Abstract
In communication system (200), a packet data terminal (102) (e.g., personal computer (PC), personal digital assistant (PDA), telephone, mobile radiotelephone, network access device, Internet peripheral, and the like) initiates, coordinates, and controls the provision of on-demand conference call and call waiting services as a function of user inputs without the need for coordination of network resources that dominate conference call service as currently known and practiced. The packet data terminal permits users to establish call conference services for originating and terminating calls, alike. In addition, multi-party call waiting (two or more parties on-hold) services are established.
Claims17
A packet data terminal comprising:
- a digital-to-analog converter, for receiving a first packet data stream and a second packet data stream and converting the first packet data stream and the second packet data stream into a first analog representation and a second analog representation, respectively;
- and
- a selective mixer, coupled to the digital-to-analog converter, for selectively mixing the first analog representation and the second analog representation to provide one of a mixed and a non-mixed output.
In a telecommunications system that couples voice communication users, a packet data terminal comprising:
- a digital-to-analog converter that:
- receives a plurality of packet voice data streams, and
- converts each packet voice data stream of the plurality of packet voice data streams into a plurality of separate analog representations;
- a selective mixer, coupled to the digital-to-analog converter, that do selectively mixes the plurality of separate analog representations to provide one of a mixed and a non-mixed analog output;
- a mixer digitizer, operably coupled to the selective mixer, that:
- receives the one of the mixed and the non-mixed analog output from the selective mixer,
- mixes the one of the mixed and the non-mixed analog output with voice from a microphone to generate mixed voice, and
- converts the mixed voice into packet data;
- a multiplexer, coupled to the digital mixer, that distributes the packet data;
- and
- a call control module, coupled to the selective mixer and the multiplexer, wherein selective mixer output and packet data distribution are controlled by the call control module as a function of user election.
A method for establishing conference call service comprising the steps of:
- receiving, at a data terminal, a plurality of digital voice data streams, each digital voice data stream representing a separate call session;
- converting each digital voice data stream into a plurality of separate analog representations;
- selecting, from amongst the plurality of separate analog representations, the call sessions of interest;
- mixing the plurality of separate analog representations of the call sessions of interest, one with another, to produce a first mixed output;
- mixing the first mixed output, with user generated voice signals, to produce a second mixed output;
- converting the second mixed output into a packet data stream;
- and
- distributing the packet data to the call sessions of interest.
