Abstract
A system of a wireless telecommunications network performs a process initiated in response to an indication of a chargeable event (e.g., a registration procedure). The system obtains a current location of the wireless device, determines that the current location is different from a home location, and queries a database of a home charging function (CHF) for charging information of a subscriber associated with the wireless device. The system then dynamically stores the charging information at a database of a local CHF thereby eliminating the need to check with the home CHF when responding to every subsequent chargeable event, which reduces the service latency otherwise experienced by the wireless device.
