  • Publication number: 20030003927
    Abstract: An audio calling name and calling number delivery method is disclosed. When a call is made from a calling party telephone to a called party telephone, a message is sent from an originating service switching point (SSP) associated with the calling party telephone to a terminating mobile switching center (MSC) associated with the wireless called party telephone. Typically, the message comprises the directory number of the calling party telephone. A wireless trigger is tripped at the terminating MSC and, in response, a query is sent to a service control point (SCP). A home location register (HLR) associated with the wireless telephone is queried to determine whether the wireless telephone is available. If the wireless telephone is available, then a name and a number associated with the calling party telephone is forwarded to a service node. The service node places a call to the wireless telephone and an audio annunciation of the name and the number is played to the called party.

  • Patent number: 5414385
    Abstract: A dual mode quadrature detector (15) uses the same components for both narrow band and wide band operation and provides an output amplitude which is independent of the mode of operation selected. A multiplier (32) provides a demodulated output signal (16) which is responsive to the phase difference between a signal (14) at one input (32A) and a phase shifted version of the signal at the other input (32B). A capacitor (30) and a phase shifting circuit (31) provide the phase shifted version of the signal. The phase shifting circuit (31) is responsive to a mode control signal (24) for determining the phase shift which is provided. The phase shift at the maximum frequency deviation of the narrow band signal is the same as the phase shaft at the maximum deviation of the wide band signal so that the output amplitude from the detector (15) is the same for both narrow band and wide band operation. The phase shift provided is controlled by varying the quality factor (Q) of the phase shifting circuit (31).
