US 8031761 B2Abstract
This application is a continuation-in-part of U.S. patent application Ser. No. 10/893,826 filed on Jul. 19, 2004 now U.S. Pat. No. 7,558,315, entitled ADAPTIVE MARGIN AND BAND CONTROL, which claims the benefit of priority under 35 U.S.C. �119(e) of U.S. Provisional Patent Application No. 60/527,853 filed on Dec. 7, 2003, entitled DYNAMIC MANAGEMENT OF COMMUNICATION SYSTEM, the disclosures of which are incorporated herein by reference in their entirety for all purposes.
The operational data may include historical data relating to prior performance of the DSL system. The historical data may be maintained in a database, library, etc. The operational data may further include data collected from the broader system in which the DSL system operates, for example from one or more MIBs or other data sources. The operational data may be sent to the controller by communication means internal and/or external to the DSL system itself. Some other types of operational data that can be evaluated include data pertaining to data rate, maximum attainable data rate, margin, code violations and Forward Error Correction (FEC) corrections of the DSL system and of its neighboring DSL systems. Additional operational data may include indications of modem capabilities or of modem features or of modem modes of operation. Modems may report such indications at various stages during DSL modem initialization such as “handshake” (as explained in the ITU-T recommendation G.994.1 or G.HS). Such indications may be provided during normal modem operation (“showtime”) via messages sent over the modem's embedded operations channel and reported to the network management systems or Spectrum Management Centers over interfaces such as defined in ITU-T Recommendation G.997.1 (also know as G.PLOAM). Alternately, modem capabilities for various modem types (identified by equipment manufacturer, chipset manufacturer, firmware version, serial number and others) may be known from databases, libraries, etc. The controlled parameters may have values that are chosen through known spectrum-balancing methods. In some embodiments such methods are advantageously executed infrequently, making use of all binder-level information that is available.
Embodiments of the present invention adaptively change the profiles of one or more DSL lines to reduce crosstalk noise and to improve DSL performance. A DSL line using a specified profile also can be said to be in a “state,” as is well known to those skilled in the art. Embodiments of the present invention control the transition of one or more DSL lines between profiles or states. The transitions are performed by evaluating the current state of the line relative to one or more target states. The possible target states (also referred to herein as proposed or target profiles, or “second” profiles) for a given current state (that is, a “first” profile) of a DSL line are defined through transition matrices. Such transition matrices may include prioritization of the target states for a given current state. Evaluation of the feasibility of staying in the current state or moving to one of the target states can be based on distributions of reported and estimated data distilled from operational data collected from the DSL system. Detailed descriptions of methods and systems for controlling profile transitions in DSL systems are given in U.S. Ser. No. 11/071,762, entitled DSL STATE AND LINE PROFILE CONTROL, filed Mar. 3, 2005, owned by ASSIA, Inc., which is incorporated by reference in its entirety for all purposes. The description herein discloses one or more examples of how profiles, transition matrices and transition rules can be designed to allow DSL lines to achieve reduced crosstalk and improved performance.
Good behavior for rate in either current state (“reported”) or target state (“estimated”);
Deployment information—In this case, binder-level information includes the characterization of a DSL line as being deployed from a CO, an RT, the SAI, and/or other points within the local loop topology. No information is available about distances between the CO, the RT, the SAI, or other points, or about the crosstalk coupling strength between lines.
Topology information—In addition to deployment information, topological information about the relative location of CO, RT, SAI or other deployment points may be available. Such information can comprise location information of such deployment points or approximate distances between such deployment points. Information about the neighborhood that the DSL line reaches may also be available. Neighborhood information may comprise an indication that lines in the neighborhood that the DSL line reaches are affected by certain kinds of noise sources (e.g. HDSL, SHDSL, radio-frequency interference). No information about crosstalk coupling strength between specified lines is available. Bridged-tap presence, location and length information may or may not be available.
Crosstalk coupling information—In addition to deployment and topology information, this case includes information about crosstalk interaction between DSL lines. Such crosstalk interaction information may comprise crosstalk coupling parameters, crosstalk strength characterization, crosstalk noise, etc.
940, 942—between profile 910 and profile 920; and
950, 952—between profile 920 and profile 930.
942—Profile 1 to Profile 2—CV=0 for 99% of time, rate at profile 1.gtoreq.target rate for 99% of time, estimated rate at profile 2.gtoreq.target rate
940—Profile 2 to Profile 1—CV>10 for 5% of time, rate at profile 2<target rate for 5% of time, estimated rate at profile 1.gtoreq.target rate
952—Profile 2 to Profile 3—CV=0 for 99% of time, rate at profile 2.gtoreq.target rate for 99% of time, estimated rate at profile 3.gtoreq.target rate
950—Profile 3 to Profile 2—CV>10 for 5% of time, rate at profile 3<target rate for 5% of time, estimated rate at profile 2.gtoreq.target rate
When topology information also is available, the above-described techniques for identifying and using profiles, transition matrices and transition rules can be enhanced to take into account such information. The same principles identified above—placing more emphasis on the higher frequencies for downstream DSL transmission from the RT point and placing more emphasis on the lower frequencies for downstream DSL transmission from the CO point—can still be applied, but the additional distance and loop length information available in topology information can help to improve profiles by using real conditions rather than assumed worst-case conditions. Also, for upstream DSL transmission (for example, for VDSL1 and VDSL2), profiles with different upstream power back-off or power spectral density, possibly with band preference (or margin cap mode) on or off, configurations can be used depending on topological knowledge such as the length of neighboring loops.
