Method and system for routing calls as determined by a call cost database of a wireless transmit/receive unit

摘要

A method and communication system for routing calls. The system includes at least one wireless transmit/receive unit (WTRU), at least one wireless base station, a land-line communication unit, and a land-line base unit. A call placed by the land-line communication unit is routed to the wireless base station via the WTRU when a database in the WTRU indicates that it is less costly than routing the call via the land-line base unit. Alternatively, a call placed by the WTRU is routed to the land-line base station when the database indicates that it is less costly than routing the call via the wireless base station. The database stores wireless phone data, land-line data and preferred usage data provided by a user of the WTRU.
