Tariff charging method for calls from mobile subscribers in radio network

摘要

The method involves definition of e.g. a Home. Zone (HOZO), a City. Zone (CIZO) and an Office. Zone (OFZO) with corresponding tariffs (THZ,TCZ,TOZ) which are stored in a network database (IC) and in the charging equipment (BC) linked to the Mobile. Switching. Centre (MSC). These zones are defined as collections of radio cells and/or areas of residence for individual subscribers. Their definitions (CID,LAID) are sent with type-of-zone identifiers (ZID) to the mobile station (MS) for storage in its. Subscriber. Identity. Module (SIM).
