Switching telephone calls between wireline and cellular telephones |
摘要 |
A telephone subscriber having both a wireline and a cellular telephone can switch calls between these phones. A routing table identifies that a subscriber is entitled to this service, and a look up table maintains the telephone numbers of the two different telephones. Upon detection of a unique signal indicating a request for switching a call connected to one of the telephones to the other telephone, a connection is made to the other telephone, the two connections are bridged, and then the first connection is dropped. The routing table may be maintained in a central office and the look up table may be maintained in a mobile switching center or a fixed cellular mobility agent.
