in the SGSN/S-GW are always disabled to avoid redundancy.
Option 2: Charging functions in the SGSN/S-GW remain enabled for all scenarios, including intra-operator charging.
Option 3: The operator may decide to disable charging functions in the SGSN/S-GW, but they must still be used for inter-operator accounting purposes if in different networks.
Option 4: Charging functions in the SGSN/S-GW are only enabled during peak hours to handle increased traffic.
Explanation: When Flow Based Charging is deployed and the SGSN/S-GW and GGSN are in the same network, the operator has the flexibility to disable charging functions in the SGSN/S-GW for intra-operator charging purposes. However, these functions are still expected to be utilized for inter-operator accounting scenarios where the SGSN/S-GW and GGSN reside in different networks, ensuring seamless billing and revenue settlement between operators. This highlights the importance of adaptable charging architectures in supporting both operational efficiency and collaborative business models within the telecommunications sector.
