CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of prior application Ser. No. 08/525,897, entitled "Broadband Telecommunications System", filed Sep. 8, 1995 U.S. Pat. No. 5,991,301, currently pending, and that is a continuation-in-part of prior application Ser. No. 08/238,605, entitled "Method, System, and Apparatus for Telecommunications Control", filed May 5, 1994, now abandoned.
BACKGROUND At present, Asynchronous Transfer Mode (ATM) technology is being developed to provide broadband switching capability for telecommunications calls. A call is a request for telecommunications services. Some ATM systems have used ATM cross-connects to provide virtual connections. Cross-connect devices do not have the capacity to process signaling. Signaling refers to messages that are used by telecommunications networks to set-up and tear down calls. Thus, ATM cross-connects cannot make connections on a call by call basis. As a result, connections through cross-connect systems must be pre-provisioned. They provide a relatively rigid switching fabric. Due to this limitation, ATM cross-connect systems have been primarily used to provide dedicated connections, such as permanent virtual circuits (PVCs) and permanent virtual paths (PVPs). But, they do not provide ATM switching on a call by call basis as required to provide switched virtual circuits (SVCs) or switched virtual paths (SVPs). Those skilled in the art are well aware of the efficiencies created by using SVPs and SVCs as opposed to PVCs and PVPs. SVCs and SVPs utilize bandwidth more efficiently.
SUMMARY The invention includes a method of operating a telecommunications system to provide a call with a virtual connection. The invention is applicable where a user places the call by sending signaling for the call to the telecommunications system and by transmitting user information to the telecommunications system over a particular connection for the call. The telecommunications system comprises an ATM interworking multiplexer and a signaling processor coupled to the ATM interworking multiplexer. The method comprises receiving the signaling for the call into the signaling processor and processing the signaling to select the virtual connection. The method further includes generating a control message in the signaling processor to identify the particular connection and the selected virtual connection, and transmitting the control message to the ATM interworking multiplexer. The method further includes receiving the user information for the call from the particular connection into the ATM interworking multiplexer and converting the user information into ATM cells that identify the selected virtual connection in response to the control message. The method further includes transmitting the ATM cells from the ATM interworking multiplexer over the selected virtual connection.
DETAILED DESCRIPTION For purposes of clarity, the term "connection" will be used to refer to the transmission media used to carry user traffic. The term "link" will be used to refer to the transmission media used to carry signaling or control messages. On the Figures, connections are shown by a single line and signaling links and data links are shown by double lines.
The ATM Interworking Multiplexer FIG. 3 shows one embodiment of the mux that is suitable for the present invention, but other muxes that support the requirements of the invention are also applicable. Shown are control interface 300, OC-3 interface 305, DS3 interface 310, DS1 interface 315, DS0 interface 320, digital signal processing (DSP) 325, AAL 330, and OC-12 interface 335.
The ATM Cross-Connect System FIG. 4 depicts virtual connections provided by the ATM cross-connect system in a version of the invention, although numerous other techniques for providing virtual connections will be appreciated by one skilled in the art, and the invention contemplates any such system. Shown are virtual connections 410, 412, 414, 416, 418, 420, 422, 424, and 426. These virtual connections are shown interconnecting muxes 1, 2, and 3 through cross-connects X and Y. Virtual connections are provisioned in between each mux. Each mux would have a virtual path provisioned through the cross-connect system to every mux. Additional virtual paths could be provisioned between two muxes using diverse physical routes for the sake of redundancy. These virtual paths are designated in the ATM cells by the VPI. The VPIs are designated locally by the cross-connects to be the destination mux. For example, connections 410, 416, and 424 are all designated as VP1 because they terminate at mux 1. Connections that terminate at mux 2 can be defined locally as VP2. On a call entering at mux 1, the NPA-NXX of the dialed number might be analyzed to select mux 2 as the terminating mux. As such the VPI used on the call would be VP2. From mux 1, VP2 connects to mux 2. The VCIs in VP2 would also be tracked and an available one would be selected. As an alternative to VPI provisioning between muxes, ranges of VCIs may be provisioned between muxes to add granularity below the VPI level.
Operation within a Network FIG. 5 depicts an embodiment of the invention with respect to a specific telecommunications network scenario, although the invention is not limited to this specific scenario. FIG. 5 shows telecommunications system 500. Shown are user 510, user 512, user 514, user 516, STP 518, STP 520, STP 522, STP 524, mux 526, mux 528, mux 530, mux 532, call/connection manager (CCM) 534, CCM 536, CCM 538, CCM 540, ATM cross-connect 542, ATM cross-connect 544, ATM cross-connect 546, and Service Control Point (SCP) 550. The CCMs are designated as "signaling processor" on FIG. 5. For clarity, the connections and signaling links are not numbered. Except for the SCP, all of these components are described above, and the CCMs are also discussed below. SCPs are well known in the art. An SCP is a processor and database that answers signaling queries to assist in call processing. An example is an "800" routing query between a switch and an SCP.
The Call/Connection Manager (CCM) FIGS. 6-12 refer to a preferred embodiment of the signaling processor, also known as the CCM, but any processor which supports the requirements stated for the invention would suffice. FIG. 6 depicts a signaling processor suitable for the invention. Signaling processor 600 would typically be separate from the mux, but those skilled in the art appreciate that they could be housed together and coupled in a bus arrangement instead of being coupled by a data or signaling link. Signaling processor 600 may support a single mux or support multiple muxes.
The Platform Handler Platform handler 620 is preferred, but is not required as its functions could be handled by MTP 610 and/or message handler 640. Platform handler 620 has massaging interfaces that exchange, buffer, dis-assemble, and re-assemble messages for MTP 610, bearer control 630, message handler 640, and record handler 650. Platform handler 620 could exchange these messages over an ethernet--TCP/IP interface, but any technique for transfer of messages is contemplated by the invention. Platform handler 620 could also check the messages for basic flaws. Should more than one message handler be connected to platform handler 620, ISUP messages could be allocated to the message handlers based on the SLS of the particular ISUP message. Platform handler 620 also accepts routing instructions from message handler 640 for routing certain ISUP messages to particular select call model processes of message handler 640.
The Message Handler FIG. 7 depicts a version of the message handler. External connections have been omitted for the sake of clarity. Message handler 700 is shown and includes ISUP 710, call manager 720, feature manager 730, switching manager 740, and SCF access manager 750. The primary function of message handler 700 is to process ISUP messages for calls, generate subsequent messages, and invoke services. As a result of its processing, message handler 700 is able to assign incoming access connections (CICs in SS7) to VPI/VCIs and instruct the mux to provide SVPs and SVCs through an ATM cross-connect system.
Bearer Control and the Record Handler The following discussion refers to both FIGS. 6 and 7. Depending on which call segment (originating or terminating) is being processed, the origination process or the termination process will check the user service information data and originating line information to assess the need for echo control. If the call is a data call, a message is sent to bearer control 630. Based on the CIC, bearer control 630 can select which echo canceller circuit needs to be disabled. A message will be generated to that effect and transmitted over a standard data link, such as UDP/IP, to the pertinent echo control system. If the echo canceller is remote, a T1 link may be desired for transport. As described above, echo control can be implemented by the multiplexer. Once a release (REL) message is received for the call, the echo canceller is re-enabled. On a typical call, this procedure will occur twice. Once for an echo canceller on the originating side of the call, and again for an echo canceller on the terminating side of the call. The CCM that handles the IAM for a particular call segment will control the particular echo cancellers for the segment. An example of an echo control system would be a Tellabs echo canceller controller with ethernet interfaces connected over an asynchronous bus to the echo cancellers. The echo cancellers could be integrated into the muxes.
Call Processing SS7 massaging is well known in the art. SS7 ISUP messages contain numerous fields of information. Each message will have a routing label containing a destination point code (DPC), an origination point code (OPC), and a signaling link selection (SLS) which are used primarily for routing the message. Each message contains a circuit identification code (CIC) which identifies the circuit to which the message relates. Each message contains the message type which is used to recognize the message. ISUP messages also contain mandatory parts filled with fixed length data and variable length data, in addition to a part available for optional data. These parts vary from message type to message type depending on the information needed.
