Method and device for roaming charging for CS fallback MTRF call
A method and device for charging roaming for CS fallback MTRF call is provided. At least one charging data record is obtained through receiving charging data records from at least one roaming charging device, wherein the user equipment roams to a VPLMN corresponding to the at least one roaming charging device. Based on the at least one charging data record and in combination with the local charging data record in the home charging device, consolidation processing is performed so as to obtain a consolidated target charging data record. A method of computing charging data records so as to perform final charging in a home charging device in the home network is introduced, instead of performing final charging in a roaming charging device in a visited network, which avoids repetitive charging on the charging data records in the mobile switching center of the visited network.
