Abstract

Improved DSL and/or other communication system services can be provided by motivating users, service providers and operators to implement and comply with one or more operational conditions, such as parameter value limits and/or ranges, that enhance operation of the communication system. Enhanced operation can include providing a reward such as an operational benefit to one or more users and/or mitigating problems experienced by other users in the communication system, which can be one or more communication lines. A DSL line implementing and complying with one or more operational conditions is provided with a reward (such as an operational benefit like a higher maximum data rate), which is otherwise withheld if the line fails to comply with the condition(s). Each operational condition may be set and monitored by a controller, such as a DSL optimizer that collects and analyzes operational data to determine compliance. Other requirements may be imposed for a DSL line to be eligible for the reward, such as the requiring the DSL line to provide operational data to the controller and requiring the DSL line's acceptance of control signals from the controller. The controller can use the operational data and line control to enhance system operation, for example to reduce crosstalk between lines in a common binder.

In ADSL, the circuit of sharing same bundle stops on same Line cards or the same equipment that can adjust transmission, is unlikely like this, but to terminate in but be practicable among the VDSL to this same line an outpost of the tax office (same-line-card) bundle.Yet, can extend to ADSL to the discussion of xDSL system, this is owing to can take the common termination (particularly in the DSLAM of the renewal that can handle ADSL and VDSL) of same-binder lines.In the canonical topology of dsl device, the transceiver of some is to being in service and/or can utilizing, and the part of each local loop disposes with many loops to other users in the bundle (perhaps bundle (bundle)).After very being close to the frame of client's front device (CPE), loop adopts the form of lead-in, and exists with the form of bundle.Therefore, local loop passes two different environment.The part of loop can be arranged in bundle, and loop is sometimes shielded from outside electromagnetic interference and comes here, but but can be crosstalked.After frame, when for most of lead-ins, when this to bundle away from other during to bundle, lead-in is not subjected to cross talk effects usually; But because lead-in does not have conductively-closed, therefore transmission still can be weakened significantly by electromagnetic interference.All have 2 to 8 twisted-pair feeders in many lead-ins, and arrive in a plurality of services under the situation of the ownership of these circuits or connection (the multiplexing or demultiplexing of a service), significantly crosstalking in addition may take place between these circuits of introducing line segment.

Fig. 2 shows common exemplary DSL deployment scenario.All local loops of (L+M) individual user 291,292 pass at least one common binder altogether.Each is with being connected to central office (CO) 210,220 by industrial siding per family.Yet each local loop also can pass different environment and medium.In Fig. 2, L client or user 291 are connected to CO 210 by the combination of using optical cable 213 and copper twisted pairs 217, this typically refer to optical cable to the chamber (Fiber to the Cabinet, FTTCab) or Fiber To The Curb (Fiber to the Curb).From the signal of transceiver 211 among the CO 210, by Optical Network Terminal 215 among optical line terminal 212, the CO 210 and optical network unit (ONU) 218 conversions.Modulator-demodulator 216 among the ONU 218 serves as the transceiver of signal between ONU 218 and the user 291.

Can operate in the such coordination of for example vector quantization (coordinated) mode at the common subscribers feeder that stops in position such as CO 210,218 and ONU 220 (and other).(for example vector quantization ADSL and/or VDSL system) can reach the coordination of signal and processing in the communication system of vector quantization.When many line transmissions from DSLAM or LT were produced jointly by common clock and processor, descending vector quantization will take place.In having the VDSL system of this common clock, crosstalking between the user takes place independently with respect to each audio frequency.Like this, for many users, each downstream tones can independently be produced by public vector transmitter.Similarly, when common clock and processor are used for receiving the signal of many circuits jointly, up vector quantization will take place.In having the VDSL system of this common clock, crosstalking between the user produces independently with respect to each audio frequency.Like this, for many users, each upstream tones all can be come independent process by public vectorial receiver.

M remaining user 292 loop 227 is copper twisted pairs just, refers to optical fiber to office (Fiberto the Exchange, situation FTTEx).Any may and economically feasible the time, FTTCab is better than FTTEx, because FTTCab has reduced the copper part of local loop, thereby has increased accessible speed.The existence of FTTCab loop can throw into question to the FTTEx loop.In addition, wish that FTTCab will become general gradually topology in future.Such topology can cause significant crosstalk interference, and might mean, because the specific environment of its operation, the circuit of different user has different Data-carryings and performance capability.This topology can be that fiber-fed " chamber " circuit and exchange line are mixed in the same bundle.

As can be seen from Figure 2,292 the Line sharing bundle 222 from CO 220 to the user, and do not use this bundle 222 from the circuit between CO210 and the user 291.Further, another bundle 240 for all lead to/from CO 210 and CO 220 with and separately user 291,292 circuit be public.In Fig. 2, far-end cross talk (FEXT) 282 and near-end cross (NEXT) 281 are illustrated as at least two that influence in the circuit 227 that is configured in CO220.

The flow chart of Fig. 4 shows one embodiment of the present of invention.Method 400 is with 410 beginnings, with the maximum allowable number of in the communication system or more circuits according to speed R _MaxBe set to the non-rank R that meets _NCAt 415 places, give any system line of participation condition/reward incentives program then with the value and/or the limitation notification that are used to determine the accordance of any applicable service conditions.Should " communication system " can be any kind system (for example, and can comprise all circuits in single line, many circuits, bundle, cable, whole service merchant's sets of lines, single ISP's all circuits, CO or the zone or the like the DSL system).In 420, use R _MaxFunctional arrangement is according to normal operation transmission data.In 430, can the employed any service conditions of measurement circuitry, for example use the service data of being gathered.In judgement 440, assess accordance then.If circuit does not satisfy accordance, then in 450, keep R _MaxPerhaps with R _MaxBe re-set as R _NCIf circuit satisfies accordance, in 460, keep R _MaxPerhaps with R _MaxBe re-set as R _COMPLYAlternately, when detecting accordance, can be only with R _MaxFrom R _NCDischarge in the restriction.In case carry out the speed adjustment in 450 or 460, circuit returns the operation at 420 places, and can be reappraised afterwards.Method 400 and any other method of the present invention can realize on computer program that this is stated computer program and comprises machine-readable medium and the program command that is included on this machine-readable medium.These program instructions specify one or more a plurality of method disclosed herein.

Whether circuit is had the right to obtain to move the assessment of interests and/or to any other assessment of service data, can be needed as based on the nearest obtainable service data relevant with service conditions, perhaps based on historical data and current data.If the use historical data, can be in any suitable manner weight in addition.For example, can give every circuit and/or service conditions with data weighting vector (W), the function that current like this and weight historical data can be used as the current degree of data is used.For example, if weight vectors is W1=[111], then when estimating accordance, identical weight is gone over three update cycles the data in (for example, sky).If weight vectors is W2=[10000000.5], come from last data of being reported the service conditions data so and have weight 1, the data that come from 7 update cycles (for example, before the week) early have weight 0.5.Ignore the data that come from other update cycles.If wish to use only from bimestrial data of past according to identical weight, adopt one day so during as the update cycle, weight vectors has 60 length, and all be 1 (W3=[111...111 just ,]).According to embodiments of the invention, can use different weight vectors at different service conditionss, for example, depend on whether read as the basis of determining circuit or system operation interests and/or other changes with single.

Except the time of considering service data, whether circuit, system etc. is had the right to obtain the assessment of any operation interests and/or to other assessments of service data, can be needed as based on enough obtainable service datas.For example, in some cases, data acquisition system may break down or by deexcitation, have only in other words very little or do not have an available service data.In these cases, when not having enough data when making reliable assessment basic, system abandons system and/or circuit operation are made any change, perhaps abandons making any restriction and/or available parameter, may be helpful like this.In order to prevent to carry out inappropriate change, the execution of change only can be limited at from the last assessment or the situation of having gathered abundant excessive data in one section official hour.Can use radix technology and data probability distributions to check service data.Can use ripe distribution estimation technique to reduce the influence of past data far away and the data that enhancing is gathered recently, these technology are known to those skilled in the art.If do not satisfy data abundance and time rule, circuit can only keep current state so, makes till the new data that such rule is satisfied up to having gathered.

As shown in Figure 5, an alternative embodiment of the invention adopts slightly different operation to reward and to its adjustment.In method 500, its transmitting uplink data frequency band of adsl line is set to f _Low≤ f _Transmit≤ f _HighUpper limiting frequency f _HighBe used for uplink, and can select, with minimise cross talk or reach other preferred targets in appropriate initial rank.In 520, suitably use this frequency band to operate this circuit then.In 530, measure the accordance of (for example, crosstalking does not surpass specified threshold value), and this accordance preferably can be based on the service data of being gathered with given compatibility standard.In 540, judge accordance with one or more a plurality of service conditionss.If circuit does not meet the service conditions that is adopted, then adopt current frequency bandwidth to continue this circuit of operation in 520.If circuit meets service conditions, then judging that rank (it is different disturbing with any service conditions that adopts) is disturbed in assessment here in 550.If the interference compatibility of circuit operation is exactly a service conditions, judge that so 540 and 550 can merge into a step.If circuit meets service conditions and do not exceed the interference rank, will in 560, increase the upper limit f of frequency band so _HighCan in fact, perhaps, increase f by improving the frequency rank by increasing the highest frequency upper limit of frequency band _HighIn 520, next circuit adopts newly-installed frequency band to move.If the upper end of frequency range is too high, can in 570, reduce f so _High

In other embodiments of the invention, can be so that qualified circuit obtain less restrictive PSDMASK, and ineligible circuit is subjected to more restrictive PSDMASK.In addition, CARMASK and/or BCAP[n] can use in a comparable manner equally.And in certain embodiments, the power spectral density rank of a plurality of frequency bands and any one frequency band can be used for determining accordance.Other operational factors and/or feature are obvious to those skilled in the art.Further, can also use other awards of a plurality of level of a plurality of level of conformance of foundation among the present invention.

More particularly, embodiments of the invention comprise method, device and computer program, the example below can implementing in these methods, device and computer program:

Example 1---only when the DSL service at all identical suppliers in the same cable, when the Maximum tolerance of measuring at all audio frequency places was no more than 11dB, qualified system was to transmit up to the downstream data rate that meets maximum data rate.Can require the appropriate regional power spectral density masks of qualified modulator-demodulator observation, and the measurement of Maximum tolerance should be put on all audio frequency in this mask.When the ISP can't determine that all DSL of himself have used Maximum tolerance in the public domain, maximum data rate should not surpass the non-maximum data rate that meets of the service that is provided in this zone, and still must adhere to adopting power spectral density masks.Further, the transmission descending power of any ADSL service can be limited in not being higher than 20.5dBm.In the situation of all ADSL2, the PSDMASK of programmed represents the maximum power spectral densities that be found simultaneously.If at the appointed time at interval (for example; 15 minutes) the code violation counting measured surpasses 250 (perhaps selected appropriate threshold) in protection place of obtainable maximum impulse, then can require ISP DSM accordance in set place of any Maximum tolerance.

If example 2---identical supplier all DSL route surveys in same-bar cable to given restriction (for example, 11dB or still less) Maximum tolerance in, then qualified system is transmitted with the data rate up to maximum data rate on loop, measured up decay (is for example satisfied the minimal attenuation value, 40dB or approximate 13000 feet loops), and can use power up to 20.5dBm.Qualified modulator-demodulator can be at 138kHz to any PSD value of using the carrier mask that is lower than ISP's regulation between the 500kHz, suppose that this mask is no more than-28dBm/Hz at any frequency place that is lower than 138kHz, and be no more than-32dBm/Hz at any frequency place that is higher than 138kHz.In any use of such long range compliance, should satisfy all POTS-protection requirements.

If example 3---in a bundle on all audio frequency of all identical supplier's circuits, measured up MAXSNRM is no more than 11dB, (for example then be shorter in length than given maximum line length, 9000 feet or the up decay of measuring are lower than 30dB) qualified ascending communication system can be used the audio frequency that is up to audio frequency 63 on the circuit, transmit with the data rate of height to 2.5Mbps.Under all such situations, it is other that PSD can be no more than given even lower level.Do not find that MAXSNRM is that the qualified up-link of 11dB is transmitted with the data rate that is not higher than 384kbps.

Example 4---if the MAXSNRM on all audio frequency (just frequency band is preferred) is equal to or less than 11dB, and MAXATP＜10dBm, and then qualified VDSL system correctly carries out the PSDMASK of limited ISP's programming.To being restricted to of PSDMASK, must abide by (for example, between 1.1 to 4.4MHz) applicable PSD constraint in given frequency range.

In the system that uses such as the top method that proposes, technology and device, observe the DSL circuit of margin limits with good conditionsi, characteristic and/or parameter, will help to alleviate the negative effect that causes by crosstalking in the DSL system, too high power etc. other users' signal.The availability excitation user that higher data rate and/or other operations are rewarded adopts rational margin limits etc.It will be understood by those skilled in the art that according to the present invention, can in various communication systems, adopt other service conditions and award.

Adopt all technology as disclosed herein, method and apparatus, can reach is not only the DSM achievement of a cover maintenance parameters.DSM can also comprise the spectrum-management standards ability, to distinguish and to adjudicate DSL spectrum compatible in the cable.If set about carrying out compatibility specification task, for example adopt embodiments of the invention, then general high speed DSL disposes the possibility more that becomes, and can be used for determining and encourage DSL deployment faster.

The ADSL downstream transmission signals typically has-power spectral density (PSD) restriction of 40dBm/Hz.Actual PSD can be up to more than the 2.5dB, but it on average must be on this level.In addition, though-40 roughly are meant most of frequency bands, but can be in the annex of various criterion and in T1.417 spectrum-management standards (other countries may have the document that is similar to the T1.417 spectrum-management standards) for example to the North America, find accurate PSD template at zones of different.The ADSL down-link transmitter can use the through-put power up to 20.5dBm.Unfortunately, only under the situation that whole downstream bands is activated, 20.5dBm could with should-the 40dBm/Hz restriction is allowed simultaneously, and the situation that whole downstream bands activates only accidental generation in short loop.Typically, short loop does not require the through-put power of 20.5dBm, and this is because the maximum data rate that can reach is higher than desired speed on these short loops usually far away.On the other hand, usually must use the long loop of whole 20.5dBm through-put powers, but the restriction owing to-40dBm/Hz PSD is limited to the numerical value that is low to moderate 12-13dBm.Yet as what it will be appreciated by those skilled in the art that, long loop requires higher power, and has seriously limited DSL generality in the loop qualification for inappropriate transmit power restrictions of these longer DSL loops.The embodiment of the invention can help to provide more effectively and the adapt that still less bothers, come to realize better communication system for the various users that share bundle, this adapt is the adapt at the variation of these types of the demand of loop-length and power and restriction.

Extra 6dB through-put power (when still being lower than 20.5dBm) is about 1000 feet additional range on any long loop almost.Be low to moderate on the speed of 100kbps, 1000 feet additional range can change the DSL economy significantly.Like this, spectrum management in advance allows and encourages on the short loop more broadband, more high-power ADSL downlink transfer, thereby set up the maximum of crosstalk enter in the weakened longer loop, this longer loop produces crosstalking and must transmit with lower power still less.If short loop is positioned at the older longer ADSL signal based on CO and shares on the remote fiber feedback terminal (remote-fiber-fed terminal) of bundle, then the ADSL situation can worsen more.Adsl deployment surpasses 90% in the North America is disposed, increased the scope of being put into practice caused problem by these.

The embodiment of the invention provides spectrum management system, method, device and the technology based on excitation, with more reasonably using of encouragement telecommunication system resources, and hinders those practices that the family causes disadvantaged user's service disruption and/or degeneration.In certain embodiments, controller can encourage the MAXSNRM parameter correctly to use more widely, and this parameter is left in the basket at present or is observed mistakenly with very high ratio in DSL basis, North America.Other are the themes of these technology about tolerance limit and/or the parameter that influences performance too.Can reach desired excitation by allowing circuit to enjoy interests, to enjoy the interests that can't obtain for those circuits of not observing this restriction, the consistent and/or general use of this circuit is just at 11dB or other Maximum tolerance of even lower level.For example, the circuit of allow observing the Maximum tolerance restriction in ADSL1 transmits with height to the speed of 7Mbps, and the circuit that will show excessive 17dB or more tolerance limits is limited in lower 1.5Mbps speed.Like this, excitation ISP and seller alleviate and/or reduce overall crosstalk by correct and use " based on the courtesy of parameter " widely.As what it will be appreciated by those skilled in the art that, it is possible that the probability that reduces service disruption under such practice is assessed.In another one embodiment of the present invention, when loop-length during greater than the 12k foot (for example, when assessing) by the up decay of report, if for the speed of height to 768kbps, tolerance limit＜MAXSNRM=11dB, then controller can allow the 20.5dBm transmission on the adsl loop road, and retrains without any PSD.

Embodiments of the invention can also with the symmetric services compatibility such as HDSL (perhaps Wei Lai SHDSL), this symmetric services and ADSL share bundle.Causing a consideration of-40 dBm/Hz PSD masks of ADSL is that the descending ADSL near-end cross (NEXT) that enters up HDSL receiver can jeopardize HDSL (or SHDSL).

Probability can clearly be expressed maximum length HDSL and whether share bundle with the very long ADSL that needs 20.5dBm power (and the PSD that is higher than-40 dBm/Hz).If HDSL only exist only in the DSL circuit 2% on, and the long ADSL conditional probability adjacent with HDSL only is 10% (is not very possible because of long transmission line) in bundle (perhaps cable), this probability is 0.02% so.Further, crosstalking between these two circuits can cause the incompatibility of HDSL service disruption under 1% worst case rank.In addition, there are some so long ADSL all just can cause problem (remind: correct MAXSNRM observes the power that will reduce most of adsl circuit) with maximum power transfer.Like this, the probability of being assessed is reduced to far below 0.000002, perhaps each is in 1,000,000 twice (if no matter the probability during-40 dBm/Hz transmission that allows with maximum on all frequencies well below all ADSL as what be allowed in current T1.417, is why).

Like this, under the rule of flexibility formerly, very low, but be to have bigger incompatible probability.No matter be that long loop ADSL user's that possible millions of speed is lowered to save the loss probability on the small amount of H DSL only, still substitute small amount of H DSL with fiber optic circuit, the probability of reduction/replacement demand will be higher than in said fixing/static spectrum management according to the probability in the management that the present invention is based on excitation.Herein in some examples of Tao Luning, loop information operation report and/or that assess out, for example loop-length and decay as the input of the judgement of using 20.5dBm, can bring the marked improvement of DSL service.As what it will be appreciated by those skilled in the art that, use extra information can further reduce the probability of service disruption.

Further, point out mistakenly that sometimes the ISP does not understand other loops in the bundle.In fact, the ISP can carry out " loop is formed report " on any circuit, and finds the situation with other services in a bundle or the cable.If these records come forth and be obtainable for any competitive service supplier, and by using these records to select pairing from any DSL service of current service supplier, then these records can not use under the situation of not adjusting the non-fact.These records and noise/crosstalk in measured or the ADSL system reported can also be connected then.Then just know the position of the HDSL that may be affected on a small quantity at an easy rate, also be easy to replace their (perhaps being more preferably the DSL that still can work) with optical fiber.

Higher upstream data rate is normally attracting, particularly for some application.The ADSL2 standard has annex J and M, allows wideer upstream bandwidth, and allows the overlapping of uplink and downlink at least in theory.The NEXT that enters descending ADSL receiver that comes from the increase that causes thus for the worry of the wideer upstream bandwidth of ADSL2 modulator-demodulator.G.992.2/5 the noise of the relative loop-length of certain hypothesis takes place in the supposition of annex cut-off frequency of advising and bandwidth, and this is can not be applied under most of concrete conditions.Use one or more a plurality of embodiment discussed above, can be used in some cases in following getable extra bandwidth of these standards.

In the another one example, the service data of being gathered can show, observe the uplink of given circuit of the MAXSNRM of 11dB, and can not have the PSD constraint and under total uplink transmit power of 13.5dBm, use wideer upstream transmission frequency band up to audio frequency 64.So most of uplink have the PSD that goes up being lower than of allowing-38dBm at whole upstream bandwidth (perhaps other values, from corresponding annex).Only near the loop the length restriction of the speed uplink of trying hard to reach can use full power.The probability of the descending ADSL of one of these length-limit loops next-door neighbour can not determine performance characteristic or obtainable operational factor.On the contrary, upstream cut-off frequency can be used as the function of report adsl line and is programmed by dynamic controller (for example, the DSL optimizer) and adjust, and reaches its desired performance level up to these circuits.Obviously this frequency can rely on situation, and can dynamically be provided with according to quite simple program.Basically, only under following situation speed uplink will increase:

1---there are not other downstream systems report; And/or

2---system in future has the low probability of service disruption or problem.

This is the example of the reaction of the dynamic and on-fixed of another one, is reflected in the deployment the higher DSL speed of excitation significantly in then.According to the present invention, any ISP who wants to operate in the speed higher than the current speed that allows follows understanding to the accordance program with needs.
