Patent number: 7978844Abstract: Systems and methods are disclosed which allow a person to pre-set preferred calling times for receiving incoming calls. During these pre-set times (which could vary from day to day) calls that arrive are interrupted such that ringing tone is not applied to at least some of the telephones at the user's premises. The caller is informed that the user prefers not to receive calls until the pre-set time. In one embodiment, the caller is given the option of leaving a message or, if the caller desires, completing the call. The system can be implemented by a call answer machine at the customer's premises while in another embodiment the interrupt occurs at a central switching point.Type: GrantFiled: December 16, 2005Date of Patent: July 12, 2011Assignee: Union Beach L.P.Inventor: David H.

Patent number: 6470406Abstract: In a heterogeneuos work environment a method and apparatus for managing isochronous streaming servers is disclosed. This includes a mechanism for allocating processor resource to streaming servers at admission control time with respect to the business importance of work they will be running. This mechanism includes a provision to preempt currently running streaming work of lesser business importance in order to allocate its share of the processor to the new higher importance work. Also included is a mechanism to resume the server when a running stream terminated and processor becomes available. In the case of the variable bit rate multiple peak problem a mechanism is presented to preempt running streaming work at the lowest business importance so that higher priority work can continue to run unaffected. The mechanism to resume paused streams at the termination of a stream also restarts this work.Type: GrantFiled: June 25, 1999Date of Patent: October 22, 2002Assignee: International Business Machines CorporationInventors: Donna Dillenberger, Stephen Heisig, Ingolf Salm, Robert Vaupel

Patent number: 6389131Abstract: A method and apparatus for establishing calls initiated by an initial call attempt request to permit the characteristics of call connections established in response to the ICA request to be controlled by translation information of a defining port. The defining port can be a real port of a switch, or a pseudo port having associated therewith a block of translation information, but no physical network equipment. Among the characteristics that can be controlled are a billing number of the call, and a routing plan for determining a route based on destination information specified in the ICA request, and the line or trunk features offered in the switch. Advantageously, the characteristics of the ICA request connection can be specified by translation information instead of being inflexibly tied to the pre-defined standard characteristics.Type: GrantFiled: September 28, 1998Date of Patent: May 14, 2002Assignee: Lucent Technologies Inc.Inventors: Marino K. Aquino, Barry W. Briggs, Ning-Yin Chou, Kathleen Dalbey

Patent number: 5452354Abstract: The present invention relates to a method for generating the ringing tone of a phone and apparatus according to the method. A ringing tone generator (12)is controlled according to a ringing tone sequence by control circuitry (13), and subscriber identification information is stored in a fixed or a detachably connectable nonvolatile memory (10) of the phone. When the phone is switched on, the microprocessor (13) reads from a subscriber identification information memory (10) of the phone at least some of the subscriber identification information, calculates on the basis thereof the values for ringing tone parameters (1, . . . ,6) describing the ringing tone sequence, and stores them in a ringing tone parameter memory (11). When receiving a page to the phone, the control circuitry (13) reads from the ringing tone parameter memory (11) the values of the parameters (1, . . . , 6) describing the ringing tone sequence, generates a ringing tone sequence on the basis of the parameter values (1, . . .Type: GrantFiled: December 13, 1993Date of Patent: September 19, 1995Assignee: Nokia Mobile Phones Ltd.Inventors: Tapio Kyronlahti, Heikki Rautila, Erkki Veikkolainen, Tommi Lunden
