A switched telephone network is arranged in a manner to enable packet voice communication between telephone terminals via multiple redundant packet switched networks. The packet switched networks may utilize different protocols, be operated by different entities, and have primary functions other than voice communication. One example of such a network may be internetworked networks, such as the Internet. One example of an alternate packet switched network may be a network whose primary function is control of a circuit switched telephone network. The common channel interoffice switching system (CCIS) of a public switched telephone network (PSTN) is a preferred example. A voice communication link may be established from telephone terminal to telephone terminal via the Internet, the quality of voice communication may be monitored, and the link may be transferred to the common channel interoffice signaling network if and when the quality of voice communication deteriorates beneath a pre-established norm. There is provided a means for monitoring the links of the common channel interoffice signaling system carrying the packetized voice communication and collecting the information needed to permit charging for the voice communication by time duration or by cells used to carry the packetized voice signal. The customer may be provided with the option of establishing the norm for diversion of the communication, or may elect which path is to be selected as the primary path.
A method of voice communication between two terminals including the steps of:
A method of voice communication between two terminals connected to a switched telephone network having a packet switched control network separate from said switched telephone network controlling operation of said switched telephone network, including the steps of:
A method of voice communication between two terminals connected to signal switching points of a switched telephone network having a packet switched control network separate from said switched telephone network connected to said signal switching points and controlling operation of said switched telephone network, including the steps of:
A communication system comprising in combination a switched telephone network having spaced switching systems connected to terminals, a packet switched control network controlling said switched telephone network, and a second packet switched network connectable to said switching systems, wherein said terminals are connected to said second packet switched network and subsequently to said control network via said switching systems for voice communication between said terminals via said packet switched networks.
A communication system comprising in combination a switched telephone network having spaced switching systems connected to terminals, a packet switched control network controlling said switched telephone network, and a second packet switched network connectable to said switching systems, wherein said terminals are connected sequentially to said packet switched networks for voice communication between said terminals via said packet switched networks.
A communication system comprising in combination a switched telephone network having spaced switching systems connected to terminals, a packet switched control network controlling said switched telephone network, and a second packet switched network connectable to said switching systems, wherein said terminals are linked sequentially to said packet switched networks via said switching systems for voice communication between said terminals via packetized voice signals over at least one of said packet switched networks.
A communication system comprising in combination a switched telephone network having spaced switching systems connected to terminals, a packet switched control network controlling said switched telephone network, and a second packet switched network connectable to said switching systems, wherein said terminals are linked to at least one of said packet switched networks via said switching systems for voice communication between said terminals over said at least one of said packet switched networks via packetized voice signals, and means for totalizing the units comprising said packetized voice signals over said at least one of said packet switched networks during said voice communication thereover.
