A charging server stores records corresponding to each of multiple subscriber identifiers associated with respective mobile devices. At least one record contains a counter value corresponding to one of multiple counter identifiers. The charging server receives a request from a policy server via a network, containing one of the subscriber identifiers and a session identifier. Responsive to receiving the request, the charging server determines whether the request includes any counter identifiers. When the request does not include any counter identifiers, the charging server determines whether the record corresponding to the received subscriber identifier contains any counter values. When the record includes at least one counter value, the charging server establishes a communications session with the policy server and transmits the at least one counter value to the policy server. When the record does not include any counter values, the charging server establishes a communications session with the policy server. |
