Billing Interface for Roaming
Transferred Accounts Procedure (TAP) is the procedure that allows a visited network operator (VPMN) to provide billing records of roaming subscribers to their respective home network operator (HPMN). This enables both retail billing of the roaming subscriber, and wholesale settlement between the Parties. TAP3 is the latest version of the billing interface standard.
To support exchange of “invoicing quality” roaming call events, the Returned Accounts Procedure (RAP) was introduced in 2001 providing an automated and standardised method for handling errors on this interface.
Access to the current version of the TAP and RAP specification documents can be gained by completing the required information.
Fraud Prevention Interface for Roaming
Near Real-Time Roaming Data Exchange (NRTRDE) interface enables operators to exchange roaming call information within 4 hours of the call completion. This near real time transfer of call information between the operator in the visited country and the subscriber’s home network, minimises the occurrences of roaming fraud.
RAEX (Roaming Agreement EXchange)
Provides operators with the ability to electronically exchange operational roaming data (RAEX OpData) and commercial roaming rate information (RAEX IOT) using a centralised tool. The tool enables members to create, validate and distribute roaming agreement information in this new format or use alternative solutions via the 3rd party API.
This enables mobile network operators & roaming hubs to automate and optimise their work flow when relationships are created or changed.
GSMA Standard Exchange Rate Tool (GSER)
The GSER tool provides official exchange rates for TAP exchange, SMS interworking, and financial settlement activities from 1 May 2016. The GSER tool is available via Member Gateway and provides fully operational and automated, BA.11 compliant standardised exchange rates. Members are no longer required to perform their own exchange rate calculations themselves. GSMA Members subscribed to the tool can receive automated delivery of monthly or daily exchange rate files and can also search historical data.
To access the GSER tool, your company needs to be a GSMA member, you need to have a Member Gateway account and you should be a member of GSER group on Member Gateway. In Member Gateway, you will find GSER under the Roaming tab in the navigation menu.
Invoice, Settlement and Payment Interfaces
Roaming Traffic Data Report (RTDR) provides a standard reporting mechanism into financial invoicing and settlement processes. This report enables parties not involved in data exchange access to information they need for financial settlement activities, like cash management, re-financing operations and treasury or invoice production and settlement.
Electronic Invoice Data (EID) interface reduces the need for paper exchange of invoices within the industry whilst increasing efficiency.
Payment Notification Report (PNR) eases the reconciliation of incoming payment amounts against the outstanding due amount(s) within the roaming settlement procedure. PNR minimizes the need for unnecessary clarifications between the involved parties, resulting in fewer unallocated payments and increased efficiency in cash flow management.
These standardised B2B interfaces support interoperable financial operations within the industry.
Mobile Money Transfer (MMT) APIs
Mobile Money Transfer APIs provide a set of web services that allow operators and service intermediaries to interconnect in a common and efficient manner to deliver international remittance.
