- 1. Field of the Invention
- The invention is related to the field of communication systems, and in particular, to a system that provides data calls using both constant bit rate and variable bit rate connections.
- 2. Description of the Prior Art
- Telecommunication providers use broadband systems to carry data calls. Data calls are calls that are established to carry primarily data instead of voice. One example of a data call is a call originating from a computer through a modem for web surfing. Data calls can carry voice such as through a data call established for video conferencing.
- The broadband system must efficiently use the bandwidth for all types of calls to improve overall call performance. One prior solution determines the bandwidth on a call by call basis. FIG. 1 depicts a system level block diagram in an example of a prior solution. The prior solution is disclosed in a pending U.S. patent application Ser. No. 09/304,379, entitled “System and Method for Configuring Bandwidth Transmission Rates for Call Connections”, filed on May 4, 1999, which is hereby incorporated by reference. In FIG. 1, a
communication system 100 comprises acall processing system 130 and acall processing system 150. Thecall processing system 130 and thecall processing system 150 are disclosed in a pending U.S. patent application, entitled “System and Method for Processing a Call”, filed on Nov. 5, 1999, which is hereby incorporated by reference. Thecall processing system 130 comprises asignaling processor 132 and arouting system 134. Thecall processing system 150 comprises asignaling processor 152 and arouting system 154. Acommunication device 110 is connected to thesignaling processor 132 and therouting system 134. Thesignaling processor 132 is connected to therouting system 134 and thesignaling processor 152. Thesignaling processor 152 is connected to therouting system 154 and acommunication device 160. Thecommunication device 160 is connected to therouting system 154. Therouting system 154 is connected to therouting system 134. - FIG. 2 depicts a message sequence chart that depicts the operation of the
communication system 100 depicted in FIG. 1. To initiate a data call, thecommunication device 110 transmits an Initial Address Message (IAM) in Signaling System #7 (SS7) to thesignaling processor 132. Thesignaling processor 132 processes the IAM and determines the bandwidth for the call based on the IAM. Thesignaling processor 132 transfers the IAM to thesignaling processor 152. Thesignaling processor 132 generates and transmits a first control message identifying the bandwidth for the call to therouting system 134. - The
signaling processor 152 processes and transfers the IAM to thecommunication device 160. Thesignaling processor 152 generates and transmits a second control message to therouting system 154 based on the IAM. Subsequent SS7 signaling messages for call setup such as address complete messages are not shown for the sake of clarity. Therouting system 134 receives the call from thecommunication device 110. Therouting system 134 processes the first control message and routes the call to therouting system 154 based on the first control message. Therouting system 154 processes the second control message and routes the call to thecommunication device 160 based on the second control message. - The data call is made up of N×56K or N×64K connections between the
communication device 110 and therouting system 134. The N×56K or N×64K connections are identified by a session identification number. Between therouting system 134 and therouting system 154, the call uses one constant bit rate connection for each N×56K or N×64K connection for the duration of the call. - Typically, the actual bandwidth needed for the data call varies. One problem is the quality of the call is degraded when the actual bandwidth for the data call is greater than the allocated bandwidth. Another problem is unused allocated bandwidth is not utilized when the actual bandwidth is less than the allocated bandwidth. If the data call is not utilizing the unused allocated bandwidth, then this bandwidth could be utilized by other calls.
- Variable bit rate connections have been used for calls between asynchronous transfer mode (ATM) switches. The call uses only as much bandwidth as needed with the remaining bandwidth being allocated to other telecommunication services. Unfortunately, call processing systems do not effectively use both constant bit rate and variable bit rate connections for data calls.
- A processing system receives and processes telecommunication signaling for a user communication to determine a minimum bandwidth and a maximum bandwidth for the user communication. The processing system transfers control information indicating the minimum bandwidth and the maximum bandwidth for the user communication to a routing system. The routing system receives the control information and the user communication, and in response, transfers the user communication over a first communication path and a second communication path. The first communication path supports the minimum bandwidth, and the second communication path supports the maximum bandwidth.

- First Call Processing System and Second Call Processing System
- FIG. 3 depicts a system level block diagram in an example of the invention. A
communication device 300 is connected to a firstcall processing system 310 by afirst call link 302. The firstcall processing system 310 is connected to a secondcall processing system 320 by asecond call link 312. The secondcall processing system 320 is connected to acommunication device 330 by athird call link 322. - The
communication device 300 and thecommunication device 330 could be any device configured to exchange calls. Some examples of thecommunication device 300 and thecommunication device 330 are customer premises equipment (CPE), a service platform, a switch, and a remote digital terminal. CPE can be, for example, a telephone, a computer, a facsimile machine, or a private branch exchange. A service platform can be, for example, any enhanced computer platform that is capable of processing calls. A remote digital terminal is a device that concentrates analog twisted pairs from telephones and other like devices and converts the analog signals to a digital format known as GR-303. - The first
call processing system 310 could be any system that is configured to (1) receive signaling for the data call, (2) process the signaling to generate a first instruction to set up a constant bit rate connection for the data call between the firstcall processing system 310 and the secondcall processing system 320, and (3) process the signaling to generate a second instruction to set up a variable bit rate connection between the firstcall processing system 310 and the secondcall processing system 320. One example of the signaling for the call is an Initial Address Message (IAM). The LAM could be in Signaling System #7 (SS7) or C7. - The second
call processing system 320 could be any system that is configured to exchange calls with the firstcall processing system 310 through a constant bit rate connection and variable bit rate connections and exchange calls with thecommunication device 330. - In operation, the
communication device 300 transmits signaling for a data call to the firstcall processing system 310 to initiate the data call. The firstcall processing system 310 receives the signaling for the data call. The firstcall processing system 310 then processes the signaling to generates a first instruction to set up a constant bit rate connection for the data call between the firstcall processing system 310 and the secondcall processing system 320. The firstcall processing system 310 then processes the signaling to generate a second instruction to set up a variable bit rate connection between the firstcall processing system 310 and the secondcall processing system 320. The firstcall processing system 310 then extends the signaling for the data call to the secondcall processing system 320. The secondcall processing system 320 then extends the signaling for the data call to thecommunication device 330. Thecommunication device 300 transfers data to the firstcall processing system 310. The firstcall processing system 310 transfers data to the secondcall processing system 320 via the constant bit rate connection and the variable bit rate connection. The secondcall processing system 320 then transfers the data to thecommunication device 330. If desired, the first instruction and second instruction could be combined into one instruction. - Call Processing Systems with Signaling Processors and Routing Systems

- FIG. 4 depicts a system level block diagram of a
communication system 400 in an example of the invention. Thecommunication system 400 comprises acall processing system 430 and a call processing system 450. Thecall processing system 430 comprises asignaling processor 432 and arouting system 434. The call processing system 450 comprises asignaling processor 452 and arouting system 454. Acommunication device 110 is connected to thesignaling processor 432 and therouting system 434. The signalingprocessor 432 is connected to therouting system 434 and thesignaling processor 452. The signalingprocessor 452 is connected to therouting system 454 and acommunication device 160. Thecommunication device 160 is connected to therouting system 454. Therouting system 454 is connected to therouting system 434 via acall link 442. Thecall link 442 is comprised of a constantbit rate connection 444 and variablebit rate connections 446. - FIG. 5 depicts a message sequence chart for the operation of the
communication system 400 in an example of the invention. To initiate the call, thecommunication device 110 transmits an Initial Address Message (IAM) in Signaling System #7 (SS7) to thesignaling processor 432. The signalingprocessor 432 processes the IAM and identifies the call as a data call based on the information in the IAM. Because the call is a data call, the signalingprocessor 432 identifies the minimum rate based on the information in the IAM. In one embodiment of the invention, the minimum rate is based on the Bearer Capacity parameter of the IAM. The minimum rate is the lowest acceptable rate of data transfer for the data call. The signalingprocessor 432 determines the burst characteristics of the data call from the information in the IAM. The burst characteristics are the information associated with the maximum rate that the data call can achieve. The signalingprocessor 432 transfers the IAM to thesignaling processor 452. Based on the processing of the IAM, the signalingprocessor 432 then generates and transfers a first instruction to therouting system 434 to set up a constantbit rate connection 444 between therouting system 434 and therouting system 454 via thecall link 442. The first instruction indicates the minimum rate for the data call. Based on the processing of the IAM, the signalingprocessor 432 generates and transfers a second instruction to therouting system 434 to set up a variablebit rate connection 446 between therouting system 434 and therouting system 454 via thecall link 442 based on the processing of the IAM. - The
signaling processor 452 processes and transfers the IAM to thecommunication device 160. The signalingprocessor 452 then generates and transfers a control message to therouting system 454 to route the data call to thecommunication device 160 based on the processing of the IAM. Subsequent SS7 signaling messages related to call setup such as address complete messages are not shown for the sake of clarity. - The
routing system 434 then receives the data call from thecommunication device 110. The data call between thecommunication device 110 and therouting system 434 could be made up of N×56K or N×64K connections identified by a session identification number. Therouting system 434 processes the first instruction and sets up a constantbit rate connection 444 with therouting system 454 via thecall link 442 based on the first instruction. Therouting system 434 also routes the data call to therouting system 154 based on the first instruction. Therouting system 434 processes the second instruction and sets up the variablebit rate connection 446 with therouting system 454 via thecall link 442 based on the second instruction. The second instruction indicates the burst characteristics of the data call. Therouting system 454 processes the control message and routes the call to thecommunication device 160 based on the control message. - During the data call, the available bandwidth could be increased or decreased within the variable
bit rate connections 446. The signalingprocessor 432 generates a third instruction to therouting system 434 to alter thevariable rate connections 446 based on the capacity needed for the data call. Thus, the bandwidth for the data call can be optimized so performance of other calls could improve with increased bandwidth. - The above-described processor logic can be comprised of instructions that are stored on storage media. The instructions can be retrieved and executed by a processor. Some examples of instructions are software, program code, and firmware. Some examples of storage media are memory devices, tape, disks, integrated circuits, and servers. The instructions are operational when executed by the processor to direct the processor to operate in accord with the invention. Those skilled in the art are familiar with instructions, processor, and storage media.
- Those skilled in the art will appreciate variations of the above-described embodiments that fall within the scope of the invention. As a result, the invention is not limited to the specific examples and illustrations discussed above, but only by the following claims and their equivalents.
