System, software and method for implementing an integrated, device independent, packet telephony framework software solution
View Patent ↗A framework system serves to translate calls between dissimilar networks. More specifically, the framework system serves to translate calls between dissimilar packet networks and/or between a packet switch network and the public switched telephone network. The system includes a media engine module for terminating and handling channels of data transmitted between the networks in real time. An administrator module provides control and management interfaces for controlling processing applied to each channel. A conduit module serves to enable the distribution of software throughout the framework system allowing the distributed software to use interprocessor communication mechanism in the system. Optionally, a signaling engine module serves to provide access to call control information for connection between two networks.
1. A framework system embodied in a computer-readable medium that when executed by one or more processors translates calls between dissimilar networks, comprising:
a media engine module for terminating and handling channeling of data transmitted between dissimilar networks in real time, the media engine module comprising a data manager that when executed terminates data channels;
an administrator module providing control and management interfaces for controlling processing applied to each channel of data by said media engine module; and
a conduit module for enabling the distribution of the media engine and administrator modules throughout the framework system, allowing the distributed media engine and administrator modules to use interprocessor communication mechanisms used in the framework system.
2. The system of claim 1 , further comprising a signaling engine module that when executed provides access to call control information for connection between a circuit switched network and a packet network.
3. The system of claim 1 , wherein said media engine module is configured to transcode call information.
4. The system of claim 1 , wherein when said data manager is executed both packet and circuit switched data channels are terminated.
5. The system of claim 1 , wherein said data manager comprises an interface that when executed communicates with packet and circuit switched physical interfaces.
6. The system of claim 1 , wherein the media engine module further comprises a scheduler module for receiving input data for all channels from the data manager, receiving commands from the administrator module and modifying channel configuration based on received commands, processing input data for each channel and generating required output data, receiving output data for each channel, packaging output data for transmission, transmitting output data using the data manager, receiving responses or events from each channel, and transmitting responses or events to the administrator.
7. The system of claim 1 , wherein a control interface comprises a C Application Programmers Interface (C — API), and said management interface comprises one of a C — API or a Simple Network Management Protocol (SNMP) interface.
8. The system of claim 7 , wherein said control interface and said management interfaces are open interfaces.
9. The system of claim 1 , wherein said media engine module is distributed to and executes on network processors and digital signal processors with a high-speed interconnect between the network processors and the digital signal processors.
10. The system of claim 1 , wherein said media engine module is executed by a digital signal processor having data termination capabilities.
11. The system of claim 1 , further comprising a plurality of media engine modules.
12. The system of claim 1 , wherein said media engine module further comprises a scheduler for creating and maintaining the operation and data flow for channels under control of the administrator module.
13. The system of claim 1 , wherein said media engine module further comprises a scheduler for creating and maintaining the operation and data flow for channels under control of the administrator module.
14. The system of claim 13 , wherein said scheduler invokes one or more functions in an algorithm library to carry out the desired media processing for each channel.
15. The system of claim 1 , wherein said media engine module further comprises an adaptive jitter buffer manager module for removing jitter from packet streams.
16. The system of claim 15 , wherein said adaptive jitter buffer manager module is part of the data manager.
17. The system of claim 2 , wherein said signaling engine module comprises a call control module for converting between call control commands, requests and events generated by a signaling protocol stack, and a defined set of messages communicated between the administrator module and the call control module.
18. The system of claim 1 , wherein said media engine module further comprises media translation and handling software modules making up a plurality of media processing algorithms, each algorithm having a common interface which is open in nature.
19. The system of claim 2 , wherein said signaling engine module comprises an interface for accessing signaling protocol stacks.
