Meaning
Technical reference document detailing the standard for data exchange and roaming connectivity between cellular network operators. Adherence to gsma prd aa.14 provides a uniform interface for billing and data transfer across international borders. It prevents discrepancies in data usage reporting between the visited and home networks.
The document specifically governs the exchange of roaming data records and does not cover the physical layer of the radio connection.
Connection Profile
Data exchange between operators requires a rigid structure to ensure that all session information is captured correctly. Each record contains the start time and duration of the session along with the volume of data consumed. This structured format allows disparate billing systems to communicate without manual intervention.
Settlement Procedure
Financial clearing between carriers depends on the accurate delivery of files as specified by the standard. If a file is missing or corrupted, the gsma prd aa.14 guidelines provide the framework for dispute resolution and re-transmission. This process ensures that the home operator pays the visited operator correctly for the resources used by the roaming subscriber.
Protocol Version
Updates to the reference document occur as new technologies like five-g are integrated into the roaming ecosystem. Each version maintains backward compatibility to ensure that legacy devices can still operate on foreign networks. Compliance with the latest version is typically a requirement for any new roaming agreement.
