Abstract:
The apparatus and method are fast network SIP/SDP (Session Initiation Protocol/Session Description Protocol) procedures for conference operations upon request from end user with optimization of network resources. The apparatus has an SIP/SDP based network controller that, upon a received request, joins first and second calls into a conference call with at least a third call. The SIP/SDP based network controller is structured to negotiate, allocate and re-configure network resources.
Abstract:
A communication device (200) is described that includes a POTS interface system (204), a processing system (206), a conversion system (210), a voice interface system (212), and a digital interface system (202). When in operation, the POTS interface system receives analog voice signals for a call. The POTS interface system converts the analog voice signals from analog to digital to generate digital voice signals. The processing system performs an application on the digital voice signals to provide at least one presentation format of the digital voice signals of the call to a user. The conversion system then converts the digital voice signals into analog voice signals and a voice interface system transmits audible signals to the user. The digital interface system receives digital data signals from a data service provider and the processing system performs an application on the digital data signals to provide additional data to the user.
Abstract:
A system for providing statistical multiplexing of speech, other real-time data services and non-real-time data services for point to point and point to multipoint communications. The system has fast access and assignment procedures that allow the multiplexing of real-time, delay-critical data services with non-real-time data services. Continuity of periodic control channels across speech talkspurt and silence periods for conversational voice is maintained to carry signal measurement reports, channel quality feedback, and "comfort" noise information between different parts of the system.
