SYSTEMS AND METHODS FOR HIERARCHICAL MOBILE POLICY CONTROL AND MOBILE POLICY ROAMING

摘要

A mobile policy hosting system (MPHS) includes a policy (PCRF) server, an SPR database, and a Billing-Conversion Server. The M PHS enables a mobile network to apply policies otherwise unsupported by the mobile network, thereby augmenting, expanding, or even fully replacing the existing policy services a mobile network. To interface with the M PHS, a new PCEF server is established in the mobile network. The PCRF server in the M PHS transmits a policy name to the new PCEF server in the mobile network so that it can enforce the policy with respect to a subscriber. The Billing-Conversion server converts all monetary information into universally quantifiable measurements (e.g., quantity of data, units of "time," etc.). This enables any mobile network to use the M PHS regardless of the local currency and regardless of the billing/charging interface.
