    Hi Team,

    We have a requirement to get the current network mode for a GSM service  from Charging system.  Currently we have concept called budget control where postpaid customer who is subscribed to a postpaid package can have a dedicated prepaid account created in charging system and he can refill/credit balance for prepaid dedicated account (kind of wallet). Based on the context, he can switch the mode i.e., if he want to call for personal reason, he can avail prepaid dedicated account (wallet) balance and switch back to postpaid(original subscription mode) and can be charging during bill cycle if he is in postpaid. We wanted to get the current mode which he is using (prepaid/postpaid). Could you please which TMF api can fit to this. 

    I dont think product inventory can fit as we dont have logical product associated to dedicated account and we are getting this from charging system.

    Maybe TMF654 - Prepay Balance Management or TMF638 - Service Inventory
    although I don't think TMF654 has a "network mode".
    "network mode" confuses me a bit because what you describe is not related to the network but more like a "Charging Mode" (prepaid/postpaid)

    It sounds like a "calling card" application.  It sounds like your use case could be handled by prepending a dialed number with a code to indicate personal use. The MSC/IMS would need to understand the use of the code(s), stripping the code from the dialed digits to derive the destination address. DIAMETER credit control requests from CS/IMS should provide both the dialed digits (Requested-Party-Address) and destination number (Called-Party-Address) and the OCS would understand the code(s) and perform rating and charging appropriately.
