I am designing an application that once a subscriber sends a USSD requests, my application credits the DA with airtime worth a dollar. Then once the subscriber refills, I want to instantly debit the dollar from the subscriber’s MA. The problem I have so far is I have no way of knowing in real time when the subscriber has refilled his MA, and as such I have to depend on the periodic EMM dumps, which I analyze and extract the relevant refill info. My application then issues the debit instruction to the AIR server. Problem with this model is, between the delay of subscriber refilling and EMM dump, the user may use the dollar in their MA and I would thus never be sure when there is money and have to keep trying all the time to check. Two options I have explored so far are using PSO bits to suspend any activity on the MA until I debit the account, and using accumulators for the same. Does anyone know what I can do to know in real time when the subscriber has reloaded their account without depending on EMM dumps?17th April 2019 at 14:03 #62127Wallis DudhnathGuest
From your request you have a collection of Ericsson Charging_System nodes: AIR/AF, EMM, SDP,
CCN/OCC, etc.. AIR/AF will be used to “point” to the SDP that holds the Account: Main Account (MA) and the
associated Dedicated Accounts (DA) / Composite Accounts that can be used for “Offers”.
With Charging_System, Rating is performed by the AIR and SDP machines. With AIR, Rating rules can be
implemented for Advanced “Top-Ups”. Depending on the configured business rules the Main Account / Dedicated
Account(s) can be updated.
I see that you are already using the PSO (32bits) flag and the Accumulators (used for Bonus offers) to trigger
an Event / Action. One thought is to see if you can use the SDP with a Notification message to your application. If a Top-Up is succesful you can use the ACK message with a ESB. This can then be used to trigger
USSD Top-Up–AIR/AF–SDP–Notification (ACK)–ESB–Application
Another approach is to use a combination of AIR and SDP Event_Data_Records with
Online and File / Event Mediation (EMM OLM / F-E).
