Reply To: Prepaid Systems Trafiic Engineering

Wallis Dudhnath

Hi Community,

Apologise for the late response to this question. In the past I used to
dimension and engineer Intelligent Network (IN) / PrePaid system (and solutions).

To help with dimensioning I would ask the following questions to prospective Communication Service Providers (CSPs):-

-BHCA for Mobile users
-Typical mErlang
-Number of Customers (e.g. 5 Million, 100 Million, etc..)
-Support for Voice Services using: CAMEL Phase 2, Phase 3 or Phase 4
-Requirements for any supported proprietary signalling in the Network
-Data Services using Gy / Gx / Sy / Diameter (Diameter Credit Control Application – DCCA)
-IP / Sigtran connectivity
-Complexity of Tariff Tables for Voice / Data Bundles
-Required Transaction for CAMEL signalling and Diameter during the Busy Hour
-Traffic rejected (e.g. new) once the IN / Prepaid exceeds 90%
-Convergent solution: Convergent Account – Prepaid / Postpaid / Hybrid configuration
-Activation or use of Optional Features (Vendor specific)
-Baremetal or Cloud solution (Linux, Openstack(), Docker(), etc..)
-Event Data Records (EDR) Processing during the Busy Hour
-Transactions for the IN / Prepaid administration solution
-IVR Transaction
-% of Traffic for Voice(MO, MT, CF, etc..), Data, SMS/USSD/etc.. Notification Services, Roaming, SMS/MMS, VoLTE/ViLTE, Voucher Updates (updates, status checks, etc..)
