Patent number: 5710807Abstract: In a telecommunications call a different charge is incurred for intervals of noncommunication than for intervals during which communication may take place. For example, a period of hold is one during which the party on hold cannot communicate with the other end of a connection. Such intervals are accumulated for a call and the charge for the call is adjusted in accordance with the total length of the noncommunicating intervals. Advantageously customers are charged primarily for the period of time during which they can actually communicate, without having to disconnect and later reestablish a call.Type: GrantFiled: June 17, 1996Date of Patent: January 20, 1998Assignee: Lucent Technologies Inc.Inventor: David B.
