Each overlay network as shown in Figure 4, a side ports of its information source node 11,12,13 equal access carrier channel routers 8, and the opposite side port of 91,92,93 access carrier channels of overlay node router 8.Although it is also not shown among the figure, but owing to generally baseband signal is carried out the uplink and downlink transmission that is separated with the light signal form between information source node and the overlay node, thereby the signal of carrier channel router 8 handled each overlay network all is respectively the up link and the down link of this overlay network independently to be carried out.Specifically will in follow-up explanation, describe in detail.
Carrier channel router 8 shown in Fig. 4 mainly comprises three parts, be specially traffic detection unit 4 that mixes unit, road 2, constitutes by n traffic detection module 40 and the monitoring host computer unit 3 that plays the management control action, formation scheduling unit jointly between traffic detection unit 4 and the monitoring host computer unit 3.
Mix unit, road 2 and include n communication link, the every pair of communication link and a corresponding connection of overlay network, be used to finish and each information source node of n overlay network and the electric connection between each overlay node, particularly, each communication link has up link and down link, insert in the up link and down link of overlay network correspondingly respectively, and make each overlay network all have the summation of the carrier channel of all overlay networks.Communication overlay system with three overlay networks only is shown in the present embodiment, thereby, variable n=3, in theory, the numerical value of n is not subjected to the restriction of the embodiment of the invention, and it can be any one positive integer greater than 2, for the convenience of explaining, in the following description, still have the example with the concrete number of n designate, those skilled in the art all know this and one refer to relation.
This scheduling unit is mainly used in the signal of intercepting and capturing each overlay network and detects its actual demand for carrier channel, realizes the dynamic dispatching of carrier channel between at least two overlay networks.The work of scheduling unit is mainly finished jointly by traffic detection unit 4 and monitoring host computer unit 3.Traffic detection unit 4 is made of n traffic detection module 40 (consulting Fig. 5), do not have direct electrical connection between n the traffic detection module 40, but electrically connect with this monitoring host computer unit 3 respectively, monitoring host computer unit 3 need carry out the pre-of parameter if adjust to each traffic detection module 40 in the traffic detecting unit 4 on the one hand, on the other hand, each traffic detection module 40 final data that produce and signal also will be submitted to this monitoring host computer unit 3 and focus on.
Fig. 5 shows the part of concrete structure of the carrier channel router of the present invention 8 of Fig. 4, it represented mix unit, road 2 in the carrier channel router 8 each to communication link and and traffic detection module 40, monitoring host computer unit 4 between electrical connection and structure form.
Mix unit, road 2 and comprise n the communication link that constitutes jointly by down link and up link as shown in Figure 5, each communication link inserts in the overlay network, particularly, first overlay network of forming with information source node 11 and overlay node 91 is an example, the down link of information source node 11 inserts in the down link shown in Figure 5 behind incoming carrier channel router 8 immediately among Fig. 4, exports in the down link of overlay node 91 after corresponding the processing.Principle when up is identical, also is after the up link of overlay node 91 among Fig. 4 enters up link shown in Figure 5 one tunnel transmission, to be fed in the up link of information source node 11.By the combination of Fig. 4 and Fig. 5 as can be seen, carrier channel scheduling method of the present invention is to the scheduling process of a plurality of overlay networks, be actually based on to the intercepting and capturing of the upward signal of each overlay network and downstream signal, processing, reduce the former link of feed-in again and realize.
See also Fig. 5, in down link, the signal of telecommunication is intercepted and captured and be converted to information source node going into modular converter 51 places, generally speaking, be with light signal between information source node and the overlay node, the signal of telecommunication or wireless signal transmit, no matter concrete signal format how, being provided with of modular converter 51 of going into herein is that mainly the conversion of signals with existing form is the signal of telecommunication that carrier channel router 8 can be discerned processing, in like manner, be provided with at the transmission end of this down link and go out modular converter 56 accordingly, its purpose is to be reduced into original signal format so that in the former link between feed-in information source node again and the overlay node with handling the back signal of telecommunication in this down link.Because transmission medium at present comparatively commonly used mostly is optical fiber, thereby present embodiment can to go out that modular converter 56 refers in particular to be that module is received/sent out to light with going into modular converter 51/.
Going into modular converter 51 and going out between the modular converter 56, according to the transmission direction of downstream signal, comprising shunt module 52 successively, close road module 53, up-conversion module 54 and down conversion module 55.
Please in conjunction with Fig. 3 and Fig. 5, the signal of telecommunication that process is gone into after modular converter 51 is handled is the downgoing baseband signal that is derived from the current information source node, it includes several and belongs to the intrinsic carrier channel of current information source node, described shunt module 52 is used for the downgoing baseband signal of current information source node is carried out shunt, be divided into n branch signal, as previously mentioned, because there be n overlay network in the system, thereby, n branch signal just distribute to a described n overlay network in the corresponding downstream link that mixes in the unit, road 2 of the carrier channel router 8 that inserts respectively so that in each described down link respectively to closing the road from the individual different branch signal of the n of n overlay network.
Also be, what be connected with this shunt module 52 as shown in Figure 5 closes road module 53 except receiving the next branch signal of one tunnel current link shunt module 52 distribution, also receive the input of each one road branch signal of other n-1 overlay network, because each branch signal has all comprised all carrier channels of the original information source node under it, thereby, shunt module 52 shown in Figure 5 is closed n behind the road in the formed composite downstream baseband signal from the branch signal of different overlay networks, to comprise all carrier channels from all information source node, also be the summation of all carrier channels of whole communication overlay system.Shown in Figure 5 only is a pair of communication link of carrier channel router 8, and for remaining communication link too, the shunt module 52 of the down link of every pair of communication link all obtains the summation of all carrier channels of whole communication overlay system.
Close in the composite downstream baseband signal that forms behind the road and comprised all carrier channels although close road module 53,, under the initial condition, perhaps under the general state, non-carrier channel from current overlay network information source node all is in closed condition.Open and close for carrier channel in the downgoing baseband signal are to control for the pad value of the concrete carrier channel of difference by the up-conversion module 54 in the down link to realize.
Up-conversion module 54 in the down link shown in Figure 5 will be closed the composite downstream baseband signal of road formation and be carried out mixing, be up-converted into intermediate-freuqncy signal, it can receive the instruction of described monitoring host computer unit 3, according to this instruction to controlling step by step several times by the pad value of wherein each carrier channel, when monitoring host computer unit 3 sends these up-conversion module 54 certain carrier channels of unlatching of instruction indication, this up-conversion module 54 reduces the pad value of this carrier channel step by step, its gain is improved constantly until this carrier channel open, just can come into operation.On the contrary, close certain carrier channel if desired, then only need to send corresponding instruction by monitoring host computer unit 3, the pad value of up-conversion module 54 corresponding these carrier channels of raising reduces its gain and gets final product.Certainly, in the down link of certain carrier channel at current overlay network, enabled/when closing, for the down link of other overlay network, this carrier channel just is in closes/stand-by state, also promptly, the pad value of this carrier channel being carried out adaptive adjustment in the up-conversion module of the down link of other overlay network makes it to close.Concrete certain carrier channel is enabled in which overlay network, decides on the instruction of monitoring host computer unit 3.
Up-conversion module 54 is just carried out mixing after baseband signal being converted to intermediate-freuqncy signal and carrying out the enabling and close processing of carrier channel once more in described down conversion module 55, make it down-conversion and be reduced into baseband signal.Baseband signal after the reduction is gone out modular converter 56 and converts original signal format to by described, behind the light signal form in the present embodiment, just again in the former link of feed-in overlay network, import after carrier channel router 8 is handled, again in the down link of feed-in overlay node 91 from information source node 11 as shown in Figure 4.
Please in conjunction with Fig. 4 and Fig. 5, the up link of mixing unit, road 2 to the uplink baseband Signal Processing basically with down link to downgoing baseband Signal Processing contrary, but its treatment step relative complex.Particularly, the side signal transmission of pressing the uplink baseband signal to, include modular converter 51 ' successively, traffic detection module 40, shunt module 52 ', close road module 53 ', up-conversion module 54 ', down conversion module 55 ' and go out modular converter 56 ', wherein traffic detection module 40 detects by uplink baseband signal in the sampling up link, the result of its output directly offers monitoring host computer unit 3 and uses, go into modular converter 51 ' and go out modular converter 56 ' then finish with down link in go into modular converter 51 and go out modular converter 56 identical functions, do not give unnecessary details at this.In like manner, the shunt module 52 ' of up link also is divided into the uplink baseband signal n road branch signal, except that one tunnel follow-up the closing the road module 53 ' that exports current up link to, other branch signal exports the road module of closing of the up link of other overlay network respectively to and closes the road, thus, closing in the road module 53 ' of each up link, just can become compound uplink baseband signal with closing the road from the different branch signal in the n road of n overlay network, this compound uplink baseband signal has comprised all carrier channels of all overlay networks equally, because carrier channel is mainly provided by information source node, the employed carrier channel of up link is retrained by the employed carrier channel of down link basically, thereby, in up link, can carry out the control of enabling and closing of carrier channel, up-conversion module 54 ' can only be responsible for that compound uplink baseband signal is carried out mixing and become intermediate-freuqncy signal, after down conversion module 55 ' only is responsible for this intermediate-freuqncy signal down-conversion is reduced into baseband signal, is reduced into light signal and gets final product in the up link between feed-in overlay node and the information source node again through going out modular converter 56 '.
In up link shown in Figure 5, has a traffic detection module 40, also there is a traffic detection module respectively in up link in the unit, mixed road 2 of corresponding other overlay network, the function of the original traffic data statistical under all being used to finish, the traffic detection module 40 common compositions traffic detection unit 4 shown in Figure 4 in a plurality of up links.
This traffic detection module 40 comprises comparator 41 sum counters 42; comparator 41 can be by monitoring host computer unit 3 default comparison threshold values; this comparison threshold value has characterized the performance number of normal telephone traffic signal; also be; when the power magnitude of uplink baseband signal meets or exceeds this performance number; promptly looking current uplink baseband signal is normal telephone traffic signal, otherwise is considered as noise, and this comparison threshold value can be preset by the 3 pairs of comparators 41 in monitoring host computer unit with interactive means by the user.Monitoring host computer unit 3 is by official hour section of user preset, in this stipulated time section, uplink baseband signal in the comparator 41 circulation Direct Sampling up links compares, when the amplitude of uplink baseband signal during greater than this comparison threshold value, send a signal to the counter 42 that electrically connects with comparator 41, current uplink baseband signal is added up, behind this official hour end cycle, counter 42 just produces an original traffic data and exports to 3 uses of monitoring host computer unit with the form of signal.Because the use amount of carrier channel finally is to be determined by up user's traffic request in the overlay network, thereby, the statistics of utilizing original traffic data in the up link is so that the real time telephone traffic in the current overlay network of follow-up generation, is necessary for the carrier channel scheduling of whole communication overlay system.
In the described comparison threshold value of user preset, also should preset (or by monitoring host computer unit default setting) telephone traffic unlatching value and a telephone traffic close value simultaneously, the meaning that telephone traffic unlatching value is characterized is meant that the monitoring host computer unit should be opened other carrier channel and use for current overlay network when the real time telephone traffic number in the current overlay network that compares with it during greater than this telephone traffic unlatching value; In like manner, the meaning that the telephone traffic close value is characterized is meant when the real time telephone traffic number in the current overlay network that compares with it during less than this telephone traffic close value, but monitoring host computer unit 3 marks and close idle any carrier channel for future use.Telephone traffic unlatching value and telephone traffic close value equivalence.
After this monitoring host computer unit 3 obtains 42 final each original traffic data that produces of individual count device of each traffic detection module 40, calculate the telephone traffic that this original traffic data comprises by known conversion method, this telephone traffic is the real time telephone traffic in the described stipulated time section.This real time telephone traffic in a certain overlay network is compared with described default telephone traffic unlatching value and telephone traffic close value, when real time telephone traffic during greater than this telephone traffic unlatching value, the line be busy of then representing current overlay network, the carrier channel that needs other overlay network of scheduling, the carrier channel that has been labeled as other idle overlay network is just searched in monitoring host computer unit 3 at this moment, and implement pad value by the 54 pairs of corresponding carrier channels of up-conversion module in the down link that mixes unit, road 2 at current overlay network accordingly and reduce operation, improve constantly the gain of corresponding carriers channel, be unlocked until this carrier channel, at this moment, promptly finish from the step of the information source node scheduling carrier wave channel of other overlay network, the channel resource of current overlay network just is able to dilatation.And when this real time telephone traffic in a certain overlay network during less than this telephone traffic close value, the circuit that then shows current overlay network is comparatively idle, has the not carrier channel of usefulness, for ease of other overlay network scheduling, need by monitoring host computer unit 3 marks not the state of the carrier channel of usefulness be idle, by this, scheduling to whole communications coverage network just can be realized by searching this idle carrier channel in monitoring host computer unit 3.Sign to the state of carrier channel, both can also calculate in real time one by one by each carrier channel of traversal and determine by monitoring host computer unit 3, also can be in the monitoring host computer unit 3 bist data tables identification-state as required, concrete realization technology those skilled in the art all know.
When using optical fiber to transmit between information source node and the overlay node, go into modular converter 51 for the uplink and downlink link homonymy of unit, mixed road 2 shown in Figure 5,51 ' and go out modular converter 56,56 ' can directly adopt light to receive/send out module, when adopting cable, can adopt serial ports to receive/module, its major function is to finish the conversion of the signal of telecommunication and other form signal, and those skilled in the art all know its accommodation.
The manufacturer is when its communication equipment of design such as base station, generally can take into account the problem of carrier channel dilatation, thereby be provided with standby carrier channel, these standby carrier channels are in closed condition in the ordinary course of things, need adjust its pad value by the up-conversion module 54 in the communication link, for this situation, monitoring host computer unit 3 has the step of a special disposal, it transfers in the carrier channel router 8 the original traffic data of the traffic detection module 40 in the corresponding up link receiving certain overlay network, and after carrying out the calculating of real time telephone traffic, compare with telephone traffic unlatching value, in case greater than this telephone traffic unlatching value, then at first send a signal to the up-conversion module 54 of mixing the down link in the unit, road 2 with this overlay network accordingly, make its pad value that reduces corresponding standby carrier channel step by step, come into operation so that the gain of the standby carrier channel that this overlay network self is equipped with improves constantly until being in opening.
Secondly when the real time telephone traffic of this overlay network during greater than the summation of its standby carrier channel and carrier channel commonly used, then need to dispatch the carrier channel of other overlay network, this moment, monitoring host computer unit 3 was in accordance with aforesaid method, travel through the carrier channel of all overlay networks, the pad value that finds the carrier channel of corresponding free time and adjust corresponding idle carrier channel in the up-conversion module 54 of current overlay network is opened until this carrier channel and is used.
