The call has user communications in asynchronous transfer mode cells and call signaling. A signaling processor receives the call signaling and processes the call signaling to determine a connection to a service platform. The signaling processor transports a processor control message designating the selected connection. An asynchronous transfer mode interworking unit receives the user communications from the communication device and the processor control message from the signaling processor. The asynchronous transfer mode interworking unit converts the user communications from the asynchronous transfer mode cells to a format compatible with the service platform and dynamically transports the user communications to the service platform in real time. The service platform processes the user communications. The reverse process can also take place with the dynamic transfer, in real time, of the processed user communications back to the communication device in asynchronous transfer mode cells that identify the connection to the communication device.

SUMMARY OF THE INVENTION The present invention comprises a system for providing services for a call from a first communication device in an asynchronous transfer mode format. The call has user communications and call signaling. The system comprises a service platform adapted to receive the user communications. The service platform applies an interactive application to the user communications to process the user communications. The system further comprises a signaling processor adapted to receive the call signaling from the first communication device and to process the call signaling to select a first connection to the service platform. The signaling processor transports a processor control message designating the selected first connection. The system also comprises an interworking unit adapted to receive the processor control message from the signaling processor and to receive the user communications from the first communication device. The interworking unit converts the user communications from the asynchronous transfer mode format to a format usable by the service platform and uses the processor control message to transport the converted user communications to the service platform.
Still further , the present invention is a method for connecting a call through an asynchronous transfer mode system to a service node. The call has user communications and call signaling. The method comprises transporting the call from a communication device, the user communications comprising asynchronous transfer mode cells. The method includes receiving the call signaling in a signaling processor and processing the call signaling to select one of a plurality of connections to the service node. A processor control message is transported from the signaling processor designating the selected connection. The user communications and the processor control message are received in an interworking unit. The method further comprises converting the user communications from the asynchronous transfer mode cells to a format usable by the service node and using the processor control message to route the user communications to the service node over the selected connection and processing the user communications in the service node.
The SONET and SDH protocols describe the physical media and protocols upon which the communication of ATM cells takes place. SONET includes optical transmission of optical carrier (OC) signals and electrical transmission of synchronous transport signals (STSs). SONET signals transmit at a base rate of 51.84 Mega-bits per second (Mbps) for optical carrier level one (OC-1) and synchronous transport signal level one (STS-1). Also transmitted are multiples thereof, such as an STS level three (STS-3) and an OC level three (OC-3) at rates of 155.52 Mbps and an STS level twelve (STS-12) and an OC level 12 (OC-12) at rates of 622.08 Mbps, and fractions thereof, such as a virtual tributary group (VTG) at a rate of 6.912 Mbps. SDH includes transmission of optical synchronous transport module (STM O) signals and electrical synchronous transport module (STM E) signals. SDH signals transmit at a base rate of 155.52 Mbps for synchronous transport module level one electrical and optical (STM-1 E/O). Also transmitted are multiples thereof, such as an STM level four electrical/optical (STM-4 E/O) at rates of 622.08 Mbps, and fractions thereof, such as a tributary unit group (TUG) is at a rate of 6.912 Mbps.
The service platform 112 receives both the user communications from the interworking unit 114 and the processor control message from the signaling processor 110. The service platform 112 uses the information in the processor control message to process the user communications using the selected interactive application. When the application has completed, the service platform 112 transmits the processing results to the signaling processor 110 and the processed user communications to the interworking unit 114 to be transported either back to the second communication device 108 or to another service platform or device (not shown). The processing results contain control messages and data that allows the signaling processor 10 to reroute the processed user communications to another service platform, to the second communication device 108, or to the first communication device 106.
As illustrated in the telecommunication system 102 of FIG. 3, a service platform system 104A may contain many elements. A first communication device 106 to and a second communication device 108 interact with the service platform system 104A. The service platform system 104A contains a signaling processor 110 and a service platform 112A.
The OC-M/STS-M interface 918 is operational to accept ATM cells from the AAL 916 and to transmit the ATM cells over the connection to the communication device 926. The OC-M/NSTS-M interface 918 may also accept ATM cells in the OC or STS format and transmit them to the AAL 916.
The AAL 916 comprises both a convergence sublayer and a segmentation and reassembly (SAR) sublayer. The AAL 916 is operational to accept call origination device information in the DS0 format from the DS0 interface 912 and to convert the call origination device information into ATM cells. AALs are known in the art and information about AALs is provided by International Telecommunications Union (ITU) document I.363, which is hereby incorporated fully herein by reference. An AAL for voice communication signals is described in U.S. patent application Ser. No. 08/395,745, which was filed on Feb. 28, 1995, and entitled �Cell Processing for Voice Transmission,� and which is incorporated herein by reference.
As discussed above, the ATM interworking mux 902 also handles calls in the opposite direction, that is, in the direction from the OC-M/STS-M interface 918 to the DS0 interface 912, including calls exiting from the DS1 interface 910, the DS3 interface 908, the OC-N/STS-N interface 906, and the ISDN/GR-303 interface 920. For this traffic, the VPI/VCI has been selected already and the traffic has been routed through the cross-connect (not shown). As a result, the AAL 916 only needs to identify the pre-assigned DS0 for the selected VPI/VCI. This can be accomplished through a look-up table. In alternative embodiments, the signaling processor 922 can provide this DS0-VPI/VCI assignment through the control interface 904 to the AAL 916.
E0 connections are bi-directional and ATM connections typically are uni-directional. As a result, two virtual connections in opposing directions typically will be required for each E0. Those skilled in the art will appreciate how this can be accomplished in the context of the invention. For example, the cross-connect can be provisioned with a second set of VPI/VCIs in the opposite direction as the original set of VPI/VCIs. For each call, ATM interworking multiplexers would be configured to automatically invoke this second VPI/VCI to provide a bi-directional virtual connection to match the bidirectional E0 on the call.
