Communication networks and methods are disclosed for performing local roaming charging in LTE/EPC networks. A visited On-line Charging System (OCS) in the LTE/EPC network receives a credit request from a network element in a visited network that has been requested to provide a service to a roaming mobile device. In response to the credit request, the visited OCS determines a local rating for the service based on a local tariff defined by the operator of the visited network. The visited OCS grants a quota of service units to the network element based on the local rating, and transmits a credit response to the network element indicating the granted quota.
