A METHOD AND SYSTEM FOR CHARGING IN ROAMING

摘要

The present invention discloses a method for implementing roaming charging, including: a proxy CRF is configured in the PLMN; a terminal uses bearer resources or packet data services in the currently visited PLMN to provide information for selecting charging rules for the home CRF through the proxy CRF in the PLMN, the home CRF selects the charging rules according to the information and provides the charging rules for the TPF serving the current terminal. The present invention also provides a system for implementing roaming charging, which includes a TPF, a home CRF in the terminal's home PLMN and a proxy CRF in the PLMN other than the terminal's home PLMN. When the terminal is roaming and utilizing the bearer resources or packet data services in the currently visited PLMN, the problem of addressing among the functions when implementing the data flow based charging procedure based on FBC mechanism is solved.
